I am having problems deserializing the response message I receive from the proxy class I created through WSDL.exe. I believe the problem lies in the fact that I am using XmlArrayItem, which has nested items within.Instead of getting:
<results xmlns="urn:partner.soap.company.com">
<result>
<created>false</created>[code].....
I am trying to created nested dictionary variable like the below, But I get compile error stating that it needs "}" at line where I am adding items (line #2) to my nested dictionary. What Am I missing here?

View 4 RepliesI'm gathering a list of files within a directory and then adding them to a ListView:
VB.NET
For Each f In Directory.GetFiles()
Dim lvi As New ListViewItem
lvi.Text = f.Name

The exclusion list works great, but it duplicates each item in the ListView several times. How many depends on how many items that it excludes.
I understand why it's happening, but I can't figure out a way around it. I have to loop through the items in the ArrayList so that I can compare them to the other items.
I'm trying to use a nested multi-line lambda Function in VB.NET and am getting an error. Here's what my code looks like:

.Select(Function(k)

I'm using a series of nested if/then/else statements to make sure a user enters information into each text box or chooses a radio button. What would i use to say if no text is entered in textbox1, then ... also what would i use to make a sure the user choose one or the other radio button? for example i also have a combo box, i used "If SubjectComboBox.SelectedIndex <> -1" for the if statement.
View 2 RepliesSome code first..this is how i deserialize..This part works.
Dim rdr As XmlReader = XmlReader.Create(New System.IO.StringReader(Replace(prestr, "><", ">" & vbCrLf & "<")))
Dim serialize As XmlSerializer = New XmlSerializer(GetType(ItemLookupResponse))
Dim myProduct As ItemLookupResponse = New ItemLookupResponse
myProduct = CType(serialize.Deserialize(rdr), ItemLookupResponse)
I have a Child class which uses DataContractSerialization and raises a Changed event when its Name property is set.
<DataContract()>
Public Class Child
Public Event Changed()
The Parent class is serialzed and deserialized and all the data (including the Child) is saved and resored as expected.However, after deserialization, the Changed event is never raised!I know the deserialization process bypasses class constructors, but shouldn't the event be initialized?Is it possible to serialize/deserialize the Event?Is there a way to initialize the event in the OnDeserialzed method of the Child rather than the Parent (see below)?
(1) Add a constructor to the Child class which takes an instance of itself as an argument.
(2) Add an OnDeserialized method to the Parent class which creates a New instance of the Child class based on the deserialzed instance of the Child class.
<OnDeserialized()>
Private Sub OnDeserializedMethod(ByVal Context As StreamingContext)
Child = New Child(Child)
End Sub
Now the Changed event is raised as expected.

View 4 RepliesI am trying a simple object deserialization from an object encoded as a Base64 string, but I keep getting this weird error message.

To object oriented programming and programming with visual basic .net (vb 2008 express). regarding storing of information but not in a database. Someone mentioned using binary or xml serialization. So I researched that and after two long 8 hour days of messing around with binary serialization and about a dozen different code techniques i finally found one that seems to work. I created a module that serializes two variables and appends them into a file. The same module also has a sub that deserializes the information from the file and displays in a message box. If needed I'll provide the code later.
Really the problem I am having is that my message box only displays the first entry into the file and no other. So I can append any number of variables to the file but every time I call the subroutine in my module it only displays the first entry. How do you read all of the file? Also can I search the file for a particular value of a variable? The variables are codependent. The two variables are simply a date and a string representing a changing code that corresponds to that specific date. So I'd like to be able to say search for a date and retrieve both the date and the code.
However I don't have any idea how to do this. Also the messagebox.show method is probably not the best way to illustrate the information in the file but I'm still new and I'm not sure the best way to show all the info in the file. For instance if I wanted to show the entire contents or just the codes corresponding to certain dates. I know a database is probably the better answer but I've gotten this far without one, lol, I'm too stubborn to change now. Once I figure this out, I'll switch and try the same technique with a database.
