Beginner questions / Importing a function from a DL...
Last post by jm - June 27, 2026, 07:50:22 PMThis is purely a research exercise on my part with limited knowledge. I'd be grateful if someone could tell me if there's a way in which I can import a function from a Windows DLL that I created using a non-C language compiler on Windows.
The other language compiler has understandably given me only a .DLL and a .LIB but the examples I've seen, where a DLL is used within C, appear to show a .H header is needed. What should I create in the .H file, or is there another way?
The DLL I created is called JDL.DLL and it contains a function called myfunction() to accept a float value and return the result also as a float. Can anyone help with this please, thanks.

Work in progress / Re: New Task Schedule 2.0 exam...
Last post by John Z - June 26, 2026, 04:23:26 AMHere is plain C working code to schedule a task. It is implemented in my upcoming version of the calendar which already has a vbs task scheduler and a powershell task scheduler, now has a C task scheduler...covering my basis 
I like to mention that it uses TimoVJL's Variant setup (which I did not know how to do) THANKS Timo!
Example inputs are also provided within the code at various places. Look for //EX:
Source code attached . . .
It is a complete working 'one time' scheduler, just created the names structure and fill in that should be most all of the work.
If needing a daily or some repeated schedule look at TimoVJL's code near the top of this stream, he's done it.

Very informative. I had no idea that 5GigHz was the max turbo speed of my 'travel laptop'.
Windows only reports the leisurely 1.7GHz.
A very tiny, partial sample, of one of the output sections of the program to spark interest.

Last post by Pelle - June 18, 2026, 10:21:11 PMNothing fancy, just a program I wrote last year to dump info about my BIOS settings (to the console).
Incomplete in many ways. Maybe useful to someone...?

Assembly discussions / Re: Combining object files
Last post by Pelle - June 18, 2026, 08:37:54 PMOK. I still don't see the point in having a tool that combines object files, but never mind. Not important.

Last post by Vortex - June 14, 2026, 09:43:31 PMHi Pelle,
The purpose of merging object modules is to provide only one monolytic object file to the linker. Nothing fancy. As you said, it's preferable to create a static library.
