The [Platforms] section lists the complete set of platforms supported by this form. Each platform entry consists of the prefix Platform.string, where string is an arbitrary string code for the platform. Each string corresponds to the CPU entry of an individual [Platforms] sections. Each entry in a [Platforms] section defines a platform string that references a subsequent [Platform.platform string] section as shown here.
[Platforms]
Platform.string = platform string
Following is an example of a [Platforms] section.
[Platforms]
Platform.1 = NTx86
Platform.2 = Win95
Each [Platform.platform string] section contains the two required entries, CPU and OSVersion. The CPU entry specifies the processor, and the OSVersion entry specifies the operating system. Valid CPU values are described in the following table.
| CPU Entry | Processor |
|---|---|
| Ix86 | Intel 80x86 and Pentium series processors, as well as equivalent processors from AMD, Cyrix, NextGen and other manufacturers. |
| MIPS | MIPS R4000 series processors. |
| AXP | Digital Equipment Corporation Alpha AXP processor. |
| PPC | Motorola Power PC series processors. |
| M68 | Mororola 68x00 series processors. |
Valid OSVersion values are described in the following table.
| OSVersion Entry | Operating System |
|---|---|
| Win3.1 | Windows 3.1 and Windows for Workgroups 3.11. |
| WinNT3.5 | Windows NT 3.5 or lower. |
| Win95 | Windows 95. |
| WinNT4.0 | Windows NT 4.0. |
| Mac7 | Macintosh System 7. |
Additionally, the [Platform.platform string] section must contain either a File or LinkTo entry. The File entry lists the form server application executable file that the form library maintains and loads into a new subdirectory in the disk cache when the form is launched. If a LinkTo entry is used instead, it contains the name of a different platform string from which the File information is taken. This is useful if one version of a form supports multiple platforms.
The Registry entry is used whenever the File entry is used, it identifies the registry key for the form library where the executable file for the form server application is stored. Strings preceded by a backslash ( \ ) are placed at the root of the registry. Strings not preceded by a backslash are placed in the HKEY_CLASSES_ROOT\CLSID\GUID\ registry key, where GUID is the GUID of the form. The characters "%d" can be used to indicate the pathname of the directory from which the form configuration file has been read. This is useful for specifying other files with pathnames relative to the form configuration file. Multiple File or Registry entries can be specified by using File or Registry as a prefix followed by any other text. The format for the [Platform.platform string] section is:
[Platform.platform string]
CPU = string
OSVersion = string
File = path
LinkTo = string
Registry = string
The following are two example [Platform.platform string] sections, one using the File entry and one using the LinkTo entry.
[Platform.NTx86]
CPU = ix86
OSVersion = WinNT3.5
File = \helpdesk.exe
Registry = Local Server = %d\helpdesk.exe
[Platform.Win95]
CPU = ix86
OSVersion = Win95
LinkTo = NTx86
The [Platform.platform string] section is ignored when adding a form to the local form library, when it is assumed that the installer has placed the files constituting the message class handler into accessible local storage as named in the handler's section in the OLE registry, and has done the OLE registration in the system's registry.
