I have to pass pixelformat as a parameter when performing lockbits. But for grayscale images, there is only "Format16bppGrayscale." Does this format work with 8 bit grayscale images? If not, how do i use lockbits with 8bit grayscale images?
|
|
|
|
|
No. Use PixelFormat.Format8bppIndexed.

if its 8-bit then shouldn't the values range from 0-255? I get black pixel as 0 and white as 169. Is this what its supposed to be?
|
|
|
|

Hi,
169 is two thirds of 255, as if you started off with an RGB image and
either one component was absent, or something else went terribly wrong in the
color-to-grayscale conversion.
Or did you have an ARGB image (A=alpha=opacity) and take the wrong 3 out of 4 bytes?
|
|
|
|
|
Hmm it must be the website that i downloaded the image from. Im using the Lena picture in grayscale, which i previously downloaded.
I downloaded the color version of lena and converted into grayscale using photoshop. Pixels return intensities properly now. Thank you.
|

Are you sure that it actually is a grayscale image, and not an indexed image that had a palette of 170 grayscale colors?
I found one Lena picture in grascale, that is a GIF image with a 215 color palette.

Hi,
I have a form with a listbox controls that has some items in it.
When i double click a item from the listbox it opens a new form that as the title of the item.
(you will see that on some chat applications)
OK, code for the above is fine.
Now, i don´t want to open new forms with the same title, i want to prevent that.
If a form titled "bob" already exists and i double click "bob" item from the listbox, i want the existing form to be focused not open another form with same title!!!
Can anyone help me here?
how can i count forms, get their titles so that a can achive that
i suspect that i have to create some kind of mdiparent/child forms to do that.
Thanks

Hi,
you could keep a Dictionary<string,form> that maps titles to Forms, and before opening
a new Form, look for an existing one if any, then act accordingly. You would have to
remove entries when forms get closed then, using the Closed event.
Or use Application.OpenForms and search for a matching title.

I searched articles in codeproject and i found an anser in mdi.

Hi,
I am using C# to insert a date value from the DatePicker into a DateTime
filed in mySQL database.. I am using the following syntax:
'" + datePicker.Value + "'
Plz Help.Thanks In Advance.
|
|
|
|
|
If you want the date part only, you should "'" + datePicker.Value.ToString("yyyy-MM-dd") + "'"
to include the time part too "'" + datePicker.Value.ToString("yyyy-MM-dd hh:mm:ss") + "'"
I hope it helps,
Dirso

Sorry guys i'm a bit of a newbie still... 
But anyways here's my question.
I r multithreading! however it's not looking so good... I'm using a beginInvoke to fire off pings at other machines on my network I'm pulling the names from ldap sychronously. Anyways the question i had was "Are async delegates manged by the threadpool"... I thought i read somewhere that they were indeed managed via the threadpool... So next question is how come when i do something like this "ThreadPool.SetMaxThreads(10,10);" The app still fires off the max threads that the threadpool can manage? I.e. 20-25... Hope someone can shed some light on this.. Lemme know if you would like to see some code if that would help define my question/problem! Thanks in advance for any reply's even if it's stfu noobzor and go read a book!

SqlConnection cn=new SqlConnection("database=durdu;user id=sa;pwd=");
SqlDataAdapter cmd=new SqlDataAdapter ("select * from marksheet",cn);
DataTable dt=new DataTable();
cmd.Fill(dt);
axPivotTable1.DataSource=(msdatasrc.DataSource)(object)dt;
this throws an error -specified cast is not valid.
i have done lots of googling and does not found single satisfied answer

hi
Dont ever say Urgent again, we dont work for you.
Secondly mybe you can write your code like this
SqlConnection cn=new SqlConnection("database=durdu;user id=sa;pwd=");
SqlDataAdapter cmd=new SqlDataAdapter ("select * from marksheet",cn);
Dataset ds = new Dataset();
DataTable dt=new DataTable();
cmd.Fill(ds);
dt = ds("My_Table");
axPivotTable1.DataSource=(msdatasrc.DataSource)(object)dt;
Remember not to use the Word Urgent here

What benefit would a DataSet be?

You can't cast an object to something that it isn't. You can only cast an object to it's actual class, any of it's base classes, or any of the interfaces that it implements.
C# is type safe, so the object contains information about it's actual type. When you do a cast, you cast the reference, but the object still remains the same type. Therefore, when you cast the DataTable reference to object, you get an object reference pointing to a DataTable object. You can't then cast this to msdatasrc.DataSource, as the actual type of the object does not inherit that class.
If the control can't use a DataTable as data source, you have to copy the data from the DataTable into something that the control can use.
