2 Errors Converting C# To VB Code
Aug 15, 2012
I'm converting some C# code to VB.Net, as it's a language I know better, I've got some code that I can't figure out...
Dim mybtn As New ImageButton()
mybtn.ImageUrl = _imgUrl
Select Case _buttonType
Case ButtonType.Backpage
[CODE]...........
This is giving 2 errors:
Me.btnBackpage_Click = Delegate 'System.Web.UI.WebControls.CommandEventHandler' requires an 'AddressOf' expression or lambda expression as the only argument to its constructor.
And
mybtn.Command = 'Public Event Command(sender As Object, e As System.Web.UI.WebControls.CommandEventArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event.

i have to convert a visual basic 6 program to the visual basic 2008. i used the wizard that is provided to upgrade but that just doesn't work. It comes up with many errors. most of them are End of statement expected and Number of indexes exceeds the number of dimensions of the indexed array. I really don't know what to do with them and i have to fix them in order for it to run.

The information in the (table 6.2) should be read from a file. As an example if the user has $2.35, then the following should be displayed in the list box: "You can purchase one gallon of any of the following liquids:Bleach Milk".[code]

I am working on a project for school and I am encountering several errors in my code relating to the numeric up down boxes I have in the application. I have inserted my code and the error list below. I'm sure that it is probably something really simply but I am learning the language on my own and I am a little stumped here.

I've deleted the original code, but to be specific, when I developed a form using Buttons and Textboxes I didn't place them in any specific order. The result was that as the user clicks the cursor, it would bounce around the page in what would appear to be a random sequence, but in fact was going to the next button/box in order of how it appeared in the code section of the form. Naturally, my first inclination was ..... OK, that's how it's going to be, I'll just cut and paste the code in the order of how I want the cursor to move. What happened was I generated several errors and the file would not compile. I can find no information on how to properly cut/paste code sections without generating these types of errors. BTW, I did try the focus() function and it did direct the cursor to the appropriate box, but it also only allowed 1 character to be entered in the textbox and summarily directed the cursor to the next box.

I am not exactly sure what I am doing wrong. I need to convert Me.xCommissionLabel.Text = Format(Me.xCommissionLabel.Text, "currency") to a toString, so it displays a dollar sign, 2 decimal places. so I did this. Me.xCommissionLabel.Text = commissionLabel.ToString(CType("C", IFormatProvider))When I run the program and input the data I get: A first chance exception of type 'System.InvalidCastException' occurred in Commission Project.exe.

So I've created a very simple UserControl that is pretty much just a combo box that has US States in it and a couple properties to return the selected value as an enumeration or a string, etc.The enumeration and string values I'm using are being referenced from an external library which is working. However, when I add my user control to another project the designer-generated code has errors in it. [code] I would assume that this probably has something to do with project settings or something similar for the user control. The control itself is in a separate project and compiled as a .dll which has been added to my main project's toolbox and subsequently added to my form. [code]

This is my
If CheckedListBox1.SelectedItem IsNot Nothing Then
MsgBox("Your favourites have been saved")
ListBox7.Items.AddRange(CheckedListBox1.CheckedItems)
End If
End Sub
What i want it to do is to add the selected items from checkedlistbox1 to listbox7 (but not remove them all together)
This is my error: Overload resolution failed because no accessible 'AddRange' can be called with these arguments:
'Public Sub AddRange(items() As Object)': Value of type 'System.Windows.Forms.CheckedListBox.CheckedItemCollection' cannot be converted to '1-dimensional array of Object'.

I am working with Visual Studio Pro 2008, and trying to build a Visual Basic project for my College Course. The coursework is not my question, it's not difficult just time consuming. My problem appears to be much deeper, and is certainly causing me to take way more time than I should need to debug and completely random occurence. I don't mind posting the source code but it is rather vast, made up of 23 objects, each ranging from 200-700 lines. I am running Windows 7 Pro x64, and since I need Jet4.0 DB Engine or some such I had to set the compiler to target x86 CPUs. I have my suspicions, and as queried in my topic, I was wondering if VB Designer code can become corrupt or cause funky errors?
The layout I have is something like this:
frmMain
-frmCustomer
--frmAddCustomer
--frmUpdateCustomer
-frmContract
--frmAddContract
--frmUpdateContract
Each steps forward using the ShowDialog method. Initially I thought it was a fluke, but I had frmAddCustomer open and when I closed it (the code simply does me.close, nothing fancy), it jumped all the way back to frmMain, skipping frmCustomer. At first I was baffled, I spent some 45 minutes trying to figure out why. No errors or exceptions, so it didn't seem to be anything wrong really. Since I was building this project in stages I loaded the same form from a previous stage and copied/pasted the new code in. This seemed to fix it, but it happened again after coding for another 30 minutes to an hour. It also isn't limited to that form, I have now experienced the same issue with frmAddContract & frmUpdateContract.

You must revert the change or stop the debugging sessionBasically the assignment is requesting that we build a 'Call Cost Calculator' and since im relatively new to this i've never worked with strings before and also get the follow errors:Warning2Variable 'sCountryBeingPhoned' is used before it has been assigned a value.

I have some code, that I am converting from C# to VB, in the code is the following line.
int index = ((int)document.GetCharAt(wordOffset +1)) % 256
that translates to something like this:
Dim index as Integer = CInt(document.GetCharAt(wordOffset + 1)) Mod 256
The problem is that the GetCharAt() function returns a Char type (pretty obvious from the name). VB throws an error saying that Type Char can't be converted to Type Integer. So my question is, what is the result of the explicit conversion in C# code?
