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 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
Dim strPrice As String

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.

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 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

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?

View 1 RepliesI have some reports that I use with the MS ReportViewer and I need to get a count of the physical pages (as opposed to logical page count) to use with a print dialog. I've implemented a workaround so the ReportViewer control displays the correct number of physical pages, but is there a way to get that value from the ReportViewer control? The only publicly accessible property gives the logical page count.

ctl.Text = "found the sevens"

I have an app that I'm calling up a 3rd party API.. and on each call I want to store off the patient data in to logs that are like weekly.. so on each call to the API I want to encrypt the data and push as a line into a file..I kinda dont want to open the file.. add in data then encrypt the whole file, that seems like extra work to me.so if I want to encypt the data from string to byte whats the best way to push into a file and then read out.. should I set the string to be a certain lenght so my writes and reads match up ? or is there a way to write to a data file so that it knows the end of the entry ? should I use a type class for this ?
