[RESOLVED] LoadLibrary

[muhammad1992]

I'm trying to use LoadLibrary and GetProcAddress to load functions from a C++ dll. The problem I'm having is I don't know how to actually use the function I've loaded.

Here's some code:

Private Sub Main_Load(sender As Object, e As System.EventArgs) Handles Me.Load
        Dim LibraryHandle As IntPtr = LoadLibrary("C:\instant.dll")
        Dim FunctionHandle As IntPtr = CType(GetProcAddress(CInt(LibraryHandle), "Instant_Dialog"), IntPtr)
    End Sub

So, how do I use the function? Also, I want to add the dll as a resource instead of linking it to the directory, but I get an error when I use, "Me.Resources.Instant.dll")

Any suggestions? Thanks!

Hi,
I don't know much about dll's but it seem easy.
You are putting it in two variables which have a name and a value.
Now you have to sent your variable value to a control or a system object.

Yes, it seems easy, but I don't know how to do it.

This might sound stupid but what is the reason to load the dll
What is the dll its function
why dont you import the dll in the toolbox and then use it

I didn't know I could do that. How can I do that?

[pietercdevries]

right click somewhere in the toolbox click Choose Items
Than go to the com components tab page and hid browse

Ok, well that didn't work very well. I imported the dll, but it doesn't appear in the toolbox. Anyone have any suggestions about my original problem? Using loadlibrary to use functions in a dll?

Someone can only help you if you tell us what you want to do with the dll.
If you baking something and ask how much sugar should I put than someone needs to know what you are baking.
