Hello everyone, I am loading a TImageList at runtime from the files in a certain directory. Each time I call ImageList1->Add(), ImageList1->Count increases by 50. Am I doing something wrong here or is this normal? Thanks for future replies. ~fakepoo Back to top Remy Lebeau (TeamB) Guest Posted: Tue Nov 28, 2006 2:28 am    Post subject: Re: ImageList count increase by 50? <fakepoo (AT) gmail (DOT) com> wrote in message news:1164659335.071859.247490 (AT) h54g2000cwb (DOT) googlegroups.com...

All I am doing is adding, one by one, .jpg files from a directory into this list. I assume that these pictures could possibly have different dimensions. As I stepped through the execution, I noticed that ImageList1->Count went from 0 to 50 to 100 to 150 and so on. I could probably use something like TList to do what I want to do so it is not a big deal.

Quote: Is that necessary? Yes. The individual images must match the Width and Height that are set for the ImageList. TImageList is just a simple wrapper around the Win32 API ImageList control, which does not support mixing images of different dimensions.

What are the Width and Height of the TImageList actually set to? When adding an image to an ImageList, the image can be split into multiple images if the dimensions do not match. Gambit Back to top Guest Posted: Tue Nov 28, 2006 7:10 pm    Post subject: Re: ImageList count increase by 50? I see. That must be what is happening. My ImageList has a width of 16 and the images have a width of 800 (50 * 16). Because of this, I will probably store these bitmaps in a different list such as TList or a data structure of my own. As for loading the JPG, I load it to a TJPEGImage then assign a new bitmap from the image. Thanks for all of the help. ~fakepoo Remy Lebeau (TeamB) wrote: Quote: fakepoo (AT) gmail (DOT) com> wrote in message news:1164662385.012119.67090 (AT) 14g2000cws (DOT) googlegroups.com...
