@Berry - your solution doesn't work, just press the button multiple time and you'll see it Seems to work fine here? Here's a sample debug output when I rapidly click the button. It shows each new thread alternating (the "T1" line followed by a "T2" line) with no misses. The idea...

Is it because of the 3 "UPX" texts replacement in the header, that it's tagged as "corrupt" (malformed and will not execute in a real system)! Removing the 3 x "UPX" texts definitely seems to confuse the anti-virus apps, and it stops lay users from decompressing the ex...

The sleep is just for this example. In my real app, the threads do some processing that takes a while, so the sleep was used here to stop the thread exiting too early and to simulate the further processing.

Okay, this seems to be working for me in the way I need it. I can't see anything wrong with this approach? The goal is to show the time and date, from different threads, each time the button is clicked. Having one single global semaphore doesn't seem to be a problem? I'm not overlooking anything? Se...

This part is always recalculating "height-1" and "width-1" with each loop iteration, which is not optimal: For y=0 To Height -1 ;Loop image height For x = 0 To width - 1 ;Loop image width So do the calculation for them just once, like this: h1 = Height - 1 w1 = width - 1 For y=0 ...

The Semaphore approach isn't going to work for me, because "Global Semaphore.i = CreateSemaphore()" is global and my threads are going to be called more than once, so a global semaphore for a thread is going to send the signal to the wrong thread callers, right?

EXE compressors also sometimes have the opposite effect on anti-virus software: they become suspect. Hmm, not in my experience. Like I said, my apps get several false positives without UPX, and none with UPX. But I also manually replace the 3 x "UPX" text bytes from the file header of the...

@STARGÅTE: Thanks for showing that. I should switch my Delays() to Semaphores() then for my threads? But, can I just use the one semaphore for all my different threads, or does each thread need its own dedicated semaphore? What I mean is, is doing it like this safe? It appears to be. ; Enable thread...

Say what? Yes, it does. I have dozens of read-only files included in my source. Have used them for years.

In both cases the information is passed just as a reference to the thread, and not as a variable or copy. That's why my example has "text$=PeekS(params)" as the first line of the thread: to create a local copy of the params so they're not lost. Sometimes you'll need a small delay after cr...

A simpler alternative if speed isn't an issue: ; Enable thread safety in Compiler Options! Procedure MyThread(params) text$=PeekS(params) n=CountString(text$,",")+1 For i=1 To n p$=StringField(text$,i,",") If p$ Debug p$ EndIf Next EndProcedure text$="1,2,3,4,5" ; Five ...

What type of events? But yes, you can detect mouse clicks, and if it's visible, etc. Not as "events" but you can manually poll for them.

With UPX it's no problem because it's so well-known that every AV just decompresses the exe before scanning.
