The following solution should allow the user to enter 'colors' to a combo box; however, if the color is already entered (in an upper, lower case or mixed case format), then the 'Duplicate Color' message should be displayed. I get the message, but my color is also being converted to an upper case format in the combo box.

I have a program where you have three entries, CD name, artist, price and it goes into a listbox and .txt file when closing. I have to have a message box if you enter the same CD name. I have a code to open the .txt file and compare strings but I need to change it to compare only the CD name and not all three entries. Is there a way to do my string compare against my listbox without opening the .txt file?? The program loads the listbox from the .txt file when opening. Private Sub btnAdd_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAdd.Click' adds CD information to the list box
' declare variables
Dim strName As String
Dim strArtist As String

How do I prevent a duplicate entry from a text field by using SQL Query?
View 3 RepliesI've read through all the search results for this and haven't quite got it yet. I often get given Excel spreadsheets of file names and have to check through them for duplicate names.I am making an app to do this for me. I've extracted the data from Excel I'm just having issues with checking for the duplicate. I've tried 2 different ways I found online and neither are working for me,

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've a question to ask about what kind of the vb.net command suitable to use apply to get the duplicate serial number in notepad?
Ifstrdata.Contains(txt_sn.Text)
Then
if strdata.contains(txt_sn.text)> 1 then --> is this command valid to find those record more than 1 in notepad?
msgbox.show("Duplicate entries was found")
My program is half a formulator, and half ordering system. Where I get stuck is the ordering system part. In one screen I have 5 check boxes that you can check for which products you want to order. The products you checked then get sent to another screen and put into a list box with a quantity variable that starts at 1 attached to it. Now, if you check the same product again, another time through the program, as of now, quantity accumulates to 2, which is good, that's what I want. My problem is I want quantity to keep accumulating, right now it accumulates to 2, then on a third pass through the program,it duplicates the entry, so now in the list box has the original product and quantity of 2, and another entry that has the product with quantity of 2. 't quite understand how they work. Here's the code:
Option Explicit On
Option Strict On
Public Class OrderRequest

I'm using VB .NET and I know that Union normally works ByRef but in VB, Strings are generally processed as if they were primitive datatypes.Consequently, here's the problem:
Sub Main()
Dim firstFile, secondFile As String(), resultingFile As New StringBuilder
firstFile = My.Computer.FileSystem.ReadAllText(My.Computer.FileSystem.SpecialDirectories.Desktop & "1.txt").Split(vbNewLine)
secondFile = My.Computer.FileSystem.ReadAllText(My.Computer.FileSystem.SpecialDirectories.Desktop & "2.txt").Split(vbNewLine)

I need help on improving the performance of a program I wrote some time back. This is the main performance issue of the program below. Basically I need to look through some data that is displayed to a user in a list view and determine if the data is a duplicate of any other data in the list. If it is I need to delete the duplicate before my program continues.The below code does the job just fine, however the list view of data has approximately 30,000 rows of data. Hence looping this list 30,000 to the power 30,000 times makes the program very slow. Note subItem(4) in the data is the "unique" identifier that I later discovered was not so unique....
This was a work around function implemented in the code back when I wrote it (not meant to be permanent). I know that listView is not Ideal to store this much data.how to store the data in a more efficient manner or improve the performance of the Search and Delete [code].....
I am developing a windows service, in vb .et, that launches a legacy application that performs some work. The service acts as a wrapper around the legacy app allowing users to automate an otherwise manual operation.Everything is working great, except occasionally the legacy app displays a messagebox. When it does this the process halts until the message box is closed.
As the service will be running on a server there will be no user to close the message box.The service launches the legacy application in a System.Diagnostics.Process.My question is, is there way to detect that a message box has been displayed by a process that I have started using System.Diagnostics.Process and is there a way to through code to close the messagebox.
Firstly I apologize as my question may seems repeated to you. But I am sure the details will not. I am writing a VBScript in VB.Net to automate some operation in SAP. The script is recorded from SAP. All I need to do is to put this script under a button click event on vb.net. I have done this far. But get stuck at one point. While doing the execution of the script, SAP displays a Message Box with two button labeled "Redetermine" & "Cancel" and I have to Click on "Redetermine" button to make the script run further.
The number of appearance of this message box is not fixed. Some times it appears twice and some times more than twice. My question is "How can I detect the Message Box from my VB.Net application and automatically click on the "Redetermine" button if the message box appears"?

