Thismay not be the proper forum for this posting so I appoligise in advance if I have got it wrong, but i am hoping that someone can help me with my problem.

The problem is that when using IM with PDFMDD11.lib (thrid party Libraries) and third party lib under VS2005 and I then try to link to the StaticMTDLL IM Libraries I am recieving link errors indicating objects already defined.

I believe that the problem is a conflict of some kind between the PDF image libraries for reading/writing TIFF, PNG, and JPEG files and the Imagemagic Libraries. Can anyone help me put with this and provide a solution if possable.

The errors read.

>log4cppD.lib(CategoryStream.obj) : warning LNK4075: ignoring
'/EDITANDCONTINUE' due to '/INCREMENTAL:NO' specification

1>CORE_DB_magick_.lib(nt-base.obj) : error LNK2005: _DllMain@12 already

defined in pdfMDD11.lib(png.obj)

1>..\..\output\Debug\Controller_win.dll : fatal error LNK1169: one or more

Options that I have tried include the /FORCE switch usage on the Linker Command line. Any solution ideas would be welcomed

Many thanks

Maybe you should add a label control (CStatic) near your progress bar, and set its text programmatically? Something like this:

CString s;
s.Format(_T("%i%%"), m_cMyProgressBar.GetPos());
m_cMyLabel.SetWindowText(s);

I hope this helps.

first of all, i told you to EDIT the existing post, to resposting again and again a huge bloc of code.

moreover, why i told you to use it? because Chris asks us to[^] (see 5.)! the code samples should be embraced by pre tags.

at last, it DOES PRESERVE the formating, but you used it wrongly.
if you want to see the empty lines, place at least a space on those lines.
and if you want to see some indentation, just put some spaces at the beginning ot your lines, and you'll see the spaces that doesn't appear in normal case...

oh, i was forgetting : when you put some #include statement, use the < and > html codes to print < >, otherwise, your include headers will be understood as html tags too.

Thanks to your advice I also noted Chris said:

But, before this gets more out of shape. I agree what you said was completly valid as far as the response protocols I employed is concerned (That won't happen again) but the way you said it did not inspire me to seek to thoroughly correct myself.

Sorry if I pressed your buttons though.

Again, this is false. This statement is true only if the function is pure virtual. You can perfectly have a virtual function in the base class which is not implemented in one or several derived classes (even not implemented at all in the derived classes).

I think you should try this:

    }
};

won't compile more. A::f() is virtual, so, not implemented...

moreover, the compilation error is no B::f() implementation overloads A::f()

You can perfectly have a virtual function that is implemented in the base class. Making it virtual doesn't mean that you cannot implement it. I think you mix it with a pure virtual function which is:

virtual void f() = 0;
