    Resolved [RESOLVED] Running Java from VBA to use REGEX on a MAC

    I have some VBA code that works fine on a PC but will not work on a MAC. This is because it makes extensive use of Regular Expressions. The code goes online, pulls track and field results, and parses the text file to populate a database. On the PC, I wrote a vb.net console application that takes in the Pattern and String as arguments and returns the result as a long string to the standard output. I then call the .exe according to a method I found here:

    http://www.vbforums.com/showthread.p...Capture-Output

    Here is my code:
    Code:
        
    Function MyRegex(ByVal MyPattern as String, ByVal MyString as String) as String
            Dim cls As New clsRunApp
            Dim s as String     
            cls.Command = ActiveWorkbook.path & "\bin\RegexHood.exe "
            cls.AddParamater MyPattern & "$" & MyString
            s = cls.RunAppWait_CaptureOutput
            Set cls = Nothing
        End Function
    This works fine.

    My hope is that a simple fix is to re-write the code in JAVA instead. This way, my VBA can run on both platforms. I tested the JAVA code and it works fine. The command that I need to send is, for example:

    java RegexHood \d*$VBforums Rocks1234
    it returns 1234

    I tried to call it using the following modified code:
    Code:
        
    Function MyRegex(ByVal MyPattern as String, ByVal MyString as String) as String
            Dim cls As New clsRunApp
            Dim s as String     
            cls.Command = "java.exe " ' JAVA is in my PATH
            cls.AddParamater ActiveWorkbook.path & "\RegexHood " & MyPattern & "$" & MyString
            s = cls.RunAppWait_CaptureOutput
            Set cls = Nothing
        End Function
    Unfortunately, the code returns a "Cannot find file" error. I tried a few combinations like:

    cls.Command = ActiveWorkbook.path & "\java.exe RegexHood " & MyPattern & "$" & MyString
    (and do not add any parameters)

    Thanks in advance for any assistance.

    Thumbs up Re: Running Java from VBA to use REGEX on a MAC

    Update.

    According to this thread:

    http://stackoverflow.com/questions/8...rom-vba-on-mac

    Even if I could run Java from VBA on a PC, I would not be able to duplicate the action on the MAC as easily.

    Looks like I may have to convert my VBA code to JAVA...which may not be a bad idea in the long run. A quick Google search seems to indicate that there are ways for Java to read and write excel files.

    Thanks to all that chimed in to help.
