CString::GetBuffer(...);
CString csStr = _T( "Somestring" );
LPCTSTR szBuff = (LPCTSTR)csStr;
LPTSTR szBuff1 = csStr.GetBuffer();
LPTSTR and LPCTSTR are WCHAR* and CONST WCHAR* type respectively.

Hi, there,
I would like to realize a function that can create a folder called "data" in a directory if it doesn't exist. Here is my code:
CString strPath ="D:\\temp";
SetCurrentDirectory(strPath);
CFileFind ff;
BOOL btmp1 = ff.FindFile("data");
if(btmp1)
{
BOOL btmp2 = ff.FindNextFile();
if(!ff.IsDirectory())
{ //*************************//
if(!CreateDirectory(LPCTSTR(strPath+"\\data"), NULL))
{
ff.Close();
return FALSE;
}
}
}
else
{
if(!CreateDirectory(LPCTSTR(strPath+"\\data"), NULL))
{
ff.Close();
return FALSE;
}
}
ff.Close();
return TRUE;
Then I noticed a strange thing. If there is a file in "D:\\temp" named data, the CreateDirectory function after //***// part always fails. Please note that the existing data is a file without extension, not a folder. So I added a line to the //***// part:
CFile::Rename(strPath+"\\data", strPath+"\\data.bak");
then the CreateDirectory function can succeed and the folder data is created. Sadly, I won't be able to change the file data.bak to data anymore because there is a folder with the same name.
How could this happen? Or is it because I missed anything ? Your help will be greatly appreciated.
David

Instead of CFIleFind for Checking existence of Folder or File, why not you use Direct api PathFileExists()

So what are you expecting CreateDirectory() to do when a file named c:\temp\data already exists?

Hi,
Thanks for your answers. I now know the reason I couldn't do that. Thanks anyway.

I've developed a single document application and I use Dialog bars.
I've derived a class from CDialogBar in order to map OnCtlColor and
I use that class as base class.
Then I've derived a class (from my base class)for any dialog bar and
I use its instances in CMainFrame instead of default CDialogBar instance
created by Visual Studio.
I've written a specific class for any dialog bar in order to manage
its events in that class instead of in CMainFrame class.
(Otherwise, having many dialog bars CMainframe class becomes a very
big and complex class).
My problem is the following:
Visual Studio allows me to create methods for any event of my dialog
bar in the specific class but at runtime that methods are never called.
It seems that there is no real association between UI controls and methods
written in my class (and added with class wizard).
All works if I copy that methods and the related MESSAGE_MAP code
in CMainframe class.
Why my classes doesn't catch dialog bars event while CMainframe do it ??
Thanks a lot.

Visual Studio 7.0 I presume? It's full of such bugs and once in a while I think of rolling back to my favorite 6.0.

Is there a way for me to post a windows authentication/login dialog -- get the user to enter his username and password?
I don't want access to this information, I would just like him to re-authenticate himself to me.
I would like to use this to block access to part of my application unless he completes this re-authentication.
Where would I look for this?

Do you really think this is a good idea? Users typicaly don't like to repeat themselves. I think it would be a better design if your application checked the security level/group membership of the logged-in user to determine what features to turn on/off.

Well, David -- thanks for your concern...
But, I'd like to find out how to do this.

Then I suggest you look into LogonUser(). It validates the user name and password and returns True if they are valid.

I need to debug a function defined in a statically linked library attaching to a process compiled with that library. I have two .bsc's, one for the library and one for the .exe. I have tried changing the name of the .lib bsc to the exe .bsc, but doing this way I can't set breakpoints in the function of the library that I need to debug.
|
|

.bsc doesn't have anything to do with debugging. this is the browse information for symbols which Visual studio uses for locating symbol defenitions inside the source code.
To debug what u need is the .pdf file. you have to compile both the library and exe. if the pdb file time stamp is same that of lib, then you can break into the code.
you can chk whther the symbol files loaded correctly by pressing ctrl + alt + u inthe debug mode.
