I just started to build a website using visual web developer 2010 express.I am getting a syntax error when trying to program a submit button...this is the code i have in my Sub menu for the submit button.
Protected Sub Button1_Click(sender As Object, e As System.EventArgs) Handles Button1.Click
Switch(RadioButtonList1.SelectedValue)

I've been trying to solve this problem for quite some time. I have an application that uses the WebBrowser control to provide some navigation capabilities to the user but depending on what website the user is going, there are some syntax errors coming up. These erros would normally not disturb the user under Internet Explorer so I'm trying to hide them some how.
View 3 RepliesMy code is supposed to select the month fand see what product ahas been sold and how much has been sold. It does it but i keep getting a Incorrect syntax near '='. and i cannot fix
CODE:
there are a total of 5 errors with this code.
error 1: Optional parameters must specify a default value - error location "lastEl As object) As Long" - closing bracket is highlighted
Error 2: expression expected - error location "Optional lastEl As Variant) As Long" - where optional is highlighted.
Error 3: comma, ')', or a valid continuation expected - error location "strCycleIDarray As Variant" - where "as" is highlighted
Error 4: comma, ')', or a valid continuation expected - error location "strSearchCycleIDvalueArray As Variant" - where "as" is highlighted
Error 5: Ismissing is not declared and may not be accessible due to its protection level - error location "If IsMissing(lastEl) Then lastEl = UBound(strCycleIDarray)" - where "IsMissing" is Highlighted.
I dont have an idea where to start solving these errors and i cant debug this search as the errors are there.If you dont understand the errors in the format i have put them in just copy and paste the code into a windows form using a button as an activiator.

I am not certain how to do this, but it seems like it should be easy to accomplish.I have four radio buttons that I want to assign answers to, one of which will have the correct answer along with three other answers that have incorrect answers.The answer button I want to set up as a randomly assigned button, with the other three assigned after the fact.'This code works fine to assign it to Radio button #1.rbGenericName1.Text = m_dtDrugs.Rows(DrugNum) ("GenericName").ToString()I want it to be a randomly assigned button, where the location that the "1" is residing, is a randomly assigned value between 1 & 4. Here is what I have so far, but it has a Syntax Error.
rbGenericName & RndNum & .Text = m_dtDrugs.Rows(DrugNum) ("GenericName").ToString()I know that the above code is not correct, I am just trying to represent what I am trying to accomplish. I already have a random number generator in place, I am just looking for the correct syntax.

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.

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]

Use code tags when posting your code. Code tags are used like so =>
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.
After upgrading to .net 4, my project is throwing errors everywhere I try and change the Foreground Color in code. It works fine in .net 2, 3 and 3.5
