[RESOLVED] Switch Statement Generate Error

Switch Statement Generate Error

:not all code paths return a value



public string DentMode(string RecMode,int ButtNo)
{
switch(ButtNo)
{
case 1:
Toolbarx.Buttons[1].Enabled = false;
return "A";
case 2:
Toolbarx.Buttons[2].Enabled = false;
codeFld.Enabled = false;
codeFld.Focus();
return "E";
case 3:
Toolbarx.Buttons[3].Enabled = false;
codeFld.Enabled = false;
return "D";
case 5:
Toolbarx.Buttons[1].Enabled = true;
Toolbarx.Buttons[2].Enabled = true;
Toolbarx.Buttons[3].Enabled = true;
return "";
}

if 1,2,3,5 is not the value OF bUTTnO then the return statement won't get executed.

Code:

---

public string DentMode(string RecMode,int ButtNo)
{
 string ret="";
switch(ButtNo)
{
case 1:
  Toolbarx.Buttons[1].Enabled = false;
  ret "A";
  break;
case 2:
  Toolbarx.Buttons[2].Enabled = false;
  codeFld.Enabled = false;
  codeFld.Focus();
  ret "E";
  break;
case 3:
  Toolbarx.Buttons[3].Enabled = false;
  codeFld.Enabled = false;
  ret "D";
  break;
case 5:
  Toolbarx.Buttons[1].Enabled = true;
  Toolbarx.Buttons[2].Enabled = true;
  Toolbarx.Buttons[3].Enabled = true;
  ret "";
  break;
}

return ret;
}
