Re: "Unresolved External" error in object declaration

Yes, it is. I forget to say I'm using Microsoft Visual Studio 2008 and both .cpp and .h files are present in the project. Also alist.h is included.
When I remove template from the class and replace it properly with int, it works fine. So I don't think the problem is related to that.

Check whether AList.h and AList.cpp files are added to the project. Take Workspace window and check in the FileView tab. If its not added, add by taking menu, Project -> Add to Project -> Files.

If the cpp file is not added to project, it will not be considered for compiling and corresponding .obj file will not be created. Finally linker could not find the definitions for corresponding class.

Jijo.

I've checked files before, their fine. When I remove template from the class and replace it properly with int, it works fine. So I don't think the problem is related to that. (Like what I said for the previous question)

Thanks anyway.

Doxygen?

This is admittedly a sort of meta question but does anyone know if the Doxygen list is down or the moderator on vacation? It has been more than 48 hours and nothing has gotten through the moderation barrier. I'm wondering if anyone is home?

p.s. and now back to your regular programming...

Why "reinvent the wheel" when you can use a library? Confused | :confused:

I don't know about tutorials, but it generally comes
down to looking up the published file format and parsing the
file appropriately.

Examples:
BMP[^]
PNG[^]
TGA[^]
RAW = Google "RAW file format"...there's lots of raw formats.

You can also use GDI+ for loading images. Here are some examples:

http://www.codeproject.com/KB/cpp/GDI_.aspx[^]

http://www.codeproject.com/KB/GDI-plus/GdiPThumbnailsViewer.aspx[^]

If you don't want to use GDI+, than you can try CxImage library:

http://www.codeproject.com/KB/graphics/cximage.aspx[^]

It's really very cool library that can help you to get information about loading images.

For bmp,png,gif,jpeg and I think tiff you can use of CImage class But onthe codeproject you can see CXImage article is very helpful for you.

By Using Mapping modes how to draw points in a rectangle?

pallaka22-Aug-08 4:52

Hi,
I am having a rectangle.
I need to create a graph by setting x axis -80 to 80 and y axis -80 to 80.
Means the BottomLeft of the rectangle will be (-80,-80); and top will be (80,80).
By using mapping modes MM_ANISTROPIC.
I need to draw a point if suppose a point is (-75,60).
Then the point should be drawn in the rectangle.

Thanks in advance.
