VS 2010 ManagementObjectSearcher Won't Recognize As A Class

Jun 7, 2011

VS won't recognize this as a class, I get the "Type 'ManagementObjectSearcher' is not defined." error. Usually when this happens I just need to import something, in this case it's System.Management, however this doesn't do anything. I'm quite new to programming so it's probably some very simple mistake or misunderstanding.

VS 2010 Recognize Time And Date In CSV File?

Mar 28, 2011

I'm building an application in which a certain CSV schedule is read and searched for time and date values.

I want to read each cell in the CSV file with a streamreader and have VB determine if the contents of the cell represent a date (like 31-10-2011), a time (like 22:30) or random text data which is not formatted like a date or time.

How can I make VB recognize a string as either a date, a time or neither one, so I can use this string formatted as Date, Time or discard of it?

The contents of the CSV file will look something like this:

;Schedulename;text;text;31-10-2011;text;text;6-11-2011;text;;;text

Although the CSV file will never contain much data, the position of the date and time fields in a row may vary, so I cannot tell VB which cell to read as date/time. It has to recognize the value as date, time, or unusable text.

Dim CSVReadline As New System.IO.StreamReader(schedule.csv")
Cellcheck = CSVReadline.ReadLine()
String = Cellcheck.Split(";")
For i = 0 to 10
Scheduledate = String(i) ............ etc.

VB: Release A Device That Already In Use [ManagementObjectSearcher]?

Jun 12, 2011

I am currently working on an application for use with scanning an printing devices. I use the ManagementObjectSearcher in order to retrieve device names and Id's:For example using (Don't forget to add the reference to System.Management.dll in the framework 2.** folder if you're trying the code)

Dim searcher As New ManagementObjectSearcher("Select * from Win32_PnPEntity")
Dim PnpDevice As ManagementObject
For Each PnpDevice In searcher.Get()

[code]....

There are various classes such as:
-CIM_LogicalDevice
-Win32_PnPEntity

Allow access to various properties-- most of which are read only.

Question: Is it possible through one of these classes to reset a scanning device that is already in use or check on its current status.

-CIM_LogicalDevice("Status")--Win32_PnPEntity("Status") return the value of "OK" when the scanner is in use by another application. So that property must not be what I'm looking for.

I just want to query the device and if it is in use (from a failed attempt or human error) reset the device. The object that calls the scanner/printer is waiting for an event handler(successful scan) that sometimes does not occur and I cannot dispose of the object locking the device up as "in use."

How do I free the device? Or would the solution be to create a timer which waits for the event handler which could contain a property flag set to true if it occurs. If the event doesn't occur in a given timeframe and the flag is false dispose the object?

Generic Failure With System.Management.ManagementObjectSearcher?

Apr 3, 2011

I have some software that does the following code to try to loop through the software (MSI's) that are installed on a machine. Originally it was passing in a package name as a parameter, but I've simplified my code to make it easier to follow. It was working before, I can't figure out why it's not now. Here's an example snippet with a package that doesn't exist:

This method works great for InstanceID, Version and SKUName but now I'm trying to find the installation root as well. For SQL 2005 it appears the property name was SqlDataRoot, but has since been depreciated.
