I try to open System file dialog to select a pic. the code ran normally in my computer. But in another computer cant show the system file dialog.
And here is my simple code:-
private void PicInputBtn_Click(object sender, RoutedEventArgs e)
{
var dialog = new Microsoft.Win32.OpenFileDialog
{
DefaultExt = ".jpg",
Filter = "img file|*.jpg",
};
if (dialog.ShowDialog() != true)
{
return;
}
｝
If nothing happens but the mouse pointer turning into a little busy-indicator.
You can try to set your thread to STAThread:
[STAThread]
static void Main(string[] args)
{
var o = new OpenFileDialog();
var r = o .ShowDialog();
}
Howover they are many reasons that can break the OpenFileDialog, you can try to launch your program in admin mode and try to reinstall .net Framework
Change your code to:
private void PicInputBtn_Click(object sender, RoutedEventArgs e)
{
var dialog = new Microsoft.Win32.OpenFileDialog
{
DefaultExt = ".jpg",
Filter = "img file|*.jpg" // You had an extra ',' here.
};
if ((Nullable<bool>dialog.ShowDialog()) == true) // Also you forgot to put Nullable<bool>
{
// string filename = dlg.FileName;
}
else
{
return;
}
｝

I'm been wondering is there a way to save a file in specific's folder in C#?
The only method that I know is 'SaveFileDialog' but the problems is I want to save files
in folder without showing saveFilesDialog's Box.
saveFilesDialog's Box : is a box that prompts you to Click 'YES' or 'CANCEL'.
Code samples
-In form1
public Form1()
{
InitializeComponent();
}
private string Path =#"D:\Files"; //locaction i wanna stores all the files in
private int i = 0;
private button1_Click(object sender,EventArgs e)
{
i++;
SaveDialogFile save = new SaveDialogFile();
if(Save.
if (save.ShowDialog() != DialogResult.OK)return; //Prompt's Dialog will show
save.Filter = "File Text(*.txt)|*.txt";
save.InitialDirectory = Path;
save.FileName = "txt"+i.ToString();
//Goal : i want 'save.FileName' store in 'Path' without Click 'OK' or Show Prompt Dialog's box
}
Expect Result

Anyone can help me? I kinda stuck rn :)
This is my full code it's hard to read but you'll get the point
public partial class convertMp3ToWav : Form
{
public convertMp3ToWav()
{
InitializeComponent();
}
BackgroundWorker bw;
string withoutEx;
List<string> song_lists = new List<string>();
private void button1_Click(object sender, EventArgs e)
{
bw = new BackgroundWorker();
bw.DoWork += (obj, ae) => newThread();
bw.RunWorkerAsync();
}
void newThread()
{
Thread th = new Thread
((ThreadStart)(() =>
{
file();
}));
th.SetApartmentState(ApartmentState.STA);
th.Start();
th.Join();
}
void file()
{
string path = #"D:\musics\wav";
Directory.CreateDirectory(path);
FolderBrowserDialog f = new FolderBrowserDialog();
f.ShowDialog();
string[] lists = Directory.GetFiles(f.SelectedPath, "*.*", SearchOption.AllDirectories);
foreach (string list in lists)
{
if (Path.GetExtension(list) == ".mp3")
{
string fn = Path.GetFullPath(list);
withoutEx = Path.GetFileNameWithoutExtension(fn);
song_lists.Add(fn);
Console.WriteLine(withoutEx);
SaveFileDialog save = new SaveFileDialog();
save.Filter = "Wav FIle (*.wav)|*.wav;";
//save.FileName = song_lists[0];
save.FileName = withoutEx;
save.InitialDirectory = path;
if (save.ShowDialog() == DialogResult.OK)
{
using (Mp3FileReader mp3 = new Mp3FileReader(fn))
{
using (WaveStream pcm = WaveFormatConversionStream.CreatePcmStream(mp3))
{
WaveFileWriter.CreateWaveFile(save.FileName, pcm);
}
}
}
}
}
}
}
this code's work pretty well!! but i need to click 'OK' everytime!!
so is there anyway to save file without click 'OK' everytime!!
Conceptually the only thing SaveFileDialog is doing, if you merely click OK when it shows, is changing the file extension*. Use Path.ChangeExtension instead
var pathToSaveWavTo = Path.ChangeExtension(pathToMp3, "wav");
The wav will be saved alongside the mp3. If you want to save it elsewhere, use Path.Combine to build a new path e.g.
pathToSaveWavTo = Path.Combine(#"c:\temp", Path.GetFileName(pathToSaveWavTo));
*I say this because giving it a filter of *.WAV and a filename xxx without the mp3 extension will cause it to give you a filename of xxx.wav when you only click OK, thus xxx.mp3 -> xxx.wav
i'm stuck with my program in c#. So the user has to press a button to create a random string (working fine) he can then chose to click on the other button. this one opens a filedialog and let him chose a dll file he want to rename into the random string. i can't get it working. it says my dll is already running in another process (wich is not). Any help is greatly appreciated :)
private void btnEncrypt_Click_1(object sender, EventArgs e)
{
// sets a random string to txtEncrypt.text
}
private void button1_Click(object sender, EventArgs e)
{
OpenFileDialog MyOpenFileDialog = new OpenFileDialog();
//filedialog
MyOpenFileDialog.Filter = "dll files (*.dll) |*.dll";//filter
MyOpenFileDialog.Title = "Chose the dll file";
MyOpenFileDialog.InitialDirectory = "C:\\Users\\Gebruiker\\Desktop";
MyOpenFileDialog.FilterIndex = 1;
MyOpenFileDialog.RestoreDirectory = true;
//if ok
if (MyOpenFileDialog.ShowDialog() == DialogResult.OK)
{
strPath = MyOpenFileDialog.FileName;
StreamReader reader = new StreamReader(strPath);
System.IO.File.Move(strPath, "C:\\Users\\Gebruiker\\Desktop\\" + txtEncrypt.Text + ".dll");
}
else //cancel
{
strPath = null;
}
It's because your StreamReader is opening the file so it can't be moved. That line doesn't appear to be doing anything anyway so you can probably remove it. Ideally replace it with
if (System.IO.File.Exists(strPath))
{
System.IO.File.Move(strPath, "C:\\Users\\Gebruiker\\Desktop\\" + txtEncrypt.Text + ".dll");
}
Just comment the initialization of the streem reader line or move it next to the rename line but don't forget to pass the new name

