I want to antomaticly start my program when the user double clicked the file

The file is specific to my program,how should i do ?

If you're doing a document/view structured program you can associate the file to the program.

Firstly, you'll need to change the resource for the document specifying file type etc :

This is in the string tables e.g. if the extension is .map

Code:

---

IDR_MAINFRAME

My Application\n\nMAP\nMy Application files (*.map)\n.map\nMyApplication.Document\nMy Application Document

---

Then insert the following two lines into the InitInstance of your application class after AddDocTemplate :

Code:

---

EnableShellOpen();
RegisterShellFileTypes(TRUE);

---

That should do the trick. This will associate whatever extension with your application and your application will fire up and open a file when it is double clicked.

Thank you ,but my program is dialog based,how should i do?

You can do the same for your dialogbased application .
Use the following

void CYourApp::RegisterShellFileTypes(BOOL bCompat)
{
CWinApp::EnableShellOpen();
CWinApp::RegisterShellFileTypes(bCompat);//TRUE

}
