I need to combine a switch with an if-statement.
How can I do that? I want to do something like this:
switch (periodtype)
{
if(starttime>endtime)
{
;
}
else
{
case 0: nextRunTime = nextRunTime.AddHours(period); break;
case 1: nextRunTime = nextRunTime.AddMinutes(period); break;
case 2: nextRunTime = nextRunTime.AddSeconds(period); break;
}
}
What's wrong with:
if(starttime<=endtime)
{
switch (periodtype)
{
case 0: nextRunTime = nextRunTime.AddHours(period); break;
case 1: nextRunTime = nextRunTime.AddMinutes(period); break;
case 2: nextRunTime = nextRunTime.AddSeconds(period); break;
}
}
if(starttime>endtime)
{
// Stuff
}
else
{
switch (periodtype)
{
case 0: nextRunTime = nextRunTime.AddHours(period); break;
case 1: nextRunTime = nextRunTime.AddMinutes(period); break
case 2: nextRunTime = nextRunTime.AddSeconds(period); break;
}
}
Like that?
if(starttime>endtime)
{
;
}
else
{
switch (periodtype)
{
case 0: nextRunTime = nextRunTime.AddHours(period); break;
case 1: nextRunTime = nextRunTime.AddMinutes(period); break;
case 2: nextRunTime = nextRunTime.AddSeconds(period); break;
}
}
if(starttime <= endtime)
{
switch (periodtype)
{
case 0: nextRunTime = nextRunTime.AddHours(period); break;
case 1: nextRunTime = nextRunTime.AddMinutes(period); break;
case 2: nextRunTime = nextRunTime.AddSeconds(period); break;
}
}
Hmm way too late with answer
isnt this easier:
if (starttime <= endtime)
{
switch (periodtype)
{
case 0: nextRunTime = nextRunTime.AddHours(period); break;
case 1: nextRunTime = nextRunTime.AddMinutes(period); break;
case 2: nextRunTime = nextRunTime.AddSeconds(period); break;
}
}

I can load a picture to a UImageView with I click a button, but not from a timer. why is that ? and how can I fix it ?

I used the debugger, so I know the code is getting to the line
but it is not doing anything when it get there
the bebugger says:
UIKit.UIKitThreadAccessException: UIKit Consistency error: you are calling a UIKit method that can only be invoke from the UI Thread.
Is there a why around that ?
Any operation you involve in modifying UI view, you will need to do it under UI/Main thread. So put the code inside the lambda of:
InvokeOnMainThread ( () => {
// manipulate UI controls
});

I tried to keep your structure in tact, there are a few things that could be done in less characters and in less complicated ways, but as you are learning the language practice is the only thing that can improve your skills :) So well done.

break;
}
}
foreach (char eachChar in encodeArray) {
upperEncodedMsg += eachChar;
}
}
public void upperEncoded()
{
if (upperEncodedMsg != null)
{ upperEncodedMsg = upperEncodedMsg.ToUpper(); }
}
private void clearBtn_Click(object sender, EventArgs e)
{
messageTxt.Text = string.Empty;
msgLabel.Text = string.Empty;
processedMessageLabel.Text = "Processed Message: ";

private void encodeBtn_Click(object sender, EventArgs e)

{

I'd go down the route of creating a mapping using a Dictionary<char, char>(see here for details on Dictionary) and simply lookup the key value in the dictionary for each char in encodeArray. It may also be better to use a StringBuilder rather than just a string to store your encoded message.
Create Mapping
//Add Dictionary at the top of the class along with upperEncodedMsg string.
private Dictionary<char, char> charMapping;
private StringBuilder upperEncodedMsg;
//Create mappings. Use uppercase values here and you won't need to use your 'upperEncoded' method. This bit can be done in your Form1 constructor.
public Form1()
{
InitializeComponent();
charMapping = new Dictionary<char, char>();
charMapping.Add('A', 'T');
charMapping.Add('B', 'U');
//more mappings...
}
You can then remove the big switch statement you have and replace it with the following:
public void Encode()
{
upperEncodedMsg = new StringBuilder();
string message = Convert.ToString(messageTxt.Text);
char[] encodeArray = message.ToUpper().ToCharArray();
for(int i = 0; i < encodeArray.Length; i++)
{
//Use the mappings created earlier to get the associated char.
char outputLetter;
charMapping.TryGetValue(encodeArray[i], out outputLetter);
//Append letter to your upperEncodedMsg StringBuilder.
upperEncodedMsg.Append(outputLetter);
}
}
In your button click, at the bottom you can then add:
private void encodeBtn_Click(object sender, EventArgs e)
{
//your code...
msgLabel.Text = upperEncodedMsg.ToString();
}
The main benefit of doing it this way is that your mappings can be made available in other parts of your code. It also makes it easier to maintain and your mappings are loaded as soon as the form is, rather than waiting to call your encode method. A lookup of a Dictionary is also likely to be quicker than a large switch statement.
Actually this post is different from this (posted by me as well). I've a phone keypad in my UI and now I'm able to show the button is pressed when its corresponding key is down.