Hello Stackoverflow-Community,
So i've tried to be able to start the selected File(from the Listbox) by clicking the Start button.The items in the Listbox are loaded in from a .txt-File, But it seems that the path that i get (from the .txt-File) is not actually the same that was written inside.
For example: H:\Exe\556689600.exe is written inside the .txt-File but when i check while pausing the application the value of the SelectedItem is "H:(two backslashes)Exe(two backslashes)556689600.exe" so i'd like it to be H:\Exe\556689600.exe so it can be properly started.
EDIT: The main problem is that i can't start the .exe that i selected (via cmdStart) and i don't know why.
Please keep in mind that i'm (as you can see from the code) not very experienced in programming and that i'm not an native english speaker, so pardon me for any grammatical mistakes/logic mistakes made.
Thanks in advance,
Stephen
The problem is with:
DialogResult Ergebnis2 = MessageBox.Show("Would you like to start the Game right now?", "Game start?", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
if (Ergebnis2.Equals(true))
DialogResult holds the Enum data 'DialogResult.Yes', so you need to compare it to that value, and not (true).
Edit:
I suggest practicing working with debug:
In this case, I plated a breakpoint on the 'cmdstart_Click' method and followed it step by step (Used F10)
I saw that we jump over the 'if' condition, and checked why.
My issue is that I keep seeing a recurring theme with trying to allow my Notepad clone to save a file. Whenever I try to save a file, regardless of the location on the hard disk, the UnauthorizedAccess Exception continues to be thrown. Below is my sample code for what I've done, and I have tried researching this since last night to no avail. Any help would be greatly appreciated.
//located at base class level
private const string fileFilter = "Text Files|*.txt|All Files|*.*";
private string currentPath = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
private void MenuFileSaveAs_Click(object sender, RoutedEventArgs e)
{
SaveFileDialog sfd = new SaveFileDialog();
sfd.DefaultExt = "*.txt";
sfd.Filter = fileFilter;
sfd.AddExtension = true;
sfd.InitialDirectory = currentPath;
sfd.RestoreDirectory = true;
sfd.OverwritePrompt = true;
sfd.ShowDialog();
try
{
System.IO.File.WriteAllText(currentPath,TxtBox.Text,Encoding.UTF8);
}
catch (ArgumentException)
{
// Do nothing
}
catch(UnauthorizedAccessException)
{
MessageBox.Show("Access Denied");
}
}
Change the following lines.
...
if (sfd.ShowDialog() != true)
return;
try
{
using (var stream = sfd.OpenFile())
using (var writer = new StreamWriter(stream, Encoding.UTF8))
{
writer.Write(TxtBox.Text);
}
}
...
I hope it helps you.
You need to get the correct path context and file object from the dialog box once the user has hit 'ok'. Namely verify the user actually hit ok and then use the OpenFile property to see what their file selection is:
if (sfd.ShowDialog.HasValue && sfd.ShowDialog)
{
if (sfd.OpenFile() != null)
{
// convert your text to byte and .write()
sfd.OpenFile.Close();
}
}
I am having trouble calling the string "rlist" from:
public void main()
{
string rlist;
if (radioButton1.Checked)
textBox1.Enabled = false;
textBox1.ReadOnly = true;
rlist = "text";
}
to
public void button1_Click(object sender, EventArgs e)
{
OpenFileDialog openFile = new OpenFileDialog();
openFile.Filter = "WTF Files (*.wtf)|*.wtf";
openFile.Title = "Please Pick your realmlist file:";
if (openFile.ShowDialog() == DialogResult.Cancel)
return;
try
{
textBox5.Text = openFile.FileName;
string file = openFile.FileName;
TextWriter rlist_writer = new StreamWriter (openFile.FileName);
rlist_writer.WriteLine(rlist);
rlist_writer.Close();
}
catch (Exception)
{
MessageBox.Show("Error opening file", "File Error",
MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
}
}
I get the error on this line:
rlist_writer.WriteLine(rlist);
is it possible to call a string from one function and send it to the other with the same value it had in the function it was originally pulled from?
By the sounds of your question,
Your string is local to your main function.
So judging by your method names and knowledge of winforms(presumed again)
you need to make your string class level
string rlist;
public void main()
{
rlist = "yay"
public void button1_Click(object sender, EventArgs e)
{
someText = rlist;
As it currently stands you are not able to, as temporary (local) variables will be cleaned through garbage collection when you leave the method
Edit
You may wish to review this also
try
{
textBox5.Text = openFile.FileName;
using(TextWriter rlist_writer = new StreamWriter (openFile.FileName))
{
rlist_writer.WriteLine(rlist);
}
}
You can define that variable in your class scope, then if you call that variable in your button_click event, it will maintain the same value as in your main method.
