Question:
How can I delete my executable while it is running?
Answer:
Under Win32, unless you are running from a removable drive, you
cannot delete a running executable. You can have Windows delete the
executable the next time Windows is run by adding an entry to the
RunOnce key in the Windows registry under:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can name the key anything you like, and specify a command line to
another executable or to a dos command passed to command.com.
Example:
void __fastcall TForm1::Button1Click(TObject *Sender)
{
TRegistry* reg = new TRegistry;
reg->RootKey = HKEY_LOCAL_MACHINE;
reg->LazyWrite = false;
reg->OpenKey("Software\\Microsoft\\Windows\\CurrentVersion\\RunOnce",
false);
reg->WriteString("Delete Me!","command.com /c del FILENAME.EXT");
reg->CloseKey();
reg->Free();
}
