ReadFile Problem

[Spacetech]

Im trying to make it so I can read something out of a file and get it
into a string so I can see if It matches what IM looking for.

Here is what I got:

HANDLE hFile;
DWORD wmWritten;
char strVal[1024];
hFile =
CreateFile("settings.ini",GENERIC_READ|GENERIC_WRI TE,

0,NULL,CREATE_ALWAYS,FILE_ATTRIBUTE_NORMAL,NULL);

if(ReadFile(hFile,strVal,1024,&wmWritten,NULL) ==
"ontop=1"){
AppendMenu(hSubMenu, MF_STRING|MF_CHECKED, TOP,
"&Always On Top");
}
else if(ReadFile(hFile,strVal,1024,&wmWritten,NULL) ==
"ontop=0"){
AppendMenu(hSubMenu, MF_STRING|MF_UNCHECKED, TOP,
"&Always On Top");
}
else{
AppendMenu(hSubMenu, MF_STRING|MF_CHECKED, TOP,
"&Always On Top");
}

I got this: "error: ISO C++ forbids comparison between pointer and
integer"
I am useing Code::Blocks v1.0

Please Help

if(ReadFile(hFile,strVal,1024,&wmWritten,NULL) ==
"ontop=1"){ i think this should be the problem. The return value of ReadFile can't
compare with a string "ontop" AppendMenu(hSubMenu, MF_STRING|MF_CHECKED, TOP,
"&Always On Top");
}
else if(ReadFile(hFile,strVal,1024,&wmWritten,NULL) ==
"ontop=0"){
AppendMenu(hSubMenu, MF_STRING|MF_UNCHECKED, TOP,
"&Always On Top");
}
else{

You are using Windows specific features which are off-topic in this
newsgroup. Either switch to standard constructs (std::ifstream,
std::string and std::getline) or ask elsewhere
(http://www.parashift.com/c++-faq-lit....html#faq-5.9).

Looks like the function ReadFile() returns an integer and that you are
comparing it with "ontop=1", which is a pointer (const char*). Check
the documentation on this function.
