Frederik,
sure you're right, but not in one fact. ( this one I.J wanted to know )
As soon as you inherit from any Component, the studio tries to open it in a designer editor. That is a default behaviour of the visual studio.
If you double click a file in the solution explorer, then a designer opens.
So it's really annoying if you always get such strange designer for classes that are just inherited from a Component, but do not contain any visible things.
The only thing that really helped me out, was to set this attribute:[System.ComponentModel.DesignerCategory("")]
I didn't knew this =) so cool hint !
I just get a problem with partial MainForm classes. Then it yells "duplicate attribute"...
Does here anybody knows a solution to avoid in some partial class-files the designer to be opened on double click ( without the duplicate attribute error on compile ? )
I think I found a small bug, in VS2005...
By setting the DesignerCategory-Attribute on the partial form class, on save the solution explorer shows up an icon, identifying the file as a c# file (no form).
Then I put a comment (//) before the attribute - and it keeps opening the file in code view. Also after closing and reopening it's stored internally as a non designable form-part.
Even on re opening the complete solution.
So I think there is any information in the solution or project file...
... I found this in the .csproj file:
...
<Compile Include="GUI\VFormMain_Test.cs">
</Compile>
<Compile Include="GUI\VFormMain_Theme.cs">
</Compile>
<Compile Include="Core\VTTEnv.cs" />
<Compile Include="GUI\VFormMain.cs">
<SubType>form</SubType>
</Compile>
...
Studio updates from time to time - then it updated the form files again (doh)... ok.. but there is probably a workaround to avoid this.

last edit...
found something:

( name the file you want to open without designer into .Designer.cs )
( Yes you have to name something to switch it of LOL )
Seems to work.
