Hi
Read up on System.Diagnostics.PerformanceCounter .

For a general question like this it is best to google first [^]. Generally, people post specific problems here.

Just curious - do you find you get a lot of spam?

Hi,

I have a dataview called 'dvUniv' which contains the sorted data. I want to reassign this sorted data to another DataTable, say dt1. Is it possible to do that? If so, how is it done? Any help in this regard is great.

Thanks,

Hi,

Thanks for your reply. But there is no function called DataView.ToTable(). I'm using .Net Version 1.1. Is there any other way?

Thanks

You could try the following code:

DataView dvUniv = new DataView(dt1);<br />
<br />
            for (int i = 0; i < dvUniv.Count; i++)<br />
            {<br />
                dt1.Rows.Add(dvUniv[i].Row);<br />
            }

Hi,

I have developed a an EXE that would be running on a web browser...At the same time i would like it to accessing the system resuorces. How should i go bout with giving the permissions to this particular piece of code...

Errors happened when I tried to access a toolbar control from other thread. Please show me your all solutions.

Hi All,

I have a toolbar control which is created by using Microsoft.Office.Core.CommandBar. All are good until I have some modification on it from other thread (I changed enable property of one control on this commandbar). The error is look like:

<br />
Unable to cast COM object of type 'System.__ComObject' to interface type 'Microsoft.Office.Core.CommandBarPopup'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{000C030A-0000-0000-C000-000000000046}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).<br />

If this command bar is a Form (or something extends Form), I can use the invoke action and delegate method to solve current problem. But it isn't. Are there any solutions for this issues?
Thanks for all suggestion solutions from you friends.

Erhm, the easiest way is to load all tables in you database in a DataTable object and write that to XML using the WriteXml() method, however working with XML this way is pretty time consuming having large amounts of data in your database...

Have you tried anything to resolve the issue or simply got the exception and posted it here?

It looks like you program is attempted to load an EXE. The exception is security related. What permsissions are set on the EXE? Does the security context the calling application is running under have the relevant permission on the target EXE to do what you are trying to do.

Actualy, what are you trying to do? You've just code dumped.

Hi!

MSDN has a quite extensive documentation about .NET security. This is definitively worth reading, otherwise you won't understand the answers you'll be given.

From your stack trace it seems as if the application is running from a network share. By default, CAS policies grant FullTrust only to applications running from the MyComputer zone, so either copy the files over to your local computer or adjust CAS policies accordingly.

hi,
if u have one form as form1 and other as form2 and u want to show data from form1 to form2 then u can pass the values from form1 through the overloaded contructor of the form2.In form1 u could public properties to hold values for passing and then in the constructor pass these prop vals.I hope its clear.

To get the value of a variable "V" in form "X" from form "Y", expose V as a public property in X, store a reference to an instance of X in Y, and access it. For example:

public class X : Form
{
  // The public property
  public int V {
    get { return v; }
  }
 
  // Private member variable
  int v = 0;
  ...
}
 
public class Y : Form
{
  // Reference to instance of form X
  X x;
 
  void someMethod()
  {
    // x must have been properly initialized!
    int valueOfVinFormX = x.V;
  }
}

While this is probably the easiest way, it's not the recommended method of accessing data in other forms. But since you're a beginner, I decided to post a simple and direct answer.
