Hi,
Are you using Database? and Company_id is a Field?

Hi,
Are you using Database? and Company_id is a Field?

yess...sql.
it is possible we can do auto increment in the database right?but it will just add 1 by 1 and only using 1,2,3 n so on..i want it to be in the other format like C01,C02 and so on..so we must do the coding in the form right?

Yes, Auto increment is possible, but it should be a number, i Think so. But in your case You have mixed the Number and String. So you have to do

> Get the Last Company_id
> Split it into String and Number ( C01 as C and 01)
> Then Increment the Value of Number
> Finally Concatenate the Values

If "C" prefix is fixed for all ID then the extraction is easy.

To extract Use Left () or Mid() function and to Format numbers use Format() function in final concatenation
