Hello everyone,

I am using Visual Studio 2003. If I build a static library (.lib), how can I input dependent .dll (other dynamic link libraries) and .lib (other static link libraries)?

Currently, from project Property Page, there is no "linker" item, which allows us to provide dependent input .dll and .lib files when we use to build regular exe or dll project.

Could any help please?

thanks in advance,
George

In the static library linker doesn't put code for other libraries. You must use all libraries when building a executable or dll.

Thank you Saurabh!

Do you mean we do not need to provide input library information (.dll and .lib) when we build a static library?

We only need to provide header file (.h) information, right?

Why we need not provide such information (input library information) -- what is the internal reason from linker point of view?

regards,
George

For static library you need headers as well as cpp files.

Static library do not contain executable code thus there is no need to supply input libraries. This information is needed later on when you will be using this static library to build an exe or dll file.

For example suppose you have following libraries :
StaticLib1.lib
StaticLib2.lib
DllLib.lib

and you are builing a static library (StaticLib3.lib) using them. Since static library do not have executable code there is no point putting information from input libraries into StaticLib3.lib.

Now suppose you want to build an exe using StaticLib3.lib. At this point you will need StaticLib1.lib, StaticLib2.lib, DllLib.lib, and StaticLib3.lib.

Hope this clear things up.

Thank you Saurabh!

Your reply is great! I have a further question, can I build a static library based (dependent) on another static library?

If I can, I think I need to input the name of the dependent .lib file (dependent static library file name) to the static library, right? But in Visual Studio 2003, there is no way to add such input when build a static library.

George

Read the data from the file and write to temproary file.
Delete the file you were reading the data from.
Rename the temproary file.

Somethings seem HARD to do, until we know how to do them.

Probably the second time the CString objects contain the same values as for the first time. You should check if the CString data really contain information you expect before writting to file.

how to get font information?

Do you have error checking in place?

CString str;          // or whatever you have
CFile pFile;
CFileException ex;    // add exception handling
char szError[255];    // add msg buffer

if( !pFile.Open(szFile, CFile::modeCreate|CFile::modeWrite, &ex) )
{
   ex.GetErrorMessage(szError, 255, NULL);
   AfxMessageBox("File Error: " + szError, MB_OK|MB_ICONERROR);
   return;   // or return FALSE;
}

if( !str.IsEmpty() )  // always check for data!
{ 
  // Now write the data to file...
  pFile.Write((LPCTSTR)str, str.GetLength());
}

// close
pFile.Close();

I have a truetype font file, named "LSANSI.TTF" but which if i open is shown as Lucida Sans Italic and windows also displays it correctly as Lucida Sans Italic instead of showing it as LSANSI.TTF

How do I get this "Lucida Sans Italic" information from the font file? Is there any api call like GetFontName() or anything similar?

-Use CreateFontIndirect method to create with facename "Lucida Sans Italic"
-Select the font into device context
-Use GetTextMetrices method to get the current text Metric
-The structure contains information about your selected font.

But what if you used "My Favorite Font" instead? Would GetTextMetric() still report the font as "Lucida Sans Italic" or would it be "My Favorite Font" instead?

Where?

What part of the TEXTMETRIC structure do you propose the font's facename come from?

It is used to get information of the known font only.
You have to specify the font face name to get information of the font.

does visual studio 2005 support earlier vc++6.0 MFC projects?

Use GetTextFace().

If, however, you don't actually need/want to "load" the font, use EnumFontFamiliesEx().

Visual Studio 2005 supports VC++ 6.0 MFC. But once you convert to Visual studio 2005 version you cannot run it again VC++ 6.0.

Visual Studion 2005 does not provide that backward compatibility.

Opening a VC++ v6 project with VS 2005 will cause it to be converted. Is that what you meant?

I'v download a the visual studio 2005 express editions from microsoft homepage.but there seems no MFC resource.

Opening a VC++ v6 project with VS 2005 cause it to be converted. while build the project in vs2005, the error occurs.
information is all of the follow files cann't be found. and the MFC resources cann't be found.
#include <afxwin.h> // MFC core and standard components
#include <afxext.h> // MFC extensions
#include <afxdisp.h> // MFC Automation classes
#include <afxdtctl.h> // MFC support for Internet Explorer 4 Common Controls

I found on microsoft homepage that vs 2005 express editions doesn't support MFC. but I want to know the other Version such as VS 2005 standard edition and vs 2005 professional edition can support MFC?
