Duplicate Text In Textboxes?
Feb 17, 2011
I have a form that contains an array of textboxes that are created at runtime. 72 to be exact. They will be used to hold the serial numbers of parts that will be be read with a scanner. I need to check that there are no duplicates in the serial numbers while the operator is scanning in the parts and then change the backcolor of the matching textboxes if the text is the same in 2 or more.
I tried this and it doesn't work
Code:
Dim j, k As Integer
Try
For j = 0 To 71

I have 50 Texboxes.
I need to count the number of duplicate entries, and provide a summary (count) for each product code. This makes it easier when the order needs to be placed, and the user don't have to count each value manually.
I have tried looping through all 50 boxes to no avail. This seemed easy, but, clearly I am to thick to think of a solution.

I'm trying to select all nodes with text that contain a certain word (ex: Company) because the word needs to have a register mark.
Here is part of the XHTML (this <p> is inside a table cell).
<p>
<strong>
<a style="color:#0E5A8B; text-decoration:none" target="_blank" href="http://www.trekk.com">
[Code]....
My goal is to just select the 2nd one, the <span> tag and am not sure why <p> tag is also being selected. If it selects <p>, but why wouldn't it also select the <strong> or <a>, and why not the <table> or <td> that contain the <p>?

I am adding line entries in a .ini file. The problem is, I am creating duplicate lines in the file, which I do not want to do. I searched this issue online, and the consensus is to use an array, loop through for duplicates and create a new file. However, being so new at this and teaching myself how to code no less, I am at a dead end. This is not a school project, it is something I am doing for work on my own time. I have all of my code done for the program except for this last step.

I'm having a problem with loading two text boxes from a saved text file. I've built a log in form that saves the user-name and password on separate lines in a text file.I have a save button and a load button. My problem is that I'm new to Visual Basics and I can't figure out how to get the two lines from the file to load into their separate boxes on the form.The code that I have loads both lines from the text file into the User Name Box.Oh the username is on the first line in the text file, and the password is on the second line of the text file. Could someone please help! My Loading code is:
Private Sub btnLoad_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLoad.Click
If File.Exists("Login Config.txt") Then
Dim ioFile As New StreamReader("Login Config.txt")
Dim ioLine As String ' Going to hold one line at a time

I'm having some trouble getting my button to erase the text that is in the textboxes when I hit it. I thought it would be something like txtAnswerText.Text = "" in side of the Next1_Click sub but that didn't do anything at all.

I have this program I'm working on, and I was wondering if it was possible to disable/enable TextBoxes when specific words are wrtten. I tried doing this, but it errored. I'm a new programmer to VB, I just started a month ago, and I'm doing this for fun.
If TextBox1.Text = "Shutdown" then TextBox2.Enabled = True
I also want it so that you don't have to press a button to identify if it is the right text, so it could "scan" automatically.

In my form, A user can do some stuff on my program which will create a new tabpage with a text box on it. The user also selects the name of the tab, which is then the name of the textbox with a "2" on the end of it.
What I need to know is how to get the texts from however many tabpage's textboxes there are and combine them into one textbox, as a sort of receipt.
What I was thinking, because I have this method of removing all the tabpages, is using a code like the one below maybe to do the job, not sure how I would alter it to work though. [code]...
