Getting - Setting Environment Variables

Hi,

1st. Issue

I have written a package that uses an environmet variable which contains certain information that the user must enter. A sql script task will then get the information from the environment variable and manipulate it.

I don't have a problem programmatically getting information from the environment variable. However, when I manually edit the contents of the environment variable, the changes won't take place unless the box is rebooted. Is there a way to refresh environment variables without rebooting?

2nd. Issue

I have written another package that also reads data from an environment variable but it must also manipulate the data and save the changes to the environment variable.

I have accomplished this programmatically by using GetEnvironmentVariable() and SetEnvironmentVariable(), but unfortunately the changes live during program execution only. Afte the program executes, the changes are wiped out.

How can I make changes stick to environment variables (programmatically)?

-- I found a solution to this:

When programmatically getting and/or setting an environment variable the 'target' parameter must be specified in the method call. By 'target' I mean the location in the registry where your environment variable is stored.

GetEnvironmentVariable( var, target )

SetEnvironmentVariable( OldValue, NewValue, target )

Get values from database query

I have written the following lines

myConnection =New MySqlConnection("server=" + dbServer +"; user id=" + dbUserID +"; password=" + dbPassword +"; database=" + dbName +"; pooling=false;")strSQL ="SELECT * FROM user where type=1;"

user table has name, tel, addr, id, type fields

I would like to know how to use a string array to store the name in the result of strSQL?

Thank you

Hi thtang

You can use fllowing code:

SqlCommand cmd = new SqlCommand(myConnection ,strSQL );

SqlDataReader dr = cmd.ExecuteReader();

while(dr.Read())

{

stringList.Add(dr.GetString(0));

}

get the description of a column

Okay guys heres the senario.

I have written a kick butt asp application that allows me to test sql
statements and manage/display all my databases from the web but I have
a feature I want to include that I can't figure out how. In Enterprise
Manager, one of the column editable properties is the Column
Description. I can't find it in sql server itself. only in the
Enterprise Manager. I need to access it using a sql statement so that
it will display in my table definiation view that I create in the asp
app.These descriptions are kept as extended properties in sysproperties.
Look up sp_addextendedproperty in the help file for more information.
To figure out what Enterprise Manager is doing in situations like
these, you can use Profiler to see what SQL code it is sending to the
server.
