Suggestions required: how to customize the splash screen for arcpad project on initialization..
Here is a way to "turn it off"
I know I have mine turned off by default, and have all custom toolbars. First thing the user does is click on a button that calls the project setup form. I don;t know that I used anything mentioned above, but not 100% sure how I turned it off. Actually the software splash screen comes up for a bit. We are using v7.1, not 10.x...for what it's worth.
edit: you may want to look at ArcPad User Guide
You can create custom toolbars that work only within a specific applet or via the default configuration file so that they are always loaded when ArcPad starts. These new toolbars can contain a combination of built-in tools, that are found on ArcPad’s default toolbars, and user-defined commands, that call custom scripts. You can hide or display any of the built-in toolbars and specify that toolbars include large format buttons.
Toolbars are loaded into ArcPad as follows: on startup, ArcPad loads any custom toolbars from the default configuration file (ArcPad.apx). As each applet is loaded, its toolbars are then added to the system.
