Use pb development c/s application for many years, recently in the familiar with pb smartclient model, application development has learned how to use web service development based on web service and invoke the datawindow data browsing, but all case made no mention of data updates should be how to do! Xie Xian you, can you give a direction concept?

Setfullstate getfullstate (), (). http://blog.csdn.net/gac123/archive/2008/11/04/3215990.aspx may have a look

Update process, or to submit SQL statements, or submit the data window

CodePudding user response:

Getfullstate and setfullstate the most simple, but the original poster can see the network traffic, bigger scary, suggest or text, update into SQL statements

CodePudding user response:

Suggest using getfullstate and setfullstate,
The text, into the may go wrong (if the content contained in the PB may use segmentation symbols TAB)

CodePudding user response:

. Well, in the getfullstate/setfullstate getchanges/setchanges plus zib2 libraries on the basis of the function can provide compression and decompression, general data ~ ~ it is recommended to use this way

CodePudding user response:

I also in the study, if only by transfer script, such as text mode, but if not meet with huge data update content estimation, as if also can not pass structure?

Pb8 method seems to be a good to learn, thank you,



Remark & amp; stow

CodePudding user response:

In favor of the text to update, change line status, as to the TAB symbols, etc., the client can test first

CodePudding user response:

Within the local area network (LAN) using not too big problem
The Internet if there are any narrow band, and often have a big report, influence is very big, consider having a for blob compression decompression algorithm
