Woah, this is too much unknown info for me there mate.
The change password class changes the password for the user logged in.
Are there any examples I can look at for what you are saying?

First up split the database connection and authentication of the application out from the authentication of the users.
Create a SQL standard login for you app. Now you application has na identity that it can use to connect to the database regardless of the user.
Create your own user table where you store all the data to authenticate you users (userid, password - encrypted, expiry date and any groups he user may belong to in your app, email, names, address, phones, etc etc)
You login form can now talk to your database (using it's own ID) and query the user table to check the userid and password, if the login is valid then pass the user to the main form.
I think there is an example login project here on CP if you search for it.

Thanks for the reply Mycroft.
The way you described it in your post sounds like what I am looking for, would you know the name of the project?
Thanks

Heres a little light reading[^] for you.
It is after all a fairly large and critical area of developing. try wandering through some of these articles and pick the ones most relevant to you.

Handle the form's closing event. FormClosingEventArgs has a CloseReason property. If it is CloseReason.WindowsShutDown , write log file.

Hello, in my windows form app, i have a function that acts as a loop. This function calls other functions and runs through the code.
Example:
Loop()
{
one();
two();
three();
four();
and so on
}
How can i create a 1 second wait time in between each function within Loop()?
There will be many function calls within this Loop() so setting a timer_tick to call a specific function wont work for the rest.
It cannot be Thread.sleep as this is a single thread app.
Thanks!

Hi,
Plaese try this
Loop()
{
one();
System.Threading.Thread.Sleep(1000);
two();
System.Threading.Thread.Sleep(1000);
three();
System.Threading.Thread.Sleep(1000);
four();
and so on
}

Hello
Sorry but you did not fully read my question.
Cannot use Thread.Sleep because it is a single thread app.
|
|
|
|
|
Why? Thread.Sleep works also with a single thread application: it blocks the current thread.
It looks to me that you are omitting some details that could be useful for us to help you, can you explain more what your problem is?
|
|
|
|
|
Ok, I thought people would understand that since it is a windows form application, that i would not want it to seize up with a Thread.sleep.
My mistake.
Thanks for the response.
|
|
|
|
|
Oh, ok.
Then you can not do what you want with a single thread: use a BackgroundWorker to run your function.
|
|
|
|
|
Will that work with an ActiveX com object? Because i tried to do A separate thread for the loop and the webbrowser control on my app broke.
|
|
|
|
|
I've used a BackgroundWorker in an ActiveX object written in C# and loaded in a WebBrowser control before, and it worked.
You have obviously to make sure to use Invoke when updating the UI in your separate threads, though.

Hi,
if you only want the one thread, you should use a Windows.Forms.Timer and put your stuff in its Tick handler. It would tick every second, and your code should be done in much less, otherwise you ruin the user experience and really need a second thread (as in a BackgroundWorker).

Well if i went the timer route, wouldn't i need a timer for each function? Ideally i want to use a timer, but i just cant figure a way on how to do it. There might be 10 or more function calls within my Loop function. Is there a more simple approach to using the timer?
Just to reiterate, my Loop function would look somthing like this:
Loop()
{
One();
Two();
Three()
...
up to 10 or more function calls.
}
The goal is to have about a 1 second wait inbetween each call
Ex:
Loop()
{
One();
Wait 1 second
Two();
...and so on
}
Thanks!

Hi,
you can't control time if you refuse to use threads, sleeps and timers.
IMO the easiest way is using a timer, and an counter, say (pseudo-code):
timertickHandler() {
switch(counter) {
case 0: One();
case 1: Two();
...
}
counter=(counter+1)%MAXCOUNT;
}
