Luckily I know how to do that but sadly a picture box doesn't behave exactly like a form I didn't find any attributes regarding the opacity of a picture box in the code view

you will need to use ImageAttributes and ColorMatrix

ImageAttributes ia = new ImageAttributes();
ColorMatrix cm = new ColorMatrix();
cm.Matrix33 = 0.5f; // half transparent
ia.SetColorMatrix(cm);

now you can use above ImageAttributes instance when drawing image.

Look at the Opacity property of the Form and set it to a number close to zero

I cant because that will also fade the controls on the form. I need to fade only the background of the form.

what about trying something with the TransparencyKey property of the form.

you could try setting the form to be Red then using Red as the key, that way you may still get the controls full opacity. Im not 100% on this thou, do you want the form to be completely transparent or still some visible?

TransparencyKey works only with exact color.

I actually wonder what is taught on collleges, if we always get question by clearly clueless people.
I mean, college is hardly learning by doing, it should much more theory than praxis.

So, that must mean people that post such clueless questions here don't pay attention during lessons.

i want 2 delete in array element .. [modified]

this is my array syntax..

int[,] numbers = { { 1, 1 }, { 1, 2 }, { 1, 3 }, { 2, 4 }, { 2, 5 }, { 2, 6 }, { 2, 7 }, { 3, 8 }, { 1, 9 }, { 1, 10 }, { 2, 11 }, { 3, 12 }, { 2, 13 }, { 1, 14 }, { 1, 15 } };

now my question is

i want 2 delete frist element of 1's means delete {1,1},{1,2},{1,3},{1,9},{1,10},{1,14},{1,15}

my o/p should be like this :{2,4},{2,5},{2,6},{2,7},{3,8},{2.11},{3,12},{2,13}

please can u tell me how to do this ..

edit: sorry copied the wrong thing first

but now more serious, you probably have and array of small 2-length arrays and you want to remove the fist of all pairs and let the rest fill up the gaps Without knowing the array in advance. Otherwise it just doesn't make sense.
But that isn't too hard..

Ok yes let me help some more then, cause I didn't actually do anything to help yet
Anyway, what I would probably do, if it is sure that you number of elements will halve, create a new int[2,length/2] , scan through the old array and only use the correct places like:

int[,] result = new int[2,array.GetLength(0)/2];
for (int i = 0; i < array.GetLength(0); i++)
{
   result[i&1,i/2] = array[1,i];
}

I hope that is what you mean?

edit: aah no it is not what you mean, but it's close..
Ok this is harder, since you don't know the size of the result yet..
maybe first put all elements that are not 1 into a List<int> and then turn that into an int[2,List.Count/2] ?

Re: i want 2 delete in array element ..

harold aptroot24-Mar-09 2:36

24-Mar-09 2:36

OK new code

List<int> temp = new List<int>;
foreach (int i in array)
   temp.Add(i);
int[,] result = new int[2,tmp.Count/2];
for (int i = 0; i < temp.Count; i++)
  result[i&1,i/2] = temp[i];
