I need to display images that are stored in a database without any meta
information such as their size or type (gif, jpeg, etc).  I can create a new
Image object from the byte array returned from the database, this allows me
to determine the size easily but I can't figure out a ...

I get a generic error (not very helpful) when attempting to save a
re-sized image back to its original location. Here is the code snippet:
       Dim g As System.Drawing.Image =
System.Drawing.Image.FromFile(Me.File1.Value)

i've crated a custom control that allows user to draw selection
rectangle over a bitmap. the selection rectangle is semi transparent and
also implements cool "Marching Ants" feature :). the marching ants are
moved by a timer set to interval of 100.

I have a PictureBox on a form. I need to drag the image exposed by the
PictureBox "image" property to a window of Windows Explorer (or to the
desktop).
The new file will have a name assigned by the programmer, for instance

I am drawing a selector on my image for cropping purposes. It is done in
black, however if the image is real dark this doesn't show up well.
How can I determine the darkness of an image, or areas of an image so that I
can know whether to use black or white?

I have a Splash form with text drawn on it over a gradient color scheme.
This same form is shown as the 'About..' box
When the form is shown as the About dialog, I want to add a close button in
the top-right hand corner ... but I don't want to use a control like a label

I have a little problem with a toolbox I'm developing in C#. I want to
make a tool to create a GraphicsPath object consisting of a rectangle
with some lines in it - where the size of the rectangle as well as the
placement of the lines are determined by parameters.

I got the following error when I am trying to save a tiff file using
bitmap class
"Invalid parameter used"
faxPageImage = new Bitmap(fileName);  //Error Line.

I'm looking for a way to directly print to the printer. With directly I mean
I don't need any driver. Just add a printer on the LPT1 (without registering
it first in windows) and send data to it.
The problem for me is that I have to work with really old printers

I need to write some strings on a Graphic surface of a simple control with a
color that is not blend with background color.
To get this, I simply need set CompositingMode to SourceCopy.
This is the code:

I have not messed around with Flash, but have been very impressed with some
ui's I've seen that move viewports around selectively exposing a hidden
picture. And I have seen animations of bitmaps that were remarkably smooth.
Even Microsoft uses Flash :

Do you think it is legitimate practice to mix GDI+ and GDI calls (via
Get/ReleaseHDC()) in paint event of a control? I've heard there is
possibility of performance loss while "locking" Graphics object which
is done as a side-effect to GetHDC() call - could you confirm? Another

I have written some code that creates and draws into an 8bbpIndexed
bitmap using LockBitmap and direct memory access, and then saves this
as a GIF.
(bitmap pattern: The bitmap is filled with lines of different colours.

Does anyone have an example of an Ellipse user Control that properly
expands the control container so the ellipse is NOT chopped off.  It
has been mentioned to use Flatten on the Graphics path and then get the
Min/Max X and Y's but I am seeing inconsisten behavior on what that

I'm having trouble making a multipage tiff image that is only 1bpp
since it will be holding fax information. When I try to alter the pixel
format I get "A Graphics object cannot be created from an image that
has an indexed pixel format."
