i have an app that pings all IP's on my network and then adds all alive hosts to a list, then my WMI query runs for all of them ips and gets some information. it all works fine except for when it gets to printers and switches/routers which obviously dont support WMI. Is there some way i can check if a device supports WMI and skip the query if it does not?

Trying to write a Vbscript. Actually, I'm trying to modify an existing script that I found on the internet. I basically need the script to run on workstations, delete printers from our old print server (master), and install the corresponding printer from our new print server (dc01). I should also mention that the printer names have changes slightly. So far, the script does a great job of deleting printers from Master, but none of the corresponding dc01 printers are installed.
Here's the code:

Am looking at making a small application that will list printers on two file servers at two separate sites, from this app they can add the printer/s to there local computer.
I have found a small application on the web but there are a few improvements it could do with.
They are; Show all local printers without having to click on a check box. Show sites printers without having to click on a check box. Show comments about the printer�s location other then just the site.
If it is possible I would like to update this one, but if there are any other examples where I could download something similar, or even some help with how to begin to create a new application.
Here are some screen shots, of the application form and the xml which holds the folder structure for the sites.
I am trying to bind an Access database to a MSChart control in VB Net 2008. I have a test database populated with four fields SAMPLE-DateTime, Values-Number, MAX-Number and MIN-Number. I'd like to only display the rows that fall within a specific date range but I'm running into a problem when i try to execute the following command:
cmd = "SELECT SAMPLE,VALUES,MAX,MIN FROM TABLE1 WHERE [CHECK_DATE] BETWEEN 01/01/2009 AND 01/01/2011"

View 1 RepliesTrying to work out if there's a nice way of doing this, preferably in Linq rather than loops, which is what I've done for now.
I want the number of days my Product is active between two dates.
Product has many ProductHistories, ProductHistory has values for DateActive and DateInactive. DateInactive can be null, and often will be, to show that this history is ongoing. Histories won't overlap.
I want to sum the maximum of my startDate or the ProductHistory's DateActive, and subtract that total from the sum of the minimum of endDate or ProductHistory's DateInactive (endDate by default if DateInactive has no value).
Worked example:
Get active number of active days between 2011-01-01 (1st Jan) and 2011-02-01 (1st Feb)
Histories:
Active 2010-12-25 : Inactive 2011-01-05
Active 2011-01-15 : Inactive 2011-01-20
Active 2011-01-25 : Inactive null

I have three tables,
Products(ProductID, ProductName)
Orders(OrderID, OrderDate)
OrderDetails(ProductID, OrderID) Junction table between Products and Orders.
For example, there are Three ProductID in Products table A01, A02, A03
Four OrderID in Orders table
1. 01/01/2009, 2. 03/01/2009, 3. 05/01/2009, 4. 07/01/2009.
OrderDetails data as below:
A01 -- 01/01/2009
A02 -- 01/01/2009
A01 -- 03/01/2009
[Code]....
then I want to display the date that A03 is not ordered from range 02/01/2009 till 08/01/2009 which could have the result like this.
DateMissingOrder for Product A03 in range of date 02/01/2009 to 08/01/2009:
03/01/2009
07/01/2009

I'm using VS 2008 and .NET 3.5. I'm in one of my programs and when I run the program to test it, I keep getting these errors... 'Exception occurred' And the line is highlighted green and there's a green arrow on the side line (where you can enter breakpoints). When the code stops at these exceptions, I can hit continue and the code still runs just fine even though there were a ton of exceptions. Now, I'm wondering if there is a way that I can skip over these or have them not show up because I know the files that this is happening have not been changed in several weeks and I've tested this program beginning of this week and it was working fine... no exceptions or anything. I'm not sure what would've changed. The only thing I did was install the newest versions of Telerik Rad Controls. That should have nothing to do with the exceptions I'm getting.why i'm getting these now all of a sudden or how I can just skip over these without having to hit continue after each time?

I have multiple forms and reports with different print area. Some are designed to print to a thermal label printer and others to department shared printers. Currently the user is able to change the printer in print dialog box and print to differernt printers. I want to be able to create a form where the user can assign different printers for different jobs and not have to worry about it.
The problem is, i have never worked with printing function and my collegues arent too smart so I was wondering if someone can throw me ideas on where to start so i can start googling for it.

I have what is basically a text only printer (a Zebra 105SL) connected to my network at a static IP address. I have downloaded Zebra's Text only driver for it and set up a print queue named "Zebra North Text". I can print to that queue from Notepad just fine.
However, I am trying to print from a VB 2005 (soon to be upgraded to VB 2010 or VB 11) application. All of the standard VB sample printing code assumes I need to render the text in Fonts, etc, which just confuses the Text Driver.[code]...
