gif upload

Hello,

How to upload a .gif file  from system directory on a front panel by a button click.

Hi Venka,

use a graphics converter of your own choice to convert that GIF to PNG.

After having done so you use the standard PNG read function and display the image in a 2D picture indicator…

Does the gif have to move? If so you could use the .Net pictureBox.

MSDN Picturebox

Converting a gif file format gives many number of png files which cant be displayed at a time on labview.Im attaching gif file which I want to display on front panel.

[Venkateshnenavath]

Yes it have to move.

So, after playing around with the picturebox myself a bit, I'm gonna suggest just dragging the Picture on the Front panel and making it Visible/Invisible whenever needed using property nodes. Don't know what that does to the performance of your VI, though.

Edit: To expand on this a bit more: The way you usually see things like that done in the LabVIEW examples is by inserting all the pictures into a pict ring and changing through it programmatically. But that isn't really an option if you get hundreds of images.

Another workaround - use a Web Browser control and load the gif into that.

Works with the animation too.

Thanks for the solution.But after the first run of the program,it still shows the animation.I mean it always shows the animation no matter what we do(close and reopen the front panel).Can we do something to avoid it?

Try navigating to "about:blank" as the url to empty/blank the display. Or you could try the 'go home' method.
