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.

    action Javascript File Download from database not working

    I have a UX component that uploads a pdf, doc, or xls. That is working fine, but when I have a user try to download the file it comes back corrupted no matter the file type If I download the blob from MySQL and I change the file type from bin to pdf, doc or xls it works. so the file is being uploaded correctly.

    When I go to the action javascript I made to file download I have attached the options I have selected.action javascript.PNG

    The export filename options is a static field has been put in with the text "download", But the client-side <default> which should name the file to what is stored in the database does not populate when I try to download the file. The file name is "download".xls or .pdf or .doc, whatever the correct type is. The help says that the The downloaded file name should remain the same name of the file that is stored in the database.

    But even if I try to rename it or try to open it says it is corrupted and cannot open the pdf or doc.

    If you need more screenshots of what is going on I can get them, thanks.

    Are you downloading a file from the server... or are you trying to download a file which has been stored in a MySQL Blob field?

        I believe the inline help text is correct... but I think there is a bug in a specific section.

        Export filename must be set. Your screenshot shows a blank... although you've mention it's set to "download".

        The help reads that for a linked file, the filename of the file on the server will be used. For an embedded object - which is what we're dealing with - a system generated filename will be used... which will be the Export filename.

        I wanted to set my own filename, so I used the Client-side filename as set a function... function:setFilename... but it doesn't work... I'll report that.

        You should be able to create a Javascript function...

        Code:
        function setFilename(){
        
        	debugger;
        	var fileName = {dialog.Object}.getValue('binaryDesc');
        	return encodeURIComponent(fileName);
        
        }
        Where "binaryDesc" is my File name... only... no extension.

        But, my filename actually comes down as function-setFilename... so something is wrong.

        Overall, the File Download Action is working. My png and pdf files are coming down without error. PDF files are downloaded and automatically opened.

        If you want to post your UX and a sample table I'll have a look.

            when I created the screenshot I didn't have anything in there, but when I saved it and published I put "download" in that field.
            I'll try to use the javascript and post the results.

                    I created a new UX component and the download name is not working again. After spending an hour on trying to figure it out. I don't understand why there is not a dropdown for the field that is the name of the file.

                    I added the code above
                    function setFilename(){

                    debugger;
                    var fileName = {dialog.Object}.getValue('binaryDesc');
                    return encodeURIComponent(fileName);

                    }
                    and it didn't work this time.
