Gee, thanks for all the information and for asking nicely! 
What is that number? If it's the number of milliseconds or ticks, from what epoch does it start? Whether it's UTC or not has no bearing, so long as you treat it as UTC.
If you read the documentation for the DateTime struct in the .NET Framework SDK, you'll see that the DateTime struct has an epoch of 1/1/0001 00:00:00. Without knowing the epoch of that number, it's impossible to help you, other than tell you to read about the well-documented DateTime and it's members, such as Parse and it's constructor, which takes a number as a long which represents the ticks (100 ns) since the epoch I mentioned.
If you need help, please provide more information.

Declare a state variable and set/reset it when you need. Use a timer if you have to.

Hello people, I have an Web Application and I need to get the Mac Address from client computer for security reasons. So I tried to do this by using Windows Control, but Windows Control isn't working when I call for System.Management objects like when I try to get the Mac Address. Explorer shows an alert about SecurityException. Anyone knows how to do this? another solution?
tks

You're trying to get the MAC address of a client on the server side of your ASP.NET application. The short answer is, you can't. Not because of the security restrictions either. Simply because when you try and do an ARP resolve on the IP address, you'll get the MAC address of the NIC on the side of the router that the server is on, not the client machine. There is no method of getting the MAC address of a NIC unless that NIC happens to be on the same physical subnet as the server.

Hi,
Im creating a basic port scanning program that using multi threads to scan ports to serve as a way for me to learn Sockets and Threadpooling, but when i build the program and try to scan one port i get an exception error.
System.Net.Sockets.SocketException: The requested name is valid and was found in the database, but it does not have the correct associated data being resolved for
at System.Net.Dns.GetHostByName(String hostName)
at System.Net.Dns.Resolve(String hostName)
at System.Net.Sockets.TcpClient.Connect(String hostname, Int32 port)
at PortScanner.frmportscanner.scanport(String host, Int32 port) in d:\csharp\ircbot\windowsapplication1\port scanner.cs:line 258
Any Suggestions?

Try using nslookup.exe in the command-prompt for the name you're trying to connect to and see what you get. The exception message indicates that the necessary data (perhaps an IPv4 address?) wasn't found.

I have written a service that grabs the files in a source directory on a remote server and ftp's to local directory. The service monitors the source directory of the server and collects the files as they come in. The Problem: Sometimes the files are physically present but the service recognizes and at the time of transfer it cannot get handle on them. I gut feeling is - the service tries to grab the file when it is in the process of being tranferred to the source directory. It loses the handle on the file and can never recover thereafter. Any suggestions !
Thanks / Vinayak

The service should maintain a list of files it has tried to copy. If the copy is successful the file can be removed from the list, if not an attempt can be made on the next cycle when it looks for files again.

Thanks Colin.
I have an ftp component that returns the list of files in the source directory as a dataset. But once the file is failed to be tranferred via the Service Component - I go for the next one tranfer it.
When the service makes the next attempt - is gets the failed file
in the list but fails to transfer saying that "the file can not be found".

Is the file physically there? Or in the first failed attempt did it remove the file? (Do you remove the files once they are transferred? If yes, could this be happening even if the file fails to transfer?)
Another, possible workaround is to build in a wait step before transferring the file. You see the new file for the first time, but you wait until the next cycle of the service before attempting to transfer it. As your FTP component returns the list of files as datasets, you could retain the previous dataset and compare it with the new dataset and transfer files that appear on both. BTW, how often do you check the directory for new files?
However, it would be better to find out why the files are failing to transfer and why on the second attempt the file is not found.
Does this help?

Yes, the file is physically there, yet - the service cannot transfer it!
It did not remove the file on the first attempt. However, if the transfer
is successful, I am removing the file from the remote server.
Your next point is a valid one, that is about removing the file despite its failure to tranfer. I have blocked the code in two try blocks.
In the first try block I try to tranfer the file and remove only if
it is successful. Else do not enter the remove block.
I liked your approach to the problem. Thanks / Vinayak

Can someone share some Interop C# Code on how to check a word document for Linked OLE Document (typically PPT) and then change it's OLELink Path to a new local directory?
Thank you in advance.

i need the user to select a value from a datagrid and put that values into a textbox?
|
|
|
|

Even handling the WM_PARENTNOTIFY message won't work (it will receive the WM_LBUTTONDOWN message, but you can just as easily handle DataGrid.CurrentCellChanged) because once the cell is in edit more, the hosted control is what is handling windows messages.
My recommendation is to just handle the DataGrid.CurrentCellChanged with a little logic to determine when the user is picking a cell (or may no additional logic is required).

yes it is a feature that i think many people have been asking for. the problem is i need the change to be immediate and the cellchanged is one step too late. I settled for the mouse down event it works a treat to increment the value in a textbox i am now working on an event to decrease the value and hopefully trap the right mouse button and use that to decrease the value. growing in confidence by the day!!!

Hi,
I'm just asking your opinion for a design question. I'd like to present you some key facts about a quite complex application I just start working on. Important for me is the simplicity of the design. Performance or Complexity is not an issue. I just want to be able to understand the code even if a year has been going into the country.
1. The application is a based on a SQLDB. Some of the clients of this application are webbased and some are winforms applications. I'd like both of the client-types access something like a (or multiple) core.dll('s) which implement(s) all the logic and data-access stuff.
2. The application maintains users, usergroups and permissions. That is, each user belongs to a group and each group has certain permissions in terms of what it can do (what commands it can execute). A command might be something like "Create a new Project", "Print this" or "Enumerate this collection".
4. Commands, which are not available to the user (because he hasn't got sufficient privileges) should not be shown in the GUI (that is, if the User is not allowed to "Print this", he shouldn't have a menu-item in his Winforms GUI saying "Print this".
What makes me a headache at the moment is the question of how to design my classes. I'm dealing here with a lot of collections (Customers/Customer/Contacts/Contact, etc.) Basically i'd like to have a nice, clean and understandable object hierarchy.
If you feel you'd like to discuss this question (might be helpful to others as well) but you need further information, please let me know.
Thanks for reading,
Matthias

1, 2 and 4 seem reasonable. (Is 3 AWOL?)
What do you mean by a "nice, clean and understandable object heirarchy"? Do you mean the way the classes relate to one another, the namespace that a class might sit in or what?

I don't know what AWOL is, but it has just gone down the road...

I don't mean the namespaces, these classes might sit in. It's rather the way, classes relate to one another, eg.:
Say we have a root class (top-level), called DB_App, this class might then have a property allowing access to the Projects collection, which in turn might be used to access a Project instance which in turn has a property called ProjectServices (collection), and so on. Is this reasonable?

AWOL = Absent WithOut Leave
Yes, your suggestion seems reasonable. But, I find that object relations often closely map to the relationships in the database, so if your data model is heirarchical then it would follow that so will your class model be.
