Open With Program...

[Shay9999]

Just going to ask this since I'm 85% dead inside right now ^_^

When you right click a file in Windows Explorer, you can open it with a program (open with...). How would I write that in a program?

Let's say, turning this "example.txt" into whatever the user opened the file/program with:

  ofstream File_A;
  File_A.open ("example.txt");
  File_A<< "This file sucks.";
  File_A.close();

I'm thinking there's a few lines of code out there that go:

  string FName = Windows.fileName;
  string FLoc = Windows.fileLoc;

but I'm probably wrong.

There is SHOpenWithDialog() function, but it is only available in Windows Vista or later.

I'm having a problem with this, I'm getting several errors and I think it's because I'm not using the right libs, or maybe I'm just stupid... Mind taking a looking and giving me some feedback?

#include <windows.h>

int main()
{
    OPENASINFO Info = { 0 };
    Info.oaifInFlags = OAIF_EXEC | OAIF_ALLOW_REGISTRATION;
    SHOpenWithDialog(NULL, &amp;Info);
}

You are not passing any filename. How can the dialog box know what file it should refer to? You must provide the file's name.

Now I'm getting the error:

5 C:\CPlusPlus\OpenDialog.cpp `OPENASINFO' undeclared (first use this function)


Also, I changed the code to:

#include <windows.h>

int main()
{
    OPENASINFO Info = { 0 };
    Info.pcszFile = L"C:\\CPlusPlus\\OpenDialog.cpp";
    Info.pcszClass = NULL;
    Info.oaifInFlags = OAIF_ALLOW_REGISTRATION;
    SHOpenWithDialog(NULL, &amp;Info);
}

MSDN Online is your friend. http://msdn.microsoft.com/en-us/library/windows/desktop/bb762234(v=vs.85).aspx

In there you'll see which header you must include, and which lib you need to include to link your project.
