hi friends. Im currently working in integrating GR Fingerprint SDK with vb.net application. I am using MSSQL 2008 as my database and vb.net as the front end. I have completed almost 90% of the application and im stuck in integrating this SDK with my application. It has an error such as Unable to connect to database and also grfinger is not initialized cannot be converted to double and stuffs like dat. i beieve it is a small error and if someone could personally help me... it would be helpful... hope smeone cn give me a hand in finishing this project of mine...
i have a sample of the project but the database being used was acccess 2007. it is working fine where it can load and stuff... and the only part where db is connected is here
' the database we'll be connecting to Const DBFile As String = "../../../GrFingerSample.mdb" Const ConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source="
so i did the same to my mssql server which is
' the database we'll be connecting to Const DBFile = "../../../FP.mdf" Const ConnectionString = ("Data Source=VKEY-PC\SQLEXPRESS;Initial Catalog=FP;Integrated Security=True")
second error is grfinger is not initialized cannot be converted to double. but i realise that i never use double variable anywhere in my code.
these are the two error is runing my application. please someone cn help me i would be grateful. thank you.
