How to create a Basic4ppc library

[taximania]

Your code gives me this error message when I open the project.

Error loading code-completion information for Microsoft.WindowsCE.Forms.dll from ?:
Could not find assembly file.

Any ideas ?

I'm not sure. I'm away now and can't check it. Your probably missing .NETCF developers package.
Anyway remove it from references. No needed for this project.

[taximania]

Thanks for the reply.

Opened a new project, cut and pasted your code.
I got it to build after adding a reference to system.windows.forms and adding the line 'Using System.Windows.Forms'

Works on the desktop It's just not on the form as CableGuy stated

Device now errors with, (get ready)

An error occured.
File or assembly name
'System.Windows.Forms,
Version=2.0.0.0,
Culyure=neutral,
PublicKeyToken=B77A5C5
61934E089', or one of its
dependencies, was not
found.

If I try to reload the dll I get on the device,

InvalidProgramException on the device

Have I made a reference to windows system.windows.forms and not the .NET system.windows.forms ??

Just deleted the reference and added the .net reference to the file.
No change. Still the same errors.


Don't rush to reply. I'm in no hurry.

Many thanks all the same

Taximania, I've come to notice that even when we change the c# code and Build the solution, sometimes,(idon't know why), the dll doesn't get built...and the first created dll is still there..

I alway check the date and time of the file present in the bin folder to make sure it's up to date...

Hi. I am having trouble using my first very simple DLL with Basic4ppc on the device, though I haven't yet tested it on the desktop yet.
When I write and build the following code:

public class test
public function ShowMe() as string
return "This is a test to see if this really works!"
end function
end class

The project builds correctly when targetting .net CF 2.0 but Basic4ppc on the device is giving me an unclear error.
Basic4ppc Error Test.dll
It doesn't say what the error is. My device runs the .net CF 1.0 which I cannot find its SDK, so I assumed compatibility with the .net CF 2.0 and .net CF 1.0 when writing this simple code.
I am at least excited I got thus far, but can anyone tell me what's wrong? I'll try the same DLL using the desktop IDE and see if I can at least compile an app linked with this DLL.
Thanks all!
Well, the desktop references to it fine, but Basic4ppc sees no classes or objects to add.

Its the other way around...
If a dll target .NET CF 1.0, device running .NET CF 2.0 will run it, but if a dll targets the .NET CF 2.o the device MUST sbe running .NET CF 2.0 and the apropriate config file must be placed in the Basic4PPC folder...

In the BASIC4PPC web page there's a tutorial on how to "see" your cf version, and how to install the cf 2.0

Some links about various .NET SDKs. Please Read carefully these pages and download the apropriate files.

@taximania
Looks like you compiled your dll as a compact framework 2.0 dll and you didn't install .netcf 2.0 in your device. Don't forget to add YourApp.exe.config file.

@Louis
Cableguy is right. You can't run 2.0 dll in a device with .netcf 1.0. Look at links above for .netcf 1.0 sdk (I'm still not sure if it exists out of Visual Studio)

Well, the desktop references to it fine, but Basic4ppc sees no classes or objects to add.

Your class must have a constructor (a New method for vb.net) and is good to have a Dispose method. See vb.net examples posted in this thread earlier.

Pure .Net development (especially with #develop) is by far more complicated than Basic4ppc. But don't give up, your libraries are coming!

[Cableguy]

Thanks to everyone's input, especially of DZT, I'm in the fast lane on my dll creation sprea....

I'm thinking about addind some sort of string manipulation controled by a timer, from one of my inputs...and maybe have it turn on/off by a boolean...
Where in the code do I place it?

[dzt]

Timer is one more control, like a button but without GUI. Add it and handle it's Tick event. Enable it or disable it, using a property like Left.

HELP!!!

I have (hopefully) one more question...

In my custom form controls I have a picturebox, wich will receive its filename from a public property called "Logo"...
how to set it?

Picturebox.image=............Logo

please fill up the blanks...!
