The questions I''m posting are related to Windows Programming. 1) Assuming that in a dialog box, can I use these: TextOut(hdwnd,1,1,str,strlen(str)); Notes : The location is occupied by a check box. Attempt : When I did this, I get a runtime error message box Advise : What is the correct way(suitable for newbie) to implement Textout() in this case? The road may be long, wind may be rough. But with a will at heart, all shall begone. ~savage chant

Actually, sad to say that for my resource file, I am still hardcoding it and I''ve recently heard of a "Resource editor" where we may create resource file without doing much of the coding. But there''s something strange is that I have consulted my school lecturers regarding the issue and they tend to push me around the faculty like the "Tai-Chi fist" and end up getting no answer. Really regretted studying at that school.

Regarding the overlapping of CheckBox, It was a fault on my side as I did a wrong calculation of the location to drop the control and it was a painful lesson indeed. Driving me nuts for the past 2 days trying to rectify the prob.

I guess I will use static text control and try again. Tkx

I've tried to display my text in the CTEXT static control using SendDlgItemMessage() but it failed. I've even tried displaying it in messagebox, it fails again.

I think I'm stuck

      	case WM_TIMER:		if(counter == 0)		{			KillTimer(hdwnd,IDD_TIMER);			if(SendDlgItemMessage(hdwnd,IDD_CB2,BM_GETCHECK,0,0) == BST_CHECKED)			{				MessageBeep(MB_OK);			}			else			{				MessageBox(hdwnd,"BOOM!","Timer message",MB_OK);			}		}		else		{			counter--;			if(SendDlgItemMessage(hdwnd,IDD_CB1,BM_GETCHECK,0,0) == BST_CHECKED)			{				sprintf(str,"Number of seconds left before alert : %n",counter);				MessageBox(hdwnd,str,"Test",MB_OK);				//SetDlgItemText(hdwnd,IDD_CTEXT,str);			}		}		return 1;      

The error message is :
The instruction at "0x0040303f" referenced memory at
"0x00000001". The memory could not be "written".

NOTES : I'm using a modeless dialog box.
hdlg=CreateDialog(hInst,"MyDialog",hwnd,(DLGPROC)DialogFunc);

Below is my entire DialogFunc(), hope that may have some clues on what went wrong? At the mean time I''ll try if I have such probs with modal dialog...

Is it true that Modeless Dialog box is more restrictive compared to Modal Dialog box?

The "hdwnd" is actually the parameter for DialogFunc(), thus it should hold the handle of the Dialog Window right?

  BOOL CALLBACK DialogFunc(HWND hdwnd,UINT message,						 WPARAM wParam, LPARAM lParam){	static int counter;	switch(message)	{		case WM_COMMAND:		switch(LOWORD(wParam))		{		case IDD_START:			counter = vPos;			SetTimer(hdwnd,IDD_TIMER,1000,NULL);			if(SendDlgItemMessage(hdwnd,IDD_RB1,BM_GETCHECK,0,0) == BST_CHECKED)			{				ShowWindow(hwnd,SW_MAXIMIZE);			}			else			if(SendDlgItemMessage(hdwnd,IDD_RB2,BM_GETCHECK,0,0) == BST_CHECKED)			{				ShowWindow(hwnd,SW_MINIMIZE);			}			break;		case IDCANCEL:			DestroyWindow(hdlg);			break;		}//close inner switch		return 1;	case WM_TIMER:		if(counter == 0)		{			KillTimer(hdwnd,IDD_TIMER);			if(SendDlgItemMessage(hdwnd,IDD_CB2,BM_GETCHECK,0,0) == BST_CHECKED)			{				MessageBeep(MB_OK);			}			else			{				MessageBox(hdwnd,"BOOM!","Timer message",MB_OK);			}		}		else		{			counter--;			if(SendDlgItemMessage(hdwnd,IDD_CB1,BM_GETCHECK,0,0) == BST_CHECKED)			{								sprintf(str,"Number of seconds left before alert : %n",counter);				//MessageBox(hdwnd,str,"Test",MB_OK);				SetDlgItemText(hdlg,IDD_CTEXT,str);							}		}		return 1;	case WM_INITDIALOG:		si.cbSize = sizeof(SCROLLINFO);		si.fMask = SIF_RANGE;		si.nMin = 0;		si.nMax = VSCROLLMAX;		SetScrollInfo(hdwnd,SB_VERT,&si,1);		si.fMask = SIF_POS;		si.nPos = vPos;		SetScrollInfo(hdwnd,SB_VERT,&si,1);		SendDlgItemMessage(hdwnd,IDD_RB3,BM_SETCHECK,BST_CHECKED,0);		return 1;	case WM_VSCROLL:		switch(LOWORD(wParam))		{		case SB_LINEDOWN:			vPos++;			if(vPos > VSCROLLMAX)			{				vPos = VSCROLLMAX;			}			break;		case SB_LINEUP:			vPos--;			if(vPos < 0)			{				vPos = 0;			}			break;		case SB_PAGEDOWN:			vPos += 5;			if(vPos > VSCROLLMAX)			{				vPos = VSCROLLMAX;			}			break;		case SB_PAGEUP:			vPos -= 5;			if(vPos < 0)			{				vPos = 0;			}			break;		case SB_THUMBTRACK:			vPos = HIWORD(wParam);			break;		case SB_THUMBPOSITION:			vPos = HIWORD(wParam);			break;		}//exit inner switch statement		si.fMask = SIF_POS;		si.nPos = vPos;		SetScrollInfo(hdwnd,SB_VERT,&si,1);		return 1;	}//exit switch statement	return 0;}
