Greetings.
I've downloaded the sample code of WROX's .Net Comact Framework book and,
when I try to try it in VS .Net with SDE April 2002beta , the following
error ocurs:

"An error occurred while loading the document. Fix the error, and then try
loading the document again. The error message follows:

The designer could not be shown for this file because none of the classes
within it can be desighned. The designer inspected the following classes in
the file:
frm*Measure --- The base class 'System.Windows.Forms.Form' could not
be loaded. Ensure the assembly has been referenced or built if it is part of
the project.
 *Measure --- The base class 'System.Object' cannot be designed."

I don't know why this occurs, and when I open a new project, the designer is
there!
Can anyone help me?

Bye :)

I would argue that the error is in the Sample project you've downloaded not
the CF Designer.  Chances are that they built the example under an earlier
build of CF and have not updated it for the new version.  You should
probably follow up with Wrox.

I'm not so sure... On numerous occasions when opening a SDE project or
solution the forms are shown in the Solution Explorer as classes (with a VB
icon rather that the gray forms icon). I found it very frustrating as when
loading like this I couldn't open the form using the designer. All I could
do was open it using the code editor.

I now get around this by adding a new form to the project and then removing
it. This seems to change all other form icons, and consqeuently allows me to
open the form using the forms designer.

Ok, that last post was before I had a look at the Wrox samples. So while
what I described there still happens, I think I know why you're getting
those errors. Jim is right, the problem is in Wrox's source.

First, the apps were created with references to other folders, i.e.
"..\SlnName\AppName". Seems that when packinging for download the forlder
names were changes to things like "Chapter02", "Chapter03" etc. So you have
to open the source in a text editor and fix that.

Next, some of the projects use the DataTimePicker control (eg is the
Adjuster project in chapter 3). This control will only ship with the SDE RC
so you have to modify the source to work without it, or create your own
DataTimePicker ;-)

Have fun!
