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.

  • HTML5 Camera actionscript

    I realize it may be a feature that hasn't been made available yet but just in case I thought I'd check in with you all about it. I am trying to test out the camera feature but am having trouble creating a blob type control which of course then forces me to upload an image to a folder instead of being able to store the image directly inside of my table. When I create a control there isnít a Blob type and I am not sure if that's the problem. I have the image control bound to my image field in the table and it is an "Image" field type. Back end is MS SQL 2008. Anyone else tested this feature our who might know what I am missing?

    Store the image in a varbinary(max) field in MS SQL.

    We've been experimenting with this since the day after it came out, I'm building a major integration of this to OERCA right now. It's easy to build, fast and simple to use.

      Re: HTML5 Camera actionscript

      My field type is varbinary(max) as suggested. When I try to commit the record to the database alpha tells me that the "implicit conversion from data type nvarchar to varbinary(max) is not allowed.

      Is there something I need to do with the control to make it work?

        When I create the control it is a character based control. I don't see an option for blob.

          Josh - I don't understand what you don't understand, and I'm not sure why you're so focused on a blob.

          If you're using MS SQL, use the field type I've already recommended. In the UX component, your control is an Image control. It is that simple.

            That is exactly how I have it configured. Image (Data bound) control. I am using a button to upload the image, when I try to submit the data I receive the error I displayed above.

            As I mentioned above the error I receive is below.
            "implicit conversion from data type nvarchar to varbinary(max) is not allowed"

            It makes a suggestion to use a convert function in my SQL statement but I don't have direct access to the SQL when using the data binding in a ux component.

                Re: HTML5 Camera actionscript

                It looks like it has something to do with the fact that I am trying to use this feature in a repeating section. It's a warranty request form and the user may have multiple items to submit as a single request and I wanted to be able to allow them to attach an image for each item. Looks like thats the problem.

                  Re: HTML5 Camera actionscript

                  I think the data gets passed in as string data in a repeating section. Maybe this is not a supported feature

                    Looks like this was added to the current release

                    UX Component - Image Upload - Camera - Repeating Sections - Support has been added for image upload from a camera into image fields in a Repeating Section.

                      Yes, Selwyn fixed the issue and I've tested it since and all is well.
