1.Control image property locking image file even after image cleared

Hi All

When I set a buttons image to a image file in the properties window it seems 
to lock the file even if I clear the button image property in the properties 
window

Sometimes I am editing the icon/bitmap and connect it to the button to see 
what it looks like

Then I want to make further changes so I clear the image from the buttons 
image property, but when I edit and try to save the image file I get a 
message saying it is in use by another program

I have to close the VB.net 2005 solution to free it up


Any ideas

Regards

2.VB6 create image, save image to memory, send image to asp

Ok, here is the deal, ive search all around and no one has this.

In visual basic 6 ( activex dll )
1. create a image in a picturebox control
2. save the picture in memory (not to disk)
3. place the saved picture into a stream or object that can be passed
to an ASP page

In asp classic
1. calls activex dll to generate image
2. set varable/object to the resulting image
3. display the image in the http ( as a locally cached .jpg, bmp, gif
or png, i dont care about format )

3.Joining multiple images together to form 1 single .jpg image

Hi Onur,

Thank you very much for the working code!  It works like a charm.  Now
my next step is to give support for more than 2 images and add a nice
GUI! Thanks for setting me on my way!
