You're right. Only Framework 2.0.
In this case, you can identify them by location.
Or by name - concatenate some string to name, and then parse it.
Label[] labels = new Label[100];
for (int i = 0; i

Thankyou!
But, if I have 400labels, to catch "OnMouseDown", do I must write 400funtions (each of labels has a funtion)? If not, I can group all and set event is "OnMouseDown", but how to know "label_1" but not is "label_2", when I click on one?
Thank for read!

You can get the index of label by this code on mouse down event
<br />
private void SplashForm_MouseDown(object sender, MouseEventArgs e)<br />
{<br />
int index = int.Parse(((Label)sender).Name.Replace("Label_",string.Empty));<br />
}<br />
Your label names must be: Label_1, Label_2, Label_3 ....
But I think 400 labels isn't good decision.
Can you use some custom control instead ?
Best regards, Alexey.

Thank you verymuch!
I know, 400 labels isn't good decision, That make my Program slowly. But, I could found the other instead!
My project is a game that name "Caro". In that game, have 2 player, one use character "X", the other use "O", put on a "space game"( that is 400 labels, a matrix 20*20).
When I design 400labels, automatic, C# will create separately 400 labels. To overcome, I myseft write code in "InitializeComponent()" funtion is "System.Windows.Forms.Label[] myLabels=new System.Windows.Forms.Label[400]"... then it not visible in "Form1.cs [Design]" but haven't any error, and when I build it, and press "F5", in my window of "Form1", I can see immediate 400labels???????  I don't understand!
Thank for read!

I try to draw one pixel wide dashed lines in gdi+, but the result is very different from the one obtain with the gdi api functions. Te big problems are on diagonal lines or the lines which are not horizontal or vertical. If someone knows how to draw this lines in gdi+ with the same visual efect as in gdi please answer. I try with or without SmoothingMode, with or without PixelOffsetMode but the results are no better.
The best difference is on custm dotted lines with one pixel on - one pixel off

Here's how you use the FromFile method:
Image img;<br />
img = Image.FromFile("C:\\test\\1.tiff");
---
b { font-weight: normal; }

Thanks but if you download the image file and run this code it will not work.
this image has jpeg compression you can load it in office document imaging but cannot in .net.

There is something wrong with the file. Some programs will open it, but Photoshop refuses to. How have you created the file?

b { font-weight: normal; }

this is a tiff file compressed with jpeg algorithm.
when I scan the image my scanner returns me this format image

This happens because GDI+ doesn't fully support JPEG compression in TIFF files. You'll have to either use an uncompressed version of the file or one compressed using LZW.

I found that very few programs open this file. Further exploration found that it uses a largely obsolete form of JPG compression. Check if there is a new driver for your scanner. You could also try using IrfanView (a free program) to batch convert your scans.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

i am trying to write a c# program communicating to a device (PLC) using socket. the communication is in hexadecimal. everything are alright - socket connection, socket send and received etc. i had created a byte array for the socket's send.
for example, 2 bytes are use to send a decimal value of 100. this is fine.
byte[1] = 0x00;
byte[2] = 0x64; // 64 hex = 100 dec
however, i am having problem to send a decimal value of more than 255. for example, to send a decimal value of 300,
byte[1] = 0x01;
byte[2] = 0x2C; // 12C hex = 300 dec
if i read back form the bytes array, instead of getting the decimal value of 300, it's becomes 144 - byte[1] = 1 and byte[2] = 44.
i am not quite sure if i should use byte array to store the hex value since it will be converted to hex decimal value separately. i had tried to use string array but enventually i still need to convert to byte array in order for the socket to send out. the smae
i am looking forward for your advise. thanks indeed.

The device probably needs a signed byte, so try that

That's exactly what you put in the array, you are only adding the values wrong.
256 * 1 + 44 = 300

Uhmmm, do you call yourself a developer? With all due respect, I suppose you are working for one of the Indian companies that is robbing Americans of jobs. Figure it out yourself and then ask questions if you run into problems. That is what REAL developers do.

ADOcon = (ADODB._Connection)mydlg.PromptNew();
OleCon.ConnectionString = ADOcon.ConnectionString;
OleCon.Open();
if (OleCon.State.ToString() == "Open")
{
MessageBox.Show("Connection Opened");
