Thank you sir... It would have been much easier if MS read the AssemblyInfo file for the project (but maybe is in the next release)

Using a web form and making a connection using a socket connection I can do.
The problem is executing a command on the UNIX box once I am connected.
I need ANY and ALL help
|

Aren't you using a client-server architecture? I would assume that you just want to code the server in C/C++ on linux and the client in C#. Your communication protocols are all that really need to be the same. The server would just execute a certain unix command when it reads a certain keyword that the client sends.

I get connected using the socket. Now I need to execute some unix command and I do not know how to proceed once I am connected.
Here is a sample of my code: (The Process object code is converted from VB.NET)
Socket tempSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
try
{
tempSocket.Connect(endpoint);
if(tempSocket.Connected)
{
this.txtstream.Text = "connected";
try
{
string strResults = "";
ProcessStartInfo psCmd = new ProcessStartInfo();
//Setup New Process Info
psCmd.FileName = Environ("ComSpec");
psCmd.RedirectStandardInput = False;
psCmd.RedirectStandardOutput = True;
psCmd.Arguments = "/c ls"; psCmd.UseShellExecute = False;
Process procCmd = Process.Start(psCmd);
//Read in Results & Write to current cmd session
strResults = procCmd.StandardOUtput.ReadToEnd();
this.txtip.Text = strResults;
procCmd.WaitForExit;
}
catch
{
this.txtip.Text = "no directory list";
}
}
}

Hi, I want to override an OnClick event on a datagrid and display a dropdown menu. Here's the code:
private void OnClick(object sender, System.EventArgs e)
{
int row = dgReport.CurrentCell.RowNumber;
int col = dgReport.CurrentCell.ColumnNumber;
//Question: How can I retrieve:
//(1) selected Cell width
//(2) selected Cell height
//(3) selected cell position
//I don't think I found anything from DataGrid properties. Anyway, once I have cell width, cell height, and cell position, I can dynamically create a dropdown list at the specified location and size.
}
Thanks.

hi,
here is the one way you could do this, but there could be an easier way.
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemwindowsformsdatagridclassgetcellboundstopic.asp
the method is GetCellBounds, which returns the Rectangle object which has width, height, X and Y properties.

In VB6 I used the following code with no problems:
xlsheet.HPageBreaks.Add Before:=xlsheet.Rows(rowcnt)
In C# I don't know what parameter I'm supposed to pass to the HPageBreaks.Add method. I keep getting the error:
"Object must be a normal type and not an array"
I've tried passing it an excel range, and the row number with no success.

Hi all, hope you can help on this one.
I have a C++ struct like this below:
struct OTHERSTRUCT Thing[MAX_NO] = {
{1, "x"},
{2, "xx"},
};
where OTHERSTRUCT is:
struct OTHERSTRUCT
{
int Num;
CString Desc;
};
My question is how do i replicate this in C#? the only way i have so far got this to work is shown below:
public struct tagLINE
{
public tagLINE(int ACode, string ADesc)
{
Code = ACode;
Desc = ADesc;
}
int Code;
string Desc;
};
And creating an instance of it like this:
public tagLINE[] A = new tagLINE[3] {new tagLINE(0, "0"),
new tagLINE(1, "1"),
new tagLINE(2, "2")};
Do i really have do all this "new"ing? Any feedback would be
great.

So, normally a structure is not new'd when instanciated, except when it's going into an array? This means that the array can only hold reference types, right? Are the value types actually boxed as they're added to the array?
I appreciate you sharing your knowledge on this stuff or pointing me somewhere that explains it better.

Alvaro
Can I ask you a question?

I was under the impression that new was optional for structs. Try getting rid of the constructor altogether and assigning directly to the structures values. Don't see why it wouldn't work.

I'm working on an application for a school. The web based application needs to give teachers (some teachers have been assigned organizational units) the ability to edit certain group policies. How would I go about getting an object for the "Proxy settings" policy. it seems like the api function GetGPOList might do it, but I'm somewhat lost.

Hi all,
I have a serializable class 'A' which contains a ArrayList. I create a new instance of class 'A' and add a new instance of Serializable class 'B' to the arraylist.
Now when I try to Serialize class 'A' with BinaryFormatter it just dies..no errors, no crashing.I've marked the statements in vs.net and it just stops when it hits the line that serializes it. Im only attempting to serialize class 'A' thinking that it should serialize all classes its linking to automatically? is this correct?
I have no idea why this is happening and have been struggling with it for a few days now, has anybody got any ideas?
Thanks,
Matt.

For me it works.
I have
[Serializable]
class A
{
B[] arrayOfB;
}
[Serializable]
class B
{
}
Perhaps it's because you haven't set the Serializable attributes to all? Or because you are using an arrayList? Try with a simple array to check
|

Things to check
You will need [Serializable] attribute on each class (should throw an exception, not hang), if it still doesnt serialize, the objects could be far to complicated to serialize, I have had a problem using the binrary formatter on certain complicated objects, it looses data and generally is unstable (I think this was in release 1.0, I Havent tried in 1.1).
Theres a handy undocumented class called LosFormatter, i think its in the System.Web namespace, its a very agressive serialization class which can serialize more data types than the binary formatter. Use it in exactly the same way you would use the BinaryFormatter class.
FYI: LosFormatter is what is used to generate the ViewState field in an ASP.NET application. I cant guarentee it will solve all your problems tho

That led me to add extra logging through the process, and I found that it dies when i add to the collection, rather then when it serializes.. turned out to be that I didn't initialize the arraylist d'oh!
It seems to always be something simple that I totally overlook.
Oh well, thanks for the reply (:

I want to Drag files from a TreeView from my application into Windows Explorer. I know hw to get Drag Drop data from windows Explorer but I don't know how to do it from my application to explorer.

Start the drag operation with:
treeview.DoDragDrop(new DataObject(DataFormats.FileDrop,files),DragDropEffects.All);

Thanks for reply.
The problem is here what is the second parammeter of DataObject should be. I think it should be kind of stream.

An array of file names, maybe?

I have a class that contains two variables.
Class Toto
{
public int Var1;
public string Var2;
}
I serialize this class through a binary formatter.
Everything runs fine.
Now, I want to add a new var to my class
Class Toto
{
public int Var1;
public string Var2;
public string Var3;
}
If I try to deserialize my previously saved bin, I got an error.
Is there a way to deserialize an "old version" of the class, reading only the fields that existed at the time of serialization, and leaving the new fields empty?

Hi guys,
I am trying to create TCP Listener windows services using C# to listen to a local TCP port continuously.
I have written a windows console application which does the job properly but when I convert it to windows services it did not work, as you know definitely I can not use infinity loop on the OnStart method but I want the services to keep listen to synchronous connection by a client and send response when data received.
The senior as following:
I want to listen to a port which I will receive a string 200 characters from a client then send response as acknowledgement.
Your response is highly appreciated.
Regards,
