C# Object Panels - c#

The problem I'm having is where I can successfully use the RoomID of the Room object I've created, but not the panel. Here is the function where I set the label to the name of the room. (This is my Form1.cs)
public partial class Form1 : Form
{
Room ThisRoom = new Room();
public Form1()
{
InitializeComponent();
this.Text = "Aquinas College Master Controller";
}
private void roomDesignerToolStripMenuItem_Click(object sender, EventArgs e)
{
new RoomDesigner().Show();
}
private void button1_Click(object sender, EventArgs e)
{
roomsToolStripMenuItem.DropDownItems.Clear();
foreach (var Room in Global.Aquinas.Aquinas)
{
ToolStripMenuItem NewItem = new ToolStripMenuItem(Room.RoomID);
NewItem.Name = Room.RoomID;
NewItem.Click += new EventHandler(ItemClick);
roomsToolStripMenuItem.DropDownItems.Add(NewItem);
}
}
void ItemClick(object sender, EventArgs e)
{
ToolStripItem item = (ToolStripItem)sender;
label2.Text = item.Name;
foreach (var Room in Global.Aquinas.Aquinas)
{
if (Room.RoomID == item.Name)
{
ThisRoom = Room;
break;
}
}
Panel RoomPanel = ThisRoom.Panel;
RoomPanel.Size = new Size(607, 304);
RoomPanel.Location = new Point(144, 27);
RoomPanel.BackColor = Color.White;
this.Controls.Add(RoomPanel);
}
}
This is some of my code for the room object. (This is in Room.cs)
public class Room
{
private List<CtrlComputer> _Computers;
public List<CtrlComputer> Computers
{
get { return _Computers; }
set { _Computers = value; }
}
private string _RoomID;
public Room()
{
_Computers=new List<CtrlComputer>();
}
public string RoomID
{
get
{
return _RoomID;
}
set
{
_RoomID = value;
}
}
public Panel Panel
{
get
{
return _Panel;
}
set
{
_Panel = value;
}
}
private Panel _Panel;
}
And here is where I register the panel which I have just put my designs on, to a new room. (This is some of my RoomDesigner.cs)
public partial class RoomDesigner : Form
{
Room NewRoom = new Room();
Panel RoomDesignerPanel = new Panel();
public RoomDesigner()
{
InitializeComponent();
RoomDesignerPanel.Size = new Size(607, 304);
RoomDesignerPanel.Location = new Point(144, 27);
RoomDesignerPanel.BackColor = Color.White;
this.Controls.Add(RoomDesignerPanel);
textBox1.ForeColor = SystemColors.GrayText;
textBox1.Text = "Enter Computer ID Here";
this.textBox1.Leave += new System.EventHandler(this.textBox1_Leave);
this.textBox1.Enter += new System.EventHandler(this.textBox1_Enter);
textBox2.ForeColor = SystemColors.GrayText;
textBox2.Text = "Enter Room ID Here";
this.textBox2.Leave += new System.EventHandler(this.textBox2_Leave);
this.textBox2.Enter += new System.EventHandler(this.textBox2_Enter);
}
private void textBox1_Leave(object sender, EventArgs e)
{
if (textBox1.Text.Length == 0)
{
textBox1.Text = "Enter Computer ID Here";
textBox1.ForeColor = SystemColors.GrayText;
}
}
private void textBox1_Enter(object sender, EventArgs e)
{
if (textBox1.Text == "Enter Computer ID Here")
{
textBox1.Text = "";
textBox1.ForeColor = SystemColors.WindowText;
}
}
private void textBox2_Leave(object sender, EventArgs e)
{
if (textBox2.Text.Length == 0)
{
textBox2.Text = "Enter Room ID Here";
textBox2.ForeColor = SystemColors.GrayText;
}
}
private void textBox2_Enter(object sender, EventArgs e)
{
if (textBox2.Text == "Enter Room ID Here")
{
textBox2.Text = "";
textBox2.ForeColor = SystemColors.WindowText;
}
}
private void button1_Click(object sender, EventArgs e)
{
CtrlComputer NewComputer = new CtrlComputer();
NewComputer.ComputerID = textBox1.Text;
NewComputer.Text = NewComputer.ComputerID;
NewComputer.Parent = RoomDesignerPanel;
RoomDesignerPanel.Controls.Add(NewComputer);
NewRoom.Panel = RoomDesignerPanel;
NewRoom.Add(NewComputer);
}
When I try to reload that panel, the RoomID of that object is returned fine, yet the panel is not. Any ideas?
Edit: Sorry for the lack of clarity in my post, first posts aren't always easy.
The panel is created in the designer, but I tried private Panel Panel1 = new Panel(); with no luck. My current problem is that in Form1.cs, the program will throw "Cannot access a disposed object", but I followed the guide here https://msdn.microsoft.com/en-us/library/82785s1h(v=vs.110).aspx .

