Suppose we have that part of code:

for(...)
{
  foreach(...)
  {
    if (...)
    {
      while(...)
      {
        <big>-> XXX <-</big>
      }
    }
  }
}

how am I supposed to exit from the place 'XXX' so that I would 'land' outside (after) the most internal ('for') loop?

One way would be to turn that code into it's own subroutine and use return; to break the process and close the subroutine

Use goto

for(...)
{  
  foreach(...)  
  {    
    if (...)    
    {      
      while(...)      
      {        
        //-> XXX <-
        goto Gotcha;
      }    
    }  
  }
}
Gotcha:
  Console.WriteLine("Gotcha");

this is surely fastest way but is recognazed as extremaly nasty... there is no other way (line using several break;`s ?)

You would have to rethink the logical program flow then.

Hi, I am using the system.drawing.printing.Printdocument in a small windows application to print labels. I am wondering if there is a way to prevent the printing progress dialog box from displaying once the user has initiated the print function?

Yes. Put this before your Print call:

myPrintDocument.PrintController = new StanderdPrintController();

I hope this helps! Smile | :)

The folder is wrong - it's 1033, at least on my PC it is. The rest of that path works fine on my computer.

First of all, any solution for creating an exe without the framework is a hack. Second, this product is obviously crap, because it's looking for a dll it needs in the wrong place. I'd give it up.

hi,
i read: If your .NET program uses new external Assemblies, you can use this option to automatically import any referenced assemblies..... -> no crap: http://thinstall.com/help/?linking_netframework.htm[^]

No chance in hell. I wouldn't trust any framework like that, like I said, it's a hack.

Global Hook on IR control

Hi, I used the tutor from microsoft to get messages from my IR Control (link). The code works fine, but when the window loses focus, it doesn't work anymore.
I need this code to work also when the program doesn't have focus (global hook?).

Thanks in advance.

From the little that I've seen about this, the remote works by using keyboard emulation. About half of the remote's keys are sent to the application using WM_INPUT and WM_KEYDOWN messages. This makes it easy to use, but when the focus changes, the "keystrokes" are now going to another application.

This presents a problem. Since the message from the remote are exactly like normal keyboard messages, there's no way to tell them apart. You COULD put together a low level keyboard hook, but there's no way to tell if the keystrokes you're seeing are coming from the real keyboard or from the remote.

How can I validate @ sign in KeyEventArgs?

I use following code snip to validate @ sign, but it works with US keyboard only.

switch(e.KeyData)
{
case Keys.D2 | Keys.Shift: // @

It seems that System.Windows.Forms.Keys enumeration did not specified @ sign. How can I know I receive @ sign in KeyEventArgs?

TIA,

Frank

Have you checked the integer value of the keycode? My guess is that value will be unique to the @ symbol.

The value is 50, which is the ASCII value of 2. The KeyData is Keys.D2 | Keys.Shift. Actually, the ASCII value of @ is 64. Any idea? TIA.

C# equivalent method or capturing keystrokes

Steve Messer6-Sep-05 11:11

Here is a quote from one of Nish's articles using MFC

Using PreTranslateMessage to handle dialog keystrokes
Very often you hear questions from novice programmers asking 
how they can trap keystrokes in a dialog based application. 
Presumably they tried to handle WM_KEYDOWN/WM_KEYUP unsuccessfully. 
The whole problem is that in a dialog based application the focus 
is always on one of the child controls and not on the main dialog 
window. So what do you need to do? You need to override 
PreTranslateMessage.

How do you accomplish this using C#?

Re: C# equivalent method or capturing keystrokes

Christian Graus6-Sep-05 11:32

There is a SystemKey event. Also, a dialog in C# has a property called 'key preview', which I believe means the dialog gets the keyboard message before the control does.
