Hi,
I've been playing with the new powerclient feature for deploying our applications and I'm really starting to like it!
When installing on our customers, we normally specify a command line argument in the shortcut to the app, to indicate which database has to be connected to. In the powerclient project, you can also set commandline arguments, separated by a "," if you have more than one. I've done a small test, which shows a messagebox with the value of the commandline and after deployment to the client the messagebox indeed shows the value correctly.
My question is though: Where is this value stored? The documentation states the following:
Commandline arguments
Specify the command line arguments for the application. The arguments must be separated by commas if there are more than one argument.
The arguments will be directly passed to the application when the application is run. And the arguments will be automatically saved and updated to the app startup icon on the desktop and the app shortcut menu in Windows start.
The arguments specified here will be passed before the arguments that are appended dynamically or manually to the application URL.
I cannot find the value anywhere, not in the shortcut, not in the registry. So if one of our employees / customers wants to change the database he's connecting to, we now need a developer to change the powerclient object (or have another one prepared) and re-deploy the project to the server. It would be easier to simply edit the shortcut. I've tried to add an argument to the shortcut itself, but that one is being ignored it seems.
Another thing I don't like too much, is the way to uninstall an application on the client. In the control panel (now "Apps and features"), the only program listed is the cloud installer. To uninstall an application, there's an uninstall shortcut next the the shortcut for the application. That does work, but normally we would remove the uninstall shortcuts, to avoid the users "accidentally" uninstalling the application. So then the only way to uninstall would be to go to %Appdata%\pbapps\applications\local......", not the easiest way of uninstalling for a novice user.
I've heard Armeen say that we are going to be able to change the installation path to something different then %appdata%, but for now (R3), I have not seen the option yet?
(I've also noticed that after the first install, windows sometimes prompts me with a dialog from "the store" saying something of having to download something, other times it doesn't).
Now that we have a lot more files (every objects is a file), I'm wondering if that could mean a 'slower' execution of the application. Also, the possibility of 'encrypting all the files', makes me ask the same question. (when I have some time I'll try to do some testing on that).
Just my initial thoughts,
regards
