ActiveX Control Version related problem

[AnanthaM]

Hi,
I am working as a Software engineer in india. I got a problem with ocx control.

The probelem is My client is using Grid32.ocx control(which is in vc++ver4.2) in his code.
NOw he want to run the same code on( vc++ ver6.0).I am using MsFlexgrid.ocx.

But the problem here is there are some methods present only in Grid32.ocx & not present in Msflexgrid.ocx.
Those are:

short GetSelStartRow();
void SetSelStartRow(short);
short GetSelEndRow();
void SetSelEndRow(short);
short GetSelStartCol();
void SetSelStartCol(short);
short GetSelEndCol();
void SetSelEndCol(short);


The above methods are not present in Msflexgrid.ocx.But i want to use these functions.pl Suggest the possible solution.

2)In our Project ,we are saving the Objectdata in Textn format,intelhex format.While saving the data into a file ,opening the already saved file gives assertion dialog box.Once i press Ignore,
i am able to save the file & open the file.This problem is coming only when i run the code in VC++ver 6.0.where as with vc++ 4.2 there are no assertions.Is there any possible solution for this.
