Hello,
Is there anybody out there who could give me a hint how i can realize async callbacks from a server application to all connected clients. I tryed several ways solutions based on the articles on this website, but they didn't work fine.
In the scope of my apllication there is the need to tell all clients that something happend. So the client connects via .NET Remoting over TCP to some implemented and marshaled well-known interface. This works pretty fine and easy. So what i need now is that the client could take some real events from the server.
So if there are any ideas and any help i would be very thankful about getting told about it.
Thanks
Frank Friebe

Simple events should work. Add the event to the server interface, subscribe to it from your clients and it should work. You might get some security exceptions, see this[^] post for more details.

button(Set Position)
now user can alter the position of names and when click on button, all records should be updated with new position values...
for this I want to make two input arrays like:
<input type='hidden' name='id[]' value='id from database'>

Assuming that you are using the "codebehind" coding style (which is the recommended way) - your CS file linked to your ASPX page will have a class in which the textboxes representing positions (visible ones) as well as the textboxes representing the id-s (invisible ones) should have corresponding "protected" members (of type TextBox). If you do not see any, that may be because you are using the "non-ASP.NET" control "input". Instead, if you use the ASP.NET control TextBox (drag and drop them on your aspx form using the toolbar), the corresponding CS class objects will get auto generated.
That said, there is still way to continue using the HTML "input" controls and represent them in your CS file with corresonding TextBox members - in that case you have to declare the TextBox objects in your CS file by yourself.
All this because you need those CS objects to do what you are trying to do. Once you have them - then in Page_Start, if PostBack is false (first time) - just set the texts of the textboxes with the database values, and if PostBack is true (after Set Position button is clicked) - pick them up and execute your update query. That's it!
And yes, this is indeed cross posting.

hi
i want to use Progressbar in My Winform App.please help me that how to use it in my Winform app ?
(please give an example like copying file or ... only in winform app (not web base apps or web service or ...))
regards ...

msdn.microsoft.com will show you how to use a progress bar. The key point is, you can't use one for a process that you call atomically ( i.e. you can't call File.Copy and show a progress bar while that one statement runs, at least not accurately ) In either case, you need to do your action in a worker thread so that you UI is updated properly.

Hi all,
I new to C# and I are looking to write an app that will enumerate a range of IP addresses on a network IE: 192.168.1.1 to 192.168.1.254. I am having trouble with converting an IP address string to int32 and vice versa as the string is in a dotted decimal notation IE: 192.168.1.1
Any suggestions?
Many thanks in advance

You can call the split method on the string to get an array of strings, one for each number. Then convert.ToInt16 will work fine.

hi guys,
how can i get the window name of a program (e.g. MS Word) programatically? im using c#, and im using this in my program that ends/terminates an application based on data returned by some queries from a database.
i have no problems if i start a fresh instance of MS Word since i can have the window name hardcoded in my program (the default window name is "Document1 - Microsoft Word"), thus i can still close that application using my code. the problem is that when i open an existing file (thus the window name is dependent on the filename specified by the user), now when this happens, i cannot close the application since i cant get the window name dynamically. pls help.. tnx

Hi,
First get the active word application and iterate thru the Documents.
private void IterateWordDocs()
{
//Iterate docs
foreach (Microsoft.Office.Interop.Word.Document doc in WordApp.Documents)
{
//Your doc name
doc.Name == "YourDocName"
}
}
Regards
Gokul

You can use Process.GetProcesses to get the Process instances associated with MS Word and then use MainWindowTitle[^] to get the window titles.

How can I debug attributes ?
I wrote a custom attribute for a control and I put a breakpoint in it but it does not stop in it.
the problem with the code is that it is invoked in design time (at design time of the project using my control).
is there a way to debug it ?

Dear all,
I need to know given a datatable wether it is sorted or not.
I need this to reverse the sorting (i.e. if it is sorted Asc make it Desc and vise verca)

When you populate it use ORDER BY column ASC then store a boolean value with the datatable, e.g.
bool isSortedAsc = true; Then, if you need to flip the order you will know which order it is currently in by the Boolean flag.

If you want to call a method from .Net assebmly you dont have to use DllImport, you can juse use reflection (see System.Reflection namce space). Dllimport mainly used to interface with native dlls not .Net assebmly. For example if you want to open a file and get the file handle you may write something like
[DllImport("kernel32",CharSet=CharSet.Unicode,SetLastError=true)]
static extern unsafe int CreateFile(
string filename,
uint desiredAccess,
uint shareMode,
uint attributes,
uint creationDisposition,
uint flagsAndAttributes,
uint templateFile);
in your .Net code, and call this as like any other .Net methods.
