hi i am creating a windows application that will take a binary file as input and this binary file is on the my website so when i download it from the website it should directly go into the window's application for processing how do i do

Hi,
There are two solutions that comes to my mind at this point.(i am assuming the website you have mentioned is under your control)

1) you store the file on an FTP server , and then use the FTP class provided in .net to check if there is file available (Also we can use a date time stamp to check if we really want the file), then download the file and run the file using "Shell".

2) using a web service , you write a web service which will provide the file to you , then from windows application call the web service , get the file and run using "Shell".

Please let me know if this what you want(Let hope Smile | :)

) , i am just trying to give you direction to think , if you need more help let me know .

You can use filesystemwatcher to detect when a file is written to a specified directory.

hi GURUs my myself Vinod
i am an amature in network programming
as an assignment for my final year i have picked up LAN messenger
actually there are many questions but 1st things 1st
*
HOW DO I GET THE NAMES AND IPADDRESS OF ALL THE COMPUTERS IN MY OFFICE?????????????????
*
Desperately waitin for ur reply
n thx a million in advance Smile | :)

Hi Vinziee ,
You can try the following code , also do not forget to Import System.Net
In the following example we use the service of DNS , first we find the host of current computer
then try to get list of computer from this DNS. I hope this works .

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        GetAllIP()
    End Sub
    Public Function GetAllIP() As Integer

        Dim strHostName As New String("")
        strHostName = Dns.GetHostName()
        Console.WriteLine("Local Machine's Host Name: " + strHostName)
        Dim ipEntry As IPHostEntry = Dns.GetHostEntry(strHostName)
        Dim addr As IPAddress() = ipEntry.AddressList

        Dim i As Integer = 0
        While i < addr.Length
            TextBox1.Text = TextBox1.Text & vbCrLf & String.Format("IP Address {0}: {1} ", i, addr(i).ToString())
            System.Math.Max(System.Threading.Interlocked.Increment(i), i - 1)
            Application.DoEvents()
        End While
        Return 0
    End Function

Hi!

I am currently doing a project that involves automated logging-in on web accounts. I used the webBrowser control for this purpose and so far everything is working fine.

However, the method I use is: webBrowser1.Document.GetElementById("btnSubmitURL").InvokeMember("click");

The problem comes in when the button elements do not have name or id properties. Is there a way to invoke the click event without knowing the name or id of the button element?

The only other method I know is GetElementFromPoint(), but it would be good if there is another way since this method requires knowledge on the coordinates of the button.

Thanks everyone.

dear sir,
i am trying to access reddit.com through c# code.
i am using this code:

public void Prepare_Url()
{
try
{
string response = Send_Request("http://www.reddit.com", null);
string postdata ="op=login-main&user=yogeshyahoo&passwd=yogesh&id=%23login_login-main";
response = Send_Request("http://www.reddit.com", postdata);
txtResponse.Text = response;

}
catch (Exception ex)
{
Console.WriteLine("Exception" + ex.Message);
}
}

public string Send_Request(string link, string post_data)
{
//try
//{

string url = string.Format(link);
HttpWebRequest request = (HttpWebRequest )WebRequest.Create(url);

request.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.20) Gecko/20081217 Firefox/2.0.0.20";
request.Method = "GET";
request.Accept = "text/xml,application/xml,application/xhtml+xml,text/html,application/json, text/javascript;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5";

request.KeepAlive = true;

request.ContentType = @"application/x-www-form-urlencoded";
request.Referer = string.Format("http://www.reddit.com");
request.CookieContainer = new CookieContainer();
request.CookieContainer.Add(cookies);
request.Timeout = 600000;
request.AllowAutoRedirect = false;
//equest.Credentials = new NetworkCredential("yogeshyahoo","yogesh");
request.PreAuthenticate = true;

if (post_data != null)
{//post the data to the desired link
string postData = post_data;
request.Method = "POST";
byte[] postBuffer = System.Text.Encoding.GetEncoding(1252).GetBytes(postData);
Stream postDataStream = request.GetRequestStream();
postDataStream.Write(postBuffer, 0, postBuffer.Length);
postDataStream.Close();
}
string s;
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
cookies.Add(response.Cookies);
Encoding enc = System.Text.Encoding.UTF8;
StreamReader sr = new StreamReader(response.GetResponseStream(), enc, true);
s=sr.ReadToEnd();
return s;
// }
//catch (Exception ex)
//{
// MessageBox.Show("Error: " + ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Information);
// Console.WriteLine(ex.Message);

// return string.Empty;
//}

please does anyone have an idea if i can use just any bluetooth with a project that involves using a pair of bluetooth for data acquisition . i hope i dont have to write another code for the bluetooth before i can use them.

