Re: Export Symbols - Win32 DLL project with VisualStudio 2005

it's actually to do with exporting debugging symbols, have you tried debugging both versions of the dll ?

Ignore both my previous comments - I think the setting actually creates a file called <projectname>.h which contains the __declspec(dllexport) declarations so that you can export from the DLL.

Both "Export symbols" checked and unchecked projects have the same declarations in "ProjectName.h"s.

#ifdef EXP_EXPORTS
#define EXP_API __declspec(dllexport)
#else
#define EXP_API __declspec(dllimport)
#endif

And EXP_EXPORTS is defined in the preprocessor definition setting.

I am using visual studio .net 2003 and get the results I mentioned earlier, I guess it may be different in 2005 but I cannot find any information on the setting.

Hi,

I am creating a Win32 DLL, using VS.NET. I build the project and want to use functions from dll, but i am wondering where is the .lib file. the dll file is there in debug folder of project.

any pointer will be helpful

Thanks in advance

there may not be one, a dll is a dynamic library and a lib is a static library.

also a .lib file can be a type library for a .dll

Abhi Lahare11-Jul-06 23:19

1)how can we confirm that it do not generate any lib file?
2)Whether that means you cannot statically link?

1) If there is no .lib file after you compile then it is not being generated
2) You cannot statically link to a dll (or at least not easily)

When you create the project for a DLL, you can specify whether you want to produce the .lib file too (export symbols checkbox) but i can't remember how you modify an existing project to do this.

see Property Pages / Configuration Properties / Linker / Advanced. put the path to the file you want to create in the field labeled "Import Library" (ex. "./Debug/MyDLL.lib")

The word "multi." They both imply more than one thread.

Hi All,
Can someone provide a good link that relates to the designing and development of code for creating efficient user interfaces.(Only Win32)
I tried googling for the same without any satisfactory results.
Some good articles on codeproject or some where else.

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

Sometimes it difficult to define efficent. i have experienced in many cases where i have to change the efficent UI( from functional and user point of view), but customer does'nt need that UI.
I know it sound silly, but just designed what customer wants Smile | :)

In your .h file
you must have deleted the enum

something like this
// Dialog Data
enum { IDD = IDD_MYAPP_DIALOG };

where IDD_MYAPP_DIALOG is a dialog box template
