FORTRAN allows one to use a procedure (function or subroutine) as an argument to another procedure. For example:
SUB Procedure1(x)
----
----
RETURN
[code]....
Does Visual Basic 2010 allow this functionality, directly or indirectly?
I made this procedure re-use a select query:
[code..]
And I use it like this if I would want the selected value placed in a textbox and it works fine
[code...]
However if I want the value to be passed in a string like so:
[code...]
The string ends up having an empty string value. How do I assign the value I queried to that String?
I have a sub declared inside a module which accepts form as argument.
sub display(fname as form)
What I need is to call the sub form the load event of a form.I tried the following.
display(me)
But cant access the controls of the form inside the sub.
sub display(fname as form)
fname. 'no controls of the form are listed?????????????
end sub
Hi. The assignment reads code the application using an idependent sub procedure to both calculate the display the bonus amount. Also use a sub procedure to clear the contents of the bous label when the text change event occurs. In addition code each texts box enter event procedure. When I call the calcbonus, it says argument is not specified for the parameter.

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.)

View 3 RepliesGot a strange one and I know it is something silly but I can't see it for anything I have a DLL created in VB.net (No I can't change it! :-)) and am calling it from C#. The problems come at the point the object is created in C# and I get the message that it has "some invalid arguments".
The constructor code in the DLL is as follows:
Sub New(ByRef Connection As IConnection)
The code in C# is:
IConnection conn = new Connection();
CustomObject test = new CustomObject(conn)
It is happy with the first line but it gives the error message ("some invalid arguments") on the second line. I have also created a secondary project in VB.net and called the DLL and it works fine there.
I have migrated my app from VB6 through Visual Studio 2008 to VS 2010. I have corrected all flagged errors, but I have not made any changes to code otherwise. Now I am getting Error #5 under some circumstances, and the text of the message is as follows:Argument 'Start' is not a valid value.I have done a global find for 'Start' throughout my Solution, but got no hits within my Basic code. Where is this error originating?Why has the pasting of the error text above changed my post's font?

Why is it throwing this error?
I have :

// Give exception = Format of the initialization string does not conform to specification starting at index 62.
When I substitute the actual value of the Resource, it give no exception :
Dim con As New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:
awData.xlsx;Extended Properties=""Excel 12.0 XML;""")

I think this should have been replaced even before the compilation process..
Then why is it giving exception ?

View 3 RepliesI have a form that loads in my project and does some task on its own, then closes itself. I'm implementing a new functionality into the program where I need to call this form with an argument (to later be used as a conditional clause). If I call the form from a certain button, I want to launch the new form with an argument ("automatedTicket") and I will then use this argument as a conditional test in the code of the form.where, in the ACCEPTING form do I put the argument declaration?
basically i need to do something like:
ServiceTicket.Show(False) 'false for being a manual ticket (click of button)
ServiceTicket.Show(True) 'true for being automated (no user intervention)
then in the ServiceTicket form, where do I put that I'm expecting one argument? and where do I declare that argument name (automatedTicket)?

How can I pass a sub address into a subroutine.
I understand delagates but not enough to figure this out.
I have a sub that creates and adds menu items to a menu and I need to use it in more than one project so I want to put it into a library.
But I don't know how pass it the address of the subs to attach to the new menu items.
I am trying to pass an argument to a sub then have it add to my listview, my code is:
Module modFunctionsSubs
'Function and sub routines
'This sub logs an even in the listview

listViewMainLog.Items.Add(statusText)
End Sub
End Module
My argument is getting through ok, statusText but I get an error:

View 1 RepliesI'm using VB.NET 2003 with .NET Framework v1.1. I know it's getting a bit old now but I'm stuck with an existing program and don't have the time/knowhow to convert it to anything newer.
My question would probably be solved very easily with Generics in .NET 2.0 but as I can't use that right now, I'd like to know if the following is possible:
I have a load of manager classes which inherit from DictionaryBase and hold collections of my custom classes. For example, I have a Employee class, a Batch class, a Supplier class, etc... and each of these has a Manager classwhich holds a collection of them - eg: my PlantTrayMgr class holds collections of PlantTrays, etc..
I have one particular form where I have to populate loads of comboboxes with the contents of various Manager objects. What I currently do in my form load event to populate comboboxes is this:

Option Strict On
Option Explicit On

In my vb.net code I want to call a dll file created by Qt4.
Now everything works fine untill and unless I pass some string argument to the function.
Here is the function in dll file:
const char* QtEngineDll::randInt(char url[])
{
QString result;
/*QTextCodec *codec = QTextCodec::codecForName("UTF-8");

When the function returns some constant value, say if i put result = "Abhijit" then it returns the value properly. But if I want result to return value url the it is returning some garbage values.
I have a DLL written in fortran that I know works because I am getting it from a working software package that we use daily. I am trying to call it from anything but am having problems i believe with passing the correctly formatted arguments in and out of it, so i decided to try and access it from a VB program. I chose VB because I have contacted the developer of the software package we are using and he gave me his DLL function call in VB6, even though he is not allowed to show me the FORTRAN source.
Problem is (perhaps, i think) that I am writing in VB.NET, which has different data types than VB6. Can anyone see why i am am having problems. The error i get upon running is: "AccessViolationException was unhandled: Attempted to read or write protected memory. This is often an indication that other memory is corrupt."
