How To Add Spaces To Numeric String Every 2 Numbers
Oct 21, 2011
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

I have a string I want to parse. I could write the code to do so, but I figured that VS.NET has a parser that should do this for me.however, I can't find it. All the searches I do return info on how to parse numeric values in string form into real numbers. It would be nice if the MSDN search had some ways to allow users to enter more details than just search text and 3 ways to filter out irrelevant stuff. In any case, I also tried things like string.parse (nope - although I kinda figured this would be it.) I also looked at Enum.parse, but the code indicates that it works with arrasy of items, not strings.

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.

Is there a way to set a textbox in vb such that it does not accept a space or a non-numeric character entered by a user? I am writing a program that has a textbox called "phoneField" in which the user should type in only numbers and if the user trys to type a non-numeric character or space, nothing should be displayed in the textbox. How could that be done?

I have an issue in VB6 that is giving me a major headache. When using a variable defined as a single data type, VB6 will add random numbers to the number i assign to it.
For instance I have a single variable that is manually set to 0.3. Then i create another single variable and set it to 0.25. I have the program add 0.01 to the second variable until it equals the first. But they never equal. I couldn't figure out why when both were showing they equaled 0.3.

best way to check if a textbox has only 4 numbers and isNumeric, for example i need to enter postcodes.I currently have:
If CDbl(txtPostcode.Text) <> 4 Or Not IsNumeric(txtPostcode) Then
MessageBox.Show("Postcode must be 4 Digits", "Error")
But the message box comes up regardless of whether there is 4 numbers, letters, or anything in the textbox. Its also used in the leave function of the textbox.

I am having dificulties taking a datagrid cell value stored in the following location (datagridVNTPSorted.Item(15), irow).Value) into individual digits to reassign values for counters.
The cell in the datagrid (Listed Above) contains a number between 1 and 5624. I have 4 different counters. If the number was "2856", the counters would need to be updated as follows:
intdirectoryCountDigit1 = 2
intdirectoryCountDigit2 = 8
intdirectoryCountDigit3 = 5

I have a textbox which has a numeric value that changes - would it be possible to check if that value matches two numeric values in a text file? and if the value matches then to display some text in a label? The textfile only has fields displayed like so
Horizontal 55
Vertical 16
So I would only need to check if the numeric field in textbox matches the two numbers in the second column. In the past I have use System.IO.File to create/delete/append to files but I havent come across anything like contains.

I'm realy green when it comes to programming but I like to think I am learning quickly. However, I cant figure out how to generate a number of random numbers baised on the vailu of a numeric slider. So for example I am generating a number between 1-12 where each point of value for the slider would generate an indiigual number that can all be added to a final total. I would also like to be able to back the slider down to a previous number and have the same total I had last time I was at position x. This is what i have so far:

i have string like
Dim Test as String = "abc " & " def"
what above code does is gives is "abc def" as output, what i want is "abc--------def" (where hash sign is spaces i need) i have tried
Dim Test as String = "abc----" & "----def"
for some reason (dot)net only takes it as one single space. check above(1) example ,i gave two spaces but it got converted to one space.
Dim Test as String = "abc" & Char(9) & "def"
doesn't work (found char(9) solution on internet)
Dim Test as String = "abc" & space(8) & "def"
doesn't work I have tried another 10 different option but none seems to be working for me.

I want to be able to find both spaces using the indexof method. Here's my code so far. Basically the program will turn the string "Will Smith" to "Smith, Will" But I noticed when I type in a name with a middle initial or middle name "Will J Smith" I would get "J Smith, Will" And I want to be able to find that second space when its there and apply a code that would produce "Smith, Will J" When there is a second space. How would I go about doing so?

Is there a way to take an integer, say 10, and convert that to 10 spaces? What I've got is a text field that the users enters a number. I then need to convert that number into spaces and insert those spaces into a string of text. I've found several places to convert text to an integer but not the other way around.

lets say I had a string variable that contained "Hello World!", (or whatever the string contained) how would i remove the the right most spaces to make it say "Hello World" (im reading in items from a text file using substrings that has fixed positions with one line of the text containing several different items) or does it automatically eliminate the right most spaces???

I have a string that I need to place to a file, but when I do place it to file, it gets cut off at the space, and the words after the space are placed to a new line. So I decided to place an underbar in place of all spaces, to avoid that problem. So how can I search the string for spaces and replace each with an underbar?

format a decimal value to a string with a single digit after the comma/dot and leading spaces for values less than 100?For example, a decimal value of 12.3456 should be output as " 12.3" with single leading space. 10.011 would be " 10.0". 123.123 is "123.1" I'm looking for a solution, that works with standard/custom string formatting, i.e.
decimal value = 12.345456;
Console.Write("{0:magic}", value); // 'magic' would be a fancy pattern.

P.S. This was a VB6 command line app that I just converted to VB.net & the behaviour only occurs in the VB.net version. It's being called in many places at the moment, so don't really want to have to manually go through all calls & add double quotes around the whole argument.

I saw a built in function in VBscript a while back that converted a string with spaces to an array. However I can't remember the name and I looked it up in a few function listings and couldn't find it. Since almost all the functions that are in VBcript are in VB.NET I was wondering if anyone remembered the name of the function.

i am trying to split a string up into separate lines with the following code, but for some reason it is also removing the spaces in the string.
Dim calculationText As String
calculationText = File.ReadAllText(fileName)
Dim fields() As String
fields = calculationText.Split(vbCrLf)
when i am in debugger mode, i look at fields, and every element has a line of the string but all the spaces and tabs are removed.

I'm implementing a feature which reads comma separated txt file from server(one line at a time). Format of file is fixed, There are 3 columns on each row. After reading the row from file I insert it in a database table. But first value of each row aoutomatically appends two blank spaces, even if there are no blank spaces at the begining of each row. I tried to use "TRIM/LTRIM/Replace" to remove blank spece from the first value of each row, but didn't succeed.

I'm writing a macro to let me replace the spaces in a string in my code file with underscores. I've gotten as far as finding the beginning and end of the string as instances of VirtualPoint. Now I'm trying to select from the first VirtualPoint to the second. And I can't figure it out. I know the VirtualPoints are correct, because I'm using MessageBox.Show to tell me their values when I run the macro. I just don't know the correct command to set the TextSelection from the first to the second. I've tried this: [Code]

I just changed a control on a form from a masked textbox to a normal textbox because I wrote my own code to validate the data. I'm trying to clear the leading spaces that were created for this column in an Access database using the LTrim function and it doesn't work for some reason. The column is " :30" in the table and when I LTrim it and save the changes, it's still " :30" , not ":30". Is that leading entry not a space character?

I have a string which I have pulled out of a text file as shown below,[code]and I would like to split it up and get the numbers into individual string() arrays. I have tried using split , but the problem with this is that it only splits up characters with one space between them, and there could be multiple spaces between characters so it ends up storing blank spaces it a string array.[code]
