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)

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 =)

View 6 RepliesUsing The Replace Method To Get A Count Of How Many Actual Replacements Were Made?
Aug 5, 20091. In the old VBScript, there was a compareMethod (binary or text, which with text, I could compare case) but I don't find anything like that in the new .Net Replace method. I know I can use the old way, but I'd like to use the new Replace method. I just need a choice of comparing case or not?
2. Let's say I have a long string, and I am using the Replace method - - it would be nice to get the count of instances replaced, and I'm sure that if I read line by line, I could actually get that count, but it would take to long.Is there a way, using the Replace method, to get a count of how many actual replacements were made?

DataGridView Check Record Count - Infinite Loop
Jul 26, 2010As you all know, If the dataBase requires a numerical value then an error will occur when the user tries to insert the incorrect data type. With the code below after the user types in a value beside an int value type then it will go into an Loop through more than what is needed. How can I apply the same logic but allow the program not to check the 60 rows (I set the row size to 60). I want to break out of it if there are blanks ONLY if a row is blank and not for a black cell, because if the user leaves one cell blank then it would loop through the 'for each' for how many rows that they is. Initially there are 60 rows.

For Each item As DataGridViewRow In dgvLaser.Rows
If IsNumeric(item.Cells(3)) Then
Exit For
Else
MessageBox.Show("Check Record Count. Numerical values only..!")

VS 2008 - Loop Count In Label Stops Refreshing
May 28, 2011I am using a label inside my loop to get a count on the number of records processed by the loop. during testing of the program I noticed that if I load a smaller Table( 1000 records) my label stops refreshing after about 110 and my mouse turns to an hour glass. The program finishes and the label returns the correct count when complete If I load a larger table (10,000 records) it works all the way through???

How For Each Loop Statement Actually Works

While Loop Vs If Statement When Printing?
Jul 28, 2010I'm practising printing, and doing fairly well - not as hard as I was thinking.
My question is: is it better/preferable to use a "while..." loop instead of an "If..then" statement when printing.
All my printing code is in various If statements (if PgNbr = 2, If PgNbr = 3 etc) but I notice in most of the examples and webpages I read that a lot of printing is done in a "while..." loop

Is a synclock needed before the if statement or for loop? In other words. When you call methods like .length or .count is it necessary to synclock them or can another thread be writing to it at the same time. CompletedOrders is a generic list of a class.

Basically I am trying to update each record with 2 random numbers each time the button was clicked,my problem now is, the system will update the record but the data was wrong. Example, by right all data should be different (randomly string) but for some row it was updated with same data but in randomly, something row1 row2 row3 has exactly same data for column 1 and 2 then row 3 has distinct data, second time, row1 row2 same data row3 ro4 with different data. It is in random sequence. When I add a MsgBox to do testing in the For loop the data was updated correctly with all different data.
