Hi guys,
In VS 6 C++ there was no Bool CArchive Operator so we made one of our own where it used an int for true = 1 false = 0, naturally.
Now I see .NET C++ they have been clever and added one of their own, how can I disable that and use my own without having to derive a class from CArchive and overloading it??
I would be interested to hear if anyone else has this problem

I guess you defined your homemade operator as a global CArchive& operator<<(CArchive& ar,bool b), right? If so, and if you can afford some syntax ugliness, you can force selection of this operator instead of the built-in one by calling it explicitly like this:
CArchive ar;
...
operator<<(ar,true);
operator<<(ar<<1<<2,false)<<3<<4;

In some cases, these exceptions are caused by calls to the Win32 API from your program with incorrect parameters --check for that inspecting the particular API where the exception is showing. Could you post the offenging code? Other than that, caught first-time exceptions is the handler's businesses. I wouldn't worry too much if everything's working.

Hi !

If you already hava a window handle for that app (obtained for instance with FindWindow), <a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/windows_5y90.asp">GetWindowThreadProcessId</a> gives you the associated process handle.

PS: Oops, did I say process handle? GetWindowThreadProcessId gives you the process id. From this you can retrieve the process handle with <a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dllproc/prothred_478z.asp">OpenProcess</a>. Regards.

Experiment with ShellExecute. You don't need to specify the executable name for the Windows Media Player, just the name of the .AVI file (ShellExecute will know how to locate the player for the file.)

Simple:
Use "Media Player ActiveX",its one standard activex in visual studio.

is it possible to change the project after the application has been created. i.e., I'm using a demo software of the net, project was called OpenGL, but I wanna change the name. If I can't do that, I atleast wanna be able to change the title when i bring up the MDI window. I don't want it to say openGL. How can I do this?

|
|
|

Yes is posible. Edit the file .dsw and .dsp with notepad and change the names and reference to old name...
Y think that CP has any aplication that make that, but is more quickly edit the files and change the names that look for the application...;)

If you want to change the application name that appears in the captions of the various windows created by the app you can do that by modifying the relevant strings in the string table resource (e.g. IDR_MAINFRAME, IDR_<yourappname>TYPE, AFX_IDS_APP_TITLE etc).

Hi, I'm just starting to learn visual C++.
Can someone give me a simple and concise explanation of the differences between a win32 debug and a win32 release application. i.e., what does each mean, and how will it affect the program.

"Debug" and "Release" are different configurations under which you can produce the final executable from your project files. Debug .EXEs are meant to be used in the debugging process, while release .EXEs do not have any such debugging aids and are typically smaller and faster. When compiling in debug mode, the macro _DEBUG is defined, while in release mode it is NDEBUG which is defined (also, _DEBUG is not defined in release mode, of course). Some of the debugging aids included in a debug executable are:- Debugging versions of the functions in the C run-time library that check for common errors like passing null pointers, memory leaks, etc.
- Macros such as
assert are included in the executable.
- Information is included that gives you the possibility to set breakpoints, watch the contents of variables in run-time, do step-by-step running, etc.
- The code is not optimized to preserve a mapping between source code and generated machine code. In release mode, a lot of optimizations are applied that frequently reverse the order of sentences, eliminate temporary variables, an so on.
So, use debug mode when testing your program and release when giving it away.

Joaquín's reply explains the differences between Debug and Release mode very well. I'd just add that if you execute code (that must run in release mode) using ASSERT, you should change it to VERIFY. Eg:
ASSERT (x > 0);
ASSERT (myFunction (x) == SUCCESS);
should be
ASSERT (x > 0);
VERIFY (myFunction() == SUCCESS);

Sure. Use <a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/rras/rasclnt_3rar.asp">RasEnumConnections</a> to get a list of available connections. To retrieve number and user, use <a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/rras/rasclnt_4boz.asp">RasGetEntryProperties</a> and <a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/rras/rasclnt_681f.asp">RasGetEntryDialParams</a>, respectively.

I've got only october's MSDN issue where the quite little information is given on how to use that "Visual Styles API". Can anyone give a link to some detailed manual???

Are you joking? There's nothing useful. Do you think that that writing can really help to make the program like "Style XP" !?
