Image List

Recommended Posts

the problem I'm having is that I cant add a jpg image to an image list :x and I'd love to know how, first off I'v writen a script to copy images from one place to another and once its done I want to display a preview of all the images in my gui along with there title, the amount of images can vary from 1 to 20 so it wont always fit in the gui and I want to put it into a list, also due to the fact that I'm copying from one place to another (preserving the file type) I cant change the images to bmp because of why I'm copying the images. note this works fine when I'v changed the image to a bmp but not as a jpg, I have also tried using GDIp to load the image and convert it into a bmp but I didnt know what I was doing so if someone could show me what too do that would be great, thanks

Perfect thanks Yashied, and this will work the same in xp as it does in 7 and vista? also what would I need to change to have white bars instead of black on the top and bottom of my image preview? if thats not possible thats fine.

The code works for me in Windows XP Pro SP3, but I don't know if it works "the same" without seeing how it works in Vista/7.

I don't see any black bars, but trying changing this line from this:

_GDIPlus_GraphicsClear($hGraphic, 0)
to this.

_GDIPlus_GraphicsClear($hGraphic, 0xFFFFFFFF)
perfect, I looked for a color code like that but didnt see any and I didnt know what graphicsclear meant, thanks Deathbringer

so I'v been using the code posted for a while, and it works great but the only problem is now that I cant remove items and images from the list :x here is some of the code

;code to create the lists in the first place
Global $ListView1 = GUICtrlCreateListView( "", 5, 80, 409, 242)
$ImageList1 = _GUIImageList_Create(150, 150, 5, 1)
_GUICtrlListView_SetImageList($listview1, $ImageList1, 1)
_GUICtrlListView_AddColumn($listview1, "Images", 240)

;code to add images and there items
_GUICtrlListView_AddItem($ListView1, $fileName, _GUIImageList_AddImage($fileName))

I found if I create the listview with "_GUICtrlListView_Create" and not the normal I can remove items, (using "_GUICtrlListView_DeleteAllItems") except I cant figure out how to force the list to only display on the tab I want it too, (my gui has a tab design) so I use the normal way to create a listview but I cant figure out how to remove all the items from the list so I can add some more later.
