Re: How can i controll an email through C# - C# Discussion Boards

Hi All,

In C++ i used the method "SetWindowsHookEx" to set this hook.

Is there is some easy way in .NET to do it ?

Thanks.

Well, the easiest way, would probably be to use SetWindowsHookEx!

C#

using System.Runtime.InteropServices;
...
public enum HookType : int
{
     WH_JOURNALRECORD = 0,
     WH_JOURNALPLAYBACK = 1,
     WH_KEYBOARD = 2,
     WH_GETMESSAGE = 3,
     WH_CALLWNDPROC = 4,
     WH_CBT = 5,
     WH_SYSMSGFILTER = 6,
     WH_MOUSE = 7,
     WH_HARDWARE = 8,
     WH_DEBUG = 9,
     WH_SHELL = 10,
     WH_FOREGROUNDIDLE = 11,
     WH_CALLWNDPROCRET = 12,    
     WH_KEYBOARD_LL = 13,
     WH_MOUSE_LL = 14
}

delegate int HookProc(int code, IntPtr wParam, IntPtr lParam);

ImprortDll["user32"]
public static extern IntPtr SetWindowsHookEx(HookType idHook, HookProc lpfn, IntPtr hMod, uint dwThreadId);

If you've tried to do it, and came accross a problem, then give more detail about what you tried and the problems you encountered.

Once you've given sufficient information, people will actually be able to help.
For example, if i asked:

"I have made some code to merge two databases, how can i separate them again?"

Nobody knows how I merged the two databases, or anything about the databases themselves. How on Earth are they going to be able to help?

ok this is my first time to try to ask about help

this is my code i used to do

//Server code
private void button4_Click(object sender, EventArgs e)
{

TcpClient clientSocket = new TcpClient("10.40.145.212",110);
NetworkStream NetStrm = clientSocket.GetStream();
StreamReader RdStrm= new StreamReader(NetStrm);
tbStatus.Text += RdStrm.ReadLine();
sendPOP3cmd("USER "+ "Panel@wireless.com" + "\r\n",NetStrm);
sendPOP3cmd("PASS "+ "panel"+ "\r\n",NetStrm);
string Data = sendPOP3cmd("STAT\r\n",NetStrm);
string[] BreakDown = Data.Split(" ".ToCharArray());
int messageCount = Convert.ToInt32(BreakDown[1]);
for (int i=1;i<= messageCount;i++)
{
StringBuilder message = new StringBuilder("");
Data = "RETR " + Convert.ToString(i) + "\r\n";
byte[] szData=
System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray());
NetStrm.Write(szData,0,szData.Length);
string szTemp = RdStrm.ReadLine();
while(szTemp!=".")
{
message.Append(szTemp);
tbStatus.Text += szTemp+"\r\n";
szTemp = RdStrm.ReadLine();
}
if (message.ToString().IndexOf("free money")>0)
{
sendPOP3cmd("DELE " + Convert.ToString(i) +
"\r\n",NetStrm);
}
}
clientSocket.Close();

//searchFor(ID)

//searchFor (xxx);//put the ID you have read in here);
}

private void searchFor()
{
throw new Exception("The method or operation is not implemented.");
}
public string sendPOP3cmd(string cmd,NetworkStream NetStrm)
{
byte[] szData;
string returnedData = "";
StreamReader RdStrm= new StreamReader(NetStrm);
szData =
System.Text.Encoding.ASCII.GetBytes(cmd.ToCharArray());
NetStrm.Write(szData,0,szData.Length);
returnedData = RdStrm.ReadLine();
tbStatus.Text += cmd + "\r\n" + returnedData + "\r\n";
return returnedData;
}

first i have to click on the button to connect to the server through local network, but when i display the emails all of the emails display but i need the latest one only.

another thing is how to cut the email i get into parts for example the name and the email address that i can take the email address then search the Data base i have created

hi
how to find CD-RW Drive?

tanks

What I usually do is press every button on the front of the computer until one of those CD drive thingies pops out.
This can take a while as I usually end up pressing the "off" or "restart" buttons in the process.

Alternatively you could check out this which I googled in two hits with "c# find cd drive": Clicketty

You always pass failure on the way to success.

The resolutiion of the original image is much higher than that it'll be displayed in page coordinate.

It's possible to make it clear in page coordinate, any way?
Thanks very much.

how about Graphics.ScaleTransform (Single, Single)?

and ... Graphics.SmoothingMode = HighQuality ?

Thank you.
Try.

It doesn't take effect.

Hi All,
I have a TableLayoutPanel on a form and I want to let the user drag and drop objects on to it. I need to find out on which cell the dragged object has been dropped. is there any way to do it?

Thanks a lot

Aref

Hi there,

What I would do is to create inside each cell a full-docked control, like an empty label, then on the TableLayoutPanel DragDrop event I'd get the cell by the position of the control:

private void tableLayoutPanel1_DragDrop(object sender, DragEventArgs e)
{
Point p = tableLayoutPanel1.PointToClient(new Point(e.X, e.Y));
Control c = tableLayoutPanel1.GetChildAtPoint(p);
TableLayoutPanelCellPosition cellPos =
tableLayoutPanel1.GetCellPosition(c);
}

Try it, it's working.

The cell that gets the drop is reprisented by cellPos.Row and cellPos.Column

Hope that help.

Danny

Hello danny,

What is the relevance of creating a full docked control as you have explained. It will be great if you could spare some time to explain.

Thanks,

CPM

... because this code works only if there is some control at clicked position.

tableLayoutPanel1.GetChildAtPoint(p)

... would return null without the full docked control at the background.

Hello,

how can I create a littel process that listen to the
windows security when we enter the username and password?
I created a process that listen to all keyboard clicking
but it doesnt catch the security windows window (you know, when the
computer lock or something)
thanx.

If you can give me one, just one proof that this would be something beneficial to others for reasons that are NOT selfish then I'll help.

But I tell you, it's going to be VERY hard, because what you are trying to write is Spyware. Malware is not acceptable by good and decent devs.

I'm really hoping that this is some kind of joke question. Because you really shouldn't have any reason to need this. And if you have a reason, then there is a much better alternative.

There is absolutely no justifiable reason for needing to write this type of software.
