I have a listview and on save or update of the database it saves the TicketID to the listview. It also shows all the prior tickets created in the listview as well. I would like to pass the very last entry ie in this case TicketID to a textbox so that it prints out a ticket with the ticketID for the user.
Don't really want to loop through all the other tickets in the listview since it could end up running into the tens of thousands of numbers.
I have setup a page in Excel with several textboxes for data entry. I would like to be able to tab from textbox to textbox so I can enter this data as quickly as possible.

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 need to display all the data in that table but it only shows me the last entry.
db.OpenConnection()
strSQL = "SELECT * FROM BaselineTeam WHERE Process = '" & txtProcess.Text & "' " & _
"AND SubProcess = '" & txtSubProcess.Text & "'"[code]......
I have three text boxes in a winform (.net 1.1).
I am expecting the user to type in a positive number or just to leave it as zero (default).
Is there a way that I can check that the user has typed in a number rathet than letters.
As I am coding it in VB.NET, I would prefer it if any answers where in VB style rather than C# or C++.
I'm trying to add a name of a product to a Textbox...the name of the product is stored in a database. Now there is a Combobox with number in them....1 2 3 ect. Now if you select one of the numbers it must display that product name?

Back on my form with a ton of financial data entry textboxes but I want to have the data formatted at runtime, as I enter the data.I have a format declared as Public Const cFmtCurrency = "##,###,###" ' don't need decimal for the local China currency What would be the least compicated way to have these textboxes (19 of them) format the Long Integer values as I enter the data. I think a Lost Focus event would be silly; there must be a better, more efficient way.Also want to use this format when I retreive records from the db (don't see a reason to mask data in db)
View 7 RepliesI've got a program and what I need is for a Timer (running in a different thread) to constantly be checking a TextBox for an entry that is similar to:Quote"(PlayerName)" has joined the server.Where (PlayerName) would be replaced with the players name in the TextBox. What I would need the TextBox to do after it has found this entry is to add (PlayerName) to a listbox. If someone can help me out this far then I can use the same code to get it to remove the player when they leave.Below is a picture of what it should look like inside the program.
View 3 RepliesOkay, that snippet made the file I was trying to open in the %USERNAME%AppDataLocal folder worked perfectly, again, many thanks - But now I'm 3/4 of the way through my program, and I've hit a wall - I have the exact same program I made in VB6, and it works to perfection, but I am TRYING to switch over to .NET, and am finding a lot of difficulties in getting certain things to work - My biggest headache right now [ Which is basically the finishing of my program ] is a bit hard to explain, so this may be a rather long post: One of my programs that I use to keep track of my Music hard drive outputs to an XML file, in which there is one line I would like to be able to 'Replace' through the program I am making now to a different user-defined string, and close [ Applying string change/save ] the XML file. I have my Main Form, a TextBox1 [ I can't get the XML to open in a ListBox like I wanted ], TextBox2, a 'Locate String' Button, a 'Modify' Button, and an Exit Button. I open the XML file with this in my Form1_Load event into my TextBox1:[code]
The <DateValue> is the line I want to be able to modify [ Which the entire string looks like this: <DateValue>2010-04-10T10:00:03.5009756-04:00 </DateValue>, and I want to be able to change the date and time to whatever the user specifies ], which once the XML is loaded into TextBox1, when the 'Modify' Button is clicked, that string is then loaded into TextBox2... This is where I am lost - How can I apply the modified string to the TextBox1.Text [ Entire XML file ], and save it upon program end, without the rest of the XML lines being disturbed? I realized I needed another Button - The 'Modify' Button now loads the selected string into TextBox2, and I have a 3rd Button to 'Apply Modification', which I want to update the <DateValue> string in the TextBox1 [ Full XML file ] from the modified string in TextBox2, then save on exit - Hope this helped clarify things.So here's the routine:
1. Form loads, opening the XML file, and loading it into TextBox1.
2. User clicks 'Modify' Button to load searched string into TextBox2.
3. User modifies TextBox2 entry.
4. User clicks 'Apply Modification' Button, which changes the searched string in TextBox1 to the modified user-defined string.
5. User clicks 'Exit', which saves the XML changes from TextBox1 [ Without messing up the XML file format ], and the program ends.

