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.
Change:
2)
To:
2)
Change:
3)
To:
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
GetFrame(&r);
static int oldWidth=0;
// find width
int width=r.right-r.left;
// If width hasn't changed, don't do anything
if(width!=oldWidth)
int numCol=GetColCount();
for(int x=0;x
SetColWidth(x,width/numCol);
}
// Update width
oldWidth=width;
}
// Draw table
inherited::Draw(areA:;
}
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.
