Hello all! Is it possible to call LoadPosition, but for it not to actually display the main frame? The problem is that if I wish for the application to start minimized, I don't want to see the widow poping up and then getting minimized, but a call to LoadPosition from InitInstance does that. If I don't call LoadPosition, then the main window is not created properly (the CXTPTabClientWnd is not created it seems). Thanks in advance! ------------- // W7 64 Ultimate SP1 // VS 2008 // CodeJock 16.2.3 (MFC) |

Hi, What is "LoadPosition" there is no such API and we don't have any class that has such method. ------------- Oleg, Support Team CODEJOCK SOFTWARE SOLUTIONS |

Oops, sorry - I meant LoadWindowPos(). This is how I have it: bool CMainFrame::LoadPosition() { bool bRet = m_wndPosition.LoadWindowPos(this,_T("mainFrame")); GetCommandBars()->RedrawCommandBars(); return bRet; } ------------- // W7 64 Ultimate SP1 // VS 2008 // CodeJock 16.2.3 (MFC) |

| Usually in such cases you can prepare everything in hidden widow state and show windows when you needed - still all your geometry will be proper e.g. you can dock control bar by x,y - coordinates |

Yes, I do have my window in the hidden state, but it becomes visible as soon as this is hit: pWnd->SetWindowPlacement(this); (inside the LoadWindowPos() function) ------------- // W7 64 Ultimate SP1 // VS 2008 // CodeJock 16.2.3 (MFC) |

You right - but you can overwrite this function and use
CWnd::SetWindowPos instead of CWnd::SetWindowPlacement
BOOL CXTWindowPos::LoadWindowPos(CWnd* pWnd, LPCTSTR lpszWndPos/*=NULL*/, LPCTSTR lpszSection/*=NULL*/)
{
ASSERT_VALID(pWnd); // must be valid. if (::IsWindow(pWnd->m_hWnd)){ if (LoadWindowPos(lpszWndPos, lpszSection)){ pWnd->SetWindowPlacement( this); return TRUE;} } return FALSE;} |

This is piece of SaveWindowPos function:
it always keep stored showCmd of WINDOWPLACEMENT as SW_SHOWNORMAL or SW_SHOWMAXIMIZED
// Make sure we don't pop up
// minimized the next time
if (showCmd != SW_SHOWMAXIMIZED)
{
showCmd = SW_SHOWNORMAL;
}
so in YOUR LoadWindowPos you can change showCmd before SetWindowPlacement call and it will be hidden or minimized as you with. Be careful with potential popups!
BOOL CXTWindowPos::LoadWindowPos(CWnd* pWnd, LPCTSTR lpszWndPos /*=NULL*/, LPCTSTR lpszSection/*=NULL*/){
ASSERT_VALID(pWnd); // must be valid. if (::IsWindow(pWnd->m_hWnd)){ if (LoadWindowPos(lpszWndPos, lpszSection)){ pWnd->SetWindowPlacement( this); return TRUE;} } return FALSE;} |

Overriding the LoadWindowPos() seems to work (I pass in a bool specifying whether to hide the window or not). This is what I've got now: BOOL CMyXTWindowPos::LoadWindowPos(bool bHide, CWnd* pWnd, LPCTSTR lpszWndPos/*=NULL*/, LPCTSTR lpszSection/*=NULL*/) { ASSERT_VALID(pWnd); // must be valid. if (::IsWindow(pWnd->m_hWnd)) { if (__super::LoadWindowPos(lpszWndPos, lpszSection)) { if(bHide) { showCmd = SW_HIDE; } pWnd->SetWindowPlacement(this); return TRUE; } } return FALSE; } I didn't exactly understand what you mean about popups - can you please explain a bit more? Thanks! ------------- // W7 64 Ultimate SP1 // VS 2008 // CodeJock 16.2.3 (MFC) |

| Of course it will work. Popup means that some app have popup appears on some state. Better for user-friendly desigh to have visible owner of such popup othercase popup can be under some other app and user will mo see it. Example - Google notifier which popup login dialog but sometimes under OutlookExpress window |
