Can't or won't? Have you searched for WM_DROPFILES or DragQueryFile()? As an added bonus, see here.

I'am just not able because I work in Qt not in api win32. I don't understand how do it (It's 1years what I search).

I have used NtQueryInformationProces, struct PROCESS_BASIC_INFORMATION and struct PEB etc to access process info and then retrieve its arguments. It works great in WIN32 but stops working in WIN64 mainly because of the address space problem. Just be clear I am using 64 bit process to access other 64 bit process's info (its parent process). Can any body provide hint!
Thanks!

I'm curious ... why are you using a deprecated function?
The docs state
"It is best to use the CheckRemoteDebuggerPresent and GetProcessId
functions to obtain this information."

Hi all..
I've a dialog box in which i'm using AnimateWindow. Everything is OK but whenever my dialog Animate(Up to down in may case with the help of)
AnimateWindow(hWnd, 300, AW_SLIDE | AW_VER_NEGATIVE);
My mouse just gets busy if i put on Dialog Box.. I mean busy Icon and i can't click on any of the control inside it..
I know it's refreshing everytime it moves. But how can i overcome this problem..
Thanks all

I don't know anything about AnimateWindow but if it is using the UI thread to do a bunch of processing then you can't click on anything in the UI, period, regardless of what the mouse cursor looks like.

When AnimateWinodw finishes it's processing then it waits for 4 seconds and then pop back. I need to click at the time when it wait for 4 second. I know i can't click anything when it's playing animation. Just need to click when it stops for 4 second...

|
|
Do i need to update or invalidate the Window when animatewindow stops??
I tried that but no success. Can someone throw any light on that??
Thanks..

Hi
Please excuse my english. I'm from germany.
Does anybody know if it's possible to call managed code (c#) from VC++ 6.0? I already found the ManWrap Library, but this library does not work with VC++ 6.0.
I hope somebody knows an alternative.
Thank you very much in advance

Why are you doing it anyways? If you are already using managed code, why not just write the entire thing in managed code?

I know. But in this case this doesn't work. It has to be VC++ 6.0. Not my decision.

This is not really the right forum and I'm not an expert but I think the answer you're looking for is COM InterOp. VC++6 can create and also use COM objects, so can C# through the InterOp library. At worst you'll need to create a separate 'broker' object that's an 'automation' compatible COM object which is written in C++ but CoCreated from the C# side and talks with the rest of your C++ code by COM or whatever means you wish.
C#Class ---> CoCreate functionality in OS ---> automation COM object ---> Your C++ stuff
C#Class <--- InterOp functionality in OS <--- automation COM object <--- Your C++ stuff

Thanks that helped me a lot!
Could i also write the COM object in C#, expose it and call it from VC++ 6.0?

I think that should be possible but I've never done it that way round myself. I'm not sure how you'd do an automation compatible COM object in C# itself but then I'm no C# expert. I guess the guys on the C# forum will know all about it though. Good luck.

Hello,
I am working on a chat application where we enter some text in the edit box.
The text i need to convert it in UTF8 encode. I am able to encode it but there is only one problem that is if the text consist of + or & sign it is not able to convert and the text after + or & sign is omitted.
Please tell me whats the problem.
I am sending the code.

Couldn't you just use WideCharToMultiByte(CP_UTF8, ...)?

What is the type of characters passed to your EncodeToUTF8 method?
You use LPCTSTR as the passed parameter type, which can be a
const char * or a const wchar_t * ... which is it?
If you are going to do specific character set conversions, you need
to use specific char types, not generics.
Here's an example of your EncodeToUTF8() method for a Unicode build
<code>CStringA</code> CChatManager::EncodeToUTF8(LPCTSTR szSource)
{
CStringA utf8str;
#ifdef _UNICODE
int utf8length = ::WideCharToMultiByte(CP_UTF8, 0, szSource, -1, NULL, 0, NULL, NULL);
if (utf8length > 0)
{
char *utf8strchars = utf8str.GetBuffer(utf8length - 1);
::WideCharToMultiByte(CP_UTF8, 0, szSource, -1, utf8strchars, utf8length, NULL, NULL);
utf8str.ReleaseBuffer();
}
#endif
return utf8str;
}
Note I changed the return type to a more specific CStringT type that
is the most appropriate for UTF-8.

Hi,
is there a way to switch off implicit inline,
that is
class ClassOfImplementationNamespace
{
void itsFunc(int x)
{
}
};
should no more give a compiler hint automatically,
to inline this. Something like a #pragma NoImplicitInline?
Thank you,
Werner

There's also #pragma auto_inline(off).

I think it's the compiler option "/Ob0" you want.

Thank you. I'm not quite certain, whether this is, what I want.
What I definitely do not want is to prevent the compiler from inlining. I think it knows best.
What I actually want is to switch that implicit "inline" off, which is automatically associated with the function, although you don't see it, and which is a sweettalk to the compiler to inline the function whatever might be best.

I find these two conditions to be contradictory.
In the first you want the compiler to decide, but in the second you don't want it to be automatic....  
It's probably the compiler option "/Ob1" you want, but you should also have a look at what happens when you're using the keywords for inlining here[^].

In the second I *want* it to be automatic. That's my point. The inline keyword, and I think implicit inline too, means, that you don't let the compiler be automatic but try to tell him what to do. This is what I *don't* want and would like to switch off.