The problem is when hash key (Shift + 3) or star key (Shift + 8) is down, the '3' button (for case hash key) also be pressed in UI. How can I show that only hash button is pressed on UI when Shift + 3 are down, but not hash button together with '3' button?
Check the KeyEventArgs.Modifiers property, and only handle the key-down when no modifiers are set.
Alternatively, use the TextInput or PreviewTextInput event to get the composed text instead of the actual key. This may be preferable anyway, as it will respond to any method of entering the appropriate text input, rather than relying on a specific key (for example, you won't have to have cases for all the possible keys, such as the top-row numeric keys and the numeric pad keys, as you are now).
This works for me:
//Make the button to have "pressed" feel when the corresponding key is pressed

I am trying to create a program where the application should never exit until I press option '6'. Below is my sample program: Right now, if I press any option, it executes the corresponding method and console window closes (exits the application) after it is done executing. I want the console to wait for the next option to be entered.
Console.WriteLine(#"Select one of the following option:
1-Write Apps
2-Write Drivers
3-Write OS
4-Write Packages
5-All the above
6-Exit");
string strReadKey = Console.ReadKey().KeyChar.ToString();
int.TryParse(strReadKey, out selectionKey);
switch (selectionKey)
{
case 1:
DoApps(reqObj);
return;
case 2:
DoDrivers(reqObj);
return;
case 3:
DoOS(reqObj);
return;
case 4:
DoPackages(reqObj);
return;
case 5:
DoAll(reqObj);
return;
case 6:
Environment.Exit(0);
return;
default:
DoAll(reqObj);
return;
}
You can just place your code into a loop, and change the return to break statements:
while(true) // Loop forever
{
string strReadKey = Console.ReadKey().KeyChar.ToString();
int.TryParse(strReadKey, out selectionKey);
switch (selectionKey)
{
case 1:
DoApps(reqObj);
break; // Break, don't return
case 2:
DoDrivers(reqObj);
break;
case 3:
DoOS(reqObj);
break;
case 4:
DoPackages(reqObj);
break;
case 5:
DoAll(reqObj);
break;
case 6:
Environment.Exit(0);
break;
default:
DoAll(reqObj);
break;
}
}
If you wish to prompt for input each iteration, you can move the prompt into the loop, as well.
using System;
namespace LoopUntilSelectionTester
{
class Program
{
static void Main()
{
string key;
while((key = Console.ReadKey().KeyChar.ToString()) != "6")
{
int keyValue;
int.TryParse(key, out keyValue);
ProcessInput(keyValue);
}
}

