Collate Common Values - Pass A Variable Name Into A Subroutine?

Aug 31, 2011

Pass Parameters To A Subroutine From A WPF Button?

Jul 26, 2010

I have a VB.net WPF application that creates a list from a databind. For each row in the databind, it generates a textblock that displays the information from different fields in the databind. It also generates a button which I would like to run a subroutine when clicked.

When I click the button, I want it to be able to get the information from the databind on the column the button is clicked, and to pass it to the subroutine so the code-behind can use that information.

.net - Find Common Values In Several Arrays Or Lists

Dec 23, 2011

Find common values in multiple arrays with PHP Pretty much does what I need, but in PHP, I need VB. My situation is I am trying to create an intelligent stock pick system based on multiple stock locations. At the point of invoicing, we loop through the items invoiced and check the stock database for available stock.

If all items on the invoice are available to pick from stock location 1, then all should be picked from stock location 1... etc. If all most items are available from stock location 1 except one or two, then pick all stock from stock location 1 except for the exceptions which should be picked from the location with the highest available stock. Finding highest available stock is simple, but I can't work out how to analyse the stock availability from multiple locations and finding the common stock locations.

Forms :: Can't Pass Variable From One Form To Another?

Jun 8, 2011

I have one form, which the user enters upto 5 websites then clicks go - I have on the second form, the one with the webbrowser. A timer which checks if the web browser is busy then either a green light or black image will be shown along side the assocaited input box on the first form.I am finding it impossible to feed variables into the clock through ByVal, like I would a subroutine or function.

Private Sub ActiveMe_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ActiveMe.Tick
If ((WebBrowser1.IsBusy)) Then
Hey.BackColor = Color.Black[code]....

'Error message says Hey is not declared, as i can't pass it through to timer

The variable Hey is determined by the first form - Which picturebox.I have an if statement which simply says if inputbox one has url enter then Hey = Picturebox1, If input box2 has url entered then Hey= Picturebox2 etc.What I want is the timer to check the page has completed loading or is still loading or refresing and the appropriate green or black to be shown aside url input box on first form.I considered using a sub or procedure to act as a clock (a large for loop with another for loop within it, acting as a delay). But found this slowed down theapp to the point of crashing it.

Pass Variable As First Parameter To A NameValueCollection?

When adding to a NameValueCollection you normally would do this:

but if you dont know the first parameter until you read it in from a file then you would want this:

nvc.Add(myVar, "MY VALUE")

this does not work! The NameValueCollection parameters SAY they want a string, but they really don't, they want a "Literal" sting.

So, the question is: How do I pass a variable string to the first parameter?
