pop-up window

[JFMoynihan]

I am working on a program that frequently writes and reads from a database. When I am writing or reading waveform information to the database, the processing time is long. I would like to display an pop-up dialog box that tells the user what is happening (i.e. "Writing waveform data", "Retreiving waveform data"). I would like this box to pop up when the process starts and disappear when the process is finished, without any user interventions. I have made some dialog boxes to display the comments listed above, but I can't get the boxes to pop up and close when I want them to. I would appreciate any help.

Thanks.

hi JFM,

The easiest way would be to call pop VI using VIServer during different times of your main VI (the one which is writing/reading data from the database).

You can excute FrontPanel.Open property with bolean TRUE and FALSE at different times thereby controlling the pop up window to appear and disappear.

A simple way that I use is to make the sub-vi that is doing the processing pop-up with the message while it is doing the work with the "show when called/close after" window option. Quick and dirty but effective.

Agree! Thats what i thought the first place but then i though he might just want to have one pop up VI called using VI Server with messages (string text) changing on the fly.

Hi,

Try this: put you writing- and reading-prozesses in a sub-vi. Set
preferences: frontpanel shown when sub-vi is called and closed if
finished.

Greetings Niko
