Database names only in ASCII?
Hi, The documentation for DmCreateDatabase says that Database names must use only 7-bit ASCII characters (0x20 through 0x7E). Yet when I inspect the databases on my device using Filez, I see that several of them have accented characters (outside the ASCII range) in their name. I know that Palm OS uses the Windows-1252 character set(at least those sold in Europe and North America do). Is it really an error for an application to use characters outside the ASCII range for database names?

Re: Making my own IDE...
Tom Frauenhofer [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Another alternative - use the Eclipse IDE platform (downloadable from http://www.eclipse.org) and the C/C++ Development Toolkit plugin, tied into prc-tools. It's free and you can easily extend it to add editors for other things (for example, you can try one of the free PilRC tool builders if you don't want to edit the PilRC source directly, or you could buy Falch.net's PilRC Designer for $29 and tie it into the .prc files yourself...). You should even be able to tie in GDB debugging. Has anyone tried graphical debugging with prc-eclipse [1] and the GDB from PRC Tools 2.3? If so, how did it work? I don't want to upset my existing Falch.net/Cygwin installation by installing PRC Tools 2.3. I don't have testing machine to try it out either. I'm using Falch.net right for Palm development, but I would switch to Eclipse in an instant if only it had working graphical GDB debugging(my main reason for sticking with Falch.net). The GDB text interface is just too cumbersome.

Re: How to wrap lines for list items?
AFAIK, it's not possible to draw list items of variable height(which is what your question boils down to). You could implement your list as a gadget. This gives you the most flexibility in how items are displayed. Creating a gadget is more work, though, because you have to implement the drawing and event handling yourself.

Re: calling NETLIBSEND repeatedly
Arijit Das [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] I am calling NETLIBSEND repeatedly to send a string to the server. On the server side I only see the first string sent, other calls are not recieved at the server side. Any pointers as to how to call NETLIBSEND repeatedly. The fact that the calls are not received at the server side may be dependent on the protocol you are using. With HTTP/1.0, for instance, the server replies once it receives a blank line and then closes the connection. NetLibSend should have no problems sending multiple pieces of data. (I assume you know that NetLibSend has to be called in a loop, to ensure the buffer is sent in its entirety.) Provide more details if you're still stuck.

That means that, for instance, a button that is 30 pixels wide on an M130 will be 60 pixels wide on a Zire71. Use the Zire71 or another OS5 simulator to verify this.

C++ virtual functions
Hi,
Are there any hidden costs to using virtual functions in C++ classes using
the PRC tools? (I know about the GCC compiler and linker switches to disable
exceptions and RTTI.)
I know that polymorphism requires an in-memory table to ensure that the
correct functions get called at run-time (late binding) and that this eats
into the available heap size. However, I want to use pure virtual functions
in my classes solely to specify a contract that subclasses must abide to. I
will not use base class pointers, only pointers to non-abstract classes.
Example:
---
class BaseClass {
protected:
int a;
public:
virtual void add(int a) = 0; // Pure virtual function
};
class DerivedClass: public BaseClass {
public:
DerivedClass(int a) {
this-a = a;
}
void add(int a); // Implementation omitted
};
BaseClass* a = new DerivedClass(1);
a-add(1); // Polymorphism, late binding
DerivedClass* b = new DerivedClass(1);
b-add(1); // No polymorphism(?), early binding(?)
---
I have a gut feeling that the GCC compiler is smart enough to resolve the
function call for b at compile-time, hence no need for a function table at
run-time, but I'm not sure. (It's been years since I last used C/C++ for a
large project.)
Also, how much memory does polymorphism actually require? Should you really
avoid it at all costs on Palm OS? My target is OS 3.5+ running on 4Mb+
devices.
Thanks
-Laurens
