Is there something similar to app.path in C# for the path of an application's folders and files.

If you need the current directory, try Environment.CurrentDirectory
If you want generic Application Data directory,
try Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData

If it's an SWF program, you can also try Application.ExecutablePath.

you can also try this :
string str;
string s;
str = Application.UserAppDataPath.ToString();
s = str.Substring(0,3);
MessageBox.Show(s);
that would return in this exapmle "C:\" , because i was testing it from a drive called C
switch(twinsOnWay)
{
case ("twins on the way"):
MessageBox.Show("for mr and mrs dynamic","twins on the way");
break;

Hi, all:
When I click on the menu item "Save", right after I edit the text in my Textbox control, in my WinForm, it does not cause validation of the TextBox control. Is there any way to force validation of the control. BTW, if I click on the x to close the form or any other controls on the form, it does cause validation. Any help is appreciated. Thanks in advance.

DO something like the following, it worked for the same problem:
if (panel1.Controls[0].DataBindings.Count > 0)
panel1.Controls[0].DataBindings[0].BindingManagerBase.EndCurrentEdit();

We want to use the auto-documentation for our C# project. Since the output of the documentation is XML, I believe that I need an xsl or something like that (sorry, I'm not proficient in XML) to transform the file to whatever I want (html, ...).
Is there any example of such a thing, so I could start from there? It would be nice to add one that produces MSDN-like HTML.

I hate to ruin the fun you'd have with countless hours of XSL and CSS coding to achieve this result, but someone already did it

Hi,
In MFC I will often create a UI thread and use it as a worker. I do this because I find the message queue that comes with the UI thread to be very handy for recieving messages in order. When it gets a message it does some work. I also use it to aviod race conditions, i.e. I can have many threads sending messages to the queue and MFC/Windows handles the "Reader Writer" issues of the queue.
What is the equivilant of this in C#? Is there a ready made thread with a message queue where all I would have to do is wait (sleep) until a message arrives?
Thanks.

I don't know if there is a .NET Framework way of doing it, but you could use the ExitWindowsEx[^] API.

Hmmm... what's a signature?

You can also do it with WMI Script
Set colOperatingSystems = GetObject("winmgmts:{(Shutdown)}").ExecQuery _
("Select * from Win32_OperatingSystem")
For Each ObjOperatingSystem In colOperatingSystems
ObjOperatingSystem.Win32Shutdown(1)
Next
Save this as .vbs file and run it.
you can also reboot with this script.
'Reboot computer script.
strComputer = "."
Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate,(ShutDown)}!\\" & _
strComputer & "\root\cimv2")
Set colOperatingSystems = objWMIService.ExecQuery("Select * From Win32_OperatingSystem")
For Each objOperatingSystem In colOperatingSystems
objOperatingSystem.Reboot()
Next

Does anyone know how to pass an array of strings using unmanaged code? I'm attempting to use unmanaged code to execute an external application with arguments, for example:
c:\matlab\bin\matlab.exe arg1 arg2
The code works fine when arg1 is substitued for a single space character, and matlab executes as if no arguments were passed in. However when arg1 and arg2 are string objects (containing meaningful arguments) in an array of strings, an exception is raised, stating:
"Object reference not set to an instance of an object"
The code which makes the call to the unmanaged code is basically:
public class Win32Wrapper
{
[DllImport("PFA_Win32.dll", EntryPoint="RunExternalApplication", CharSet=CharSet.Ansi)]
private static extern int RunExternalApplication(String application, String[] arguments);
public int RunApplication(String application, String[] arguments)
{
int result = RunExternalApplication(application, arguments);
return result;
}
}
The unmanaged code, written in C++, looks something like:
extern "C" PFA_WIN32_API int __stdcall RunExternalApplication(const char *app, const char *const *argv)
{
return _spawnv(_P_NOWAIT, app, argv);
}
I'd be most appreciative if anyone has done anything similar to this, or can see any flaws in the code.
Thanks
Ash

I read this on RSS Bandit (GotDotNet) forum.[^]
Question: still does not have any idea where the huge memory use really take place. Readed somewhere, that usage of IE as an embedded control needs additional 12-15MB, but where is the other 70% used? Anyone had any idea? If I build a simple form with only one button it needs at least 15MB RAM, why is it so havy?
I am just curious, anybody know the answer?

Yes: people doesn't know the difference between the used memory and the working set size of a software.
What task manager is showing you is roughly the working set size. It's a very hard and time consuming thing to determine the real memory use of a program, specially if it uses GC.
Each thread on a .NET application receives a 1MB virtual stack. Notice the "virtual" word, it means that it can use up to 1MB of stack space, but it could be (and probably is) using even under 1Kb of this space. The memory is only drawn for Windows when is needed.
So, a simple .NET application may have a few threads for housekeeping, like GC, so, even the simplest .NET application can show a large number on Task Manager.
Most GC preallocates some memory for its use, and the .NET Fx's one is no exception.

Off topic
Daniel, I read somewhere in the net about a memory leak caused by processor intensive applications.
For ex. in an app, if there are some processor intensive operations along with some non-trivial memory allocations, tehre is a chance that because of the processor intesive nature, the GC might not have a chance to deallocate, 'cause GC runs as a low priority thread.
Is there any truth to this.
Thanks,
Kannan

Kannan,
Surely what you're describing is not a memory leak, it's a situation where collection is postponed until a process of indeterminate time reduces it's processing use sufficiently.
I'd describe that as thrashing rather than leaking... 
You reckon??

There have been some instances where gc does leak memory, check James post below, I was actually more thinking about the scenario and possiblity of such occurance.Imagine having a real-time app. which reads tons of data and displays them in a chart in several windows, this requires frequent memory allocations and is also processor intensive.
Cheers,
Kannan

There is also a bug in .NET 1.0 where the GC would fail to free memory more than 8MB was allocated. Typically you'd see this when you have a large struct and create a large array of them.
I'm not wording that description correctly, but it isn't a problem you'd often see unless you were doing long [] arr = new long[int.MaxValue] or something like that.
Gah, I just can't find the right words 
[edit]Forgot to mention that this is supposed to be fixed in .NET 1.1[/edit]