What you are looking to do is swap between a collection of Panel objects (kind of like your own version of TabPages). To do this you need to create each of the Panel objects (You do this in RoomDesigner, which is fine, but there is a catch: see * below). With that collection in hand, when you want to show it on the form, you need to remove the panel1 the designer code created (Controls.Remove(panel1)) and insert your new one (Controls.Add(RoomPanel)).
Since Controls utilize system resources, make sure to Dispose any control you will no longer use. Here is an example method:
//Initial case where no room has been displayed yet and panel1 is still valid
private Panel CurrentPanel = null;
public void SwapPanel(Panel p)
{
//If no panel has been placed yet, get rid of the default one
if (panel1 != null)
{
//we should never need the designer panel again, so dispose it
panel1.Dispose();
this.Controls.Remove(panel1);
}
else
{
//we may return to this panel later, so don't dispose it
this.Controls.Remove(CurrentPanel);
}
CurrentPanel = p;
this.Controls.Add(p);
}
When you finally close out and no longer need your Panels stored in your Room collection, make sure to Dispose them. (However, if your whole program is exiting at that point then it doesn't matter, but do it anyway as good practice)
*When you close any RoomDesigner form (or any form), all controls it contains in 'Controls' will be disposed, even if you are using them elsewhere. To prevent this, remove the controls you want to preserve from the RoomDesigner Controls collection before it is closed.

how to call timer in UC Control in Form Main?

Timer1 not start when add new User Control.I have 1 User Control (UC_Machine).And when load Form Main I using timer execute SQL query in query variable to get data from table [tbl_FF_Trigger]
I have 1 User Control (UC_Machine).And when load Form Main I using timer execute SQL query in query variable to get data from table [tbl_FF_Trigger]
-Code in UC_Machine:
private void UC_Machine_Load(object sender, EventArgs e)
{
timer1.Start();
}
private void timer1_Tick(object sender, EventArgs e)
{
string query = "SELECT CRDName, PartNumber ,DefectName FROM [tbl_FF_Trigger] where Machine = '" + Machine + "'";
db.fillDataGridView(query, dataGridView1);
dataGridView1.BackgroundColor = Color.White;
dataGridView1.RowHeadersVisible = false;
dataGridView1.Update();
dataGridView1.Refresh();
}
Code in form MAIN. Will get the information of the machines from the function Machine_Infor.GetMachine_Infors(). It will then create a UC_Machine array from that information. If the machine in the array does not already exist in the panellayout, it will be added to the panellayout.
In addition, it also checks if the machine exists in the tbl_FF_Trigger table. Otherwise it will delete the machine from the panellayout.
private void Main_Load(object sender, EventArgs e)
{
Get_Infor();
}
private void Get_Infor()

