View 1 RepliesI want to create a windows installer package using visual studio. It is my understanding that there was a simple way to do this in vb6, you could add an installer like you can add a new form.
How can I do this in vb.net? I downloaded and installed the Windows SDK from [url]... because it said somewhere that it could create installer packages and had tools to do so for .net
I wish to develop windows mobile applications, preferably using VB (I 've done this in the past with VB6). What do I need to install? All my searches result in information about using 2005/2008 versions of Visual Studio, which seems odd if Microsoft are pushing to use Visual Studio 2010. I would like to use VS 2010. So, can I develop Windows mobile applications using VB 2010? If not, what version of VS do I need and what language should I use?
don't complicate the issue with a load of flannel. I just want to know that I need to install - this, with this SDK, these utilities and write your software in this language (ideally VB).
My problem is that I am creating system tools for windows with a good gui and I don't know how to start with it. One of my difficulties is making code for calling any window tools for example, defragment.msc, backup, system restore, registry editor(I knew there's already a thread in here but it is closed).In short, I will create a "Utility tools ALL IN ONE" for my project somewhat like a registry cleaner or advance system optimizer and the likes.

View 4 RepliesI have worked out how to pass my custom objects into ASP.Net json webservices. Works a charm. Problem I am having is passing in straight arrays of my custom objects or alternatively passing in arrays that are parameters of my custom objects. So for example...
Public Class WebService1
Inherits System.Web.Services.WebService
<WebMethod()> _
[code]....
Fails with error: The value "System.Collections.Generic.Dictionary`2[System.String,System.Object]" is not of type "WebApplication1.WebService1+Person" and cannot be used in this generic collection. Parameter name: value
So how do I explain to ASP.net that it is infact an array of Person? note: That changing the function to as List(of Person) or ArrayList does work but given that I implement my own custom collections this is not optimal for me.
UPDATE: Ok so what I have worked out so far is that this problem is definitely associated with how the JavascriptSerializer uses the SimpleTypeResolver to resolve types. Basically if I do something like this
Public Function AddPersonList(ByVal PersonList As String) As PersonList
I can recreate the error using the following code.
Dim PersonList As PersonList = jsonSerializer.Deserialize(Of PersonList)(PList)
However when I provide my own custom type resolver along the lines of
Dim jsonSerializer As New JavaScriptSerializer(New MyCustomTypeResolver)
I can successfully create an instance of my custom list.Now I have worked out how to provide my own custom convertor in the web.config file. Along the lines of this....
<system.web.extensions>
<scripting>
<webServices>
[code]....
PSS: I have tried to use the assembly fully qualified name as specified in the docs for the SimpleTypeResolver (SimpleTypeResolver MSDN) but this throws a "Operation is not valid due to the current state of the object." exception - which is an error caused when the TypeResolver cannot resolve the name?
My problem was never passing in a List(of Object) into my webservice (I simply posed the question as such to simplify it for stackoverflow). In such a case I would be willing to completely accept using a Generic List(of) but my problem was actually that one of my custom objects implemented a property with a strong typed List(of) so for example:
Customer {CustomerID AS Guid, FirstName AS String, LastName AS String, EmailAddresses AS EmailAddressList}
which now needs to be changed to
Customer {CustomerID AS Guid, FirstName AS String, LastName AS String, EmailAddresses AS List(Of EmailAddress)}
This is admittedly not the end of the world and is probably better in the webservice context (as you have suggested) but definitely a detriment when it comes to internal application usage of my Collection properties. What this means is that once I have this property I either need to cast it to my CustomCollectionList every time I want to use some advanced feature or I need to implement another property which exposes the CustomCollectionList.

I have an intranet asp.net application and when a page is loaded, i want to log the IP Address, Computer Name and the Windows Account(from active directory) currently logged into the computer from which the page is being accessed.
So far, Im able to get the IP address and computer name but the windows account, am getting NT AUTHORITYSYSTEM
So here is the situation. I have a button on one of my extjs pages. This button opens a child window as a pop-up. This child window has a .method attribute as well as a .ref attribute, and also a .id. I need the functionality to open another window with the SAME template, everytime I click that button.I was thinking set the childwindow .method property to something like 'getWindow', and the .ref to something like 'newWindow' and then create a javascript function on the backend to look something like this:
var myArray = [];
var count = 0;
function getWindow() {

What I'm trying to do is have a login type windows form to take a user name and password then compare these with data in the db then open an admin type form. I've been trying to get this to work for a few days now with no luck, about 90% of the code below is a peice together from various forums trying to get it to work. I no longer get an error 26 connection cant be made or what may have you, but now I get "Login failed for user ''.", not quite should what this means or how to go about it.
Private Sub LoginB_Click(sender As System.Object, e As System.EventArgs) Handles LoginB.Click
Try
Dim con As New SqlConnection("Data Source=.SQLEXPRESS;Database=C: cdb cdb.sdf;")
Dim cmd As New SqlCommand("SELECT Username, Password FROM(Users) WHERE (Username = '" & UserTXT.Text & "') AND (Password = '" & PassTXT.Text & "')", con)

DB has no user/pass needed to open... I think, I didn't set one and the whole app doesn't use one and loads binded data within another form without any problem whatsoever?
I am working on a project that is pretty much done, but I wanted to put the finishing touch on it.I have a shock wave flash object over most of my form, and I load shock wave files onto it so they are accessible from the main flash object.
