VBA FTP file download doesn't work on 64bit machines

Hello,


I'm having some problems regarding the editing and making the code to compile and work successfully on 64-bit Versions


PHP: 
https://www.jkp-ads.com/articles/apideclarations.asp
-> I've followed the differences of the code using the site here were each declaration can be saw on both versions and with a windows api program to display functions declaration correctly but on 64 bit machines the file is detected, but not downloaded. The same code works and downloads the entire test file correctly.</div>



Piece of code (also the entire document has been attached)


Please note
- I've setup a private ftp server with and user and password test with no write access (this will be my case).
- After the problem is solved the user will be deleted.
- The server uses an ftp active connection type.
- It will not work to connect with filezilla.




If someone can suggest a place or a tutorial or something in order to arrange correctly the transition from 32 bit code to 64 i will be forever grateful.


Code: 
Public Const INTERNET_FLAG_RELOAD = &H80000000


Const MAX_PATH = 260
Const INTERNET_SERVICE_FTP = 1


 
Private Type WIN32_FIND_DATA
    dwFileAttributes As Long
    ftCreationTime As Currency          'low & high 32 bits as 64-bit data type
    ftLastAccessTime As Currency
    ftLastWriteTime As Currency
    nFileSizeHigh As Long
    nFileSizeLow As Long
    dwReserved0 As Long
    dwReserved1 As Long
    cFileName As String * MAX_PATH
    cAlternate As String * 14
End Type

Please note that the issue has been posted also here --> https://www.excelforum.com/excel-pr...e-download-doesnt-work-on-64bit-machines.html but without any answers so far.

I'm not an expert on the Windows API, but parameters like dwFlags are just data values, not pointers, therefore don't change them to LongPtr. Also, the Win64 compiler constant is True if you've installed the 64-bit version of Excel, not whether Windows is 64-bit. I don't think any of the Internet/Ftp functions you're using differ between 32- and 64-bit Excel, therefore I think you should use the VBA7 constant instead. Try these declarations, untested though:

Code:

Hello, i've tested your code and a new error is now displayed : type mismatch here --> ret = InternetOpen(

ftpMode = 0 'active mode FTP
'ftpMode = INTERNET_FLAG_PASSIVE 'passive mode FTP

located here after the ftp mode declaration :
ret = InternetOpen("ftp VBA", 1, vbNullString, vbNullString, 0)

I haven't looked at your whole code, only the code posted here. The VBA7 declaration of InternetOpen returns a LongPtr, therefore your declaration of the above 'ret' variable should be:

Code: 
#If VBA7 Then
   Dim ret As LongPtr
[URL=https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=Else]#Else[/URL] 
   Dim ret As Long

You need 2 LongPtr declarations for hOpen and hConn then, also within the #If VBA7 clause. Remember, it's not just the API declarations which need to be changed but also the variables used as arguments and the variables which the return values are assigned to.

ok sorry for the response with delay :

Modified to :

    [URL=https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=If]#If[/URL]  VBA7 Then
        Dim ret As LongPtr
        Dim hFind As LongPtr
        Dim hOpen As LongPtr
        Dim hConn As LongPtr

       Dim ret As Long
       Dim hFind As Long

       Dim hConn As Long
    [URL=https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=End]#End[/URL]  If

Error now at hopen from here (mismach):

Code: 
    ret = InternetOpen("ftp VBA", 1, vbNullString, vbNullString, 0)
    hOpen = ret
    
    If ret > 0 Then
        ret = InternetConnect([I][B][U]hOpen <---here[/U][/B][/I], hostName, port, username, password, INTERNET_SERVICE_FTP, ftpMode, 0)
        hConn = ret
    End If

That last error suggests the #Else part of the #If Win64 in your code in post no. 7 is being executed, which means your Excel isn't 64-bit. Run this to find out:
Code: 
Sub test()
    [URL=https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=If]#If[/URL]  Win64 Then
        MsgBox "Excel is 64-bit"
    [URL=https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=Else]#Else[/URL] 
        MsgBox "Excel is 32-bit"
    [URL=https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=End]#End[/URL]  If
End Sub
As I said previously, I think you should be using #If VBA7 around the API declarations instead of #If Win64, regardless of bit length.
