Why Won't This Function Work For My Program. (Visual Basic)

I'm doing a baseball program for a class project. And I almost have it complete, but it's giving me a syntax error. I can't figure out what i'm doing wrong. I'm using two functions to return a value for different type of baseball tickets to the button that calculates them. Here are the instructions 1.)User selects whether to purchase season tickets or single-game tickets 2.) User enters the number of tickets needed and the type of seats based on whether they selected season single-game tickets.3.) User clicks the Compute Ticket Cost Button to display final cost4.) User clicks the Clear Form button to clear the responseI just can't figure out what I did wrong. I know it's something stupid that i'm doing.the errors are happening inside the btnCompute sub routine. with syntax erros on SingleGameCost() and SeasonalCost() line 114 and 118
Public Class Form1

What does this error mean in VB6? Function or interface marked as restricted, or the function uses an Automation type not supported in Visual Basic.
I keep getting it when i call a particular method of a dll that comes with windows xp and beyond (in system32 called upnp.dll)

I am trying to make a console program in Visual Basic on Visual Studio 2008. I want to ask the user of the program if he wants the premium version or the standard version. If he chooses the premium version, then I want it to say premium in his "receipt" later on and if he chooses standard, then standard in the receipt.

I have visual studio 2008 installed and was using C#. I am now trying to find Visual Basic. I can't find it. Is there a way to download it or should it be somewhere in my visual studio program? I don't want to use vbexpress, just regular VB 2008.

Is there a simple sleep function in Visual Basic that doens't involve thread.
Something similiar like there exists in: C: sleep(1);
We also tried this code:Declare Sub Sleep Lib "kernel32" (ByVal milliseconds As Long)' pause for 5 seconds
Sleep 5000 but it didn't work. It gave me this error: PInvokeStackImbalance was detected

I have a Visual Basic 2008 Express Edition application that operates as a front end for iSeries V6r1. The application was developed on a windows 7 machine. Users load the application from a shared folder on a server. Currently, there are 2 Vista, 3 windows 7 and 4 XP users. All had no problem in loading application, all users except 3 of 4 XP users can run the application with no problems. However, 3 of the XP users receive the following error message when they perform any action that tries to connect to the iSeries:
System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
All 4 XP users are on same service pack

I am trying to transfer a very complicated Matlab function into visual basic. It takes a matrix input and gives 4 outputs.
From my own research I found something called Matlab CODER, which can transfer matlab code into C/C++ code, however, this function is too complex for that. So I guess now my question is, it is possible to call my matlab function somehow within VB and store the outputs for use within my VB program?
The matlab function looks something like this:
function [f,x,s,c,l] = mytest(Y,varargin)
%Code here...
end % function

I'm working on a small freeware application in Visual Studio 2008 Standard that will match geographic data to a geographic position. For this I need some mathemathical functions and one of them is how to detect if a point is inside a polygon. There's a great solution for this from the Microsoft team at: [URL]
but it is in a different programming language that I do not know anything about. How can I use these functions in my program? I'm afraid that if I try to rewrite them in Visual Basic I'll make mistakes that I can't detect. To be complete, I'm not using screen graphics so I really need a mathemathical solution.

I have a procedure at the end of my console application that ask the user to either hit enter to end the program, or type s to perform another search. The issue I'm having is no matter what the user types in the program end. What I would like to happen is if the user types s, then the program starts over and lets the user perform another search. The program is procedural and I need to find a way to start back off at the top of the program which ask the user to type a name to search.

I am working to make a function that will update the back color of a text box based on multiple variables values. I can write the code to do the calculation, but I am not sure how to make the function realize which text box to update (as I will have about 30 different boxes). Below is the code that I have for each box so far, but I will have quite a few more, and would rather use a function to reduce the amount of code, and also make it cleaner as well.
If sngPreviousPrimaryPropertyTotal >= sngPrimaryPropertyTotalCost Then
txtPreviousPrimaryPropertyTotal.BackColor = ColorProgramLightGreen
Else
txtPreviousPrimaryPropertyTotal.BackColor = ColorProgramLightRed
End If
[Code] .....
Or is there a way that I can tell the function that it's updating the text box that call the function in the first place? Say if txtBox1 has updated text and calls the function, then the function 'knows' to update txtBox1, but will update txtBox2 when it's called by txtBox2.

In my VB.net code i have:
cmd.CommandText = "SELECT * FROM [strfg].[dbo].[Myfunc] (@MyParam)"
Dim myparam As New SqlParameter("@MyParam", a)
cmd.Parameters.Add(myparam)
The function (runnig on SQL server) returns a table with four columns, one row.How do I call this function from Visual Basic? cmd.ExecuteScalar() is obviously not correct. In c++ I use a recordset. What is the equivalent in vb? Does anyone have a short example?

Anyone know of a way to do addon's with a visual basic program? I want to create a program that has some basic functions, but to stay away from bloatware and unused functions. How would you create a main program when it is installed and then be able to add and remove features to it?

I have a program written in VB.NET which stops a service that uses file x, modifies x, and restarts the service.
I have modified my code for testing so that it just reads in the file as a string and immediately writes it back out.
Shell("net stop " & SERVICE_NAME, , True)
Dim myReader As System.IO.StreamReader
myReader = My.Computer.FileSystem.OpenTextFileReader(x)
fileString = myReader.ReadToEnd()
[Code]....
The stopping of the service is no problem, and modifying the file is no problem, but when the service starts it stops immediately because, as best I can guess, the file is in use. Even when I try to start the service manually, it stops immediately. However, I found that I can open file x, click save without modifying anything, close the file, and start the service and everything works correctly.
If I comment out the writing part, everything works fine.
Also, the file I'm modifying has a .conf file extension. I don't know if this is relevant.
