Dear John,

Following things I've noticed when coding Find/Replace dialogs:
1. Libraries are not easy to use in other projects than Fresh:
- they depend on each other, so in most cases you need to use most of them
- they use variables such as 'hMainWin', 'hInstance', etc so your code won't work when you will be using 'hinstance' or 'mainhwnd' for example. (I know that this problem is difficult to solve, and proably it won't be solved, but at least some note about it in documentation would be nice Smile)
2. File 'msgloop.asm' contains application termination code. IMO it should be moved because it may create some problems in some other apps, where user will have his own termination code.
3. bugs with modal dialog boxes:
- when user clicks on 'x' instead of closing a dialog with buttons, dialog's parent window doean't get focused.
- they don't handle the keyboard input properly (I mentioned that in a post with Find/Replace dialogs)

Proably you know about most of these, but I was supposed to find the 'unclear points' of the library, so I wrote what I've noticed, and I'll write more if I'll find something else Very HappyVery HappyVery Happy

However, form.asm is a great and easy to use library, you've made a REALLY GOOD work Very Happy.

regards,
decard

Hi decard.
Well, you are right for most things. I am working hard on these libs now. Mainly on dependencies. I think there will be some (good) solution with these global variables. Smile

Regards.

That's good Very Happy

btw, I've got one question about form.asm: to do my find and replace dialogs, I would need to provide custom window proc to those dialogs. To do this, I would need to subclass the form class, right?

On the last question: Actually no.
When create the window of class "Form" you must set the last parameter of CreateWindowEx (I can't remember the exact name) to the address of the Message procedure. This procedure have arguments like normal WinProc, but you only process the messages you want. You have not to care about another messages. If you process the message simply return the result in eax and clear carry flag. If you don't process the message simply set carry flag and return. You don't have to preserve any registers in this procedure.

See: Project manager window procedure for details. If you see that I preserve some registers, this is an error and should be fixed. Wink

Regards.
