The default instance on a machine can be reached by connecting to localhost. So, you can try to connect and see what happens. But, if it's no running and not set to autostart, this will fail.

Requirement:
I want to create an application, which should be able to create a file, with the file extension be specified by me. And, when i double click to open that file, it should open it's content in that application. How can this be achieved? ( like word,excel..etc)
Code so far:
For example.. I have created a application with a Richtextbox control to display data,buttons to create a new file, openfile,savefile and to exit. And let my file extension be ".gun".
Time to Answer:
Now, what happens is i create new file, save(savefiledialog) it with .gun extension. This files gets opened when i open it using 'open(openfiledialog) button' which is present in my application. But when i double this file (which is placed on desktop) it opens only the application and not with the content.? How can i get it with the content when the file is double clicked?

Look for method "Main" in your application.
If you have no parameters in it "Main()" then change it to "Main(string[] args)".
If you double-click .gun file, then it is like calling using command prompt:
MyApplication.exe myFile.gun
Just take your .gun file in "args" variable.
|
|
|
|
|
Or just call Environment.GetCommandLineArgs()
|
|
|
|
|
You will need to associate the file extension *.gun with your application - the article http://support.microsoft.com/kb/185453 describes for VB but its basicallyde sticking some info in the registry...

Hi, When i use Main(string[] args) or Environment.GetCommandLineArgs;
it shows me the following error.
Error 1 'string' does not contain a definition for 'rtbFile' (Richtextbox instance)
|
|
|
|
|
|
The error is ok now. and i have done main(string[] args) or Environment.GetCommandLineargs..... But still when i double click the created file(file with .gun extension),, it still doesn't contain the content.
|
|
|
|
|
Just for example :
static void Main(string[] args)
{
string fileToOpen = args[0];
}
|
|
|
|

I dont get what u try to say. This is my code. Can u suggest with this code....(ofdFile=Openfiledialog,rtbFile=richtextbox)
void btnOpen_Click(object sender, EventArgs e)
{
ofdFile = new OpenFileDialog();
ofdFile.DefaultExt = @"*.gun";
ofdFile.Filter = @"Gun Files|*.gun";
if (ofdFile.ShowDialog() == System.Windows.Forms.DialogResult.OK && ofdFile.FileName.Length > 0)
{
//ofdFile.FileName.
rtbFile.LoadFile(ofdFile.FileName, RichTextBoxStreamType.PlainText);
}
}
|
|
|
|
|
And my main function is in Program.cs file
|
|
|
|
|
pass the args[0] to your form class.
static void Main(string[] args)
{
Application.Run(new Form1(args[0]));
}
For example your form class is Form1.
Then change the constructor to
public Form1(string fileToBeOpened)
{
if(fileToBeOpened != string.Empty)
{
}
}
|
|
|
|
|
It shows me 'IndexOutOfRangeException Unhandled' in program.cs
Application.Run(new Form1(args[0]));
|
|
|
|
|
I think you just COPY and PASTE the code.
You must AWARE OF ERRORS.
You MUST check if
args.Length > 0 // you get the file directly
args.Length == 0 // without file
|
|

|

Yes it works. Thanks a lot.

Will get u back if i get more doubts.

this is kinda difficult to phrase, but how can i let a user insert pics into a c# appliaction, and save it so it will show the next time you run the app?
|
|
|
|

You have to build a framework yourself, for how you store the image info ( you can't embedd the images in your actual app ), and to display them. For example, an XML file of image paths, and you then build a list from that, and add pictures to the page dynamically based on this list.

Hi,
kindly check my little script and tell me. where am I doing wrong?
When i run this script the error arises :
==>> No connection could be made because the target machine actively refused it
thank you
private void button1_Click(object sender, EventArgs e)
{
IPAddress host = IPAddress.Parse("192.168.0.102"); // <<-- my machine ip
IPEndPoint hostep = new IPEndPoint(host, 8000);
Socket sock = new Socket(AddressFamily.InterNetwork,
SocketType.Stream, ProtocolType.Tcp);
try
{
sock.Connect(hostep); // <== Error comes from here
listBox1.Items.Add("Connected.");
}
catch (Exception ex)
{
listBox1.Items.Add("Connection problem is :");
listBox1.Items.Add(ex.Message);
textBox1.Text = ex.Message;
sock.Close();
return;
}
try
{
sock.Send(Encoding.ASCII.GetBytes("testing"));
}
catch (Exception exsoc)
{
listBox1.Items.Add("Problem sending data");
listBox1.Items.Add(exsoc.Message);
sock.Close();
return;
}
sock.Close();
}

Possibly a firewall error or the target IP+port is not enabled.

Hi all,
Thanks in anticipation.
I was working on something that reads a serialized (in vc++) file in c#. So I was using the unsafe sizeof to read or get the size of certain objects. I am providing some code snippet to make the problem comprehensive.
struct Node
{
public struct NodeConsumerSnID
{
Int32 m_nNoOfConsumers;
Int32 m_BranchAboveUniqueID;
}
////////// it is returning 8 Byte
public struct NodeConsumerSnID1
{
Int32 m_nNoOfConsumers;
Int16 m_BranchAboveUniqueID;// int16 or short
}
////////// it is returning 8 Byte
public struct NodeConsumerSnID2
{
Int16 m_nNoOfConsumers;// int16 or short
Int16 m_BranchAboveUniqueID;// int16 or short
}
////////// But it is returning 4 Byte
public struct NodeConsumerSnID3
{
Int16 m_nNoOfConsumers;// int16 or short
Int32 m_BranchAboveUniqueID;
}
////////// it is again returning 8 Byte
Now when I look through the output, sizeof(NodeConsumerSnID) returns 8 byte as expected. Also sizeof(NodeConsumerSnID2) returns 4 byte as expected. But unexpectedly, size0f(NodeConsumerSnID1) and sizeof(NodeConsumerSnID3) returns 8 bytes, whereas the expected value was 6 byte.
Can you please provide me some understanding on the same?
Regards,
Kangkan

The values are padded to be word aligned, I believe. I think there's an attribute you can set to turn this off. Sorry, I don't know what it is, offhand.

Thanks.
The problem is now solved by turning off the alignment.
