View 3 RepliesHow do I check to see if the first character of a string is a number in VB.NET? I know that the Java way of doing it is:
char c = string.charAt(0);
isDigit = (c >= '0' && c <= '9');
I'm scanning through all characters in a textbox. Then the program counts how many of each character is in the textbox. Here's the code which adds all characters to a list:
For each c as char in TxtBox
list.add(c)
Next
Everything's working fine, except this will also add returns to the list, which I don't want. I thought I could write like this:
If c <> chr(10) Then
list.add(c)
End If
How can I count the amount of times a character appears in a string?
The assignment is to create a program with 2 text boxes, label, and a button. We then need to type a phrase into the first text box, and a character in the second. Then click the button and then the label will display the output of how many times the character in the second text box appears in the first.
I have all the above setup except for how to display the amount of times the character appears in the first text box, here's a picture:
I want to user to enter only numbers and characters in textbox i.e no special charaters.I don't want to use key press event of textbox.As i need same validation in gridview.
So i want to validate whole string.
I am trying to count the number of times a specific character is in a string. The problem is when I run the program the letter doesn't advance from "d" in the string "debugging" and doesn't display the number of time the character "g" is found.
Private Sub Button2_Click(sender As System.Object, e As System.EventArgs) Handles Button2.Click
Dim letterCount As Integer

How can I generate a 7-digit random number and special character string in a textbox on a button click event, in VB.Net?
View 2 RepliesI am kind of new to Visual Basic and I got stuck doing a sample Windows Form program. I was trying to write a String into a text file. But I just couldnt get the command for the new line character whereby each time, the new String is concatenated to the next line instead of the same line. I know that in C the new line character is used. But what about in Visual Basic?
View 7 RepliesSo I am calling an API written in VB.NET from PHP and passing it some text. I want to insert into that text two linebreaks.
I understand that in VB.NET, the character codes for a linebreak are Chr(10) and Chr(13). How can I represent those in PHP?
This is what I have, but It doesn't work with strings for some reason (only text files):

For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.
I am writing a hangman type game and I am displaying the word to the user in a label as all *'s, but I cannot figure out how to have just one of the *'s changed in the label to the correct letter when the user inputs the correct letter into the text box and clicks the check letter button.Everything else in the program works perfectly, except for this part.[code]When I use the .Replace it changes all of the *'s to the correct selected letter.

View 2 RepliesI've been working with the substring command and after coding up all the things I needed it to do, I saw a post on here where the "For Each" statement was used basically to do the same thing.Lets say we just want to take a string apart one character at a time and add each character to a label. Which would be more efficient?I made a cheap example to show ...

My issue is that some websites only allow say 15 characters maximum to be used to create a user name where other sites do not. Currently I have one text box on the screen and a button, and a web browser that navigates to two sites.Site #1 has a cap of 15 characters max to create a user nameSite #2 doesn't have any maximum amount of characters to use.I am wanting to know how I can enter lets say a 20 character username into the text box and have the code set a max of 15 characters for site one and nothing for site 2. I was thinking that this could be done when passing the information from the text box to the text box on the screen with something like
Textbox1.Text.value.length= maximum 15
Site #2:
Textbox1.Text

for Types, we could call toString and convert that into a String, but i would like to do the reverse i.e getting a Type object from its string.