DoAll(reqObj);
break;
}
}
}
}
First, what I'd do is make it into a method:
public void AskForInput()
{
Console.WriteLine(#"Select one of the following options:
1-Write Apps
2-Write Drivers
3-Write OS
4-Write Packages
5-All the above
6-Exit");
string strReadKey = Console.ReadKey().KeyChar.ToString();
int.TryParse(strReadKey, out selectionKey);
switch (selectionKey)
{
case 1:
DoApps(reqObj);
return;
case 2:
DoDrivers(reqObj);
return;
case 3:
DoOS(reqObj);
return;
case 4:
DoPackages(reqObj);
return;
case 5:
DoAll(reqObj);
return;
case 6:
Environment.Exit(0);
return;
default:
DoAll(reqObj);
return;
}
}
and then just use it like this:
for (;;) AskForInput();
Just wrap the whole thing in a while statement.
while (true)
{
Console.WriteLine(#"Select one of the following option:
1-Write Apps
2-Write Drivers
3-Write OS
4-Write Packages
5-All the above
6-Exit");
string strReadKey = Console.ReadKey().KeyChar.ToString();
int.TryParse(strReadKey, out selectionKey);
switch (selectionKey)
{
case 1:
DoApps(reqObj);
break;
case 2:
DoDrivers(reqObj);
break;
case 3:
DoOS(reqObj);
break;
case 4:
DoPackages(reqObj);
break;
case 5:
DoAll(reqObj);
break;
case 6:
Environment.Exit(0);
break;
default:
DoAll(reqObj);
break;
}
}
This worked for me:
Console.WriteLine(#"Select one of the following option:
1-Write Applications XML
2-Write Drivers XML
3-Write Operating Systems XML
4-Write Packages XML
5-All the above
6-Exit");
string strReadKey = Console.ReadKey().KeyChar.ToString();
int.TryParse(strReadKey, out selectionKey);
while (true)
{
switch (selectionKey)
{
case 1:
DoApplications(reqObj);
strReadKey = Console.ReadKey().KeyChar.ToString();
int.TryParse(strReadKey, out selectionKey);
break;
case 2:
DoDrivers(reqObj);
strReadKey = Console.ReadKey().KeyChar.ToString();
int.TryParse(strReadKey, out selectionKey);
break;
case 3:
DoOperatingSystems(reqObj);
strReadKey = Console.ReadKey().KeyChar.ToString();
int.TryParse(strReadKey, out selectionKey);
break;
case 4:
DoPackages(reqObj);
strReadKey = Console.ReadKey().KeyChar.ToString();
int.TryParse(strReadKey, out selectionKey);
break;
case 5:
DoAll(reqObj);
strReadKey = Console.ReadKey().KeyChar.ToString();
int.TryParse(strReadKey, out selectionKey);
break;
case 6:
Environment.Exit(0);
break;
default:
DoAll(reqObj);
strReadKey = Console.ReadKey().KeyChar.ToString();
int.TryParse(strReadKey, out selectionKey);
break;
}
}
I have the following stored procedure that I have to get data from:
EXECUTE [dbo].[StationHealthStatusSummary2]
#LineId varchar(100), // 5,9,10
#MeasurementDt datetime, //2012/06/06
#Ntotal Int output,
#N0 int output,
#N1 int output,
#N2 int output,
#N3 int output,
#N4 int output,
#N5 int output,
#N6 int output,
#N7 int output,
#N8 int output,
#N9 int output,
#N10 int output,
#N11 int output,
#N12 int output,
#N13 int output,
#N14 int output,
#N15 int output,
#N16 int output
GO
Now I can send parameters to LineID and Measurement date as follows:
SqlConnection sql = new SqlConnection(#"Data Source=(local)\SQLEXPRESS;Initial Catalog=iComs;Persist Security Info=True;User ID=sa;Password=Password);
SqlCommand getData = new SqlCommand("StationHealthStatusSummary2", sql);
SqlDataAdapter da = new SqlDataAdapter(getData);
getData.CommandType = CommandType.StoredProcedure;
getData.Parameters.Add(new SqlParameter("#LineId", Lines));
getData.Parameters.Add(new SqlParameter("#MeasurementDt", date1));
SqlParameter ParamaterNtotal = new SqlParameter();
ParamaterNtotal.ParameterName = "#Ntotal";
ParamaterNtotal.SqlDbType = SqlDbType.Int;
ParamaterNtotal.Direction = ParameterDirection.Output;
getData.Parameters.Add(ParamaterNtotal);
sql.Open();
getData.ExecuteNonQuery();
Now I can get the value of NTotal and assign it to a Teechart (PieSlice),
but how do I get the value for #N0..#N16?
I've got some code that might give you some idea of what I'm trying to accomplish.
int NTotal = int.Parse(getData.Parameters["#Ntotal"].Value.ToString());
if (GetVariantVariableI(getData.Parameters[0].Value) = 0)
{
for (c = 1; c <= 18; c++)
{
Nvl = GetVariantVariableI(getData.Parameters[2+c].Value);
switch(c)
{
case 1:
NTotal = Nvl;
break;

