Replace Static "If...then..else With Dynamic?
Feb 2, 2010
In my work i work with a custom program.This program has hundreds of conditional statements in code " if ...X="A" and Y = "B" or Z = "C" and W = 1000 then S = 1 else S =3 ,F = 2 end if".Any time we want to make a change we have to hunt down all these conditional statements and change them accordingly.I was thinking of separating them from the code,storing them away and preferably testing them and i believe i have an idea about the syntax of how to put them in SQL tables but..the real probelm is how to "parse", "evaluate","run" pick a choice.I just want to get rid of them from the code so when someone comes and add a parameter this won't require me to hunt it down.I am "dreaming" of somekind of console where i could feed the parameters and get back the value i need.So is there any parser that can handle this kind of "dynamic" conditional statements.?
Function CalculateMaximumWeight
if x = 100 and y =50 and h = 200 then
.....if material = "wood" the maximumweight*1.15

Can we execute any string like "Button1.Text = Value"
Question arises from sql server where we can store a dynamic/static query in a string (varchar) and execute it and it will put the value to the button1.

I've got a DetailsView which has some static fields defined in my markup and adds some extra fields dynamically in the VB codebehind. It should be noted that the DetailsView lives in an UpdatePanel.Assume that I would like to get inventory information for a number of warehouses, but I only want to see those which have stock on hand. In addition I have some static information such as product, sku, etc.
The problem I was having was that every time I clicked the "Details" button it would just keep appending the dynamic fields to the end and never re-rendering the table. I figure I either need a conditional or to tell it to re-render somehow. I suspect this problem arises from my use of the UpdatePanel but it's important for the user experience of my customer to keep this.
'Warehouse Stock by Location
Dim stockDT As New DataTable
For Each row As DataRow In stockDT.Rows 'Add column for each Warehouse that has stock

The file reads in parameters and two of the parameters used to be in Date Format YYYYMMDD but will now permanently be in format YYYY-MM-DD. This change, I believe, is stopping the import of the file from working. I would like to replace the new format YYYY-MM-DD back to YYYYMMDD in the code. If possible I'd also like to see some output so I know that the old format has been replaced with the new format. The code is below. I added the two rows with .replace code in green in expecting that to be enough but it is still not working.

Sub Main()
Dim R1, O1, P1, C1, strDateFrom, strDateTo, strRunDate

Here's how I want to the information:If a positive number my Label will be: lblTimespan.txt will show as "12 Hours And 15 Minutes" This works fine.If its a negative number I want to display it as "(12 Hours And 15 Minutes)'[ in red. The problem is that I can't get rid of the minus sign. [code] Thr Replace doesn't seem to want to replace the "-", can anyone suggest what to do?

I have a bunch of object variables which are all initialised in their declarations such that:
Private _myObject As New ThisObject("SomeString")
where ThisObject is one of a number of object types, but all are initialised using a string.
I would like to use the Visual Studio Find/Replace dialog box to search for "As New" then replace everything from "As New" to the first set of speech marks with some text such that:
EDIT
My original example could be solved using other methods. This example is more representative of the actual problem:
Private _myObjectA As New ThisObjectA("SomeString")
Private _myObjectLongName As New ThisObjectLongName("SomeString")

I am trying to think of a regex replace to replace double quotes with nothing. Example:
hello("hi there") would become hello(hi there)
"hi" would become hi
"example "3" would become example "3
-edit Maybe an easier way to explain this is, replace all " that do not have a backslash before them.

