Thanks

ozzy, download the fasmw gui package - theres an excellent example in there:

Code:

format PE GUI 4.0
entry start

include '%fasminc%\win32a.inc'

ID_OK              = 101
ID_CANCEL      = 102
ID_CAPTION     = 201
ID_MESSAGE     = 202
ID_ICONERROR           = 301
ID_ICONINFORMATION = 302
ID_ICONQUESTION    = 303
ID_ICONWARNING         = 304
ID_TOPMOST     = 401

I have Fasmw, but this example looks too much confusing to me, I can't understand the ".idata" part and the ".rsrc" part too.... Sad

just sections that organize the code in memory. 'idata' is api imports your program will use. just like in visual basic you would do

Code:

Private Declare Function FindWindow lib "user32" Alias "FindWindowA" (szclass as string, szcaption as string") as long

you do the same in fasm; otherwise windows will have no idea what you mean when calling the api function. the '.rsrc' section is where you defines your resources, like menus and dialogs. fasm has macros to do this in that syntax used in the code, or optionally you can use a resource compiler and create a .res file. again an example of using an external res file is here:

But where can I download a resource compiler, and could you post a complete and simple example of how to display a dialog with a button on it and how to handle the clicks on the button?

Thanks

most good resource compilers cost money, like http://www.sicomponents.com/rbldr.html there are some freeware ones out there, youd have to search around.

that dialog example may seem a bit confusing, but it does exactly what youre describing. it creates a dialog with some radio/option buttons, static labels, text boxes, and command buttons (yes i come from a vb background Smile

)

the example creates a msgbox depending on the options you select, and the text/caption you write.

the code begins by calling DialogBoxParam, which loads the dialog created in the '.rsrc' section. messages sent by windows (mouse clicks, keystrokes, etc) are sent to the DialogProc procedure. the procedure checks to see which message is sent, and performs an action accordingly. when a button is clicked, windows sends a WM_COMMAND message to the DialogProc procedure, which then checks to see which of the 2 buttons was pressed. if cancel was pressed, the program exits. if ok was pressed the program then determines which radio button was pressed, grabs the text from the 2 edit fields, and creates the message box.

ozzy check out http://board.flatassembler.net/topic.php?t=1521 this example, it uses a dialog and handles some messages
