You find the correct column from the datagridview's columns[^] collection (which is an instance of DataGridViewComboBoxColumn). Then on DataGridViewComboBoxColumn you have Items[^] collection or DataSource[^].

Through the Value[^] property.

Ok, So I made Dlls in C# in the past but whenever I wanted to use those in another project it has to be in the same place as the .exe, I was wondering if I could story all my dll's in a separate folder from the .exe and still have the program work?
Thanks.

You need to subscribe to AssemblyResolve event of Appdomain class.
|
|
|
|
|
If you have strong-named assemblies (strong name consists of assembly name, version number, culture information, as well as, a public key and a digital signature) you can register them in GAC.
A couple of links to start from:
Global Assembly Cache[^]
Strong-Named Assemblies[^]

Hello everyone,
I am not sure whether it is possible to setup a security policy like this with store procedure. The user account foo could only access database through store procedure, not possible to do other operations, like select/update on the tables of the database directly without using the store procedure.
My store procedure is doing some select/update job. My confusion is, as the user needs to use the store procedure and the store procedure is doing select/update job, then I have to grant the user to have select/update privilege of the database tables? Then the user could skip using the store procedure and select/update database tables directly which causes a security hole. My purpose is to let user use store procedure all the time, no walk around to access database without using store procedure.
Any advice to solve my probleme?
thanks in advance,
George

As long as security concerned a application users sql account should only have the execute permission on stored procedures and should not have any permission on tables. İf you gave the user execute permission there is no need to give specific permission on objects(tabkes views ets) that sp uses.

Thanks Tamer!
I have tested your idea. But met with a issue.
I created a new user which is using SQL Server authentication type. The user default database is AdventureWorks. I grant the user rights of execute one store procedure of AdventureWorks (the store procedure is used to query some specific table) and denied the select rights of the user to select the specific table directly (using table, permission, deny select permission in management sonsole).
But when I tried to use the user to login the management console (in order to test with execution of the store procedure and the select statement), I met with the following error when click login from management console. Do you have any ideas why?
TITLE: Connect to Server

ADDITIONAL INFORMATION:
A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.) (Microsoft SQL Server, Error: 233)

i would like to be able to use multiple components in one place like tabs allow you to layer things and show when u click the tab open. i would like to do this without tabs instead using buttons. i have tried using usercontrol but i couldnt get it to go. if someone could lead me to an example of help me out in some way it would be greatly appreciated. thanks. callum

The natural way to do is it via the TabControl.
If you want to use buttons however, then one idea is putting buttons where you want your tabs to be, and use them to show or hide panels that are the different components you need...

is there any way to have a base panel in my main form then somehow import seperately made panels with all the components as everytime i have tried to use panels i end up droping them within each other. or to simply remove all the border and tabs from tab control?. btw thanks for the fast reply
got it (finally)
UserControl g = new UserControl1();
panel1.Controls.Clear();
panel1.Controls.Add(g);
g.Dock = DockStyle.Fill;
it always ends up being bugger all code -.-

Hi,
I'm trying to implement a drag-and-drop into a list box. The code is copied below.
The problem is that it works fine on my (development) computer but when I share the executable with my colleagues in the office (who're using XP), it doesn't work!
The DragEnter seems to be working (since the cursor changes), but the DragDrop doesn't work (the MessageBox doesn't show).
Can any one help?
Here's the code:
// when a user drags files into the list box
private void MyListBox_DragEnter(object sender, DragEventArgs e)
{
if (e.Data.GetDataPresent(DataFormats.FileDrop)) e.Effect = DragDropEffects.All;
else e.Effect = DragDropEffects.None;
}
// when a user drops files into the image list box
private void MyListBox_DragDrop(object sender, DragEventArgs e)
{
// display message
MessageBox.Show("Drag drop successful");
// pick filenames dropped into the list box
string[] sFileNames = (string[])e.Data.GetData(DataFormats.FileDrop, false);
}
Thanks!

try using httprequest if user is not logging in or filling any data on form.
HttpWebRequest req = (HttpWebRequest)(WebRequest.Create(PostUrl));
req.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0b; Windows NT 5.1)";
req.Method = "GET";
req.KeepAlive = false;
req.Timeout = 1000000;
req.Proxy = WebProxy.GetDefaultProxy();
req.Proxy.Credentials = CredentialCache.DefaultCredentials;
HttpWebResponse res = ((HttpWebResponse)req.GetResponse());
StreamReader sr = new StreamReader(res.GetResponseStream(), Encoding.GetEncoding("iso-8859-9"));
result = sr.ReadToEnd();

How would I capture a screenshot of the computer without the form in it (and whatever's behind it shows up). The form should should be visible (not minimized) on the screen.
So if i start with my desktop and open the form that takes the picture, the form should be visible to the user but the screenshot taken should only show the desktop, without a white hole in it where the form was.
If i opened another application like internet explorer and then opened the form, the form should take a screenshot of the desktop with the internet explorer above it.
|

|

|

Yeah, I've done the same before. When the user clicks the button to take the screen shot, I fire a timer that sets the forms.visible property to false, then take the screen shot, and then form.visible becomes true when finished executing.
wrap it around a try catch finally to make sure the form always comes back into view, i suppose; for saftey's sake.
