I have a form with a datgridveiw on it, but rather than connecting to a data source (SQL 2005 Express), I want to use a .uld file to do it. I can create the .udl file fine and the connection test works, but I havn't got a clue how to connect to my datagrid, or what the code is and when and where to create the connection and disconnect from it.

I have a search page in my application where I am searching the database for the records that meet the specified conditions that the user selects. All of this works by creating the dataset, datatable, and dataadapter in the code. I then take a created bindingsource link it to the created datatable and then attach the bindingsource to my datagridview to display the results. Now what I am trying to do is to figure the Mean, Median, Mode and Standard Deviation of the results that were found above. My question is how to I run a select query on the code created table. I have the select query I want to use and when I try to use it in the code it talks about the connection. Now I have a dataset that is part of the project and I have the on just for the search page. Let me know if you need any code samples.

View 10 RepliesI'm working on a little script to automate tasks across 12 servers, that are all on the same domain and have a similar setup. The tasks are to create a new folder, to then copy contents off the network into it, and to create a virtual directory in IIS 6 pointing to it. Ideally I'd like to log errors but that's a later concern. My approach was to write a VB Script to connect to WMI on each server in an array, then use it to run off a batch file. While the VBS works if I tell it to create a folder directly, it does not run (any part of) the batch file, nor give me any errors.[code]...

Unable to connect to any of the specified MySQL hosts
Using the mysql command, we can successfully connect to the database. We already checked for any other application or firewall that could be blocking the connection but it seems fine. We also reinstalled the system (no errors during the installation) but the MySQL error message doesn't change.
The system settings are exactly the same as in the other computers. We are using "localhost" as server in the connection string. The "hosts" file has its default values (nothing strange in there).
