 If the same file name already exists in the target folder, it will automatically be over-written. The best way to address this situation if it might occur is to use a variable (such as a timestamp created with a VBScript step) to make the file name unique for each processing cycle. If the same file name already exists in the target folder, it will automatically be over-written.

-Signature data is stored in a column in the table used by the Versago Form. It is stored in a format that must be converted back to BASE64 before it can be used. This is done with a SQL Stored Procedure. The procedure does the conversion and stores the converted data in a new table. Following is a framework version of the procedure.+Signature data is stored in a column in the table used by the Versago Form. It is stored in a format that must be converted back to base64 before it can be used. There are two ways to approach this. 
 + 
 +====Option 1==== 
 +When you know that a form will be capturing a signature, the conversion can be done in the **CustomPostExecute** procedure.  The framework code shown below can be included in the CustomPostExecute procedure, the framework procedure can be called from the CustomPostExecute procedure. The framework procedure does the conversion and stores the converted data in a new table. This can then be used by Bizweaver to create an image file for use in reports, etc. The advantage of this approach is that the signature images can be created automatically and stored on disk for future use. Following is a framework version of the procedure.

 +====Option 2====
 +The signature image can also be converted as needed in a Bizweaver workflow.  In this case a SQLCommand step is used to parse out the signature data using <code sql>substring(Signature,23,999999)</code> on the database column that holds the signature data.  This step feeds into a FileWriter step using the Binary Output option to convert the base64 data back to an image file, which is saved to disk for subsequent use.
