View 2 RepliesI'm learning about the cultureinfo and doing ok but there is one thing I can't work out.I'd like to know how to find out the display settings of the date for the user pc.For example, I have an American bought laptop using the us culture so the date will be MM/dd/YY but I have changed the date setting to read dd/MM7YY. So that means I haven't actually changed the inbuilt cultureinfo, I've just "altered" a setting and it's that setting I want to access. When my project starts I have a label that I want to read as dd/MM/YY.With another pc it might be different - the culture might be uk but the date setting might be changed MM/dd/YY so I want the label to read MM/dd/YY etc etc etc.If the cultureinfo hasn't been changed then I want the label to read whatever the date is set to etc.

I'm frustrated beyond belief that I can't find the proper API calls to get the information. If anyone knows how to do this, PLEASE share it here!! I know it is possible, because other shells do it. -Ray"

View 7 RepliesMy goal is to create an eBook that I can read with the Mobipocket reader on my Blackberry. The problem is that my text includes UTF-8 characters which are not supported on the Blackberry, and therefore display as black boxes. The eBook will contain a list of English and Punjabi words for reference, such as:[code]One thought I had was to write the list to an HTML table with the Punjabi converted into a GIF or PNG file. Then include this HTML file in the eBook. All of the words currently exist in an access database, but could easily be exported to another form for input to the generation routines.Using VB, VBA or C#, how hard would it be to write a routine create the images and then output an HTML file containing the English words and images in a table

View 6 RepliesI am new to Visual Basic 2008 and NET and am using the Visual Studio 2008 Express editions. I recently downloaded the ebook "Build a Program Now!" for VB and have been working through it without problem until te end of the penultimate chapter 8.
Part of the exercise includes the following code:
Private Sub tsbFilterByMake_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tsbFilterByMake.Click
Dim filteredByMake = From Listing In Me.CarTrackerDataSet.Listing _
[CODE].........
Whenever I attempt to execute this code, I get the error "The method or operation is not implemented" on the last line before the End Sub. This suprised me because when I typed in the f after the = sign, Intellisense offered me the single choice of the required filteredByMake, suggesting to me (in my probable naivety) that it recognised it as a syntactically corrrect choice. This is not down to an error on my part somewhere in attempting the exercise as I get the same result trying to run the Complete code solution that accompanies the book. I have successfully replaced this and a similar Sub with SQL queries on the datasets in question, why the above code does not work and what can be done to correct it.
I am using VB Express 2008, and I'm experimenting with querying WMI. I have tried the code samples from MSDN, but they do not compile. Here is an example of code that my IDE doesn't like:
Imports System
Imports System.Management
Public Class Query_SelectQuery
Public Overloads Shared Function _

In this case, SelectQuery and ManagementObjectSearcher are underlined with squiggly blue, and it doesn't know what these are. What am I missing here? Please help, because I'd love to be able to write console apps that query WMI.
I am using vb 2005 and need help with trying to do the following :A Form that has a combo box , a listview and 2 command buttons( When the form loads ) i need the combo box to be enumerated with the printers that are on my server ( so will need to connect to my server which is obviously a remote machine ).Then when ever I select a printer from the combo box, it enumerates the listview with any print jobs that are in that printers que and I am able to select either one or multiple print jobs and click on the cancel print job button ( which will cancel any selected print jobs ) or click the cancel all button which will just delete any print jobs in that printers que.I know this is a lot to ask but even if I could just get an example of how to enumerate the printers into the combobox and get the listview to display the print jobs ( If any exist ) for that specific printer.That would be great.

View 5 RepliesComing from more low-level languages like C++, and seeing how transparent .NET memory management is, I've got a concert about a piece a line of code I've written. In C++, every object necessarily (dictated design practices and peculiarities of memory management) needs to have a constructor and a destructor. In .NET, destructors aren't needed as often, and there are different patterns of when they are required and how to use them. My question is this. If I have the following like of code (in VB.NET, but equally applies to C#)

I'm trying to write some code that can read events from another computer's event log. I haven't used WMI or System.Management all that much before this, and despite all the examples I've found on the web (there's a lot), I cannot authenticate to another machine.
No matter how I tweak the code, I always receive a System.UnauthorizedAccessException in System.Management.dll. (The message is "Access is denied.

I want to learn by resolving a problem i have been having with my small car hire business.
I want to develop a system which will enable me manage the business efficiently, the solution should be able accessible to more than 1 users, on my LAN and i would also like to have a web reservation system.
How easy/difficult is this when using VB.Net and what things must i do at the onset to achieve my goal.
I've been trying to develop a VB application which retrieves a lot of information from an XML file on our secure intranet. So far I've been using...
Dim request As WebRequest = WebRequest.Create(xmlUrl)
request.Credentials = New NetworkCredential(username, password)
Dim response As WebResponse = request.GetResponse()
Dim str As Stream = response.GetResponseStream()
Where username and password are predefined. What I need is a way of utilising the Windows credential manager to handle this. Ideally, I like it to pop up a credential prompt at application start, and then store the credentials for later use. So far so easy, but I want to be able to use the tick box to save the credentials back to the store, so taht next time the application is used, they are already filled in.
So far I've been investigating the CredentialsDemo from MSDN, but have been unable to adapt the routines to a web request from the given example of a SQL request. In fact I've not even been able to get the demo working adapting it to my own SQL server!It utilises the CredUIPromptForCredentials function. Is this the right way to go? Or am I barking up the wrong tree?
