Using the SetDlgItemText function

[nima_ranjbar]

This is very basic but not for a beginner.

While developing a win32 application:
There is an edit box on a dialog box. Want the edit box to show a text when
the dialog box is being created.

case WM_INITDIALOG:
SetDlgItemText(hdwnd,ID_ESCREEN,"Here is the text");

There is no error while compiling. But when executing the app, I recieve a windows mwssage:
MyCalculator has caused an error in imekernel32.sys.

What am I missing here? Any hints?

Thanx In Advance

Strange, should work....
Are you sure thats the handle to the dialog?
And might there be something wrong with the way you make the editbox (unlikely)

Anyone that knows what the imkernel32 thing is?

[nima_ranjbar]

Yes, is really strange.
But the most confusing partis that I can initialize the edit box properly in another message such as WM_COMMAND.
I use VC++ and this is not the first headache I have with the compiler.

Is the dialog modal or modeless...?

I use VC and I dont have any problems.....load the following and say if it works

TEST.cpp

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

int CALLBACK WindowProc(HWND hwnd, 
UINT message,	WPARAM wParam, LPARAM lParam)
{
    switch (message)                
    {
           case WM_INITDIALOG:            
	SetDlgItemText(hwnd,IDC_EDIT1,"Here is the text");
           return 1;
           
		   case WM_COMMAND:

			   switch(wParam){
			   case IDOK:
				   EndDialog(hwnd,0);
			   }
			   return 1;         
    }
    return 0;
}



int WINAPI WinMain(HINSTANCE hThisInstance,
 HINSTANCE hPrevInstance,
 LPSTR lpszArgument, int nFunsterStil)

{
   return DialogBox(hThisInstance,
MAKEINTRESOURCE(IDD_DIALOG1),
HWND_DESKTOP,(DLGPROC)WindowProc);
