Hiya I got a problem with getting things to run,
Ive started of just to get sample code to run but it stopped me already there hehe
Im using 8056 since before in several applications and no problem with that.

I have Visual Studio 2008 (not express, bought the prof edition)
Here is where I get stuck:
k8090.connect()
shows the error “Unable to find an entry point named ‘OpenDevice’ in DLL ‘K8090D.dll’.”
and I got the component addressed to the driver…
and the comport are the same as in device manager, demo runs fine.

If no answer on this able to get source code to demo??

Best regards

This means that the application found the DLL, but it cannot find the exported function called ‘OpenDevice’ inside the DLL.

Do you have another file called ‘K8090D.dll’ on your system that is not a DLL provided with the installation package?

there wasnt any k8090.dll in the package, I renamed Velleman.Kits.dll to k8090.dll as a try but no difference…

The installer copies K8090D.dll to your system32 folder (for XP this is C:\Windows\System32). Don’t rename the Velleman.Kits.dll because this is a .NET assembly, not a regular dll.

If you don’t find the file on your system you can download it here
K8090D.zip

I had that dll before downloaded it separate because there wasn’t any in the setup, tryied it again and sample didnt work…
But now when I knew that I had the right dll I did som testing and found out why it didnt run.
It was because of .NET wanted to compile application for 64-bit system, after changing to x86 compiling
it worked fine.
Thnx for the help and have a nice weekend :slight_smile:
