    In crystal report .net , we can select the databse source . After I selectso the database urce ( e:g SQLNorthwindDB) , I can only see those available tables but no views . If I using crystal report 8 , I can see both tables and views . There must be an option to filter the option . Do you know about that ?

    You may run the batch which contained the "osql" command"attach" . I used this before and it is successful . You may go to microsoft knowledge base web site to find topic " attach MSDE2000 database" to get the answer.

    My start up form asked the user the correct password , if password is correct , the main form displayed and close the star up form. Dim main as new mainform if passowrd = txtpassword.text then main.showdialog() me.close() else (retry ....) The main form can be displayed , but the starup form still would not be closed , but at the back of main form. Anyone knows ?

    Hi joteke, thank you very much . I have one question to ask : 1. when attach/detach database using osql , we must specified the servername\instance , eg: osql -E -S servename\instance - i sp_attach.sql In Vb.net , we can replace the servername with [local] ( if msde is on local), but osql doesn't allow . How to I do it if I want to create a batch file for this command sp that it can run on diffrent machine (assume that the instance is same)
