Hi,

Your problem is reading and writing byte by byte. Instead you should read as big blocks (like 4KB each at least, as NTFS cluster size is this) XOR'em on the memory and write'em back as...

Hi,

Try using ExitWindows or ExitWindowsEx Win32 API calls with P/Invoke.

Loren Soth

Hi,

You can either use P/Invoke to access Win32 Api calls, it supports analog reading but I don't think it supports vibration. You better use Managed DirectX 9 classes to use DirectInput.

Hi,

Like libpcap (core of WinPCap I previously mentioned) libdnet also requires you to load a driver to your computer but different than libPcap it can drop packets, change routing tables or...

Hi,


void change(string s)
{
label1.Text = s;
}

private void button1_Click(object sender, System.EventArgs e)

Hi,

If you have a specific XML schema, you can use a DataSet not bound to a database or connection and provide your own schema. This way you can use all data bound controls and table cursors and...

Hi,

First can an OS be coded in C# ? The answer is yes http://research.microsoft.com/os/singularity/ although it is pretty a proof of concept type of OS. Still it is one of the most fascinating...

Hi,

The creation af a thread or calling a function from the event won't help at all because the creation of a new thread object and the thread it self on OS plus the necessary context switching...

Hi,

Nice singleton pattern by RamyMahrous but GetTheOnlyInstance()
could directly return the Image myImage and from .Net 2.0 instead of defining a private contructor to make a pure static class...

Hi,

You can't write kernel mode device driver in managed code (C#, VB.Net) which is required to write network filter driver which can drop packets (main functionality of firewalls)
You can...

Hi,

You can use String.Split(" ") to get an array of words of your string, this way you can also know the number of words on that string. (if you plan to use multiple possible sentences)
...

Hi,

Do you need an industrial strength encryption (like AES, 3DES) or just need to scramble the content to make it human unreadable. For the former you have to use System.Security.Cryptography...

Hi,

If you aren't porting old code (actually even if you do so), or has a valid reason to use that ActiveX control, you would be much better off using System.Net classes performance and debug...

Hi,

For forensic disk access you can't trust to the file system or the OS file/disk APIs (WIN32). MFT for NTFS and the FAT for FAT32 file systems may be corrupt or tempered. Sectors might be...

Dear BeyerCorpuz:

C#

Loren Soth

Hi,

I doubt that you can create that separate hook dll with managed code but you can create the app managed and the dll native code (C++, Delphi).

Hi,

As celikada already mentioned there are different bluetooth stacks available and Microsoft hadn't provided one till XP SP2 (if I'm not mistaken) still most USB BT dongles install their own...

Hi,

Check http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnmsde/html/msdedepl.asp and ...

Hi,

I am not sure but the four parametered version of the FromArgb takes Alpha Red Green Blue (where Alpha is opacity/trasnparency) but still you must adjust the GDI+'s brush or copy mode I...

Hi,

I thought one of those events pass the ListViewItem object as parameter just like TreeView returns TreeViewNode but I was mistaken.
You can use just "tbSearch.Text =...

Hi,

Try lv.selecteditems[0].subitems[2].text;
If you use ItemActivated or SelectedIndexChanged event then you can avoid lv.selecteditems[0] and directly call the ListViewItem passed as a...

Hi,

Even if you manage to alter the data w/ JScript on the client side grid you see in the browser, this will not affect the datagrid object and the bound dataset on the server. If you don't...

Hi,

If you are using System.Drawing (GDI+), you can use "System.Drawing.Color.FromArgb(Int32, Int32, Int32)".

Loren Soth

Hi,

If you are trying to do a local firewall which protects the installed PC only (like ZoneAlarm) then you have to write a Network Filter Driver which is a kernel mode module like any device...

Hi,

The second part is almost the same solution alc6379 suggested (encapsulate in a property) I just reminded that VS 2005 has a feature to make this get/set code generated automatically via...

Hi,

Do you override any thing about the definition of property called Position ? If not then your problem is you try to use += variable on a value type member of position but position it self is...

Hi,

Your problem is with compiler, the above fixes are correct. You create a bool msg but it gets assigned a value only if(txtuserid==args.Value) and also the only return statement is in this...

Hi,

Your code is confusing and require some cleaning up. I suggest that you put the ststic void main in a separate class than your base classes. The class name LinkList is misleading because as...

Hi,

You have some options. Your first and best bet is to use JNI to expose Java functionality native codes and consume them through Platform Invoke. A more exotic approach would be to use one of...

Hi,

You can make your controls databound to a field on a dataset but if you just need to bind it to a variable declare your variable as private in your class and encapsulate it as a property...

Hi,

You can use TcpClient and TcpListener classes from System.Net.Sockets name space to use standart TCP communication. If you are implementing a protocol of your own use any port you like...

Hi,

I can provide you a C# implementation of CRC32. (you can easily find one googling too) But if the speed is of essence (making managed MD5 unusable) you might prefer to use a native code...

Hi,

You must put the lblFactorial.Text = factorial.ToString("n20"); after the while loop.

Loren Soth

Hi,

TcpClient is for raw socket access and isn't convenient. HttpWebRequest is possible but you have to code all the SML and SOAP parsing, composing code. Best way to do this is to consume the...

Hi,

It is limited with your Virtual Memory Size (if you set to automatic management then it is limited to your free disk space on the drive where your page file resides) I successfully created...

Hi,

As you see is a direct descendent of System.Object thus it isn't an array or a collection. So you can't assign s = {"a", "b", "c", "d", "e"}. To make the class itself a collection you must...

Hi,

I assume you use VC++ 6.0 or VC++.Net (7.0) with unmanaged code in those the default variant type might be the same as OleVariant (especially when you select COM object as project type)...

Hi,

The previous post is pretty much optimized and must have solved your problem but if you have many entires on your DB you might want to use an SQL query like (Select * from <tablename> where...

Hi,

The problem here is that even XP don't come with a bluetooth stack unless you have SP2. So every body use a different bluetooth stack (my dongle came w/ Bluesoleil but there also is Widcomm...

Hi,

All those code are valid but they aren't encapsulation really. The purpose of encapsulation is to provide a layer of decoupling between the private variable and other objects which access...
