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.

    Re: Capture Signature on iPad?

    Thanks for this example, it so simple to use compared to other examples I have seen. I have added to it my code, but I need assistance to save the image to a file. I have experience with C# and SQL, and very little with html.

    Thanks

      The code is based upon existing data in the sql backend including binary data.

      Not everyone will or will want to store the binary data in a table.

      So say that you have acquired the signature and want to create a file you will simply decode the signature contents and the create a file from blob.


      Code:
       	dim cn as sql::Connection
       	dim args as sql::arguments
      	dim cs as c = e.tmpl.cs.connectionstring
      	dim v_signature as A
                    dim v_filename as c
      
      ' Open connection and insert data
      	cn.open(cs)
      
      ' Fetch Signature
      	table = "yourtablename"
      	result_expression = "signature"
      
      ' Here you have to define your record identifier
      
      	filter = "id = "e._currentRowDataNew.yourkey
      
      	v_signature = sql_lookup(cn,table,filter,result_expression)
      
      ' decode signature
      	dim bb as b
      	bb = base64decode(v_signature)
      
      ' save to file
                    file.from_blob(v_filename,bb)
      
      Once the file is saved and you know the name, you may reference it in any html code by either static name or reading a table column.

        Hi Omar, Thanks for sending me the VB Scrip code. Do you have the code for c# as I am unable to interpret it.

          The code is Alpha Software's Xbasic IDE that will run at the Web Application Server (WAS) that delivers the html,javacsript,css, etc to the web browser for users to view, process etc. The code presented assumes a sql backend where the signature data is stored in a column and subsequently saves a file at the "WAS" for inclusion into a web-page, grid, etc.
