xBrowse-TMySql sample?

Postby FranciscoA » Mon Apr 02, 2012 2:33 am

Greetings to all.
Can any of you show me an example tmysql xbrowse in which the xbrowse be refreshed after a consultation?

Let me explain: When I use oQuery: locate (), achieving the goal, but is too slow. If I use oQuery: Seek (), the key value is found, but the xBrowse not select the line that corresponds. Even moving the cursor.

Appreciate very much this small example TMySql and xBrowse.

thanks

Maybe an oBrw:refresh() might work??
Thank you

Hag, thanks for your reply. I did it but not worked:
oQuery:Refresh()
oBrw:Refresh()


Shuming, I will try your modifications.
Thank you very much.

obrow:=bseek:={|v|odb2:SEEK(v,,{oquery:itemid+oquery:id2})}

Should be
obrow:bseek:={|v|oquery:SEEK(v,,{||oquery:itemid})}

Hello Shuming.
Thank you for your interest in helping. I tried to create tmysql.lib, but I have problems. This is the first time I try to do it.

In compiling this error is show:
