Displaying in image file

Hi everyone,

I am interested in making a program to display an image in a window. I have tried using a resource file before, but that method just compiled the image into the program, meaning that if I changed the image at all, the changes wouldn't be displayed in the program unless I re-compiled it. Does anyone know how I would get around this? How do I make a program read an image file from my hard disk every time it runs, so that if the image is changed, the changes will be visible when you run the program?

Thanks.

...Failing that, is it possible to open an image using the Windows Picture and Fax viewer with C++?

It is possible to display an image on a window. Which library you use?
It can be as simple as:

Code:

---

Window w = new Window();
...
w.Background = new Image("C:\\Pictures\\Dumdum.jpeg");

I am using the default Win32 with VC++ 2008. I also found out how to open the image with Picture and Faxt viewer, but your method sounds nicer :)

I think you are tainted with C#...

Invariably, how you are going to do it will vary with what GUI library you use and possible what imagine library, if any, you use.

I said it "can be simple as..."
If you are using a library I don't think it will be more complicated than that. There is usually an Image object of any kind. Similar, a Window object of any kind, or any kind of user interactive/non-interactive control will usually let you alter its background. If you combine those two you can view an image.

In C# or in .NET in general the recommended would be to use an already built control for this, like a PictureBox. But my point is that you don't need an external program or a special control, since the functionality of altering a windows background image and the ability to have an already built in object for image are really basic.

Like I said, you are tainted.
It is rarely as easy as you describe. Not because it cannot be, but because there is rarely such quality written C++ code to be found in the first place. That's probably because people are ignorant.

Furthermore, you use new when absolutely unnecessary and you try to assign to a non-pointer. Again, C# taint.
