Hello,
i build a project in vb.net with the wrapper.
IR transmission works well but i get an unmanaged error when the IR learning completes (100%).
Here is a zip of my project:
http://snort.free.fr/usbuirt/testusbuirt1.zip

Question: as i have the wrapper.net source code, is there a way to include it in my project and debug it ?

thanks in advance

I haven't had a chance to look at your code yet...

Yes, you should be able to include the Wrapper as part of your project rather than merely adding the Class Library reference.

Can you give some details? What's the error you see? Does it happen evey time?

[Olivier]

it happens at 95 times on 100.....

Learning progression works well but when it reaches 100%, i get this error: Instruction at "0x00191073" use memory adress "0xffffffff". Memory can not be read.

Note: i cant manage this error through the debugger
Note2: test app in C# provided with the .net wrapper works well.....

please.......

[Olivier]

don't ask me why but it works now.....
thanks all for ur help

Can anyone help me with some VB .net example code?

I need to write a program to learn codes, store them and play them back on demand (a custom remote control).

Thanks in advance!

One possibility (although I'm not much help in tracing this out for you), is that the Grabage collector has freed up the variables (pointers to those variables) you passed to the Learn function. There is some .NET docs talking about how to tell the Garbage collector not to free up a variable it 'thinks' is no longer in use.

However, I don't believe this should be a problem since you should be doing a non-Async learn...

i solved this bug using a debug version of the .net wrapper ....
