About dialog Resizing properties border

Visual C++ General

YaelS

Hi,

I'm tring to set Resize able to mt dialog, but if I drag the border I get runtime error:

Unhandled exception at 0x0040a91e in QmAgent.exe: 0xC0000005: Access violation reading location 0x0000001c.

afxwin2.inl - (here it's break)

_AFXWIN_INLINE void CWnd::GetWindowRect(LPRECT lpRect) const

{ ASSERT(::IsWindow(m_hWnd)); ::GetWindowRect(m_hWnd, lpRect); }

I don't know why It's happend !

Thank's

Try debug into it, and make sure all pointers or handles are properly initialized with valid values.

Could you provide more context of the problematical code Preferablely all code that will be executed when draging border.

in afxwin2.inl file:

Code Snippet

_AFXWIN_INLINE UINT CWnd::ArrangeIconicWindows()

{ ASSERT(::IsWindow(m_hWnd)); return ::ArrangeIconicWindows(m_hWnd); }

_AFXWIN_INLINE int CWnd::SetWindowRgn(HRGN hRgn, BOOL bRedraw)

{ ASSERT(::IsWindow(m_hWnd)); return ::SetWindowRgn(m_hWnd, hRgn, bRedraw); }

_AFXWIN_INLINE int CWnd::GetWindowRgn(HRGN hRgn) const

{ ASSERT(::IsWindow(m_hWnd) && hRgn != NULL); return ::GetWindowRgn(m_hWnd, hRgn); }

_AFXWIN_INLINE void CWnd::BringWindowToTop()

{ ASSERT(::IsWindow(m_hWnd)); ::BringWindowToTop(m_hWnd); }

_AFXWIN_INLINE void CWnd::GetWindowRect(LPRECT lpRect) const

{ ASSERT(::IsWindow(m_hWnd)); ::GetWindowRect(m_hWnd, lpRect); }

I think my problem is that it's win32 project and I add to the code MtDialog dlg, dlg.DoModel()

MtDialog is CDialog..wrote in mfc.

Sorry that I didn't explain it clearly, I mean your code not the code in afxwin2.inl, this is where the assertion happens, but the real cause is outside this file, so I need to see the problematical code in your project, not in this file. You can use debugger to find where exactly the assertions happens, and paste out these code with enough context. If the project you have is not very big, you can think about paste them all here.

Sorry to, Ill explain mtself:

If I'm jest resizing the dialog, everything is ok!

My problem is when I resize the controns in my dialog:

I'm using this like this project: http://www.codeproject.com/dialog/easysize.asp

I think is about the mapping...I found my problem. :ES_HCENTER

So I'm OK!!!

EASYSIZE(IDC_STATIC3,ES_KEEPSIZE,ES_KEEPSIZE,ES_BORDER,ES_BORDER,ES_HCENTER)

this is my code:

in stdafx.h I add

#include "easysize.h"

class CListViewDlg : public CDialog

{

CListViewDlg(CWnd* pParent = NULL); // standard constructor
