Using A .net Dll In C#. Getting 'invalid Argument'?
Apr 19, 2011
Got 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.
Private Sub lVW_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles LVW.Click With LVW 'LVW=ListVew Name LVW.Text = .SelectedItems.Item(0).Text
I create several controls dynamically with the function createControl which returns a control
.... ElseIf objName = "COMBO" Then Dim cbo As New ComboBox
[Code].....
I know that my combobox has 3 items (in that case that the value was 2) I found that I cannot call selectedIndex before create the combobox, but I am kind of confuse here. I tried also to add it to the panel and to the tablelayoutpanel and then set the selectedIndex but I get the same error.
I have a user that is getting a SocketException immediately upon app startup. The really strange thing is that my app does not uses sockets at all.This is the only information that I am getting from {smartassembly}, which I use for obfuscation.
I have a windows form and a webbrowser1. When it first loads, I pass acouple of arguments to the browsers url. Everything works fine until I minimize the form. I get an error: "invalid argument".The strange thing is if I subsitute the "http:[url]... it works.
Dim returnValue As String() returnValue = Environment.GetCommandLineArgs() If returnValue.Length > 1 Then[code]......
hi,i am having a VB application in my system, which runs with absolutely no issues. But when i am running that EXE in some different machine i am randomly getiing a run-time error for a particular form.The error is like :Run-time error '30005': Invalid Argument valueThat particular form have MSFlexGrid and List box.As i cant simulate the same in my own setup, could u pls suggest the possible reasons?
Actually we have a system for doctors in dispensary and when they try to access records for the patients from doctors module they able to do it but when they try to modify records and save it gives an error "Run-time error '5': Invalid Procedure call or argument" We are using oracle 8i as database and vb6 as fronend.
I have read through many of the questions related to my situation but I have not found one that does. I currently have a repeater with 4 bound items to it, clicking on a button in the repeater causes my error, below is the markup and codebehind. Can someone explain to me why this is happening and the fix for it? (I have excluded the page decleration and just included the page_load event. let me know if i should cut and past full code in)
My goal is to have the user be able to click the row and the row will be the selected row almost like having the select button but the entire row clickable to do the same thingthe error i get popups when i click the row, not when the webpage is loaded
this is the onrowdatabound portion i just added that causes the error If e.Row.RowType = DataControlRowType.DataRow Then ' Get reference to button field in the gridview.
I am getting an "Invalid Arguement" when performing range.find. It doesn't like the SearchOrder argument.I want it to be xlByColumn which is "2" according to my help files.Here is what I have:
Dim row As DataGridViewRow = MainDGV.Rows(i) Dim Frow As Object Dim rg As Object rg = SiteSpreadsheet.ActiveSheet.Columns.Range(SiteSpreadsheet.ActiveSheet.Cells(2, 1), _ SiteSpreadsheet.ActiveSheet.Cells(rowCt, 1)) Frow = rg.Find(row.Cells("SITE").Value, rg.Cells(1, 1), , 1, 2, 1, True)
I have a little program where the user can select an item out of a listview. In this particular listview there is this code under the listboxindex changed event:
Private Sub Lopd_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Lopd.SelectedIndexChanged opdrachtgever = Lopd.SelectedItems.Item(0).SubItems(0).Text
My console errors out when I enter anything other than a number or operators in the designated (input). I stink at this stuff but I have been t this for about 8 hrs. still not there. I have included a text file for the task at hand
I'm using WMI code and VB 2008 to see NIC status. So far the queries are working, but the methods aren't. For example, I'm trying to set a network card to use DHCP, I get invalid function with this code:
Dim classInstance As New ManagementObject("rootCIMV2", "Win32_NetworkAdapterConfiguration.Index='7'", Nothing) Dim outParams As ManagementBaseObject = classInstance.InvokeMethod("EnableDHCP", Nothing, Nothing)
I'm getting Invalid column name 'CHARLES'. Invalid column name 'CHARLYN'. Invalid column name 'SMITH'.what's wrong with my code, it's been a long time since I used SQL dataset. I'm into LINQ but I'm having problems with this kind of LINQ query so I'm reverting to SQL dataset.here's my code:
'Set up a data set command object. Dim sSelectColumn As String = ("SELECT * FROM tblScanned WHERE LastName=" & sLastName & " AND FirstName =" & sFirstName & " AND MiddleName =" & sMiddleName)[code].....
where I was encrypting the string and passing it to another web page to decrypt and get the ids to be displayed as a pdf back to the page. I kept getting an invalid "Invalid length for a Base-64 char array". It was then I realised that the string was getting truncated and that the IE Explorer had a size limit for the number of charaters being passes as a querystring.So I think I need to go the route of posting it.But not sure how to go about it.
Private Sub GetReport() Try Dim hawbs As String = String.Empty[code]....
The retrieve document then does: the decrpytion gets the data(ids) and pulls the pdfs.
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.

error BC30455: Argument not specified for parameter 'pTools' of 'Public FunctionfragPacket(ByRef pTools As Object) As Integer'.!I get this code while trying to get something to work.. heres the code
if (pName.Length >= 13) andalso (pName.SubString(0,13) = "actor_display") then dim aid as Integer = pTools.FourByteToNum(pBytes,2) if (aid <= 4000000) and (aid <> ownAID) then

I am currently working on a sample Invoice application. I have created a product class with a constructor and various methods and properties. In my form class I have added dim statements to create variables to hold my product objects and other various objects I have created.[code]....
A fast-food vendor sells pizza slices ($1.75), fries ($2.00), and soft drinks ($1.25).Write a program to compute a customer�s bill.The program should request the quantity of each item ordered in a Sub procedure, calculate the total cost with a Function procedure, and use a Sub procedure to display an itemized bill. A sample output is shown in Fig. 5.26.Coded it out but when I try to break it down to separate functions I keep getting:
Error1Argument not specified for parameter 'CalculateFries' of 'Public Function CalculateTotal(CalculatePizza As Double, CalculateFries As Double, CalculateSoft As Double) As Double'. Error1Argument not specified for parameter 'CalculatePizza' of 'Public Function CalculateTotal(CalculatePizza As Double, CalculateFries As Double, CalculateSoft As Double) As Double'.

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.)
