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?

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.

You'll get lots of spam this way, but no replies.

Why would you want to ? You're checking the login, not setting it, right ?
How new are you to C# ? Do you know another language ? Did you write the database ? How do you do other database access in your code ?

You're not executing your query - try cmd.ExecuteNonQuery(); before you close the connection. You might find you also need a cmd.Prepare(); after setting your parameters.
It's also good practice to have your open statement in a try block and your close in a finally block.
Instead of using 3 lines for each of your parameters you can create parameters like this
cmd.Parameters.Add("@value", SqlDbType.VarChar, 50).Value = textBox1.Text;
Hope this helps.

Well, first use try/catch methods if something doesn't work as you wish, it helps you debugging the application a lot.
I think you should use something like this :
try
{
con.Open();
SqlCommand cmd = new SqlCommand("INSERT INTO login(userid,password) VALUES('"+textBox1.Text+"','"+textBox1.Text+"')");
cmd.ExecuteNonQuery();
}
catch (System.Exception ex)
{
MessageBox.Show(ex.ToString());
}
You can see you aren't using the ExecuteNonQuery function ... maybe that's the problem
