Hi,
I am facing a problem.I have to load images in any format and display them as contact photo of users,where in this function OleLoadPicturePath() doesn't accept .png images. My basic need is to attach a PNG image to a imagelist which is used to load that image.Since Im not using CImage,best way which I got from browsing is to Convert that PNG to a Bitmap and attach this to the imagelist.Can anyone please tell me how I can go ahead with this??Thanks in advance.

Solution 2

What would you probably do?

If this way is bad :

CImage image;
image.Load(_T("C:\\myimage.png"));
CBitmap bitmap;
bitmap.Attach(image.Detach());

So, try following way:
An MFC picture control to dynamically show pictures in a dialog[^]

Solution 1

Show some code or what is the error? Compressed png arent supported, so you need something else.

I recommand this article for image issues:

Load the PNG with CreateIconFromResourceEx then add that icon to your imagelist.

HICON LoadIconPNG(LPCTSTR lpFileName, INT nWidth, INT nHeight)
{
	HICON	hIcon = NULL;
	HANDLE	hFile;
	DWORD	dwsz, dwbr;
	BYTE	*pb;
	if ((hFile = CreateFile(lpFileName, GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, 0, NULL)) == INVALID_HANDLE_VALUE) return (NULL);
	dwsz = GetFileSize(hFile, NULL);
	pb = (BYTE *) malloc(sizeof(BYTE) * dwsz);
	if (!ReadFile(hFile, pb, dwsz, &dwbr, NULL)) { free(pb); CloseHandle(hFile); return (NULL); }
	CloseHandle(hFile);
	hIcon = CreateIconFromResourceEx(pb, dwsz, TRUE, 0x00030000, 0, 0, LR_DEFAULTCOLOR);	
	free(pb);
	return (hIcon);
}
