I have this in my message map: ON_WM_MOUSEWHEEL( ) ON_WM_LBUTTONDOWN( ) and these functions defined: BOOL CMainFrame::OnMouseWheel( UINT nFlags, short zDelta, CPoint pt ) void CMainFrame::OnLButtonDown(UINT nFlags, CPoint point) OnMouseWheel gets called and works fine, but OnLButtonDown never gets called. Am I missing something terribly obvious here? thanks in advance Re: Confusing Mouse Operations radiox22-Aug-04 15:43 radiox 22-Aug-04 15:43  Doesn't matter anymore, I fixed it, ta much dialog, edit control - No.2 emo75u22-Aug-04 13:40 emo75u 22-Aug-04 13:40  Thank you Ivan! That´s exactly what I want, but my member variables are from typ double (str is a string), so I have got problems. In addition I don´t know where I have to place my function m_sB = 1.56 * m_sA. Sorry, I am new in C++. Re: dialog, edit control - No.2 Ivan Cachicatari23-Aug-04 8:05 Ivan Cachicatari 23-Aug-04 8:05  The expresion m_sB = 1.56 * m_sA, must be numerical values no strings. In this case create new button control on your dialog and add click event for this control: void CYourDialog::OnButtonClick() { if(UpdateData()) { m_dVariableB = 1.56 * m_dVariableA; UpdateData(FALSE); } } The m_dVariableB and m_dVariableA must be double(or any numerical type) and declared width classwizard. Use the hungarian notation to identify and declare variables. Ivan Cachicatari www.latindevelopers.com Theme madness!

GDI Objects in Windows Task Manager Jörgen Sigvardsson22-Aug-04 9:18 Jörgen Sigvardsson 22-Aug-04 9:18  I was looking at the task manager to see if I was leaking anything in my app. I saw GDI Objects increment when I did stuff. But it didn't decrement as much as it increment when I undid the previous operation. I quickly created a WTL application using the WTL wizard, executed it and opened the about box. It didn't decrement fully either. So, my question is; should I worry or is Windows garbage collecting GDI objects for later disposal? -- ...Coca Cola, sometimes war...

Do you know how true that claim is? I haven't used BC in quite some time so I can't comment. GC has been around for a long time and gets better with each release. My main use is its profiling which from memory BC didn't (doesn't) have. I find this alone is invaluable for quickly finding cpu intensive code.

Re: GDI Objects in Windows Task Manager PJ Arends22-Aug-04 11:24 PJ Arends 22-Aug-04 11:24  Depends, if the GDI count climbs to a certain level, and then stays there, I wouldn't worry about it. If it keeps on climbing then you definitely have a GDI leak that you have to deal with or your app will eventually crash.

If so, how is it done? Re: function pointers... Neville Franks22-Aug-04 10:52 Neville Franks 22-Aug-04 10:52  You may find this article http://www.codeproject.com/useritems/polycontainer.asp[^] of help. If you need to call these functions in specific class instances then you will need to hang on to their 'this' pointer or use something like delegates: http://www.codeproject.com/cpp/FastDelegate.asp[^] I can't see why you'd want to store function pointers in a map though!

Michael Gunlock22-Aug-04 5:41 Michael Gunlock 22-Aug-04 5:41  Does anyone know what determines the LOGFONT values received by the EnumFontFamExProc callback function (for TrueType fonts). At least on my test system, it is not affected by current dpi settings. It's easy to calculate the point size for the values received but I do not appreciate any patterns. For example, some fonts have values that are related to 24 point and others to 12 point. Are they values embedded in the *.ttf file?...perhaps related to a master glyph size? CListBox AddString() Anonymous22-Aug-04 3:23 Anonymous 22-Aug-04 3:23  is there a way to format the string? when I have multiple lines of names like this: abc defg abcde fghij i have been trying to make them line up vertically but couldn't. Any advice is appreciated Re: CListBox AddString() Dominik Reichl22-Aug-04 6:31 Dominik Reichl 22-Aug-04 6:31  Maybe try using tab characters (encoded in source using '\t')... abc\tdefg abcde\tfghij You can set the tab width using the BOOL SetTabStops( int nTabStops, LPINT rgTabStops ); function of CListBox. See MSDN for more. Best regards, Dominik _outp(0x64, 0xAD); and __asm mov al, 0xAD __asm out 0x64, al do the same... but what do they do?? (doesn't work on NT) Re: CListBox AddString() Ravi Bhavnani22-Aug-04 7:28 Ravi Bhavnani 22-Aug-04 7:28  A quick fix would be to set the listbox control's font to a monospaced one. You may also want to consider using a CListCtrl. /ravi My new year's resolution: 2048 x 1536 Home | Articles | Freeware | Music ravib@ravib.com How do I refuse to resize if a window is getting too big/small?

I know how to detect the last thing, but not how to stop resizing. Re: How do I refuse to resize if a window is getting too big/small? Andrew Peace22-Aug-04 5:30 Andrew Peace 22-Aug-04 5:30  Handle WM_SIZING and check the lParam value. If the RECT gets too large or small, change it accordingly. -- Andrew.
