I wish to check whether a file exist in a folder on my computer. I have below, which can see if a specific file exists:
Function FileExists(sFile As String)
sPath = "M:\User\" & sFile & ".xlsm"
FileExists = Dir(sPath) <> ""
End Function
However, my files are named like: Filename - Version xx.xlsm and is updated regularly. Please note that there will only be one file in the folder, but the filename can vary.
How can I search in the folder using wildcard:
Filename - Version % % and then, if it find any file, open the file afterwards?
One option would be to Open the file inside of the FileExists function. However, I would not recommend doing this. The function should do exactly what the name implies and nothing more.
Another option is restructure your code a little bit:
Private Sub OpenFile()
Dim FileName As String
FileName = GetFile("Filename - Version*")
If FileName <> "" Then
'open FileName as needed
End If
End Sub
Private Function GetFile(sFile As String) As String
sPath = "M:\User\" & sFile & ".xlsm"
GetFile = Dir(sPath)
End Function

I am trying to open a file which will be updated periodically. The current name is "GDE Portfolio Characteristics 12.31.2021" and the idea is to instruct the code to open it, no matter the date (i.e. the last 10 characters). I should only have one file in the folder with such a partial name.
The code I use is the following:
Workbooks.Open Filename:=ThisWorkbook.Path & "\Parametric GDE Portfolio Characteristics*.xlsx"
When running it, it seems it does not find the file. It works if I instead use the entire name of the file.
Newbie problem, but scratching my head in frustration!
Many thanks
There is no way to use a wildcard in the Open-statement. However, you can use the
Dir-command to get the real file name as it allows wildcards:
Dim fileName As String
fileName = Dir(ThisWorkbook.Path & "\Parametric GDE Portfolio Characteristics*.xlsx")
If fileName <> "" Then
Workbooks.Open Filename:=ThisWorkbook.Path & "\" & fileName
End If
Here is a more generic approach:
Sub OpenFiles()
Dim Files As Collection
Set Files = ListFiles(ThisWorkbook.Path, "Parametric GDE Portfolio Characteristics*.xlsx")
Dim Filename As Variant
For Each Filename In Files
Workbooks.Open Filename:=Filename
Next
End Sub
Function ListFiles(FolderName As String, SearchString As String) As Collection
Set ListFiles = New Collection
Dim Filename As String
Filename = Dir(FolderName & "\" & SearchString)
If Len(Filename) = 0 Then Exit Function
Do While Filename <> ""
ListFiles.Add Filename
Filename = Dir()
Loop
End Function
Since I am very new to the excel macro I am trying to develop a code which is able to open the PDF file.But There are some PDF files in my system which are generated by another system therefore those files names change day by day and some figures are included too.
As an example,"Process Report 151120183569844" like this.These figures change everyday.I tried it with adding WILDCARD option but it doesn't work.How do I open this PDF with only a part of the file name?
Sub Open_PDF()
Dim pdfPath As String
pdfPath ="D:\Reports\Process Report*" & ".pdf" 'I used wildcard instead "Process Report 151120183569844"'
Call OpenAnyFile(pdfPath)
End Sub
Function openAnyFile(strPath As String)
Set objShell = CreateObject("Shell.Application")
objShell.Open(strPath)
End Function
As pointed out in another answer, the Dir function with a wildcard should do the trick.
Here's an example using the original openAnyFile function.
Sub Open_PDF()
Dim filePath As String, fileName As String
filePath = "D:\Reports\"
fileName = Dir(filePath & "Process Report*.pdf")
If fileName <> "" Then
openAnyFile filePath & fileName
End If
End Sub
Function openAnyFile(strPath As String)
Dim objShell As Object
Set objShell = CreateObject("Shell.Application")
objShell.Open (strPath)
End Function
You cannot open a file using a wildcard - it's just common sense, what if more than one file was matching your criteria - which one would you want to program to open? You have to specify the exact file name to open it.
if there is just one file in the target directory, you can use something like the following code to open it, regardless of its name:
sFound = Dir(ActiveWorkbook.Path & "\Process Report*.xlsm")
If sFound <> "" Then
Workbooks.Open filename:= ActiveWorkbook.Path & "\" & sFound
End If
I randomly create a new folder on my desktop, in this folder I have one template file with .xlsm extension, which contains my VBA code. Meanwhile I have several csv files saved in the same folder with my raw data.
The purpose is looping through all those csv files one by one, open it, and copy some data and paste to my template file(I know how to do this part) from it and close it after all operations are done.
Currently I meet a problem about how to loop through my folder and open those csv one by one. I didn't set a specific folder name, since I want to share it with other people to use,therefore I use Application.ActiveWorkbook.Path to get the path for my current folder.
