Hi , thank you for the message. I know very good a sequences of the attribute changes…
The SetFileAttributes will not allow to change directory to file. I need some FAT32 or NTFS direct functionality , probably at the low level file access. Like it was with Norton Editor for DOS. NE for DOS allowed to change attributes from directory to file, and you are right, everything under that directory disappeared for the DOS. In my case it is a fast way to remove full path.

Ah, OK.
Thanks for the explanation of what you are trying to do.
Sorry - I can not offer any suggestions.

I want to write an application that overlays information on the window(s) of another external application. Basicly I want to draw information on that applications window. Does anybody have a clue on how to do this?
I can think of two strategies:
1. Write the information on a transparent window an make sure that the windows stays over the application I want to modify through constantly monitoring the window hierarchy.
2. Make som kind of hook in the external program and capture paint events. After the original paint is done I have some own code that writes what I want over the GUI.
I think I would prefer the first strategy if it is possible, since it is less intrusive and eaisier to adopt to different kinds of applications. But I don't know if it is possible to do a window that is completly transparent to mouse and keyboard events. I wouldn't want my application to steal the focus from the application I modify. The modification should be visual only. Another problem is that I guess it might be hard to make the Z order and positioning to be in perfect sync all the time (although short missalignments is acceptable).
Does anyone have an clue of which API calls to use to make such a system? Does anyone have any sample code that does similar things?

You can use CImageList.
CImageList.BeginDrag
CImageList.DragMove
CImageList.EndDrag
Above will satisfy your request.
It supports transparent drawing. but you would need some trick.

If you give the window the WS_EX_TRANSPARENT extended style, it will pass through mouse clicks to the window beneath it. As for the Z-order issue, I'm not sure what would be the best way to solve it. It may be easier simply to hook the window and subclass it, and redo the painting.

I don't think so, message are #define, so they will be replaced at compilation.

Ok, thanks. My next question will be, why not? It is not like Microsoft is going to change the values from version to version.

Why keep a string in an application if only the numerical ID is important ? imagine if in any application you would keep a string equivalent of each ID ( resources, and messages ) ... the application would grow for nothing.
and it's much more efficient to compare integer values than strings.

I am playing with global/local hooks. Now I intercepted all those messages in my hook procedure, I want to print the messages to a log file (I want readable names instead of numeric values so that I can figure out what I can do with the hooks).
According to what you said, there is no API that can give me the message names except writing a giant "switch" block myself, right?

Just create a map within your application. See MFC's CMap class for starters. STL probably has a similar collection. You could try FormatMessage().

In the VC watch window, enter "116,wm" and it'll show the text version if it is available.

Thanks. What I am looking for is a way to get the text of a windows message from my code so that I can print readable information into a log file.

I'm not aware of any API. A good amount of the messages change meaning
depending on the window class of the recipient. The nearest to a cunning idea I have is to parse windows.h...
Tedious, admittedly.

I used VC++6 a few years ago and then was out of programming for a long while. Trying to get back to it again (C++) using VS .Net 2003. Got a book (Step by step) where the author shows:
Console.Write(S"....");
What does the 'S' do? I've seen it with and without it and it seems to work the same either way. Where can I read about? I've tried looking in the .net help but I guess I'm not using the right search.
Thanks,
Jose

The S prefix on a string literal means "this is a managed Unicode string".

I get the string in each iteration of loop and i have to append that string at the end of file, but i am not getting the all values , file only shows(have) last written value in it.
I am using the code below:
CString text; //assume text var have different value in each iteration
For ( int i = 0 ; i <=5; i++)
{
CString filename = "f:/ TestFile.pc" ;
CFile files;
files.Open( filename , File::modeCreate|CFile::modeReadWrite|CFile::typeBinary);
files.Seek(0L,CFile::end);
files.Write(text , text.GetLength ());
//
files.Close ();
}
Regards.

First it was created by the code ,
Then after that want to append in already existing file.
So what Flags I should use, please tell me for writing 2nd time and so on
Regards.

The attribute File::modeCreate will cause the existing file to be truncated to a zero length every time you open it. So when you next Seek it won't do anything. You also need to open it with the attribute of File::NoTruncate.

Hi!
I'm trying to install my app on a computer where VS is not installed. For some reason it does not work. I tried to use depends.exe to find out where the problem is but I don't really know what to do with the results:
GetProcAddress(0x77BA0000 [MIDIMAP.DLL], "midMessage") called from "WINMM.DLL" at address 0x76AE3AFE and returned NULL. Error: Procedure cannot be found (127).
Second chance exception 0xE06D7363 (Microsoft C++ Exception) occurred in "KERNEL32.DLL" at address 0x7C81EB33.
Exited "VRSOFT20.EXE" (process 0x584) with code -529697949 (0xE06D7363).
Entrypoint reached. All implicit modules have been loaded.
The dll have the same version on both computers. What's wrong???

How can I rewrite
template < class Class1 > typedef friend class Class2;
so that it is compatible with .NET's compiler?
Any help is very appreciated.
