I am working with VB.NET and I am facing a problem with XML serialization. When empty values exists in the object I am serializing, the XML file contains the following tags:
<tagName/>
instead of:
<tagName></tagName>
I know that it's the same, but I want the start tag to close appropriately.
my class inherits from TreeView. In it's constructor, it adds nodes. In the Winforms designer, if I put an instance of the Treeview on the Form, the nodes are visible. That's ok.

How To Avoid The Closing Of A Combo Box Popup Window In Datagrid? I was trying to block the closing of a custom combo box popup window in my custom DataGrid. The popup window comes by pressing F4 or ALT+DOWN keys which is getting closed if I press the down arrow for the first time after showing the first value in the combo box as selected. Next time onwards, if I press the F4 key and down arrow, I can move to any item in the popup window and select the item using keyboard and in that case, the popup window is not getting closed till I press the ENTER key or selection using the Mouse. Is there any specific reason for this behavior or something is missing in my code part?

With my code as I have a trouble with the returned strings that I have extracted from my php source to add the strings in my listview.
I'm reading the tags of mystrings1 and mystrings2 for each paragraph from the php source. I got the returned strings which it looks like this:
PHP
<p id='mystrings1'>my strings</p> | <a href="http://xfvasfasfasfasf">Link</a> </td> | <a href="delete.php?id=0">Delete</a> </td> | <span id="mystrings2">Enabled</td>
I want the returned strings to be like this when I reads the tags of mystrings1 and mystrings2 while ignore the other tags.
PHP
<p id='mystrings1'>my strings</p> | <span id="mystrings2">Enabled</td>
Here's the
Public Sub timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs)
timer1.Enabled = False
timer1.Stop()

Do you know how I can ignore the other tags when I get the returned strings of mystrings1 and mystrings2?
I am planning to create a system for my case study wherein i can Add tags from images and search for it by "tags" such as photobucket. For example i open an image to my system, and it's file name was "WhiteHouse.jpg" and i added or tagged it as "Building". Once i search on my computer, and type the word/keyword "Building", the image "WhiteHouse.jpg" will be displayed on search results as i tagged it on my system.Is that possible guys? or i can only search by tags using my system/application? and not in the search command in my computer?If it is possible please tell me what to do. or if you have sample vb.net2008(windows Application) files it will be helpful. Or if you have sites related into it. pls send me those links, especially downloadable vb.net files w/ codes for further studying.
View 2 RepliesI have two experimental web services. One is an asmx contained within a .net web application. The other is a WCF service library being invoked from the web application.The asmx basically does everything I need, but I think WCF would be better, except that it doesn't do anything as I would expect after fiddling with the asmx service.For example, the same method behaves differently in each:
' ASMX

Function Test(aObject as Object) as Object

Form1 is a mdi container. It has a bunch of forms that can load inside of it as mdi children. If I close each open form inside the form1, and then click the red X at the top right, application exits fine.If I click the red X without closing the forms inside I get: An unhandled exception of type 'System.CannotUnloadAppDomainException' occurred in mscorlib.dll
Additional information: Error while unloading appdomain. (Exception from HRESULT: 0x80131015) However I can break from it. How do I get the application to not show that error? What must I do to fix those inside forms or close when the red x is clicked?
Dim frm As Form
For Each frm In Forms
Set frm = Nothing
Next frm
The above code is what I used in VB6 to close all forms associated with my programs before my program closed. I have been searching for information on how to make sure all forms are closed when closing a VB2008 program.
I have seen info on using the Project Property Shutdown mode When startup form closes and I currently have this set.
Is this all that is really necessary? Will the garbage disposal close everything else to free up RAM?
Also, if I have several forms open and want to close all from the main form without closing each one individually, what is the best approach? Is there a collection like in VB6, go through the collection, compare it to the name of the main form and close it if it is not the main form?
I have the following code to close a form which is a child. The problem is that when it closes, it closes the MDI parent too.

I have xml like this:

Why is XMLSession.FileList.Count always 0. I hypothesize it has something to do with the declaration above it but I am not sure what is wrong with it. Maybe it can't accept a path, if not, how can I do it?
I've been serialising and deserialising .net objects using the XmlSerializer class without problem, however we now need somebody else to look at that data to perform some analysis on it.In order to help with that we've produced an XSD based on our class like so:
xsd.exe /t:DataClass Assembly.exe
The start of the XSD looks like this:
<?xml version="1.0" encoding="utf-8"?>
<xs:schema elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="DataClass" nillable="true" type="DataClass" />[code].....
Bizarly, the XML produced does not adhere to the XSD generated from the same class.My question then is, is there a way of telling the XmlSerializer to serialize the object based on a given XSD? As an aside, I've looked at other ways of fixing this: I've tried re-generating the classes from the generated XSD - this seemed to have the same problem.

View 3 RepliesI have a base class ("MyBaseClass") in a project called "BaseFramework" which is included in several solutions within the company. There are several derived class's in various projects throughout the company that inherit from "MyBaseClass". If I then create a List and add derived class's to it, it will not serialize. I realise that if I were attempting to serialize this list, and the base class and derived class were in the same project, I could simply apply the "XmlInclude" attribute to the base class and include all of the derived class's. This is however not possible across projects, because that would require a circular dependency.
View 1 RepliesI am attempting to solve the well known problem of automatically generated serialization assemblies in VS 2010, both VB.NET and C#. The "Generate Serialization Assemblies" option in project settings does nothing for non-web projects (see [URL]). Thus the calls to serializers generate file i/o exceptions that are very unfortunate, and for which there is no cure. The method suggested above does not appear to work with VS2010 and SGEN still runs with /proxytypes enabled.

View 2 RepliesI've been cloning my objects using serialization for awhile, and typically its been quick, at least for my purposes. After a series of updates to these objects, however, now the serialization process is much slower. Trial-and-error has so far failed to pinpoint the cause. Some of the added elements to my object are:
1.binding lists
2. an inherited dictionary class
3. more internal references (the object is actually group of nested objects, and these internal objects have more references to each other than before)
I have been careful to avoid/eliminate references to external elements when cloning, as that can lead to a cascade of extra cloning. So I think the problem is with the object structure itself. This is my serialization routine:
Friend Function CloneObj(ByVal obj As Object) As Object
If Not obj.GetType.IsSerializable Then Throw New Exception("Object not serializable")
Dim bf As New System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
