Browse listbox column sorting does not work in remote computer

questions

Hi,
I am using Clarion 11.1.0.13855.
I have column sorting enabled on some browses and it works perfectly on my development computer. When I move it to a remote VPS the columns sorting doesn’t work. No crashes. it just ignores my click on the column header. This occurs when using MS RDP and with TS-Plus. In fact if the statement “IsTermServer() = True” then the columns sorting fails to work.

Has anybody come across this and found a fix?
Thanks and regards,

Mark

Did you rule out a left/right click transposition?

Hi Jeff,

I tried that but it just brought up the Add, Edit, Delete context menu. The problem happens when I either deliver the app via a browser using TS-Plus, or when using RDP to access the app in the remote machine.

Quite odd I think!

If that same menu does not show up when you are not in RDP, then that could be a clue.

I wonder if there is a difference in the value returned by PROPList:MouseDownZone and PROPList:MouseDownRow when run on RDP vs Local.

Could be a UDP issue.

Terminal Server(TS) / RDP for ever has had various problems when UDP is used.

UDP is quick but packets sometimes get lost.
TDP is slower but packets dont get lost, because they are resent.

To test on the client machine:

reg add "HKLM\software\policies\microsoft\windows nt\Terminal Services\Client" /v fClientDisableUDP /d 1 /t REG_DWORD

On the server, disable using UDP, something like this might work.
