Method Of Object Failed Error While Opening Any Vbp File In VB 6.0?
Nov 10, 2010Whenever I open any VBP file in Visual Basic 6.0, I get Method '~' of object '~' failed error. After that project compiles without any error i.e I can create either EXE or DLL without any error. Originally, all files are Visual Basic 5.0 vbp files and we are converting Visual Basic 5.0 to Visual Basic 6.0. We will be converting to .Net after converting to VB6. Application uses microsoft access as data storage.I am running Windows XP on my machine. I have got .Net 3.5, Jet 3.5 Sp3, Microsoft Office 2003 installed on my machine.
View 8 RepliesIf <expression> Then <statement [:statement]> Else [statements] In Concrete Form?
Jan 1, 2010I was convinced that If <expression> Then <statement [:statement]> Else [statements] in concrete form of If a = b Then SayHello() Else SayBye() End has sense. I read article on msdn on If-then-else, but I forgot why I was reading, so I concluded, that snippet above means this
If a = b Then HelloIsSaid : IsNotEnded Else ByeIsSaid : IsEnded But I have tested it now, and I see, that Else without statement is nothing more than decoration. It would be pretty good if it had function I described. Do you think its good request? Or do you know any circumstance where this Else has some function?
Error: Statement Cannot Appear Within A Method Body. End Of Method Assumed
Jul 13, 2011Why does my the declaration of my string in the code result in the following error? Is there a workaround?
Code:
<script runat="server">
Protected Sub form1_Load(sender As Object, e As System.EventArgs)
Dim x As String = "</script>"
[code]....
Error: Statement cannot appear within a method body. End of method assumed.
Note: The following page did not fix my issue and instead resulted in the string </script> being output in my page. ( VB.NET hates </script> tag in string literal )

Break Up The Code In A Method Body Into Statement By Statement Symbols/"tokens"?
Apr 22, 2011I'm writing something that will examine a function and rewrite that function in another language so basically if inside my function F1, i have this line of code var x=a.b(1) how do i break up the function body into symbols or "tokens"?I've searched around and thought that stuff in System.Reflection.MethodInfo.GetMethodBody would do the trick however that class doesn't seem to be able to have the capabilities to do what i want..dit 2:basically what I'm trying to do is to write a program in c#/vb and when i hit F5 a serializer function will (use reflection and) take the entire program (all the classes in that program) and serialize it into a single javascript file. of course javascript doesn't have the .net library so basically the C#/VB program will limit its use of classes to the .js library (which is a library written in c#/vb emulating the framework of javascript objects)

Dll Error: Expression Is Not A Method?
Mar 4, 2010Ok 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.
Error - Expression Is Not A Method
Aug 7, 2009im 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?

LINQ Statement Where Result Count Is Used In Expression's Condition?
Mar 23, 2009I have a requirement where I have to add items into a List(Of T) (let's call it Target) from an IEnumerable(Of T) (let's call it Source) using Target.AddRange() in VB.NET.
Target.AddRange(Source.TakeWhie(Function(X, Index) ?))
The ? part is a tricky condition that is something like: As long as the as yet unenumerated count is not equal to what is needed to fill the list to the minimum required then randomly decide if the current item should be taken, otherwise take the item.Somethig like...
Source.Count() - Index = _minimum_required - _curr_count_of_items_taken _
OrElse GetRandomNumberBetween1And100() <= _probability_this_item_is_taken
' _minimum_required and _probability_this_item_is_taken are constants
The confounding part is that _curr_count_of_items_taken needs to be incremented each time the TakeWhile statement is satisfied. How would I go about doing that? I'm also open to a solution that uses any other LINQ methods (Aggregate, Where, etc.) instead of TakeWhile.If all else fails then I will go back to using a good old for-loop =)

Any Method Of Showing Data Attractively (No DataGridView)
Apr 9, 2011I'm looking to display some data taken from an Access database. It's just a table of data but all of Visual Basic DataGrid stuff seems too...bland and businessy. I want something that looks really attractive and would be suitable for a game (a sports management one). I'm using some Krypton Controls and even though there is a DataGridView in there, again it's not what I'm looking for. I could just have a listbox for each column of data and that would allow me to customize the style completely, but it would be a bit fiddly working out sorting and stuff (even though I reckon I could do).
View 2 RepliesCannot Evaluate Expression Because Code Of Current Method Is Optimized
Oct 15, 2008In debug mode I get into a line that evaluates to false because the expression cannot be evaluated because of "Cannot evaluate expression because the code of the current method is optimized." Program does not assert or error out. If Item.Length then . . . (Here when I hover the mouse it displays "Cannot evaluate expression because the code of the current method is optimized"). What interesting is that it only occurs in one of .vb files.BTW, I'm programming in Compact Framework.

Way To Stop C# Metadata From Showing When Navigating To Class Or Method
Jan 13, 2012I have a VB.NET project and a C# project in the same VS2010 solution. The VB.NET project is referenced (and used) by the C# project as a project reference. If while I am in the C# project, and I Ctrl-Click or Go to Definition on an element that is part of the VB project, it takes me to C# generated metadata instead of the actual VB code file.Is there any way to get this to go to the VB code file, so I dont have to navigate manually in solution explorer/navigator?
View 2 Replies.net - C# - Code Contracts - Detected Expression Statement Evaluated For Potential Side-effect?
Jan 20, 2012I have a class with a static list of keys, and I have a static method called Remove() that removes a key from that list.Now what I understand from the contracts post conditions is that as the programmer of the class, I guarantee that the current public method does something specific, in this case : removing the element of the list.
Here's what I've written:
private static List<Keys> m_usedKeys; // private list of keys
public static void Remove(Keys _key)
{
[code]....
What I'm trying to "Ensure" here, is that the Remove() method removes the key for real from the list (Yes this might be a trivial example, but I get the error there.)when I write the Contract.Ensures() line, VS2010 gives me the following error :
Error 3 Detected expression statement evaluated for potential side-effect in contracts of method 'LibJungleTimer.KeyBind.Remove(System.Windows.Forms.Keys)'. (Did you mean to put the expression into a Requires, Ensures, or Invariant call?) C:UsersJoelDocumentsProgrammationJTJungleTimerLibJungleTimerKeyBind.cs 51
I think this error says that the expression m_usedKeys.remove(_key); has a potential side-effect. In fact, it has a side-effect, it removes a key from the list!If I try to write something like this instead :
Contract.Assert(!m_usedKeys.Any(x => x == _key));
well it compiles fine.
Xml - C# Class Library Method Summaries Not Showing In Intellisense Of .net Project?

However the "if" statement shows an error " statement cannot appear outside of a method body" and the Microsoft solution is to "move statement into a procedure or subroutine"
