I have been trying to get the length of MaskedTextBox and then have the code perform a function.
Just so I am clear, I know I can use the MaskedTextBox.Full or the MaskedTextBox.Completed.
However, I would really just love to get the length instead.
Example:
If MaskedTextBox1.Text.Length = 5 Or _
MaskedTextBox1.Text.Length = 10 Then
[Code]...
I have 1 masked textbox. I made a custom mask. My custom mask is >AAAA - AAAA - AAAA - AAAA - AAAA
Now my problem is. When the Masked textbox is empty is showes this:
____ - ____ - ____ - ____ - ____
I do not want the underlines and the hyphens showing. I was able to remove the underline by changing the PromptChar to a space. Now my problem is the hyphen. I do not want them showing. But I don't want them gone. I want them to show when the user has typed in 4 characters in each space.
tell me the code for calculation in masked TextBoxes, I have 3 MaskedTextboxes Masked as Currency (C2)
MaskedTextBox1 Is reading off a table
MaskedTextBox2 I want to x by 1.5, the result of MaskedTextBox1
MaskedTextBox3 I want to x by 2, the result of MaskedTextBox1
this is not working?

1)This is my code.. (below)what i am trying to do here is to insert username and confirmed password into a sql table called login via a pre created form.I have 1 textbox, 2 Maskedtextboxes and a button.
what i would like is if the passwords do not match in both maskedtextboxes for the system to throw out a message saying passwords do not match please try again..which then clears previous content and requires the user to enter details again. once details are correct and system commits the new user details to the table and throws up a confirmation message.

I have a field displaying on a datagrid that the user has asked to be variable length based on the data that is returned. Is there an easy way to determine how many characters are returned for a field and then converting that to a pixel length so that I can change the length of the field in the code.

If using the following in an if statement I get an error: If trg.Name.Substring(4, 6).ToUpper <> ("ABCDEF") Then I get the error: "Index and length must refer to a location within the string. Parameter name: length"
I assume this is because the string (trg.name) is too small for the 4, 6 substring. What would be the correct method of working around this problem? VB.net Studio 2008.
