qt and remote login
Message 1 in thread
Could someone give me some pointers as to how i would go a about implementing a solution where i would use a qt designed remote login client to access a remote database via the internet. I have already implemented the database and i would like to allow users to access it through a client application program with a GUI, installed on their pc, rather than to use a web interface. Your attention is greatly appreciated.

The typical approach would be to write an n-tier application with a server
running on the same machine as the database and a client accessing the server
through a network socket or perhaps using a technology such as SOAP.
You could, of course, write a client that accessed the database directly,
across the network. You are going to have significant security concerns here
but perhaps no less than using an n-tier approach.
Assuming you are still at this level and not asking for specifics on how, for
example, Qt helps you with SQL or with networking, your question really has
nothing to do with Qt and more to do with application design. Perhaps you
could rephrase your question?

Message 3 in thread
Hi
I am working on Qt 3.3.4.
I am using Qt QTable for display of large amount of data.
I have derived QTable to get MyTable to add some new functionalities.
I have a server program that is almost, a type of database that sends data
for every 10 minutes or so.
I have a table that has records added and deleted as and when required
depending on request on server-end.
Now, for the first time, I shall retrieve the complete data table. Next,
time i need to refresh the screen after few minutes.
I have records newly added and also few records deleted at any position(not
known). I do not want to delete the table and recreate or clear all rows and
then again insert completely. Can anyone please suggest
techniques/methodologies so that I refresh the screen properly with new
insertions and deletions without flickering?
Thanks & Regards
Deepa
