Hi! I was for a long time whithout posting. Now I'm back, after learning something about asm programming. And FASM is the best assembler, so time to do some work.

I have a question:
* How to use Win32 API to send text to a program, for example notepad? I need to use some API (I think SendMessage(), don't know...) to do something like SendKeys() does on VB. Something like this:
invoke MySendKeysFunc, the_text
.
.
.
the_text db "Hi! I'm the text that gets written to notepad editbox!',0

Please post some code.
Sorry for my bad english.

Thanks!

yO!

i think, that you should to know, that there is something like "winapi reference". it`s help-file with all functions explained..

anyway.

as you said, there is SendMessage function:

Code:

invoke SendMessage,hwnd,message,wparam,lparam

so, simply:

Code:

invoke SendMessage,window_hwnd,WM_SETTEXT,0,the_text

i think

i`m not winapi master.

Yeah! I know about "winapi reference", I have it. And I also know about SendMessage API and WM_SETTEXT... but the problem is:
I tried to use FindWindow to get the handle to notepad and the use

Code:

invoke SendMessage,window_hwnd,WM_SETTEXT,0,the_text

to send the text... but it change the title of notepad and not the editbox text... So, I need to know how to get the handle of the editbox of notepad... That's my problem... I don't know how to do it!

Any ideas?

Thanks!

I can tell you right now that you will end up having to use some kind of COM interface to do what you want. I'm not sure what the object is you will need but later I can probably find out. I have seen an example of what you want to do being done in many VBScript programs.

I know for a fact also that the ActiveState Perl distrobution includes a script that also does it.

I don't think you can use the standard Win32API SendMessage calls here.

use FindWindowEx for the child. i did not check if the class names were correct:

Code:

hwndnotepad dd ?
hwndedit dd ?

pad db 'Notepad',0
edit db 'edit',0
sz db 0

invoke   FindWindow,pad,sz
mov      [hwndnotepad],eax
invoke   FindWindowEx,hwndnotepad,0,edit,sz
mov      [hwndedit],eax
invoke   SendMessage,[hwndedit],WM_SETTEXT,0,edit
