I use Visual Studio 2003, VB.net, NetFramework 1.4 and Windows XP I have been using the following Code Snippet for a number of years in both Web Services and Windows Applications. However suddenly around the 29th September 2010 it has stopped sending E-Mails from both Web Services and Windows Applications. The same problem has happened not only to my own Network but on two other Networks, one using XP as its Server and the other using Server 2003. All 3 of these are using different ISPs.

The form is an About Us form so has nothing on it only a text box and a OK button.
[Code]...
Why won't the button close the form? I'm puzzled, I tried another button just in case with the same result. UPDATE: I set a break point on Me.Close() and it isn't reaching it when I click the button, I created a new button and the same thing happened.
I'm trying to pass a value from Vb to PHP. So far I have used public property to pass a string value to one form to another

I would like the same value to be passed to a php file is this possible?Also I'm using WinForms?
In VB.NET, can we pass an original object as an argument without instantiating it? For example, I have two forms in my project formA and formB. Now I have this code.
[Code]...
Apart from this, in VB.NET in any class like formA, if I type formA, I can see all the objects and controls present there but not in C#. Again, I have to make a new instance to see all the controls. This becomes a problem if I want to manipulate two running and working instances with each other. So what basic thing am I missing here?(I am an amateur programmer migrating from VB.NET to C#. Things are going nice and clean expect for the ones I've recently figured out.)
I am trying to pass a 2D array into a dll I wrote in C. When I run the program, it crashes at the first line (in the dll) that I try to read the array. It gives an error that it is trying to read protected memory. I'm guessing this means the array was not correctly passed to the dll, so the program is trying to read a memory location that doesn't exist. Is the problem somewhere in my VB code? If not, it must be in my C code, right?
Here is my VB code:
Declaration of the function in the dll:
Code:
Private Declare Function image_processing Lib "image_processingDLL.dll" _
(ByRef image_array As Long, ByVal dpi As Long, _
ByVal xDim As Long, ByVal yDim As Long) As result
Calling the function:
Code:
Call image_processing(hImgArray(0, 0), hImage.HorizontalResolution, _
hFilmPictureBox.Width, hFilmPictureBox.Height)

I'm writing a program to control another program using redirected input and output. This is a simple sample of what i want to do that works. But since I'll then be adding other commands and waiting for other responses like username: then password: then. I'd like to put the "wait for" and "send" sections in sub routines. My problem is somehow I'd have to pass a reference to the process or at least sIn, sOut and sLog to those routines and I don't know how. Do I dim the process as global or???

View 6 RepliesI have a question concerning some homework. Here is my answer:
Dim intResult As Integer
intResult= Square(4)
lblResult.Text = CStr(intResult)
Now, if I understand functions correctly, this statement should pass the value 4 to:
Function Square( ByVal intValue As Integer ) As Integer
Return intValue^2
End Function
...and assign it's return value to "intResult".
I am using Visual Basic .NET 2005 and I need to call a DLL made in VB6. Couple of days ago i wrote a test dll in VB6 and called it from VB.NET. I passed an array and another variable. And the dll got it and displayed the values in the array. (I didnt save that code)Now when I am writing it again I am getting an error "Specified array was not of the expected type." [code]If I do not pass array then it accepts but otherwise it does not. The array here is CD().

I'm wondering if is it possible that the events for a certain object will be executed by another events under a different object?For example.I have a button named Button1, and I have a ListView named lstView. What I want is that when I click on Button1, the events that will be executed will be the one under lstView.
Here are my codes:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
lstView_KeyPress(Button1, e) 'This is the part where I don't know what to do.

I have my own little tutorial about passing variables, and if you'll look at the code below, you'll see how I am passing the variable from one sub to the secondsub. Here's my question, how can I pass a value back from the 2nd sub to the 1st? So if I want to sum intA plus intB, and want to return that value to the first sub, how do I do that? [code]

I have written a class library that creates a dll to pass data back and forth within the same compiled instance exe. Is it possble to configure this Class Library in order to pass the data produced in the first instance of an .exe to other instances exe programs written in VB.NET?
My first thought was to add a Module. Older versions used Declare Files. Is there something in the compiler that I should set where the variables point to a specific memory address, or something..., that makes the variable available to other VB programs running in a seperate instance?

I am trying to do a really simple function (atleast it was simple in 6.0)... what I want to do is have two forms. One with a textbox, and one with a button and a textbox (we'll call this one form2). When I add a value to form2 and click the button I want the text to appear in form1's textbox.
My code in form2 is...
' on event button1_click...
form1.textbox1.text = me.textbox1.text
("me" being form2)
Anyways, how to pass a value from one form to another.
I have an old program written in VB6. I upgraded the program with VB 2008. The updated program works fine except when the program tries to transfer an array to another subroutine. The old VB6 program sends arr(0) as an argument to the subroutine, the address of arr(0) is passed to the subroutine. The array arr() address is the first of a block of consequent addresses one by one, arr(1), arr(2), etc.
Now when running VBnet, the address of arr(0) is not the first of all consequent arr(1), arr(2), etc. It is an isolated number, just like if arr(0) were a variable instead of an array. The addresses of arr(1), arr(2), etc do not exist in the subroutine. [Code]
The variable of y1 passes to the subroutine oK, whilst arr(0) passes also like y1 into an isolated address. So VBnet interprets arr(0) like a variable rather than the first value of a long list. I haven't been able to find out why the above sample does not work. I got stuck in my programming effort, as I cannot proceed to to further development. how the code should be modified to enable the whole array information passing through the subroutine.
