How can pass data to a version of exe with LabVIEW?
I have an application that allows to launch one or more instances of the same executable using "system Exec' VI, false option" wait until the end? My problem is I want to transmit a different value for each instance, to an input parameter. Something like that if you launch notpad.exe, followed by a file name. The executable file is a generation of LabVIEW application too.
How can I do this?
Best regards
Passing parameters to the command line in a LabVIEW application is actually quite simple.
There are 2 things you need to do:
-Change the specification to build exe of LabVIEW to move all command line arguments to the application
-Read the property App.Args that returns an array of strings for the parameters - the first parameter is always LabVIEW.exe.
For an example:
Here, I've read the arguments ignore the LabVIEW.exe and then read a path as the first argument and the check, it exists and there is also an option '-choose ' parameter that determines whether to show the user interface.

How can I data IPTC save when you export with Fireworks

> How to store IPTC data when editing in fireworks?You are not supposed to be able to export. However, there is a bug
in CS3, if you SAVE the file first, metadata are stored on
Export.Keep in mind, this will increase the file size.

I don't like version 7. How can I go back to version 6?
I don't like version 7. How can I go back to version 6?
Downgrade to Firefox 3.6 first of all uninstall Firefox 4, but do not select the option 'remove my Firefox personal data '. If you select this option, it will delete your bookmarks, passwords and other user data.
Then you can install the latest version of Firefox 3.6 available to http://www.mozilla.com/en-US/firefox/all-older.html - it will automatically use your favorite courses, passwords etc.
I recommend, to avoid possible problems with decommissioning, accessing your profile folder and delete the following files if they exist - extensions.cache, extensions.rdf, extensions.ini, extensions.sqlite and localstore.rdf. Delete these files will force Firefox to rebuild the list of installed extensions, check their compatibility and cancel the toolbar customizations.
For more information on how to find your profile folder, see https://support.mozilla.com/kb/Profiles

How can I get an older version of Pages where I can format pages face to face
How can I get an older version of Pages where I can format pages face to face?
If you have an older computer, the old version of the pages is still in the folder of iWorks if I'm not mistaken, otherwise, if you still have the iWork DVD you can reinstall it after you remove the crappy version of Pages.
Otherwise... Maybe you can always buy some old DVD of it on the internet, don't know where you should look...
