I am getting two errors for "expression is not an array or method, and cannot have an argument list," When debugging, the formula works quite well. However I will lose points for blue squiggly lines. I am not allowed to use any built in functions like math.

i have these 3 sets of code that are giving me INT() errors. Error: Expression is not an array or a method, and cannot have an argument list.

Super newbie here and I recently signed up just to address my problem. Please help me convert or at least tell me what to do on the following code to my vb2008.I saw this listing on a website and I like its simplicity. It was written in vb6.
here's the snippet:Design the form. Create a Command Button named as Command1 and copy that and paste it 11 times. This will create a control array.Then assign the text naming it 0-9 plus (.)dot and they are under one control array. Likewise create cmdOperator control array for the operators Add, Subtract, Multiply and Divide. One button for equals and one for clear. All in all 17 buttons. 1 textbox serves as input and output.
Sorry if I'm in a rush here( I am already) but vb2008 its hard for me to learn control array. I have read a few post awhile here dealing with arrays in vb2008 but I'm overwhelmed with info and confusing for me to grasp the idea.

IM doing an assignment for college. ITs saving records to a file, and getting them back basically. So really not that hard.
The error is occuring around the following line of
[Code]...
basically all I've been doing so far, is formatting the output fields to show dates correctly. And I believe I'm getting this error. There is data in the form becasue i wrote it there to test it.I think im saving this right, but it seems ODD that its not working for me.
I have been working on this project all night and think that sleep deprivation is preventing me from figuring this out. I have a base class from which 5 derived classes are under. I am getting an error in the HourlyWorker class that I just can't seem to get past. The error I am getting on the 2 highlighted in RED "wage": Expression is not an array or a method, and connot have an arguement list
I checked the MSDN and it says to correct the error to remove the arguements list. This is confussing because I need it to validate wage > 0

Why does this:Private [Function] As Func(Of Double, String) = Function(ByRef z As Double) z.ToString
gives the following error:Nested function does not have a signature that is compatible with delegate String)'.
While this:Private [Function] As Func(Of Double, String) = Function(ByVal z As Double) z.ToString
Does not? (The difference is ByRef/ByVal)
Furthermore, how might I implement such a thing?
I got this Error. below is my code.
GenerateTheList is function.Need help

Consider a MyForm class that contains a shadowed implementation of Show(). It also contains a CreateForm() method, which accepts an instance of the form and calls the shadowed sub:

Ok so I have alot of plans for programs coming up and I want them all to fade in and out so instead of copy and pasting from project to project etc I learnt about dll's
So when I added in the references etc and I typed in what I declared the Fadein function as which was "FadeIn" I got an error saying it needed to be declared
So I declared it as a string
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim FadeIn As String
FadeIn(Me)
End Sub
Then I get a different error saying Expression is not a method.
im migrating from vb6 to vb.net and have only very basic knowledge of .net. now i upgraded one of my projects, in which i had function cleartexts() which would clear all the text boxes of the forms. now to upgrade it to .net i converted it to sub (as it didnt return anything), so it looked like,
public sub cleartexts()
for i = 1 to 24
text(i).text=""
next
end sub
but .net 2005 gives the error, "expression is not a method", how do i call it then?? or what modifications do i need to make?

View 2 RepliesThese are the directions for the assignment.So far I am able to get the file read and printed onto a list box.The book we have for the class does not clearly talk about using the array of structure method with formatting an imported text file.After that I'm pretty much having a bit of trouble with everything else.I know I can figure most of it out but what I'm having a big amount of trouble with is the array of structures that he wants.I know that when I have the file imported that I need to save it temporarily and go through it and at every ":" put it in an array and save that spot and then keep scanning through the file. I know it is going to be a for loop using the index to count through but I'm not sure if how to start it.This is how the text file that he wants sorted out looks.

I just have a short question about adding an destination methode as variable argument into my calling methode.
I want to send a "TextChanged" event to a special textbox. But I want to have a "variable" in my methode to add the handler to the textbox. Because it is possible to change the textbox and then I can change the handler where the "Changed Events" should be routed to.
can you replace the questionmarks below??

I have some code in c#
BeginInvoke(new MethodInvoker( delegate() {myAppMethod_Tick(sender, e); }));
Now, When I tried to convert that code to vb.net I have below..

I work with C# 99% of the time. However, I'm having to update some legacy VB.Net code and encountering an issue with VB.Net code syntax. The error that I get is "ByRef" is underlined and "Expected Expression" tag shows up when you hover over "ByRef". The "FooDetail.Load" function is written in C# and expects a List object passed as reference. Don't have any trouble using the same function in other C# classes. Can someone indicate what is wrong with below VB.Net code.
Dim FooDetail As New clsFooDetail()
FooDetail.FooID = FooID
Dim lstFooDetail As New List(Of clsFooDetail)
FooDetail.Load(ConnectionString, "Stored Procedure", ByRef lstFooDetail as System.Collection.List(Of(clsFooDetail))

View 1 RepliesI have a class and method exposed to a client asp.net app. The class looks like
<DataContract()> _
Public Class Class1
Private v_string As String
Private v_integer As Integer
[code]....
The method is declared as
<OperationContract()> _
Function GetStuff(ByVal bar As Class1) As String
In the client code I create an instance of Class1 and set the values for v_string and v_integer, but using Wireshark to look at the xml being sent to the server only a value for v_string is being sent as part of Class1. I'm guessing this is because it considers the value of v_integer to be null/not set. Here is an example of the client code.
Dim MyService as New Service1.ServiceClient
Dim test as New Service1.Class1
test.P_integer = 1
[code]....
how different types are passed/used since Integer is a intergral type and String is a class, but can't seem to work out what to do to fix the problem.
I have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?

I get three errors of expression is not a method
The code below is used to check if the application setting, an arraylist is populated or not via the count method.
When running the program fails with error "NullReferenceException was unhandled" as initially the setting (arraylist) will contain no values.In similar circumstances I would declare a new instance of the object or set value to string.empty or check if DBNull.
I know application settings have a save method but to reference/load them one is not needed.I also left the value field in the projects -> settings to be empty.[code]...
