In reference to the message posted on the forum, I tried the example sent to me by Cesar Gomez that you can see on the forum and the test works fine, when I copied the test on my application I only changed instead of a dialog I use a wndchild window , the array creates fine but I can't get the function that creates the headers and group headers to work
I have created a small test that uses a child window to show you what the problem is
Initially I open the lotto.dbf file and create a filter because I want to view only the records of a specific year, for example 2022
- Code: Select all Expand view
- oQry := TDatabase():Open( , cdbfPath+"LOTTO", "DBFCDX", .T. )
oQry:setorder(1) //index to data field
cFilter:= "LTRIM(STR(YEAR(FIELD->DATA)))= '" + nyear + "'"
oQry:SetFilter(cFilter)
oQry:GoTop()
later I'm going to create the array
- Code: Select all Expand view
- aArray := Build_Array(oQry)
I create the window with the xbrowse and I go to write the headers
- Code: Select all Expand view
- Build_Title(oQry,oBrw,val(nRecnos))
at this point it gives an error that I do not understand in the file error.log where the error is
