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.

    Re: Embedded OLE PDF

    But the only OLE object I see in Alpha is an OLE BMP. (which doesn't work.)
    Is it possible to view this data in A5 or do I have to extract it into a PDF file.

    Are you trying to show the pdf on a grid? in a page? Are you trying to make the file available for download? Are there security concerns?
    What exactly are you trying to do?

    If youre storing the raw bytes, thats fine. But you need a page to serve those raw bytes to an object tag (if you want to display the actual pdf in the browser)

    You can try using the object tag with an embed fallback and provide a "server" page (in the sense that the page serves content, not in the sense that the page resides on the server) that sets the mime type provides the bytes.

    <object data="getPDFFile.a5w?document_id=<%a5 ?document_id %>" type="application/pdf" width="100%" height="100%">
    <embed></embed> //go lookup the embed tag

    The getPDFFile.a5w would do something like
    'connect to the database
    'verify permissions
    'if permission is granted - output the pdf bytes
    You might have to use
    header('Mime-Type: application/pdf'); (Go do some digging) and then

    Heres an example with an image file:
    dim x_id as N
    	dim conn as SQL::Connection
    	dim sql as C=""
    	dim args as SQL::Arguments
    	dim type as C="thumbnail"
    	if eval_valid("Request.Variables.aid") then
    		if"::name::conn") then
    			sql="SELECT * FROM x WHERE x_id=:aid"
    			if conn.execute(sql,args) then
    				dim filename as C
    				if type=="thumbnail" then"x_thumbnail")
    				end if
    				if file.exists(filename) then
    				end if
    			end if
    		end if
    	end if
    Another page / Freeform HTML field on a dialog / Freeform HTML field on a grid / whatever else you want
    	?"<img height=100 src=\"handlers/serve_image.a5w?aid="+Request.Variables.aid+"\" />"

    That is normally how I would do it too, but it's an import of someone else's data.

    I'll work around it instead, thanks.

    Personally, we dont store blobs in the database.
    We store files in the file system and store the fullpath in the DB.

    THats probably your best bet

    Embedded OLE PDF

    I have a table that was converted from Access to MS SQL. In this table is a field with an embedded PDF.

    How can I display the embedded PDF? In Access it is an OLE Object.

    But the only OLE object I see in Alpha is an OLE BMP. (which doesn't work.)

    Is it possible to view this data in A5 or do I have to extract it into a PDF file.
