What are the error messages?

It could be from some clean-up code or many other things. It would be easier to offer ideas if you provide the errors messages themselves.

As said by Leah_Garett,
It may be bacause of some clean-up code. You need to debug it. Or tell exact error message.

Is there a way to do this? I am familiar with setting the alphablend levels on the main window and making it transparent but when I try to do the same for child windows nothing ever happens.

If you want to transparent window I think you can see an example of codeproject about it.I think It has four window that are transparent (child window)

enumerating users logged on to the windows messenging system

Hi,

If anyone's not familiar with the windows "net" program, it sends messages to people based on a given user or computer alias.

Does anyone know how to enumerate these aliases? I've basically scoured the web. I'm looking for a way to do it in C++, and i'm thinking that there's probably some kind of obscure networking function that I've missed. Big Grin | :-D

Thanks for your help everyone.

Does WNetOpenEnum() give you what you're looking for?

That's "net send" actually. "Net" by itself does nothing.

Hey, thanks for the help.

I don't think WNetOpenEnum was quite what i was looking for, but through that i found NetQueryDisplayInformation, which is closer to what i want.

The comment about the program being "net send", the program is actually "net", but "send" is an argument it takes. therefore "net send" is used to send a message using the "net" program. On that note, the "net" program has alot of extra useful functionality which i might try out.

Thanks for your help guys.

Check if file is there or not [modified]

FredrickNorge5-Dec-06 11:38

I curently have this code

bool FilesClass::FilePath(char name[50])
{ int buffer;
int fh;
if( _sopen_s( &fh, name, _O_BINARY, _SH_DENYWR, 0 ) )
{
Files++;

buffer=strlen(name);
strncat(DllStatus,name,buffer);
strncat(DllStatus,";",2);

return false;
}
else
return true;
}

But in some cases it fails to process the checks, and asserts with cant open file.

My idea is that this function either returns true if the file is present, or false if its not, any sugestions?

What do you mean fails to process the checks?

How about something like this:

bool FilesClass::FilePath(const char *name)
{ 
	int buffer; 
	int fh;
 
	errno_t errno = _sopen_s( &fh, name, _O_BINARY | _O_RDONLY, _SH_DENYWR, _S_IREAD );
 
	if( errno )
	{ 
		if (errno == ENOENT)
		{
			Files++;
 
			buffer=strlen(name);
			strncat(DllStatus,name,buffer);
			strncat(DllStatus,";",2);
		}
		else
		{
			// _sopen_s() failed!
		}
 
		return false;
	}
	else
	{
		_close( fh );
		return true;
	}
}

The pmode param is required in the call to _sopen_s().

Note that if the file is already opened elsewhere without read share access FilePath() will
return false.

_access(..., 0) sounds a whole lot simpler.

So just add the contents of each folder to its own array. If the size of the arrays are different, or if one array has an item that the other does not, then you know the folders are indeed different.

Is there any way to statically link with kernel32/ntdll?

sunriseway5-Dec-06 10:08

Hi Forum,

Is it possible to write a simple hello world win32 application which is statically linked with kernel32 and ntdll? When I run the ap, only the executable image should be in memory and no other modules (including the kernel32/ntdll which are normally loaded). I want to build a fully self-contained executable. Is that doable?

Thanks in advance for any information.

sprintf vs strcpy

Blake Miller5-Dec-06 9:02

Blake Miller

5-Dec-06 9:02

So I see a lot of code like this lately:

sprintf(pUserPwd, "%s", oVerifedWriteDlg.m_UserPwd);

Why use that instead of just going with strcpy?

strcpy(pUserPwd, oVerifedWriteDlg.m_UserPwd);

Am I missing something?

I am inclined to think the sprintf would be a lot slower ... D'Oh! | :doh:
