I am seeking advice on why a horizontal-scrollbar (hsb) on a single-row datawindow object does not function.

The datawindow object is long with a width of 9600 because it needs to display over forty columns of data converted to text from a spreadsheet.

The width of the datawindow is 3800.

When run, the length of hsb is about two-thirds of the datawindow's length, but when slid to the far right with the intention to scroll thought the data, the data in the datawindow object shifts only by about a half-a-charcter-width or virtually not at all.

However, if I shift the hsb to the far right and then click in another application, say a Word document that is currently running, the scroll-bar then takes effect and the data immediately scrolls to the end.

Failed to connect to database.

And you are using Powerbuilder 2017 / 2017R2 or an older version?

Hi William,

 

Can you help us with more info on your case:

 

  • What Version/build of PowerBuilder are you using?
  • Is this happening during runtime?
  • Are you using the RichTextEdit Control?
  • Is your application 32 or 64 bits?

 

Regards,

Thanks for your interest.

The client is using a version compiled in Appeon 2017 on a Windows 7 OS.

I'm developing now in R2 on Windows 8.

The problem occurs both in R2 development and 2017 executable modes.

The underlying problem I presume is with the width of the dw object but the slide seems to work if I move it and then change focus by clicking outside the dw. 

So today I'll experiment with code on the lbuttonup event to switch focus.

Sorry Govinda, I omitted to add that it is 32 bit and it is not a rich text edit, simply a type string in a single-row grid dw object, length 3000.

I ended up finding a solution so I apologise for the distraction. 

Nevertheless, someone else may encounter the same problem, so here's my work-around.

I added code to to the 'scrollhorizontal' event of the subject datatwindow (say, dw_1) to change focus to another object, ie 'dw_2.SetFocus()'. 

This worked ok - just like a bought one.