System.Timers.Timer timer = new System.Timers.Timer();
timer.Interval = 3000; // Thời gian chạy (5000 milliseconds = 5 second)

itemFoods.Remove(uc);
uc.Dispose();
}
break;
}
}
}
}
}
Code working OK when load Form. when tbl_FF_Trigger add new value myFlowLayoutPanel1 new UC_Machine
but timer1 not start. I know this because the datagirdview has no data in the newly added UC_Machine.I want when myFlowLayoutPanel1 adds 1 UC_Machine, timer1 will start
Anyone have any advise or solution for this case, please help me. Thanks a lot!
Your question is how to call timer in UC Control in Form Main. The main form is trying to GetInfo from the UC but consider that this might be "backwards" and that the UC Control should be notifying Form Main when it gets the new info instead. Here's what I mean:
Your UC has its own timer1 (we'll get timer1 started don't worry). What main form needs is to be notified when a new query is available in one of the UCs. Giving main form its own timer will interfere with an otherwise-orderly process. Consider making an event in your UC as shown and fire it whenever UC is done getting a new query.
UserControlMachine
Example: UC starts its own timer1 and fires RecordsChanged event when new query completes.
public partial class UserControlMachine : UserControl
{
public UserControlMachine()=>InitializeComponent();
public BindingList<Record> Records { get; } = new BindingList<Record>();
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
timer1 = new Timer { Interval = 2500 };
timer1.Tick += onTimer1Tick;
timer1.Start();
dataGridView1.DataSource = Records;
Records.Add(new Record()); // <- Auto-generate columns
dataGridView1.Columns[nameof(Record.DefectName)].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;
}
private System.Windows.Forms.Timer timer1;
private void onTimer1Tick(object sender, EventArgs e) => queryDB();
private void queryDB()
{
// S I M U L A T E D Q U E R Y R E S U L T
Records.Clear();
for (int i = 0; i < Rando4Test.Next(1,5); i++)
{
Records.Add(new Record
{
CRDName = $"CRD-{(char)Rando4Test.Next(65,70)}{Rando4Test.Next(100, 200)}"
});
}
// Notify the Main Form that something has changed.
RecordsChanged?.Invoke(this, EventArgs.Empty);
}
public event EventHandler RecordsChanged;
// For testing purposes
public static Random Rando4Test { get; } = new Random();
}
Main Form
All the main form has to do is listen for RecordsChanged events.
public partial class Form1 : Form
{
public Form1() => InitializeComponent();
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
// Simulation: Add 2 machines
for (int i = 0; i < 2; i++)
{
var machine = new UserControlMachine
{
Size = new Size(myFlowLayoutPanel1.Width - SystemInformation.VerticalScrollBarWidth, 200),
BorderStyle = BorderStyle.FixedSingle,
};
myFlowLayoutPanel1.Controls.Add(machine);
// Listen for new query results
machine.RecordsChanged += onAnyUCRecordsChanged;
}
}
private void onAnyUCRecordsChanged(object sender, EventArgs e)
{
int totalDefects = 0;
foreach (var machine in myFlowLayoutPanel1.Controls.OfType<UserControlMachine>())
{
totalDefects += machine.Records.Count;
}
Text = $"Main Form - Total Defects: {totalDefects}";
}
}
WHERE Record class represents a DataGridViewRow
public class Record
{
public string PartNumber { get; set; } =
Guid.NewGuid().ToString().Substring(0, 13).ToUpper();
public string CRDName { get; set; }
public string DefectName { get; set; } = "Unknown Error";
}

