You should remove this code from your constructor.

That code is fine. It was the extra Create() call that was the problem. Note the assertion indicated exactly what the problem was (i.e., the window handle was non-NULL).

Why aren't you using GetTimeZoneInformation()?

Image Quality Loss on Extrating Image from CImageList

1-Aug-06 3:10

I don't quite follow you. Confused | :confused:

You wanted to know how to obtain the timezone using Visual C++. I suggested you use GetTimeZoneInformation(). Now you are talking about browsers and XML files. What exactly is it that you are looking for?

It's my recollection that you need to create an empty image list and copy the 24 bit images into it in order for them not to revert to the lower bit depth.

thnx for reply... but can you tell me how to copy the 24bin image to CimageList.. and i want to Animate the Images, but if i load one by one image into the Imagelist in Startup initailization then it takes a lot resource and thr will be lots of bitmap image files in the skin folder. like if i want to create a animation of 20 frames then user have to create the 20 images , and i think its better if we use a Image List instead of loading a Single bitmap into imagelist without lossing qualit !

please tell me a way out of this.. thnx Smile | :)

There are actually articles on this site with 24 bit images in toolbars. It would be easier for you to read one of them than for me to repost the code here.

If you want to create a 20 frame animation, you will need to load 20 images, they take up the same size in an image list as they do in a bitmap.

Can I use serialization on a RecordSet Class? To be more exact. I have a program which does all sorts of things with a database. Can I save the results of a querry in a file? And can I load them when I want?

You can derived CComboBox and use from WM_DRAWITEM
like this

void CMyCombo::DrawItem(LPDRAWITEMSTRUCT  lpDrawItem) 
{
	CDC		dc;
	CString		str;
	dc.Attach(lpDrawItem->hDC);
	CRect rect(lpDrawItem->rcItem);

...
...
	DrawIconEx(dc.GetSafeHdc(),rect.left,rect.top,
		hIcon,0, 0, 0, NULL, DI_NORMAL);

...
...
	dc.Detach();
}
