I recently registered and downloaded the API files.
I imported the project into C# 2008.

When trying to preview the design view of a few of the forms I get the following error:


Object reference not set to an instance of an object.

at OEC.API.Example.OrderDraftControl.PrepareControlEventHandlers() in C:\_Accurate\OpenECry\OEC API Example\OrderDraftControl.cs:line 32
at OEC.API.Example.BaseControl..ctor() in C:\_Accurate\OpenECry\OEC API Example\BaseControl.cs:line 34
at OEC.API.Example.OrderDraftControl..ctor() in C:\_Accurate\OpenECry\OEC API Example\OrderDraftControl.cs:line 21



I can't find any issues with the code on those lines. The controls OrderDraftControl & BaseControl open fine by themselves.

Also, the application runs fine. I simply can't get to the form design view to modify the form objects.

Any helps is appreciate.

please open file basecontrol.cs, and replace Line 31

if (IsDesignMode)

with

if (DesignMode)

then compile the project - that should help.

Thanks VERY much for the quick response Serge.

that got rid of the error for basecontol.cs but I still get them for the other two lines.

OrderDraftControl.cs line 21 & 32.

Also, when I try to open MainForm I get errors on about 30 different lines / objects. I can send paste those errors if you want as well.

Are there these types of issues in every form? Is this a C# 2008 problem?

Thanks again,

actually, the change should prevent the PrepareControlEventHandlers method from execution in all classes.
Please try to rebuild the solution and then restart MSVS.

We do not work with VS2008, so I may only guess what the problem is.

Thanks. I just commented out the PrepareControlEventHandlers for now and it opens fine. I'll track down the exact issue later.

Thanks again for the quick response.
