Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

  • Error in file.copy from a table source

    I get this error.... The system can not find specied file

    img_count= TABLECOUNT("t_scoring.DBF", ".T.")
    tbl = table.open("t_scoring",FILE_RW_EXCLUSIVE)
    tbl.batch_begin()
    FOR i = 1 TO img_count
    filename1 = "C:\ACCDB\Pict_upload\Originalfile"
    newfilename1 = "C:\ACCDB\Pict_Comp\Specidnewname"
    file.copy(filename1,newfilename1)
    ' I get the error here
    NEXT i
    tbl.batch_end()
    end

    Scope: to copy files listed in the t_scoring table from Pict_upload to Pict_Comp
    Originalfile is a field in the t_scoring with the names of the original files in C:\ACCDB\Pict_upload
    Specidnewname is a field in the t_scoring with the name of the new file to be in C:\ACCDB\Pict_Comp

    Why the error?

    Re: Error in file.copy from a table source

    How are you fetching the record in t_scoring to get the field value? Your script doesn't appear to be doing that.

      Re: Error in file.copy from a table source

      You are correct I am missing the extraction from the table the Originalfile and Specidnewname field values.
      I just recreate it: But I still get the error "can not find specified file"

      dim tbl as P

      tbl = table.open("t_scoring.dbf")
      tbl.fetch_first()
      while .NOT. tbl.fetch_eof()
      OldName=tbl.Originalfile
      NewName=tbl.Specidnewname
      Oldfilename1 = "C:\ACCDB\Pict_upload\OldName"
      newfilename1 = "C:\ACCDB\Pict_Comp\NewName"

      file.copy(Oldfilename1,newfilename1 )

      tbl.fetch_next()
      end while
      tbl.close()

        Since it is unlikely that all of your filenames exactly fill the fields they occupy I suggest you trim both in the assignments.

        OldName=rtrim(tbl.Originalfile)
        NewName=rtrim(tbl.Specidnewname)

        Also these are not doing what you intend.

        Oldfilename1 = "C:\ACCDB\Pict_upload\OldName"
        newfilename1 = "C:\ACCDB\Pict_Comp\NewName"

        Should be

        Oldfilename1 = "C:\ACCDB\Pict_upload\\"+OldName
        newfilename1 = "C:\ACCDB\Pict_Comp\\+NewName
        There can be only one.

          Thanks to all. It works very well.
          Stan I did not have to use the RTRIM() , but I will add it, just in case.

            Do you understand the difference between

            Oldfilename1 = "C:\ACCDB\Pict_upload\OldName"
            and
            Oldfilename1 = "C:\ACCDB\Pict_upload\\"+OldName
            There can be only one.

              Re: Error in file.copy from a table source

              Not a 100%, maybe 50%?. I belive that by adding the \ is making alpha use the rest as a file name.
              The use of the + is a common practice in alpha to conacatenate.

              How far am I?

              I took that code from the sample file.copy in the documentation. There it did not have the \ or th +

                Oldfilename1 = "C:\ACCDB\Pict_upload\OldName"

                Alpha reads/understands this as
                set the value of Oldfilename1 to "C:\ACCDB\Pict_upload\OldName"
                literally that text inside the outer quotes.

                Oldfilename1 = "C:\ACCDB\Pict_upload\\"+OldName

                Alpha reads/understands this as
                set the value of Oldfilename1 to "C:\ACCDB\Pict_upload\" and concatenate the value in OldName to the end of that.

                The error message you were getting about the file not being found occurred because

                "C:\ACCDB\Pict_upload\OldName"

                was not found.

                  Great, that makes sense.
