I am new to Xojo and looking for some help in regards to windows dll files. I am very proficient with AutoHotKey and migrating into Xojo. It’s easy enough when working with dll calls in AHK but Xojo has a different way to go about it and looking to understand how.
I created a simple dll using PureBasic and looking to call a function from the dll and needed to understand on how to go about implementing that within Xojo.
It’s a simple dll with 2 functions: TaskbarShow and TaskBarHide
I wanted to create a simple button when pressed just calls the function. There is nothing that needs to get passed to the function.
Any help such as an example of code that I would use would be appreciated and understanding windows dll function calls.
I have a feeling it’s pretty simple using declare statement and some form of a call to that function but just not sure without seeing an example to better undertstand and know the correct way for future.
There’s quite a few snippets of windows declares around the forum, if they’ve been done already you can usually find them by putting their win32 call into search.
If you need a website to look up the types for conversion, take a look here [LINK REMOVED PER OP REQUEST]
Your right, declares can access the functions within dll using Xojo. Just a few questions before we go down the path of creating a declare:
When the dll was created, are the functions exposed - meaning can other languages access the dll?
Did dll creation keep the naming convention of the functions - sometimes function names get mangled and a function like HelloWorld will get changed to something like Helkei3984kjdf, which doesn’t resemble the original function name.
If the answers are all ‘yes’, then we can give it a try!
What are the function names, parameters, and return types within your dll?
Here are a few resources that exist for Xojo Declares that I can easily remember
