I have gotten this far with a lot of help. One last problem to solve.

here is the code that I am using:

Let ( setup = WAReset and

WASetInputValue( "TextBCID" ; "00" ) and

WASetInputValue( "TextSpecial" ; "700" ) and

WASetInputValue( "TextCustID" ; "666666" ) and

WASetInputValue( "TextSeq" ; "123000001" ) and

WASetInputValue( "TextRouting" ; "974027547" ) and

WASetInputValue( "ButtonEncode"; "Encode" ) and

WASetInputValue("__VIEWSTATE"; "dDwtMTEyNDk2MDIxMTt0PDtsPGk8MT47PjtsPHQ8O2w8aTwyOT47aTwzMz47PjtsPHQ8cDxwPGw8VGV4dDs+O2w8U3BlY2lhbCBTZXJ2aWNlcyBtYXkgbm90IGJlIGJsYW5rIG9yIGluY29tcGxldGU7Pj47Pjs7Pjt0PHA8cDxsPFRleHQ7PjtsPFxlOz4+Oz47Oz47Pj47Pj47Psv4UmUq6hIjoYeMNE2CNgnSjrb8") and

WASetInputValue("customeridlength"; "6")

;

WAGetURL( "http://ribbs.usps.gov/onecodesolution/Barcode_Encoder.Aspx" )

)

The page is now returning the following error:

See the following post for the error message.

Thanks mfero for getting the correct error message posted for me.

If some one could give me a pointer as to how to solve this it would be greatly appreciated.

Thanks

Have changed the sequence of entering the lines of code with no change in behavior.

You posted a bunch of unintelligible HTML into your post. The error message is as follows:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

[NullReferenceException: Object reference not set to an instance of an object.]

USPS_4SCBCode_Client.Barcode_Encoder.ButtonEncode_Click(Object sender, EventArgs e) +933

System.Web.UI.WebControls.Button.OnClick(EventArgs e) +108

System.Web.UI.WebControls.Button.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) +58

System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +18

System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +33

System.Web.UI.Page.ProcessRequestMain() +1292

Does that help?

Sorry about the HTML. You manage to get posted what I was trying to do.

That is the message that I get when I run this code from the plug-in. How do I correct so that it does not return an error message but returns the correct data. Which would be the same as if you filled out the form in a browser and and click the encode button.

Thanks
