What's wrong with LVN_HOTTRACK notify handling. winyu16-Feb-02 5:22 winyu 16-Feb-02 5:22  (In VC++ 6) I create a CListCtrl control and want it show a tooltip when user lay the cursor on its each item. So I set the list control style to LVS_EX_TRACKSELECT and define a function to handle the LVN_HOTTRACK notify. The problem is the program work fine in debug config compile version but got error in release version. The error is come from the LVN_HOTTRACK function. (without it, the program got no error) Anyone please give me some suggestions. Thank you. Re: What's wrong with LVN_HOTTRACK notify handling. Joaquín M López Muñoz16-Feb-02 5:32 Joaquín M López Muñoz 16-Feb-02 5:32  Could you please post the code for the LVN_HOTTRACK handler? Joaquín M López Muñoz Telefónica, Investigación y Desarrollo my sourcecode is like this winyu17-Feb-02 7:59 winyu 17-Feb-02 7:59  ON_NOTIFY ( LVN_HOTTRACK, IDC_lstctl_THR, OnHottrackNotify ) ... BOOL CPXP_MainDlg::OnHottrackNotify ( NMLISTVIEW * pNMLV ) { return (FALSE); } (I put only 'return' to test the function, and it comeout fail) Re: my sourcecode is like this Tim Smith17-Feb-02 8:18 Tim Smith 17-Feb-02 8:18  That routine isn't a notify routine. It doesn't have all the arguments and what arguments it does have are wrong. The proper form is... afx_msg void memberFxn( NMHDR * pNotifyStruct, LRESULT * result ); Tim Smith I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk? Thank Tim, it's work !!! winyu17-Feb-02 8:54 winyu 17-Feb-02 8:54  you make me smarter thanks. Changing font without CFont-Member-Variable Rybeck16-Feb-02 4:00 Rybeck 16-Feb-02 4:00  How can I simple change the font style of a CEdit? (Maybe without m_Font?) I tried following, but doesn't work: void CMyEdit::OnChange() { LOGFONT logFont; CFont *pFont = GetFont(); if(!pFont->GetLogFont(&logFont)) return; logFont.lfUnderline = m_bShowUnderlined; if(!m_Font.CreateFontIndirect(&logFont, NULL)) return; SetFont(&m_Font); m_Font.DeleteObject(); } thx Re: Changing font without CFont-Member-Variable Mazdak16-Feb-02 4:35 Mazdak 16-Feb-02 4:35  m_youredit.SetFont(&font) of cource you have to create CFont object first.But it is very simple.

Unless your trying to syntax hilite your control or something...even still ownerdraw would probably work better. If you want your edit control to just display it's text in Italics or something... Change the font in InitDialog or something...previously your font change would occur every time some one presses a key or the contents change...thats a waste of cpu time. Cheers!

I'm unsure as how to do double buffing with GDI+. I like doing all my drawing in memory then flip it to the screen - with just GDI I could do that with ease. Can someone help me understand this with GDI+ ? How do you switch the two graphics associated with the dc's?

Check this site out when you have a chance. It's about the same thing just a different approach to it.

Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: search string for "//pasword=" Steven Richardson16-Feb-02 5:16 Steven Richardson 16-Feb-02 5:16  sorry i am not sure how to use std::strings? Re: search string for "//pasword=" Joaquín M López Muñoz16-Feb-02 5:29 Joaquín M López Muñoz 16-Feb-02 5:29  I think you will find it extremely useful to read some book about C++. For instance, Bruce Eckel's Thinking in C++ is very good for starters, plus you can download it for free! There you can learn how to use std::strings and a lot more. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: search string for "//password=" Steven Richardson16-Feb-02 6:14 Steven Richardson 16-Feb-02 6:14  thanks for all you help i think i will get that book Re: search string for "//pasword=" Uwe Keim16-Feb-02 5:23 Uwe Keim 16-Feb-02 5:23  Or use Regular Expressions to find the string. -- See me: www.magerquark.de Re: search string for "//pasword=" Paul M Watt16-Feb-02 6:56 Paul M Watt 16-Feb-02 6:56  If you are using the regular C-runtime libary with char* as your string you can use strstr(). This will search for a string inside of a string. OLE/COM 16-Feb-02 3:24 16-Feb-02 3:24  hello, Does OLE/COM use SendMessage(----) and other such message functions internally?

Re: where are the sound functions Domenic Denicola16-Feb-02 5:14 Domenic Denicola 16-Feb-02 5:14  I think you will need to download the Platform SDK first for at least some of them. Anyway, the PSDK is a really nice thing to have Get it at the PSDK Update Site: http://www.microsoft.com/msdownload/platformsdk/sdkupdate And to answer the original question, this should work with VC++ 6 once you have the PSDK Have fun! -Domenic Denicola- Geek^n http://madhamster.50megs.com "Any technology that is indistinguishable from magic is insufficiently advanced..."
