Display dialog based on boolean

[Giridhar_Rajan]

Hi all,

I have a SubVI. I want to display its front panel as a dialog box when a boolean goes high and it should vanish when the boolean goes low. Please help me out with this.

This Boolean, do you want it on the main/ calling VI or on the sub vi itself??

Devchander,

Boolean should be on the main VI

Hi Giridhar,

By "Dialog display", do you mean a message box without a button (ex: "OK")?   And "displayed on the sub-vi Front Panel", do you mean that when the sub-vi is called, you see the Front Panel and if the boolean is true, display the message if false, do not display... Is this what you are trying to do?

If so:  

you can right-click the sub-vi and select "Sub-vi Setup Node", then select "show front panel when called" and also place a checkmark "close afterwards if originally closed".  As for the message display, you can use a "Select" from "Comparison " in the Functions Palette.  Wire the test to display if True and wire an empty string if False.

Giridhar,

Did you get your question answered?  I'm not quite sure what you meant by "dialog box".  If you just want to programmatically show the front panel you can use VI Server in combination with an event structure to programmatically open and close the front panel of the subVI when the boolean control is toggled.

Giridhar,

Look at attached vi

Hope it helps

Devchander,

Thank for the VI. You are pretty close to what I want. I want the boolean switch on your main VI to be "switch when pressed", such that if I press it and leave, it should remain ON. While its ON, the dialog should popup the way it pops up right now. No stop button is needed in the dialog. If I press the boolean on your main VI again, the boolean will go off and the dialog should vanish. Thank again.
