Hi
I am getting NULL value in pThumbnail
Bitmap* pThumbnail = static_cast<bitmap*>(img.GetThumbnailImage(THUMBNAIL_WIDTH, THUMBNAIL_HEIGHT, NULL, NULL));
because of which i am not able to proceed further.
When i checked in Bitmap constructor
Bitmap img(A2W(strPath)) ;
The "lastresult" variable in that constructor is showing "gdpiNotInitialized"
Can anybody help in this regard

GDI+ inititialize is needed.
ULONG_PTR m_gdiplusToken;
// initialize GDI+
GdiplusStartupInput gdiplusStartupInput;
GdiplusStartup(&m_gdiplusToken, &gdiplusStartupInput, NULL);
...
process..
...
// release GDI+ resource
GdiplusShutdown(m_gdiplusToken);

Could you please send me the Updated Version (the one that allows other image formats using GDI+). It would be much appreciated. Thanks!

Why don't you just change it to use GDI+ ?

Hello!
Your exemple is ok, but the thumbnail images from the list are very unclear.
Can I set these images to be more clear/sharp - something like add more contrast, similar with Windows Explorer thumbnail icon? I'm not use picture big screen preview, just the thumbnail list!
Any ideea will be apreciate!

Does anyone know where I can find and example similar to this in which other image formats can be added to an image list? I have searched codeproject, codeguru and other similar sites and have not found an example

I have sent you an updated code for this project to your E-mail address. That version supports various image format by using GDI+.
|
|
|
|
|
Do you have a version that works with visual c++ 6.0? If you do not I will try to convert the project to 6.0.

The second parameter of Insertitem() function is the item's label. By passing that a NULL or TEXT(""), you will achieve the effect.

I'll post a updated version of the code that uses GDI+. That will allow you to open images with any format that GDI+ can handle.

Hi,
Can you help me? I would like a web address or code except demonstrating "how to" dynamically open a window bitmap file and insert into a CImageList object and then use the CListCtrl box to display the bitmap in a report view. I want to do something similar to your program... but I want the images to be in the first column of a report (CListCtrl view) and descriptive text in the second column. I do not want to use pre-compiled file names, as a resource IDs. The bitmap files are 140 x 70 pixels. The CImageList::Add function requires a CBitmap*... but the CBitmap class does not allow you to easily open a bitmap file. If you can't help me with the above, then please answers the following question: do I need to use your "dib" class and the windows blits function API, or is there a simple MFC approach... since bitmap files are so common to Windows programming ??
Thx,
King

You need to open the bitmap files one by one to get the height, width, bitcount, and bitmap data of your bitmaps. Then, call the "CreateBitmap" member function of the CBitmap class to create/populate CBitmap objects. Once you have the CBitmap objects, you can add them to your image list. When you insert items in your report view, make sure you initialize the LVITEM structure to include your image list items.
You do not have to use any bitmap class to load a bitmap file. search through the MSDN, there are a lot of examples to show you how to open and load bitmap from file.

could you please send me the code for further study?

thank you.

Does your code allow one to display large thumbnails (say 100 x 100 pixels bitmap images) in the list control? It seems from MSDN documentation that one can only display 32 x 32 pixels images in the list control but may be that's my misunderstanding.
|
|
|
|
|
Yes. The thumbnails in this code is 100x75
|

Hi,
So, if I want to modify the size, like if i want to show preview for 200 X 200 will it be possible ?
