Private Function CheckForNull(fieldvalue As String) As Boolean?

Apr 2, 2010

How can I create a function from this example:

Private Function CheckForNull(fieldvalue as string) as Boolean

That checks that all my fields are not empty? For example, say I have three fields txtFirstName, txtLastName, and txtAddress. How would I write the function above that would check that these fields were not left empty?

Function Return A Value Byref Instead Of The Default Byval?

Jan 18, 2012

Can a function return a value byref instead of the default byval? That is to say, allow me to directly edit the variable that it is retrieving instead of just giving me a copy of that variable.Right now I'm trying to write a function that will return, based on what the user has selected through a combobox, a particular setting (eg. My.Settings.somethingHere). I then want to be able to edit the setting directly through just calling the function. Is that at all possible?

Function That Takes ByRef Parameters Using Control.Invoke ?

I'm currently invoking a function that takes ByRef parameters using Control.Invoke (which I notice specifies the Object parameter array to be ByVal) but the array of parameters I give it isn't updated by the function. Is this possible with VB.Net 2003 or must there be some error in my code?

WCF Service Generated Proxy Class Exposing Function As ByRef Sub

May 23, 2011

I have a WCF Service exposing a single contract and operation:

<ServiceContract(Namespace:="ImageSystem")> _
Public Interface IUploadService
<OperationContract()> _

[Code].....

This subsequently leads to stream casting issues, because the generated function allows me to pass a memory stream as an input (which works correctly when passed through to the service), but instead of passing me back a new stream for the response, it attempts to cast the MessageBodyStream received from the service into my memory stream.

This is, in some ways similar to other posts but as you can see, there are no enums involved in my contracts - presence of Enums caused strange proxy class generation is marked as the answer in the similar post.

Is there anywhere I configure the proxy behaviour to use the contracts I've specified? Clearly I'm within a dev/test environment currently, but when this eventually goes to production it will be memory and file streams passed to the service, and the returned stream can be in any format to be honest, I intend to treat it as the abstract stream class. The only way round this I can see right now is to change my in stream to be the same as the anticipated out stream, but surely there is a better way?

.net - Get The Memory Address Of A Byref String Reference?

Mar 15, 2011

I am experimenting with more effective ways to generate forms. My experiments goes into the possibility to link strings, and other types, directly by their class reference and use it to update the original values without any strongly typed code.

I have been using GCHandle.AddrOfPinnedObject to get the memory address of the string, but it gives the the memory address of the string data, not the string class/reference that i need to change to allow me to use this approach.I am aware that strings are immutable and can not be changed (Actualy, you can, but its not recomended), but I do not want to change the actual strings, but change the reference to it (the string object).Is there some other way to get the address of a string object reference?

VS 2008 Private Function With A Loop?

Aug 20, 2009

i made this code

VB.NET
Dim iString As String
If My.Settings.IPBank.Count = 30 Then
MsgBox("You alredy have the maximum amount of IP Addresses stored, delete one to add another.", MsgBoxStyle.Information, "Program Error")

[Code]...

I want it to check all of the items in the my.settings.ipbank which is a stringcollection. Before it adds and if it already exists in my.settings.ipbank then i want it not to add it. But it just adds when i run it. And then once its added it says: "Collection was modified; enumeration operation may not execute." But also before i run it. There is a warning saying: Function 'AddTo_IPBank' doesn't return a value on all code paths. A null reference exception could occur at run time when the result is used. Is this something to do with it? I think i have the Next in the wrong place .

Inheritance (Private Overrides Function) - Create A Class And All Other Classes Inherit From It And Modify It A Bit

Oct 15, 2011

I am cleaning up some code and I have multiple classes that are 99% exactly the same. So my understanding is that my options are...

1. Create a class and all other classes inherit from it and modify it a bit

2. Create an abstract class and all classes inherit from it and modify a bit ** I took this route

3. Create an interface and all classes Implement that interface.

Here is my 'original' class below (the one that all of them look 99% identical). This class is used in an arraylist so I have a listing of all my images from a folder I have searched.

Some programs implement command parameters, Like my favourite computer game - Crysis - has them and windows media player has them.But how could i implement them in VB.NET..I want to have a component of my program built as a seperate exe - so it can be an Optional component.But of course the seperate exe, on load, needs data passing to it.So i need something like Process.start("Componentname.exe", "/StartDL <Suchandsuchastring>)/StartDL will need to call a function, and the string that it uses will be given to the function to initiate a download?

String Concatenation String + Function Output + String = String + Function Output And No More?

Feb 4, 2010

The following output produces a string with no closing xml tag. m_rFlight.Layout = m_rFlight.Layout + "<G3Grid:Spots>" + Me.gvwSpots.LayoutToString() + "</G3Grid:Spots>"

This following code works correctly

m_rFlight.Layout = m_rFlight.Layout + "<G3Grid:Spots>" + Me.gvwSpots.LayoutToString()
m_rFlight.Layout = m_rFlight.Layout + "</G3Grid:Spots>" 'add closing tag

What's going on here, what's the reason the first example isnt working and the second is?

The gvwSpots.LayoutToString() function returns a string.

Private Declare Function BlockInput Lib "user32" (ByVal FBlock As Long) As Long?

Dec 26, 2009

In Visual Studio 2008 I am using :Private Declare Function BlockInput Lib "user32" (ByVal fBlock As Long) As Long To stop input from occuring during a search-replace operation.

BlockInput(True) ' do not allow input during search and destroy
Dim cursorIcon As Cursor
cursorIcon = Cursor
Cursor.Current = Cursors.WaitCursor

Then setting it to false at the end of the operation. It did not work, so I thought maybe it was because I was calling it from a child window, so I created a function in the mainwindow, and ran it like this:

FrmMain.BlockFrmMainInput()With these functions is the Main window:

[Code]...

It did not solve the problem. I thought maybe it was because I was running under the debugger, so I tried compiling and running it debugger-free, but that did not do any better. I am still getting input when I double-click the mouse on either form.
