i need to control a button.enabled property on my Form using a thread but visual studio gives me an exception telling me "Cross-thread operation not valid: Control 'button1' accessed from a thread other than the thread it was created on." and ask me to set CheckForIllegalCrossThreadCalls to false
how can i set it to false??
or if there is another solution for this without setting CheckForIllegalCrossThreadCalls to false
pleas help
thanks allot

CheckForIllegalCrossThreadCalls is a property of the Control class (a parent of Button). The property is not shown in the visual designer but you can easily change its value in code. For example include the following line in the constructor: button1.CheckForIllegalCrossThreadCalls = false;
Though this would suppress the exception, I do not recommend setting CheckForIllegalCrossThreadCalls false, since accessing a control from a thread other than the thread it was created on could lead to unexpected behaviour e.g. freezing of your application. Instead you should use Invoke or BeginInvoke to execute the alteration of the control on the thread it was created on. take a look at this nice article for more info: What's up with BeginInvoke?[^]

MailMessage mail = new MailMessage();
mail.From = "hi2udhay@gmail.com";
mail.To = "hi2udhay@gmail.com";
mail.Subject = "Subject";
mail.Body = "Mail Body Here";
SmtpMail.Send(mail);

If you are asking about the possibility of sending email without using a SMTP server to relay it - that should be possible. You would need a DNS resolver (like this[^]) that would resolve MX records, so that addresses like yahoo.com get converted to the IP addresses of the SMTP servers. You can then use SMTP to talk directly to the SMTP server.

In general you can not.
The only exception I know is with constant strings, where "paul" is the equivalent
of new string('p','a','u','l');
You can of course hide the new keyword inside a method (e.g. a CreateInstance) so the caller
does not have to use new, but then that method would include a new.
|
|
|
|
|
Or use reflection
|
|
|
|
|
hello... well i believe u can't create an instance without the new keyword... u can hook onto a an instance without a new keyword but that instance is also created by new...
what i mean is that
datatable dt=ds.tables[0]...Roughly but remember that you are simply assigning ur reference to an object... similar is sqlcommand command=con.createcommand() example...
but this doesn't mean that u are creatin an instance without new keyword...its simply assigning reference to an object that has been created in createcommand method

Why do you want to do that? What purpose does your request have?
|
|
|
|
|
You can use reflection (MSDN[^]) to do that, but it's a very expensive and roundabout way of doing it.
Like others asked, what's wrong with new?

First, you can easily display XML data by checking the "Ignore HTML tags in this message" option beneath the smilies. As this disables all other formatting-options too, you can alternatively replace all < characters with <.
Second, in the bottom right corner of your posting there is a "modify" link that allows you to modify your post (as the name suggest). Please use this link to change a post with which your not comfortable instead of starting new threads. There is also a remove link, so please remove the "duplicate" posts.
Third and regarding your actual question, take a look at the XmlDocument and especially the Load and SelectNodes methods. The documentation of the class, its methods and the continuative links contain many examples that should give you a good starting point.

You forgot to mention the 'Preview' button when you post a new topic or a reply.
It shows you what your post will look like allowing an oportunity to make changes and correct mistakes/formatting before posting to the forum.

Hi friends,
I am facing a PROBLEM WHILE I send mails with the SMTP class of System.Net.Mail.
The code shows below.
MailMessage mail = new MailMessage();
//set the addresses
mail.From = new MailAddress("from@domain.com");
mail.To.Add("to@domain.com");
//set the content
mail.Subject = "This is an email";
mail.Body = "this is the body content of the email.";
//send the message
SmtpClient smtp = new SmtpClient("mysmtpserver.net");
//to authenticate we set the username and password properites on the SmtpClient
smtp.Credentials = new System.Net.NetworkCredential("user@domain.com", "password");
smtp.Send(mail);
I have a valid smtp server name, username and password. I configured it to outlook and working fine. And wen I test it using telnet port 25 then also its working.
I upload the file to my hosting space. I have two hosting account with godaddy.
The mailing script is working fine in one hosting account. That hosting account have SSL and dedicated IP address.
But the mailing code is not working in the other hosting account. That hosting account is Windows hosting + ASP.NET 2.0 supported.
The error I am getting is as shown as below.
System.Net.Mail.SmtpException: Failure sending mail. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.Sockets.Socket.InternalConnect(EndPoint remoteEP) at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Int32 timeout, Exception& exception) --- End of inner exception stack trace --- at System.Net.ServicePoint.GetConnection(PooledStream PooledStream, Object owner, Boolean async, IPAddress& address, Socket& abortSocket, Socket& abortSocket6, Int32 timeout) at System.Net.PooledStream.Activate(Object owningObject, Boolean async, Int32 timeout, GeneralAsyncDelegate asyncCallback) at System.Net.PooledStream.Activate(Object owningObject, GeneralAsyncDelegate asyncCallback) at System.Net.ConnectionPool.GetConnection(Object owningObject, GeneralAsyncDelegate asyncCallback, Int32 creationTimeout) at System.Net.Mail.SmtpConnection.GetConnection(String host, Int32 port) at System.Net.Mail.SmtpTransport.GetConnection(String host, Int32 port) at System.Net.Mail.SmtpClient.GetConnection() at System.Net.Mail.SmtpClient.Send(MailMessage message) --- End of inner exception stack trace --- at System.Net.Mail.SmtpClient.Send(MailMessage message) at _Default.Button1_Click(Object sender, EventArgs e)
Please help me on this issue....
Thanks in advance....

Some hosting plans disable any outgoing network traffic from the website, except HTTP. You should make sure that is not the case with your account.

Hi
I want to have a MS-WORD template and which should be taken as a input to the C# application. I will have some template variables in that template (.dot ) file those should be replaced during run time by the C# object. Please give some sample to work around this.
Thanks.

Hello everyone,
I am trying to find all methods that have a particular signature. In other words, I want all methods that match the return type and parameter types of a specified method. I have a solution, but I was wondering if a more elegant approach exists. Using delegates is one possibility, but delegates are not very “edit-and-continue” friendly.
Here is my current solution:
void findSimilarMethods()
{
MethodInfo example = this.GetType().GetMethod("ExampleMethod");
ParameterInfo[] parameters = example.GetParameters();
List<MethodInfo> matches = new List<MethodInfo>();
MethodInfo[] methods = this.GetType().GetMethods();
foreach (MethodInfo current in methods) {
ParameterInfo[] currentParams = current.GetParameters();
if ( current.ReturnType != example.ReturnType )
continue;
if ( currentParams.Length != parameters.Length )
continue;
if ( !ParameterEquality(parameters, currentParams) )
continue;
matches.Add(current);
}
}
bool ParameterEquality(ParameterInfo[] a, ParameterInfo[] b)
{
if (a.Length != b.Length)
return false;
for (int i = 0; i < a.Length; i++)
if (a[i].GetType() != b[i].GetType())
return false;
return true;
}
Any suggestions would be greatly appreciated.
-Steve
