Im trying to find a way to add linesto files\folder tooltip using C#.
for example when I would point on some file in window I could see it's name and also some customize information. for example in the following file I would like to add the current version of Itunes program.
The file you would want to modify is called Desktop.ini
To modify/create .ini files with C#, refer to this article from codeproject.com

I think I got Clipboard wrong but I would like to know or get a tip how I would need to implement this. I would like to have this program running in the background and every time I copy something it ends up in the program. That way if I would like to go back in time to see what I copied 10 min ago I'll find it in the program. So I guess I need to save it in a text file. How do I got about implementing this?
C# can't normally raise events when the clipboard changes. You can read data from the clipboard, and you could busy-wait polling the clipboard, but those seem non-optimal to me.
However, with a little bit of extern usage, you should be able to get what you want. In a class which subclasses Form:
/// <summary>
/// Message id for data being copied to the clipboard
/// </summary>
/// <value>776</value>
private const int WM_DRAWCLIPBOARD = 0x0308;
/// <summary>

Make sure MyForm_Load is added as an appropriate event on the Form (most easily from the designer window).
I'm trying to write general interactive shell wrapper class from c#/.Net using CreateProcess() for Dos, Powershell, Plink, etc, and I've found the article Why does StandardOutput.Read() block when StartInfo.RedirectStandardInput is set to true? to write wrapper classes which redirect child process's stdin/stdout for getting powershell command execution output. As he directed, I got his source code from http://sixfeetsix.blogspot.com/2012/08/interacting-with-sub-processed-shell-in.html. However, any command line execution such as plink.exe, cmd.exe works great for redirection of stdin/stdout but powershell.exe doesn't get me the input/output correctly. It looks like powershell.exe doesn't inherit from parant process and thread for pipe. Would you give me any feedbacks for getting retValue as of "get-help" powershell command successfully?
When I run "dir" command from DosShell, it returns the output of dos command "dir" successfully. However, Powershell doesn't return "get-help" command from powershell prompt.

powershell is different. I think you can not simple redirect its input and output. that's why we need to use runspace to get the output object. search "powershell c# example", lots code. here is a simple one:
Calling PowerShell From C#
depends on the powershell you use (exchange powers shell, sharepoint power shell..), you will need to add the correct snapin.
It sounds like you don't want to just call powershell commands from C#, but to act as a powershell host. Being a powershell host allows you to receive the output from commands like Write-Host and Out-String and just have a stream of strings as input and output. Examples of hosts are powershell.exe and powershell_ise.exe, but it can be a lot of work and won't make processing the results of powershell commands easier, only harder. The power of powershell is that the input and output of commands are real objects, not just strings. You can read more about it here.
If you just want to execute some powershell commands and receive their output you would be better of with this here and work with the objects the powershell commands are returning instead of wanting them to be strings. This means you have to stop using commands like Write-Host, Out-String, Format-Table, etc. Those are for formatting, not for processing results.
I have the problem that I can't seem to make GetRawInputDeviceInfo in combination with RIDI_DEVICEINFO (to try to retrieve a RID_DEVICE_INFO) is not working at all.
I get the error -1 back from the function, what should mean that there is not enough space to store the RID_DEVICE_INFO, buy I tried already to increase it to the more then needed but the effect the same.
I used the following DLLImports :
[DllImport("User32.dll")]
extern static uint GetRawInputDeviceInfo(IntPtr hDevice, uint uiCommand, IntPtr pData, ref uint pcbSize);
[DllImport("User32.dll")]
unsafe extern static uint GetRawInputDeviceInfo(IntPtr hDevice, uint uiCommand, IntPtr pData, IntPtr pcbSize);
Both with no result, but when I try these with RIDI_DEVICENAME they both work just fine.
In this case I call the function like this :
first to get the size: GetRawInputDeviceInfo(rid.hDevice, RIDI_DEVICENAME, IntPtr.Zero, pSize);
and then : GetRawInputDeviceInfo(rid.hDevice, RIDI_DEVICENAME, pData, pSize);
to get the name. Both work fine, but when I call the function like this :
int intReturn = (int)GetRawInputDeviceInfo(rid.hDevice, RIDI_DEVICEINFO, IntPtr.Zero, pInfoSize);
intReturn = (int)GetRawInputDeviceInfo(rid.hDevice, RIDI_DEVICEINFO, pInfoData, pInfoSize);
Then at first I get 0 into intReturn and also can get the correct size,
but then I get -1 into return, and whan I do a PtrToStructure it just returns wrong and seemingly random values.
Also when I after that do a GetLastWin32Error(), it return sometime 1008 or 87 , what also seems not to make any logic to me, because I don't see where I could have made the wrong parameters.
I defined RIDI_DEVICENAME and RIDI_DEVICEINFO as :
internal const uint RIDI_DEVICENAME = 0x20000007;
internal const uint RIDI_DEVICEINFO = 0x2000000b;
Can anyone help with this problem or show me a working C# example for GetRawInputDeviceInfo ?
Thanks,
Peter

I stumbled on this code below and tried to implement it in my WinForm App to help my users as many are very NOT tech-savy.
Unfortunately, it does nothing. It does not generate any errors or anything. It just doesn't make it Flash.
Can anyone offer any insight? I have tried it on Win 7(x64) & Win XP (x86) with the same results on both.
I am calling it like so --> TaskbarFlasher.FlashWindow(this); From my Main Form.
[DllImport("user32.dll")]
private extern static bool FlashWindow(IntPtr hwnd, bool bInvert);
[DllImport("user32.dll")]
private extern static IntPtr GetForegroundWindow();
/// <summary>
/// Notifies the user that the application requests attention
/// by flashing the taskbar if the form is not the current window.
/// </summary>
/// <param name="myForm">The form in question.</param>
public static void FlashWindow(Form myForm)
{
// if the current foreground window isn't this window,
// flash this window in task bar once every 1 second
if (GetForegroundWindow() != myForm.Handle)
{
FlashWindow(myForm.Handle, true);
}
}
Nevermind, I figured it out with the Following Links Help --> http://pietschsoft.com/post/2009/01/26/CSharp-Flash-Window-in-Taskbar-via-Win32-FlashWindowEx.aspx
