Hi,
I'm writing a windows service, and I need the service to save data in the currently logged in users home directory (my documents). Is there a way to get the path for it?
I know Environment.GetFolderPath(Environment.SpecialFolder.Personal), but it gets the home directory of the user who runs the service (in my case the local system account).
Thanks in advance!
Greets,
Daniel

Do you already know anything about the currently logged in user? If so, you might want to try impersonating that user and then trying the command you just described. (Never done it, but read about it a few times.)

I doubt there is a managed method for doing this.
Under C# this will be cumbersome (lots of Interop calls), maybe the best way is MC++, but the only way I know for a service to interact with the logged in user(s) is by calling OpenWindowStation. In your case, you should call the GetUserObjectInformation to get the user SID, then go to the registry and recover the path of the user's home directory.
Not for those who fear API calls.

Hi,
I'am searching a hint or a good example for following problem :
I have zipcodes and towns. One zipcode can be attached too 1 or more towns
ex. 1000 Town1
1000 Town2
1001 Town3
1002 Town4
...
In my form a combobox is not efficient (there are too many zipcodes and towns). So, I need another button that opens a dialogbox. This dialogbox show all records (zipcode - town) and when I double-click on a record I come-back too my form, where the choosen zipcode is in one textbox and the town in an other textbox.
Thanks in advance for the hints or the examples.

This type of thing is done fairly often. I'd suggest browsing through the C# projects already on this site until you find one that opens a sub-dialog and then retrieves the values selected. (In fact, the SaveFileDialog and OpenFileDialog boxes that are part of the .NET framework do the same type of job.)

In order to be able to switch the Tracing level on our application (which is a service) without stopping it, I implemented a Trace wrapper that watches fot the app.exe.config file to be noticed on any change on it (NotifyFilters.LastWrite). The wrapper has other utilities too and is compiled in a class library.
I wrote a small exec that tests the wrapper. When I start the program in debug mode (F5), and I change the config file using a file editor, the program is noticed (the FileSystemWatcher.Changed event is raised). But when I start the program in non-debug mode (Ctrl-F5), and I change the config file, the program is NOT notified of the change.
Do anybody have any clue of what is happening?

I have a big problem when reporting from MS SQL database!
I created a report which should report from MS SQL db table T. When I try to show report it always prompts me to connect to database (ask me to enter username, password, server, database). It does that even if I programmatically set
CrystalDecisions.Shared.TableLogOnInfo logOn =
new CrystalDecisions.Shared.TableLogOnInfo();
logOn.ConnectionInfo.DatabaseName = "dbName";
logOn.ConnectionInfo.Password = "password";
logOn.ConnectionInfo.ServerName = "serverName";
logOn.ConnectionInfo.UserID = "userName";
logOn.TableName = "TableName";
Report.Database.Tables["TableName"].ApplyLogOnInfo(logOn);
Why???? What am I doing wrong?
thanx

i have a client / server application, i'm using Sockets, and BinaryReader, BinaryWriter.
the application supports multiclient, so i'm using multithreading.....a thread for each client
i have a problem in disconnecting both the server, and the clients...
i do not know in what sequence should i close the thread, the sockets, and the reader/writer !!!!
for both the server and the client
plzzzzzzzzzzz can anyone help me !!!
P.S: this application is my graduation project, which will
be discussed in two days !!!!!!!!!

Socket connections can have either connection closed first. The documentation describes how to close an open socket. (Depending upon how a socket is opened, closing a reader or writer may close the underlying socket. Just use some try/catch handlers with Trace.WriteLine(err.ToString()) to catch and understand any errors with what you try.)

Yes, you can do it in some ways, the easiest one is customizing the toolbox and adding from the COM Components tab, the "Microsoft Web Browser" (\system32\shdocvw.dll), then you just need to drag it to your form. To get more information about how to use it check this link

My mdi app has a navigation screen on the left hand side with link labels that when clicked will decide which form will get displayed on the right hand side. I want to pass a parameter to the eventhandler whenever a link label is clicked but I don't know how to do this. Please, can any one show me how?
So if I have the code below, how can I pass formName to the OnClick method where the formName depends on the link label they click.
public class Home
{
private void InitializeComponenet()
{
button1.Click += new System.EventHandler(OnClick);
}
private void OnClick(string formName)
{
eventHandler(formName)
}
}

