问题 I have an XML file that has file attachments encoded in Base64 within it (InfoPath). When I use Powershell to decode the Base64 string for the attachment, it seems like I have to write the file path and extension into the WriteAllBytes command but I don't know whether the original file was a PDF, image file, DOCX, etc. - is there a way to have it write the string into the original filename and/or extension and I just specify the folder where it needs to go? Example code: $b64str = $xml

问题 I am running PowerShell 2.0. I have a PowerShell script that adds a record to the database and returns the ID of the record added. The record ID is returned as a property called new_deal_id within a DataRow object (called ResultSet ). If there is a problem on the database end it is possible that the new_deal_id property does not get set, or doesn't exist at all. To counter this scenario I wrapped the reading of the property in a try/catch block as shown here. try { $ErrorActionPreference =

问题 I have created this simple script below to loop through a file containing a list of users and apply quota rules for each user in the file. It works, but during processing it fails sometimes as I believe the large number of users in the text file blocks access at times.
