I have an assignment that asks me to:
1. create a button
2. when that button is clicked, an inputBox will appear to ask the user how many words they will enter.
3. then display an inputBox for each word.
For example, when the first inputBox appears, I enter "3" (meaning that I will enter 3 words).Then there should be 3 more inputBox (each inputBox allows me to enter only 1 word)After I enter the third word, there will be no more inputBox.How can we FLAG (stop) the inputBox, or let the inputBox know when to stop showing up?

I have created a users database in access and included that database in the bin directory of my project. I have then created a connection to that database using the wizard in 2k8 express.What i need to be able to do is to insert usernames into the users table in the database. I am at a loss of where to start with this problem. Do i need to create a recordset or not? If so how do i write an sql query in VB2K8 to insert data into that recordset and then update the underlying database?

Quick question on the InputBox. I am just learning this, what is the code to "read" commands that are placed from the Inputbox? I can do this in the command line: System.Console.Writeline(), System.console.Readline()
I just would like to know how read the line from the inputbox. Also when I debug my script do I -always- need to have the command prompt in the background?

I would like to kindly ask if there is a dictionary in vb.net?
I would like to validate some data from the user and their corresponding value.
e.g.
2 = ABC
6 = MNO
6 = MNO
7 = PQRS
8 = TUV
8 = TUV
3 = DEF
if the user had input the numeric data on textbox1, then the alpha phrase will show on textbox2.
What i want to run is that if i press the "execute" button, it will look for a word than can be create using these letters ( e.g COMPUTE )
Then it will display the word "COMPUTE" on textbox3.
Is there a function or method i could use to do that?

I would like to know that how am i going to validate the data inside a currency field to see whether its format is correct or not ?How am i going to reload the data when an action is canceled ? For example, when i click the cancel button, a message box will pop up and ask the user whether he/she want to cancel the action. When the user click yes, the action will be cancel and the data inside a database will automatically display inside the text boxes, as if everything is start from the beginning

I have a combo box that contains data from a database.I am using autocomplete to assist users in finding the large amount of data that the combo box is bound to.What I need to do is check the typed data with the values bound to the box.I need to show a message box if what the user types isn't in the list. Right now if its not in the list and they tab out of the box it throws an exception.Is there a way to validate what is typed with the data in the list. I tried changing the drop down style to dropdownlist but this doesn't allow the user to type in data.

In a Windows XP Pro environment, my system uses a mainframe emulator in a window in which a scanning application is running. The data populating the mainframe app comes from various instruments, scales, barcode scanners, etc.. The data inputs are captured by a winwedge type RS232 data aquisition software.
When all the data is processed correctly, the mainframe application sends an "operation completed" message and creates an exclamation system event associated with a specific sound to inform the user.
My goal is to create a MS Access application that would use the Exclamation system event to validate writing the barcode that was just read to a database without further querying the mainframe, creating a local database. I only want to write the barcode when the mainframe application completed and therefore played the sound.

I am working on a VB.NET windows applications. It reads data from a text file and inserts them into SQL server DB using SQL Bulk copy.I want to validate the length of all the fields in the file. The maximum length allowed for evey field is stored in tbFieldLength table. File has 50 columns and 10,000 rows and the values are separated by '|' symbol.
If the length of a value in any row is greater than the length specified in the tbFieldLength table, I want throw an error with exact row and column details. For example,saying
"Lenght of the value in Row 6, Column 20 is greater than the expected length"Also, I want to identify all the places if the error occurs in multiple locations. What is the best way to validate the length of fields in the text file?

I have an application has a data entry form, and currently I'm using the form validation and validated events to validate the data - along with an error provider. I've read that this logic should be placed in the Dataset rather than the form. To that end, i've started exploring how to do that.

Dense student here with little sleep here during finals week...I have a text field being read on a button click event (along with lots of other information being read). This field needs to have a number entered.
I either:
1) Force a default value (i.e. - "2")
2) Verify there's something in the field AND that something is numeric...

So right now it all looks pretty with ... <button type="submit" runat="server" name="subscribe" id="Button1" class="link-button" onserverclick="saveListing"> Until it is time to validate the data before calling saveListing function codebehind (in VB .Net). How can true/false be return so that when true saveListing will be called, otherwise not?

How do you make an Inputbox without a title?
I know you can do it this way:
inputbox("Please answer a question", " ", "")
This way you put a space in the Title property.
But is there another way to do this without putting a space in the Title property?
Maybe there is an inputbox without a title in vb.net?

VB has a function InputBox() that will prompt the user to enter a single value, then click OK. Is there a parallel functionality in ASP.NET, that will get the browser to pop up some kind of input box to return a single value? If not, how do you recommend I achieve this effect?

I have a problem with inserting a multiple selection option into my Inputbox.
IDEA: First the user chooses an excel file which he wants to open and then the sheet he wants to be read.
I can manage everything else except making the sheet selection a multiple option one.
At the moment the name of the wanted Excel sheet is typed into the text field in the inputbox. But I want the textfield to be a dropdownlist which would be populated with this:
With ComboBox1
For i As Integer = 1 To XL_WB.Worksheets.Count
Dim nimet As Excel.Worksheet = XL_WB.Worksheets(i)
[Code]....
how to create an Inputbox with Textfield --> ComboBox ??
