Re: Need suggestion !!
You could look at MySQL which works on the Palm and on CE. That would mean C or C++. --- rajesh talasu <[EMAIL PROTECTED]> wrote: > hello everybody, > > i want to develope an GENERIC App. where the code > should work in Palm And Pocket Pc. > > My project needs:- > 1.A database Inrtraction , where i can use SQL > Query. > 2.App. shoud UPDATE my Particular DataBase Table > Through Internet. > > So what platform I shold use to develop my App;such > that i won't be face any problem. > > Querry:- > > Can I use Appforge ? > Can I use J2ME? > > please Guys Reply some suggetsion regarding above > problem. > > > > __ > Do You Yahoo!? > Tired of spam?

Though you probably need to create your own mechanism for SQL-access (though there are solutions that might offer direct SQL, like IntelliSync or Appforge's DataSync). You could also create a small php/perl/asp app that passes SQL queries to the server and then returns the result. > Can I use J2ME?

bizarre blanks problem--need suggestion
This seems bizarre--but I checked it both looking at my PDB file in a hex editor and inspecting the text data in memory. The string I pass to a field has blanks in it between words, but only some of the blanks appear to be respected. in other cases the words are pushed together. I am just calling FldInsert with a char * to get the text in. Anyone seen this?

Why not just use FldSetTextHandle?

Which protocol should i use.....Need suggestion
Hi Guys, Just need your views.I want to transfer files to Central Server I am using Cellular network and TCP/IP to send the files,but found it very very slow. Which protocol should i use, TCP/IP or FTP ? Which one is better and should be used. I have come to know that FTP does not works with Cingular network. Is it true ? I am in great confusion.

Re: Which protocol should i use.....Need suggestion
tcp/ip is low level protocol to transfer data ftp is high level protocol based on tcp/ip so i guess you mixed 2 things together. first make sure what you want and then either choose some high level protocol such as ftp, http or many others, or if none is good for your needs then feel free to invent new one -- For information on using the ACCESS Developer Forums, or to unsubscribe, please see http://www.access-company.com/developers/forums/

Yes you are ... http://en.wikipedia.org/wiki/OSI_model FTP is ON TOP of TCP/IP Probably you mean "use FTP or my own proprietary protocol" ? -- For information on using the ACCESS Developer Forums, or to unsubscribe, please see http://www.access-company.com/developers/forums/
Re: Which protocol should i use.....Need suggestion
That's fine.But here is what i experienced : I used WiFi first to transfer files ,the speed was excellent.I was using tcp/ip and that's low level protocol.There were not too many handshakes in the code, there were no checksum , no verification of packets etc. I then tried using cellular network, but this time with too many handshakes , checksum and verifications,i was using the same low level tcp/ip protocol, but this time the results were very very slow. I then used the cellular network and tried to transfer the file using FTP , it was again slow but not as much as with tcp/ip. I thought this may be the problem of network but when I used the same code in Pocket PC, the results were very very fine as comprared to Palm The main problem of mine is speed. What should i do to increase the speed. I have used too many handshakes while sending the files. May be that is the reason... I am totally confused. What should i do to increas the speed.? Note-- The palm is using bocking socket but the server is using non blocking socket.This may be the issue as when Server used the blocking socket , the tranfer was queit fast as compared to this. I am giving you every small detail so that any hidden issue comes out.

Re: Which protocol should i use.....Need suggestion
I use the HTTP/S library from pdadevelopers.com. I have some php code on the server side which then takes multipart/form-data data from a standard http POST and populates a MySQL db but you can do anything with the data. I found this to be really easy since php will automatically parse the data so all I have to do is parse my source data on the Palm side using standard http protocol for multipart/form-data. Personally I find it really easy to write php over most other languages and speed on the server side is not an issue for php over other languages since it compiles into a very quick code on the server side. You may however find that POST with multipart/form-data is slower if you are sending data with alot of parsing since the parser can sometimes be larger them the data. Unless you are send MB of data or using a really slow connection speed you probably wont see the difference between TCP/IP, HTTP and FTP since the time is more dependent on the speed of the connection then anything else. Most Palm data is less then 32kb which sends in fractions of a second once the connection is established. Hope this helps.

Re: Which protocol should i use.....Need suggestion
Hi Shruti, Same problem when i was sending the base64 data of file to the central server.I was sending data in chunks.As i increased my chunk size ,it starts working faster.I used NetLib API to send the file to server and Airtel GPRS connection. Can help you if you can elaborate how u are sending data to server. regards kapil -- For information on using the ACCESS Developer Forums, or to unsubscribe, please see http://www.access-company.com/developers/forums/
Re: Which protocol should i use.....Need suggestion
Hello Kapil Thanks for your kind help. This is the way i am sending the data to the Central Server:- 1--- Opens the connection with the server 2- Sends Header (informing the name of file and other required information) to the server. 2.1 -- Wait until we gets the Header acknowledgment. 3. Opens the file and each time reads and then send the 8k of data to the server. 3.1-- Every next packet is sent after we get the acknowledgment of previous one. 4--- After completion of the file, waits for the file received notification from server and then close the connection and the file. Note -- I am using Checksum with each packet and the socket type is BLOCKING. I too am using netLib API and Airtel Connection.
