Re: Line Numbers display....

Hi,
How to skip the single line from the graph while plotting the number.
consider the numbers from 0 to 9 it will be as;( in the For Loop)
Working format:

|||||||||| ---> Graph lines
0123456789 ----> X axis numbers

I need to have the format like;

||||||||||||||||||| ---> Graph lines
0 1 2 3 4 5 6 7 8 9 ----> X axis numbers..

Thanks,
Subbu

0. It is considered rather bad maners to have multiple unanswered questions.
1. Have you considered using a graph library, zGraph is very good.
2. Format your code, this is a pile of pants:
|||||||||||||||||||
0 1 2 3 4 5 6 7 8 9

But this is purdy:

||||||||||||||||||| 
0 1 2 3 4 5 6 7 8 9

Hi,

I am new to C#.I have to develop an MDI apps in C#.
Can anyone give me a sample C# MDI Application, If you have any?

Hi,

I need to plot the wave format on the usercontrol screen with the use of text file(having input values about 2gig). Horizontal Scrollbar is placed on the panel and if I move the scroll bar the panel should move for certain amount values.

Is it optimal to use the lazy loading technique here.How? Is there any other way to accomplish this task?

Consider the screen width is 300 and wave columnwidth of wave is 30 and the total numbers to plot wave is 3000.

Then 300/30 = 10 waves can be drawn.

How to set the Largechange and Smallchage in the Horizontal Scroll event?

Thanks,
Vel

I would suggest seperating out your problem.
0. File reading
What is the format of the file?
If it is a fixed length format, can you can read directly any portion of it?

1. Display scroll bar:
Set the scroll bars range to be 0-2990 - the max value is {number of items} - {items to be displayed}
Set the small change to 1, you are moving by a single frame.
Set the large change to 10, you are moving the entire page width.

Thanks Vilmos...

Text File format and it's not fixed length I read from text file and have the values in an ArrayList and I loop through it.

How to set the scroll bar range? Any property need to change?

Getting the 10 values from above arraylist and planning to plot the value as a wave during Horizontal_Scroll() function when scroll left and right? How to achive this?

Subbu

This does produce an overhead in that you need to read everything in upfront, but it's not the end of the world.

Once you've read the file, you'll have the number of items in your list:

hScrollBar1.Maximum = this.listOfValues.Count - 10;

     x++) {
    // do some majic

Thanks Vilmos,
Still I need to clarify some doubts and i will send you the source code fully so that you can give the optimal solution. will you please give your email id?

I don't want to see your code, I have enough to deal with my own. Go figure out what you can and should you have any more questions then you are free to come back and ask. Someone is sure to answer if you ask well.

How do you find value of bits in byte

22-Jul-09 1:00

Yes I will do it. Thanx

gwithey20-Jul-09 23:34

20-Jul-09 23:34

I have looked in all my books and on the net and cant find a way to do this, it just tells me about shifting bits which will not be appropriate.

I have a program that recieves a byte[] from an external source.
The array elements represent different things eg(byte[0] bit 1 (rightmost)) = buzzer state (1 on: 0 off)

In the command i recieve there will be 3 bytes, with each contained bit representing a buzzer or LED and its state on or off;

Does anyone know how i can look through the bits and check there state?

Thanx George

You can use the BitArray class to check the value of single bits into a byte array.

gwithey21-Jul-09 0:30

Thanx for the advice this looks like a useful class.

I tried looking through the byte with .length but noticed there was a get() position which is what i was looking for. As somthing like getchar()/ charAt() is perfect.

gwithey21-Jul-09 0:44

21-Jul-09 0:44

I think this is the idea

BitArray byte1 = new BitArray(commandData.Data[0]);
                 enumLEDAndBuzzer lcdAndBuzzState = enumLEDAndBuzzer.NULL;

                 if ((byte1.Get(byte1.Count - 1)) == 0x31) // 1
                 {
                    lcdAndBuzzState = enumLEDAndBuzzer.BUZZER_STATE;
                 }
                 else
                 {
                    lcdAndBuzzState = enumLEDAndBuzzer.NULL;
                 }
                  if((byte1.Get(byte1.Count - 2)) == 0x31) // 1
                 {
                 }
                 else
                 {
                    lcdAndBuzzState = enumLEDAndBuzzer.NULL;
                 }

From my understanding i should be able to work from right to left by (count - 1++).
Thanx again

Hi,

shifting is the key. Wink | ;-)

byte b = 0xaa;
if ((b && 0x01) > 0)
{
  //bit0 = 1
}
else
{
  //bit0 = 0
}
if (((b >> 1) && 0x01) > 0)
{
  //bit1 = 1
}
else
{
  //bit1 = 0
}

etc.

bye

It looks like a good idea i just cant get it to work as i cant compare the byte to 0x01