I made an application that writes to a text file in csv format, and on another tab, there is a listbox where the user can click the "View Report" button and it will display the information from the text file in a list box. Right now, I am really pleased with it because I was able to use "split" to get all of the separated values on there own individual lines.Now I am wondering, is there a way that I can display one entry at a time in the list box, and then maybe implement "previous entry" and "next entry" buttons so that the user doesn't have to scroll down through the entries to view them, they can just hit next entry and it will go to the next line in the csv text file and display the information from there? I have tried doing it a few different ways, here is what I have so far for the "View Current Report" button:
Private Sub btnViewCurrent_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnViewCurrent.Click
lblReport.Text = "Current Report"

I have a problem in timers, I want to display 2 forms each one after 3 and 5, how to do that? I mean when the first form appears, after 3 seconds another one will appear, then after 5 seconds the second will appear. I have a code where someone gave me here but its for message box only, thus I modify it to put a form still does not work. Here the code I put in the timer below:
Private Sub frmblabla_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
tmrnote.Start()
Private Sub tmrnote_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tmrnote.Tick[code]....
I still have problem when the message box stops, it displays all the forms together. All I want is when the message box stops, then it display the first form then stop to display the second then stop to display the last. The first form must stay for 3 seconds on the screen, then after 3 seconds the second appears then after 5 seconds the last appears.
I am working on a small VB application that listens for commands sent from an Android app.
One of the functions is to extract an archive. I am familiar with how to listen for the unrar process to finish, so I can display a progressdialog on the phone while the extraction is happening, and clear it as soon as it's done.
BUT ... if there is an error/alert from WinRAR, WaitForExit() never gets called because WinRAR is still sitting there open until I click "OK" on the MsgBox.
For Example ... if you try to extract a file that is not actually an archive... an alert will pop up saying "No Archives Found", and basically everything is halted on the VB app and the Android app, and the Android app just sits on a progressdialog saying "extracting..." until you manually hit "OK" on the computer.
As you can imagine, this is a problem if the whole point of your app is to NOT have to go over to the computer.
So... I am wondering if there is something similar to WaitForExit() that will wait for an error and allow me to close out the alert and let the process end.
Here's my Sub for the UnRar command:
Private Sub UnRar(ByVal WorkingDirectory As String, ByVal filepath As String)
Dim objRegKey As RegistryKey
objRegKey = Registry.ClassesRoot.OpenSubKey("WinRARShellOpenCommand")

I have a Combobox in a Windows form that has a DateTime value as the Display Member and the Room Number as the Value member. When the user makes a selection in the combobox, a textbox is populated with the corresponding room number. There are some instances in the combobox where there are identical Display Member values. When a user selects one of the duplicate values and moves the mouse cursor away from the combobox, the combobox always defaults to the first of the duplicate items.
Example:
Here are the values that are currently populated in the combobox:
Display Member Value Member
02/25/2010 9:00AM 1
02/25/2010 9:00AM 2
If the second listing in the combobox is selected (the item with the value member of 2), and then the user clicks away from the combobox, the value default to Value Member 1.
Is there anyway to keep duplicate display members in a combobox while keeping the proper value member selected?

I want to set a certain column to true or false automatically based on what value another column has entered. I managed to get this working by myself using the 'SQL Pane' in VB and testing it by using execute sql but I don't know what to do now. I assumed that I could just save it and it would work from there but that's not the case, it dissapears from the SQL Pane if I close the project (even though it worked fine when I ran the project the first time), so where do I put it/what do I do with it in order to get this to work?
