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.

    uploading and displaying photos

    I am sorry to be a bit dense about this, but I cannot quite connect all of the dots.
    I can upload a file, change its name, but cannot quite get it into the dbf correctly. I am using the following:
    <html>
    <%a5
    dim session.suspectID as c
    dim msg as c = ""
    if eval_valid("cmd")
    dim t as p
    dim vc_filename as c
    vc_filename = session.suspectID+"_"
    vc_filename = vc_filename+time("0h0m0s3")+right(FileToUpload.filename,4)
    file.from_blob(ServerSetting.Document_Root + "\\" + "image_map" + "\\"+ "images" +"\\" + vc_filename, FileToUpload.data)
    t = table.open("suspect_photos")
    t.enter_begin()
    t.Suspectid = session.suspectID
    t.Photo_Name = image_filename_encode(vc_filename)
    t.enter_end()
    t.close()
    'FileToUpload.filename
    msg = "<a href=\"/" + FileToUpload.filename + "\" target=\"_blank\">" + FileToUpload.filename + "</a> was uploaded as "+vc_filename+"<br /><br />"
    end if
    %>
    <head>
    <title>File Upload example</title>
    </head>
    <body bgcolor="#ffffff">
    <%a5 ? msg %>
    <form action=" <%a5 ? request.script_name %> " method="post" enctype="multipart/form-data">
    <input type="file" name="FileToUpload" ><br >
    <input type="submit" name="cmd" value="Upload File">
    </form>
    <%a5
    ?"Suspect ID is:"+session.suspectID
    %>
    </body>
    </html>
    The photo_name field is an image reference file. When I upload the photo, a record is created, but in the control panel there appears to be nothing in the photo_name field. When I create a grid based on the table, the image does not appear in the grid, just an x in the upper left corner. However, the properties is pointing to the session folder. But I don't believe it should be pointing there, it should be pointing to the images subfolder.

    What am I not understanding?
    Thanks.

    Try:

    Code:
    t.Photo_Name = vc_filename
    All you need is the name of the file, then you use that for your grid's link.

      Steve,
      Thanks for the quick response.
      I tried your suggestion without any luck, but was able to accomplish the issue by using this line:
      t.Photo_Name = image_filename_encode(ServerSetting.Document_Root + "\\" + "image_map" + "\\"+ "images" +"\\" + vc_filename)
      Thanks again.

        Re: uploading and displaying photos

        And for the next part of the program, I would like to put the coding in a grid component to upload a particular individual's picture and automatically associate the picture with the individual.
        I can do that on a form with the following code:
        HTML Code:
        <html>
        <%a5
        dim session.suspectID as c
        dim msg as c = ""
        if eval_valid("cmd")
        dim t as p
        dim vc_filename as c
        vc_filename = session.suspectID+"_"
        vc_filename = vc_filename+time("0h0m0s3")+right(FileToUpload.filename,4)
        file.from_blob(ServerSetting.Document_Root + "\\" + "image_map" + "\\"+ "images" +"\\" + vc_filename, FileToUpload.data)
        t = table.open("suspect_photos")
        t.enter_begin()
        t.Suspectid = session.suspectID
        t.Photo_Name = image_filename_encode(ServerSetting.Document_Root + "\\" + "image_map" + "\\"+ "images" +"\\" + vc_filename)
        t.enter_end()
        t.close()
        'FileToUpload.filename
        msg = "<a href=\"/" + FileToUpload.filename + "\" target=\"_blank\">" + FileToUpload.filename + "</a> was uploaded as "+vc_filename+"<br /><br />"
        end if
        %>

        ?"Suspect ID is:"+session.suspectID
        %>
        </body>
        </html>
        I have tried various combinations in the grid component without any luck. The grid turns to garbage when I try.
        What am I missing?
        Thanks.

            Re: uploading and displaying photos

            No, so I am doing it on an .a5w page that opens in a javascript window when I click a button.
            The page has the following code:
            <html>
            <%a5
            dim session.suspectID as c

              Re: uploading and displaying photos

              I just pasted your code into the editor and run it. I got this error..
              Code:
              C:\A5Webroot\image_map\images\_095201774.png"
              Now I expected an error as I had not done anything to the code but there is something you need to understand if you are using image reference fields in the table.

              Like the table, the image does not reside in the webroot, it resides on the server in your development folder, so if you database was called catchthem.adb and was in a folder called thelaw you would have a sub folder in thelaw called images
              Code:
              c:\thelaw\images
              under images you would have a folder called suspects
              Code:
              c:\thelaw\images\suspects
              you need to upload to that folder, not the webroot, images contained in irf's in tables do not get published, they get delivered to the grid just like data.

              This is a recent and possibly undocumented feature of V10 but I have been very close to its development during beta testing. it really works well.
              One more thing, fact is you cannot show an image in a grid immediately you upload it from a table, you need to trick he grid by having two tables, one with the data and one with the image and a relationship field, the grid needs to be based on a view, not a table, join the two tables, select the fields you want in the grid from your master table and the image from the image table.

              When you upload the image and save, alpha will display the image as the image table has changed in the view settings and forced a refresh.

              Good luck with your projects.

                  Pete or Jay,

                  So with what you are saying about putting pictures in their own folder on the server would the code look like this?


                  Code:
                  file.from_blob(thelaw\images\suspects + "\\" + "image_map" + "\\"+ "images" +"\\" + vc_filename1, FileToUpload1.data)

                    Re: uploading and displaying photos

                    YES, as long as thelaw folder is in the same folder as the database folder e.g. where the .adb file resides. NOT IN THE WEB ROOT. Another way to say it the folder images\thelaw\.. must reside in the same foders the table is in.

                      Jay, is "session.suspectID" the way you are connecting the file to the record?
                      (i.e.) session.suspectID would be the unique ID field from your grid that is passed to the .a5w page that you open in a java window via a button?
