Hi
I had task pane manager with 10 items all correctly linked to existing task pane files etc. I was hoping to copy controls from an existing windows form to a new task pane and then delete the existing form.
So, in design-time I dragged three controls from the existing form to the new pane. I copied the form's code to the pane's code area at the bottom after the initialise event, commenting it out to prevent problems. I then deleted the form.
Now I cannot assign a taskpaneclassname to any existing taskpanecollectionitems, nor can I create a new collection item. This error message will not go away.
I have checked the filename links and have no errors or warnings.
Any ideas - thanks for your help! |

Hello Tom,
Make sure the old task pane files are actually deleted and try to restart Visual Studio.

Thanks Andrei
I have checked: each remaining pane in my project has 3 files you would expect, with .vb, .resx and .Designer extensions. The deleted files were successfully deleted from the project folder.
Restarting VS has no effect, and I have checked creating a new fresh project works ok with no error message when I add task pane to manager.
The only thing I can think of is, when I dragged controls from an older windows form to a new task pane (design areas), did this cause the GUIDs of each to get confused or not be consistent with each other?
I'm hoping there's an obvious answer, I don't really want to have to delete my task panes manager then recreate it all again particularly if there is no reason why it happened in the first place.
Hoping you can help !

Hello Tom,
When specifying the pane class, you have to specify both namespace and class name e.g.the TaskPaneClassName property would be "MyAddin24.ADXExcelTaskPane1". I assume the class name hasn't changed after copying it but the namespace has changed because this is a different project with a different Root Namespace! So if I copy these 3 files to another project, say MyAddin25, the namespace would be different and the TaskPaneClassName would need to hold "MyAddin24.ADXExcelTaskPane1"!
To All,
This is about VB.NET, not C#.

Hi Andrei
That would make sense, but the form was already sitting in the same namespace as the pane (both have been existing in the same project).
I only have one project. I haven't copied the form class, I have just dragged controls from the form to the pane class.
I then deleted the form class from the project.
No matter, I am going to have to see when my last functioning backup was and try again...... |
