Hi Gurus! Here is a problem with wxPython. I would like to load bitmaps
and create a mask
for them at once. Here is my idea: the mask colour for the bitmap should
be the colour of
the pixel in the top left corner. (The same way Delphi does with
TImageList.) E.g. the
bitmap should be transparent everywhere with the same colour. I read the
documentation,
and I could not find an easy way to do this. Here is what I have tried:

I have an Windows application that displays lots of different colored lines in a Panel by using the Graphics.DrawLine method. The location and length of each line comes from a database query that takes two minutes to complete.
I am using the Panel's Paint event to call my drawing method, which accepts PaintEventArgs as a parameter. The problem is that every time the Window is moved or hidden, it needs to be repainted, which takes a long time...

I'm in a button clicked event on mainpage.aspx. I want to display a new
webpage that has just my image, which is a jpg. I want the page to be a
..jpg not an aspx so that it will be easy for the user to save to disk.
How can I do this?
Thanks,

I am using a ImageList with a bitmap that contains all the images.
I am currently saving the bitmap in a PictureBox, and load into the
ImageList when the form loads.
How can I save the bitmap into a Resource and load it from there later?
Thanks.

Hi,
Objective:
Draw a grid on a bitmap and set this as a panel's image. (Rather than
draw the grid directly on the panel and redraw repeatedly in the paint
event.)
Problem:
It works fine. I'm just not sure about disposing of the objects. I've
tried a variety of approaches but I find that when I redraw repeatedly

Hi Folks,
I'm not sure where this post belongs since I'm using managed vc.net, but the
issue is around GDI BitBlt.
Here is a summary of the problem:
- I am trying to copy a bitmap of my main form into a picture box.
- To do this, I bitblt using the device contexts of the form and a bitmap
object.
- After blitting, the bitmap image is always blank. I don't understand what
