hi,
I have this procedure to populate the data from forms to excel. This is working fine but I have one problem. In the arguments, I'm passing the title, select statement and for columns, I'm passing 'Y' or 'N'. based on 'Y' and 'N', the column will be shown or not shown in the excel sheet. e.g: if I pass 'Y' for empno, 'Y' for ename, 'N' for sal and 'Y' for deptno then in the excel sheet, empno will be showm on first column, ename on 2nd column, 3rd column will be empty and deptno on 4th column.
Now because third column is empty, I want to move deptno column(4th column) to third column.
This can be achieved if I assign a correct values to variable c. But how to get that exact value, I'm not able to do this. I tried a lot but not successful.
Anybody please help. This is the procedure I'm using
PROCEDURE DYNAMIC_CURSOR (PC$REP_HEADING IN VARCHAR2, PC$SEL_STATEMENT IN VARCHAR2, P_EMPNO IN VARCHAR2, P_ENAME IN VARCHAR2,
P_SAL IN VARCHAR2, P_DEPTNO IN VARCHAR2)

cut and paste (move)
Excelargs := ole2.create_arglist;
ole2.add_arg(Excelargs,'D:D');
ccol := ole2.get_obj_property(ExcelworksheetID,'Columns', Excelargs);
ole2.destroy_arglist(Excelargs);
Excelargs := ole2.create_arglist;
ole2.add_arg(Excelargs,'3:50');
rrow := ole2.get_obj_property(ccol, 'Rows', Excelargs);
ole2.destroy_arglist(Excelargs);
ole2.invoke(rrow, 'select');
ole2.invoke(rrow,'Cut');
Excelargs := ole2.create_arglist;
ole2.add_arg(Excelargs,'C:C');
ccol := ole2.get_obj_property(ExcelworksheetID,'Columns', Excelargs);
ole2.destroy_arglist(Excelargs);
Excelargs := ole2.create_arglist;
ole2.add_arg(Excelargs,'3:3');
rrow := ole2.get_obj_property(Ccol,'Rows', Excelargs);
ole2.destroy_arglist(Excelargs);
ole2.invoke(rrow,'Select');
It is hardcode same but you have to change/generalize as per you requirements.
paste work, you have do your self and i feel u can
