xBrowse: how to retrieve field names...

[nageswaragunupudi]

Mr Rao,

yes it is in my version. I try example with for/loop and :cHeader returns legal string array but :cExpr return "nil"

Code: Select all

for i=1 to len( oBrw:aCols )
        oCol:=oBrw:aCols[ i ]
        var1:=oCol:cExpr                      // returns"nil"
        var2:=oCol:cHeader                  // returns string array with headers...
next
 

I will tray to check why...

Best regards

No point wasting your time. I think the initial implementation was working only for RDDs.

So I suggest you do in your code what we do inside the library in the recent versions:

Code: Select all

   @ 0,0 XBROWSE oBrw OF oWnd OBJECT oQry COLUMNS aFields HEADERS aHead LINES CELL FASTEDIT

oBrw:cExprs := aFields  // Add this line after your XBROWSE command.
 

You can query for the column name with oCol:cExpr

When you upgrade the current versions, you can omit the extra line of code I suggested. Even if you do not omit it does not create any problem
