Cannot write to a read-only file foxpro
Can that user create, close, open and modify a textfile at the same location as your dbfs? Visual FoxPro: It's magic! Not sure what you mean by a different network share, could you elaborate? It is on a network share, but I'm not sure what you mean by different. I will check on the modifying a text file as soon as I can get someone over there to try it.
I know what you are talking about with the select into cursor, but that's not happening here, the actual command to open the DBF is It must be a permissions problem, but all permissions appear to be correctly set. There is a readonly attribute on the folder that cannot be removed through windows. Supposedly it can be removed through a command prompt with the attrib command, but I tried that and it didn't work. A Microsoft knowledge base article mentions this, and says that it can sometimes prevent certain programs from writing to that folder, so perhaps that is part of the problem.
If you're interested, it is KB The same thing happens with a text file in that directory, the user cannot save it because it's read only, so it doesn't appear to be a Fox specific issue. I have the network administrator working on it, but we're both kind of stumped.
Am I right? Note, to David's point, you may be "Pointing" to a Foxuser. DBF on the server, in which case, it may also be the problem. Also, can you send the bit of code that is the "Offending" lines?

So an insulation layer is a good architectural idea that comes at the cost of slightly deeper hierarchies. Now, if you're following along, you see that we soon have all these classes in all these layers!
How best to deal with them? A class library is a physical package of classes. But classes can -- and should -- be abstracted in a variety of other ways. The Component Gallery is great for creating virtual and abstract groupings of related items in a way that personally suits a particular situation. Good Practice: Use Ken Levy's superclass tool; it lets you see exactly what your inheriting. The deeper your class hierarchies, the more you'll appreciate tools like SuperCls.
Supercls gives you the ability to see and edit superclass code while working in the class designer's code editing windows. To switch project mappings all you have to do is double click the file in explorer. Visual SourceSafe only lets one person check out a class library at the same time. Individual classes, be they stored in VCX or. PRG files, cannot be individually checked out. So checking out a class means checking out the library wherein the class lives.
Moreover the probability of finding that a particular library is not available for immediate exclusive use rises with the intensity of development, the number of concurrent developers, and with the number of classes in each library.
These forces imply that you should, as much as possible, shoot for small class libraries. It's a good idea to use class libraries to package things that should be packaged together. If this is so, then checking out a class library should give you exclusive access to things that are functionally related. So when designing class libraries, think cohesion instead of type. In this sense, unless you work alone or in a very small team, having a class library for "buttons" or "forms" makes little sense.
At first glance segmenting classes into libraries appears simple: Keep first-level subclasses in one VCXes, all forms together in one VCX, cool controls together in another, with other VCXes for, say, composite classes, forms, toolbars, and so on. Everything is straightforward and, if anything, things are easy to find.
But the guiding principle of class library segmentation is coupling. Physically arrange your classes so that distributing and reusing them is not hampered by external dependencies. Classes that depend on each other should probably be stored together, or proximately in related class libraries.
