Creating self updating applications with the net compact framework
Many devices, including the CE Emulator, come with version 1.0 of the Compact Framework installed. Label; procedure Initialize Component; procedure Button1_Click(sender: System. Event Args); procedure Button2_Click(sender: System. You can check the version on your device by opening the . If you do not have Active Sync then you will need to download the developer version of the CF Framework. Unpack it, copy the appropriate CAB file to your device and open it from there to install it. NET Framework, some properties specific only to that were generated in our section. NET Framework SDK documentation explicitly states which methods and classes are available on the Compact Framework, so dilligent referral to this is recommended, especially considering not all instances will be picked up at compile time. Dispose(); end; inherited Dispose(Disposing); end; constructor TMain Form. Our Hello World application can be unloaded from memory by accessing the Memory section of the Pocket PC system settings, but for simplicity now we will simply shutdown and restart the emulator. Restart the emulator, and our application can once again be compiled to the Storage Card directory. We will change the code to fix these errors and attempt to compile the application again. Label; procedure Initialize Component; procedure Button1_Click(sender: System. Create; begin inherited Create; Initialize Component; end; procedure TMain Form. We will now also change our code to add a Close button, so the application can be terminated normally. Once you have the emulator installed, make a copy of the menu shortcut and modify it. Below is an example of a valid command line for the emulator.: Additional emulator images can be downloaded from the Microsoft website, and the CE 5.0 emulator can be configured to use these so other devices can be emulated. For this article, we will create an application that targets Pocket PC devices running the Windows Mobile 2003 operating system.
If you have a slow connection and do not yet have MSXML 4.0 sp 2, installed it also helps to download and install this first. As the preview compiler can not be invoked directly from the Delphi 2005 IDE, we will set up a batch file to assist us in compiling Compact Framework applications. Create; begin inherited Create; Initialize Component; end; procedure TMain Form. Also thanks to Marc and John Kaster for assisting with some of the technical aspects of this article.The batch file we will use looks like this:- @echo off rem ************************************************************** rem ** Batch file to be used from the Delphi 2005 IDE Tools menu rem ** to invoke the Compact Framework Preview compiler. And of course, thanks to Seppy Bloom, Danny Thorpe, Tagawa-san, and all the other R & D engineers who made this article possible in the first place by creating the preview compiler.The first step is to download the preview compiler from the Registered User Updates page, and to install it onto your development system. This article has hopefully provided some guidance to allow developers to start exploring what will be for many a new and exciting world.For this article, the compiler and all support files have been extracted to the 'C:\Program Files\Borland.0\CF Preview' directory. Dispose(); end; inherited Dispose(Disposing); end; constructor TMain Form. Thanks to Marc Rohloff for the permission to use excerpts from his Getting Started with C# and the Compact Framework article.
