RE: Files and full screen graphics
Hi, 1) How can i read/wrtie files? If you need files support in your application you might use file stream functions like FileOpen, FileRead. Have you read PalmOsCompanion.pdf file? There is whole chapter about databases and files. 2) How can i switch into between full screen mode? What do you mean by full screen mode ? Are asking about Hight-Density Display? If so, check WinSetCoordinateSystem() function and other windows function. 3) Where can i find some simple tutorial? Some examples comes with PalmOs SDK. I also advice you to check PalmOsCompanion.pdf, PalmOsCompanion2.pdf and PalmOsReference.pdf .

RE: files
Ok. Many thanks.
It works fine except that I lose 300 bytes.
Is there more data I need to read and send after or before sending
resources?

'appl' databases are Resource databases, so you can't use
DmQueryRecord. you should use
DmGetResourceIndex.
You can know if it is a ResDB by calling, DmOpenDatabaseInfo .

Re: Files on Palm
1. yes. for store other than secondary storage, palm usually convert them into db. However, you can also use stream but hotsync wont recognize this kind of files. 2. for my self, term file means raw file (as it is) and it fit within secondary storage. 3. basically, palm doesnt provide any file explorer (as windows desktop). However, you can find some good code from palm reference/companion. peter --- Ritu Chawla [EMAIL PROTECTED] wrote: Can some body help in answering my queries related to file streaming on palm device. 1.

RE: Files on Palm
Yes, u can store files on RAM of Palm device. It all depends on your requirements whether to use files or not! But as far as my knowledge is concerned there is no harm in using and storing files on Palm device as far as they are not too large. I don't know how to get list of files programatically but I use an application called FilePoint which is sort of file explorer for Palm OS.

Re: Files
Thx Ben, I'll look at that - sounds like a possible winner. The only thing I don't like about it is that I then need an installer to keep the loose files together. If I can't get on with your suggestion for whatever reason, is there a way that once I have a humungous chunk of binary (all the data files stuck together) and a header for it, that I can make CW munge it into the exe at a place where I can get a start address back from easily ? Assuming a yes, are their any gotchas in just returning a pointer to where the data is relative to the start, or do I have to allocate some fresh ram and copy it to a more local area ?

Here goes... I have some data on the desktop I need to move to the handheld. So I have to create a .PDB file, right? How do I do this - where is the format described? I guess some information is needed to associate the file with my app on the Palm? There are several answers to your question. You don't necessarily have to create the PDB yourself, in fact it's often the toughest way to go. There are some excellent tools for moving data from PC apps into PDBs; which is best depends on your requirements. A quick web search should turn up a half dozen or so. Some are stand-alone programs, but there are several OCX's that will allow pdb creation from within your app. Palm generally suggest that you use a conduit. We don't so I can't comment, but in theory it's the superior way for your PC app to exchange data with your Palm app. http://www.palmos.com/dev/tech/docs/ is the Palm developer documentation site. As well as providing specs for the pdb format it also has other documentation that might be useful to you during the design phase. If you do end up writing code to read and write your own pdb's feel free to pass questions in my direction. I've already done some of this. There's also some good information up on the web that a search should find. Sorry for being vague but it's been a long day and I'm too lazy to look up any references.
