Re: Win32 API function for getting the hardware details

You could obtain information from the registry such as that under HKEY_LOCAL_MACHINE/System/Enum/, though it may be hard work to do so depending on how much information you want. Though be careful not change anything in the registry!

Setup API is a Win32 API.

Just add:

#include <setupapi.h>
#include <spapidef.h>

#ifdef _MSC_VER
	#pragma comment(lib, "Setupapi.lib")
#endif

It will even work from a console application.

error 0xD0000022 when writing minidump

Hey everybody

I'm trying to write a dump using MiniDumpWriteDump(), the function fails with the error 0xD0000022.

I'm trying to find out what that error means, but I can't find anything about that error code.

Does anyone know what it means?

Thanks!

Did you see this in MSDN?

Return Values
If the function succeeds, the return value is TRUE; otherwise, the return value is FALSE. To retrieve extended error information, call GetLastError. Note that the last error will be an HRESULT value.

If the operation is canceled, the last error code is HRESULT_FROM_WIN32(ERROR_CANCELLED).

Perhaps you should call GetLastError

Hey, thanks!
And yeah, I did saw it...

Finally I found someone who asked about this problem (in another forum).
He said that newer versions of dbghelp.dll must be used (it seems I didn't use the latest version).

More over, that for full dump (what I want), if the OS failed to make a screenshot, it auto-retries and if failed again,
it simply fails the who process.

Alternatively, pause your application from within visual studio (I'm assuming that's your IDE of choice) and add a new watch value of "@err, hr"

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

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

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