See JwaWinBase::CreateMutexA/W But I tried it again in Delphi 7 and you know: I had the same problem. It seems that at the times Marcel created the patch, LongBool was the correct way to solve this problem (Maybe < D5). However I changed the declaration of the wrapper function from LongBool to DWORD (to remain the size of the boolean parameter (4)). And now it works. <strong>The fix was applied to trunk revision 760.</strong> A long time ago the CreateMutex issue was fixed by Marcel. See JwaWinBase::CreateMutexA/W

It should be -1. I fixed that issue. Thanks. Originally I wanted to add the Boolean type at first, then I forgot it. Now I readded and fixed it. No, you’re right. It should be -1. I fixed that issue.

BOOL/LongBool value := true; mov [value],$ffffffff And in Summary you say that "BOOL in Delphi" is "LongBool" and True is "1". First you say True is -1 and then you say True is 1. Is this some kind of mistake or I just don't understand something? I don’t get it.

BOOL/LongBool
value := true;
mov [value],$ffffffff

And in Summary you say that “BOOL in Delphi” is “LongBool” and True is “1″.

First you say True is -1 and then you say True is 1.

Is this some kind of mistake or I just don’t understand something?
