Actually, it's not a problem with VB.NET. You would have the exact same problem with C# too.
This is beause your not following proper OOP coding practices to get what you want done.

I have a problem with enumerating a list box with the available papers sizes of a printer. I want to be able when i click on the printer combobox the listbox to be able to fill with the available paper sizes. So far it seems that it's able to find only the default paper sizes.
I have post this question again earlier on but it was lost in all the new entries. I am really lost of what to do . Any help will be much appriciated. Thank you in advance...
Here is the code so far. cmbPrinter = combobox of available printers.
lstPaper = listbox of available paper sizes.
============================================================================
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim objPrint As New System.Drawing.Printing.PrinterSettings
Dim strItem As String
Dim strPrinters As String
For Each strItem In objPrint.InstalledPrinters
cmbPrinter.Items.Add(strPrinters & strItem)
Next
End Sub
Private Sub cmbPrinter_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmbPrinter.SelectedIndexChanged
' Add list of supported paper sizes found on the printer.
Dim searchstring As String
Dim SearchChar As String
Dim MyPos As Integer
Dim i As Integer
Dim pkSize As System.Drawing.Printing.PaperSize = Nothing
SearchChar = "A4"
For Each pkSize In printDoc.PrinterSettings.PaperSizes
lstPaper.Items.Add(pkSize.PaperName)
Next
For i = 0 To lstPaper.Items.Count - 1
lstPaper.SelectedIndex = i
searchstring = lstPaper.SelectedItem()
MyPos = InStr(searchstring, SearchChar)
If MyPos = 0 Then
lstPaper.Items.Remove(0)
Else
paperToUse = searchstring
End If
Next
updateDisplay()
End Sub
I can fill the combobox of the printers and the list box of the papers. BUT when i click on another printer the program DOSEN'T give me the list of the paper sizes on the new selected printer. It's like it stucks in the paper sizes of the default printer...
HEEEEEEEEEEEEEEEEEEEEEEEEEELP!!!

Do hotmail and yahoo expose their mail functionality to this sort of program ? I'd guess the best place to find out is hotmail and yahoo.

I am not sure that they do. but there should be work arround as we can check the mails through browser. now just it has to communicate with my app or something like that any one please??

If they don't expose that functionality, then you need to control IE and get it to click on each new email, grab the text from it, and copy to your app. Sounds like a lot of work for little reward to me, and as soon as they change the pages, your app won't work anymore.

I am working on a project where the DataLayer and Business Objects will be written in C# and the UI will be VB.Net and or ASP.Net.
For testing I have created simple c# class and collection class.
Both objects are under the same namespace
I compiled them using the build option in the IDE.
In VB.Net I have referenced the c# dll and used imports.
The intellisense work and I am able to see the namespace and my objects.
When I use the following code:
Dim oWidgets As New Widgets ' the collection
oWidgets can not be used (intellisense does not work)
and there is syntax error line under it. When I hover over it i get 'declaration expected'

Why would you do such a thing ?
ASP.NET requires you use VB.NET or C#, it's not a different thing altogether.
hagridcracker wrote:

Does it compile/run ? Maybe intellisense is all that is broken.

Does Widgets have a public default constructor ?

Why do such a thing...
I've jsut started coding in both VB.Net and C#.. just nver used one with the other yet. I've been coding in vb 3-6 since 93' so I am very familiar with OOP..
Short Rant:
Also if you are lucky enough to get a gig with Microsoft or a contract they usually (as in 99.9% of the time) require all coding to be in c# whether it is a stand alone app/part of a solution or if you are doing asp.net coding...
there are more short term vb.net gigs than c# and c# pays better, but doing the ui in vb is much easier faster.
-- Nope it will not compile
-- if you mean the Wiget() method of the Widget Class yes.

Would I invoke a holy war if I said I had no idea that VB had any OOP support before VB.NET ? I didn't even think it had classes until recently ?

So why not do it all in C# ?

Ah.... Yeah, I had to fight not to do my last contract in VB.NET. I just flat out refused, and they took me anyhow.

There's some justice in the world then....

Why ? I seriously find that incredibly hard to believe.
hagridcracker wrote:

Yes, that is the default constructor. Then I have no idea why you'd have that problem, sorry.

I got into objects seriously around ver 6 i believe they have been around since ver 5.
the ui... there are a few gotchas that will get you coming from vb6/vb.net. nothing major but a bit confusing when you start out other than that the coding now is so similar, but just different enough for not so serious developers to think that its hard.
The bulk of my code is in the datalayer and business objects anyway at this will be in c#.
I leave my customers with dlls they can just reference and use.

Hi
You were not specifying that where the Widgets class written. However I guessed it has been in C# class library. I am sure that it was the problems of namespace.You please verifiy the code file that contains ‘Widgets’ class definition for namespace declaration.

Both classes are located in the same name space and all are visible using the object browser.

I made a newbie mistake and was wotking in the wrong scope. After moving my code around it works as expected.

 Hi
Can someone help me out with the comboboxes?
I'm trying to make the items that I add thru my program stay in the combobox and I don't know the right code.

What kind of item that you want add. Usually the item in the combobox just present during the time that you run your application (store in memory). If you want to store an item everytime your program load you need to write it in the formload event. If you want it to be more flexibility, you could store the information of the item that you want to add in the text file or database. So when you load your application you can load that item from text file or database in your combobox as normally.

In VB you probably need an instance of the Acrobat View instantiated before calling the file. In vb.net, I just had to address this. Really the simplistic approach is to hyperlink to the filename.pdf file and it will open in your web form window...kind of automagically.
I wonder if anyone can tell me a way to have it open in it's own window, or web form without writing javascript with a new window event firing...I mean open a second web form while keeping the calling web form open??
