Incorrect. The passed parameters will not change if they are immutable (e.g. a string) or if they are value types (e.g. int, double, DataTime)
If the types are reference types that are mutable (and the vast majority are) then there is every possibility that the object passed as a parameter can itself change. But you cannot change it to another object.

Hai iam working with list and i have added items to list and how can i find whether the items r added to list or not using windows applications using c# and how can i display the items in list in windows applications plz any one help me in this problem

if it is a listView control or it's a collection type in both cases u can check by calling the "Contains" function of both classes. This function returns true or false.
and to display those just add them list.items.add(item)

What about CRC? I think that produces a smaller result.

How do you find anything else you're looking for? You search for it. That's what the "search comments" function is for. What did you think it would do?

Hi to All,
I am trying to handle excel file in my application. Here I am trying to get a cell value in the text box on the event of button click. but whenever i run it shows exception that Access is denied..... my code is as follows....
private Excel.Application oXL=null;
private void Button1_Click(object sender, System.EventArgs e)
{
InitializeComponent();
oXL = new Excel.ApplicationClass();
oXL.Visible = true;
Excel.Workbook oWB = oXL.Workbooks.Open("D:\\Pravin\\October-07\\xls\\7starcare-October.xls",0,true,5,"","",true,Excel.XlPlatform.xlWindows,"\t",false, false, 0, true);
Excel.Sheets oSheet= oWB.Worksheets;
Excel.Worksheet oWS = (Excel.Worksheet)oSheet.get_Item(1);
TextBox1.Text= Convert.ToString(oWS.Cells.get_Item(1,1));
}
But whenever i run my application it shows exception as follws ....
------------------------------------------------------------------------------------------------
Access is denied.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.UnauthorizedAccessException: Access is denied.
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true">, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET write access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.
----------------------------------------------------------------------------------------------------
how can i remove this problem?

You need to grant the ASPNET machine account, which your site is running under in IIS, read permissions to the file. You can do this in Windows Explorer by right-clicking on the file and selecting the 'Security' tab.

Hey there,
I am new to this language and have been looking at the example program at the link below:
http://www.codeproject.com/dotnet/twaindotnet.asp
but what i wanted was when the image is returned from the scanner, is to convert it to a Bitmap. I have tried numerous ways to convert the ImgPtr but get an ExternalException at runtime. The example seems to use another class to save and display the image, but I would prefer to handle a Bitmap.
Any help would be greatly appreciated
Thanks
Pete

You're probaqbly getting back a HBITMAP, there is a Bitmap.FromHAndle or Bitmap.FromHBITMAP, isn't there ?
