[wix-users] calling 3rd part library calls using custom action in c++

[Hanumanthaiah, ShashikalaX]

Hi,

    I have created a DLL which just creates a file. Iam trying call this Createnewfile API through custom action in wix cpp.
    My compilation went fine but when I run the msi , The file is not getting created after the installation. Iam attaching the snippet for reference.
   Could you please guide me where Iam going wrong .

   Custionaction.cpp
#include "Testdll.h"

UINT __stdcall Createfile(
       MSIHANDLE hInstall
       )
{
       HRESULT hr = S_OK;
       UINT er = ERROR_SUCCESS;

       hr = WcaInitialize(hInstall, "Createfile");
       ExitOnFailure(hr, "Failed to initialize");

       //const char* filepath="C://shashi.txt";
       //const char * Mode = "W";
       //wsprintfA(filepath, "%S",L"Name");
       //wsprintfA(Mode, "%S", L"Name");
       //LPWSTR filepath;
       //LPWSTR Mode;

//hr = WcaGetProperty(L"Name", &filepath);
//hr = WcaGetProperty(L"Mode", &Mode);
       WcaLog(LOGMSG_STANDARD, "Initialized.");
       Createnewfile("C://shashi.txt", "w");

       // TODO: Add your custom action code here.


LExit:
       er = SUCCEEDED(hr) ? ERROR_SUCCESS : ERROR_INSTALL_FAILURE;
       return WcaFinalize(er);
}
