Windows 2000 and above already does this. Search your Help for RunAs.
Basically, you need two applications. One is running as a service and will accept a command line that you want it to run and a username and password to tell it who to login as. The other is the interface that will get this information from the user and send it to the service for execution.
But, like I said, this already exists in Windows 2000 and above. All you need to do is make sure that the service is running using the Services control panel.

using System;

public static void Main()
{
foreach(int i in Name)
Console.WriteLine(i.ToString());

}
I am getting error "Class1.Name denotes a class where a variable was expected"
How can i make it correct?

You can use static methods on the Enum namespace to get the results you're looking for ( well, at least to return the names ). You can't for each on an enum name.

Hi,
You can enumerate your custom type provided you need to impliment IEnumerable and Ienumerator interface. See my article for more information.;)

I found this example and tryed it
Export DataGrid to Excel By Bhavtosh
It doesn’t work for some reasons for all data passed may be because of the size or browser couldn’t handle it and it's opening in a browser.
I was trying to find an example of passing a DataGrid object from C# to Excel Application and open Excel Sheet instead.
Are there any way to do that?
Please help!!!
Thanks,

I just export to a .csv, then open it in Excel. Excel works out the rest.

If an image is inserted in the RichTextBox at runtime, how to drag/move it inside the RichTextBox with the help of mouse, just like we can move any control on the form during design time.
Please guide

well, thanks for the reply, but that will not solve my problem.
Inserting an image is not the problem, what I want to do is, dgra/move the image that is already present inside the RichTextBox with the help of mouse.

Is the a way to do Copy Paste fom a ListView? I couldn't found anything on this, I tried Clipboard but it requires to trap Ctrl + C / Ctrl + P so I don't have any clue how to accomplish this. Anybody know please help me.
Thanks in advance.

Handling key strokes is the easy part. Handle the ListView.KeyUp event and check the KeyEventArgs.KeyCode and KeyEventArgs.Control properties:
listView1.KeyUp += new KeyEventHandler(OnKeyUp);
private void OnKeyUp(object sender, KeyEventArgs e)
{
if (e.Control)
{
if (e.KeyCode == Keys.C) Copy();
else if (e.KeyCode == Keys.P) Paste();
}
}To copy, grab the selected ListViewItems, pack them in a DataObject, and send to the clipboard. Note that this will only work within the same AppDomain:
public void Copy()
{
DataObject do = new DataObject("ListViewItems", listView1.SelectedItems);
Clipboard.SetDataObject(do, false);
}To paste, you unpack the copied data (if relevent) and insert into the ListView:
public void Paste()
{
IDataObject do = Clipboard.GetDataObject();
if (do != null)
{
IEnumerable items = (IEnumerable)do.GetData("ListViewItems");
if (items != null)
foreach (ListViewItem item in items)
listView1.Items.Add(item);
}
}Note that this code is untested but should give you a start of what you need to do. Implementing drag and drop is not much different.
Again, remember that this will only work within an AppDomain. To copy and paste ListViewItems between two separate AppDomains (ex: two different instances of a Windows Forms application), you need to marshal the data. You could marshal it as a string (encode the selected ListViewItems as a string, then decode it in the other AppDomain), or a number of other things that would be difficult to do in a managed application (like alloc'ing the items in global memory, though with objects tied to a HANDLE (native pointer) that isn't so easy).

I've got a page with two panels. The first panel contains the search parameters (textboxes and drop downs). The second panel shows the results of the search.
On the result page, i allow paging and sorting.
Everything works great if i rebuild the dataset each time i change pages or change the sort. But when I cache the dataset in ViewState and try to change pages or the sort, it just takes my back to the parameter page automatically. Nothing else happens.
Here's my code for the Sort:
<br />
ViewState.Add("str_sortOrder", e.SortExpression);<br />
<br />
DataView dvwResults = new DataView();<br />
dvwResults = dst_searchResults.Tables[0].DefaultView[0].DataView;<br />
dvwResults.Sort = ViewState["str_sortOrder"].ToString();<br />
<br />
this.dgr_searchResults.DataSource = dvwResults;<br />
this.dgr_searchResults.DataKeyField = "aut_companyID";<br />
this.dgr_searchResults.DataBind();<br />
All help is appreciated.

Hi people, is there anything in C# that resembles "org.apache.log4j.PropertyConfigurator"[^]?
I'm looking for something that can loads configuration files and do all the dirty work for me... It should..., for instance:
PropertyConfigurator configurator = new PropertyConfigurator();
configurator.load(configFilePath);
System.Collections.Hashtable params=configurator.ConfigParams;
...
IDictionaryEnumerator enum = params.GetEnumerator();
while ( myEnumerator.MoveNext() ) {
Console.WriteLine("\t{0}:\t{1}", myEnumerator.Key, myEnumerator.Value);
... do whatever else you'd like with the parameters ...
}
...
configurator.save(configFilePath);
If it's not part of dot-NET Framework, any Open Source you'd recommend? Thanks in advance.

There's already a configuration framework in place for the .NET Framework. Read about the IConfigurationSectionHandler interface at http://msdn.microsoft.com/library/en-us/cpref/html/frlrfSystemConfigurationIConfigurationSectionHandlerClassTopic.asp[^], as well as many configuration section handlers that are already implemented like NameValueSectionHandler[^] and others listed as implementations on the documentation for IConfigurationSectionHandler. Using this framework for configuration files unifies configuration - from runtime settings to application settings - for .NET applications.
To read more about how configuration files work in .NET as well as how to implement your own sections, read Configuring Applications[^] in the .NET Framework.
So, if you wanted a key/value pair configuration section, you could reuse the NameValueSectionHandler like so:
<configuration>
<configSections>
<section name="mysettings"
type="System.Configuration.NameValueSectionHandler, System" />
</configSections>
<mysettings>
<add key="opt1" value="myvalue" />
<add key="opt2" value="somevalue" />
</mysettings>
</configuration>To use this in your code:
using System;
using System.Configuration;
class Test
{
static void Main()
{
NameValueCollection settings = ConfigurationSettings.GetConfig("mysettings");
foreach (DictionaryEntry setting in settings)
Console.WriteLine("{0} = {1}", setting.Key, setting.Value);
}
}It's important that your configuration file match the executable name for your Windows Forms application or Windows Service (i.e., if your .EXE is named myapp.exe, then you're .config file is named myapp.exe.config) and be located in the same directory as your .EXE (this means that libraries - .dlls - use settings from the .exe that loads them), or use Web.config for ASP.NET applications and be located in the virtual host root (/), in the web application's root (/myapp, for example, which inherit settings from the virtual host's root Web.config), or in a sub-directory of your application (also named Web.config, but can only override some sections like <authorization>.
All .config files inherit settings from machine.config that is in the config sub-directory of your Framework installation for whichever version the application has loaded (or is loaded into).
You can find more about this from the link above.

I recently did this, and you should note that it may not be enough to have type="System.Configuration.NameValueSectionHandler,System". With multiple versions of .NET installed, I found it to be necessary to expand this to include the strong version information, i.e. "System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089".

In some cases, yes it is necessary, but in most cases - including this case (which I've used countless times, as well as defined my own section handlers) - you can specify a partial name depending on the runtime settings on your machine (so long as an assembly is resolvable using a partial name). For example, if your application was loaded into an AppDomain that loaded .NET 1.1, it would use System.dll as you've described above.
If the AppDomain were created under .NET 1.0, the partial name would match System, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089.
In both cases, however, the runtime settings of your machine as well as enforcement of which runtime was loaded (using the <requiredRuntime> and <supportRuntime> runtime config elements) can change this behavior.
