Insert Letter "N" And Have Followed By 4 Digits Is Entered By The User In To The Text Box?
Nov 8, 2011
NOTE: I tried using concat() method, join method and even tried to insert just text(which turned out editable) but none of them worked as I wanted. I was thinking if substring method will work but I only have basic idea of how substring works. I want the letter "N" to be inserted into the text box when form loads and when the user enters 4digits(OrderNo2.text) which should be joined so that it can be saved together when I clicked on save button.

I am a vb newbie having some trouble with an assignment. A user enters a letter into a text box, and the output must make the letter uppercase and tell what position the letter is at in the sentence "The quick brown fox jumps over a lazy dog."
Here is my
Private Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
[CODE]...............
This is what comes out: "A first occurs in position -1". Everything comes out except the position is always displayed as -1.

I have a datagridview and, I know I am a bit weird, but when believe it or not, when a user enters a new row I want to insert that row in the database. And even weirder, when a user changes a row in my datagridview I want to update (imagine that) the database.

I have been struggling with getting FormViews to work the way Microsoft expects me to for about a day and have figure a bunch of great stuff out.
I can catch e.Exception and e.ReturnValue in the ObjectDataSource.Inserting Event Handler and I can even cheat and check other properties of the Object in the ObjectDataSource.ObjectDisposing by checking the e.ObjectInstance ... and I even learned that FormView's Inserting Handler Runs AFTER the ObjectDisposing Handler so If there is a problem found I still have time to react to it and st the e.KeepInInsertMode to true on the FormView.
My problem is, it seems that the values entered by the user into the Insert form are cleared regardless.
So, How do I Prevent a FormView from clearing after it's Insert Method has fired?
(Using ASP.NET + VB)
I don't think posting my code here will really do much good and i would have to modify it to trim out confidential business logic stuff... so I'll skip it for now.
edit:
I have found a temporary and admittedly terribly cludgy solution (in case no one ever finds a REAL solution to the problem).
I have a page variable defined as:
Dim eInsertArgs As FormViewInsertedEventArgs
And then I do the following in my ItemInserted handler
If boolInsertErrorOccurred = False Then
e.KeepInInsertMode = True
eInsertArgs = e
[Code].....
The effect of this is that I am setting the values BACK to the submitted values AFTER ASP.NET binds the FormView to the default (blank) Template.

I'm trying to find a way to have text that would be "Live" as in if a user types an incorrect phrase/letter in a text box, a message will appear prior to a "save" button being pressed. It's pretty much the same as when you're registering on these forums, it checks the availabilty of the username as you type it.

the project here is to take the three amounts from three text boxes entered by the user and return a string in a label telling the user if the triangle is either a right triangle, equilateral triangle, or neither after clicking a button. The code I have must use a new Class named Triangle. No matter what is entered in the text boxes, the label always returns "You created a right triangle!"

Windows forms Application. VB .NET 4.0 In my application I have a global boolean variable that keeps track of when changes are made and when they are saved called changesSaved. On closing even it checks the value of this variable before closing the window.. I am using textchanged event to automatically change the value of changesSaved to FALSE when text is changed.. Problem: The group box items are being populated dynamically so the user can edit the values or simply just view them. This dynamic population is causing the textchanged event to fire because the program is changing the text value of the box to put the values in that are stored in the database. The textchanged event should not fire unless the user him or herself enters a value or values in the text boxes..
Is there a way to specify the source i guess you could say for the text changed event or another way so that it will only fire when the user inputs information.??? Functions are as follows: The first is called by the load event to place the values in the box... The next one is the one that is being called as a result of the first one and is also the one that is causing the problems.

I'm trying to match a string to see if it matches exactly this:####-####, it has to be 4 digits followed by a hyphen followed by 4 more digits. Right now I have this pattern: "d{4}-d{4}" but it's allowing 5 digits in either (or both) instead of strictly 4 per group. Here's an example of what it should allow:
1999-2000
2003-2007
2009-2010
and here's what my pattern is allowing but should not be allowing:
20081-2009
2009-20101
12345-12345
12345-1234-1234
