Convert From String To Numeric In Sql Command Text?
Sep 30, 2009
I have an application where the user and search the database and return the values from it. They can also figure the Average, Median, and the Standard Deviation from it. BUt I have a problem with this since the business rules won't allow the result column to be anything but a string so now I am getting error messages on the Select commnad text since it is trying to perform the calculations. I am wondering if there is a way to convert the values in the command text to a numeric value then perform the calculation. Here is the code I am using at the moment.

I have encrypted a string to something like this:
1. Asak2$)kla1015QAXKFskfa332aSJ2(Ska@Skljcmcel3p.lq,aowpqaskla2@)Skx.:Pdm^),dfs;
what i want to is convert this string to something like this
2. JXK2LB AP2WXB S1P0XE ZXPA3H X1LAKW DOXPS3
both 1 & 2 the above strings are fictitious (i made them up to make my point clear)
I am trying to make a licensing system for my VB 2010 express application. (2) above will act as a serial key which can be derived from (1) which is an encrypted form of something unique of the client computer.
I will then confirm the (2) from the client.

I want to upload a string using the UploadString command to a Text file on my FTP server, It uploads correctly but everytime I have the user submit a new string, It overwrites the previous one and displays only one line of string.
I want the person to be able to Submit one string to the text file, then when another user submits another string ( A new line of Chat ) to the text file, I want it to be on a different line after the previous one submitted. Without it being overwritten.
Here's the code I have so far.
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
'button is called Out.

I'm working on a licensing system for my application. I'd like to put all licensing information (licensee name, expiration date, and enabled features) into an object, encrypt that object with a private key, then represent the encrypted data as a single text string which I can send via email to my customers.
I've managed to get the encrypted data into a byte stream, but I don't know how to convert that byte stream into a text value -- something that contains no control characters or whitespace. Can anyone offer advice on how to do that? I've been researching the Encoding class, but I can't find a text-only encoding.

I have lines of text that contain "degree symbols" (ASCII(248)). I want to replace those symbols with an alphabet character (Z).I am changing the line of text into a charArray,iterating through one character at a time. How do I define the ASCII(248) in code to replace each occurence with a Z? Something like string.Replace(ASCII(248), "Z") would be nice, but that doesn't seem to work too well.

i'm using Regex.Split to convert a text file's string to System.Array. The end result is System.Array of 211 strings.
Now what i need is to convert System.Array to a Byte of 211. How would I accomplish this?
System.Array to Dim x(211) as Byte?? Sample code would be great here. I've already visited many sites on this subject with no luck. code below.

I know Val() is a VB6 function, but one thing I like about it is that you can wrap a string in it and it will "extract" the numerical value from the string if there are other things present (i.e. Val("123 Main St.") returns 123). This is the way my teacher taught us to use it. I know about the .TryParse and .Parse methods of the different data types, and how those can be used to check for a numerical value, but is there a replacement that can strip any non-numeric value from a string to put it in an integer (or double, single, decimal, etc.)?

is there a way to check if a string contains characters other than numeric? ive used isnumeric quite a bit and its pretty usefull, but cant find a way to check for text in a string. Having searched around theres a few ways of doing it slowly that ive found using an array of letters and a loop / instring, but thats much more hassle than checking for numbers, so strikes me there must be a way.

ophnField.Text.Trim = "0" Or Val(treeField.Text.Trim) > 0 Or treeField.Text.Trim = "0" Then

I used a regular expression, which handles both numbers and letters in strings of arbitrary length, in one line of code.
dim rtn as String = Regex.Replace(input, "..", "$& ")
I'd like to take numeric strings of arbitrary length and insert a space every 2 characters.
So 1233456 becomes 12 33 45 6. Is there a way I can use format as string or IFormatProvider, like? That would put a limit on how long the string could be though, right? Since I'm casting to a long.
CLng((input)).ToString("## ")
I'd like to take strings of arbitrary length and insert a space every 2 characters.
123dssas4rr should become 12 3d ss as 4r r
