Which mobiles? Mobile phones have an OS and not all will support your .net code. If you are aiming at Windows based mobiles, look in to .Net compact framework. There is a plenty of documentation about that on MSDN. If you are aiming at Symbian based mobiles, you can make .net application again and deploy them using RedFiveLabs.
Try out some basic stuff to begin with through the tutorials available.
As far as making calls from PC is concerned, I don't see much relation of that with Mobile development.

Hello,
I've wrote UserControl where one of properties is collection. Item of collection is object of type GroupClass. Code below:
[Serializable]
public class GroupClass
{
private string pGrpupName;
private Control pGroupControl;
[Category("Group")]
[Description("Definition")]
public string GroupName
{
get { return pGrpupName; }
set { pGrpupName = value; }
}
[Category("Group")]
[Description("Definition")]
[Browsable(false)]
public Control GroupControl
{
get { return pGroupControl; }
set { pGroupControl = value; }
}
}
And after when I add item to collection also groupbox should show on UC. I've override some methods in my Collection. It works. But it doesn't when I try to remove item in designer. Groupbox is still there and method RemoveItem doesn't works 
public class WRListClass<T> : Collection<T>
{
public event EventHandler<ItemInsertedArgs<T>> BeforeItemInserted;
public event EventHandler<ItemRemovedArgs<T>> BeforeItemRemoved;
public event EventHandler<ItemSetArgs<T>> BeforeItemSet;
public event EventHandler<ItemInsertedArgs<T>> AfterItemInserted;
public event EventHandler<ItemRemovedArgs<T>> AfterItemRemoved;
public event EventHandler<ItemSetArgs<T>> AfterItemSet;
public event EventHandler ListChanged;
protected override void InsertItem(int index, T item)
{
EventHandler<ItemInsertedArgs<T>> beforehandler = BeforeItemInserted;
EventHandler<ItemInsertedArgs<T>> afterhandler = AfterItemInserted;
EventHandler handlerListChanged = ListChanged;
if (beforehandler != null)
{
beforehandler(this, new ItemInsertedArgs<T>(index, item));
}
base.InsertItem(index, item);
if (afterhandler != null)
{
afterhandler(this, new ItemInsertedArgs<T>(index, item));
}

I'm not going to bother reading that badly formatted code dump because:
1) because it is badly formatted
2) there is too much of it even if it were correctly formatted.
Solution:
1) cut out anything that is not relevant to the problem.
2) surround the remaining code with 'pre' tags and format it properly
You do not ask a question. What is it that you want to know?
Read this[^], before editing your original post. Pay particular attention to items 2, 4, 5 and 7.

I've made a small app that downloads an XML file every one minute from a server. I have to use a Socket for it as I must write the HTTP headers myself.
The program works fine until it doesn't. Every few minutes the XML that's being downloaded is somewhat corrupt. When I open it I can see the XML with all the normal data, except that in random places there are always 4 random characters that are being inserted. When I use a packet sniffer I can see that the data being received is fine and that the chars aren't in the end or beginning of a packet - just in random places.
This is the loop I'm using to read the XML file:
file = File.Create("C:\\info.xml");
bool isFirstPacket = true;
byte[] buffer = new byte[1024];
int bytesRead;
while (true)
{
bytesRead = stream.Read(buffer, 0, 1024);
if (bytesRead == 0)
continue;
if (isFirstPacket)
{
isFirstPacket = false;
int i = 0;
while (buffer[i] != 0x3c)
{
i++;
}
file.Write(buffer, i, bytesRead - i);
}
else if (buffer[bytesRead - 2] == 0x0d && buffer[bytesRead - 1] == 0x0a && buffer[bytesRead - 3] == 0x0a && buffer[bytesRead - 4] == 0x0d && buffer[bytesRead - 5] == 0x30)
{
file.Write(buffer, 0, bytesRead - 7);
file.Close();
break;
}
else
{
file.Write(buffer, 0, bytesRead);
}
}
file.Close();
Does anyone have a clue as to why this would happen? thanks.

I can't see anything that jumps out at me, apart from the possibility that you could be addressing a non-vaid location in the else if clause. If bytesRead is less than 5 at this point you could have a problem. Also in this clause you have file.Write(buffer, 0, bytesRead - 7); - should that be 7 or 5?
My only suggestion would be to run it through the debugger and try to see what's going on.
|
|

|

Thanks for the reply.
The else if works as it should, though you're right I should see if bytesRead is bigger than 5, the reason for the "-7" is some added spaces at the end of the XML.
As I go though the trace and look at the buffers I see these chars inserted in them, I get them through the NetworkStream.Read and still the network sniffer shows a "clear" packet. Odd.

