Hi aecspades23
Thanks for sharing your efforts.
I am in the same boat as I am also not able to see the content of chm files through my application if access across network drive.
OS - Windows 10, 64-bit
I can see the contents of chm file across network when I double click on it just by modifying only this entry in the Registry:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
"MaxAllowedZone"=dword:00000002
I have neither modified HHRestrictions nor added UrlAllowedList in the registry. When I run my application with above manual registry changes across the network, I am still able to see the contents of chm file and that's what I want.
I want to make the above manual change in Registry programatically when I run my application. I have written the C++ function for that but somehow its not modifying the Registry value. Below is the function:
ModifyRegistry(HKEY hk, const wchar_t *key, const wchar_t *name, int *val, DWORD type )
{
DWORD rtn=0;
HKEY KEY;
LONG phkRTN;
phkRTN = RegCreateKeyEx(hk, key, (DWORD)0, NULL, 0, KEY_WRITE, NULL, &KEY, &rtn);
if( phkRTN == ERROR_SUCCESS )
{
if(type == REG_DWORD )
{
DWORD *i = (DWORD*)val;
RegSetValueEx( KEY, name, 0, type, (LPBYTE)i, sizeof(DWORD) );
}
}
RegCloseKey(KEY);
return(rtn);
}
where
hk = HKEY_LOCAL_MACHINE
key = L"SOFTWARE\\Microsoft\\HTMLHelp\\1.x\\ItssRestrictions"
name = L"MaxAllowedZone"
*val = 2
type = REG_DWORD
I have debugged and checked the returned value of RegSetValueEx and its coming ERROR_SUCCESS.
Do you or someone have any idea whether I am missing anything here or some other permission is required. I am giving 6'th parameter of RegCreateKeyEx function as KEY_WRITE which is the combination of
STANDARD_RIGHTS_WRITE | KEY_SET_VALUE | KEY_CREATE_SUB_KEY) & (~SYNCHRONIZE))
In some of the blogs I have read that we need to run the application in elevated mode which I am not aware. Can someone please let me know what that mean is or can share good links or example related to this.
