View 2 Replieshow should I DLLImport thing in VB.NET?Example would be:
<DllImport("user32.dll", SetLastError:=True, CharSet:=CharSet.Auto)> _
Private Shared Function GetWindowText(ByVal hwnd As IntPtr, ByVal lpString As StringBuilder, ByVal cch As Integer) As Integer End Function
If I put it inside a Class or somewhere else, I get "DLLimport is not defined" I am using VS2008 (pro)
The code snippet below is from a c# class library Moserware.Skills.dll that I would like to use in my VB.Net project.I understand that I need to use Dllimport to gain access to the TwoPlayerTrueSkillCalculator class and specifically the CalculateNewRating() function.[code]
View 5 RepliesI have an unmanaged C++ dll that I am using in my program. I have successfully used several functions using DllImport. I have run into a problem with one function that takes a structure as input. I originally tried building a structure to pass to the function, but this was unsucessful. So i created a class to define the needed structure. When I pass this, I get no error message, but also no data is passed back to this variable. I have a C++ example of how to use this function, but I don't know how this translates to VB 2005. Here is how they call it in C++ .

Is there a way to only load this if it is present? Only Vista/7 has this DLL generally, and if a program references it in XP there is an error.
I notice in the MSDN documentation that there are multiple ways to declare a reference to a function in an external DLL from within a VB.NET program. The confusing thing is that MSDN claims that you can only use the DllImportAttribute class with Shared Function prototypes "in rare cases", but I couldn't find the explanation for this statement, while you can simply use the Declare keyword instead.

View 3 RepliesA few years ago I have been busy creating this application but it didn't succeed, now Im coming back to it and similar problems occur. Basically I use SetPixel on a given window to draw a line, work fine, but the line goes away as the window redraws itself.The problem: I have been putting timers and threads on it to make sure the line is being drawn. Is there any way to make a loop to make a certain thing happen about 10-30 times without taking in too much memory/CPU?
