i have a very simple problem but i can't figure how to fix it.I'll explain, i have 3 array named "Auto, Legumes, Films". I i making a function so whenever the selecteditem of the combobox change(Auto, Legumes or Films) the name of the selecteditem is passed to a function. The function use this name to display the items of the corresponding table in a listbox.The 3 different item name in the combobox match the name of the 3 tables, so i want to be able to re-use the name dynamically in my function.
Code where i call the function:
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cbchoix.SelectedIndexChanged
The case is that I have two comboboxes (country and state) and a simple code to populate the state combobox accordingly depending on the selected country. Ok this is simple and easy, and this code is within the country combo change event.The case is that I have more than one pairs of those comboboxes and I wouldnt like to repeat all the populate code into every country combo change event.Actually I would like to have only one function and just call it passing as parameter a reference to the combobox I want to populate. Then I could use that reference into the function.

Basically the application I'm creating has a login screen with two textboxes and one ComboBox... Once the user enters their first and last time for the first time it'll be stored in the combobox's index..Now my issue is this... Originally before I implemented the combobox the related user file name would be:"C:FicheStatsJohn SmithJanuary" + Ttbox1.text + Textbox2.text + ".txt"So basically the user filename would be JohnSmith.textBut now I want the user to directly select from the combobox and that the file name remains the same without space.... but in the combobox the name appears as John Smith.>

I have one problem solved, properly converting text to numbers. Now I want to use that conversion as a selection parameter in a FillBy statement.I have two comboboxes linked to an Access 2007 database. One box lists the names of the States in the US. This is what I used for the Table Adapter Configuration Wizard for the combobox "State". [code] ST_UID is an Integer. I created a label with a bound value to STATE.ST_UID so that when a user selects the name of a state from the State box the appropriate ST_UID populates the label, (i.e, California has an ST_UID = 5). The problem is when a state is selected, I only want the Counties for that state to appear in the County box, i.e, COUNTY.ST_UID = 5 if California is the selected state. [code] Problem is I'm not getting any results, the "County" combobox is blank. I've tried a lot of variations on the code, such as % StUID %, etc., but no luck. I have experience with VB 6 but am a beginner with .NET.
pass an array to a function, like the code below shows
Private Sub SomeFunction(ByVal PassedArray() As String) For i As Integer = 0 To PassedArray.Count - 1 Debug.WriteLine(PassedArray(i))
[code]....
But is there a way to pass a constant array to a function in VB .Net, for instance in PHP you could write
function SomeFunction($array) { for($i=0;$i<count($array);$i++) {
[code]....
So to reiterate: Is there any way to pass a constant array directly to a function in VB .Net? Is there any benefit in doing so? I imagine a few bytes of memory could be spared.
PS.SomeFunction({"some", "array", "member"}) ' this obviously gives a syntax error
It looks like passing a list's enumerator to a function "byval" is quite different than passing it "byref". Essentially, regular "byval" passing will NOT change the caller's "enumerator.Current value", even if the function advances the enumerator. I was wondering if anyone knows why this is the case? Is an enumerator a primitive like an integer, without an object reference, and hence changes to it don't get reflected in the caller?This function is byval, and gets stuck in an infinite loop, spitting out "1" message boxes, because the enumerator's "current" never advances past 5.[code]The difference between the two functions is only whether the listFirstItem__ function accepts a byval or a byref enumerator.
