This is my problem.I have a field set up in MS Access to Boolean YES/NO, this field is populated when the user check a checkbox on a windows form. If the user check a checkbox, the value is written as checked in the data field (MS Access).The problem is when I search for the user information, I need the information from the Data base to populate(return) to the windows form. Example: If I enter a users phone number and the user data is present, the form gets populated with the information the user previously entered which was store in the database.Example: If the user selected checkbox1 and submits the form. When I search for the user info, the check box should check(populate) because the user had checked it on submit.Here is what I have done:

View 1 RepliesI'm struggling with my computing coursework in college and I though My issue is simple but I can't get it right. I need to validate the text into a textbox and check that it contains ONLY alphanumeric characters, but it MUST contain both, not either numeric or alphabetic, but some of each.The textbox should store information about a Street address, that's why both the street Name and the property Number have to be input. Spaces " " and points "." should also be allowed.If it helps, something like "12" or "St. Davis Street" should NOT pass the validation checks, whereas "St. Davis Street 12" will do.I would like to get it done with regular expression as I've been using them throughout my work, but I don't mind other solutions.I'm using Visual Studio 2010 Professional, 4.0 framework and Visual Basic.
View 2 RepliesI am trying to figure out how to read a text file and check the value entered into a textbox to see if it already exists. Its basically a validation list.
I found some code on how to read a text file, but I do not know what to do with the information.
Sub Main()
If RadioButton1.Focus = True Then
'Check TextBox1 value against list of known part numbers

How do I compare the textbox value to a line read from the file and stop if there is a match?

I can identify the error.But I don't know.
Using .Net, I need to generate a response based on only the checkboxes on my form that have had there states changed. So how do I know if the check box has changed from its previous value before submission. I can't use the onchange event because the user may check multiple boxes before submitting.
