in my application wich uses the ActiveX-Control with MS-Access/vba. I have to load about 50 Geo-Tiffs (each about 70 MB) which is painfully slow. I use the folowing code:
objImage.Open(strIPath & strIName, USE_FILE_EXTENSION, True)
Is there any possibility to speed this up? Or is it possible to load the pictures only of a given window, when zoomed to it - and if so is there an example code?
I overcame this problem by writing a small routine with which I calculate the coordinates of a click and load the apropriate image - which is quite easy for the image-names contain their coordinates.
The problem I now have is that the pictures are displayed on top of the drawing but they should lie behind. How can I change this?
