Retrieving info from an Edit Control

[Bruce Wood]

Hi Brain Trust:

This info is from WinBatch Analysis Program. (Truncated)

It displays Top and Child windows and all controls.

I need to get the info from the Edit Box #27.

Can someone please post PB/DLL 6.0 code to retrieve the infomation.

Can it be retrieved by name and/or class as well as IDENT?

Does the same code work with ComboBox/ListBox also?

Thanks

Assuming the edit control responds like a normal edit controls (ie, it is not a proprietary custom control), then check out GetWindowText()... you'll need the handle to the edit control. If it is a dialog, then you can get the handle with GetDlgItem(). To get the handle of the parent window, check out FindWindow() or EnumWindows().

Disclaimer, I cannot remember if GetWindowText() works across process boundaries. (I'm away from any manuals and notes right now).

Lance:

WinBatch can retrieve the Info, but I need to do the operation from a DLL.

The process is no under my control and I also read somewhere that
GetWindowText does not work across processes..(Come on)

GetDlgItem does not seems to work, but I am a beginner in this so
I may not be calling the API correctly.

What are the correct values:

Declare Function GetDlgItemText LIB "USER32.DLL" ALIAS "GetDlgItemTextA" (BYVAL hDlg AS LONG, BYVAL nIDDlgItem AS LONG, lpString AS ASCIIZ, BYVAL nMaxCount AS LONG) AS LONG

I am assuming that Ident - 6530 is the nIDDlgItem AS LONG "Parm"

How do I get the drilled down handle for the BYVAL hDlg AS LONG "Parm" ?

Thanks

I am posting the display again because it seems to have lost its formatting.

Guys:

The display is not formating properly.

I can't seem to get the display to post formatted correctly.

The First 1 is the Top
The second 1 is CHILD 1
The Third 1 and on down are under Child3

The format sure good correct as I'm posting.

Sorry I am a Novice poster.

It does appear that the Edit control ID is the "ident" value.

Since you are writing a DLL, is it being loaded into the Process that owns the windows/dialogs?

PS: The "#32770" window class and the reformatted table indicates there is a parent dialog, with a child dialog containing controls.

You'll need to get the window handle of the control with the ID 6530. This control's parent window is "Child2".

So, in pseudocode, this would be something like this:

hWndEdit = GetDlgItem(hChild2, 6530)

Does "Child2" have a unique title/caption (as a child control, the text is probably not displayed, but a SPY utility may help you here.

Otherwise, use EnumWindows() to get the handle to "Parent", then use EnumChildWindows() to dig down until you identify the edit control with the ID 6530.

For example code for EnumWindows and EnumChildWindows, search the BBS for those keywords - you should find some code here somewhere.

Lance:

Not luck. I really need a small example program on

getting parent handle,drilling down to child(s) and getting

controlID handle.

Can anyone else help?

Thanks

unfortunately, i (personally) do not often have the time availlable to write example code on demand, but the information you need can be found on this bbs, in the win32.hlp file, and in http://msdn.microsoft.com

a quick search for "enumchildwindows" gives a good example of using enumwindows() at http://www.powerbasic.com/support/pb...ad.php?t=17377 - this should help you find the parent window handle.

using enumchildwindows() is basically the same... you just need to use getdlgctrlid() on each child window handle in the enumproc to test it's id number matches the one you want.

another sample i posted a while ago may be of help. it looks for
running pbedit and its combobox, after which it widens the dropdown.
just change looking for pbedit to whatever and same with the combo.
look for textbox class instead (if dialog has only one textbox).
see: http://www.powerbasic.com/support/pb...ad.php?t=22983

btw, i have lifted text out from other app's using this method, so
seems like getwindowtext can work across "boundaries"..
