How to use ComboBox and GetClipboard

[Blue]

Hi all,

I gotta stuck in an assembly project, I need to do two thing in it.

First one is I am using a combo box in it, so I need to know that how to use combo box to add lists in it, and how to get that which one is selected ? Also I want to get the selected list value from Combo box in Digits like, I want to prepare combo box list like this :

1. XXXXX

2. YYYYY

3. ZZZZZ

And want to take selected value back in Numeric form like 1,2 and 3.

The second question is that, how to get the clipboard data in a temp buffer.

I tried the following code, but it's giving me waste

local ClipHwnd:DWORD
Invoke OpenClipboard,NULL
 .If eax
 invoke GetClipboardData, CF_TEXT
  .If eax != 0
   invoke GlobalLock, eax
  mov  ClipHwnd, eax
 ; Do something with clipboard text here!
; ClipHwnd == pointer to text
  invoke GlobalUnlock, ClipHwnd
  .endif
 invoke CloseClipboard
 .endif

I taken this code from winasm forum, where xsp!der told that using edx instead of ClipHwnd solves the matter, but in my case. It is not working.

Ref : http://www.winasm.net/forum/index.php?showtopic=3676

Please help in solving this problem.

1. CB_ADDSTRING + CB_GETCURSEL

2. ClipHWnd will hold the address of the text, just strcpy it somewhere and thats it

For extra safety you might want to call IsClipboardFormatAvailable(CF_TEXT) before trying to get the text

1) MASM32 example: http://members.a1.net/ranmasaotome/masm32/Combobox.zip

2) Your clipboard code is buggy in several ways. Try this one:

    local ClipHwnd : DWORD
    local Buffer[4096] : BYTE    Invoke OpenClipboard,NULL
    .If eax
        invoke GetClipboardData, CF_TEXT
        .If eax != 0
            mov ClipHwnd, eax
            invoke GlobalLock, eax
            ; If you want to have the text to be available after calling 
            ; GlobalUnlock and CloseClipboard, you MUST copy it to your own buffer
            invoke lstrcpy, ADDR Buffer, eax
            invoke MessageBox, 0, ADDR Buffer, 0, 0
            invoke GlobalUnlock, ClipHwnd
        .endif
        invoke CloseClipboard
    .endif

Warning - My code does not check for string length, so buffer overflow will happen, if there's more than 4096 characters in clipboard.

CB_GETCURSEL

add 1 to the return value and you have your number 1, 2, or 3

Thank you so much Killboy, now I can proceed with project.

Thanks

Next time state the prog lang in a tag [MASM] in the title so people (like me, i thought it was a Delphi Q) won't get confused.

Given that his post contains an MASM example, its fairly easy to tell what language its in. You'd know that if you were a programmer and didn't just copy everyone elses work.

If you don't have anything clever to say, don't reply at all Wiccaan.

I doubt the only thing you can make is a trainer, can't wait for your next tutorial on how to use Debugging APIs.

Oh, btw, i said in the Title of the thread, not in the content of it, saves time from getting inside here and see if it's something else, read before you reply, you're such a "programmer", i don't want to tell you how some of the CEF legends talk about you in the back.