I open 5 different forms via Form1 but i can't save all positions

I have a project and I'm locked. I open different forms on Form1 you see below in the code. I did this with "notifyIcon". Instead of opening 5 different forms, I am bringing one by changing the form. I have 5 forms on my screen. But my problem is; I can save the locations of the forms. Technically they all come from the same form, so they all start from the same position. Do you have a recommendation?
Edit :
A new idea came to mind. but I need your help again. when I close the form, I can save the form's position to a TxT file and manually start the positions with the positions from TxT when the forms are opened.
private void Form1_Load(object sender, EventArgs e)
{
this.Hide();
string dosyaYolu = #"D:\color\colors.txt";
string[] satirlar = File.ReadAllLines(dosyaYolu);
}
private void tCKToolStripMenuItem_Click(object sender, EventArgs e)
{
string dosyaYolu = #"D:\color\colors.txt";
string[] satirlar = File.ReadAllLines(dosyaYolu);
string tckRenk = satirlar[0];
Color tckColor = System.Drawing.ColorTranslator.FromHtml(tckRenk);
Form2 tckForm = new Form2();
tckForm.Opacity = .50;
tckForm.TopMost = true;
tckForm.BackColor = tckColor;
tckForm.LabelText = "TCK";
tckForm.Show();
}
private void aDAToolStripMenuItem_Click(object sender, EventArgs e)
{
string dosyaYolu = #"D:\color\colors.txt";
string[] satirlar = File.ReadAllLines(dosyaYolu);
string adaRenk = satirlar[1];
Color adaColor = System.Drawing.ColorTranslator.FromHtml(adaRenk);
Form2 adaForm = new Form2();
adaForm.Opacity = .50;
adaForm.TopMost = true;
adaForm.BackColor = adaColor;
adaForm.LabelText = "ADA";
adaForm.Show();
}
You can set From Location
Form frm2 = new Form();
frm2.StartPosition = FormStartPosition.Manual;
frm2.Left = 500;
frm2.Top = 500;
frm2.Show();
public static class extensions

}
if (form.ShowInTaskbar)
{
string windowState = Enum.GetName(typeof(FormWindowState), form.WindowState);

}
}
}
}
catch
{

}
}
public static void LoadFormSizeAndLocation(this Form form)
{
try
{
using (RegistryKey key = Application.UserAppDataRegistry.OpenSubKey(form.Name))
{
if (key != null)
{
form.Left = (int)key.GetValue("Left", form.Left);
form.Top = (int)key.GetValue("Top", form.Top);
form.Width = (int)key.GetValue("Width", form.Width);
form.Height = (int)key.GetValue("Height", form.Height);
// Move window into visible screen bounds if outside screen bounds (prevent off-screen hidden windows)
Rectangle screenRect = SystemInformation.VirtualScreen;
if (form.Left < screenRect.Left)
form.Left = screenRect.Left;
if (form.Top < screenRect.Top)
form.Top = screenRect.Top;
if (form.Right > screenRect.Right)
form.Left = screenRect.Right - form.Width;
if (form.Bottom > screenRect.Bottom)
form.Top = screenRect.Bottom - form.Height;
if (form.ShowInTaskbar)
{
string windowState = Enum.GetName(typeof(FormWindowState), form.WindowState);
windowState = key.GetValue("WindowState", windowState).ToString();
form.WindowState = (FormWindowState)Enum.Parse(typeof(FormWindowState), windowState);
}
}
}
}
catch
{
// Party on, Wayne!
}
}
}
Use this extension methods and call it on form shown, form Closing & form Move events
For Complete Working Sample
public partial class Form3 : Form
{
private int count = 1;
public Form3()
{
InitializeComponent();
}
private void Form2_Move(object sender, EventArgs e)
{
this.SaveFormSizeAndLocation();
}
protected override void OnShown(EventArgs e)
{
Text = Name;
base.OnShown(e);
this.LoadFormSizeAndLocation();
this.Move += Form2_Move;
}
protected override void OnFormClosing(FormClosingEventArgs e)
{
base.OnFormClosing(e);
this.SaveFormSizeAndLocation();
}
private void button1_Click(object sender, EventArgs e)
{
var frm = new Form3();
frm.Name = "inner" + count.ToString();
frm.Show();
count++;
}
}

C# - How to save a string entered in Form2 in Form1

I get the default path from the registry for the Steam installation. But if someone has their games installed to a different folder, the user has to enter it in the Configure form. When the form gets closed, that path entered(from the folder browser or by typing the path in manually) should get saved to a string in the main form and should enable a different Combobox which turns on different buttons. I somehow managed to do the save to the mainform string, but the 2nd combobox doesn't seem to turn on. How can I do it correctly?

