GDI+ (Optional)

Certain features of the control require GDI+ support. This is available automatically on Windows XP and newer Windows versions. GDI+ is available as a redistributable for Windows 2000, Windows 98, and Windows Me from Microsoft (www.microsoft.com) as part of the Platform SDK (Windows XP and newer). Usually, it is sufficient to simply distribute the Dll gdiplus.dll in your application directory.

When using SFTPRINTPREVIEW_DRAWINFO, pGraphics to render output to a page, GDI+ support is required.

Target Directory

The DLLs can be installed in the application's directory and can be used locally, without interfering with any other applications which may use other versions of SftPrintPreview/DLL.

The DLLs included with SftPrintPreview/DLL can also be installed in the Windows SYSTEM directory. Under Windows 2000, XP, Server 2003, Vista, Server 2008, Windows 7 and Windows 7 Server the 32-bit DLLs are installed in the SYSTEM32 directory. Under 64-bit Windows versions, 64-bit DLLs are installed in the SYSTEM32 directory and the 32-bit DLLs are installed in the SYSWOW64 directory. When installing DLLs in Windows directories, strict version checking and reference counting must be performed to avoid conflicts if different software packages use SftPrintPreview/DLL.

Any resource-only DLLs for National Language Support must be installed in the application directory (never in the Windows System(32) directory).

Version Checking

The DLLs included with SftPrintPreview/DLL carry proper version information. A shared DLL should only be replaced if its version information indicates that the existing DLL is older.

Commercial installers and setup programs have built-in features to insure proper DLL versioning. See your installer's documentation for more information.

Reference Counting

If a DLL is installed into the Windows System(32) or SysWOW64 directory directory, it can potentially be installed and used by other applications also. It is required that any DLL installed in such a shared location keep proper reference counts by updating the proper Windows registry keys:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SharedDLLs

Commercial installers and setup programs have built-in features to insure proper usage and reference counting. See your installer's documentation for more information.
