VS 2010 Converting String To Short?
Jan 5, 2011
Working on a Sudoku program and I want to read a puzzle in from a file. So, I read the file in as a string in the form --3-2--1- and so on, where - means nothing starts in that cell. How do you convert a string to a short? I found the cshort function but it doesn't seem to work. Is there a different way or am I making some other mistake?
SudokuPuzzle is a string where I read in the file. squareValue(i,j) is the number is the ith row, jth column position of a correct solution I used 1 to 9, 1 to 9 as the indices for my puzzle (and just ignore the 0, though I did Dim as (0 to 9, 0 to 9)), so that is why I have the i - 1 and j - 1 in there.
For i = 1 To 9
For j = 1 To 9
If SudokuPuzzle.Substring(9 * (i - 1) + j - 1) <> "-" Then
squareValue(i, j) = CShort(SudokuPuzzle.Substring(9 * (i - 1) + j - 1))
End If
Next

I'm trying to get the first checked item from a checked list box and turn it into a string. I tried using [code]But that threw an error at me: "Conversion from type 'FileInfo' to type 'String' is not valid." So then I thought of dumping it into an array. But then I couldn't convert the array to a string.Remember I only want one value. array(0)

In my project I need to use a 190 very long strings with different number of characters (4-60).I want to mark them in a short form with the numbers 001, 002, 003 ... 190. Is there an easy way to display the full name of the string when I choose a short name ? Of course, I do not want to write 190 times "if - end if" and also I would like to avoid a complicated database. Onenew Visual Studio 2010

I am using the .NET Framework 2.0, and I am trying to code a client bot for a game called Minecraft, Originally written in Java, there have been quite a few people who have made custom multi-player servers for this game, Primarily in C#, or in a language that i've never heard of, such as Pascal.I'm looking right now at sending this:
Packet ID: 0x00 (0) As Byte
Protocol Version: 0x07(7) As byte
Username: "umby25" As String
[code].....
"Byte cannot be converted to 1-Dimensional array of byte"
I don't understand why this whole thing would work in all of the other programming languages, but not Visual basic.I have tried converting the string using the same method that one of the open source C# servers used, and it failed, telling me that the dictionary does not contain that or something.

I was trying to figure out how to convert a string (that the user would input to the program via a textbox) into actual code for the program to compile. For example, if the user was to enter: (5*100)+(20-3). How could you take that inputted string, and have the program solve it and return the value?

I have a combobox that pulls a list of values from a database. When a new entry is entered I want an entry in the combobox to read "New record". However, from what I have seen I can only insert and object, such as a DataRow, into the combobox. Is there anyway I can convert a string to to a DataRow, or some other object and insert it in to the combobox? I know there is I am just rusty on my vb.

I'm trying to convert a chosen color into hex base 6 to save to a config file for later use, and that part works, but when converting back to integer to use for a color, it gives me an error about incorrect base.
Dim hex_color = System.Drawing.ColorTranslator.ToOle(ColorDialog1.Color).ToString("X6")
Dim color_int As Integer = Convert.ToInt32(hex_color, 6)
Panel1.BackColor = System.Drawing.ColorTranslator.FromOle(color_int)

I was trying to convert from Double to String and everything working fine. But when I tried some bigger number with fractions in it. I got the number but rounded. I tried something like that:
Dim dd As Double = 1235212435.3453636
Dim str As String = dd
MsgBox(str)
But what I got is 1235212435.34536 instead of 1235212435.3453636

I've got a richtextbox but want to check the keypresses before they come in the textbox. So I thought of using the KeyPress event from the form, checking that key and than writing it to the richtextbox with the Text property.But the KeyChar is a char while the Text property expects a string, and when I convert the KeyChar to a string(ToString) it gives a error.Does anyone know how to fix this or has anyone another idea for checking the presses before writing them?

First: Ok so I'm trying to do a project in my beginning VB .Net class. We are supposed to be taking information from 5 different sections of a form and store them into an array and then call upon them later. We have Name, Address, City,State, and Zip. How would I go about saving the information into an array and then calling upon it later through File IO?
Second: I'm having a problem converting my string into a decimal. Whenever I calculate the price of the order I get 3-4 decimal places. Here is a little snippet of my code for the this:

I have dimmed pricewithout tax as a decimal and stateselect as a string. The stateselect is based off a drop down list.

I've been up for nearly 24 hours now. Trying to program an application for a game I have been playing.I've run in to a problem, I'm not sure how to solve.I have basic knowledge when it comes to VB (college class) so bare with me.[code]My only Idea would be loops to figure out where each of the edited numbers are in the array, But I was looking for something simple.Also, would it be easier to work with the bytes rather than edit them in string form?
