Hi Folks,
 
What I am trying to do
 
I am porting an old VS 2008 application from Psion TekLogic to Zebra symbol (handheld mc9200). The app is a winforms .Net application written in C#.
 
I have hit an issue where despite attaching a notifier to a form it is not being called, the notifier is being attached in a templatescanner class that is inherited by further classes. This code replaces existing code so I know the call mechanism etc is valid.
 
The code is as follows
 
In the attach notifier code (template class)
 
// Declarations
 
 
Barcode2.OnScanHandler myScanNotifyHandler = null;
 
 
 
// Inside the constructor
 
                    this.myScanNotifyHandler = new Barcode2.OnScanHandler(OnScan);
 
                    m_scanner.OnScan += new Barcode2.OnScanHandler(this.myScanNotifyHandler);
 
// further on in the template class
 
protected virtual void OnScan(ScanDataCollection sd) { }
 
In the child class(es)
 
 
protected override void OnScan(ScanDataCollection sd) {
// blah blah
}
 
Whats happening is that the text box that is given focus on the form receives the barcode I am trying to scan but the OnScan is not called (where I want to to do some pre-processing)
 
What I have tried
 
I have used the sample apps CS_Barcode2Sample1 and even CS_BarcodeSample1.VS2008 and basically copied everything they are doing to the letter but I am still getting the issue. A search of this forum and good old google shows nothing useful. I am completely stuck as to what the issue is,
 
Can anyone help?
 
Thanks in advance for any and all help
