Errorcode doesn’t belong to OpcException anymore

Hello.

In your catch handler, do something like (I have not tested it in the compiler but I believe it is basically correct):

var comException = ce.InnerException as COMException;
if (!(comException is null))
{
    uint WriteError = (uint)comException.ErrorCode - 0xC0041000;//0xC0041000 is coming from the server.
    switch (WriteError)
    {
...
Best regards

Hi Z,

I have upgraded QuickOPC Classic from version 5.53.315.1 to version 5.62.456.1

When I compile I have an error saying that Errorcode doesn’t belong to OpcException anymore. Any suggestion or alternative for this?

My old code:
try
{
     easyDa.WriteItemValue(server, dai, value);
}
catch (OpcLabs.EasyOpc.OperationModel.OpcException ce)
{
     uint WriteError = (uint)ce.ErrorCode - 0xC0041000;//0xC0041000 is coming from the server.
 
     switch (WriteError)
     {

Best regards
BertilG
