thanks that fixed it!
Last question:
_connectionString = ConnectionManager.ConnectionStrings["connection_string_stored_in_config_file"];
where do you specify ConnectionManager?
Thanks again!

Sorry, that should have read ConfigurationManager.ConnectionStrings; add a reference to System.Configuration . This is what happens when I write code directly on the Code Project web site. I'll edit the original code to show what it should be.

I am using visual studio 2008....
Thanks for that!!! I hope this is the last question!!! Its still not liking ConfigurationManager. Does not exist in current context. Am I supposed to initialise this somewhere?
Also in this part of the code "connection_string_stored_in_config_file" is this the section in the config file?
Here is how my code looks:
using System.Configuration;
namespace testapp
{
public static class Settings
{
private static string _connectionString = string.Empty;
public static string ConnectionString
{
get
{
if (string.IsNullOrEmpty(_connectionString))
_connectionString = ConfigurationManager.ConnectionStrings["connection_string_stored_in_config_file"];
return _connectionString;
}
}
}
}
Here is my App.config file. Is this correct so far and how do I put my connection string in?
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<connectionStrings>
<add name="MyConnection" connectionString=""></add>
</connectionStrings>
</configuration>

You need to add a reference to System.Configuration. It's not included in your list of references - right click on your reference, select Add reference and choose it from the .NET tab.

Now that we know what you are going to call your connection string, change this line to:
_connectionString = ConfigurationManager.ConnectionStrings["MyConnection"].ConnectionString; The connection string you add in here largely depends on the database type and connection details. There is a handy online resource that shows many different types of connection string - it's available here[^].

Can't be done. Every file can be copied and anything you put on the screen can be captured by any decent screen capture prog.

For some reason, I have trouble capturing frames from video that plays on my computer. I wonder if that could be utilized to prevent a screen capture of an image. I think it has something to do with hardware acceleration, though it may be a quirk of my video card.

Embedding them and encrypting them could make it at least difficult to copy files.

In your video case it might be because the video player is using DirectX. There are programs out there that can grab DirectX output images. You just need to do a search on that. You may want to take a look at this article: Various methods for capturing the screen[^]

PrtScrn hes problem capturing DirectX video as well as otehr windows that use transparency. PrtScrn sucks but is easily replaced by other screen capturing apps that do a much better job and don't have the limitations of PrtScrn.

Copying the files is easy. Decrypting the data is harder.

Yeah that'll be the hardware acceleration, what windows actually puts up is some predefined overlay colour and the graphics card graciously fills this colour in with the video as it passes through. So when you take a screen capture you just capture a dark purple block.
If you find what the overlay colour is you can fill a block of it in inside ms paint, and watch any currently playing videos on it.
My current favourite word is: Smooth!

I always wondered why it did that. Thanks for the info!

How to get selected item for DropDownList .And this DropDownList is inside GridView.

"In the DropDownList Tasks menu, choose Edit DataBindings.
The SelectedValue property of the DropDownList control is selected in the DataBindings dialog box."
See here for a walkthrough.

SqlConnection con1 = new SqlConnection();
con1.ConnectionString = ConfigurationManager.ConnectionStrings["Connectionstring"].ToString();

con1.Open();
SqlDataReader dr = cmd1.ExecuteReader();
while (dr.Read())
{
return dr["ZoneCode"].ToString();
}
con1.Close();
Error:
Compiler Error Message: CS0161: 'Adv.ReturnString(string, string, string, string, string, string)': not all code paths return a value

Remove the return from inside the while loop and place it outside.
Return a collection of ZoneCodes instead of doing what you have done above.
<pre>SqlConnection con1 = new SqlConnection();
con1.ConnectionString = ConfigurationManager.ConnectionStrings["Connectionstring"].ToString();
string sql1 = "select " + colu + " from " + tbl + " where " + cond1 + " ='" + value1 + "' and " + cond2 + " = " + value2 + "";
SqlCommand cmd1 = new SqlCommand(sql1, con1);
con1.Open();
SqlDataReader dr = cmd1.ExecuteReader();
List<string> objList = new List<string>();
while (dr.Read())
{
objList.Add(dr["ZoneCode"].ToString(););
}
return objList;
con1.Close();</pre>
You method signature will be
<pre>public List<string> ReturnString(string tbl, string colu, string cond1, string value1, string cond2, string value2)</pre>
Sorry. I cannot include this code in the <pre> tags. The generics part is getting messed up.

You need to include the Systems.Collection.Generic namespace.
