Getting text from Delphi TPanel object

Jerry Thomas · Post by **Jerry Thomas** » Fri Nov 12, 2010 5:00 pm

Our app is Delphi based and uses TPanel class displays for a lot of the numeric data.

I have tried the usual ways of getting text: GetControlText, GetTextAtPoint, GetTextInRect, GetWindowText, GetWindowTextEx.
These work where we have 'regular' text but not on the TPanels.

Here is a snippet from the System Windows tool
330770 - TGroupBox "Nozzle Position"
- 724926 - TPanel " -6.375"
- 1380106 - TPanel " 1.275"

I can get the TGroupBox label but not the TPanels.
GetControlText>OMAX*,TPanel,1,strText

strText is blank

I wrote a screen capture and compare routine to read one character at a time. The problem is, depending on the application mode and the OS, I have several possible 'styles' (yellow, green, red, and WinXP displays differently than Win7!). I am trying to not have 6 different sets of characters to compare against.

I have tried a couple of different OCR tools, with no luck.

Any suggestions?

GetWindowTextEx, GetTextInRect and GetTextAtPoint should all work with Delphi TPanel objects.

None of those work.
I have used the Sample Text Capture script and tried my own.
I can get other text but not from the TPanels.

Has anyone eventually managed to find a way to scrape data from a TPanel? Running into the same problem over here.

Thanks

My problem turned out to be using the wrong Window.
Instead of the parent window title, I needed to use the section title.

MS's System Windows tool will show what you should use.