Here is my code:
Option Explicit
Sub Range_End_Method()
Dim Dir As String
Dim i As String
Application.ScreenUpdating = False
Dir = Application.ActiveWorkbook.Path & "\"
For Each i In Dir.Files
Debug.Print i.Name
If (i.Name Like "*.csv") Then
Workbooks.Open (i.Path)
End If
Next
End Sub
I'm guessing you want to use the Dir function. To use that, make a call to it, specifying folder and file type in the first call, then call it empty until it returns an empty string. Like this:
Folder = Dir(Application.ActiveWorkbook.Path & "\*.csv")
Do While Folder <> ""
Debug.Print Folder
Workbooks.Open Folder
Folder = Dir()
Loop
You can use this function and macro.
Juste replace MsgBox (myFile + "OK") by the action you want to execute.
FUNCTION
Function ClasseurOuvert(NomFich)
On Error Resume Next
Workbooks(NomFich).Activate
If Err <> 0 Then Workbooks.Open FileName:=NomFich
On Error GoTo 0
End Function
MACRO
Sub LoopFiles()
Dim myPath As String, myFile As String
myPath = Application.ActiveWorkbook.Path & "\"
myFile = Dir(myPath & "\*.*")
Do While myFile <> "" And myFile Like "*.csv"
Call ClasseurOuvert(myPath & "\" & myFile)
With Workbooks(myFile)
MsgBox (myFile + "OK")
End With
Workbooks(myFile).Save
Workbooks(myFile).Close
myFile = Dir()
Loop
End Sub
I am trying to find the command and correct coding to open a PDF file with a relative file path to the active excel file. The code below works fine as a link directly to the file. However, I just need this code snippet to find the PDF file that is sitting in the same file as the opened excel file and open accordingly.
Sub OpeningPDF()
'ThisWorkbook.FollowHyperlink "C:\Users\Michael\My Documents\totals\copy.pdf"
End Sub
I tried working with ThisWorkbook.path but nothing I tried with that worked or seemed to be outdate. Any help in this matter would be much appreciated.
I have found two solutions to this:
The first one is using the built-in Shell() function. This should automatically resolve the relative path (relative to the applications current working directory):
Public Sub StartExeWithArgument()
Dim strFilename As String
strFilename = "../folder/file.pdf"
Call Shell(strFilename, vbNormalFocus)
End Sub
The second one uses the Shell.Application COM Object and will basically do the same as the first one.
Sub runit()
Dim Shex As Object
Set Shex = CreateObject("Shell.Application")
tgtfile = "../folder/file.pdf"
Shex.Open (tgtfile)
End Sub
If you start with ThisWorkbook.Path and your relative-reference, then trim a layer off for every "..\" in the relative reference, you'll get the path.
Function RelativeToAbsolutePath(ByVal RelativePath As String) AS String
Dim TempStart AS String, TempEnd AS String
TempStart = ThisWorkbook.Path
TempEnd = RelativePath
If Left(TempEnd,1) = "\" Then TempEnd = Mid(TempEnd,1)
RelativeToAbsolutePath = ""
On Error GoTo FuncErr
While Left(TempEnd,3)="..\" AND InStrRev(TempStart,"\")>0
TempStart = Left(TempStart,InStrRev(TempStart,"\")-1) 'Remove 1 layer from Workbook path
TempEnd = Mid(TempEnd,4) 'Remove 1 instance of "..\"
Wend
RelativeToAbsolutePath = TempStart & "\" & TempEnd 'Stitch it all together
FuncErr: 'You may want a DIR(..) check to see if the file actually exists?
End Function
You can then open it with Shell
I am trying to iterate through files using Dir, and I understand that it works differently on Mac than windows. This question has been helpful, but I have been unable to implement the solution suggested. The first call to Dir successfully returns a desired filename, but the second call crashes excel. I would like to implement a pattern like this:
Sub printFileNames()
Dim path as String
Dim fileName as String
path = ThisWorkbook.Path & "/SUBFOLDER/"
fileName = Dir(path, MacID("XLSX"))
While fileName <> ""
MsgBox fileName
fileName = Dir 'This CRASHES EXCEL
Wend
End Sub
Here is a screenshot of the error message, upon crash:
Is this a known bug? Am I using Dir incorrectly for the Mac version of Excel 2016?
EDIT:
I have also tried using this exact solution, posted in the above linked question:
Sub Sample()
MyDir = ActiveWorkbook.Path
strPath = MyDir & ":SUBFOLDER:"
strFile = Dir(strPath, MacID("TEXT"))
'Loop through each file in the folder
Do While Len(strFile) > 0
If Right(strFile, 3) = "csv" Then
Debug.Print strFile
End If
strFile = Dir
Loop
End Sub
But this gives a "File Not Found" error, even though there are both .csv, .txt, and .xlsx files in the specified folder. Using:/SUBFOLDER/ instead of :SUBFOLDER: prints the appropriate file name for the first loop, but crashes upon calling strFile = Dir
