Visual BasicYou just got that shiny new digital camera, and then you downloaded a bunch of digital pictures to your computer.

The following instructions will show you how.

Creating an HTML File List with VB - Opening the Dir.txt File and Creating the HTML File
(Page 4 of 5 )

To create the catalog HTML file:

  1. Create the HTML headings
  2. The dir file will have to be opened for input
  3. Read in a line
  4. Output the line in HTML format
  5. Skip to the next record
  6. Do 3-4 until finished
  7. Create the end of the HTML file
  8. Close the files

From the above pseudo code, you can tell there will be a file input, a file output, and a loop.

The subroutine will look like this


Private Sub cmdCatalog_Click()
On Error 
GoTo Err_cmdCatalog_Click
  
'run directory listing
  '
put the path in the shell command where you put the dir.bat file
  Dim RetVal
  RetVal 
Shell(txtLocation "dir.bat"1)    ' Run dir.bat
  '
open file for input and output
  
'change path for your system
  Open txtLocation & "dir.txt" For Input As #1
  Open txtLocation & "catalog.htm" For Output As #2
  
  '
create HTML headings
  
Print #2, "<HTML><HEAD><TITLE>MY Pictures</TITLE></HEAD><BODY>"
  Print #2, "<center><h1>My Pictures</h1></center>"
  Print #2, "<OL>"
  'create loop, open file
  Do Until EOF(1)
  
    'get line from file
    Input #1, txtFile
  
    'output line to catalog
    Print #2, "<LI>"
    Print #2, "<a href='" & txtFile & "'>" & txtFile & "</a><br>"
    Print #2, "</LI>"
  Loop
  
  'create HTML end
  Print #2, "</OL>"
  Print #2, "</BODY></HTML>"
  
  'close files
  Close #1
  Close #2
  
Exit_cmdCatalog_Click:
    Exit Sub
Err_cmdCatalog_Click:
    MsgBox Err
.Description
    Resume Exit_cmdCatalog_Click
End Sub
