VB 2008 Cannot Be Converted To Boolean
Feb 27, 2010
I am using webbrowser control to pull html elements off a webpage from within my home made browser. The browser it's self is actually a bot. Now, I found elements for text boxes and such to login . Now I am trying to get it check the page for certain elements on every load. This way if I get logged out it will auto login. My problem is I am getting "cannot convert to boolean blah blah blah" in a line and after hours of research on msdn and google I can't fix the problem since I am noob. Heres the code. And the error resides on the line with a "arrow" next to it.
Code:
Private Sub Connect_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Connect.Click
WebBrowser.Navigate(AdressBox.Text)
While WebBrowser.ReadyState <> WebBrowserReadyState.Complete
[code].....

From what I read it is a good convention to name a method that returns a boolean value with the prefix of "is" or "has". So in keeping with this convention I am trying to name a method in my program with this prefix but I am running Specifically I have a class called Day. It is a simple class with a few data members and one method that returns a boolean value of true or false. The name of the boolean variable is isSpecialDay. This class has a method called isSpecialDay which takes the date of the day, applies some criteria to the date and then sets the variable isSpecialDay to true or false. My problem is that the boolean variable is named isSpecialDay and so it the method. What should I do?
Public Class Day
Private TheDate as String
Private DayName as String
[code].....

I have a basic bubble sorting algorithm that can sort either A-Z or in numerical order with just the change of a "less than" or "more than". However, I have to use the code twice in order for it to sort correctly.
'Sub Sort(ByVal array As Object)
'--A-Z
If Array(i) > Array(i +1) Then
[code]....
Anyway, if there is a way to do it, that'll allow me to have just one sort instead of having two sorts which use the same sorting algorithm, but just a different comparator.

Say I have a generic list that is a list of a structure.
[Code]....
I always get an error that it's a value and cannot be set. Is there a way to change it without having to make a local copy of the item, then set the item on the list to that local item?

We have an application that was written in VB6 which I am trying to convert to use the latest VB (Visual Studio 2008), mostly because it's not possible to buy a licenced version of VB6 anymore (personally I'd have been happy to just keep using VB6, but without having a proper licenced version of it, we basically had to chance).The VB6 version I could simply tell it to compile the application and it produced the .exe file which I could then copy onto the server where it was running and replace the old version and then run it.
It seems like such simple things are not possible in VB 2008.I have got the application converted, and if I run it through the debugger it is working correctly, but now I need to get a compiled application to run on the server and can't seem to do it.I have tried using the publish application thing, and nothing I try succeeds in getting a working application.

Seen this in
Dim file as FileStream = New FileStream("myfile.text", 0, FileMode.Open, FileAccess.Read)
Dim reader as BinaryReader = New BinaryReader(file)
Dim data as Byte() = reader.ReadBytes(CType(file.length, Integer))
Why is the file.length being converted to Byte, when Integer range is greater, and the code not failing to do so? I don't understand.

I just tried to convert some of my Projects from VB2008 to VB2010 RC, but got compiling Errors while compiling the resX Files. Seems like the reason are ImageLists/Icons, since if I remove them the files compile fine. I already tried to edit the Forms witch are showing the Errors with the Designer. The Designer changed the Content of the resX file lightly, but the error was still present Here the Error(German Version): 'FormsfrmUserTmpBUTable.resx : error RG0000: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.' I recall a similar error in the Beta, but since I can't find it anymore, I guessed it was fixed.

I have a form with 12 text boxes. I'm trying to get the data from those text boxes to "save", and when that form is opened again have the data be inserted back. This form has different time slots so I need to be able to have it save and repopulate based on what time slot I am clicking on. I was going to have it read the data by splitting it with commas, then inserting them back into the correct fields but it's not working. I had it write the results to a text file and they get written correctly and inserted back, but the problem with that is it only reads that text file so every time slot I open up gets the same data.
Below is code I used to get the data when the Save button is clicked. [Code]. Problem is I get an error saying "Char values cannot be converted to Integers" on the first line, the (","c) part.

I have an application that will not load unless my local SQL Server is running on an Vista Home Premium machine. This started after a .Net 1 to .Net 4 conversion. I am using a sub main sub that is not being called (msgbox is not fired when entering the app), however, I see the app through taskmgr with increasing memory usage, but then the app is removed from the list. By design, if the program cannot locate a SQL Server a form pops up with a connection box to locate the SQL Server for the app. How it determines if it has a valid connection is the program looks for a connection string in the registry, then attempts to connect to it, however, none of this code executes because of the failure to enter into the sub main.The two machines I have tried the 32 bit app on
XP Pro: Failed / Using SQL Server 2008 Express
Windows 2003 Server: Works / Using SQL Server 2008 Developer
Both machines have .Net 4 Client Profile with Extended?

This works fine . However , if I change the code to use the Select case statement instead of the If statement :
I get an error upon initializing the form , which says : String "" cannot be converted to type Double . Why is this happening ? The only detail I can add is that this sub is called on the CheckedChanged event of a Check box and of a Combo box . Luckily for me I thought of using the 1st code from the beginning , but on situations like these , changing from the If statement to the Select case is something that most probably won't cross someone's mind .

I'm making a card game and the first thing I'm doing for it is generating a random card. I used an array for the cards (can't think of a better way to assign a picturebox to a card picture other then a huge select case block). I'm trying to split the 2D array into two parts but it doesn't work.
My current
vb

Private Function Flop() 'First three common cards to be displayed.

I looked around online and I don't think a list will work for my 2-dimensional array.

I am working on a little Hardware interface project based on the Velleman k8055 board.The example code comes in VB.Net and I'm rewriting this into C#, mostly to have a chance to step through the code and make sense of it all.
One thing has me baffled though:At one stage they read all digital inputs and then set a checkbox based on the answer to the read digital inputs (which come back in an Integer) and then they AND this with a number:[code..]
I have not done Digital systems in a while and I understand what they are trying to do but what effect would it have to AND two numbers? Doesn't everything above 0 equate to true?How would you translate this to C#?

I am converting some C# code to VB, the following code is part of a function
if (bool.Parse(v["Parent"].ToString()))
{
e.Row.CssClass = "Parent";
[Code]....
The code throws an error "String was not recognized as a valid Boolean" But if I use this code
If CBool(v("Parent").ToString) = True Then
e.Row.CssClass = "Parent"
End If
It works fine, which is great