Any help would be appriciated.
Look at your ConfigForm. Here's your problem:
public ConfigForm()
{
InitializeComponent();
Form1 frm1 = new Form1();
frm1.NewPath = NewPathBox.Text;
}
What you're doing on your Form1 (which I'm guessing is your Main form) is creating a new instance of your ConfigForm and showing it. What you're doing in your ConfigForm is creating a new main form and setting the NewPath = to the value entered on your config form. The problem is this new Form1 is NOT the Form1 that created the ConfigForm. The Form1 that created your config form is not the one getting updated by your code, some arbitrary new Form1 that you create is the one getting updated. This is why your code isn't working as you expected.
Here's the approach I would take. Add a NewPath variable to your ConfigForm just like you have in Form1. Then, add a FormClosing method to FormConfig. Do something like this:
private void ConfigForm_FormClosing(object sender, FormClosingEventArgs e)
{
NewPath = NewPathBox.Text;
}
Then, change your code on Form1 to this:
private void button1_Click(object sender, EventArgs e)
{
ConfigForm cfgfrm = new ConfigForm();
cfgfrm.ShowDialog();
this.NewPath = cfgfrm.NewPath;
}
What this code is doing is creating and showing a new ConfigForm on your Form1 when you click button1. Then, when your user closes the FormConfig, the form saves the textbox value to the NewPath variable on the FormConfig. Then, once the form is closed, the code on Form1 resumes. Form1 then looks at the NewPath value that was saved when the user closed the FormConfig. Form1 grabs this new NewPath value and puts it in its own NewPath variable.
EDIT
To show/hide comboboxes:
private void button1_Click(object sender, EventArgs e)
{
ConfigForm cfgfrm = new ConfigForm();
cfgfrm.ShowDialog();
this.NewPath = cfgfrm.NewPath;
Gamedropdown.Visible = false;
NewDropDown.Visible = true
}
I'm not sure why you are making the secondary form so complicated. You don't need a pointer to it after you use it and you should be closing instead of hiding. Try this:
class ConfigForm : Form
{
public string newPath = null;
public void CloseButton_Click(object sender, EventArgs e)
{
newPath = NewPathBox.Text;
}
public void CloseButton_Click(object sender, EventArgs e)
{
Close();
}
}
...and in your main form:
public partial class Form1 : Form
{
string steamPath = null; // set to starting path
private void ConfigureButton_Click(object sender, EventArgs e)
{
bool valueChanged = false;
using (ConfigForm form = new ConfigForm())
{
form.newPath = null;
form.ShowDialog();
if (form.newPath != null)
{
steamPath = form.newPath;
valueChanged = true;
}
}
if (valueChanged)
{
// here is where you would handle reloading and changing the ComboBoxes
}
}
}
This will more cleanly return the new string. Whatever you want to do as a result of having changed the path can be done after you have disposed of the config form (bringing it up with the "using" conditional automatically does the disposal for you)

