Retrieving text using a control handle

[Athol]

Hi

I am trying to retrieve text associated with a control using the handle of that control. In the code below, res1 returns some valid text. However, res2 returns the value of ##NOSUCHOBJECT## instead of the same text as returned by res1. Any clues as to what I am doing wrong?

Let>WIN_USEHANDLE=0
GetControlText>XYZ,TCheckBox,1,res1

Let>WIN_USEHANDLE=1
//TCheckBox instance 1 has the focus
GetFocusedObject>hwnd
GetControlText>hwnd,TCheckBox,1,res2

Regards
Athol

I'm not aware of a Macro Scheduler function GetFocusedObject>. That would be the problem in the script you posted.

There might be a way to use LibFunc> and Windows API functions to get a dialog object handle but I'm not aware of an exact function to use.

GetFocusedObject is an undocumented function provided for a specific client, so I'm guessing Athol must be from that organisation.

GetControlText requires a window name and a class name of a child object within that window. The window name must be a parent window. What you're doing is passing in the actual object handle instead of its parent window handle. Hence the difference.

If you have the handle from GetFocusedObject and want to get that object's text use the API function GetWindowText via LibFunc to retrieve the text given the handle. E.g.

Code: Select all

GetFocusedObject>hwnd
LibFunc>user32,GetWindowTextA,gwaRes,hwnd,str,255
MidStr>gwaRes_2,1,gwaRes,theText
MessageModal>theText

That will return the caption text of the focused object, depending on the object in question and whether or not it published a caption property (if you get nothing back it is down to the control and not me).

Now that this has been outed, for everyone else's benefit, GetFocusedObject simply returns the handle of whatever object currently has the focus. I was planning to blog it at some point as a "bonus" function. It was being held over for official release in the next version. At present it is not included in the docs or the code builder, but if you type it into the editor you'll see it is recognised by the syntax highlighter and it also works in the current version! Enjoy.

Looking forward to the blog post for examples of usage... and thanks Marcus for this early Christmas bonus.

Hello,

Can someone tell me if the function GetControlText works in virtual environment, such as remote desktops?

I am using the function to get the text within a ThunderRT6TextBox in a VB6-based form.

Code snippet:

Label>Check_Retry
WIN_USEHANDLE=1
GetControlText>HWND_Form,ThunderRT6TextBox,9,controlTxt

If>controlTxt=##NOSUCHOBJECT##,Check_Retry


The macro worked well before in live environment but seems to go into an eternal loop in the virtual environment during testing due to GetControlText always returning ##NOSUCHOBJECT## despite the class and instance number being correct.

Any suggestions appreciated.
