Calling A Function / Assign Property Of An Object Inside An Array
Oct 5, 2010So if I create an object test, and it has a property color. When I add this object to an array list I typically can access this using myarray(0).color but intellisense doesn't 'know' that I have a 'test' object inside the array. It would let me type myarray(0).whatever but would then crash if I made typo. It seems like I should be able to let it know what type of object I am trying to work with inside the arraylist. In code maybe something like this

In .net, If A Function Returns An Object, Is It Wrong To Just Use The Function, _as_ An Object
Apr 30, 2009I've got a f(x) that returns a collection of user controls. .Net lets me just treat the f(x) name as the collection.
ex)
Private Function GetCcB() As Collection(Of Reports_ucColumn)

cc.Add(Me.ucColumn0)

Call A Function From Inside Another And Suspend It Until The Called Function Is Finished
Jan 25, 2010How can I call a function from inside another function and suspend the calling function until the called function is finished? I hope I can get some replies because I don't know how to ask the question and make sense:).
Anyway what I am trying to do in steps:
1. The user clicks button1 which triggers the click event.
2. From the click event I call a function
3. I then pop-up a form, that has instructions for the user to read.
4. After the user has read the form he will click the "Done" button and return to the calling function.
The problem is the the calling function continues to execute. I want to stop execution of the calling function until the users clicks the "Done" button on the instruction pop=up. I know I can use a msgbox but the instructions can be lengthly and does not look good in a msgbox.
I have tried the Call method with return in the "Done" button click but I can make that work. I also tried a goto statement but I can get that to work either. In the call statement I said call frmInstruction.show() and it got there but as I said the calling function continued to execute.
Wpf - Get The Object That Called (executed) .net Subroutine Inside Object?
May 27, 2010I'm trying to extend my new WPF Touch Screen Keyboard (DLL) Library, to allow the user to get events from the Touch Screen Object. I'd like to be able to tell the Programmer what Object made the call (or executed the subroutine) that raised the event. Not dissimilar to the Sender as Object event parameters one gets when working with a System Object. Which begs the question, How do I get that information, if I don't ask for it?Is there a way to get this information from some call made in the subroutine about to raise the event?

XML Serialization Of Object With Other Object Inside .net

View 5 RepliesNew Line Inside ToString Function
Sep 8, 2010VB.NET 2008. How could I make a new line inside the ToString() Function that VB already have. How to do like a .WriteLine() but inside the ToString() function. In my case, this inside of a class of course. I don't know if you get me. All I want to do is to show a fraction in the normal way not using the slash(/). Showing the numerator on top of a line, and below it the denominator. This inside the VB pre-made ToString() function.
This is what I've tried;
Public Overrides Function ToString() As String
Return Me.numerator & "/" & Me.denominator
End Function
Output example: 2/3
But this is not what I want.

Altering Label Properties Inside Of A Function?
Oct 19, 2011I'm trying to validate a form to be filled out by the users, and when the required section isn't filled, I increment an
ErrorCount += 1
variable to show that error(s) have occurred inside the program, I then also set an
ErrorArray()
to whatever the corresponding field number is, now I have 0-12 (13 fields). What I have also done is titled the labels that are associated with all of these fields to correspond with the ErrorArray() value that might be set, such as.
PatLabel0
PatLabel1 etc.
What I am trying to do is loop through the array contents, depending on which ErrorArray() values have been set, to go and set the corresponding fontcolor property of that label to red, to show that these now need to be filled out. This is what I have, but Visual Studio doesn't allow me to use the iteration through the loop as a reference to changing properties. Can anyone point me in the right direction to trying to figure this out, or at least tell me what else I could do. Just seems doing 20 if....then....else.... statements with 2 - 3 lines in each of them is redundant when 1 function line could do the same job. This is what I have.
for i = 0 to UBound(ErrorArray(12))
if(ErrorArray(i) = "*")then
PatLabel(i).forecolor = color.red
[code]....
that is basically all im looking for initially, but I can't do it.
Auto-updating Changes For Params Inside Function Possible?
Feb 24, 2012I am currently facing an heavy struggle with architecturing my VB.Net app.To simplify, i'm using entries from XAML comboboxs, which all trigger OnChange the same routine which manages which Function(s) to use depending on which combobox triggered.The problem i'm facing is for example i have Function(ByVal A As String, ByVal B As Integer, ByVal C as Double, etc...), and it works if the routine calls explicitly for this function's result. But then if another combobox makes for example the variable B to change, then i have to add another "If sender= Then" check for this combobox and recall expicitly the function above (since B is one of its parameters)..In the end, my routine is loooooong like 24 checks with at least 4x duplicates of same functions..is there a simple way to make a Function autoexecute when one of its parameters change without having to be called explicitly by another routine ? (Like Excel formulas do when one of its references change)
