VS 2008 Cut Text Off After A Certain Number Of Characters?
Sep 13, 2009
Say you have the following string: Welcome to my program!
But you only want it to show a certain amount of characters then "..." so it would look like this: welcome to m...
I'm addressing this problem because I'm making a tabbed web browser and when I create tabs I have the document title as the text, but It looks weird without it cut off, so I wanted to know how I could replace the text after say, 15 characters with

I'm having a very difficult task here. I need to analyze a certain text and find the minimum number of characters it needs to become a palindrome. The text will not have any special characters or numbers, just alphabet letters. Now, I've made some progression and have tried a lot of situations correctly, but in some situations I've gotten wrong outputs on the MINIMUM number of characters needed. I've tested the below texts:

I'm making a custom control suited for handling passwords. I have created a control that inherits from a text box and I have implemented a lot of things so far. But what i want to do now is create a system so that when a user types It will display his last character typed for a X amount of time.Is there a way to turn only selected characters into password characters and still be able to get the password text from the Text property ?

I am trying to do this but it doesn't work:
VB
Dim str As String = "07" & GetBetween("Stephen 0761234567", "07", vbNewLine)Dim op As String = "lol" TextBox1.Text.Replace(str, op)
GetBetween is just a function to match something between something else. That works fine, the string (str) sets as 0761234567 just like I want but when i try to replace the text it doesn't work.

I have a query to solve for which I have coded. But my code produces output only for those hardcoded values found in the text file. I have a text file which is given as the input to my code. The text file contains lines with "_DIA" , "_DIA_some number" etc. In this case I need to remove few letters from that field.
Eg: 1)if the name field contains 1234567_DIA_2.PRT, I need to remove "_DIA_2" from the name field and concatenate the .PRT with the number. 2)if the name field contains 1234567_DIA1.PRT, then remove "_DIA1" and concatenate. I need to store the number of characters removed and add so many number of blank spaces with the name field after the concatenation.
for the 1) case I need to concatenate and add 6 spaces with the name field. for the 2) case I need to concatenate and add 5 spaces with the name field.
I'm not sure how to find the number of characters from "_" to ".", underscore need to be considered in the counting and the dot(.) should not be taken into account.

Say I open a text file in a richtextbox control. After that I search for a specific string like "6.1". The string actually continues like "6.1XXXXXXX". I need to get not just only "6.1", but also 2 more chars after "6.1", like "6.1XX". I will then output this in a textbox, but I can do that, I don't know how to get the X number of characters.

I'm attempting to modify some random password generator code, and wanted to do something a little different. I would like to list all uppercase, lowercase, numeric and special characters next to a text box. In the four text boxes, you would select how many characters from each set you would like in your password. For example 4 uppercase, 2 lowercase, 3 numbers and 2 special characters. That would generate a random password 11 characters long. I can generate random passwords now, and have included a text box which allows the length of the password to be specified, but i would like the granularity of selecting from each set.[code]

I've written a piece of code that takes 3 fields from a database and writes out the 3 added together, but with the middle field cropped down, so that the total number of characters is always 28, what I thought was the width of my listbox. I realised when I debugged though, that the listbox was docked and grew or shrank depending on the size of the screen.
Is there a way to determine how many fixed width characters will fit in a control, at run time?

Is there a function in VB.net that allows me to divide a really long String into a specific number of characters? [code] The length of this string is 18 and I'd like to group it by 3, so each group would contain 6 characters. Is there an easier way of doing this? Is there a predefined function in VB.net? I'm already thinking of doing it manually, like converting the string into characters and storing them inside arrays.

I have a RTB which I import with a set of 7 or 9 didit numbers, 7 for Staff and 9 for Students. e.g. Staff numbers [code]and depending on what is selected in a list box ('Student' or 'Staff') will generate a string to create user accounts. To further error check I would like to check if a line in the RTB = 7 And Listbox = "Student" Then msgbox("Data mismatch between User ID and Account type")

I'm using this code to return some string from a tcpclient but when the string comes back it has a leading " character in it. I'm trying to remove it but the Len() function is reading the number of bytes instead of the string itself. How can I alter this to give me the length of the string as I would normally use it and not of the array underlying the string itself?
Dim bytes(tcpClient.ReceiveBufferSize) As Byte
networkStream.Read(bytes, 0, CInt(tcpClient.ReceiveBufferSize))
' Output the data received from the host to the console.'
[code]....
Len() reports the number of bytes not the number of characters in the string.

For a project I need to do a String strX is said to be a cyclic rotation of a String strY if it's possible to rotate the characters in strY by some number of positions, n, such that strY becomes strX. I don't mean rotate in a Caesar sense here but in a left-right (or right-left) sense. For instance, strX = abanan is a cyclic rotation of strY = banana because rotating the characters in banana to the right by n=1 (i.e., by one position), wrapping accordingly, yields abanan. Similarly is strX = anabana cyclic rotation of strY = banana because rotating the characters in banana by n=3.I need to write an application that returns True if strX is a cyclic rotation of strY otherwise the result is False. I'm looking into how to do this, I know it will involve and if then statement and possibly some loops. Is there anyone who can help me better understand what I should do?

I'm currently building a Terminal Emulator and can read RS232 data ok into a Textbox.
However, I want to remove a set number of characters before each line received.
I've got so far with StringBuilder but my code is wrong somewhere as it cuts out every other line.
The original text looks like this:W 320:15:25 0300 SAMPLE FLOW WARN
T 320:15:25 0300 CO= 4.6 PPM
T 320:15:25 0300 RANGE=50 PPM
T 320:15:25 0300 STABIL= 0.0 PPM
T 320:15:25 0300 CO MEAS=4012.0 MV
