We're building interfaces using pure virtual functions, and yes, we used pure virtual functions mostly when we needed interfaces.

I've got no way to verify this, but have you tried NetUserGetInfo()? You might also find something in the Remote Desktop Services API.

Well you should start by using all wide character functions, then fileNameLPW is redundant e.g.
WCHAR fileNameStr[20];
int indexOfFile;
wsprintf(fileNameStr,L"NEWFILE%d.WAVE",indexOfFile);
CreateWave(fileNameStr);

That should be swprintf or wsprintfW
(or use TCHAR instead of WCHAR and let the compiler macros pick the right windows function.)

I checked my spelling carefully before posting, and still got it wrong 
Thanks for correcting it.

hello coder
Is it posile to define same name macro in c project
like folloing
<br />
test1.h<br />
#define process (a&4) <br />
test2.h<br />
#define process (a&4) <br />
<br />

What are you trying to achieve here, this makes no sense?
|
|
|
|
|
maybe, but the compiler/preprocessor will probably report duplicate something.
But you could do something like (not really test, but I've seen code like in out stuff):
in test1.h
#ifndef process
#define process (a&4)
#endif
and in test2.h
#ifdef process
#undef process
#define process (a&4)
#endif
This signature was proudly tested on animals.

I still have no idea what you are trying to achieve

I am having a class which is inheriting CEdit class ..........
But when I try to do ctrl c and ctrl v in the edit box of my dialog it does not perform copy paste.
but if I right click and then copy and paste then it is working fine.

MFC dialog some times blocks keyboard messages for its controls - really no good.
You can override key-down message of CEdit to see if CTRL-C is sent to CEdit, if not, use PreTranslateMessage(...) of dialog to send messages you need to the CEdit.

I thought there was someting in resource files for defining a connection between particular key combinations and commands; ACCELERATORS or similar?

How can we remove/rename a manifest entry programatically?
|
|
|
|
|
A manifest is simply a resource stored in the .rsrc resource section of the executable. You can modify/update or remove it with the UpdateResource Function[^]. You need to call it with lpType argument set as RT_MANIFEST. RT_MANIFEST is #defined as integer 24.

Hi to All,
I am using a MS Flex Grid in my learning application. I have 3 columns in it.
Having a problem of selecting rows. Could anyone please help me out with the following problems
1.
..Whenever I select a row, the blue line appears only for the 2nd and 3rd columns in that row, not for the first one in that row.
2.
..I want to use the arrow key to select columns. Is there any inbuild method for that, or I need to program it.
3.
.. To delete a row by pressing the delete column.
Please help me
thanks in advance.
