I'm going through the Jump Starts in order and have had no problems thus far. However, on substep 5 which reads as follows:

"Now that you've set the BindingSource property for all these controls, you need to set the BindingSourceMember individually for each text box.

Click directly on the form to deselect all text boxes, and then select the Order ID text box. Go to the Properties Window and select the BindingSourceMember property. Click the associated ellipses button to launch the Binding Source Member dialog:

This dialog dynamically reads your web.config file to determine which databases you are using in the application and changes the display of the dialog accordingly. If this dialog fails to display properly you may have a problem in the connection strings specified in your web.config file."

I encounter the failure to display the Binding Source Member dialog and get this error message:
---------------------
at OakLeaf.MM.Main.Builders.mmBindingSourceWebMemberEditForm.GetDatabases()
at OakLeaf.MM.Main.Builders.mmBindingSourceWebMemberEditForm.GetDatabaseSets()
at OakLeaf.MM.Main.Builders.mmBindingSourceWebMemberEditForm.GetDatabaseInfo()
at OakLeaf.MM.Main.Builders.mmBindingSourceWebMemberEditForm.Init(Object value)
at OakLeaf.MM.Main.Builders.mmBindingSourceWebMemberEditForm..ctor(Object value, Control currentControl, ITypeDescriptorContext context)
---------------------

(In that last line of error message...is the poriton with the two dots (..) valid? That just looked odd to me but I've not made any changes to the Builders)

I also have the following error message in my Task List:
---------------------
Code generation for property 'SecurityManager' failed. Error was: 'Object reference not set to an instance of an object.'
---------------------

Any ideas? I can manually input the BindingSourceMember values and the solution builds and runs just fine in the browser (though I still have the error in Task List).

Thanks

Never argue with an idiot. They drag you down to their level and beat you with experience.