Hello all of you,
I made a webservice and I can't get this to run via proxy.
the basic procedure on the client side looks like this:
MyWebservice service = new MyWebservice();
WebProxy iProxy = new WebProxy(_proxyAdress, true);
service.Proxy = iProxy;
...
if(service.LogOn(user, pass))
{
...
data = service.GetMyData();
now what happens is that the session variables are lost on the GetMyData() call
on the server side:
[WebMethod (EnableSession = true)]
public bool Logon(string s, string p)
{
...
Context.Session.Add ("LoggedIn", true);
...
return
}
[WebMethod (EnableSession = true)]
public SomeData GetMyData()
{
...
if(Context.Session ["LoggedIn"])
...
}
Whitout proxy it goes but with proxy dosen't. Please drop some tips if you have some. Thx.

Have you tried regenerating the proxy?

I suppose you need to attach CookieContainer to your web service instance using CookieContainer property of SoapHttpClientProtocol class.
service.CookieContainer=new System.Net.CookieContainer();
Read here more about Session and web methods.

Hi all,
Is there a way to open a named browser window from a windows application.
From ASP.NET i used javascript's "window.open(url,name)", is there some way i can achieve the same result from a windows application.
I tried some things with the System.Diagnostics.Process.Start(), but i don't know if it is possible to give the name for the new window in the parameters (if it is possible, i don't know how )..
Any ideas?
Thanks in advance.

do
{
iniText = iniStream.ReadLine();
if(String.Compare(iniText.Substring(0,1),("*")) == 0)
continue;
string [] dataItems = iniText.Split(new Char [] {','});
dataGridView1.Rows.Add(dataItems);
} while (iniText != null);
When stepping through the code, dataItems correctly contains each array of comma separated variables, but the datagrid control is not being populated with the Rows.Add method. What am I missing?
t.i.a
OK, I changed it to this
do
{
iniText = iniStream.ReadLine();
if (iniText == null)
continue;
if(String.Compare(iniText.Substring(0,1),("*")) == 0)
continue;
string [] dataItems = iniText.Split(new Char [] {','});
dataGridView1.Rows.Add(dataItems);
} while (iniText != null);
obviously I need to rethink my loop logic. But when i step through in Debug with F5 it populates the control properly, when I run without debugging, it is still empty. Why does that happen?

I agree your loop logic needs some work, but in both original form and the modified form below it works fine either debugged or run as release version.
Without seeing the rest of your code, I can only assume the difference is path related - is the file you are reading relative to the debug code folder and thus not available in the release version?
string[] lines = File.ReadAllLines(@"C:\XXTemp\new.txt");
foreach (string line in lines)
{
if (!line.StartsWith("*"))
{
dataGridView1.Rows.Add(line.Split(','));
}
}

Thanks. Of course, that is exactly what it was, I hadn't changed the file read section to allow the user to browse for an actual file location!
doh! thanks for the heads up

Hi,
I want to write some data to an excel sheet. If it is open, then write to the same excel sheet, if not open, then open the excel sheet and perform operations.
I dont know how to get control of the open excel sheet.
Here is my code:
//check if the worksheet is already open.
try
{
using (FileStream fs = File.Open(txtBx_worksheetPath.Text, FileMode.Open))
{
if(fs == null)
{
theWorkbook = ExcelObj.Workbooks.Open(txtBx_worksheetPath.Text, 0, false, 5,
System.Reflection.Missing.Value, System.Reflection.Missing.Value, false, Excel.XlPlatform.xlWindows,"\t", true, false, 0, true, false, System.Reflection.Missing.Value);
}
}
}
catch(Exception)
{
// activate excel sheet
// theWorkbook.Activate();
}
Now, if the file is already open, then it performs nothing.
I dont want to close the excel sheet and reopen it.
Please help me.
Thanks
Ananya

I am working with World of Warcraft and C#. In WOW there is no way to send data out to another app nor are you allowed to use Spy++ to read data from WOW. A though occurred to me to simply create an Addon that draws a series of colored boxes near the top of the screen away from any that would get in the way of the users use of WOW. These colored boxes would represent a value I would read in via C# screen area capture. My question is, is this the best way to go about something like this or is there a better way?