I am trying to filter out all unwanted characters from a string. All I want in the string is letters A-Z, numbers 0-9 as well as comma (,) plus (+) and quotes (").I figured how to do the letters and numbers, but the 3 special characters are giving me a problem. I also tried with the Chr(34) equivelant for the " sign, but no luck, as and " or , messes up the way the code is read. Here�s what I have so far, but it only works for A-Z and 0-9:
STR = System.Text.RegularExpressions.Regex.Replace(STR, "[^A-Z, 0-9, Chr(43) ]", "")

I need to represent the following query using LINQ:
DECLARE @PurchasedInventoryItemID Int = 2
DECLARE @PurchasedInventorySectionID Int = 0
DECLARE @PurchasedInventoryItem_PurchasingCategoryID Int = 3
DECLARE @PurchasedInventorySection_PurchasingCategoryID Int = 0
[code]....
Now, I know that a query in .NET doesnt look like this, this is my test in the SQL Design Studio. Naturally VB.NET variables will be used in place of the SQL local variables.My problem is this: All of the conditions after "WHERE" are optional. In that a query might be made that uses one, some, all, or none of the conditions. V.PropertyID and V.Value can also appear any number of times.In VB.NET I can make this query easy enough by simply concatenating strings, and using a loop to append the "V.PropertyID/V.Value" conditions.I can also make a Stored Procedure in MS SQL, which is easy enough.However, I want to accomplish this using LINQ.

Ive managed to dynamically create a form, and dynamically create a timer, but i have not been able to create the timer on the dynamic form. Specifically, i need to be able to have the timer itself create another form with a timer. (I realize that this would create a new form every interval on the timer, that is what i want to do)
1. A way to add the timer to the dynamic form, and maintain the timer sub on my main form.
2. A way to create the whole thing over (dynamic form and timer) through the previous dynamic form and timer.
I was thinking i could use a collection/array to store the forms and timers, but i'm still having trouble figuring out how to add entire forms or timers into a list. (A timer is not considered a control, so i cant use a controlcollection...)
Heres my code;
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim frm As New Form
[Code]....
*EDIT* Btw, my idea was to use i as a variable that increases every time a form is created, then insert the form into the array, with i as the integer. i just need to know how to create a new form with a different name each time. (as with timers)

I have a form that i need to be 100% Dynamic. So it could contain 10 labels maybe 100 who knows.
When you hover over a label there will be a different contextmenustrip to appear for each and every label. So all the contextmenustrips are Dynamic and contain 1 option maybe 2 options even 3 or 4 up to the users settings.
My problem is not creating a handler for when the user clicks on the contextmenustrips options. The problem is knowing which one of the options for that contextmenu was clicked!!

OK, I'm trying to display tooltip text for a dynamic edit box. Well, at least I'm trying to.
On my form, I've got a tool tip control which I've conveniently named ToolTip. My edit box displays OK. But, what I want to do is when the user hovers their mouse over the text box, I want the tool tip to display some text.
I think there are two problems that I'm having. I'm not convinced that I'm properly addressing a dynamic text box name. Ideally, I would want to be able to refer to the text box (but using a dynamic variable that will contain the prefix of the name). To hardcode, I would want to be able to achieve (not in this example but in theory): ABCDEFGt_0300.Text = "hello"
Dim controllerName as string = "ABCDEFG"
Dim t_0300 As New TextBox()
Me.Controls.Add(t_0300)

I am rewriting a C# class in VB. The C# class has a static constructor in it:
static Class()
{
...
}
which, through the Call Stack, I found is called by the main window's InitializeComponent() method.Everywhere I've looked has told me that the corresponding static constructor in VB is just:Shared Sub New()
but this method is never invoked. Am I creating my VB static constructor right? Is it likely something else that has nothing to do with my static constructor?

This will probably be a basic questions for the LINQ & architecture experts however I am failing to understand a problem i've encounted when trying to update a 'Static ObservableCollection.
Me.Grid1.ItemsSource = ContactList Me.Grid2.ItemsSource = From s In ContactList Where s.ContactTypes.Any(Function(t) t.ContactTypeName = "Christmas List")
If I add a new Contact with the ContactType "Christmas List" to the ContactList ObservableCollection, Grid1 reflects the additional Contact however Grid2 does not reflect the change unless I rebind.
Anyway to Reflect the change in Grid2 to show the new Contact with the queried ContactType

We have a DateTime Service that pulls the Database date down when we need to use a Date. Now, If I want to run a test using "Todays" Date using FitNesse, What would be the easiest way of creating a way to have (OurService).CurrentDate be static? We have a control that ads Days,Years, or Months to the current date.. and I would like to be able to test this.
