Creating CAB Files

Creating Device-Specific CAB Files
Required? Yes
236
The Windows CE operating system uses a .CAB file to install an applica-
tion on a Windows CE-based device. A .CAB file is composed of multiple
files that are compressed into one file. Compressing multiple files into one
file provides the following benefits:
S All application files are present.
S A partial installation is prevented.
S The application can be installed from several sources, such as a desktop
computer or a Web site.
Use the CAB Wizard application (CABWIZ.EXE) to generate a .CAB file
for your application.
Do the following to create a device-specific .CAB file for an application, in
the order provided:
1 Create an .INF file with Windows CE-specific modifications (page 236).
2 Optional Create a SETUP.DLL file to provide custom control of the
installation process (page 248).
3 Use the CAB Wizard to create the .CAB file, using the .INF file, the
optional SETUP.DLL file, and the device-specific application files as
parameters (page 249).
Creating an .INF File
An .INF file specifies information about an application for the CAB Wi-
zard. Below are the sections of an .INF file:
[Version]
This specifies the creator of the file, version, and other relevant informa-
tion.
S Signature: "signature_name"
Must be "$Windows NT$" as Windows CE is not available on Win-
dows 95.
S Provider:
"INF_creator"
The company name of the application, such as "Microsoft."
S CESignature:
"$Windows CE$"
EXAMPLE:
[Version]
Signature = "$Windows NT$"
Provider = "Microsoft"
CESignature = "$Windows CE$"
