Find Variable Characters In String?
Apr 9, 2010How can I find variables in a string of text and display them.
For instance usually I could use the * or ? characters (in ol' batch files) to mark variable character positions.
For example, I am looking for a string "Happy" & ???? & "Birthday" in a file looking for 4 characters between happy and birthday. Is there a simple way to find these characters utilizing a variable or is there a different way to do it? Would I have to declare?? as 4 specific character spaces that need to be displayed?

Can't Find The .net Equivalent Of A Variable Type Of A "raw" Generic List That Takes A Wild Card?
May 17, 2012I'm strictly looking for a language conversion here of this:List<?> I already have a work around I'm just surprised that I can't find the vb.net equivalent of a variable type of a "raw" generic list that takes a wild card.Java's mechanism here enables you to reference a list regardless of what T is.Java even enables you to go further and do things like:
List<? extends Number>
List<? super Double>I tried:
List(Of )
and that did not work. That only seems to work inside the GetType function.
VS 2008 Error: Range Variable 'sender' Hides A Variable In An Enclosing Block Or A Range Variable Previously Defined In The Query Expression

Program Function - Says, "The Type For Variable [variable] Will Not Be Inferred Because It Is Bound To A Field
May 18, 2012Public Class Form1
Dim x, c, number(0 To 19) As Integer
Dim s As Integer
[CODE]...
The variables in the brackets [example] do not actually have brackets in them in the original code. These are where the issues are. For both variables, it says, "The type for variable [variable] will not be inferred because it is bound to a field in an enclosing scope. Either change the name of [variable], or use the fully qualified name (for example, 'Me.[variable]' or 'MyBase.[variable]')." Now, I'm not entirely sure if this is a stupid question or not, as I'm used to VB '98 because that's what we use in my programming class at High School. let me know why this won't work.
-Note: The intention of this program is to continually loop the generation of numbers for this list until I tell it to stop. Button1 ends the program, Button2 generates the list one time only, Button3 is supposed to loop the generation of the list, and Button4 is supposed to end the loop, but not the program.
VS 2010 Compiler Creates New Variable Automatically When Use If Statement Without Strictly Declared Variable?
Jan 10, 2011Say that i have the following code that parse about 20k records from the DB.
Code #1
vb.net While reader.Read()
list.Add(If(Integer.TryParse(reader(0).ToString, 0), Integer.Parse(reader(0).ToString), 0))
End While
And then another code which does the very same thing but it seems to be a little cleaner.
Code #2
vb.net While reader.Read()
Dim storeowner As Integer = 0
Integer.TryParse(reader(0).ToString, storeowner)
list.Add(storeowner)
End While
This is what i am confused about; does the compiler creates a new variable automatically when i use the if statement without strictly declared variable? What approach is better in sense of performance?
Variable Naming Conventions To Illustrate Variable Type And Where Variables Are Declared
Aug 24, 2009I am looking for a good resource on variable naming conventions to illustrate variable type and where variables are declared. So I will have public variables, Private variables, private or local variables. I also may want to declare variables with the same name in different class code (i.e. in the code behind different forms). I am assuming good coding would dicatate a prefix for declaration location.
View 4 RepliesUsing Selection.Find In Microsoft.Office.Interop.Word To Find Tracked Changes In A Document?
Apr 15, 2009I am currently using the code below within a VB.Net application to find specific text in a Word document. The text is surrounded by symbols represented by the character codes in the .Text statement. The code below is working fine. The issue now is that sometimes the desired text within a document has been marked for deletion and appears as tracked change within the document. I would like to find only the desired text that has NOT been marked for deletion. Does anyone know of a way to determine if the found text is a deletion?

Object Variable Or With Block Variable Not Set - From Property Get With Bindingsource.current?
May 31, 2012Now I have the need to get a current value from a bindingsource in a property of a user control.In a previous thread I had tracked down the "Object variable or With block variable not set" to the return in the Get block of a property. At the time I was only using the Set so I just commented out the offending code until I needed it.
[Code]...
The error does not occur during a system compile, only upon saving the container object of the user control. As I said the Set works correctly, only the Get causes the error.I would like to know what I am missing/misunderstanding and am open to other suggestions of handling retrieving the current value of a bindingsource in a user control.

VS 2008 Does FIND Always Find Within The FILTER Of A Binding Source
Jun 8, 2009I've got a form - CMCConsole It pops up a dialog form for adding a new case.If the matter number in a textbox on that dialog form matches an existing cases matter number I would like to find it in the binding source of the CMCConsole form
Private Function CheckMatter(ByVal MtrNum As String) As Boolean
Dim cfIndex As Integer = CMCConsole.caseBS.Find("MatterNumber", MtrNum)
Dim cfIndex2 As Integer = CMCConsole.casefileBS.Find("MatterNumber", MtrNum)
[code]....
But it appear the filter for the CASE we were just on that is set on the binding source is keeping the FIND from seeing other cases.
caseBS.Filter = "CaseId=" & e.Node.Tag.ToString
Do I have to clear the filter in order to find a matter number in some other case??
