CString has an overloaded = operator for VARIANT type so long as the variant is filled with BSTR data (ie what you would get from ADO) so you could do this:
VARIANT vt;<br />
CString str; <br />
<br />
<br />
str=vt;<br />

Does this make sense?
When I enable breakpoints, the code at the breakpoints gets executed and things appear to work as expected.
When I DON’T ENABLE breakpoints, the code at the breakpoints DOES NOT get executed.
It doesn’t make sense that enabling/disabling breakpoints would control if a piece of code is reached or not.
I'm debugging an MFC app I created in VS2005. I am running the DEBUG version and attaching to the process.
When I disable the breakpoints, nothing happens (I have used message boxes/print statements in place of breaks to see if code reached.)

It could be possible that message boxes are unable to be created. Why don't you instead try using OutputDebugString()? Are you sure this is not a problem with Debug/Release builds?

Is there any way to hide a process (not window) from the windows task manager?

Why would you want to do something like that? One suspects for evil purposes...

No because maybe you can to hide it of Task Manager but other programs can to see it.

I just jumped into this project, for years the rule was "never delete a line of code". You can imagine the mess and how hard it can be to find the "right" function actually called for a task.
Does anyone know of a tool that will list me all classes, members, functions, struct, etc... that are NOT called or used by anyone else? Something like a linker option perhaps? Project is compiled under Visual Studio 2003.
I tried a few code mapping tools, but with 600K+ lines of code, thousands of classes and fucntions in hundreds of libraries, I need a black-list not a withe-list to compare too.
Thanks,
AFN

You could try using Visual Assist from www.wholetomato.com

Hi everybody;
When I try to create a new project (c#,c++ etc.) on Microsoft Visual Studio Professional edition, I got this error message "Requested registry access is not allowed!" and creation of new project fails.
My OS is Windows Vista Home Basic. This problem appeared recently but I cannot fix it.
What can I do? Any suggestions?
Thanx everybody for reading...

Are you running VS as an administrator?

Yes my friend, I also try it!
I make a bit research in Registry for example under HKEY_CLASSES_ROOT some key start with ._sln* are not accessable. Maybe it is a clue?

Thanks for putting up with my many queries.
I have reached this stage:
// wn = the handle of the current window
#define OUCH MB_ICONEXCLAMATION
HDC dc=GetDC(wn); HDC dc2=CreateCompatibleDC(dc);
char t[256]; BITMAP bm;
.... // Here I set the elements of bm
sprintf(t,"%d: %d * %d, width = %d, %d planes, bpp = %d, pixels at %d",
bm.bmType,bm.bmWidth,bm.bmHeight,bm.bmWidthBytes,bm.bmPlanes,bm.bmBitsPixel,int(bm.bmBits));
MessageBox(0,t,"set up hbm",OUCH);
// This displays 0, 600, 600, 1800, 1, 24, 28180544 :: all correct as far as I can see;
// here 28180544 pointed to the pixel array of a valid image (a CGI image of two frogmen)
HBITMAP hbm=CreateBitmapIndirect(&bm);
BITMAP bm3; GetObject(hbm,sizeof(BITMAP),(void*)(&bm3));
sprintf(t,"bm3 is type %d, %d * %d, each row %d bytes, %d planes, bpp=%d, pixels at %d",
bm3.bmType,bm3.bmWidth,bm3.bmHeight,bm3.bmWidthBytes,bm3.bmPlanes,bm3.bmBitsPixel,int(bm3.bmBits)); MessageBox(0,t,"size",OUCH);
// This displays 0, 600, 600, 1800, 1, 24, 0
Please, what happened to my image's pixel array or its address?

You're only guaranteed to get a pointer to the pixel bits with a DIBSection.

At last, thanks, it works, and I duly got my image back with "The quick brown fox jumps over the lazy dog." written on it, as a text run.

I am trying to cache icons but when I store the HICON, the second time around, I get no icon. I think I need to copy the data referred to by the HICON into my cache rather than store the actual handle. How would I copy the data?

I answered my own question, CopyIcon does the trick!

Hi.
I have created a console application which reads a file from the local disk and does certain operation on the data. where i need to specify the path of the file.
Now i have to create a dll file and i have to pass the path of the file as a parameter to the dll, But if i declare CString to hold the path it gives an error : undeclared identifier / no such directory of files found.
please help me asap.

did you include <afx.h>
and by the way you shouldn't be using a CString variable to be passed as a parameter. better use BSTR
Somethings seem HARD to do, until we know how to do them.

I tried using BSTR but it is giving error in header file. can anyone suggest the solution, its very urgent..
