Re: Avoid Moving a window Prem Kumar15-Mar-02 2:33 Prem Kumar 15-Mar-02 2:33  Hi, I guest windows provides the default action for moving u cannot stop the moving, but u can get back to the same position by using some thing ilke that foll code. In WM_INITDIALOG, take the window rect and on OnMove code it like the foll. void CTstNoMoveDlg::OnMove(int x, int y) { CDialog::OnMove(m_Rect.left, m_Rect.top); if( m_Rect.Width() > 100 ) ::SetWindowPos(m_hWnd,HWND_NOTOPMOST,m_Rect.left,m_Rect.top,m_Rect.Width(),m_Rect.Height(),/*SWP_NOSENDCHANGING*/SWP_SHOWWINDOW); } The reason for the If condition is a WM_MOVE is sent before the dialog is even properly instantiated at this pt the size might be rather less.

Tomasz Sowinski15-Mar-02 1:19 Tomasz Sowinski 15-Mar-02 1:19  If you want RGB to HSV conversion, check this link: http://www.cs.rit.edu/~ncs/color/t_convert.html Tomasz Sowinski -- http://www.shooltz.com Re: RGB to HSB Conversion..

Re: RGB to HSB Conversion.. Tomasz Sowinski15-Mar-02 2:06 Tomasz Sowinski 15-Mar-02 2:06  HSL is slightly different than HSV.

I'd like to subclass the system menu of my dialog based app. Any ideas how I can do it please? Thanks Jeremy Davis http://www.astad.org Re: Sub-Class System Menu Tomasz Sowinski14-Mar-02 23:59 Tomasz Sowinski 14-Mar-02 23:59  I've never done that, so treat this as educated guess Use SetMenuItemInfo and pass MFT_OWNERDRAW in the fType field of MENUITEMINFO struct. This makes menu item owner-drawn. Have no idea how your class works, but you should at least get WM_MEASUREITEM and WM_DRAWITEM messages.

Does Anyone has an example or suggestion ? Re: simple busy window Tomasz Sowinski14-Mar-02 23:53 Tomasz Sowinski 14-Mar-02 23:53  Busy == what? There will be some background work when dialog will be displayed?

Is it a worker thread, or idle time processing or something else? Tomasz Sowinski -- http://www.shooltz.com Re: simple busy window NikoTanghe15-Mar-02 1:05 NikoTanghe 15-Mar-02 1:05  Something like this: (like the MFC class CWaitCursor) { CWaitDialog Wait(_T("Wait a moment")); //Perform heavy operation } //destructor is called, Close Dialog Re: simple busy window Tomasz Sowinski15-Mar-02 1:14 Tomasz Sowinski 15-Mar-02 1:14  There's a problem with this approach. While your program performs 'heavy operation', no window - including main one and even your dialog - can be repainter. So your app will be basically frozen; all you can do is display a dialog with progress bar, but can't even have Cancel button. You may consider moving background work into separate worker thread. Or - you can pump the messages periodically during 'heavy operation'. Check the CWaitDialog class described by Jeff Prosise in the Wicked Code column in Feb'97 issue of MSJ. This article may be included in the MSDN installed on your harddisk; search for 'CWaitDialog'. If it isn't there, you'll should be able to find the article at msdn.microsoft.com Tomasz Sowinski -- http://www.shooltz.com Re: simple busy window NikoTanghe15-Mar-02 1:21 NikoTanghe 15-Mar-02 1:21  Thanks, But, I've already tried this approach. The class works fine. The problem is that a resource template is needed. That is not preferrable, because the class is shared over lots of different projects Re: simple busy window Tomasz Sowinski15-Mar-02 1:23 Tomasz Sowinski 15-Mar-02 1:23  NikoTanghe wrote: The problem is that a resource template is needed.
