3x login error will terminate a program

Asked By Noah Baker 25 points N/A Posted on - 04/05/2012

I want to code a validation in VB6.0 login form. I want the program to terminate when the user entered a wrong username or password three times. In addition, the program will return an error message stating "You are not a valid user. The Program will be terminated" . All I need is a sample code for this. Thanks

3x login error will terminate a program

dim count as integer

private sub form_load()

count=0

end sub

private sub cmdlogin_click()

if <’txtusername’> < >  <’uname’> then        // If the username does not match the required username,

count = count + 1

msgbox(“Entered username & password is invalid”)

If count >= 3 then

unload me

end if

end sub

 

The program takes a global variable ‘count’. the form_load procedure initializes the global variable.

on unmatched usernames, the count variable increments and when it reaches a klimit the form is unloaded. A message box is displayed for entering wrong password.

Replace the txtusername.text  with the entered string and the uname with the list if usernames (one at a time). use a loop for the with the entered string and the uname with the list if usernames (one at a time). use a loop for the with the entered string and the uname with the list if usernames (one at a time). use a loop for the with the entered string and the uname with the list if usernames (one at a time). use a loop for the forloop  if you have many usernames.

Thanks.
