I'm not too fussed about the loss of precision, i can deal with the nearest second. But thanks for the input. Is there any easy way to round a date? I've always created new dates and copied the relevant values over before.

One of the earlier replies from Luc shows you how to do this. Yes, you have to create a new DateTime (it is immutable so once you've created one you can't change it) but there is an easy way to do it using AddMilliseconds. Sounds like a good candidate for an extension method if you're at the right version of .NET. Otherwise, a good old fashioned DateUtils class would do.

You'll be waiting a long time if you don't make a request.
I suppose I could make a TimespanTruncate.

Yes. A quick Google Search can get you more guidance on it. Also, as the other poster advised you, refrain from publishing your private info like email address and telephone numbers on forums/webpages.

Hi all
i am doing export to excel operation using below code.
public void ExcelExport(System.Data.DataTable tblExportData, string TempFilePath,string userInfo,bool headerStatus)
{
try
{
Microsoft.Office.Interop.Excel.Application excelApp = new Microsoft.Office.Interop.Excel.Application();
excelApp.Workbooks.Open(TempFilePath, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
//Writing Header in Excel
if (headerStatus == true)
{
for (int i = 0; i < tblExportData.Columns.Count; i++)
{
excelApp.Cells[7, i + 1] = tblExportData.Columns[i].ColumnName;
}
}
//Writing Data in Excel
for (int i = 1; i <= tblExportData.Rows.Count; i++)
{
for (int j = 0; j < tblExportData.Columns.Count; j++)
{
string colName = tblExportData.Columns[j].ColumnName;
excelApp.Cells[i + 7, j+1] = tblExportData.Rows[i-1][colName];
}
}
//Create a worksheet object
Microsoft.Office.Interop.Excel.Sheets sheets = excelApp.Worksheets;
//from the collection of worksheet select one worksheet
Microsoft.Office.Interop.Excel.Worksheet mySheet = (Microsoft.Office.Interop.Excel.Worksheet)sheets.get_Item(1);
//select the cell in the worksheet
Microsoft.Office.Interop.Excel.Range myCell1 = (Microsoft.Office.Interop.Excel.Range)mySheet.get_Range("A6", "A6");
myCell1.Value2 = userInfo;
myCell1.Font.Color = System.Drawing.Color.Black.ToArgb();
excelApp.Visible = true;
}
catch (Exception ex)
{
}
}
it's working fine in local. but when i deployed this on server(e.g.relience server) then it stops to work. i mean exporting to excel not working. Even it's not generating any error and page is redirecting also. can any one help me please.

Hi all,

When i click a link button a query should be executed to take the corresponding path,then with that path the file should be opened.
i tried like this..
Private Sub Linkbutton6_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Linkbutton6.Click
Dim str As String
Dim command As String = "SELECT FILENAME FROM S_TR_BUILDDATA A WHERE 1= (SELECT COUNT(DISTINCT B.DATEOFBUILD ) FROM
S_TR_BUILDDATA B WHERE A.DATEOFBUILD <=B.DATEOFBUILD) "
Dim DFmenu As DataSet = Me.ExecuteSql(command)
str = DFmenu.Tables(0).Rows(0).Item(0)
System.Diagnostics.Process.Start(str)
' Response.Redirect(str)
End Sub
its getting filled in dataset..
but the file is not opening..
what shall i do???
thanks n regards,

Is that a question and then answer? Or is it something else. You might want to try and express that in a different way.

In datagridview when press any key then from that column select the Cell strats with that latter. How can i do tht the Grid is already bound.
|
|
|
|

Something like the following should get you started toward a solution.
private void yourDataGridView_KeyPress(object sender, KeyPressEventArgs e)
{
foreach (DataGridViewColumn column in yourDataGridView.Columns)
{
if (column.HeaderText.StartsWith(e.KeyChar.ToString()))
{
column.Selected = true;
break;
}
}
}
You will also need to pay attention to the EditMode property of the DataGridView, to stop the grid going into an edit state when the key is pressed. Read the documentation for EditMode for the options.

