I have this text box that does a command when ever the text in it is changed. What I want to do is when the length of the textbox reaches >= 27 that it will not add that character to it, so I guess it has to delete it.
Here is my code.
Public Class Form1
Dim WordLength As Integer = 0
Dim StartIndex As Integer
Dim CurrentWordLengthLetter
We have some code in the textCahanged event of a textbox. We only want to fire that code if the user types into the box, not if we change the text in the box programmatically. Can I detect what caused the text to change?
Basically I want to have a textbox (TextBox1) that when you enter an area code (ex. 512) that it will return the state (TEXAS) in the label (Label1). One way that I had been trying before was to reference from a text file the array that I am using which happens to be in the format of 512, TEXAS.
Sample - TextBox1: 512 Label1: Texas
[Code]...
I would like to use this for multiple area codes and have been unsuccessful in getting it to work.
I have a TextBox control being used to capture an IPAddress from the user.I want to be able to allow them to change that IPAddres at which point the new value will be utilized by the appropriate .NET socket class to ping that new address.What other event is used with TextChanged to indicate that the user is done making changes to the TextBox. The Leave Event?

I have added two text boxes - both multiline.and I have the following.vb Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
Windows forms Application. VB .NET 4.0 In my application I have a global boolean variable that keeps track of when changes are made and when they are saved called changesSaved. On closing even it checks the value of this variable before closing the window.. I am using textchanged event to automatically change the value of changesSaved to FALSE when text is changed.. Problem: The group box items are being populated dynamically so the user can edit the values or simply just view them. This dynamic population is causing the textchanged event to fire because the program is changing the text value of the box to put the values in that are stored in the database. The textchanged event should not fire unless the user him or herself enters a value or values in the text boxes..
Is there a way to specify the source i guess you could say for the text changed event or another way so that it will only fire when the user inputs information.??? Functions are as follows: The first is called by the load event to place the values in the box... The next one is the one that is being called as a result of the first one and is also the one that is causing the problems.
I am new to Visual Basic and I am simply looking to remove some text (an example below) from a text file. I have lines of text throughout the file that contain paths to other "different" types of files. I am looking to remove any text between "/" markers inclusing the markers themselves. such as "/path/"Everything I have come across list a streamreader and a streamwriter that list two different files and bla bla. Inst' their a simple readfor.(txtFileLocation.Text).remove"/*/" save file overwriting the original? [code]...
Is there a way to find out if the "TextChanged" event is fired because the user is typing into a textbox or the programmer called myTextBox.Text = "something"? I don't want to react when the user is typing each letter into the textbox so I am using the "Validated" event to catch when the user is done so I can react. The problem is I don't have a way to catch when the programmer does "myTextbox.Text = "something". The only way I know to catch changes there is to use TextChanged but then I don't want to be reacting when the user is typing each letter into the textbox.
All I would like to do is remove one character from the line of the text file that I am reading, which is the first character and also prevent the program from crashing if no text file is present.Here is the code. Can anyone notice where I am going wrong? I thought the "if" statement would cover the crash but it didn't. Clueless, but sort of have an idea on the character removal.

I have a serious problem, I have 3 listboxes, and all three of them will get items that contain no text. My problem is that I have the same code for all three listboxes to remove "" from the listboxes except one listbox will not remove the items. I've tried countless times to remove the empty items and failed. So how do you see if a listbox's item contains no text?
I have this code but it deletes all of the instances of the text, so what would I use to simply delete the selected text after it's been copied and only that text? I've tried using the replace and remove but my methods with those arn't working.[code]...
I have two text files. The fields in each text file are separated by a space (" "). Some of the fields in column 1 of file 1 match the fields in column 1 of file 2. However the third column in file 2 is a numeric field. What I wish to do is check every field in file1 against the field in file 2, and if the number is 1 then remove the row from file 2, if the number is > 1, then subtract one from it.
I have the following coding so far.
Dim lines1 As New List(Of String)(IO.File.ReadAllLines("File1")) Dim lines2 As New List(Of String)(IO.File.ReadAllLines("File2")) Dim values As New Dictionary(Of String, Integer)()
I have text like this format "term: 156^^^:^^59 datainput" Or "term: 156^^^:59 datainput" or "term: 156:^^^59" The "^" represented white space. Notice the white space between the the two numbers and the colon. There 2, 3, 4 or even 7 white space between the two number. I want to remove these white space so that the text can be in this format:
I am trying to remove all spaces from a text field when a form is submitted so that the contents of the post code field match those in a database...
If drSet5c.Tables(0).Rows(0).Item("post_code") = UCase(Replace(tbPostcode.Text, " ","")) Then response.write("Postcodes match")
[Code]....
So if the postcode in the database is AB12CD and the user types AB1 2CD the space is removed on submitting the form and the match statement shows. This is not working though.
