I have your project ready to go. Contact me off the board for ways to pay the $10,000 consulting fee for writing this for you.
Or, you can do your own project ( is it your job, homework or a rentacoder job gone bad ? ), and then we'd be happy to help when you're stuck.

I am using a keyboard hook to stop most if not all the keys on the keyboard but i am getting this message:
CallbackOnCollectedDelegate was detected
Message: A callback was made on a garbage collected delegate of type 'Client!KeyboardHook+HookHandlerDelegate::Invoke'. This may cause application crashes, corruption and data loss. When passing delegates to unmanaged code, they must be kept alive by the managed application until it is guaranteed that they will never be called.
any ideas how to solve it?

Error messages are so informative these days, that it almost gets too easy.
You have the solution handed to you in the error message already:
"When passing delegates to unmanaged code, they must be kept alive by the managed application until it is guaranteed that they will never be called."
You have thrown away your reference to the delegate. Don't do that.
Experience is the sum of all the mistakes you have done.

I'm porting my application from Window Forms to WPF, and as soon as i managed to get the first things working i run into a Random problem. I get series of several identical results in a row in WPF(the code is the same from Window Forms(where it works), i only needed to modify stuff related to getting the resource path and setting the image control). I can't see why this is happening it's totally unrelated to the code apparently. The way it's set now it can be seen when running the app and seeing identical sets of stars along the columns(it's filled that way).
Get the project here:
http://files.filefront.com/WPFMyMoOrar/;9061030;/fileinfo.html
edit:solved: it was reseeding so fast that it was getting the same time seed(so i moved the initialization of the random object to class scope), interesting that this problem didn't exist in Window Forms.

Well, maybe if you ask in the web development forum. You are aware that C# hasn't yet made it into the client side arena?

The other answer you got was obviously from a rocket scientist...
Why ask for javascript in the C# forum ? You want the web dev or ASP.NET forum ( although your question is not ASP.NET related as such )

Why on EARTH would you call 'tostring' on a string ?

Why am i getting this exception...
System.TypeInitializationException was unhandled
Message="The type initializer for 'Client.Form1' threw an exception."
Source="Client"
TypeName="Client.Form1"
StackTrace:
at Client.Form1..ctor()
at Client.Program.Main() in C:\Documents and Settings\Luis\Desktop\Server\Client\Client\Program.cs:line 21
at System.AppDomain.nExecuteAssembly(Assembly assembly, String[] args)
at System.AppDomain.ExecuteAssembly(String assemblyFile, Evidence assemblySecurity, String[] args)

at System.Threading.ThreadHelper.ThreadStart_Context(Object state)
at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state)
at System.Threading.ThreadHelper.ThreadStart()
I added this code to it....
In a different class from the main form i have this:
// the try and catch were there already
try{....}// see the finally statement for more info
catch(....){....}// i just warned that all files in the given file will be deleted
//this is the newly added code
finally
{
//path points to a given folder,specify by the Administrator during runtime
//
foreach(string npath in Dfiles)
{
File.Delete(npath);
}
string[] files = Directory.GetFiles(@"C:\Backup", "*.lais");
foreach (string npath in files)
{
File.Copy(npath, path, true);
}
//this is the same i have in the try statement
Dfiles = Directory.GetFiles(@path,".lais");//just to make sure i have all the files now...
if(Dfiles>0){
foreach (string npath in Dfiles)
{
tempor = File.ReadAllBytes(Dfiles[i]);
ms = new MemoryStream(tempor, 0, tempor.Length);
crypto = new CryptoStream(ms, Algorythm.CreateDecryptor(), CryptoStreamMode.Read);
crypto.Read(tempor, 0, tempor.Length);
Images[i] = Image.FromStream(ms);
crypto.Close();
ms.Close();
}
}
}
plus... in the main form i added this:
private static Hook hook = new Hook();
//handle the keys
hook.KeyDown += new KeyEventHandler(hook_KeyDown);
hook.KeyPress += new KeyPressEventHandler(hook_KeyPress);
hook.KeyUp += new KeyEventHandler(hook_KeyUp);
//users are not allowed to do anything with the keyboard
void hook_KeyUp(object sender, KeyEventArgs e)
{
e.SuppressKeyPress = false;
}
void hook_KeyDown(object sender, KeyEventArgs e)
{
e.SuppressKeyPress = false;
}
void hook_KeyPress(object sender, KeyPressEventArgs e)
{
e.Handled = true;
}
The hook class is fine, the project class worked fine with it... after i added the finally statement was when the exception came...
What i want is: "If before the application starts a file in the given folder has been modified/altered, a file has been renamed/deleted/created with the same extension" and causes a decripting error i would like that file to be deleted and inform of the deletion without stopping the application. Durin' Runtime i know how to restore files that have been altered/modified but before runtime is quite hard to me!
Please help...

Hi!
The exception tells you that the type Client.Form1 could not be initialized correctly, i.e. either the static type initializer (if you have one) or the initialization of a static member threw an exception.

Hi,
I want to go to particular line number in a text file directly. How we can do using c#???
Just When i send a line numnber in a function, it directly goes to that line.
please help me........
Thanks in advance

How do you mean, 'go to the line' ? If you use File.ReadAllLines, you can get an array and use an array index to access the line you want.

I dont want to read a line by lline from a text file.
My requirement is, the cursor directly goes to particular linenumber whatever i passed in function.
Ex: In Notepad, if we use ctrl+G - then it will takes directly to particular line.
In the same way, without reading data from text file line by line, i need to go the cursor directly...
