Hello everyone,

I am writing a managed console application which will invoke native C++ COM DLL on Windows Server 2003 x64 using PIA interop. The managed console application is built for "Mixed Platform" debug version and the native COM DLL is built for x64 debug version. I am using interop to invoke method from managed code which are exposed from COM code.

I find creating a COM coclass object in managed code is ok, and it is also ok to call some methods of COM coclass from managed code using the created coclass object instance. But when I call into a specific method Abc (Abc is implemented/exposed in COM DLL) from my managed code (FooImpl.dll), there is exception like this, I am so confused that I did not write any method called "XmlSerializers". Any ideas to debug further?

(FooImpl is my managed code DLL which will call COM native code, my managed code console application linked with FooImpl.dll.)

--------------------
An unhandled exception of type 'System.IO.FileNotFoundException' occurred in FooImpl.dll
Additional information: Could not load file or assembly 'FooImpl.XmlSerializers, Version=1.0.1121.1, Culture=neutral, PublicKeyToken=null' or one of its dependencies.

The system cannot find the file specified.
--------------------

regards,
George

It seems you dont have the file and it refers to it.

Thanks Hamid,

I finally found the root cause is, the application is built for mixed platforms and the DLL is built for x64. When I change them both to x64, it is fine. Smile | :)

George

Transparent colour on window using win32

Hi,

If I wanted to have a window that was a custom shape, e.g. a circle, how could I make the regions of the window that I do not want to see transparent?

|-------------|
|---/     \---|
|--|       |--|
|--|       |--|
|---\     /---|
|-------------|

Lame diagram, but I would like to make the areas composed of dashes transparent so that only the circular area of the window remains visible.

Thanks

Try SetWindowRgn[^] - there's an MFC variant[^]

An alternative to using window regions is to use layered windows[^].

THERE IS NO NEED TO SHOUT AT HIM.

You said "failing".

But imagine you go to the doctor, and say "I am ill", and then say nothing else. Do you expect him to give you a cure for cancer?
Or when he says "Oh dear, that must be bad. What are your symptoms", you reply "I AM ILL"?

IN WHAT WAY is it failing?

Have you tried stepping into the CStdioFile::WriteFile yourself, and tracking your string to see where it goes wrong?

This is what I used in a project few days ago:

std::basic_string<TCHAR> sFileContent = _T("");

if (sizeof(TCHAR) > 1) // if wide char
sFileContent += 0xFEFF; // this header tells notepad to read file as Unicode

sFileContent += _T("My favorite Dave Attell quote: ");
sFileContent += _T("Yeah, I know, some people are against drunk driving, ");
sFileContent += _T("and I call those people 'the cops'. But you know, ");
sFileContent += _T("sometimes, you've just got no choice; those kids gotta get to school!");

// save to file routine
