Datagrid New Row Cell Validation - Validate Empty Text And Indicate Error On Cell?
Jun 1, 2010The problem is that if you never enter anything into a cell for a new row then that cell is never validated. This is a problem because I have columns that should not be null. I am doing the check in the row level validation and storing the information about which cells are empty that should not be empty. The row level validation works fine and the row level validation error indicator goes on,(red exclamation mark at the beginning of the row) but I also need a visual indicator on the individual cells that are in error.
I am thinking that setting the HasError property for the cells that are in error should cause them to display n error style (the default red border). Is there a way to this this either from XAML (perferably) or from code?Alternatively I could cause those cells to re-validate when the row editing is finished. Does anyone know how to do this?

View 32 RepliesArray Is Empty - How To Validate
May 30, 2012I'm working on a program to delete files from a certain folder after they have aged a certain amount of time and either match via regex or extension. I'm running into an issue where files() could be:
files(0) = Nothing
files(1) = Nothing
files(2) = Nothing
etc....
Right now the way it is written, I could place
Else
log(1) = data(1)
log(3) = "Array field empty"
InsertLog(log)
And the program would log as many files as file(i) = Nothing holds. This would create redundant database records and is not wanted. Is there a way to figure out if ALL files(i) = Nothing and then place code in there to insert into the database?
'If log(3) is successful that means no files were old enough or deleted successfully
If log(3) = "Success" And IsArray(files) Then
For Each file In files
If Not file.IsNullOrEmpty(file) Then
'If files is actually something insert into the log
log(1) = file

View 1 RepliesForms :: Validate Textbox Empty?
Mar 1, 2011I started editing an existing code (basicaly to learn vb) without any real previous experience. Well let's get to the point;I have a form that gathers data from db ordering by user ID (on click count).I have one DataGridView with a list of user,some have data in db, some have not. I came so far that if I CLICK on a user that have data, all data is dissplayed in 6 dinamyc textboxes.If user has no data inly first (emty) row with 6 dinamyc textboxes is created.
BUT THE POINT IS (my question to you) - I have a button that simultaneously adds a row of dinamyc textboxes bellow and multiplyies textbox04 (name is clickcount & 4) and textbox05 and displays the result in textbox06.I want to add a messagebox that shows if textbox04 & 05 are empty and in that case exits sub. Here is my code so far:
Private Sub Button1_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Validate A Form With Multiple Text-boxes?
Dec 1, 2010The form has First Name, Last Name, Course and Email text box fields. First/Last Name must have no spaces, Course must consist of a three letters and two numbers in that order and nothing else(I want to avoid the use of masked text box), and Email must have the "@" sign and a dot. How would one make it so after clicking, say, Submit button and if there was a violation of any of the above rules then message box should pop up and tell the user which fields contain incorrect information.
Private Sub buttonAddNewStudent_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles buttonAddNewStudent.Click
'validation must be performed before the corresponding text box items will be placed inside an array

Change Text In Label.text With A Click Of A Button?
Jan 20, 2010I have this problem but I already simplify the code as below:Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Label1.Text = "hello"
System.Threading.Thread.Sleep(5000)
'MessageBox.Show("hahahaha")
Label1.Text = "world"
End Sub
What I'm trying to achieve here is, after I click the button, the label1.text should change to hello, and after that to world. But I couldn't achieve that. Instead when I click the button, it just paused for 5 second and displayed world.System.Threading.Thread.Sleep(5000) The code is just a dummy for a loop that I have.

View 5 RepliesDuplicate Form By Button Click?
Aug 24, 2010I want to create an application which can reset itself quickly and easily (without a function to do so). I thought one way to do this is to duplicate the form in it's original form (variables, etc) from the point it first loaded.This is how I thought it could be done:
1. Click button to restart application.
2. Form in use is duplicated by creating a new form with Dim newForm as new Form.
3. New form contains all properties of the original form at the time it was first created.
4. Original form is removed, and new form is used; thereby 'restarting' the application.
I can't find any simple way to do this without making a function which completely resets every variable and object (there's a fair number of them).
