IF-ELSE problems. Why?

[Queatrix]

I have this code:

hFile=CreateFile("Settings.ini", GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
ReadFile(hFile, Buffer, 3, &dwBytes, NULL);
if(Buffer=="foo"){
Beep(2000,2000); }
else {
Beep(500,500); }

But even when my ini file contains the text "foo" the program still returns my if-else statment as false. Why is it doing this? The method works fine in DOS programming.

Was it a dumb question?

You can compare strings like that.... try lstrcmp

You should also be checking the return values from CreateFile and ReadFile to ensure they are working as expected.

[Queatrix]

I dont get it. What do you mean by "try lstrcmp"? In what way?

[Ken Fitlike]

It's a winapi variant of strcmp - see lstrcmp.

[Queatrix]

It doesn't seem to be working, could you give me an example?

[Ken Fitlike]

Traditionally, one posts troublesome code and requests advice on that.

TCHAR buffer[]=_T("hello");
if (lstrcmp(buffer,_T("hello"))==0)
  {
  /*match found*/
  }
else
  {
  /*strings not the same*/
  }

Note the lstrcmp is case sensitive; if you want case insensitivity then use lstrcmpi.

I tried that but it doesn't matter what the text is it always returns as true.

Oops... Sorry, I declared Buffer twice, over writeing what ReadFile picked up.

Thanks for showing me how to do it Ken.
