No Tag For XML File Element - Method Call Fails
Oct 27, 2010
I have this method:
Private Sub SetIfNotNull(ByVal input As Object, ByRef destination As Object, ByVal ConversionType As ConversionType)
If input IsNot Nothing AndAlso input <> "" Then
Select Case ConversionType
Case DealerTrackConnection.ConversionType._String
destination = input
[Code] .....
And here is one call in which it fails:
SetIfNotNull(ApplicantElement.Element("suffix").Value, NewApplicant.Suffix, ConversionType._String)
If the element from the XML file is nothing (there is no tag), the method call fails. but I am checking for nothing.

I have a self-hosted WCF service (VB) residing on a server. This service has a method, which I call from another application, that is supposed to kick off a .cmd file which calls a 3rd party program.
My WCF has used both the old Shell() command and the Process() object. Both can call the .cmd file (located on the server's local drive). The .cmd file looks like this:
CODE:
Now I know the .cmd file (saved as Letter.cmd) is firing because when I check the txt file after testing my app, the before/after statements have been written. However, the 3rd party application does not start.
Now the weird part -- if I double click the cmd file from explorer, the test statements are written to the text file AND the 3rd party application kicks off. Runs great.
I've double-checked the application and corresponding files to make sure NETWORK_SERVICE has permissions and my service is running under that account.

I am adding a web interface (ASPX.NET: VB) to a data acquisition system developed with LabVIEW which outputs raw data files. These raw data files are the binary representation of a LabVIEW cluster (essentially a structure).LabVIEW provides functions to instantiate a class or structure or call a method defined in a .NET DLL file.I plan to create a DLL file containing a structure definition and a class with methods to transfer the structure.When the webpage requests data, it would call a LabVIEW executable with a filename parameter. The LabVIEW code would instantiate the structure,populate the structure from the data file, then call the method to transfer the data back to the website.
How do you recommend I transfer (copy) an instance of a structure from one .NET program to the VB.NET program that executed it?

I have a simple login field, which works fine with the exception of one quirk. The form is set up with the tab order to go to the UserID first and the Password text box second. This works fine when the form is used the first time, but when the form is used the second time the focus in placed in the Password field. If the form is used a third time, focus is moved the OK button, that is each time moves to the next tab order. I even tried to set the focus in the Load event as in Me.txtUserID.Focus(), but this doesn't change the behavior. Again, I should note that I close the form and not hide the form.

I have a class that runs as a thread. While the thread is running, I want to call a method in that thread. I do this commonly where a thread calls a method in the GUI with a delegate. But I'm confused how to do this when the called thread is not the GUI and there are no parameters passed to the called method.

may I just ask a seemingly simple question for which I can't find any solution throughout all the VB.NET documentation: I have to call a (non-static) method of another object (instance!) based upon the name of the method (given as a string).

I want to call this method from C# 3.0 and I want it to use its default arguments. I tried passing System.Reflection.Missing.Value, but I cannot cast it as String. Is there any way to do that?

I have a method called ADD in a class that connects to a database. The database class name is XDB. I also have an object named XXX in it's own separate class with properties.One of the instructions for the Button named ADD click event is:
'Call Add method passing in the XXX object
So this is how I coded:
'declare a variable X as an object instance of XXX
Dim X As New XXX[code].....
I know it's wrong since it doesn't add the XXX and the form doesn't close but I don't know what I'm doing wrong.

REF: http:[url].....The above reference is where I got the code below.This code adds buttons to Form1. When a button is clicked a messagebox appears stating what button was clicked. I want to have the ClickHandler fill a RichTextBox on Form1 (I added a RTB to Form1). My problem is I can't do a Dim xForm As New Form1 to fill the RTB from the ButtonArray Class. I can place my file's text in a MessageBox so I know the code I added is correct. I also tried placing a Property method on Form1 and using a Accessor to fill the RTB, however it also requires Dim xForm As New Form1. How can I get my data from files to the RichTextBox on Form1 from the ClickHandler in the ButtonArray Class? See ButtonArray Class Below.

I have a asp.net web application with jquery controls. I have a datagrid that will display data from a database table and created a WCF Service to access the db and return the data. I want to be able to call the WCF service from this application which is on a different server and have the xml data returned, converted to json format to be used in the datagrid which is a jquery widget. I have tested the web service and it works fine. Should I call the web service from the javascript function within the xml or create a .net method behind that calls the service and then does the conversion? From these how would I get started?
