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.

    a5_scale_imageblob stores empty file

    I have a drag and drop image upload in my UX component that calls an a5w page that runs xbasic to handle the upload to an S3 server and log the file locations in a SQL database. I am trying to convert the blob to a thumbnail image on the A5 server. First I tried a5_runimagemagiccommand but with absolutely no success. The command runs with no errors but does not perform the transform function. I wanted to use image magic so I can create thumbnails from pdfs but after many many hours, I have decided to abandon image magick and use the a5_scale_imageblob command. I run the command, it saves the file on the server as it should. However, the file is empty and is 0 bytes. Does anyone know why neither one of these commands work?

    A snippet of the relevant code for each command is:

    dim vpath as C
    dim thumbpath as C
    dim filename as C
    dim imageType as C
    dim thumb as B

    vpath = "x:\mypath"
    thumbpath = "c:\A5Webroot\mypath"
    filename = file.filename
    file.from_blob(vpath + filename,file.data)
    imageType = right(file.filename,3)

    'This is the image magic attempt

    a5_runimagemagiccommand(vpath+filename,thumbpath+filename,"-resize x240")

    'This is the internal scaling attempt

    thumb = a5_scale_imageblob(file.data, imageType, imageType, 0, 240, "pixels", "max", "proportional")
    file.from_blob(thumbpath+filename,thumb)

    Can anyone see what is going wrong?
    BTW, I have imagemagick installed on the server and working from the command line.

    Thanks,
    Rob
