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.

  • Capturing external events

    I want Alpha 5 to be notified if say a data file, external to has been added to a folder (latest remote data), accepting that that file can notify windows ! or alpha diectly. Is there any feature that I can run from Alpha that, even if every few mins would check if that external event had occured. Perhaps Active X or some other way ? Like an Intercept or vector detect ?

    RE: Capturing external events

    Walter,

    Build 1389_1027 added

    file.watch_create(c wachname, c path, c flags, c code)


    Will do what you want. Of course, you could also have done it using a timer event on a formor xdialog box to check on a regular basis as well.

    Regards,

    Ira

        Walter,

        The code argument needs to be a character string, So what you need to use is file.watch_create(watch,"c:\",F,"ui_beep()")

          Also I've assumed that "watch" is a character variable. If you are simply trying to use "watch as the name, your code would then be:

          file.watch_create("watch","c:\",F,"ui_beep()")

            RE: Capturing external events

            I have tried the following code below but when run it ties the machine up so much that I have to stop A5 and start again.
            I have tried to use destroy but its already running by that time. Does it run as a thread or do I have to do more? somehow with a timer and how ?

            Is there any further documentation + sample code, since its not in the Existing documentation.

            Eg Used
            Dim monk as C
            file.watch_create(monk,"C:\Test","F","ui_beep()")
