Problem: Custom control not drawing on Form from Designer.

B

Brian McVay

Hi all,

I have created a custom textbox control using VS2003 C# to use in a VB.NET
CF project. In an application test for the desktop the control works just
fine (although some polishing is still needed) , however, for an application
targeted for the Smart Device Application the control does not draw onto the
form at design time.

I have followed the rules inside of the .NET help for compiling the design
time control using the command line compiler and have successfully added it
to the VB.NET toolbar for Smart Device Application in the Designer... but
the designer simply does nothing when the control is selected to add to a
form.

Can anyone provide any feedback on what I am not doing or what I am doing
wrong?

I have provided the control code below for what I currently have.

Thanks in advance.

Too true!

I read the entire article and placed the missing attribute before the
namespace, recompiled both the runtime and the designtime components as it
said. Went back into my application and removed the references and re-added
the new references. However, the control still will not add to the form at
design time.
Any idea what i might still be missing?

This might sound odd, but are you sure that you're working in a device
project? I assume that the code that you initially posted compiles fine for
you... but it didn't even compile for me. It looks like you're trying to use
the static Equals method on the Comparer class that takes two arguments. The
only Equals method overload that is supported is the one that takes a single
argument. Could that be your problem?

myReturnValue = Comparer.Equals(myChar, SpecialCharacters[intFoundValue]);

Does not sound odd at all.

In fact, in research, it appears to have the elements of a
WindowsApplicationControl rather than a SmartDeviceProject. SO....

I started over with a new project, selecting Smart Device Application using
a Class Project for Pocket PC devices. I copied my code from the other
project into the new class for the device project and got the same error you
described. I replaced it with the following for a quick test:

//myReturnValue = Comparer.Equals(myChar, SpecialCharacters[intFoundValue]);
int myTest = myChar.CompareTo(SpecialCharacters[intFoundValue]);
if (myTest == 0) myReturnValue = true;

This compiled fine for a Smart Device Class project.

I recompiled the runtime version and then reset the assembly information for
the design time and ran the command line compiler against the new assembly
and moved the new runtime and design time files to the appropriate
directories.

I created a new test application for Smart Devices with only one form and no
code. Made sure that all references paths were added to the new project for
the new control. Added the new control to the toolbox, and it still failed
to draw on the form.

Ideas?

Thanks for all the help you have already provided!

I just compiled everything and dropped the control onto the Form as
expected. Here's what I did.

With the original source that you posted, and those changes that you made in
the last post, I made a few more code changes.
(1) I moved the reference to the RuntimeAssemblyAttribute outside the
namespace.
(2) I set the AssemblyVersion to "1.0.0.0" ([assembly:
AssemblyVersion("1.0.0.0")]).
(3) I set the Version in the RuntimeAssemblyAttribute to "1.0.0.0" to line
up with the AssemblyVersion attribute.

Next I built the run-time version. Simple build through the IDE.

Then I built the design-time version using the following script.

csc /noconfig /define:NETCFDESIGNTIME /target:library
/out:ABCTextBoxControl.Design.dll AssemblyInfo.cs ABCTextBox.cs
/r:"E:\Microsoft Visual Studio .NET 2003 Enterprise
Architect\CompactFrameworkSDK\v1.0.5000\Windows
CE\Designer\System.CF.Design.dll" /r:"E:\Microsoft Visual Studio .NET 2003
Enterprise Architect\CompactFrameworkSDK\v1.0.5000\Windows
CE\Designer\System.CF.Drawing.dll" /r:"E:\Microsoft Visual Studio .NET 2003
Enterprise Architect\CompactFrameworkSDK\v1.0.5000\Windows
CE\Designer\System.CF.Windows.Forms.dll" /r:System.dll /r:System.Drawing.dll
/r:System.Windows.Forms.dll /r:System.Data.dll /nowarn:1595

Of course, you'll need to replace the paths to the appropriate paths on your
dev machine.

I then copied the run-time assembly to the
"...\CompactFrameworkSDK\v1.0.5000\Windows CE" directory and the design-time
assembly to the "...\CompactFrameworkSDK\v1.0.5000\Windows CE\Designer"
directory.

Then I created a PPC application, and then added the control to the ToolBox
by right-clicking on the ToolBox, choosing "Add/Remove Items..." and then
locating the design-time version of the control (the one in the
"...\Designer" directory).

Next, I dragged the control out of the ToolBox and onto the Form and it
appeared as expected.

Does not sound odd at all.

In fact, in research, it appears to have the elements of a
WindowsApplicationControl rather than a SmartDeviceProject. SO....

I started over with a new project, selecting Smart Device Application using
a Class Project for Pocket PC devices. I copied my code from the other
project into the new class for the device project and got the same error you
described. I replaced it with the following for a quick test:

//myReturnValue = Comparer.Equals(myChar, SpecialCharacters[intFoundValue]);
int myTest = myChar.CompareTo(SpecialCharacters[intFoundValue]);
if (myTest == 0) myReturnValue = true;

This compiled fine for a Smart Device Class project.

I recompiled the runtime version and then reset the assembly information for
the design time and ran the command line compiler against the new assembly
and moved the new runtime and design time files to the appropriate
directories.

I created a new test application for Smart Devices with only one form and no
code. Made sure that all references paths were added to the new project for
the new control. Added the new control to the toolbox, and it still failed
to draw on the form.

Ideas?

Thanks for all the help you have already provided!

I just followed your instructions to the letter, and I still cannot get it
to show on the form.

Tim, I want to thank you for taking all this time and effort to assist me
with this.

Just to make sure that I *could* do this, I followed the instructions from
the Graph example that you linked earlier, and it works like a champ in the
very project that I am trying to get this textbox to work in.

I tried another small control and it works perfectly as well. There is
just something with this control and/or my environment that is preventing it
from working ... but what... i have no idea.

Again, thanks for all your help.

Brian

Are you able to zip and post your whole control project as is? If you do
that I'll take a look through the project to see what's going on.

Thanks Tim.

I decided to try it once more time this morning. Using the same projects as
before, I wiped all references, physically deleted all of the compiled
files, rechecked all the code and batch files (no changes), recompiled and
moved the files out. Set up the toolbar again and set the new references.

Lo and behold it worked perfectly. I guess something was hung up on the
references or they were not being replaced correctly with the new reference
to the new compiles yesterday even though I was removing them then too.
Weird.

Thanks for your willingness and great assistance.

Brian.
