Create image buffer with dll function

[andreas_p]

Hi,

I have a usb barcode scanner which I control with a bunch of functions in a dll file. I used the wizard which was pretty straightforward. Now I can send most of the commands I want but have a slight problem when initializing image mode. There is a createimagebuffer function but it wants a string input, "a pointer to the destination buffer for image data returned from the scanner". What am I suppose to point at and how do I do it? Im new to this (first time experimenting with dll files) so I may have missed something important.

Regards

It should point to a string. The string should be large enough, e.g. it
should have a lot of characters in it. If the function also has a length
input, you can configure the dll so that the string length is automatically
linked to that input.
