You can use the argument to pass as a parameter to ShellExecute or CreateProcess.
how do you give the command and to whom...

1) Parse the commandline and get ip address as suggested by _AnShUmAn_.

2) For setting static ip by using netsh command, Please refer this link - http://support.microsoft.com/kb/257748[^]

3) For executing netsh command from your C++ code, use ShellExecute() api. Check its documentation here - http://msdn.microsoft.com/en-us/library/bb762153(VS.85).aspx[^]

Writing a hook isn't very easy. Why don't you just check every 100 milliseconds if Internet Explorer opened after this app closed and then close it.

It seems that you are right, i dumped the lib and exp files, and they all show functions from the CxImage library (which is included in the project). How do I fix it?

I guess this class must be imported instead of exported since IMO it's an external library which you are using. You might have defined some macros which you shouldn't.

Let me guess!

#if defined _EXPORT_FROM_DLL
  #define EXPORT_IMPORT __declspec(dllexport)
#else
  #define EXPORT_IMPORT __declspec(dllimport)
#endif

class EXPORT_IMPORT CxImage
{
   // Some code...
}

So somewhere _EXPORT_FROM_DLL is getting defined which forces an export.

I found very similar constructs in one of the headers in the CxImage library. I have _AFXDLL defined because the project uses MFC as a shared dll. So should I just remove the condition?

#if defined(_AFXDLL)||defined(_USRDLL)
 #define DLL_EXP __declspec(dllexport)
#elif defined(_MSC_VER)&&(_MSC_VER<1200)
 #define DLL_EXP __declspec(dllimport)
#else
 #define DLL_EXP
#endif

...

class DLL_EXP CxFile
{
   ...
};

I am not sure of this line since VC6 has _MSC_VER set to 1200 so will this code ever expand to __declspec(dllimport)?

I don't think so either, but I defined it explicitly to see what happens

// #if defined(_AFXDLL)||defined(_USRDLL)
//  #define DLL_EXP __declspec(dllexport)
// #elif defined(_MSC_VER)&&(_MSC_VER<1200)
//  #define DLL_EXP __declspec(dllimport)
// #else
//  #define DLL_EXP
// #endif
#define DLL_EXP __declspec(dllimport)

, and there are several errors and warnings:

Linking...

...

Error executing link.exe.

MyProject.exe - 8 error(s), 25 warning(s)

I also tried with defining it to nothing:

//  #define DLL_EXP __declspec(dllexport)
// #elif defined(_MSC_VER)&&(_MSC_VER<1200)
//  #define DLL_EXP __declspec(dllimport)
// #else
//  #define DLL_EXP
// #endif
#define DLL_EXP

and it still creates an exp and lib files, with the same export symbols. I really don't get it Confused | :confused:

By the way how are you using CxImage library. Have you included the entire source code into your project or are you dynamically/statically linking to it as a dll/lib?

I am asking these because the linker says it's a local symbol.

And this is what MSDN has to say on this warning...

The symbol was both exported from and imported to the program.<br />
<br />
This warning is generated by the linker when you declare a symbol by using the __declspec(dllexport) storage-class attribute in one object file and reference it by using the __declspec(dllimport) attribute in another.<br />

It's a statically linked library - no dll or cpp files, only headers and lib files.

Then the library is compiled badly. When it is compiled into a static library, make sure that no __declspec(dll{import,export}) is used. Smile | :)

The library came with the code of one of my colleagues, we checked and it seems he has compiled it with dllexport. He'll recompile it when he has time (probably tomorrow).

Well, case closed Smile | :)

Thanks for the help everyone. Poke tongue | ;-P

May be you've explicitly specified to generate lib file in your linker settings.

Take the linker settings and check for this /implib switch. For instance most probably like - "/implib:"Debug/YourLib.lib". Just remove it and problem will be solved.

Jijo.
