Need some Tips for this keygen template I made

Hi guys,

I'll start by saying I don't have much experience with WinApi. I'd like to show you the code for my keygen template. Any suggestions or improvements are welcome.

I'm currently unable to set transparency in edit texts. If anyone knows how to do this without forcing redrawing using invalidateRect, I'd be very grateful.

I also wanted to point out that I used LLMs because I couldn't find much online about managing transparency in edit texts.

Thanks in advance, hacktooth.

your code seems to run fine...

edittext transparency commented out (can clearly see the edittext control)

original code not commented out (looks like the form.bmp (as ripped from the supplied exe))

    I commented out that portion of code because transparency works correctly,
    but if you look closely, it generates artifacts, especially when selecting text.
    However, I solved the problem just last night by looking at some templates on the forum in asm x86 and making the appropriate changes.

    Below, I show all the updated code.
