Thanks problem with connection string eyeseetee9-Jun-08 23:00 eyeseetee 9-Jun-08 23:00  Hi I declared a connection string in my page_load event. So ive got this: string connectionString; SqlConnection con connectionString = ConfigurationManager.ConnectionStrings[project].ConnectionString; con = new SqlConnection(connectionString); Now when I try and reference con.open(); in a different event e.g. onclick it doesnt work. However when i delclare: string connectionString2 = ConfigurationManager.ConnectionStrings[project].ConnectionString; SqlConnection con2 = new SqlConnection(connectionString2); in the onclick event it works. If you declare in page_load does it not work in a different event? any help would be great! cheers We are not a Code Charity Re: problem with connection string Pankaj Garg9-Jun-08 23:09 Pankaj Garg 9-Jun-08 23:09  i think after postback , it initiates the variable form the scratch If you have an apple & I have an apple and we exchange our apples, then each of us will still have only one apple but if you have an idea & I have an idea and we exchange our ideas, then each of us will have two ideas! Re: problem with connection string eyeseetee9-Jun-08 23:28 eyeseetee 9-Jun-08 23:28  So do I need to put the connection string in a postback check as well then? We are not a Code Charity Re: problem with connection string meeram3959-Jun-08 23:45 meeram395 9-Jun-08 23:45  HI, Please try to put the Connection strings and variables outside the IsPostBack and check. It will work. Meeram395 Re: problem with connection string eyeseetee9-Jun-08 23:54 eyeseetee 9-Jun-08 23:54  Ive tried that already. I delcare the name connectionString and con at the top of the page. I have then specufy connection string code in the page load.: connectionString = ConfigurationManager.ConnectionStrings[project].ConnectionString; con = new SqlConnection(connectionString); However I cannot reference it once outside of the page_load say in an onclick event. it recognises the con.open(); but doesnt perform the query. There is no mistake with the query, it works fine. Ive got the query in a try/catch/finally statement would this affect it? Thanks for the help, really puzzling me. We are not a Code Charity Re: problem with connection string meeram39510-Jun-08 0:04 meeram395 10-Jun-08 0:04  On the button click event, connection is opening properly or are you getting an error? Put the connection details inside a try/catch block and see what error message you are getting? Meeram395 Re: problem with connection string eyeseetee10-Jun-08 0:10 eyeseetee 10-Jun-08 0:10  Ive managed to solve it. I had con.open(); specified more then once throughout my application so I simply deleted all the statements and put just 1 on the page load. Does any1 know why you can only have one instance of a con.open();? thanks anyway for the help! We are not a Code Charity Re: problem with connection string meeram39510-Jun-08 0:20 meeram395 10-Jun-08 0:20  If the connection is already open and then again you try to open the connection with the statement con.open, it will end up with error only. if you really want to put the con.open statement everywhere (which is not recommended), you can do like this: if !(con.ConnectionStatus == Status.open) con.open(); Regards, Meeram395 Re: problem with connection string eyeseetee10-Jun-08 0:22 eyeseetee 10-Jun-08 0:22  Thanks, I dont want to put it everywhere just on the page_load.

I have uploaded the application on server but I want only one person can access the applicaiton at a time. In other words I want only a single instance of my applicaiton running at a time.Remember I am on web applicaiton not window applicaiton. Re: single instance of a Web applicaiton. sidbaruah9-Jun-08 22:15 sidbaruah 9-Jun-08 22:15  If only one person could access it at a time, why would you make it a web application??

Bob Ashfield Consultants Ltd Re: single instance of a Web applicaiton. Guffa9-Jun-08 23:52 Guffa 9-Jun-08 23:52  There is always only a single instance of the web application running, regardless of the number of users, so what you are asking for would not help you at all. What you need to do is to have some kind of login so that you can identify the user, and add a limitation in the login so that only one user can be logged in at a time. Despite everything, the person most likely to be fooling you next is yourself. Re: single instance of a Web applicaiton. eyeseetee9-Jun-08 23:57 eyeseetee 9-Jun-08 23:57  Do this: 1. Have a table with column named logged 2. When user1 has logged in fill column with value e.g. 1 3. If user2 tries to log in check if there is a value in the column 4. if so dont let user log in 5. When user 1 logs out clear column. We are not a Code Charity Re: single instance of a Web applicaiton.
