Pass An Array Of String When A System.Array Is Expected?
Feb 24, 2009I am writing an OPC Client in VB.NET (2008) and I am using an OPC wrapper from Graybox. I am having some problems with the data types. I have an Array of String that contains all of the OPC Items that I wish to read from the OPC Server. When I attempt to use the Array of String, Option Strict causes the following compile error message:Error 5 Option Strict On disallows narrowing from type 'System.Array' to type '1-dimensional array of String' in copying the value of 'ByRef' parameter 'ItemIDs' back to the matching argument. How do I pass the Item ID's (all strings) in an array?
View 1 RepliesConverting System.array To Double() Array?
Jun 12, 2012just hoping that someone may be able to assist me to convert system.array to double() array.
Declarations are as follows:
Private f_Data As System.Array
Private f_Measures() As Double
Private f_NumberOfObservations As Integer
I then 'fill' f_Data from a range in an Excel worksheet as follows:
f_Data = wsXLSData.Range(wsXLSData.Cells(1,1), wsXLSData.Cells(8, 1)).Value
This seems to work OK. Upon checking f_Data is indeed filled with 8 double type numbers.
I then try to convert this system.array to a double array as follows:
For i As Integer = 0 To f_NumberOfObservations - 1
f_Measures(i) = f_Data(i + 1, 1).value
Next
I then get an error pointing to the line ' f_Measures(i) = f_Data(i + 1, 1).value' of type MissingMemberException was unhandled by user code'

Also once the user hits reserve seat the first seat number should turn from green to red in the section they selected. If the user was then to hit reserve seat again the next seat (seat 2) would turn from green to red and so on. I know I have to use a control array. This is how far I have gotten.
