Unclear Syntax In Procedure?
Dec 7, 2010
Currently going through Murachs beginning VB.NET adn come across some code that I am do not understand. I have attached a document of the application. If the user clicks on the future Value radio button the ReadOnly property of the Future Value text box is set to true and a CaluclateFutureValue procedure is called. If the user clicks on the Monthly Investment radio button it sets the ReadOnly property of the Monthly Investment text box to true so a user can enter a value. A CaluclateMonthlyInvestment procedure is called. The code of the procedures is as follows:
Private Sub CalculateFutureValue()
lblFutureValue.Text = _
FormatCurrency(FV(txtInterestRate.Text / 12 / 100, _
[code]......

I have a dataset with a bunch of tables in it. I also have a database with the same tables, but not necessarily the same number of rows. Any table in the dataset will have the same rows as there are in the equivalent table in the database, but there may be a few extra in the dataset. What I'm looking for is a fast way to determine whether there are extra rows, and if so, they need to be inserted into the DB.

I am not a VB programmer, but I assumed for the most part that the syntax is C like, I received the program above from a non-technical recruiter with the following input f1("enritcde3 dtyeds4t8", 2). From my understanding the following output would be ("enritcde3 dtyeds4t8",2,2,2,""). Am I missing something?

I am making a visual basic game. And in the game I have a few instances where I want to call open a window (let's save to save the user's preferences) from a form, then I want to go from that form to another one.
Example:
The user has completed the new game page. I have the users choices in a host of string, integer, and boolean variables. Now I want to use a generic saving screen I made with a progress bar. When I open up the saving box, I want to close or hide the new game setup menu (whichever I need to do). Then when it is done saving I want the Saving bar to return and cause the new game form to open the actual game form and close itself.
So I guess my question is this: What is a reliable(or correct) way to poll for a return in form to signal it to go ahead with execution?
Second:
This is similar to the first question. Instead of keeping the first form open when I use the saving form; is there a way I can save the name of a page I want the saving bar to go to once it's done?
I want the user to enter their prefered username before they start a new game for the first time. So I poll the saved username setting I have and if it equals "username" I want the Username entry form I made to pop up, but once it's done I want it to immediately call the new game screen. I also want to use this username entry form on the options screen so that the user can change their accepted name at anytime; but I want this screen to return back to the options screen.
What is the accept way to do this? Is it done through stacks? (form information -> stack : load new page : Do stuff: load stack value -> goto)
Finally:
Do I have to keep a window open (not close it) to access the variables that I have defined in it, and have stored values too? Does this apply to hiding too?

I have a VB2002 program that works. When I run it in VB2008, it updates, and runs and debugs until I shut down. When I try to start it up again from the updated SLN, or try to run the .exe in the BIN folder, I get the message "This application has failed to start because the application configuration is incorrect.
I checked the error logs and it says there is a syntax error in the first line of the vhost.manifest file in the BIN folder. The first line is the xml declaration and it includes the parameter standalone = "yes".
When I put the error message into Google I only get references to Visual C++ compiled programs running on machines without the C++ redistributable dll. That doesn't seem to apply here at all, since I have the VB 2008 express edition installed on this

The instructions are as follows:
1. Write a Visual Basic Console Application.Inside the main procedure call a function procedure to input and return a value for a double variable called x, the width of a right triangle.Inside the main procedure call the same function procedure a second time to get a value for a double variable called y, the height of a right triangle.
2. From the main procedure call a function procedure which calculates and returns a value for the hypotenuse equal to the square root of (x squared + y squared).You will have to pass the values of x and y to this function procedure.The procedure should calculate and return a double type value.The value that is returned by this function procedure should be equal to the square root of (x squared + y squared).
3. Also from the main procedure call a sub procedure to display the values of x, y, and the hypotenuse.

In a tic tac toe game I am making there are two blocks of code that are identical except that they access different arrays:[code]Arrays plyrTaken and plyrPairs are used in the first block and cmptrTaken and cmptrPairs are used in the second. Is it possible to wrap these blocks into one Sub Procedure passing the different arrays when the procedure is called?

I have a stored procedure to update a table, but needs a couple of values from another table.
the first two selects get the value from the table and then are used in the update statement.
The select statments:
Select @iStatusDropDownValueID = iDropDownValueID
From DropDownValue
Inner Join DropDownValueType On DropDownValue.iDropDownValueTypeID =
[Code].....
First, the values that are retrieved by the first two select statements are always the same. So they could be passed in by the code itself. I don't know that this will speed things up at all, just make the entire stored procedure better and easier to read.
Second, if the "Value Name" should change this store procedure will break (which is possible, but not often).
I am looking for any insight into the Best Practices for this situation.

I've never understood this and just used examples, but I would like to understand what is going on here. What exactly is the stuff inside the <> brackets? How are these related to Service1? I understand the ServiceBehavior is related to the hosting, but what about Foobar?
