TestStand - Start Modal Dialog

Owning Palette: TestStand

Makes the calling dialog box VI modal to the TestStand main application window. When you call this VI, you must then use the TestStand - End Modal Dialog VI to make the dialog box non-modal to the TestStand main application window before you attempt to interact with the TestStand main application window. The call is the first thing the calling VI must do in order for TestStand to properly set the modality of the dialog. If you do not call the TestStand - End Modal Dialog VI after you call the TestStand - Start Modal Dialog VI, the calling dialog box remains modal and you cannot use the TestStand main application window. You must manually select the polymorphic instance you want to use.
Note If a TestStand SequenceContext object and a TestStand Engine object are available, National Instruments recommends that you select the SequenceContext instance to ensure that only one thread at a time displays a modal dialog box.

Sequence Context

Sequence Context In specifies an ActiveX reference to a TestStand SequenceContext object.
VI to make Modal (Current VI) A reference to the VI you want to make modal. If you do not specify this parameter, the VI that calls the Start Modal Dialog VI is made modal.
error in (no error) describes error conditions that occur before this node runs. This input provides standard error in functionality.
Sequence Context Out returns the Sequence Context In parameter unchanged.
Modal ID returns the ID you pass to the TestStand - End Modal Dialog VI.
VI Originally Open returns TRUE if the front panel of the calling VI was open before it called the TestStand - Start Modal Dialog VI. Pass this value to the TestStand - End Modal Dialog VI.
Should Abort returns TRUE if the user terminated or aborted the calling execution while this VI was running.
error out contains error information. This output provides standard error out functionality.

Engine

Engine in specifies an ActiveX reference to a TestStand Engine object.
VI to make Modal (Current VI) A reference to the VI you want to make modal. If you do not specify this parameter, the VI that calls the Start Modal Dialog VI is made modal.
error in (no error) describes error conditions that occur before this node runs. This input provides standard error in functionality.
Engine out returns the Engine in parameter unchanged.
Modal ID returns the ID you pass to the TestStand - End Modal Dialog VI.
VI Originally Open returns TRUE if the front panel of the calling VI was open before it called the TestStand - Start Modal Dialog VI. Pass this value to the TestStand - End Modal Dialog VI.
Should Abort returns TRUE if the user terminated or aborted the calling execution while this VI was running.
error out contains error information. This output provides standard error out functionality.
