how 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++ .

Can I make a DLL in VB.NET which I can use in VB.NET with the tag DllImport just like we import functions from "user32.dll"?
View 2 Replies[DllImport("odbc32.dll")] it is working well with 32 bit environment( os) but using 64 bit it is not working. Is there any odbc64.dll? I tried it but dllnotfoundexception was found. So does it has any other name. How to import it? how to use this dll or both in same application.

Private Shared Sub DwmEnableBlurBehindWindow(ByVal hwnd As IntPtr, ByRef blurBehind As DWM_BLURBEHIND)
End Sub
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.
