Alok give you a good link but if you are new to drag drop (I suggest before use for files see simple drags like drag a item of a list to other list) codeproject has articles about drag files.;)

Yeah for drag images of explorer to listctrls,I tried I think its easy for you each control has a option "Accept file" that you must active for control and then use of WM_DROP for actions on the ListCtrl it has a event for it that you can drag a file or files on the loop to it also you can set image when you are draging (I didnt try it)

I want to load an image to a control by downloading it at runtime. Can some body please tell me how to load the image at run time. (i need it for all types of images).

Thanks

Kishore

What image? From where?

i want to load a bitmap image from a specified location, at run time.
For example: i want to load the image from the file "bitmap1.bmp" saved on desktop to a control on the UI.

Ok, so what's the problem? What code do you have so far?

to load the bitmap file use something like :

HBITMAP hBitmap = (HBITMAP)::LoadImage(0, lpszFileName, IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE);

If you want to load bmp files you can use of LoadImage but if you want to load other files like jpg you can use of CImage class and then use of a hbitmap for set it to controls.

doesn't you think, CImage required ample amount of code and inclusion of header file to make it work in vc++.. but i believe it is one of good class provided by MS for image handlling. i believe C# also use same interface!

Yeah CImage has a header file that it gives some memory but I guess maybe he will have problem on next for jpg files so I suggest this class however he can uses of GDI+.

Search for IPictureDisp if you like using COM and search for CEnBitmap class by Dan.G. here.. that would solve your purpose! i feel

So then just use Excel Automation.

But I m not sure this could work in EVc++ 4.0.

priyank

It may not, but given that you wanted to read the file in it's native format, I know of no other solution.
