I tried to download and install the patch for the microsoft foundation classes fo Visual c++ express 2010 but can not seem to make it work

Okay... you might try asking in the MFC forum, here[^]. This is the Mangaged C++ forum. And when you ask there, you might consider including more information. "can not seem to make it work" is not a very helpful description of your problem.

Actually, since this is a configuration question (and not programming)... shouldn't it go to the VisualStudio forum[^]?

You are probably right.

You definitely need to post more information... and be in a more appropriate forum as suggested by Wes.

Visual C++ Express does not include MFC so I am not sure why you are trying to add a patch.

One of these days I'm going to think of a really clever signature.

I just downloaded the "Using managed code in an unmanaged application" from code project. Unfortunately under msvs 2010, when the app is run you get a heap corruption error. Is there someone here who can help out and identify the problem. This is a great example if it worked.

thank you,

Is there something stopping you? I am sure that the author would appreciate someone bringing the code up to VS2010/2012 since the article was written over 6 years ago. Please feel free to correct the code and possbily publish your own article as an update to that one.

Richard,

If this is all you have to contribute, to people asking for assistance, then you should refrain from wasting the bits and space.

You commented that you know nothing about managed C++, as if we can somehow resolve that for you. I was merely suggesting what you need to do if you want to understand the problem you are reporting.

If you want to learn about using unmanaged code then you MUST learn about the many, many ways in which C++ can fail due to pointer problems.

Those are probably the most significant problem that an experienced C++ programmer will face (given that they will have overcome syntax and basic semantic errors.)

An inexperienced programmers will run across them too even though it is based on simple misused of something.

Hi, dear all,

I have a DLL created in C++ in 2008 .NET, it exports a function to be used by many other applications.

Now I have a application also created in C++ in VS2008, I need to call that function from DLL, how can I do it? also the DLL file path is come from my application argument list.

Thanks!

How to activate keys combination with hook ?

Hi
To get the symbol @ for example, I must press two buttons at seem time [Alt Gr] + [button with a and 0 near the backspace button]. So actually my application didn't support keys combination, so when I press this combination I get letter 'a' instead of symbol '@'. I am using VCE 2008. Here is the function I am using :

C++

LRESULT WINAPI EventKey(int nCode, WPARAM wParam, LPARAM lParam)
{
if( (nCode == HC_ACTION) && ( (wParam == WM_SYSKEYDOWN) || (wParam == WM_KEYDOWN) )) 
{
kbdStruct = *((KBDLLHOOKSTRUCT*)lParam);
nChar = getKeyFromvcode(kbdStruct.vkCode, (PWCHAR)&outputChar, (PWCHAR)&deadChar);

if(nChar > 0){/* Record the key*/}

}

return CallNextHookEx(hKeyHook, nCode, wParam, lParam);
}

How can I tell the application to convert keys combinations to its associated letters or symbols ?

Regards

From your code snippet , it seems you are hooking keyboard
to detect your combination you must check virtual key codes for ALT and other keys
check msdn link http://msdn.microsoft.com/en-us/library/ms927178.aspx[^] and also search for key logger on code project