I hope someone can help me. I have an ATM machine connected to a server. A form takes a textBox entry as a PIN number and matches it to a card number in the same table which is the primary key. The card number is in a comboBox.Selected Item. I have used a dataset to fill the comboBox as the form loads. I have tried for days and got nowhere.

GridView1 is bound to a View, tblAccounts.

i am pulling together a cash register that will allow both bar code product entry and manual key entry.imagine if you have a tin of beans in front of you, in a small corner shop they would probably type "47" and then hit "Produce". Fairly straight forward as I have the button Produce to act upon my code and update my salestrans.mdb but,if you scan the bar code I want the same form to handle both 'real' actions, (i assume that keyboard emulation barcode scanner includes "ENTER" after providing 13 digits)....
Q. in perhaps a long winded way i want to know how to kick off an event based on the "ENTER" key being activiated by the barcode scanner)?i do not want to have to hit any buttons if i am scanning bar codes.
What is the code for ignoring the case of an entry while checking to see if the entry is correct or not... (i.e. in a flashcard program... given definition, asks for the name) I don't want the case of a character to affect whether the answer is correct or not.
View 2 RepliesI am trying to make a program with a bar code reader for the first time. I am programming with VB 2005. I want to differentiate a bar code entry to keyboard entry. My questions:
1. Does bar code reader generate a keydown (or keypress) event for each of the digits of the entry? For example, if the barcode read: 1234567890, does that mean that there will be 10 keydown (or keypress) events for that single barcode that was read?
2. I have read from the posts that the best way to differentiating keyboard vs bar code input is to analyse the time between keystroke (for less than certain number of milliseconds).
I need to write a program in VB 2008 express that takes an user entry from a textbox and strips out all the spaces, changes it to either all upper case or all lower case then checks to see if it is a palindrome. I must also include a loop structure and a decision structure. I have seen bits and pieces of code but I do not really know how to put them together. Basically I need it from the button click to the end. ?

I have a Listview1 controls on my Form. the controls has 1 column with more lines. First, I wanted these lines into separate columns, but the lines are not delimited, it means, it has 1 ":", and the others ",". So I could write it only in 1 line:
Dim filename As String = "filename.txt"
ListView1.Items.Clear()
Dim sr As New System.IO.StreamReader(filename)
[Code].....
The "channels" is an identifacation from other lines that I don't want in the listview. So I have the line, and I want it to examine, whether it contains a specified word. If yes, then this word should be displayed in a textbox.
How do you get a textbox being using for password entry to display the black circle that you often see in web forms, on the iphone etc etc?
I can change the PasswordChar property to an asterisk no problem and even copying and pasting symbols inserted into Word seemed to work - just couldn't find a symbol that looked like a bullet point!
Can this actually be achieved for a standalone exe, or is it something unique to web forms? Surely copying and pasting symbols from Word isn't actually the answer?

View 2 RepliesI am having trouble getting the Student Name entered in the Student Name Form to change the Text titles of the GroupBox's on the Main Form and Schedule Form. I understand the logic of what needs to be done to some extent, but I am having trouble coming up with the correct coding.
Below is a snippet of the Student Name Form code that I tried most recently just to see if I could get any change to happen to the other 2 Forms when the Accept Name button was clicked. As of yet, I cannot get a change to happen at all in the groupboxes of the other Forms.[code...]
CODE:
That code works to read the entry data and to recognise the correct data, and the incorrect. However, even if entry is correct, the error msgbox will appear (x times of how many records there are in file), despite being navigated to the menu. Anyway that the Else isn't triggered when data is correct. Also for it to appear just one instead of (x times of how many records there are in file.)
I have been searching for an answer for this for almost a week now, and I can't seem to find a way to do this. I would think it is a relatively simple thing...
