Convert the two integers into strings, concatenate and assign.

You get the number if digits in j(it's easier to covert it to string and use the Length property)

private static string Add(int i, int j)
{
int result = (int)(i * (int)Math.Pow((double)10, (double)(j.ToString().Length)) + j);

return result.ToString();
}

Be carefull..this method returns the result as a string..as "adding" to integers might be bigger than Int32.MaxValue !

Socket Connection Fails

Hi,

I have a Client Server Application that communicates through
socket.
The Client is a VC++(6.0 version) and the Server is a C# application.
While trying to connect to the Socket from the VC++ application by entering the ip for example in - 012.220.200.001 - format I am unable to connect to the listening Socket. I get 10061 or 10049 exception.
But when I try to connect to the Socket server by entering the ip in the format 127.000.000.001(localhost), I am able to connect.

I want to connect to the Server by entering the ip address in either ways.

Please suggest.

Let me know if I will have to change the listen functionality which is currenty
Socket workerSocket = new Socket(AddressFamily.InterNetwork,
SocketType.Stream,
ProtocolType.Tcp)

IPEndPoint ipLocal = new IPEndPoint (IPAddress.Any, port);
m_mainSocket.Bind( ipLocal );
m_mainSocket.Listen(4);
With Thanks and Regards,

Abraham Chethuvelil

Are you in a local network? ie. Connected to the internet through a router or similar?

Because if you are, and you enter your IP address, you are besically sending the request to the router, which has no idea what machine to pass it on to.
You'd have to set up some port forwarding to get it to work.

Hi!
I think the format of your IP address is screwed.
If you start it with '0' the numbers will be interpreted as octal.
I just tried a ping to "012.220.200.001" and ping told me that it actually tried to connect to 10.220.200.1!

you can do this with below code..

<br />
int i = 1+2+3;<br />
TextBox1.Text = i.ToString();<br />

Hope it will help you.

Hi,
first of all what are you diong ? what you wanna do its yet not clear.

Member 3499052 wrote:
textbox.Text = 1+3+4+5+6

<br />
int i = 1+3+4+5+6; // you can calculate here<br />
textbox.Text =i.ToString(); // here you can convert i to string

Now

Member 3499052 wrote:
int i = Convert.ToInt32(TextBox1.Text);
Label1.Text = i.ToString();

No need for this,

Just write,

Label1.Text = TextBox1.Text;

He wants to write a calculator, where he can type into a textbox "1+2-3*4" and it does the calculating for him.

ie/ you've totally misunderstood the point!

You need an expression evaluator like this[^] one.

Include a reference to his assembly in your project and then do the following:

ExpressionEval eval = new ExpressionEval(txtFunction.Text);
object output = eval.Evaluate();
if (output != null)
{
  // You have your answer. Do what you want with it.
}

Populate outlook and outlook express new email with HTML content from winfom

tsachim13-Dec-07 23:21

13-Dec-07 23:21

hello all,
I need an example how to populate outlook and outlook express with html body.
The user can edit the mail within his client before submission.

The scenario would be like this:
====================================
1. In winform configuration the user will define his mail client.
outlook or outlook express
2. On winform user will click send mail.
3. New mail form of the user client will popup, filled with :
from: , to: and the messaqge body populated with html rendered at winform.
4. While new mail client is open, the user can edit the mail message and the submission action will be triggered by the user.

Thanks
Tsachi

ThreadStateException

Hi to all!!!
I have a class & in constructor I call for "webBrowser = new WebBrowser();"
There I get thread state exception (ActiveX control '8856f961-340a-11d0-a96b-00c04fd705a2' cannot be instantiated because the current thread is not in a single-threaded apartment.).

The interesting thing is that the first time i call that class no exception is made.
Then I destroy that instance and make a newone that throws exception.

I use that class for some gdi+ stuff, I also use background worker.

thx

Hi,

I suggest you create all WebBrowser instances in the main or GUI thread.
Since your class constructor contains "new WebBrowser()" it too should only be instantiated
by the main thread, not by a BackgroundWorker thread.

datagridview checkbox field [modified]

arkiboys13-Dec-07 22:54

13-Dec-07 22:54

There is a checkbox field in the datagridview control.
In the datagridview_cellclick() event I have a condition so that the user is allowed or not allowed to check this box.
Not sure why this does not seem to have any affect because the condition is met correctly but when the grid is populated then the checkbox does indeed appear as if the if statement has no affect.

This is what I am doing in the cellclick event
And there is nothing else that makes that field to have a check in the checkbox field.

if...
...
dgvSecurityPricing.Rows[e.RowIndex].Cells["Price"].Value = false

Not sure why in _CellFormatting event this gets set to true

Thanks