Hello,
When I call SDI winodw form from modal window and then again modal window form, from SDI window and when i close the last form the focus goes to first modal window istead of going to SDI window ... Can anybody tell me Why it happens ?
First window (Form1) ---> Call modal window on button click (Form2 f2=new Form2(); f2.showDialog();)
---> from Form2, Call SDI window (Form3 f3=new Form3(); f3.show()) -----> From Form3 call another modal window (Form4 f4=new Form4(); f4.showDialog();
When I close the fourth form the focus goes to Form2 instead of Form3 why It happens ? And it happens in case of compact framework C# ....
Regards

I am trying to create a licencing class library whereby an attribute is added to the AssemblyInfo.cs and when the assembly is loaded (not using Assembly.Load) validation is performed to see if the assembly has the attribute and then checks a licence key to ensure it can be run.
I thought the AppDomain.AssemblyLoad event might work, but after testing I am now assuming that only fires when you use Assembly.Load. I am a bit stuck as to whether this can be achieved and how.
I will eventually like to be able to do this validation at class level so that if someone tries instantiating an instance of the class, a licence is checked for access. One method is to use a proxy type mechanism like the Enterprise Library Injection Policy Application block, but ideally I would like it to fire is someone does the usual Foo f = new Foo(). The class level validation would ideally not have to be duplicated in every class (e.g. added to the constructors).
Any ideas on how to do this?

Hi,
I don't know about assembly events. However IMO you might be able to get what you want by adding code to the static constructor of the class you want to protect; in order to protect several classes, let their static constructors access the one class that takes care of licensing.

Thanks Luc.
I agree that I think my only option is going to be to add some code to the constructors of the classes I want to protect. I think I may also be able to use some interface that defines a method that adds a class type to some licence manager class.
Well off I go again for some more experimentation.

It it possible/practical to have an application which will accept an incoming TCP connections, communicate enough to identify the remote device, and then hand the socket to either a newly-launched executable or one which is already running? What would be the best way of doing that?
I'd like to have a service that will accept connections on a particular registered TCP port, which would ask the connecting device to identify itself and then use its returned identity to select one of a number of programs to access it. If someone is running an interactive application to handle the connecting devices, the connections should be routed to that application.
One approach would be to have the application allocate a new temporary port and notify the service that it has done so; the service could then act as a proxy exchanging all information between the remote device and the 'real' application. That would add extra overhead, however; it would seem more efficient for the service to hand off the connection to the application so the application would handle the incoming data directly.
Is there any nice way to accomplish this in .net?
|

Thank you. That looks very useful, at least in the case of handing off the socket to an already-open application. What would be the preferred method of handing off a socket to an application which isn't yet launched (assuming .net 2.0)? I've not used named pipes, since the managed API's for those FWIU only appeared in .net 3.5, though if they're easy to use from .net that might be handy. Otherwise I could have the newly-launched application "telnet" into the service port, say "hey I'm here, this is my process ID, and I'd like a socket if you have one"; the service could then give the socket to the new application.
One of my design goals is to minimize the possibility of the service imposing an excessive burden on the system even if things go wrong (e.g. a connection comes in and the service launches the application, but the application never gets around to dealing with the port). I don't particularly like the idea of the service having to hold the connection until the application gets around to asking for it, but it wouldn't be too horrible. I could probably have a 30-second timeout or something on it (if the application hasn't picked up the socket by then, the remote device that's "telnet"ing in will likely give up anyway), but that adds some complexity.
BTW, what's the best style for using the Select function? Creating three lists from scratch each time I want to poll for data, and then using a dictionary to map the connections in each list back to my own connection-info objects seems rather klunky.

For interprocess communication between processes on that same machine,
I'd just use .NET remoting. The IpcChannel/IpcServerChannel/IpcClientChannel
classes are efficient, and probably use named pipes for their transport.

I don't know - I never use it, and I personally think it's kind of dated.
I much prefer I/O completion ports or the asynchronous APIs in .NET. Thread pool
stuff is much more efficient.
I prefer a class that represents/wraps a connection (e.g. a socket) and handles
its own asynchronous I/O.