Button with image and not visible text properties

Can I create a button with both .Image and .Text properties simultaniously, in such way, that text is not visible on form, and is created just for identifying what button should do at the moment?
Using TextAlign and TextImageRelation properties doesn't help. Text is always visible, just a position changes.
private System.Windows.Forms.Button bRenameCourse;
this.bRenameCourse.BackColor = System.Drawing.SystemColors.ButtonFace;
this.bRenameCourse.Image = ((System.Drawing.Image)(resources.GetObject("bRenameCourse.Image")));
this.bRenameCourse.Location = new System.Drawing.Point(966, 6);
this.bRenameCourse.Name = "bRenameCourse";
I want this text "Rename" to be not visible on button
this.bRenameCourse.Text = "Rename";
this.bRenameCourse.Size = new System.Drawing.Size(64, 60);
this.bRenameCourse.TabIndex = 10;
this.bRenameCourse.UseVisualStyleBackColor = false;
this.bRenameCourse.Click += new System.EventHandler(this.bRenameCourse_Click);
Here is why do I want it works :
private void bRenameCourse_Click(object sender, EventArgs e)
{
if (bRenameCourse.Text.Equals("Rename"))
{
//DO SMTHNG
bRenameCourse.Text = "OK";
}
else if (bRenameCourse.Text.Equals("OK"))
{
//DO SMTHNG
bRenameCourse.Text = "Rename";
}
}
I can avoid this using some flags, but I'd like to know if it's possible in general.
Don't use the .Text property of the button to store information.You can use the .Tag property
ie
this.bRenameCourse.Tag = "Rename";
And in the Event
private void bRenameCourse_Click(object sender, EventArgs e)
{
if (bRenameCourse.Tag.Equals("Rename"))
{
//DO SMTHNG
bRenameCourse.Tag = "OK";
}
else if (bRenameCourse.Tag.Equals("OK"))
{
//DO SMTHNG
bRenameCourse.Tag = "Rename";
}
}
Just set the .Text property to ""(blank or empty)

Why label2.Text in Form1 is not updating from the new class?

In Form1 i have label2 in the designer and i added a code:
public void lbl2(string text)
{
label2.Text = text;
}
In the new class top i added:
private static AnimationEditor.Form1 fr1 = new AnimationEditor.Form1();
And in the new class event im updating the label2.Text like this:
int ISampleGrabberCB.BufferCB(double sampleTime, IntPtr pBuffer, int bufferLen)
{
using (var bitmap = new Bitmap(_width, _height, _width * 3, PixelFormat.Format24bppRgb, pBuffer))
{
bitmap.RotateFlip(RotateFlipType.Rotate180FlipX);
if (SaveToDisc)
{
String tempFile = _outFolder + _frameId + ".bmp";
if (File.Exists(tempFile))
{
fr1.lbl2(_frameId.ToString();
}
else
{
bitmap.Save(Path.Combine(_outFolder, _frameId + ".bmp"));
}
_frameId++;
}
else
{
if (Images == null)
Images = new List<Bitmap>();
Images.Add((Bitmap)bitmap.Clone());
}
}
return 0;
}
Thel ine that is doing the updating is:
fr1.lbl2(_frameId.ToString();
Now i used breakpoint on this line in the new class and also in Form1 on the label2.Text in the public function and i saw that the label2 text is changing first its 0 then 1 then 2 and so on.
But in fact in realtime when im running the application the label2 dosent change its all the time the text saty as label2
This is the Form1 button click event when i click on it its doing the new class code:
private void button5_Click(object sender, EventArgs e)
{
wmv = new Polkan.DataSource.WmvAdapter(#"d:\VIDEO0040.3gp", sf);
wmv.SaveToDisc = true;
wmv.Start();
wmv.WaitUntilDone();
}
I think the quick answer is to pass in the reference of the label to the class:
private Label lbl;
public WmvAdapter(string file, string outFolder, Label label) {
// yada-yada-yada
lbl = label;
}
Your routine would change to:
if (File.Exists(tempFile))
{
lbl.Text = _frameId.ToString();
}
Your click event:
private void button5_Click(object sender, EventArgs e)
{
wmv = new Polkan.DataSource.WmvAdapter(#"d:\VIDEO0040.3gp", sf, this.Label2);
wmv.SaveToDisc = true;
wmv.Start();
wmv.WaitUntilDone();
}
The longer answer is to have your class raise an event and have your form listen for it.
Having your class be aware of the form is not the best coding practice.
