I'm to trying to convert a PDF file to JPEG image using VB6.0

I tried the attached code but when it tries to open the PDF file, I get error Activex Component cant create object.
isOpen = pdDoc.Open("D:\test.PDF")  --------------> errored line

Please advice.
Private Sub Command1_Click()
        Dim pdDoc As New Acrobat.AcroPDDoc    'Acrobat.CAcroPDDoc
        Dim page As Acrobat.AcroPDPage  'CAcroPDPage
        Dim pt As Acrobat.AcroPoint
        Dim rect As Acrobat.AcroRect
        Dim data As Object              'IDataObject
        Dim bmp As System_Drawing_Bitmap                 'Bitmap
        Dim strPathString As String
        Dim isOpen As Boolean
        Dim lngNumPages As Long
      
        
       isOpen = True
       
        ' Begin creating the pdf
        isOpen = pdDoc.Open("D:\test.PDF")
      
              page = Nothing

              doc.Open ("D:\test.PDF")

              page = doc.AcquirePage(0)

                pt = page.GetSize()

                rect = New Acrobat.AcroRect

                rect.Top = 0

                rect.Left = 0

                rect.Right = pt.x

                rect.bottom = pt.y

            Call page.CopyToClipboard(rect, 0, 0, 100)      
            data = Clipboard.GetData()                      
             bmp = data.GetData(DataFormats.bitmap)
             bmp.Save ("D:\test.jpeg")
               
End Sub

I dont have acrobat pro or the ActiveX but there are some issues with your code.

1/ always Turn on  Option Explicit  ... it saves simple mistakes.

try this.
Option Explicit      '<<< first line of module/form

Private Sub Command1_Click()
        Dim pdDoc As Acrobat.AcroPDDoc    'Acrobat.CAcroPDDoc
        Dim page As Acrobat.AcroPDPage  'CAcroPDPage
        Dim pt As Acrobat.AcroPoint
        Dim rect As Acrobat.AcroRect
        Dim data As Object              'IDataObject
        Dim bmp As System_Drawing_Bitmap                 'Bitmap. <<<< NOT VB6. this is .NET but may work?
        Dim strPathString As String
        Dim isOpen As Boolean
        Dim lngNumPages As Long
      
        
       isOpen = True
       
        ' open the PDF
        Set pdDoc = CreateObject("AcroExch.PDDoc")  '<<<<
        
        isOpen = pdDoc.open("D:\test.PDF")
      
            Set page = Nothing
            
            page = acroPD.AcquirePage(0)
            'may need Set page = acroPD.AcquirePage(0)
            
            pt = page.GetSize()
            
            Set rect = New Acrobat.AcroRect
            
            rect.Top = 0
            
            rect.Left = 0
            
            rect.Right = pt.x
            
            rect.bottom = pt.y

            Call page.CopyToClipboard(rect, 0, 0, 100)
            data = Clipboard.GetData()
            bmp = data.GetData(DataFormats.bitmap)
            bmp.Save ("D:\test.jpeg")
               
End Sub

for a fully vb6 method of saving bitmap... http://www.bigresource.com/Tracker/Track-vb-lnXdBCddZl/

you need to use an picturebox control as an intermediate step.

Thanks for your valuable comments.
But the problem I have is when i try to open a PDF document on the line.
isOpen = pdDoc.Open("D:\test.PDF")
I tried Option Explicit , but it didnt help.

I have Adobe Reader9.0 installed on the machine, do i need to have Adobe Professional? Please let me know.

definitely need Acrobat Pro.    The free Acrobat Reader does not include any methods of opening PDF files directly within VB6. And no methods of manipulating PDF.  other than shell to PDFTK, a third party app.
