Issue after updating Peak.PCANBasic.NET to version 4.10.0.964

[LudovicC]

Hello everyone,

I am using .NET framwework 4.8 to make a C# class library using the Peak Basic API.
I was until yesterday running the version 4.9.0.942 without issue.
Then I have noticed in the Nugget package that 4.10.0.964 was available with a new parameter PCAN_DEVICE_GUID, which sound very interesting, hence I have decided to update to the latest version. Quite a bad idea to try that right before Christmas vacation !
After the update, my code is not working anymore. I am not originally a C# programmer, so maybe I have missed something very basic.

I have two projects in my solution a "Class Library (.NET Framework)" which is my main code, and a "Console App (.NET Framework)" which is for testing my class library.
I have also downloaded from Peak website the latest PCAN-Basic with "Download Latest Version".

Therefore, for the update I have:

• Updated the Peak Nuget package to 4.10.0.964 for both projects
• Copied in each project's folder the file "\PCAN-Basic\Include\PCANBasic.cs".
• Copied the file "\PCAN-Basic\x64\PCANBasic.dll" into the folder "C:\Windows\SysWOW64"
• Copied the file "\PCAN-Basic\x86\PCANBasic.dll" into the folder "C:\Windows\System32"

And then, in my code, I just create a new Worker with the parameters PcanChannel.Usb01 and Bitrate.Pcan500.
And when I try to do "myWorker.Start()", I get following error:

System.BadImageFormatException: 'An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)'

Error: The type initializer for 'Peak.Can.Basic.Api' threw an exception.
StackTrace: at Peak.Can.Basic.Api.SetValue(PcanChannel channel, PcanParameter parameter, UInt32 buffer)

But everything was fine before I had performed the update.
Anyone would have an idea?

Hello,

First of all, you should always use the PEAK-Drivers Setup to install the PCAN-Basic files. Manually copying the files to the system folders can end in copying the files wrong, like in your case:

Copied the file "\PCAN-Basic\x64\PCANBasic.dll" into the folder "C:\Windows\SysWOW64"
Copied the file "\PCAN-Basic\x86\PCANBasic.dll" into the folder "C:\Windows\System32

The x86 version of the DLL belong to the folder C:\Windows\SysWOW64
The x64 version of the DLL belong to the folder C:\Windows\System32

Copied in each project's folder the file "\PCAN-Basic\Include\PCANBasic.cs".

Second, if you use the NuGet Pacakge you do not need the PCANBasic.cs file. You can read the How-and-Tos section of the documentation for more information.

Hello Keneth,

Thanks a lot for your fast answer!
Installing the drivers 4.6 solved it.
I will definitely keep this best practice in the future.

Now I can test this new TPCANParameter.PCAN_DEVICE_GUID. Which lead to other question, but I will make a new post to keep it clean.

I appreciate you pointing out the proper PCAN-Basic file installation process! In the future, I'll make sure to avoid manual copying and utilize the PEAK-Drivers Setup. Additionally, I will see that the NuGet Package choice removes the requirement for the PCANBasic.cs file. Thank you for the clarity!
