Hi - I wonder if anybody else can confirm the same issue I'm having.
Using Delphi XE, latest AddInExpress (December 2012 release, premium) and latest DevExpress (12.2.2) I am trying to use a cxGrid on a task pane in an Excel Addin.
If I just drop the cxGrid on its own, all is fine. But obviously it's of no value until I can add some columns - and as soon as I do that the application bombs out (message below).
This is with Office 2010. I get the same problem with Office 2003 and earlier versions of DevExpress and ADX in Delphi XE, but no problems with Delphi 7.
It's quite easy to replicate on any new addin, just do an Excel app with a single enabled task pane, and add a cxGrid to the pane. It will look fine. Then add a column to the grid and try it again - it will error.
Log is:
Exceptions:
============
ADX Extensions error (TadxExcelTaskPane.CreateEx): the add-in has fired an exception.
Access violation at address 07C67119 in module 'BOEExcelToPDS.dll'. Read of address 00000000

Hello Richard,
Below is what a customer reported about an issue with cxGrid:
===
There is no code executing when I scroll. I found out what caused the problem. It is the column HeaderGlyph. If I clear it, the add-in works fine on Windows 7. Otherwise it gives the AV error.
===
Can you please check if the above info applies to your case as well?

Thanks for the reply Andrei.
I have no headerglyph set for any column.
When I first add the grid, all is fine.
As soon as I add a column - even if I don't set a single property, or connect it to a field - it will AV.
Regards
Richard |

Richard,
Pleasy try to modify your add-in as shown below:
initialization
TadxFactory.Create(ComServer, TADX_Outlook, CLASS_ADX_Outlook, TAddInModule);
// init
dxInitializeGDIPlus(); // uses dxGDIPlusAPI !
finalization
// unload
dxFinalizeGDIPlus();
If this doesn't help, I suggest that you contact the DevExpress team.

Andrei, thank you very much, that has indeed fixed the problem.
For future reference, the commands have changed slightly, as per this DevExpress entry:
http://www.devexpress.com/Support/Center/p/B199204.aspx
(Add "dxCore" to your uses clause, then use dxInitialize and dxFinalize)
Regards, and thank you again
