The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Using native MFC DLL from .Net application using VB.Net or C#.Net

Asked by m_kristofer in .Net Compact Framework, Microsoft Visual C++.Net, Microsoft Visual C#.Net

Tags: .Net, native Dll

Hi guys.. I've been googling the solution for my problem all day but I could not find the answer may be you could help me.

How can I access the classes and methods on my native MFC DLL from my .Net application?
I already tried the LoadLibrary, GetProcAddress, Marshal and DynamicInvoke() but I could not make it work. Even using the Alias it didn't work either. When I tried using SetWindowTextA in alias it worked but when I changed it with my dll something is wrong.

What could be the best way to access my native dll from .Net application?

my native MFC DLL is a Regular DLL with MFC statically linked dll type.

The code below didn't work with my dll and even in kernel32.dll but works with user32.dll

             Declare Function SetWindowText Lib "user32" Alias "SetWindowTextA" (ByVal hwnd As IntPtr, ByVal lpString As String) As Long
 
method(){       
 ret = Marshal.GetDelegateForFunctionPointer( _
                      MethodPointer, DelegateFunctionType _
                      ).DynamicInvoke(arg)
}
