i am trying to put a maximum row number of lines in a multiline textbox. What i want is to achieve something like a console, with a maximum number of rows, with the top rows to dissappear and to keep always the last i.e. 500 rows. a note: for the textbox text i use the following algorithm
dim text
textbox.text = textbox.text & vbcrlf & text
the problem is that after a certain number of rows the program starts to get a little slow. So i guess if i put a limit to the rows i will fix this.
I added a multiline textbox to my form. I only wanted that users can add 3 lines.This code works perfect if i don't add the messagebox. Any ideas?

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
I would like to include the line numbers on the left side of a multiline textbox, much like what Notepad++ has. It should scroll along with the rest. Is this possible?
I have a multiline textbox which is loading from a .dat file. However, despite telling it to load all of the .dat file, it misses off the end. I it copies the first large body of text and a load of spaces that are inbetween the first and second body, but doesn't load the second body of text. Here is the code I'm using to open my file: RichTextBox2.Text = IO.File.ReadAllText("00061530.dat")
I'm trying to count characters in a textbox, which includes newline characters and tabs. How do we know if the textbox contains only newline characters? ie or if the user types in one or more characters, then a bunch of "newline" characters (CR followed by LF) and then goes back and deletes the original one or more characters leaving only the leading "newline" characters. I don't want to count the characters in textbox only if new line exists..
If String.IsNullOrEmpty(TextBox1.Text) Then Label5.Text = 0 Else
I'm using VS 2005, after VB6 to VB.NET conversion we have fixed all the errors but still have unidentified number of warnings.

What is the maximum number of executions in a while loop in VB.net that it will allow? Meaning, it is checking for a variable to equal some value, but that value never comes? How many times will it execute the code before it quits? Is there some way to set the maximum number of executions without terminating it programmatically?
I am new to visual basic. Below is my Private Sub todayMonth_Validating(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles todayMonth.Validating Dim tb As TextBox = DirectCast(sender, TextBox) If Convert.ToInt32(tb.Text) >= 1 And Convert.ToInt32(tb.Text) <= 12 Then tb.Tag = True [Code] .....
Actually, I wanted to validate the todayMonth textbox just to input number between 1 to 12. The problem comes out when I do this procedure : Lets say I input an interger 11 and it passes the validation and proceed to another textbox. Then I click back to the todayMonth textbox, it shows this error : "Conversion from string "" to type 'Integer' is not valid." I don't know why my value in the textbox is "null" or empty . I still saw the value 11 on the textbox.
I'm trying to figure out a good way of implementing a List(Of) that holds a maximum number of records.
I have a List(Of Int32) - it's being populated every 2 seconds with a new Int32 item.
I want to store only the most current 2000 items.How can I make the list hold a maximum of 2000 items, then when the 2001'th item is attempted to be added, the List drops the 2000'th item (resulting in the current total being 1999).
Thing is, I need to make sure I'm dropping only the oldest item and adding a new item into the List.
one of our programmers is having an issue with a asp.net app. i had him rebuild and recompile the app to the network share on the staging server and received the same. i even deleted the files in this folder(C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files). to make sure that the server was not the issue i installed it on another server and received the same error.i found a article on msdn that states that its a source code issue.
Compiler Error Message: BC30041: Maximum number of errors has been exceeded. Source Error: [No relevant source lines] Source File: vbc : Line: 0

Im wanting to use a textbox for the entry of Decimal figures (currency). Is there any way I can have it so if a user does not put a decimal figure (ie 15 instead of 15.00) it will put it on.
