Ah... I think I found it.
System.Net.NetworkInformation

Detect whether or not a network interface or the network itself is up or down? Please let me know. Thanks.

I found the problem... actually my example above wasn't entirely accurate.

"SomeFunction" takes an interface as a parameter, not an object.

This code works below:


IMyObject...

I have a C# function


SomeFunction(out MyObject obj)

When I call this function from Managed C++



MyObject ^mObj = nullptr;

I have two C# .NET projects that are loaded into one application process. Each have a reference to the same common library (let's call this common library the plugin). This plugin library needs...

There are two separate dll Outlook Add-ins we are developing they both require a general library (let's call this library the "plugin") that acts as a proxy for sending/receiving messages across to a...

Thanks everyone

Is there anything that allows me to receive an event if the user changes their windows time zone? Thanks,

FOUND THE PROBLEM!
sizeof operator is the problem and causes a stack corruption.

Incorrect:


TCHAR szClassName[64];
GetClassName(hwnd, szClassName, sizeof(szClassName)-1);...

Thanks, I tried that already but that doesn't help either. It's such a strange problem because when these preprocessor definitions are not defined everything works perfectly fine. This app has...

I wish that were the case. Whoever wrote this program uses "_tstring" eveywhere which when looking at the string header file yields:



#ifdef _UNICODE
typedef wstring _tstring;
#else...

I used the UNICODE preprocessor directive to support UNICODE, however, doing so causes bizarre crashes.

I'd like to know what functions exist within an ActiveX DLL.
What APIs can I use to retrieve this info?

Thanks!

Allocating memory for an object on one thread and deleting it on another thread? I thought that was ok and that thread share heap space?

Maybe this is not the source of the problem and I have...

I was investigating using the ::InterlockedXXX family of functions but how come there isn't a thread safe way to read an int? What should be done if I want to read an int safely? Thank you

I'm using RectangleToScreen to try to find the exact screen coordinates of a control in a form.

Nevermind... I have to call Activate().

I have a window (let's call this window "A") that always needs to be displayed on top of the main application window when "A" is first displayed in the application.
But after "A" is displayed we...

Thanks that's the answer I was looking for.

Thanks, but I thought a pointer was just a variable that held a 4 byte integer memory address. I don't see how casting this back and forth can cause so much problem.

There was a bug that stumped me for a while and I'd like to know the exact reason why this is happening.
I'm going to simplify the problem here.

Ahh... I looked at the code a third time...
I think you are right.

Very good catch! :thumb:

Thank you everyone.

Arjay: I'm 100% positive that DoSomething does not set m_bDoSomething = true.

Why does this occur?
I have a piece of code that looks like the the following:



void MyEvent()
{
if( m_bDoSomething )
{
DoSomething();

Awesome! Thank you, I cannot believe the answer was right under my nose. Still having some problems with this as the events do not get generated but I'm taking a look at the website link you gave...
