Thread: Dialog

Hi,

I need help in writing a simple Windows application. I'm just starting out with Win32 so I'm having a lot of problems with this.

I want an application that would only have one dialog box - no window. I already know how to write an application with a window, but I don't what to do with the dialog box - how to create it.

I don't want to post my code just yet, becuase it's a complete mess, but I also don't expect anyone to write me the whole code. I think I can figure most of it out if you give me some pointers. I don't even know how to show the dialog - with the CreateWindow/ShowWindow function? Do I need the wndclass when dealing with only a dialog?

As I said, I'm just starting but I can write a simple window so I'd just need some guides where to go.


btw, while trying to figure out this myself I was able to create a windows application that compiled but didn't run. There wasn't anything odd in the code, yet whenever I ran it, it didn't show up (couldn't see it in task manager either).

Dialog Box tutorial

Thanks about that, but I'm having a problem.

I did exactly like written in that tutorial and it worked OK. Then I opened the resource file to edit some code and renamed IDD_DIALOG1 to IDD_DLG etc... And now when I build it, I can't run the exe. This has happened before (as I wrote in my first post) and I don't know what's happening. The project compiles without errors etc... basically the program exists and should be working but for some reason I can't run it :|

I even tried this app at a friend and the same happens. As I said, this happened a couple of times already to me. I think manually editing the .rc files causes this?

Yes I did that, but the problem was still there. After some fiddling around I found out the problem was with the text editor control. I don't know why or what but whenever I add a control to the dialog I can't run the executable (but it compiles).

Can anyone please download this project and test themselvec why this is happening? Maybe I'm missing something.

In the download you provided, I can't find any EDIT controls anywhere.

Yeah, sorry about that. I forgot to write that you should try compiling it the way it is and run it. Then try adding an edit control, recompile it and see if it runs.

After adding an edit control, I had to change

Code:

	case WM_COMMAND:
		switch(wParam)
		{
		case IDCLOSE:
			EndDialog(hWndDlg, 0);
			return TRUE;
		}

to this

Code:

  case WM_COMMAND: {
    switch(wParam) {
      case IDCLOSE: {
        EndDialog(hWndDlg, 0);
        return TRUE;
      }
    }
    return TRUE ;
  }

Then the edit control displays.

Thanks everyone. I'm still learning and I need to get this done fast for school
Althought, Dante, your solution did work, I think the problem was that I used a common control, so I had to include commctrl.h, ComCtl32.lib and call InitCommonControls().

I have another question.

So I made an edit control but I want it to only accept numbers from 0 to 50 - I used ES_NUMBER flag for only numbers - but I don't know how to either prevent typing in any larger number or attach a spin control to the edit box and then set the spin range to 0-50.

The major problem I'm having is how to attach the spin control to the edit control. I tried grouping, buddying,... Also I would like to keep it as win32 as possible (AFAIK spin control is MFC) so if anyone can tell me how to do this with the Win32 up-down control?

Thanks again.
