View 1 RepliesI'm using ASMX web services in VB.Net in VS 2005. I am calling a function method on the web service that returns a true or false value. This works fine if I call the the web method synchronously, but if I want to call the method asynchronously, the function returns to a sub and there is no return value; therefore, I can't tell whether the result of call is true or false. Is there a way to make an asynchronous call and still get the true or false result (perhaps using the userState Object)?
For Example:
Dim MyResult as Boolean = MyService.GetResult(10)
Dim MyResult as Boolean = MyServer.GetResultAsync(10)
This doesn't work the compiler complains: "Expression Does Not Produce a Value"

Base class has one field to hold numeric balance value. With 2 methods that accept arguments for adding and subtracting the new input calculating new balance. Sub class has four fields dates, transaction, memo and amount.I have a deposit form, and withdraw form. Each time one transaction is entered it creates an object with sub class fields, then adds to the account collection. My problem is not understanding how to call the deposit/withdraw method and pass the current transaction amount back to the base class to alculate the new balance. Does anyone have any links to information/tutorials on how to perform something like this? As you can see with my code I have tried various different approaches without any success.

I have a class i've called "buttons", which passes in 1 variable, the button text, and then returns a new button with that text. however, i do not know how to get the class, when called to return a button.
similar to how 'toString' works, except it would return a button object instead of a string. (im not sure how toString works in vb.net. in java it is automatically called when you call the new class, so newclass and newclass.toString(); return the same) [code]...
I wrote the following two functions in a class to take a gpib reading and also take a measurement from an LCR meter.
HTML
Public Function gpibRead(ByVal Channel As Integer, ByVal buffer As Integer) As String
Dim readingBufferA1 As String
Select Case Channel
Case 1
readingBufferA1 = gpibLCRA1.ReadString(buffer)
Return readingBuff
[Code] .....
When on the main form I call the funtion takeMeasurement(1) how can I get the LCR readings back. If I try and use readingBufferA1 on the mainform it doesn't recognize that as a variable. I know that it is taking the reading and storing the correct numbers because I am monitoring on NI Spy.
