Thanks too.
But that also does not resolve the problem

Have you looked at LockWindowUpdate? You can only lock one window at a time. Mixing all this with showwindow might do the trick though.

I have a project in wich a want to map many Win32 API Errors to exception classes derived from std::runtime_error. All of these follow one pattern :
class RegCreateKeyExException : public std::runtime_error
{
public:
RegCreateKeyExException(const std::string& message, LONG lErrorCode)
: runtime_error(message)
{
}
LONG getErrorCode() { return m_lErrorCode; }
private:
LONG m_lErrorCode;
};
Whenever i want to create a new class, i have to copy/paste this and just change the name. I was thinking about a way to create a class-template that generates generic exception-classes, but i found no way that wasn't ugly. Then again i'm no template crack, so maybe someone out there has an elegant solution to that problem (or the clear answer that there is none and i can stop searching).

Using VS2005/SP1, writing an MFC application...
I needed to add a call to CoInitialize() in my code, and in the process of adding it, I found something in MSDN that said we should now be using CoInitializeEx() instead, so I did the required #include (it seems you need DCOM to use the new version), and made the call.
Now, when I start up my app, I get the following warning message:
OLE initialization failed. Make sure that the OLE libraries are the correct version.
And the app then starts up.
To avoid the problem, I just went back to using CoInitialize(). Does anyone know what OLE libraries I need that aren't already on a Win2KPro/SP4 box? I though I had DCOM in Win2K...

Did you by chance not do this?
"You must include the #define _WIN32_DCOM preprocessor directive at the beginning of your code to be able to use CoInitializeEx."
Why is common sense not common?

Which concurrency model are you specifying? I don't think you can use COINIT_MULTITHREADED
in an MFC app.

VS2005 (NOT with SP1)/MFC
When I add the OnSysCommand message handler to my app (without adding anything to it), the system menu starts acting weird. The left mouse button no longer displays the menu, and the right mouse button positions it incorrectly. On top of that, I can't resize the main window by click/dragging the border, and I can't move the window.
If I remove the OnSysCommand handler, the app behaves normally.
Has anyone ever seen that? Remember, I'm using the un-patched VS2005 with MFC.
I don't recall that happening in VC6.
--------------------------------------------------
Today
--------------------------------------------------
When I got home from work, I tried the same thing on my machine. At work, we are in the middle of a few projects and will not be applying VS2005 SP1 because that means we'd have to regression test everything we've written in the last year and a half. At home, I don't have those concerns, and I applied SP1 right after it came out.
The original problem described above doesn't appear to occur in an app created in SP1.
Hmmmmm....

I found out what was happening, and posted an article about it.

but i'm stuck when calling the midl myDll.idl /h myDll.idl command? it is said that cannot recognize the midl compiler.
where can get the compiler? is it already installed in the MsDEv?
thx.

Is it a simple dll or an activeX ?
If it is a simple dll, you shouldn't do that but instead simply load the dll and get the addresses of the exported functions (I don't know how VB does to create dlls).
|
|
|
|
|
i think it should be an activex dll. i create the dll by myself for testing. but i got confuse when i try to load it directly from VC++. so i follow the tutorial.. ? any recomendation??

VB can produce only activeX ones.

Hi,
can we use return statement in "?:" conditional ternay operator.
I am using like this (avar == 2)?return:executesomethng(..);
but the compiler is not allowing me do that, and it gives the error C2059(syntax error : 'token').
Regards,
Mushq

Either way, in my opinion you're putting a lot of time and effort to write code that is hard to read and understand, even for yourself if you return to it two months from now.
My suggestion is that you rewrite it: use an ordinary if-statement.

A well written method would have only one return point. The way to do this is,
if (avar != 2)
{
executesomething(..);
}

(avar == 2)?return:executesomethng(..);
err am i missing something here or should this be:
(avar == 2) ? return executesomethng(); : return executesomethngelse();

Actually, I agree that there should be just one return, and the correct syntax for what you're trying would be
return (avar == 2) ? executesomething() : executesomethingelse();
Hope that helps.

I have somewhat of a strange problem. When I create a window for use with D3D the systems appstarting cursor is set in place when really it should be a normal pointer. I do not programaticaly change the cursor in any way. I have tried showing/hiding the cursor from both IDirect3DDevice9 and the standard api, so far I have been unable to change this behaviour.
I could set the cursor myself but why should I?
Another point to note is that I am using the October 2006 SDK on windows vista

Hi!
Is there a good reliable way to determine how much memory is in use by my process?

Mr David Crow has an article about process on the codeproject Im not sure its your answer or no but see it

You need to use a performance counter.
Either do this using code, or use Perfmon.

Let me clarify -- from inside my process.

With performance counter he can see a lot of detaily of his process(Working set/handle/thread/priority,Mem usage ,...);)
