Re: RGB to HSB Conversion.. 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.. Neha15-Mar-02 1:43 Neha 15-Mar-02 1:43  Thanks for the reply. But the HSL Value i will get through that function won't match with the value displayed in the window standard color dialog box. 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. That is not preferrable, because the class is shared over lots of different projects Check CDialog::CreateIndirect then. It allows you to create dialog template in memory - no resources required.

I dunno that they need to be in an image list. The most common approach is to put all the individual frames into one bitmap and calculate your position within that bitmap ( i.e. they are positioned evenly so that jumping your across and down positions by a constant value creates frames that animate ) and do a bitblt of the part you need.

Davidlou14-Mar-02 19:54 Davidlou 14-Mar-02 19:54  I extracted the system32\vbscript.dll to get the type library(named RegExp.tlb). Then I add the new classes from this tlb to my project! Then I want to new one class of them named IRegExp(derived from COleDispatchDriver), but i don't know whether i need to attach the LPDISPATCH to this instance and how can i do! When i didn't attached it, that is called its default constructor, and run it, I can't not execute it normally! This program is too emengent, so i need ur warmhearted help in time! [ccode] void CInetSessionDlg::ParsePage(CString szPattern, CString szContent) { //m_regExp's declaration is on other place link this: IRegExp m_regExp; //The class IMatchCollection and IMatch are both got from the tlb IMatchCollection * temp; m_regExp.SetIgnoreCase(TRUE); m_regExp.SetPattern(szPattern); if(m_regExp.Test(szContent)) { temp=new IMatchCollection(m_regExp.Execute(szContent)); for(long i = 0; i < 3/*matches.GetCount()*/; i++) { //IMatch match = matches.GetItem(i); IMatch match = temp->GetItem(i); CString strLink = match.GetValue(); m_cbHref.AddString(strLink); } } } [/ccode] Thanks u very much!
