Symantec Top 10

This monthly column, written by Symantec's Technical Support Engineers, is intended to give our readers technical information on using Symantec products.
Q: I am using SPM version 8.1 of the version 8, release 5 update CD, and I cannot launch the project manager. I have 110 MB RAM, and plenty of free disk space, so memory should not be an issue. I have removed the preference files, rebooted with minimal extensions, but the SPM still won't launch. Is there something else I should be doing, or something I have missed in order to get my project going?
A: Believe it or not, memory is exactly the issue! The Symantec Project Manager has a problem running on machines having 110 MB or more. However, there is a work around that will get you up and going.
Open the SPM in ResEdit or Resourcer. You are looking for STR#' resource 203 containing 3 strings. The last two strings are causing the problem.
2) <Factory Defaults>
3) <Factory Default Prefs>
Exit out of the resource editor, saving the resource changes. You should now be able to launch the project manager without difficulty and go merrily on your way with your project.
Q: I've downloaded the Preview Version of Visual Cafe, and I am experimenting with the product. One thing I have noticed is that I cannot just open a Cafe project and work on it in Visual Cafe. Is there a way in Visual Cafe to open a pre-existing Cafe project and work on it?
A: At this time you cannot open a pre-existing Cafe project through menu commands. However you can create a new, empty Visual Cafe project, and drag the .java and html files from your Cafe project to the empty Visual Cafe project. Make sure you set the project type correctly. That is, either applet or application, depending on which one you are opening. Alternatively, you can open the appropriate Visual Cafe project model, drag the existing files to the trash, then drag the files from the Cafe Project to the Visual Cafe project.
Q: After experimenting with Visual Cafe for awhile and having some successes and failures, I find the Visual Cafe Toolbar contains only one button. I tried throwing away the Visual Cafe Prefs file, but the problem persists. What can I do to get back my Toolbar?
A: You were part way there when you trashed the Visual Cafe Prefs file. There are two other files you must get rid of as well. In all, the three files are:
:System Folder:Preferences:Visual Cafe Prefs.
:Visual Cafe:Default Component Library.
:Visual Cafe:Component Registry.
On restarting Visual Cafe, the Toolbar should contain multiple objects.
Q: I think I found a bug in the Image Viewer... It will not recognize Macintosh style pathnames. It seems to recognize only Unix style forward slashes in the pathname.
A: Actually, that is not a bug. It is something specific to Java that we cannot change.
Q: I recently installed Cafe DR1 for the first time. Then I downloaded DR2 from the Symantec Web site. Now when I try to launch some of the sample projects, I get this error message:
Sorry, Java cannot run.
Could not initialize Threads.
Is the classes database present?
Is there something I need missing from the DR2 install?
A: Probably the safest thing to do is to throw away all your Cafe prefs and remove any trace of DR1 from your hard drive. Then, just to be sure, reinstall the DR2 product. Odds are that the original install did not go quite right.
Q: I am being plagued with the following error message:
Couldn't complete the last command because the volume was not found. Result code = -35
What is the problem with my project?
A: Select Options from the Project menu and set the application type to application, and also set main() as your application entry point. If you have an applet, add the html file to the project and set the application type to applet. Set the html file to your html file, not the default example.html.
Q: I am having problems uploading applets to my Internet service provider. My class files seem to get mangled, and it is very hard to determine if it is Netscape 3.0 Gold, Symantec, the ftp process, or my provider's Unzip that is doing the mangling. Is there a way to determine the nature and source of the mangling?
A: You must make sure that you are doing a binary upload. If you do a text upload, the end-of-line characters are changed to match the platform. Try a binary upload with Fetch if you do not find a way to specify binary with Netscape.
Q: I installed Cafe DR2 on my 68k Macintosh and it installed an extension called StdClib into the system folder. When I reboot, the extension is not loaded. What is this extension for, and will it cause a problem if it does not get loaded?
A: You can safely remove the StdClib from the system folder of a 68k Macintosh. It is a PowerPC extension and is not used on 68k machines.
Q: In C++ version 8.1, how do I get CTable to show only 3 columns regardless of the window size?
A: To make the table only show the same number of columns, override the Draw method and resize the columns based on the current width of the window. For example:
void CDerivedArray::Draw(Rect *areA:
// Get current frame of table pane
static int oldWidth=0;
// find width
// If width hasn't changed, don't do anything
// Update width
// Draw table
Q: I am trying to convert a Pascal record that has a data type of Byte into a C++ structure. I am using the C char as the equivalent of Byte, but I am getting some bizarre behavior and results. What am I missing?
A: The C and C++ equivalent to the Pascal Byte is the unsigned char.
My thanks to Scott Morison, Kevin Quah, and the rest of the support and QA gang.
