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.

  • How Do You Append Date To File Upload?

    Using action javascript File Upload in a UX, how can you automatically append the current date/time stamp to the filename before uploading?

    So I think this can be done with the file transformation. But I'm having trouble with the stritran function to remove the ""'s in the date. Anyone know the syntax that will work here for the transformation?

    If I can't make it work in here, I will resort to populating a textbox with the current date, manipulate the formatting, then add the {date} placeholder in the transformation. Should work.

        What I meant is how to remove the 'forward slashes'?

            Thanks Pete, that is very helpful. I was trying to use stritran to format it and getting nowhere. This works great using the dtoc formats.

              "Filename"+"_"+remspecial(dtoc(date()) or my favorite "Filename" +"_"+time("yyyyMMdd",date()) should work too.

                    So I have come to find that this File Transformation Expression does NOT change the name of the file being uploaded.
                    What is does is change the path that gets saved for the file location in your database.

                    For example if your file is called Spreadsheet.xls and you are uploading to C:\Temp
                    When you do the file upload using the file transformation appending the date, the file is uploaded to C:\Temp as Spreadsheet.xls and the database field that is data bound to the control to store filename gets saved as C:\Temp\Spreadsheet.xls_2021-06-11


                    If I use the built in Alpha property File Exists - Rename it will append Spreadsheet_1.xls, Spreadsheet_2.xls, etc. to the actual file name.

                    Is anyone actually using a method of uploading a file and automatically changing the name of the file itself without user intervention?

                      and this is worth a look.
                      https://documentation.alphasoftware....e%20Upload.xml

                      What's sad about this is developers need to journey back to the past to try an develop for the future, Oct 05, 2014 to be exact.

                      Unfortunately developers get a lesson in data-bound dialog controls to get some kind of solution, and I think it is fair to say - its a relic method these days. Almost 7 years have passed since the current video which wants to handball the developer to xbasic to complete this, what appears a simple thing to do. Considering now more than ever the web and applications are visually driven, it may be time for the client-side no-code-low-code JS interface be developed for AA and remove the past to avoid confusion. AA is a great product but the legacy methods and controls still promoted while the List and Viewbox now do most things is an issue.

                        Some developers have managed to do this using the AfterUpload javascript property to call an xbasic function which then uses file.rename to rename the physical file.
                        I am trying to work through this, but so far have not been successful.

                          Turns out there is a very simple way to rename a file with the File Upload action javascript action. Sarah pointed out that there is an 'e' object available in the On Stored Filename Compute Xbasic Function called e.targetFileName.

                          I've attached a quick and easy method along with some sample Xbasic code if anyone is interested.

                          Thanks Sarah
