C# sample code.

[laktej]

I can see we have C# sample code for ISOTP and PCAN basic. Do you or anyone have a sample code for client side C# UDS sample?

[K.Wagner]

Hello,

Sorry, we don't have any sample in C# for UDS at the moment. This is still in our todo list.

Thank you for letting me know.

i was trying to initialize the device like this but i am getting an exception like below

Code: Select all

        private void buttonInit_Click(object sender, EventArgs e)
        {
            TPUDSCANHandle p_handle;
            TPUDSStatus sts;
            p_handle = UDSApi.PUDS_USBBUS1;
            sts = UDSApi.Initialize(p_handle, TPUDSBaudrate.PUDS_BAUD_1M, 0, 0, 0);

            if(sts == TPUDSStatus.PUDS_ERROR_OK)
            {
                TextSts.Text = "initilize";
            }
        }

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

please let me know what wrong is happening?

Hello,

this error means, that your application is loading the wrong version of the PCAN-UDS.dll. Either your application is configured to work as 64 bit, and the dll you are using is the 32 bit version, or your application is a 32 bit one and the loaded dll the 64 bit version.

Check the build options of your application and be sure that it matches the platform of the dlls you are copying in your output folder. All three have to be the same platform, PCAN-Basic.dll, PCAN-ISO-TP.dll, and PCAN-USB.dll. FYI, the details tab of the file properties of each dll shows also the platform for which they were compiled (right mouse click on the file, then select properties, then select the tab Details)

Hi,

I keep on trying to run the c# sample code for PCAN ISO TP, but I always get this error:

Any clue how to solve this? The PCANBasic worked fine for me, but trying to use the CanTpApi is quite challenging even after I pasted both dlls on my System32 and SysWOW64 folder.

Hello,

this is the same problem (mixed up Dlls in Windows\System32 vs Windows\SysWOW64). Follow the instructions in the link mentioned by laktej, to copy all API dlls:

Hi,
Thanks for clarifying the copying procedure of the dlls. I can now initialize smoothly.

hello,

you're welcome.
