Tooltips

[edv-rudrich]

Hi

it seems as if there's a problem with the calculation of the tooltip position when having a
dual monitor environment!
If you use a Laptop with a additional second screen plugged in and you move the application
to the external monitor in the 1-2 monitor mode of windows, the tooltips are always shown
at the Laptop Screen -- not where the mouse is at the external screen.

It also looks to me as if there was a problem when resizing dialogs too in such an environment,
because sometimes my app crashes with an error at DC_Resize() sowhere, but I'm still trying to
figure out what is going on exactly!

And:
2-3 times a days I get the following error:

Michael -

I remember putting code in the tooltip system to prevent it from going off the screen because of user complaints.
I had complaints that a tooltip would display partially off the screen if the object were close to the right perimeter of the screen.

So I changed the code to force the tooltip to anchor to the right margin of the screen.
I can confirm that there is a problem with dual monitors. I just tested it.
I will try to find a solution.

I believe that the Internal Data Structures Corrupted errors have been corrected in build 253.

Give it a try.

This should solve both of your problems.

I tested the tooltips with dual monitors.

Hi ..

Also - copied in the last changes you provided to _dcjdhlp.zip:
No - the tooltip is still not shown on the right position

have to switch back to 252..

too bad, because I have to leave China tomorrow afternoon..

Hi Roger

- Tooltips:

I need to do more testings if can switch to 253 without getting the error posted above..

Thks

Your problem with DC_GetDestroy() is because you are not using the SAVE clause of DCREAD GUI.

I never tested DC_GetDestroy() with an empty GetList and that's why it errored.

The attached _DCGETBX.PRG fixes this problem.

Copy it to your \exp19\source\dclipx directory and run BUILD19.BAT or BUILD19_SL1.BAT to rebuild DCLIPX.DLL.

Hi..

I will try this.. thanks..

Forgot to say:
this code worked for years-- with 252 also..

Yes, I understand that, but DC_GetDestroy() was not doing anything in your code if you didn't use the SAVE clause.
With some new code changes in 253, calling DC_GetDestroy() with an empty Getlist caused an error.
The change I gave you fixes this error. This fix will be in build 254.
