    VK_ESCAPE Problem

    Hi

    i have an application that creates a new window when the user presses a button. when the user wants to come out of the fullscrenn they press the ESCAPE key and this changes the window back to its orgional state.

    also this ESCAPE key needs to exit the application IF its not in fullscreen mode.

    The problem i have is when the user is in fullscreen and presses ESCAPE it exits the application. or if i dont have the second part it will just exit full screen

    here is the code i am using

    Code:
    if(Key == VK_ESCAPE) // if the user presses the ESCAPE key
    {
     imgImage->Height = ScreenHeight;
     imgImage->Width = ScreenWidth;
     imgImage->Stretch = true;
    
     Form1->BorderStyle = bsToolWindow;
     Form1->Height = 754;
     Form1->Width = 1070;
     Form1->Left = 190;
     Form1->Top = 115;
    
     Panel1->Visible = true;
     Label1->Visible = true;
     Prop->Visible = true;
     Stretch->Visible = true;
     ProgressBar1->Visible = true;
     StatusBar1->Visible = true;
     spOpen->Visible = true;
     spSave->Visible = true;
    
     if(Key == VK_ESCAPE)
     {
     Application->Terminate();
     }
     }
    Can anyone help?

    Recheck your logic:
    Code:
    if(Key == VK_ESCAPE) // if the user presses the ESCAPE key
    {
      if(Key == VK_ESCAPE)
       {
        //will always terminate
       Application->Terminate();
       }
    }
    Alternatively, perhaps you should consider using a different key for a different action? ESC for quitting is a good choice; try using one of the function keys for your display switching.

    Like Ken is trying to point out, your second IF statment will return the same as your first, so it's like not even being there.

    Try somthing more like:
    Code:
    if(Key == VK_ESCAPE) // if the user presses the ESCAPE key
    {
     if(bFullscreen)
     {
      bFullscreen = FALSE;
    
      imgImage->Height = ScreenHeight;
      imgImage->Width = ScreenWidth;
      imgImage->Stretch = true;
    
      Form1->BorderStyle = bsToolWindow;
      Form1->Height = 754;
      Form1->Width = 1070;
      Form1->Left = 190;
      Form1->Top = 115;
    
      Panel1->Visible = true;
      Label1->Visible = true;
      Prop->Visible = true;
      Stretch->Visible = true;
      ProgressBar1->Visible = true;
      StatusBar1->Visible = true;
      spOpen->Visible = true;
      spSave->Visible = true;
     }
     else
     {
       Application->Terminate();
     }
    }
    Of course, you need to set bFullscreen to TRUE when the user goes fullscreen.
