I have a mask of : 00/00/0000

How can I check whether the user has entered a value to the maskedTextBox or not?
I have a masked text box for postal codes. When the user clicks the text box it sets the cursor to where ever they clicked in the text box. Is there anyway that if the value is empty it sets the focus to the beginning.
Private Sub Cust_postalTextBox_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Cust_postalTextBox.Click

Is the code I have that works but What would the IF statement be to check if it is empty? String.empty and "" don't work because I think it sees the mask as characters.
I have an insert statement which works fine but before the record is saved I want to validate the text boxes. So I just need to know how to check for empty text boxes before the save button is clicked on. I have seen a couple of examples like:
Dim ctr As TextBox
If ctr.Text = vbNullString Then
MsgBox("empty box")

View 1 RepliesBasically I am doing a weekly assignment for unit 7 where I have to use Data bases.... I have everything going fine I used VB studio to set up most of my relationships between the Data base and VB.I have a text box called txtLast4OfSSN.Text that I need to get the last 4 of a social security number.
Now this should be simple I have another box ( a Masked Box for SSN) that has the SSN in it... This box is called m_SSN.Text....... Now I figured it would be easy, and that I could just use the Substring(7, 10) to get those numbers :*( However its not working and I am getting an error as follows:"Index and length must refer to a location within the string. Parameter name: length".Here is my complete code with my two buttons its mostly in the second event procedure that I have the code specifically for getting the last 4 of the SSN:

I am using a masked text box to format phone numbers. However, I do not want the extra formatting that gets insterted from the masked text box: (800)-555-1212
All I want is: 8005551212
But I still want the user to type it in like this (to make it easier for user):
(800)-555-1212
I am thinking I can run a replace function on it, but I am not sure what event to use. I found a number of tutorials, but not that useful for what I am doing. [URL]

I have a process which grabs the birthdate and from a data table and display them in a masked text box for viewing and editing However when pushing the data into the textbox any preceding zeros get removed For example 05/05/2005 would display as 55/20/05__

View 10 RepliesI have a phone (and Zip Code) masked text box on a form. I am reading data from a SQL table. If I use the code at bottom in a lost focus call no errors are thrown but I see nothing in either masked text box. However, I tried a few things to understand whats happening. I inserted a standard text box on the form and sent the Zip Code value to it and it appeared in the box no problem. Also, if I use the following code: Zip_TextBox.Text = 01940 or Zip_TextBox.Text = "12345" in the form load it appears in the masked text box just fine. So I am not sure whats going on.
The code below is in the lose focus method for a combo box on the form. It all works correctly except for the Zip and the phone numbers fields which even though I called them text boxes they are masked text boxes.
