View 1 RepliesI created a stored procedure in the Northwind Database using VS Server Explorer. So now when I try to use the Stored Procedure I get the error Error1 'GetCustomersInfo' is not a member of 'WindowsApplication1.NorthwindDataSet'. GetCustomersInfo is the name of the stored Procedure. This code works when I get the info from a table called Customers:
Dim ABindingSource As New BindingSource
With ABindingSource
.DataSource = ANorthwindDataSet
.DataMember = "Customers"
[code]....
Then I get the error. SO I guess I need to get the Stored Procedure into the DataSet somehow but I don't know how to do that.
I am creating a medium/largish program in VB Express 2008. To keep it more simple i have created each section of the program in individual projects/solutions and then when they all work well, copy the code from each project into one Big project. Everything was fine, but when i put the global variables all together in 1 module, i get the following error:'The type initializer for 'WindowsApplication1.Module1' threw an exception.' This appears everytime a line of code is ran that reads/writes to a var in the module.

I am just trying to call a little error check function, and if the return value, isOK, is false, let the user change stuff and then call the function again.

View 1 RepliesI have a Windows form Application that I am creating, could also be a Windows Service that I need to run.There are basically 2 Classes that were converted from java to vb.net and 1 xml file to this. for testing purposes I would like to use the Button.click event to manually run the code.However i get an error when trying to call the sub/function the normal way.I even tried to put this classes information in the Public Class Form1 but it keeps on giving me errors.This is the Sub:

so how do I call it from a Button.click event?
normally i would just do a "call main()" and it works however this time it is not because of the (byVal args() as string)

View 1 RepliesMy program has two forms. Let's call one Form1 and the other Settings. It's possible that Settings may be opened before Form1. Settings may also change some settings that need to be updated immediately on Form1. The thing is, if Form1 hasn't been opened yet, certain elements haven't been fully initialized (even tho Form1's properties can be modified since I do create an instance of the form on program load). Since these elements haven't been initialized, if Settings tries to modify them, it crashes the program.
Are there any ideas how, maybe to keep Settings from modifying stuff on a form that hasn't been loaded yet for the first time.
I'm trying to undersatnd the syntax of calling a funciton and it seem confusing when I'm using a web service in ASP.net. Maybe this question should be in an ASP forum, but it is a VB question. This simple web service allows you to type in your name and it response with an alert box with you name.
My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for
