i'm looking for a VB code to format integer into 5 digits and then after that auto increments like (00001 , 00002, 00003) And they are used in a text box field.
Scenario Example : When the user clicks on Add New Record. The empty id text box field will automatically insert a number 00001 on the textbox and if there user wants to add another record the number goes 00002 and so on.
I have a textbox that is filled by the method [code]...
View 3 RepliesExcuse me if this question already have been answered somewhere else but I really need to know.I need the code to take certain digits out of an intiger, for example:I have the integer 3002010 I want to put the 2 last digits in another integer.Then I want to put the 20 in another integer.After that I take the first digits which comes before those.
Another example:
I have 2993064 In integer one it should be 64 In integer two it should be 30 In integer three it should be 299
I need to count the number of digits in an integer input by the user. In other words if the user enters 101010, I need to obtain the value of 6, because there are 6 digits in this number
View 3 RepliesCan someone give me code to do the following.if the integer is 1-9 display a string 01,02,03 etc.. if 10 or over leave it as is.string display = yourInt.ToString("00");
View 6 RepliesFor some reason I can't figure this out. Here's my code. colorTextbox.Text =Format(Hex(ColorBox.Color.G), "00")What I want it to do is format the Green Hex number to be "00" instead of just "0" when the color is something like blackhis has proven to be very stressful and this Format command makes no sense to me anymore (worked differently in 2005).For one, whatever I put in the quotes ("00") is what comes out in the text box. Butaccording to the command parameters, "00" should be the format, not the actual text! So then I tried any string format I could think of (## etc.) along with switching the order and I STILL can't figure this out.

View 2 RepliesIs there a format string to format a decimal to 000000000,00. So first 9 digits, right padded with zeros if needed; a comma as fraction separator and two fraction digits.
0 => 00000000,00
12 => 00000012,00
987456,456 => 000987456,46
So something like myDecimal.ToString("D9") together with .ToString("F2").
I am trying to mkae sure that there has been 16 numeric digits entered into the masked textbox. If not show errror message and if so to call the fucnction ValidateLuhn. When calling Validate Luhn i want the program to tell me if the number entered is valid or invalid using the code in the function:
Private Function ValidateLuhn(ByVal value As String) As Boolean
Dim CheckSum As Integer = 0
Dim DoubleFlag As Boolean = (value.Length Mod 2 = 0)

Given a texbox, how can I completely ignore non-digit characters? So if I press "A" or "Z", those characters would never appear in the textbox. I'd like to run a bit of code if the user tries to input digits and if he tries to input non-digits too..

How do I split a 2-digit number from a textbox and put the first digit in one label and the second digit in another label when a button is clicked?

another label will show the second digit. I know the button control but I don't get how to get the label to say what the first and second digit is.
I'm trying to match a string to see if it matches exactly this:####-####, it has to be 4 digits followed by a hyphen followed by 4 more digits. Right now I have this pattern: "d{4}-d{4}" but it's allowing 5 digits in either (or both) instead of strictly 4 per group. Here's an example of what it should allow:
1999-2000
2003-2007
2009-2010
and here's what my pattern is allowing but should not be allowing:
20081-2009
2009-20101
12345-12345
12345-1234-1234
