I have a custom icon in my CXTPTaskDialog (not using Vista API). When I set WINVER=0x0500 the icon is drawn a la Windows 2000. The borders become jagged (i.e. no alpha blending). Note that I have included the needed manifest!
I believe your dialog uses the native icon drawing functions. This causes a problem in the above scenario. ------------- PokerMemento - http://www.pokermemento.com/ |

The icon is loaded via this call: LoadImage (NULL, pFileName, IMAGE_ICON, cxIcon, cyIcon, flags); Hmm, is this the root cause?------------- PokerMemento - http://www.pokermemento.com/ |

Hi, We have standard DrawIconEx API call to draw it. so problem can be only in icon or way you load it. Try add LR_CREATEDIBSECTION flag. ------------- Oleg, Support Team CODEJOCK SOFTWARE SOLUTIONS |

This is really strange. I don't think this has to do with CJ.
If I load ico-files with this API, and then put them in your toolbars, the alpha layer seems to be lost!

This worked a couple of months ago. Since then I've upgraded from 12.1.1 to 13.0.0. Perhaps MS updated a vital DLL somewhere? Don't get it...
Could you please try this?
HICON hIcon = NULL;
UINT iconID = 0; if (PrivateExtractIcons("C:\\WINDOWS\\notepad.exe", 0, 16, 16, &hIcon, &iconID, 1, LR_COLOR)) { iconID = XTPImageManager()->AddCustomIcon(hIcon); pButton->SetIconId(iconID); DestroyIcon(hIcon); } The resulting image is screwed at the borders...  ------------- PokerMemento - http://www.pokermemento.com/ |

It's just like ComCtl32.dll v5.8 was being used... I don't get it! My code worked a couple of months ago... Clearly, the manifest is not included in your dll. Just made a search for the public key token: 6595b64144ccf1df Not found?------------- PokerMemento - http://www.pokermemento.com/ |

Hi,
It have to be included to your exe - not to our dll. ------------- Oleg, Support Team CODEJOCK SOFTWARE SOLUTIONS |

Hi,
Just tried with CustomThemes sample
HICON hIcon = NULL;
UINT iconID = 0; if (ExtractIconEx("C:\\WINDOWS\\notepad.exe", 0, 0,&hIcon, 1)) { XTPImageManager()->SetIcon(hIcon, ID_FILE_OPEN); DestroyIcon(hIcon); } Works well. ------------- Oleg, Support Team CODEJOCK SOFTWARE SOLUTIONS |

Ok, but in my application the error is so obvious:
I load the icon and put it in my ribbon, and it looks great! Then, I use the same HICON in a CXTPTaskDialog and it gets an ugly border.
Either it has been scaled, or it is drawn incorrectly!
32x32 pixels...
This is a fact. ------------- PokerMemento - http://www.pokermemento.com/ |

Sorry for bothering you :P. It turned out my stupid icon was loaded as 48x48, which caused a resize...
Argh!
Anyway, thanks for your assistance! ------------- PokerMemento - http://www.pokermemento.com/ |
