Re: is this group not work now days?

Tech-Archive recommends: Speed Up your PC by fixing your registry

I can't see where! In the event procedures you are converting from device
to logical coordinates. Then for all other operations you are using the
logical coordinates, also with CreateCompatibleBitmap() and BitBlt().
LPtoDP() is declared in your code but not used anywhere!

CreateCompatibleBitmap() i used int MakeMDC function
and BitBlt(). i have use in UpdateDC Function
Yes LPtoDP is just declared for future use.

In addition:
- The map mode of the source and destination device contexts used with
BitBlt() differ; I am not sure if this is supported by BitBlt().

Yes it support.

- You shouldn't store the device context handle retrieved with GetDC() in
your DC structure for the device context handle may change. Instead use
GetDC() instead of '.pDC'.

if you debug. you can see handle is there.


And like Olaf I realy don't have any idea what this is all about...
