| Subject: | Exception occurs in VB for SetSPELVar with empty TextBox |
Symptoms
If a VB string variable is set to the value of an empty
TextBox and then passed in the SetSPELVar method, an exception occurs and the
system must be re-booted.
Dim tmpStr As String
tmpStr = Text1 ' Text1 is empty
SPELCom1.SetSPELVar "g_Parameter$", tmpStr
Cause
The cause is not yet known.
Remedies
There are two methods for work around:
Method 1
Pass the text box directly:
SPELCom1.SetSPELVar "g_Parameter$", Text1
Method 2
If the string is empty, then pass an empty string,
otherwise pass the string variable.
Dim tmpStr As String
tmpStr = Text1
If tmpStr = "" Then
SPELCom1.SetSPELVar "g_Parameter$", ""
Else
SPELCom1.SetSPELVar "g_Parameter$", tmpStr
End If
Status
This problem is being investigated.
