Hi,
 
LoadBitmapFromResource was added for loading alpha bitmaps.
 
use this way instead
 
UINT command = ID_2;
m_wndTaskPanel.GetImageManager()->SetIcons( IDB_DEVICE_ICON16, &command, 1, CSize(16, 16) );

Unfortunately the project is too large to attach, even when zipped.
However I attach the file the most relevant files so you can at least see what's happening.
Your suggestion that I am doing something wrong is probably right because I only started using codejock this week!

The file that contains the code which loads the images is MainFrm.cpp, line 255 where it says "Test 3".

Cheers

I loaded a 32x32 .bmp and it didn't work.

I don't know what to try now!

Cheers Jahonas,

I just tried out ur suggestions. LoadBitmapFromResource does return something and SetIcon return true.

I will try and investigate further by loading exactly a 32x32 image and see if that yield s any results.

Ugh, there was a slight error in my code, although it doesn't explain your problem. The variable "A" being passed to the function should have been "&Alpha". The HTML thought that the & symbol meant something else. I've corrected my original post. As best as I understand, that boolean is not an indication of success or failure, but of whether or not the loaded PNG uses an alpha channel.

As far as why the image doesn't display.. I'm not sure. I know that code has been working for me. Is the PNG in question actually 16x16? I'm not sure what it would do if the size you give it doesn't match the size of the image. You could check the return value of both LoadBitmapFromResource and SetIcon to see if either returns an error value. If one of them does, you could step into the loading code in the debugger to find out where and why it's failing.

If they return successful values, I'd guess there was something wrong with how the image is used in the TaskPanel, but I'm completely unfamiliar with TaskPanels, so I have no idea what that problem might be. My only wild guess would be that the TaskPanel might be looking for a 32x32 or some other sized icon to display and the ImageManager only has the 16x16 one loaded.

Good luck. :)]]> Tue, 23 Oct 2007 10:50:31 +0000 http://forum.codejock.com/forum_posts.asp?TID=8446&PID=27580&title=how-to-load-a-single-png#27580 <![CDATA[How to load a single .png? : Jayonas wrote:ImageManager...]]> http://forum.codejock.com/forum_posts.asp?TID=8446&PID=27576&title=how-to-load-a-single-png#27576 Author: poiser

You can also load them from files by using LoadBitmapFromFile instead of LoadBitmapFromResource.


I tried the following code above but modified to suit my needs (code below). It compiles and runs fine but the image/icon is not displayed.
When i checked the value of A at runtime it was false meaning that loading the .png failed. Can somebody tell me why?


UINT command2;
command2 = ID_2;
BOOL A;
m_wndTaskPanel.GetImageManager()->SetIcon(CXTPImageManagerIcon::LoadBitmapFromResource(MAKEINTRESOURCE(IDP_DEVICE_PRINT), &A), command2, CSize(16,16), xtpImageNormal);
CXTPTaskPanelGroupItem* pItem3 = pGroup->AddLinkItem(3, ID_2);


IDP_DEVICE_PRINT is defined in the .rc as follows:

IDP_DEVICE_PRINT    PNG   MOVEABLE   PURE     "C:\\Dev\\print.png"


p.s.: all suggestions are welcome!
