PRB: Setup Toolkit File Copy Progress Gauge not Updated

• Microsoft Windows Software Development Kit (SDK) for Windows version 3.1
• Microsoft Win32 SDK, versions 3.1, 3.5, 3.51, and 4.0

SYMPTOMS

The following may be noticed during the execution of a setup program created with the Setup Toolkit:

1. The copy progress bar appears frozen even though the user may be prompted to change disks.

2. The filename shown at the top of the copy progress dialog box does not change for long periods of time.

CAUSE

The "gas gauge" copy progress dialog box (or Copy Gauge dialog box described on pages 106-107 of the "Setup Toolkit for Windows" manual) is updated only when files are actually being copied to the hard disk. The Setup Toolkit does not update the copy progress dialog box when it checks the version of an existing file. This version check can take a significant amount of time under certain circumstances. A version check is only performed if "Check For Version" is marked in the DSKLAYT program AND the file has a version information resource.

RESOLUTION

There is no way to change this behavior. The dialog box is managed by CopyFilesInCopyList(). The only way to avoid this behavior is to avoid marking files with "Check For Version" in DSKLAYT.

MORE INFORMATION

Under certain circumstances, a file may need to be copied to the temporary directory before its version can be checked. This occurs when the version information in the .INF file matches the version information (exactly) in the file already residing on the hard drive. In this case, the file will be copied from the Setup disks to a temporary location (decompressed if necessary), and other version information will be verified. This can be a time-consuming process and the copy progress dialog box will not be updated while this is occurring.
