Problem associating file types, that doesn't exist already, with my app

[asger_gronnow]

Hi
I'm having trouble associating file types with my app. Associating a
file type works as long as the file type is already associated with
another program but if the file type doesn't exist already, it isn't
associated. So my question is: how do I associate a file type that
isn't registered already? How can I register this new file type if
that's what I'll have to do before associating it.
I'm programming in Win32 using the Dev-Cpp compiler. Here's the code I
currently use to associate file types:

void associatefile (string filetype)
{
HKEY hKey;
string exepath=AppPath ;
string key = "LibertyExpress ";
string keyval = "LibertyExpress ";

int reg = RegCreateKey( HKEY_CLASSES_RO OT, key.c_str(),&hK ey);
if (reg == ERROR_SUCCESS) {reg=RegSetValu e(hKey, "", REG_SZ,
keyval.c_str(), 0);}
else {return;}

if(reg == ERROR_SUCCESS)
{
key=filetype;
keyval="Liberty Express";
reg=RegCreateKe y(HKEY_CLASSES_ ROOT, key.c_str(),
&hKey);
if(reg == ERROR_SUCCESS)
{
reg=RegSetValue (hKey, "", REG_SZ,
keyval.c_str(), 0);
if(reg == ERROR_SUCCESS)
{
key="LibertyExp ress";
keyval=exepath+ " %1";
reg=RegCreateKe y(HKEY_CLASSES_ ROOT,
key.c_str(), &hKey);
if(reg == ERROR_SUCCESS)
{reg=RegSetValu e(hKey, "shell\\open\\c ommand", REG_SZ, keyval.c_str(),
MAX_PATH);}
}
}
}
}
