I would like to convert for example the string "98" to the integer 98. Also, is there a way to specify that the value contained in the string is in hexadecimal and that "98" gets converted to 152?

View 8 RepliesI am working on a form of copy protection for some software i am developing. In order to generate a unique license for a machine i am aquiring information about the hardware the software is running on. For this task i aquire the 'BIOS version' of the machine using the Win32 libaries. As the BIOS version format can vary from machine to machine i need to be able to convert a string value to a integer so i can perform a mathmatical calculation on it.
A typical BIOS version output may look like 'GBT42302e31' for eg once all the spaces and characters are removed. However this output can change dramatically between motherboard manufacturers.How do i convert the value 'GBT42302e31' to a integer like '5356243' for eg so i can then perform a calculation or hexidecimal conversion on it?.
I have tried the following and they all fail with numerous conversion errors:Cint Convert.ToInt64()
I got to a snag recently in the program. I know exactly what is going wrong, and I know exactly what will fix it. However, I do not know how to code what I need.

So as you can see, I need to convert a binary string into an integer so it will work properly. Everything else is fine, I've tested it out a lot and done a lot of debugging, even manually, and I'm sure everything will work. All I need is the code to convert it.
I'm trying to get a combobox that has a string value in it to be an integer value. So that I can do math with the value that comes from choosing its indexes.The two strings are "one dozen" and "two dozen" of which I am trying to let VB know that they are actually 12 and 24 respectively so I do the math. How do I declare the variable(s) that becomes the selection of this combobox so visual basic does it right without and error?
This is the code I have so far, with "bagelquantity" and "bagelquantitystring" as the proposed method to work with this problem. I'm thinking I set a variable for the strings of the combo box (bagelquantitystring) to be converted from string to integer into this variable, and then a normal variable (bagelquantity) for the rest of the combobox values.
Private bagelquantitycount As Integer
Private totalsales As Double 'accumulator for total sales LIKE totalsales += totalsales

Is there an easy way to do this in .NET.I see the Convert.ToXXXX, but no Convert.ToBinaryString.
View 2 RepliesThis is my first time posting on the site, but I have found it very helpful in the past. I'm a self taught VB.NET developer and I have run across two questions.1) I'm working on a clients site to add a dynamic billing amount that is determined on what drop down list value is selected or what string gets input into the text box. I'm using nested case statements for this since it seemed a little easier, I'm also using two string arrays to hold my variables for use later on. Here is my question, since I am using strings for my variables do I need to convert them into integers to add them? I know the amp sign "&" is used for combining strings and whatnot, but does the plus sign "+" add the values together or combines them? I know if I convert the string to an integer then convert it back to a string that it will cause more processing to be done and I don't want that. What would be my best option in this case?
2) As for my second question, what's the best way to find an exact string? I have used InStr() before for small checks and it works just fine. But I was wondering if using str.Contains() is better suited for this task. From my understanding, InStr() looks for a relevance of the string you're looking for and str.Contains() looks a little more closely to better find what it is you're looking for. The reason I need to find an exact match is that if the user inputs 10 in the textbox, the code won't give them the price for 1. I have 4, 6, and 8 defined in the drop down list so I'm not worried about those. Would adding pound signs "#" around the string I'm looking for help narrow it down to only what I want?
As for the code, it's not completed. I just started it and began wondering on what was the best way of doing this. Private TUITION_COST As String() = {"900", "1800", "2700", "3600", "4500", "5400", "6300", "7200", "8100", "9000", "9900", "10800"}

Convert String Variable to an Integer?
I tried this[code]...
I have a string
12 | Something Special
I would like to cut the "12" and convert into integer (I need it for SQL query purpose)
I tried:
Dim strID As String
strID = "12 | Something Special"
Dim IntStrID As String[code]....
but I tried "" still did not work
I need to work with a loop, from my understanding a loop takes an original number and performs a mathematical operation until it reaches the goal that you set IE: do until >= (variable). I am trying to make my loop add the numbers in my string then decide what to do from that sum. I am trying to make a game of blackjack and if your 2 dealt cards >= 17 then a my message box appears. If they are not >= 17 then it will add my 2 dealt cards which are rand1+rand2 and then add card that gets drawn when I click my hit button and decide then decide if it is >= 17 If hitting causes you to go over 21 a message box will display saying you went over. My error message shows as cannot convert string to integer (10 2 4). I want those numbers to be added together.
Public Class Form1
Dim presentvalue As Integer
Dim randomcard As New Random()
Dim blank As String
Dim rand2 As Integer
[Code] .....
I think I should start my loop here and have it be something like blank + cardrnd but I do not have the correct formula and I was checking to see if it added correctly by using an if statement.
'test for adding the number string
If CDbl(blank) >= 17 Then
MsgBox("Do you want to hit on " & CInt(answer) & "?")
End If
'Do Until blank >= 17
'answer += cardrnd
'Loop
End Sub

View 2 RepliesI'm trying to convert an integer (0 to 255) into a 2-value hex string. For instance, if the integer was 255, the hex string would be "ff", if the integer was 15, the hex string would be "0f". The issue I'm having is trying to keep the leading 0. I've been able to overcome this by using an if statement to determine if the length is less than 2, in which I would concatenate a 0, but this is pretty inefficient I think. Here's my
Dim get_integer as Integer = TextBox1.Text Dim hex_value As String = Convert.ToString(get_integer, 16)
If hex_value.Length < 2 Then
hex_value = String.Concat(0, hex_value)
End If
how to improve this? I really would like to get away from using the if statement.
I am currently looking into the conversion of a string value to an integer. Obviously I will need to do some validation as to whether the passed value is in fact convertible to an integer.
At the heart of my question is this: the users' local is nl-BE (dutch (Belgium)), which means that we use a comma as decimal sign (and points as thousands separator); e.g. 123.456,78 would be a valid nl-BE number. Now, when using the numeric keypad, the
decimal key will yield a point, not a comma (weird huh!). So many user will enter 123456.12 and when converted to an Int, this should yield 123456.
The thing is that I want to cover all possible angles; both points and commas may be used as decimal sign by the users. So I wondering if anyone has written some code that deals with such a situation. I was thinking of an extension method that makes the
conversion based on whether a point or a comma is last used in the passed string (since no thousands separators should occur after the decimal sign).
I am trying to read and write values in registry. I get return something like "system.object"{string} from reading function. I need to assign the value to a integer variable.
