Exactly the same (Although I never normally add a table name). The rest of your code looks acceptable.

The same way as any bit of SQL. Using DataAdapter.Fill(), Command.ExecuteNonQuery(), Command.ExecuteScalar() or Command.ExecuteDataReader()

You dont have to give the Table Name always
just specify the dataset object
da.fill(ds);

Hi All,
I am having one requirement for user selected color dropout in the image.
My requirement is that suppose user can load one image and select perticular part in the image and then press some button so my whole image should dropout that color from whole image.
can any body guide me how to do that?

Hi!
What do you mean with "dropout"?
Each pixel with the selected color will be made transparent? Assigned a different color?
The class Bitmap has the two methods GetPixel() and SetPixel() you can use.
This will be quite slow, though.
There was a discussion on fast image processing not so long ago. Try searching the C# forum, you should find some helpful links and approaches.
Regards,

Hi,
Yeah dropout means color filtering.I had successsfully filtered out the color from the whole image and it takes only 1 second so i am thankful to you.
Now another requirement is that i have to filter the color as per user selected area.
like
here i am describing whole:
when user select a particular area by rectangle then my function should filter(dropout) that color from whole image.
This is my requirement,Now can u tell me how to do that ?
|
|
|
|
|
When the user selects a rectangular area, there can be several colors included. Do you want to filter all these colors?
mav
|
|
|
|
|
Yeah.You understood my point.
I have to filter all these colors,so by that i am providing user facility according to his selected color filtered from the image.
what is now to do?
|
|
|
|

Hi,
Yeh Actually when user select one rectangle area then i am planning to take the Averange R,Average G and Average B value and after storing all the value in some object ,i can compare with all pixels and remove color which are related to Averange R,Average G and Average B,so can you tell me is that logic work for filtering the image in user selected color filteration?
can you pls tell me is that work out?

How many times are you going to ask this question? Better yet, how many times are we going to tell you that it's EXCEEDINGLY difficult and there is no reliable way to do it, before it finally sinks in? The answer is not going to change, so why keep asking the question?

I've heard that definition before. It's kind of startling to consider what trusted figures and institutions are rendered insane by that standard...
...door to door salespeople
...lots of executive level managers
...many organized religions
...whole humanitarian organizations
...the US penal system
...tier one technical support operators
Okay. That's enough examples. The definition is satisfactorily proven.

Hi
I need to convert a bitArray over to bytes, byte array.
Or write the bits out to file to be read again as bytes.
Any advise or help would be welcomed
Thank you.

Hi
Try this:
<br />
BitArray Bits=new BitArray(10,true);<br />
int ByteArrayLength=(int)Math.Ceiling(Bits.Length/8f);<br />
int CurrentByte=0;<br />
int CurrentBit;<br />
byte[] Bytes=new byte[ByteArrayLength];<br />
for(CurrentBit=0;CurrentBit<Bits.Length;CurrentBit++)<br />
{<br />
if(CurrentBit+1%8==0)<br />
CurrentByte++;<br />
if(Bits[CurrentBit])<br />
Bytes[CurrentByte]|=(byte)(1<<CurrentBit);<br />
}<br />

Thank you that is beautiful and simple, just what I needed.

Hi,
I'm changing jobs soon and my new boss likes me to become an 'expert' in Crystal Reports. So far I've only heard of it.
A quick look on MSDN pointed me from link to link to link, without any descent information. (I truly hate MSDN, I'm never quite able to find anything useful on it and it's always pointing me to other pages that has the information I seek (another link)  )
Can anyone give me a good link or point out where to look for a good start?
(So I'm a bit prepared when actually starting)
tnx!
No hurries, no worries.

See the Crytal Reports Help and practice a lot.

I had to learn CR on the spot as well, although this was back with v 8.5....about four years ago. The manual was very helpful and their free tech support line was also nice. But really you just need to play with it. Get a database with any data i.e. Northwind Cataloge from SQL Server, and just start creating reports from it. I thought the largest obsticle was learning the syntax of the formula builder. I was pro after a couple weeks...good luck

Yes, no need for books. Practice is the key.

Hi folks!
I will ask very simple question.Unfortunately I still could not understand the reason.
Suppose that you have a master-detail forms based application.When I open the detail form of the application I use the new keyword to create a new instance..It's ok...But when I try to access the Master form properties(for example Form1's textbox1) WHY DO I HAVE TO CREATE A NEW INSTANCEOF FORM1.Behind the scene it is already open..Right???
Please tell me something about this...
THANKS FOR ALL!!!!!!!!!!!!!!!!!!!!!!

Hi!
I don't know exactly what code you refer to but when you have two form instances, each instance has at some time been created using new.
If you try to access the properties of one form from the other one you have to have a reference to the other form.
If you don't have the reference, you can't access the properties, simple as that.
If you're trying to create a new instance in order to access some properties you're likely to access the properties of the wrong object.

ok, let me see if understand you... You have two (or more forms but lets just take two) forms one being the parent of the other (Master-Detail ?)
You want to open the child form and access the properties of the parent form from within the child form ?
Much like mav said just create a reference to the parent form....
public System.Windows.Form ParentForm=null;
ChildForm CF = new ChildForm();
CF.ParentForm=this;
CF.Show();
now you should be able to access all internal/public props and methods of your parent form from you child form.
NOTE: I did not test the above code, I just typed it....
