Heap corruption

[Denis]

Many thanks to Fred/Freak to write this piece of code (i don't know how has written Procedure _TestHeaps(File$, Line)).
I get a big crash (it close Purebasic , sometimes i have a black screen etc.) with allocateMemory fonction, a wrinting error.

I read deeply the blog issue on heap corruption and step by step i found the problem wich it comes from ma bad coding way

The error is "AllocateMemory heap corrupted"

Just for explanation, i done this. I used a temporary pointer and an another pointer

Code: Select all

Protected *lpIR.IconResource_Groupe
Protected *lpIR_temp.IconImage

I assign the pointers like this :

Code: Select all

*lpIR = AllocateMemory(SizeOf(ICONRESOURCE) + ((*lpIcon\idCount-1)*SizeOf(ICONIMAGE)))
*lpIR_temp = @*lpIR\IconImages

After that, i get icons from exe file with API ressource and i write this

Code: Select all

*lpIR_temp\dwNumBytes = SizeofResource_(hLibrary, hIconInfo)

With your procedure, step by step, i foud that the last line cause the crash
I change SizeofResource_(hLibrary, hIconInfo) by value 100 and it's the same crash, so the problem comes with my pointer... and the way i use it