case 14:
case 15:
case 16:
case 17:
case 18:
case 19:
case 20:
cstatus = c-2;
NPieValues[cstatus] = Nvl;
break;
}
string SliceName;
int NUsed;
NUsed = 0;
for(i=0;i<=16;i++)
{
NUsed = NUsed + NPieValues[i];
}
if (NUsed < NTotal)
{
Chart1.Series[0].Add(NTotal - NUsed);
slice1.Title = "Not Connected";
slice1.Add();
slice1.Color = System.Drawing.Color.Silver;
}
if (NUsed > NTotal)
{
NPieValues[7] = NPieValues[7]-(NUsed-NTotal);
}
for (i=0;i<=16;i++)
{
if (NPieValues[i]>0)
{
switch(i)
{
case 0: SliceName ="Green";
break;
case 1: SliceName ="Yellow";
break;
case 2: SliceName ="Orange";
break;
case 3: SliceName ="Red";
break;
case 4: SliceName ="Broken Rail";
break;
case 5: SliceName ="Buckling Rail";
break;
case 6: SliceName ="Maintenance required";
break;
case 7: SliceName ="Station(s) Off";
break;
case 8: SliceName ="Rail Differential kN";
break;
case 9: SliceName ="Left Rail Sensor Faulty";

case 10: SliceName ="Right Rail Sensor Faulty";

}
switch(i)
{
case 0: clr = "System.Drawing.Color.Green";
break;
case 1:clr = "System.Drawing.Color.Yellow";
break;
case 2:clr = "System.Drawing.Color.Orrange";
break;
case 3:clr = "System.Drawing.Color.Red";
break;
case 4:
case 5:
case 8:clr = "System.Drawing.Color.Purple";
break;
case 6:clr = "System.Drawing.Color.Black";
break;
case 7:clr = "System.Drawing.Color.Gray";
break;;
case 9:clr = "System.Drawing.ColorTranslator.FromHtml('#E0671F')";
break;
case 10:clr = "System.Drawing.ColorTranslator.FromHtml('#BA4EC2')";
break;
case 11:clr = "System.Drawing.ColorTranslator.FromHtml('#FF8000')";
break;
case 12:clr = "System.Drawing.ColorTranslator.FromHtml('#BF4093')";
break;
case 13:clr = "System.Drawing.Color.SkyBlue";
break;
case 14:clr = "System.Drawing.Color.Aqua";
break;
case 15:clr = "System.Drawing.ColorTranslator.FromHtml('#BFBFFF')";
break;
case 16:clr = "System.Drawing.Color.MedGray";
break;
default : clr = "System.Drawing.Color.White";
break;
}
slice1.Add(NPieValues[i],SliceName,clr);
}
}
}
}
}
Now after it got all those values it has to populate the piechart.
Please, any help will be highly appreciated and please tell me if I'm being too vague.
Thanks
You have added #Ntotal as an Output parameter, why didn't you add all the others?
SqlParameter n = new SqlParameter();
n.ParameterName = "#N0";
n.SqlDbType = SqlDbType.Int;
n.Direction = ParameterDirection.Output;
getData.Parameters.Add(n);
Then you can retrieve the output values the same way you do with #Ntotal. Also, you can retrieve the values by name instead of looping through them, if you prefer.
Thanks. I Figured it out...
after i send the parameters as follows:
SqlParameter Paramater0 = new SqlParameter();
Paramater0.ParameterName = "#N0";
Paramater0.SqlDbType = SqlDbType.Int;
Paramater0.Direction = ParameterDirection.Output;
getData.Parameters.Add(Paramater0);
I then get the value and declare it to a var as follows:
int N0 = int.Parse(getData.Parameters["#N0"].Value.ToString());
and finally declare that int to a slice on the chart as follows:
slice1.Add(N0, "Green", System.Drawing.Color.Green);
Thanks for your help #mgnoonan :)
