The error message is about a method in the Form1 class, but there is no Form1 class in the code that you have shown.

code:
try
{
DirectoryInfo dirInf = new DirectoryInfo("C:\\Windows\\Temp");
foreach (FileInfo fileInf in dirInf.GetFiles())
{
fileInf.Delete();
}
}
catch (System.Exception ex)
{
lbl.Text = ex.Message;
}
But: it can't delete to file is using by another processes.and it's stop here.
I want it skip this file and continue program. Can u help me?

add a second try-catch surrounding the fileInf.Delete line, so the foreach loop
continues no matter what. You can choose to keep the catch block empty, or
you might maintain a list of files that failed to delete and show it somehow when
the loop is done and the list is not empty. Dont do a MessageBox for every
single failure, that may annoy the user a lot...

Hello!
I have written a C# program and I set a file to start my program when I double click it. How can I find path of the file which has started my application? HELP!
|
|
|
|
|
if you double-click a file with a known extension, it launches its app
and Windows Explorer puts the full file path on the command line.
So you need to grab the command line; you get it (split into parts) as
the parameters of your static Main method. Alternatively you can access it
through some classes, e.g. Environment.CommandLine (not split, and includes
the path the app itself in front).
BTW if you select multiple files, then double-click, they should all
appear on the command line, so you may want to iterate over all the parts
of the command line.

I dont know why this is so hard. I just cant get it to work!!! I've tried a million things and different ways. I get this error: WebService1.Class1 cannot be serialized because it does not have a parameterless constructor.
public class Class1 : System.Web.Services.WebService
{
public string _strOne;
public string _strTwo;
public Class1(string strOne, string strTwo)
{
this._strOne = strOne;
this._strTwo = strTwo;
}
[WebMethod]
public Class1 HelloWorld(string str1, string str2)
{
return new Class1(str1,str2);
}
}

So have you tried to add parameterless constructor?

Yeah. Now i get this error. System.NotSupportedException: Cannot serialize member System.ComponentModel.MarshalByValueComponent.Site of type System.ComponentModel.ISite because it is an interface.
Here is my code.
Ughhhhhhhhhhh
namespace WebService1
{
///
/// Summary description for Class1
///
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ToolboxItem(false)]
public class Class1 : System.Web.Services.WebService
{
public string _strOne;
public string _strTwo;
public Class1()
{
}
public Class1(string strOne, string strTwo)
{
this._strOne = strOne;
this._strTwo = strTwo;
}
[WebMethod]
public Class1 HelloWorld(string str1, string str2)
{
str1 = "1";
str2 = "2";
return new Class1(str1, str2);
}
}
}

Have you tried adding the constructor?
public Class1()
{
}Types can't be serialized if they don't have a default (parameterless) constructor.

The text is only going to align within the label itself, so if you want it to align within the panel, it needs to be the same size as the panel.

Hi All,
I have a button "Change PAssword". When user clicks on that it displays a form like:
Old P/w:
New P/W:
Confirm New P/W:
& then a "proceed" button.
whenever user enter all these details & press Proceed, that new password should get overwrite by the one already exists in the database.
How is it possible? Could any one help me on this.....
Thanks in Advance!

Well, I guess you want to write a procedure that takes the id of the currently logged in person, checks if the old password entered was correct for that user, and changes it to the new password. That seems pretty obvious, but we can't offer more help than that because, beyond the trivial overview, the specifics are entirely dependant on the specifics of your database schema.

This is a really trivial process. First, you want to check that the user credentials are correct. If so, check the new password against the confirmed new password. If all is good, then run an update query based on whatever your database schema is.