Look at delegates and EventArgs. That will show you how to pass parameters on events.
If you have a main MDI window which creates your MDI child windows and the navigation is a MDI child window that you can only have one of (I am thinking of a left side tab strip type of navigation while the right side hosts all the MDI windows). If this is the case, your main window will have the reference to your navigation window (since it creates it). You could have your main window pass a reference to your navigation window to your MDI children windows. They would then be able to pass the event information directly back to the navigation window would having to raise events.
MainForm
NavigationWindow navWindow = new NavigationWindow();
...
// Some event happens and child window is bring created
MyReportChildWindow child = new MyReportChildWindow(navWindow);
NavWindow
public void OnSpecialClient(string formName)
{
// Do something
}
MyReportChildWindow
private NavigationWindow navWindow = null;
public MyReportChildWindow(NavigationWindow navWindow)
{
this.navWindow = navWindow
}
public OnClicked(object Sender, EventArgs e)
{
navWindow.OnSpecialClient(this.Text);
}
There are other ways to handle this situation. With delegates you will have to have either the Nav window or the Child window know each other in order to register the delegate unless you had the main window set the delegate for the child window when it was created. Would be easier with the above than that.
Another possiblity, is if there will only ever be one Navigation window, you can have it have a static member that you can call from all your child windows. That way you do no thave to pass anything, you could just call NavigationWindow.OnSpecialClient(this.Text) when the event occured. This kind of make the NavigationWindow method global to your application.

Thanks for your reply, but I am still not clear on how to implement what I am seeking. I know I have to create a class that derives from the System.EventArgs base class, but I am not sure how creating this class ties in with everything else. For example, where do I instaniate this class, how does that relate to onclick and the type the method takes. Any help is appreciated.

Hi there,
I have a file called exmple.aspx created in a notepad and it ran well in a IE web browser and i enjoyed the result. But as i want to run it in the visulastudio IDE, i created a project, SampleProject and right click on the project added a webform and named it as exmple.aspx. copied the code from the original file(notedpad) and saved it, tried to run the file by right clicking it and choosing the option 'view in browser' but unfortunately it displayed the following error .
Server Error in '/SampleProject' Application.

Hi friends!
Would someone please tell me what may be the reason for somebody to choose C# instead of VC++ to create windows applications? I think C# is only proper for WEB applications that don't need realtime capabilities.
Does have C# any capability that VC++ doesn't have it?
Your comments will be greatly appreciated

Unless you meant Managed C++ applications instead of VC++, your question is a bit off. Wouldn't it be more like "Why would you use .NET to create Windows applications instead of the Windows API?"
The first question is, what kind of market do you wish your application to target? Does your product plan to access information on the net? Is your product client/server or n-tier? Will your program target Windows 95? Are you interested is cross platform development?
These are just a few of the questions to help decide which tool to use. With .NET you can make robust applications that are extreamly scalable with easy modular design that can share code between a web application or windows application without recoding. With .NET remoting, you can distribute your application workload over multiple computers or over the Internet without changing your code. You can even run modules in your application in multiple sections (AppDomains) to protect modules from crashing and taking down the others.
Unfortunantly, Microsoft has done a loosy job at marketing .NET. Most people think of .NET as a web or internet platform. There is much more to it, and I cannot describe all that here.
The .NET frameworks provides the programmer with object oriented platform. There are over 8,000 classes in the .NET frameworks and they can be accessed from either a web application or a WinForm (Windows) application.
For .NET you can use any of the .NET languages included Managed C++ if the speed is required. C# just happens to be one of the languages which happens to have a lot of the flavor of C++ without all the hassles. I have been a C++ programmer since Windows 3.0 and find it very natural to use C# now (having been working full time with it for the last seven months) and hate to use C++ anymore. There are a lot of gotchas and things you just have to eat and not worry about, but the end result comes a lot easier and a lot less debugging.
For me, C# and .NET has made me move more object oriented than I ever. It is so easy to break a program up into modules that can easily be remoted, this I would not have thought of usually with C++. I personally have just about kissed COM/DCOM off. Don't need it anymore. While there are some time legacy programs you have to communicate with, if all the code is new and you can ran everyone on .NET, why bother. Although some people that have invested in lots of COM modules might disagree 
Another major point for me, is the movement to run .NET and C# on other platforms. Mono project has been working on a compatible WinForm (Windows applications) and WebForm to run on Linux. There are some cross platform applications starting to rise even though they do not have it 100% complete. It seems funny to design Linux GUI applications and be using C#. I expect to see much more this direction as long as Microsoft does not put down their foot.
Those are just a few of the reasons I use .NET and usually do not bother with other technologies. C# is my new language of choice and personally, I could care less if I ever see one line of C++ code again.
