GUI stuff

I'm trying to create a GUI for a simple program I'm working on. I figured out how to use resource dialogs (in VC++ 5). And making a GUI in that is sooo easy. Is it possible to use just this dialog for my program?

I can't seem to word this correctly. I guess what I want is a dialog with no parent.

Any help would be great. Thanks.

If you just want that dialog to show up when your program starts, then it's possible!

(I actually did not fully understand your question;))

Basically. The visible application would be just that dialog. I just dont want to do a bunch of "CreateWindows" to make everything.

Better?

You just need to call "CreateDialog" or "ShowDialog" to make the dialog visible.

Here is a simple dialog based app that just shows a dialogbox (stored in a resource file) when the program starts:

Code:

---

#include <windows.h>
#include "resource.h"
static HINSTANCE hinst = NULL;

BOOL CALLBACK DlgProc(HWND, UINT, WPARAM, LPARAM);

HWND dlghwnd;

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
  LPSTR lpCmdLine, int nCmdShow)
{
  WNDCLASSEX WndClass;
  MSG Msg;

  hinst = hInstance;

  dlghwnd = CreateDialog(hinst, MAKEINTRESOURCE(MYDLG), NULL, DlgProc);

  ShowWindow(dlghwnd, nCmdShow);
  UpdateWindow(dlghwnd);

  while(GetMessage(&Msg, NULL, 0, 0))
  {
      TranslateMessage(&Msg);
      DispatchMessage(&Msg);
  }
  return Msg.wParam;
}





BOOL  CALLBACK DlgProc(HWND hwnd, UINT Message, WPARAM wparam, LPARAM lparam)
{
       
  switch(Message)
  {
 
  case WM_INITDIALOG:

          return TRUE;


      case WM_CLOSE:
                  EndDialog(hwnd, 0);
        PostQuitMessage(0);

                return TRUE;
     
  }
  return FALSE;
}

Ok it compiles 0 errs 0 warns but when I run it there is no window. I check running processes and it IS there, so I kill it.

Heres my code:

Code:

---

#include <windows.h>
#include "resource.h"

HWND dlghwnd;

BOOL CALLBACK DlgProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam)
{
    return TRUE;
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
  MSG Msg;
  HINSTANCE hinst;
  hinst = hInstance;

  dlghwnd = CreateDialog(hinst, MAKEINTRESOURCE(ID_dialog_compviewer), NULL, (WNDENUMPROC)DlgProc);

  ShowWindow(dlghwnd, nCmdShow);
  UpdateWindow(dlghwnd);

  while(GetMessage(&Msg, NULL, 0, 0))
  {
      TranslateMessage(&Msg);
      DispatchMessage(&Msg);
  }
  return Msg.wParam;
}

What am I not doing? Thanks.

I just made a little changes to the code. See if that helps

Code:

---

#include <windows.h>
#include "resource.h"

HWND dlghwnd;

BOOL CALLBACK DlgProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam)
{
    switch(Message)
  {
 
  case WM_INITDIALOG:  //You need to handle this messages and return
                                                //TRUE for that

          return TRUE;


      case WM_CLOSE:  //If you want close the dialog box and exit the
                                        //program then you also need to handle this message
                  DestroyWindow(hwnd); //Closes the dialog box
        PostQuitMessage(0);  //Exit the program

                return TRUE;
     
  }
  return FALSE;  // Return FALSE for any other message that we dont
                                        //care of
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
  MSG Msg;
  HINSTANCE hinst;
  hinst = hInstance;

  dlghwnd = CreateDialog(hinst, MAKEINTRESOURCE(ID_dialog_compviewer), NULL, DlgProc); //You dont need "WNDENUMPROC" here

  ShowWindow(dlghwnd, nCmdShow);
  UpdateWindow(dlghwnd);

  while(GetMessage(&Msg, NULL, 0, 0))
  {
      TranslateMessage(&Msg);
      DispatchMessage(&Msg);
  }
  return Msg.wParam;
}

if I dont put the (WNDENUMPROC) in there I get this error:

error C2664: 'CreateDialogParamA' : cannot convert parameter 4 from 'int (void *,unsigned int,unsigned int,long)' to 'int (__stdcall *)(void)'

??

I get an error message when I use WNDENUMPROC in VC++. Just leave it where it is and then try to run your code :D

That example project works great! Thank you.
