Windows API URLdl2file...

Please excuse if this isnot the right forum to post this...Here is something that works on vb but doesnot seem to be working with C++

PHP Code:

---

bool DownloadFile(char* remote, char*local){
    return (URLDownloadToFile(0, remote,local,0,0)==S_OK);
} 


---

its being used like this:

PHP Code:

---

LPSTR listAddr = "http://kaillera.com/raw_server_list2.php";
LPSTR srvFullRaw = "C:\\srvList.raw";
if(DownloadFile(listAddr,srvFullRaw))
    etc... 


---

which doesnot seem to be working...On the other hand the same thing in vb works quite fine...

Code:

---

Public Declare Function URLDownloadToFile Lib "urlmon" Alias "URLDownloadToFileA" (ByVal pCaller As Long, ByVal szURL As String, ByVal szFileName As String, ByVal dwReserved As Long, ByVal lpfnCB As Long) As Long
Public Function DownloadFile(URL As String, LocalFilename As String) As Boolean
    Dim lngRetVal As Long
    lngRetVal = URLDownloadToFile(0, URL, LocalFilename, 0, 0)
    If lngRetVal = 0 Then DownloadFile = True
End Function
Sub Main()
    DownloadFile "http://kaillera.com/raw_server_list2.php", "C:\srvList.raw"
End Sub

---

Just wondering what was wrong with the C++ code and how I might go around fixing it.

Thanks

(Wonders if the LPSTR type is equal to char*)

What about:

char* listAddr = "http://kaillera.com/raw_server_list2.php";
char* srvFullRaw = "C:\srvList.raw";
if(DownloadFile(listAddr,srvFullRaw))

???

The definition here uses LPCTSTR instead of LPSTR.. If I read this correctly it's a difference in Unicode/ANSI style strings.. You probably need to use the Unicode version..

Another thing I remember (it's been a while) is that NULL!=0..

SirDice, Quick check... He calls URLDownloadToFileA and the A at the end suggests this is the ASCII-version of this functioncall. If he had used URLDownloadToFileW then I would agree with you that he needs WideChar (Unicode) strings here.

However, the C code that's posted here doesn't tell us which version of this procedure is actually loaded here. You could be right that this function in C++ links to the Unicode version while the version in VB is linked to the ASCII version.
