Alphachannel-Bitmaps in Shortcutbar

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi,

I use a shortcutbar inside of a dockinpanel (version 11.2.1).
The bitmaps of the shortcutbar are 32Bit-BMP-Files with alphachannel and they are displayed correct. But if I start the program on a terminal server or by remote desktop connection they are not shown.

PNG-files are never shown. Using 24Bit-BMP-Files without alphachannel and defining the maskcolor for the transparent color works fine (remote, too), but it would be better for me, if I could use alphachannel-bitmaps so I don't have to change all of the bitmaps.

Regards,

Rene

	Hi, we use DataFlex. It works different than vb.net for example. But I think, you will understand this example. External_Function LoadImage "LoadImageA" User32.dll ; Integer hInst String sImage Integer iType Integer cx Integer cy Integer iFlags Returns Handle move (LoadImage (GetModuleHandle (0), "SC_NVKUND.BMP", IMAGE_BITMAP,0, 0, 0)) to hBitmap send ComAddBitmap of hoImageManager hBitmap C_BITMAP_SC_NVKUND xtpImageNormal true

	Hi, LoadImage can fail. Use Icons.LoadBitmap or Icons.LoadBitmapFromResource method to load alpha bitmap instead of LoadImage.

	Ok, I tried it with LoadBitmap, but the bitmap isn't loaded. send ComLoadBitmap of hoImageManager "h:\xap7\bitmaps\SC_NVKUNDV.BMP" C_BITMAP_SC_NVOBJEKT XTPImageNormal hoImageManager is a child-object from the shortcutbar from class cCJImageManagerIcons. Because I haven't a resource, I can't trie LoadBitmapFromResource. Very interesting is, that LoadImage/AddBitmap works fine, until I start the program from another computer by remote desktop. That's, what confuse me.

	Your code "LoadImage (GetModuleHandle (0), "SC_NVKUND.BMP", IMAGE_BITMAP,0, 0, 0)) to hBitmap" seems load image from resource - not from file. another option is add ImageManager object from CommandBars package, add images in designtime and assign them to ShortcutBar: .Icons = ImageManager.Icons
