Grab the mouse in your preferred mouse hand.
Move the cursor (white arrow thingy) towards the bottom left corner of the screen.
Click the "Start" button
Click the "Run" menu
Type in "Notepad"
Click OK
Click File | Open
Open the required file
Edit the file
Click File | Save
Click File | Exit

As of how to accomplish this, have you ever tried Google?
Failing that try Badger | [badger,badger,badger,badger...]

Ah, now that's a problem. It's much too complicated for exceptional people to understand.

The hardest solution would be to use the keyboard (by pressing wierd combinations).
The simplest solution would be to go out and buy another computer with an RS232 port, setup a serial mouse and then using scripts in Hyperterminal or a similar program to provide the necessary signals to move the mouse.

As of how to accomplish this I wouldn't have a clue at the moment and I'm too lazy to google it

Just plug the cat into your computer. If your cat is plug'n'pray compatible, you should get a cat pointer instead of the mouse pointer, but it works the same. Smile | :)

To my understanding, you meant, "How to read and write .TXT file". If so,

// READ
string readContent = System.IO.File.ReadAllText(string fileName) // .txt File name.

//WRITE

System.IO.File.WriteAllText(string fileName, string contentToWrite)

Is there a way to take a array of bytes and run those bytes as a program without saving them to any type of disk, only run those bytes form memory?

Yes

Are those array of bytes a .NET program? If so, yes, you can run them from memory using System.Reflection.Assembly.Load

I have tried this I built a little test app that looks like this but I really did not get much of a response from the stuff I tried loading is there something I am doing wrong?

OpenFileDialog open = new OpenFileDialog();<br />
                if (open.ShowDialog() == DialogResult.OK)<br />
                {<br />
                    System.IO.FileStream st = new System.IO.FileStream(open.FileName.ToString(), System.IO.FileMode.Open);<br />
                    System.IO.BinaryReader br = new System.IO.BinaryReader(st);<br />
                    byte[] bytes = new byte[br.BaseStream.Length];<br />
                    br.Read(bytes, 0, bytes.Length);<br />
<br />
                    System.Reflection.Assembly a = System.Reflection.Assembly.Load(bytes);<br />
                    a.CreateInstance(a.GetType().ToString());<br />
                }

Are you getting some exception with that code? What exactly doesn't work?

On some things I get a exception that looks like this, but then on some things it just dosent do anything.

"Could not load file or assembly '1453384 bytes loaded from asmTest, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. An attempt was made to load a program with an incorrect format."

i just started a socket application that recieves UDP data. The data that i am recieving is a netflow packet from cisco devices. to learn how to do this i have been searching the forums and looking at other people's code for reference. some code that i came across was the following. pretty much what you do is, passed a byte[2048] to the procedure ToUInt and specify the starting point to get the datafield in the byte and the length from that starting position to get. the first field in the packet is the version field which starts at position 0 and is 16 bits long. so you would end up passing to the following code the byte[2048] of your data buffer, 0 for your offset and 16 for your length. i understand mostly all of the code except that part there the Shift Right occurs and the ANDing against 0x0001.

b is 10, and then after the bitwise operations is it 5. which is the correct version number for the netflow packet that my application recieved.

public static uint ToUInt(byte[] datagram, int offset, int length) {
uint total = 0;
int byte_index;
int bit_offset;
int bit;
byte b;

for ( int i = 0; i < length; i++ ) {
bit_offset = (offset+i) % 8;
byte_index = (offset+i-bit_offset) / 8;
b = datagram[byte_index];
bit = (int)(b >> (7 - bit_offset));
bit = bit & 0x0001;

if ( bit > 0 ) {
total += (uint)Math.Pow(2,length-i-1);
}
}

return total;
}

i modified the code to print to a console the values of each variable during each iteration of the loop. here are the values.

i bit_offset byte_index b bit total
0 0 0 0 0 0
1 1 0 0 0 0
2 2 0 0 0 0
3 3 0 0 0 0
4 4 0 0 0 0
5 5 0 0 0 0
6 6 0 0 0 0
7 7 0 0 0 0
8 0 1 5 0 0
9 1 1 5 0 0
10 2 1 5 0 0
11 3 1 5 0 0
12 4 1 5 0 0
13 5 1 5 1 4
14 6 1 5 0 4
15 7 1 5 0 5

i relize that the byte_index is just a counter for how many bits you have iterated through. once you went through 8 bits, incriment the byte index by 1. since the length is 16, that is two bytes and that would account for 0, and 1. i is just the counter set to the length of 16. i don't understand the B, bit, and total values. could someone explain the logic behind this to me?

I have added comments to part of the code:

// calculate what bit to get in the byte<br />
bit_offset = (offset+i) % 8;<br />
<br />
// calculate what byte to get<br />
byte_index = (offset+i-bit_offset) / 8;<br />
<br />
// get the byte<br />
b = datagram[byte_index];<br />
<br />
// shift the byte so the desired bit is at position zero<br />
bit = (int)(b >> (7 - bit_offset));<br />
<br />
// clear all bits except the one at position zero<br />
bit = bit & 0x0001;<br />
<br />
// calculate the value of the bit and add to the total<br />
total += (uint)Math.Pow(2,length-i-1);<br />

VB SCRIPT issue : called from C#

Re: VB SCRIPT issue : called from C#

Hi,
I am using VB Script by calling the script as a shell execution. Diagnostic.Process.Start(....)

But unofrtunately, the Process's EXITED event is not being fired ever. Looks like, the process is never being ended. Is there any reason why.

moreover, do I need to ship any pre requisite software to run VB Script along with my C# application to my client's Computer ?

I don't have that experience with VBScript. What's the extension of the file of your script, and what program that actually excutes the code?

bashiwala wrote:

Well that means that the program didn't ended at all. It's up to the code that you wrote in that VBScript to end itself or go into an empty loop for example.

AFAIK scripting languages don't produce stand alone exe files. scripts like VB need to be excuted inside another program -eg. Access, excel, etc..-. What exactly does your script do? and what program excutes it?
