This is really more of an academic question, but where is this function defined? Within .NET, I'm used to working in an object oriented manner. However, if I define a VB.NET class as follows:
[code]...
Is MsgBox defined in a class? I am not required to reference a static class or inherit from another class. I'm not even required to import a namespace. I did find this link from msdn. But my question remains, where is this defined and how does the CLR just load up a function?
I'm trying to undersatnd the syntax of calling a funciton and it seem confusing when I'm using a web service in ASP.net. Maybe this question should be in an ASP forum, but it is a VB question. This simple web service allows you to type in your name and it response with an alert box with you name.
My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for
So I want when you click Button1, it displays MsgBox ("Hello"), when you click again, it displays Msgbox("World"). Then it all starts Hello "world hello world" etc.
I am creating a function and want to have IntelliSense pop down the list of valid options for a certain parameter in the same way that the MsgBox function behaves when you are typing your argument for which buttons you wish to include (such as MsgBoxStyle.OkCancel). I have done my best to search the internet but haven't found a thing which comes close to what I'm seeking. My monkeying around hasn't produced a satisfactory solution, yet, either.
A related additional thing, which I can live without but that would be nice to have, is the description of the current parameter, which appears below the function description as shown highlighted below MsgBox (Prompt As Object, [Buttons as Microsoft.Visual Basic.MsgBoxStyle = MsgBoxStyle .DefaultButton1], [Title as Object = Nothing]) AsMicrosoft.VisualBasic.MsgBoxResult
Buttons: Optional. Numeric expression that is the sum of values specifying the number and type of buttons to display, the icon style to user, the identity of the default button, and the modality of the message box. If you omit Buttons, the default is zero. This is my first post. I'm relatively new to VB .Net.
I'm a new user of VB.Net. I do have doubt on accessing a user defined Function or Sub. In some place of program, I do see the term "Call" when using the Function/Sub. In some other place without "Call". But both works perfectly. May I know the difference between the two.
The main function receives data, uses additional functions to calculates the result and gives it back. But at one point, the function needs data from the SQL Server. I wrote a second UDF, made it visible and deployed it to the SQL Server. I see now two functions under > programmability > functions > scalar value functions:
1. The main function (IsCalcDay) and
2. The function with the data access (IsHoliday)
If I call directly the second function from VST in the debug mode, it works fine, bur if I call it via the main function, the code stops if the connection will be opened. The error is "Data access in this context is not permitted. The context is a function or method that is not marked with DataAccessKind.Read SystemDataAccessKind.Read or a callback to retrieve data from the FillRow method of a table-valued function or a UDT validation method." (translatet from German, probably slightly differnt in English)
VST (2010 prof) and the SQL Server (2008 R2) are running in my virtual W7 maschine.
Here is the code of the second function:
Imports System Imports System.Data Imports System.Data.SqlClient Imports System.Data.SqlTypes
[Code]....
Why can I open the connection if I call the function directly, but it fails if the function is called from another function?
it seems always at this time I cant figure out how to do something maybe it has something to do with lunchtime.
Im having trouble using a method that is defined by an outside company
This is a link to their integration guide:
[URL]
This is their documentation for the class Im trying to use
OrderQueryWebService Class
This class is for SID in particular and is made for use with the notification methods. This is for the Order Query Web Service specifically, allowing clients to return the status of transactions for their merchant, whenever they want to.
Methods / <summary> / Pass through the variables required and receive a list of Transaction objects showing transaction status
[Code].....
The MerchantCode, the MerchantUsername, the MerchantPassword are all good the List is a custom type called SetComHash.Transaction
Everytime I try adding a string to the list such as the transactionNumber and some other values it gives me a type error:
"Value of type string cannot be converted to 'SetcomHash.Transaction'
I am trying to redirect command line output to a list box in a vba macro, and I've found some code that I think might point me in the right direction, but I keep on getting the same error. When I use this code [code]It gives me the error in the title and highlights the first declaration line.What does it take to define a new "process".
I have a Sub() in which I define an array called FileNames(). Within the first subrouting I then call a different subroutine in which I would like to reference FileNames. Do I need to do anything special (such as make FileNames a global array) for these subroutines to have access? Right now it is telling me "Sub or Function not defined"
I am trying to write following expression on a datacolumn. But it results in error:Replicate('*', nLevel) + NameWhere: Replicate() is a user defined function (in a module). nLevel and Name are two other columns in same data table.
I am unable to popup msgbox if count=0. It will work only if i use MsgBox(""). I am unable to understand how it has anything to do with msgbox("")
Private Sub txtstaffID_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtstaffID.TextChanged Dim conn As SqlClient.SqlConnection
[CODE]...
Both IF and Elseif code executes but the problem is the msgbox won't popup in both the cases( i.e when IF executes and when Elseif executes) unless and untill i have a msgbox("") before da.Fill(dt)
If NewEntryName.Text = "" And OpenFileDialog1.FileName = Nothing Then MsgBox("Please choose a name for your game.", vbExclamation) MsgBox("Please find your game.", vbExclamation) Else Button1.Text = NewEntryName.Text game1 = True Panel1.Visible = False End If
I want it to show the first MsgBox if the NewEntryName.text = "" and I want it to show the second MsgBox if openfiledialog1 = nothing... how do I do it?
I want to make an numerical integration method with takes in an analytic function and integrate it over a specific interval. For the numerical integration procedure I want to use some procedures in nr.com. The problem is that these are programmed in C++ and they uses functors to pass a function to the integration method. How can I do this in VB 2010?
I want to initialize the function (i.e. set a=1,b=0 for function y(x)=a*x+b) and then pass the function to the integration method. Then when the integration method call the function it only calls the function with one parameter (i.e. x since a,b is already set)
What is the best way to do this in VB2010?I want to make a general integration method where I can pass any single valued function and integration limits.
I have just started using VB, and from what I have found so far it seems like the tools you have is
- to us a delegate for the function - to use a lambda expression for the function - send a pointer/adressOf - to create a function class/structure and submit this to the function
As for now I am most inclined to create a function-class. But I am not really sure how.F.ex. I make different classes for each "uniqe function" I want to integrate, but how can I pass them to the integration function when I need to specify the argument type in the integration-function-call?This seems like a basic problem which applies to many Math operations, so I think it would be very useful to clarify this.

I am trying to convert a DLL function call which has the Callback function routine called within the DLL function call.The DLL function call signature is like this:

I have pulled some records in DataGridView from database. Now I want that when I select some rows from DataGridView and click on command button, ID's of all selected rows should be displayed through message box.

I am creating a message box in VB8 for an error. I created the message box and everything works. The message box returns a value of 0 which is the default one. Where does it return 0 to. Or do you have to tell it where to return it.
