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.

    Can we compare two signatures using Topaz signature pad ?

    Recently I bought a topaz signature pad. I am developing a prototype using asp.net application. The device manufacturer provided a document using which i have saved the signature in .sig file format in my local machine. My questions are:
    1. Is it possible to compare two signatures using the topaz signature pad?

    2. How can I compare the current signature with the existing one[no methods provided in the activex control to compare two signatures]

    3. Should I store the .sig file in local machine and then send it to the server? or can I directly save the .sig file in the server?

    4. How many signatures can be stored in a .sig file simultaneously?

    Kindly give some hints to me, those who worked with TOPAZ signature pad or having idea on that.

      You determine the filename and then save it as a <filename>.sig.

      I capture signatures for both clients and employees, but save them as .jpg files. I save the files directly to a folder on our server. If the file already exists, I rename the <old> file as <filemname>.jpg.o and then save the new filename as the .jpg.

      I don't use the .sig files because I cannot use them when printing client and employee ID cards. I need to use .bmp or .jpg format files on the report that is the ID card.

      .sig files are the only legally binding files for signatures as once they are created, you, the user cannot modify them with photoshop or paint or any other editing program.

      Our files are in hidden folders on the server so that users cannot get to them.

      TOPAZ helped a lot when we developed the signature application.

      Finian Lennon created a really nice user interface for capturing signatures that I modified a bit and am using today.

        1) I came to know that, Topaz providing a separate license[sigvalid] for signature comparision, which is the one used by the forensic department too.

        2) Instead of storing signature as .sig file, we can store as "string" itself, so that we can directly store the signature into the database.

        3) A .sig file can contain only one signature.
