PRB: Problems with ODBC Setup PPC Control Panel (167404)


The information in this article applies to:

  • Microsoft Visual FoxPro for Macintosh 3.0b
  • Microsoft Data Access Components 2.5
This article was previously published under Q167404

SYMPTOMS

When opening the ODBC Setup PPC control panel, the following error message is received (usually endlessly):
An unexpected error occurred, because an error of type -192 occurred.
Or after setting up a data source in the control panel, one or more of the following symptoms are present:

  • The Shutdown command on the Special menu in Finder is missing.
  • The Shutdown command on the Special menu in Finder is a long string of garbled text (high ASCII characters, hollow boxes, and so forth).
  • A message about there not being enough memory to keep open the window for the hard drive, even though no other applications are running.
  • The above message except part or all of it is the garbled text.
  • The problem clears up if the Macintosh is restarted.

CAUSE

This is known to happen on PCI Power Macintoshes running System 7.5.5 when running a PowerPC-enabled application. These applications seem to cause Finder to hold onto additional memory creating an out-of-memory situation.

RESOLUTION

This has reportedly been fixed in System 7.6. In addition, the problem has not been reported with System 7.5.3.

The following steps can also be used to correct the problem. They increase Finder's heap size. These steps involve the use of the ResEdit resource editor available from Apple Computer. Editing resources is for advanced Macintosh users only. Microsoft does not directly support this. This information is provided only as a convenience to our customers.

  1. Make a copy of Finder. The easiest way is to hold down the Option key while dragging it out of the System folder to another folder of your choice.
  2. Start the ResEdit program.
  3. Open the copy of the Finder that was made in Step 1 above.
  4. Double-click the SIZE resource. A window titled "SIZEs from Finder" should appear.
  5. Double-click the -1 ID. A window titled "SIZE ID = -1 from Finder" should appear. Scroll to the bottom of it.
  6. Change both the Size and Min size settings to 239440. This should be an increase of 50000 for each.
  7. Close the two windows and save the change to Finder. Then quit ResEdit.
  8. Rename the Finder in the current System folder and then move in the new copy of Finder that was just changed in ResEdit.
  9. Restart the Macintosh and delete the old renamed Finder.
