Re: Menu Item appears Grayed in MFC Rick York13-Dec-01 11:00 Rick York 13-Dec-01 11:00  You are exactly right and that is why it annoys me so much. I have figured out how to play their game though and remove the NO_DEPENDENCY line with a minimum of headache. I do this in nearly every project I work on. With the speed of computers these days I can think of no good reason to have anything NOT dependent on resource.h that uses it. It only causes problems and does provide no benefit. Re: Menu Item appears Grayed in MFC 13-Dec-01 11:44 13-Dec-01 11:44  Finally I found out the solution. I didn't associate the Menu to Main Frame. Instead I did to one of the views. Surprisingly it let me pick a view. Difference of behavior: WXP vs W2K ??? Mickael Pointier13-Dec-01 5:51 Mickael Pointier 13-Dec-01 5:51  Hi. One of the applications I've coded refuse to work correctly on WinXP (but was working fine for months under Windows 2000). I wonder if someone else notice this kind of problem. More specificaly, I'm using anonymous pipes to make the two parts of my application communicate, but unfortunately the created process never get the handle of the pipes the main process creates. It results in the fact the the child process get the standard STDIN/OUT/ERR handles when it does GetStdHandle(). [Note: I'm not using CreateProcess, but CreateProcessWithLogonW. I can send a part of the code if it helps.] Hungar Convention/Norm/Method Carlos Antollini13-Dec-01 4:24 Carlos Antollini 13-Dec-01 4:24  Any body here Know where I can find some documentation about that?

It is my impression that Hungarian notation has fallen into some discredit during the last years, mainly because it promotes a very loose way of type checking. Languages more modern than C (like C++) have stricter type checking systems that render this kind of nmenomics redundant in the best case (or false in the worst, if you changed the type of a variable and forgot to rename it).

If you're interested in this subject, check this funny article by Jim Hyslop and Herb Sutter against Hungarian notation.

Estaba interesado en esa notación porque un compañero de trabajo no la conoce. I was interested in that notation because a co-worker don't know it... Joaquín, Thanks again Muchas Gracias....

Could someone show me what libraries they link to in a project that works? Any suggestions would be so helpful... Thanks, ~Tim SHABBA!! Re: CoInitializeEx ( ) Chen Venkataraman13-Dec-01 4:24 Chen Venkataraman 13-Dec-01 4:24  Add this before the standard headers are included in your stdafx.h file #define _WIN32_WINNT 0x0400 Chen Venkataraman Re: CoInitializeEx ( ) Tim Rymer13-Dec-01 4:31 Tim Rymer 13-Dec-01 4:31  Let's all say it together kids: "Chen Venkataraman is THE MAN" thanks a whole whole whole whole whole bunch. *BIG SIGH OF RELIEF* ~Tim SHABBA!! Re: CoInitializeEx ( ) Chen Venkataraman13-Dec-01 4:41 Chen Venkataraman 13-Dec-01 4:41  BTW, you could also do the same with Project Settings -> C/C++ -> Preprocessor & add this _WIN32_WINNT=0x0400 to the defines Chen Venkataraman Thousand seperator User 988513-Dec-01 4:03 User 9885 13-Dec-01 4:03  Have anyone come across any function that can format a number with thousand seperators?

Assume that I have an icon in the DLL resource named IDC_SAMPLE. How can I get an HICON for that? I need this to change the icon in the title bar of a dialog. HICON hiconSample; // ??? SetIcon(hiconSample, FALSE); SetIcon(hiconSample, TRUE); Thanks.... Change the screensaver from a program... Anders Molin13-Dec-01 2:37 Anders Molin 13-Dec-01 2:37  Does anyone know how to change the screensaver to another one. I know I can change the HKCU\control panel\desktop\scrnsave.exe value, but then the user have to reboot. Is there an API to do it? I can set some properties on the screensaver with SystemParametersInfo(), but I cant find a way to tell the system that I have changed the scrnsave.exe registry value... Any ideas? - Anders Money talks, but all mine ever says is "Goodbye!" WinXP dialog fonts for VC++5 apps Steve Kearon13-Dec-01 1:53 Steve Kearon 13-Dec-01 1:53  When running my VC++5/MFC app under XP, most dialog fonts look bad. Fonts in property pages & common dialogs look great (except for added controls in FileOpen). Fonts in menus and messageboxes look great, too. Adding a manifest file makes no difference to the fonts, but verything else turns cool<g>. From scouring MSDN/KB it seems the trick is to specify dialog resources to have style DS_SHELLFONT and use the "MS Shell Dlg" font (rather than "MS Sans Serif"). However ... in VC++5, DS_SHELLFONT isn't defined and I can't specify "MS Shell Dlg" (because its not availalable on my development system?) Is my understanding of the issues / solution correct ? Is there a way to achieve what I need with VC++5, or must I upgrade to VC++6, or what ? Many thanks Steve Kearon Re: WinXP dialog fonts for VC++5 apps Michael Dunn13-Dec-01 7:42 Michael Dunn 13-Dec-01 7:42  You need to do three things: Change the DIALOG resource to DIALOGEX (just add the "EX" in a text editor). Change "MS Sans Serif" to "MS Shell Dlg". (MS Shell Dlg isn't a physical font, you won't find it on any system. It's a special name the OS recognizes.) Add DS_SHELLFONT, which is equal to DS_SETFONT | DS_FIXEDSYS --Mike-- http://home.inreach.com/mdunn/ "Not our fault we are intellectually superior to the rest of the office." -- Paul Watson in the Lounge, 12/12/2001 Sonork - 100.10414 AcidHelm char to integer 12-Dec-01 20:16 12-Dec-01 20:16  i'd like to convert between a char and int! from CString.GetAt(int) i get a char ( or unsigned short) how do i change this to an integer (to get the ASCI code)???????

Erik Funkenbusch12-Dec-01 17:46 Erik Funkenbusch 12-Dec-01 17:46  Why do you care about the system idle time? I have to think you're really trying to do something else, like calculate uptime or something. What are you trying to do? -- Where are we going? And why am I in this handbasket?
