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.

    Change font size in TextArea

    I have a textArea field where the user enters a paragraph of so of text. I need to provide a method to increase or decrease the size of the text in the textArea field. I thought I could do this in the style smart button on the design side, but it seem to ignore any changes I make. I tried playing around with the HTML text editor control but that created an overlay box that is larger than the entry window and cause other issues. Question...can you dynamically change the font size in a text area field?

    From my experience, if you have 'HTML editor' checked, it will ignore the Style button css settings and make a basic text area that the user would use the HTML controls to control the style.

    Do you want the end-user to be able to control the text size?

      Do you want to increase or decrease the size based on the amount of content so that it fills the form? Do you want that automatic or manual?

        Hi

        I'm looking for a plus/minus button to increase or decrease the size of the entire text in the text area box. I can see a method using javascript to grab the text, add html style markup and return it to the field. I then will need to strip the HTML before I save the data. One problem I see with this is, as new text is added I would have to resize it again.

        Question...Can I get a pointer to the text area box and dynamically change the style?

          OK I found it....

          What was confusing me is that fontSize has to be in camel case or it won't work. Now that I have this I can write the rest to increase or decrease the text size.

          Code:
          var ele = {dialog.object}.getPointer('Session_Note');
          if (ele) {
          ele.style.fontSize="40pt";
          ele.style.color = 'red';
          }
