View 1 RepliesDatabases :: How To Open ConnectionString Using Mysql Connector
Mar 31, 2010environment: W7 Ultimate 64, VS2008, Mysql 5.1.45, Connector .Net 6.2.2
.aspx environment: a DropDownList (DDL) triggers a DetailsView (DV). All functions (select, edit, new ...etc) work fine.
Now, in the same .aspx page I use Event "SQLDSDVKlient_Inserted" to get the Last inserted record ID using "ExecuteScalar" method! This to fill the DV with the just created record using "New" (see code below).
on "cnn.Open()" I get below error msg; Event code 3005!
Some additional info:
a) keep in mind this all happens in the same .aspx page
b) In the MySQL wizard (5.1.45) I clicked the "allow remote connections".
c) the ConnectionString is copied out of web.config (remind you: all 'normal' DV functions work fine.I.e. I certainly can connect to my MySQL DB.)
d) When using, in ConnectionString, the parameters "Allow User Variables=True;old guids = true" I get, on statement "cnn = New Data.SqlClient.SqlConnection(connString)" a msg: Keyword not supported"; so I removed it.
e) without above connectionstring parm I get on statement "cnn.Open()" below error msg: where I need help!
Questions:
1) why does the system suddenly bring the remote connection into play?; I'm always on the same machine, same .aspx page!
2) what is the role of the "mysql connector.net" (6.2.2) in this scenario ?

Databases :: Creating, Opening, Writing To Excel Files?
Aug 5, 2010I am creating an site where a user uploads an excel file to check if any of the records exist in a database. Then they are returned an excel file with only the records that are NOT in the database.
I was thinking I should do it this way1. User uploads their excel file. The app opens excel file and loads records into a dataset (so far this is working with the code below)2. Using datarow and another function to check if each excel record exists in the database3 If the record does NOT exist, and it is the first record tested, create an excel file called records.xlsx and write the record into the file
4. Check the next record and if it does NOT exist in the database, then check if records.xlsx already exists then open it and write it into it.
[Code]....
Hopefully its clear, sorry if its not, I'm a bit of a novice at this. Is this a good way to do it? Does anyone know of any tutorials that might outline how to open an existing file and write to it?
