Hi all, I modified asbo's solution after reading about the Invoke node and its methods from Lesson2-LabVIEW IntermediateII I think I reached what I need, tested it, and I see that it worked Check the file is in the attachments Thank you all (dannyt, hooovahh, asbo)

QUOTE (asbo @ Jun 2 2009, 02:12 AM) That's great But I want the hidden VI to be closed I tried to test some methods such as Abort VI, Run VI but the didn't work as I expected and I think that I need some help about that because I found no details about Invoke Node methods in the LabVIEW help Do you have any document about the Invoke Node and its methods ? Thank you QUOTE (dannyt @ Jun 2 2009, 11:29 AM) I managed to open your original rar file and you just have two VI's a main Vi and a login VI. So are you really aiming for something as simple as :- run main.vi and when a button is pressed on that VI, you wish the login.vi to pop up allow a user to login and then for the login VI to disappear ? Dannyt Hi Dannyt I'm aiming for that In my project The buttons Go to main VI and Back to login VI are buttons that I want them to function as Sign in and Sign out Run the login.vi When user logs in using his account (This is done in my project using voiceprint but here I'm using the button Go to main VI for simplicity),I need to close (Not hide) login.vi and run (Not show) the main.vi When user finishes his work with main.vi, he signs out using the button Back to login VI and then, I need to close main.vi and run login.vi again This is what I need, sorry for any mismatch

hooovahh Thank you This is exactly what I need but the solution is very complicated. Is there another simpler solution ?

QUOTE (dannyt @ Jun 1 2009, 12:54 PM) dannyt, Thank you for your interest this is what i need to do I have 2 VI files each of them has a button switch when you are in VI#1 and press the button VI#1 is closed VI#2 is opened when you are in VI#2 and press the button VI#2 is closed VI#1 is opened This is what I meant by switching between two VIs

I have a simple problem How to switch between two VIs inside a project in LabVIEW 8.5 ? Here is a rared file to illustrate what i need , sorry i couldn't attach it simple project
