What's the point in the following code (generated by the app wizard)?
#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif

Well, these two objects are different beasts. __FILE__ is a macro expanding to the name of the file, i.e. everywhere you write __FILE__ is like you're writing instead "foo.cpp" or whatever the file is called. THIS_FILE is a true variable, not a macro, and moreover is mutable, which means you could even change its contents. As for the specific use of THIS_FILE I don't really know. Scanning thru the entire source code of MFC does not reveal any use of this variable.

To give a more formal answer than Joaquim's, this is necessary to display Debug information in the Debug Window.

Hi,
I've written a program to test the performances of a windows timer under different work loads. In a first step we used the program under a windows 98 platform with a timer frequency of 5Hz. So every 200msec the Wintimer should sent a WM-TIME message to the OnTimer function. Because the timer tick frequency of a windows 98 platform is about 18Hz(55msec) there will be approximately a time delay of 20msec. When I start the program with no work load(0 floating point operations) the time delay is also 20 msec, so everything is normal. But when I want to increase the work load to 1.000.000 floating point operations the time delay becomes smaller. I would expect that it would increase with increasing work load!
Can anyone explain this?
Kind regards,
Geert

My semi-educated guess: that your program is getting more scheduled time and can therefore respond quicker to the WM_TIMER message. My guess is that if there was another program consuming more CPU than yours, you might take longer to respond.

Hi,
I'm making a program that have a listview that lays on top of another window(different program). I'd like to show the context menu of the other window. I've tried to send a WM_RBUTTONDOWN message and also WM_CONTEXTMENU, but it doesn't work. Can anybody help me?
I hope my question is clear...

Well, not really ... What you mean by "show the context menu" ? You want to show the menu items as items in your listview ? Or you simlpy want to open the context menu of the underlying window when your program lays on the top of it ?

This one 
Just open the context menu of the underlying wnd

I think the WM_RBUTTONDOWN should do if you also give the focus to the underlying window, since if the focus directly returns to your own app, the menu vanishes before ever being displayed. So i think you retrieved the hWnd using GetWindow() ? use it to give the window focus, and then send the message.

Hey I've got my ListView showing the system icons for each file type, but for directories and a few other files the icon have a black border, instead of the 'transparent' shadow like in IE and others. This is on WinXP, just woundering how I get rid of them? or how to handle them properly, tried searching around and couldn't find anything and the example on CP shows the same 'black borders'.
Luke.
oh yeh I'm using WTL not MFC if that matters.

when i call PrintDlg with hDevNames set to printer installed at machine what is actually off (driver 'winspool' enabled to select it in previous PrintDlg call but DocumentProperties called after failed)
CommDlgExtendedError returns CDERR_MEMLOCKFAILURE
- all is ok when i set hDevNames to null before call
- when i try to do own GlobalLock to it it makes no problem
seems to me strange solution like:
if CDERR_MEMLOCKFAILURE try to call again with hDevNames=NULL
any experiencies with?

How can I get application path ?
My condition
1) The Application is already installed on computer
2) The Application is not running.
3) I want to get that application path
sample (acrobat reader, icq, etc...)
1) Acrobat Reader is already installed on computer
2) The Acrobat Reader is not running now.
3) I want to get that Acrobat Reader Path.
How should I do (Howto or Library) ?
Thank you for your kindness.

I think you have to write SEARCH code.

Well,Let me correct myself.You can do it with WMI.I never use it with VC myself but you can check it in MSDN.Look up Win32_SoftwareElement and Win32_InstalledSoftwareElement.

Look at the Registry entries.
Look at all the Registry functions in MSDN. With things like RegEnumValue, RegEnumKey, RegEnumValue you should find the application installed, and the path to it (the value in which these are stored are always the same, i.e. Reader should be under Acrobat Registry Key).

hi , i have 2 questions.
i need to put an image (200x200) on the top of my dialog box to make it look pretty. I can use any file format to do it, bmp,jpg, gif, im just unsure how to do it. pointers to articles / information on this is appreciated.
also...
I saw an article on here last week by some 'code jock software' etc.. and it was for adding a splash screen to an application... anyone have that link handy?? thanks

The Code Jock guy is Kirk Stowell, you can search for articles by author, he only has a few. Splash screens are pretty easy though, at worst you can just use the component that comes with VC to do it.

For splash screens, just look at the code of Wordpad in MFC Samples. What is done is :
You create a dialog containing only an image (or whatever) with no border or whatever, which is displayed by the app, and killed in the OnIdle function after a while. Intersting thing is you can display various things (like animations, or plug-in loading à la Acrobat Reader) doing it this way.
I never tried the splash screens in VC++ which Christian is talking about, however, it may be worth a try.
As yor displaying a bmp, with MFC, just create a CStatic somewhere and load a bmp in it. Might also go that way in Win32 API only.

you can use BitBlt() and StretchBlt() functions to get the job done and look up MSDN it has some samples on these 2 func's.
BitBlt() just places the bmp on to the dlg and using StretchBlt() u can stretch the bmp to any size u want.

cool! ! thanks everyone... im going to try to get these things working... the splash screen does sound simple enough. Though I played with CStatic last night and couldnt get the picture to display, i kept getting an error when I tried to load my bitmap ..(16-bit image, is that ok?). ill try documentation on the Bitblt() and StretchBlt to find out more on that task.
thanks,
josh
