VS 2005 How To Check If At Least 1 Phone # Is Entered
Dec 2, 2010
On my form I have 4 Phone Number fields, at least one of them has to have a number entered for contact purposes. I am trying to check and see if at least one is. I declared a form variable;'declare a variable to see if at least 1 phone number has been entered Dim count As Integer = 0..In the text changed event I do this;[code]But when I add a breakpoint as soon as I run the app it says count is 1 on the first phonenumber. What is the error in my logic. Somehow I need to be able to tab through all 4 controls and if they are all empty then let the user know they need to enter at least 1 phone number.

I want to validate a string in a textbox after a period.Lets say that it needs to be ".rad" (whatever). When I enter "radjesh.rad" and press "OK" it should check if the last 4/5/6 (whatever) characters (including period) are in the string. If I'd enter "radjesh" it should fail, but if I'd enter (e.g.) "radjesh.jrkrk" it should work.

I am thinking of dialling the number and if it rang then it is existing but I am not sure how to implement such. I am on Vista and it looks like all comm ports are not available or that I don't know how to enable them. Upon googling I have found samples of TAPI but I am unable to make them work, the following code is supposed to call a phone no. but I am getting the exception "Value does not fall within the expected range." on the 2nd line and I am clueless as to how to fix it

I have distributed a simple VB 2005 application that generally runs just fine without any installation: the user just inserts the CD and it starts via autorun.inf. The rare problem the users have is if they do not have .Net Framework 2 installed. I want to catch this error in my application, and display an appropriate message. I also want to test this on my own computer (which of course has the Framework installed). So my questions are
1. Should I be using a try-catch-end try in the form load sub, or somewhere else? and
2. How can I test this on my own computer without un-installing the Framwork? If I can raise an error while debugging, what error number should I raise?