Started to read WCF recentenly. I have couple of questions

Suppose I have two classes Class1 and Class2

For Class1 -- IClass1 is the interface
For Class2 -- IClass2 is the interface

How do i expose these interface using one service

<services>
<service name="MyService">
<endpoint>
address = "net.tcp://localhost:8000/Class1/"
binding = "netTcpBinding"
contract = "IClass1"

<endpoint>
address = "net.tcp://localhost:8001/Class2/"
binding = "netTcpBinding"
contract = "IClass2"

My questions
1) in the adress where i used Class1 and Class2
can i use anything for class1 and class2 or should it be Class names or it
should it be servicename ?
2) Every time i expose an interface should i expose at different ports or can i expose at the same port if i expose them at the same port should the binding be different or for the same service can i expose two interfaces with the same port and with the same binding

Iam new to WCF so please let me know if iam not making any sense

1) You don't have to use the class name.
2) You must use different ports, as each interface (service) will have its endpoint.

If i have one service but two endpoints and each end point pointing to a different interface. Then will they have to use a different port every time. That means suppose if i expose my methods using ten different interface then each interface should expose thorugh a different port.

In my company situation i have 20 business layer dll's and each dll has its own interface. If i need to convert this into wcf application and if i want to use only one wcf service and 20 end points in this situation then ecah end point should use a different port ??

If you use different URLs for the endpoint, then it's OK, for example:
http://localhost:9000/ServiceA/
http://localhost:9000/ServiceB/

Hello,

I have created a datagridview using C# windows application and I am having formatting issues with the data once the datagridview has been populated. The way I have this set up is before I bind the data to the binding source I add a new row which contains combo boxes. These Como boxes are used to populate the new headers. Once the headers have been modified the data needs to be formatted to data types the system can handle. For example, the datagridview populates dates as mm/dd/yyyy 00.00.00 AM but I need to reformat this to mm/dd/yyyy. I have created a method that loops through each cell in the first row and captures the new header (which works) but when the code that is suppose to reformat the column runs, it doesn't work. the code I have to reformat the columns based on the logic used is dataGridView1.Columns[c].DefaultCellStyle.Format = "d";. However, this doesn't work. Can someone please help me? It is much appreciated. Here is what I have and if it is not enough then let me know and I can post more code.

private void button10_Click(object sender, EventArgs e)
{

if (radioButton1.Checked == true)

{

string[] newHeaders = new string[dataGridView1.ColumnCount];

int n = dataGridView1.ColumnCount;
int c = 0;

for (c = 0; c < n; c++)
{
newHeaders[c] = dataGridView1.Rows[0].Cells[c].Value.ToString();

if (newHeaders[c] == "A1ORDT")
{

dataGridView1.Columns[c].DefaultCellStyle.Format = "d";

}

}

}
else if (radioButton2.Checked == true)
{
//Add code for custom formatting
}
else
{
MessageBox.Show("Please select standard or custom formatting");
}

}

I have a Person class with firstname and lastname properties. I have personList class that contains a list of persons and i have attached it to a listbox. When i display the list box, it grabs the toString() method of person class and displays it. Instead I would like to show the first and last names aligned as two different columns so that it could be viewed better.

I have tried the multi column property, but it takes the next item and puts it in the next column. Can this be achieved in a list box ?
Should i customise the display using the DrawItem event

please let me know.
thanks,
kaer

Owner drawing may be an alternative, but I think you'd be better if you used a ListView (with the View property set to Detail) or a DataGridView

Thanks dave..
Which would be a better alternative..A listview or a DatagridView with respect to performance and ease of use... the data in the list will be around 50 and i wouldnt need any specific features other than displaying the data in columns and handling the selection event

Having used listviews extensively in an app but only having prototyped the DataGridView, I tend to lean towards the latter.

A list view is a less complex control (it's the file list from windows explorer). A DataGridView is a much more full featured, and complex, grid. If you're databound a DataGridView has native features to populate data. If you're not databound you can still do so easier by doing something like mygrid.addrow(firstItem, secondItem, thirdItem). With a listview afaik you have to create a new row item, use it's addSubItem method to add each value one at a time, and then finally add the row to the grid. There might be gotchas I'm not aware of but the DataGridView seems to be easier to use and has a much richer set of features. If you ever had to do anything fancy in the grid you'll have to use the latter anyway so you might as well start with it.

EDIT: The listview will have semantics somewhat closer to that of the listbox. However it's still different enough that it's not a plug and play replacement.

I"m using this CMT universal tool to migrate emails from Lotus to Exchange. During the migration a lot of outlook reminders boxes popup and once the migration finish, those diaglog boxes won't allow the CMT tool to go to the next user until someone click OK on that diaglog box.

I tried to write an application that get the outlook takes and closes it out, however I don't want to close outlook if there aren't any diaglog boxes there. I'm having a hard time trying to figure out how to write a script that would click close that diaglog box.

Hi there,

I heard that if we remove even a single byte from an exe file/application (irrespective of its size), then, the entire file/application would disfunction or become an invalid Win32 application. I searched Google, MSDN thoroughly, but did not find any link. So, I thought about consulting you guys. So, please tell me how to remove a byte of an exe file or overwrite its contents with that of my code?

Your help will be truly appreciated,
Thanx,
Rajdeep.NET Smile | :)

depends which byte you remove i guess, if you remove part of a variable value then it probably wouldnt make a difference, i not sure thou

Life goes very fast. Tomorrow, today is already yesterday.

1: I don't think to be possible replace some part of an .exe, if you delete,add overwrite some part it becomes invalid.
2: How can you know which byte to replace???
3: Why you need to do that?
