I want to write a regex to verify inputs. The inputs have the following format:
N. Crystal
O. J. Faucon
A. V. E. David
"^[A-Z. ]*+([a-zA-Z])*$" is not working. How can I match the above examples?
I have several text boxes which a user is supposed to input a numeric value and the program will use an array to verify whether the input in each text box falls within the numeric range allowed for that text box. So one text box will only accept number 3-7 and i'm supposed to create an array that will verify the input in that text box falls within that range. Personally, I would just do:
Dim intInput1 as Integer
intInput1 = CInt(txtInput1.Text)
If intInput1 >= 3 or <= 7 Then
messagebox.show("Input Verified")
Else
messagebox.show("Input must be a numeric value between 3 and 7")
End If
But this isn't what the assignment asks.
I'm looking for regex to verify a correct domain has been entered into a textbox, it must have http:// conditional www. also must verfiy it has a TLD but must except TLD in this format to: .com.au, co.uk etc etc
Example of the regex i would like to outcome is [URL] or [URL] no trailing text like index.php
I want to select a random space in a string and replace it with a word (%word%) but there is a problem. The position cannot be fixed as i want it to be inserted at a random break. Few things which iam considering :
1)break the string at a space and merge it with the word
2) find a random space and replace it with the word. I like this point and so far all i have is break the selectedtext into string array and then iterate over each line. But i don't know how to find a random string position? Any short and sweet code please?
If (rtfArticle.SelectedText.Length > 0) Then
Dim strArray As String() = rtfArticle.SelectedText.Split(New Char() {ChrW(10)})
For Each str3 As String In strArray
[code]....
How would i get a certain text inside a textbox to equal that text space to space or null to space?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If Textbox1.Text.StartsWith(Textbox2.Text + " ") And Not String.IsNullOrEmpty(Textbox2.Text) Then
Textbox1.Text = Textbox1.Text.Remove(0, Textbox2.TextLength)
Textbox3.AppendText("a")
End If
Btw: after i finish this step my project will be finished!
I am having an issue where I am using regex.Replace to replace part of a string. The basic idea is that I want to capture the beginning of the string then replace the end of the string with a value from code. For an example pretend I have a string that says "Test Number " followed by number and I want to increment that number. I capture the "Test Number " but when I try to concatenate that capture with the new number it treats the capture ($1) as a literal and replaces the entire string with $1[new number].
[code]...
This will output "We are on Test Number 2", as expected. how I can use a variable in the replacement string portion of the Regex.Replace when including a captured group?
I am using a picture box. I want to be able to use the Space or Enter key to change the image in it. For that, I try to use the keydown function as follow:
Private Sub ChestWindow_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
Select Case e.KeyCode
Case Keys.NumPad1[code]....
is the function which changes the image. It works well when I press '1' on my numeric part of the keyboard as a test.The issue is that when I press Space or Enter, the form containing the picturebox closes. (I've already put the keyPreview property to True)

I'm creating a program in VB.NET to output multiple images. Some images will have the same file name. If there is multiple files with the same name I want to add "_1_" to the end of the file name.

So for example "filename", filename_1_", "filename_2_", etc. Here is the code that I have tried

I've been working straight since yesterday trying to get this to work. I'm a noob to RegEx and I've tested out about 5 different RegEx "builders" but each of them require you to navigate through the options to build the Regex...each of them has failed when I try to use them.Is there an application out there free/paid where you select the line you want to grab and the RegEx is auto generated from that highlight rather than having to try to build the line of code?

View 6 RepliesSo basically, my program is going around the world, and it has come to my realization that certain places use commas instead of periods for decimals points. So herein lies my problem. If the computer's local language is German, then the program will accept commas, but then errors are produced with periods, and vice versa with an American computer. So my question is, is it possible to make the program permanently use periods, and then have a function that can convert any commas to periods?
View 30 RepliesI'm working on an app and in the textbox field I would like to be able to convert anytime a user would type .36 it would actually change and display 0.36, mainly I want it on the key press of the period just add a zero before it, and I need this to happen on the keydown event.. anyone have any ideas for me on how to do this? This is all I know so far...[code] One last smidget of problem too, I only want this to happen when the user types . in the beginning not if he types 4.22 with the period being after a digit.

All the above works, however I wan to add the items to a listbox that are being uploaded. So if I dropped 3 items there it would look like :
