Call Form With Argument?

Jan 11, 2010

I have a form that loads in my project and does some task on its own, then closes itself. I'm implementing a new functionality into the program where I need to call this form with an argument (to later be used as a conditional clause). If I call the form from a certain button, I want to launch the new form with an argument ("automatedTicket") and I will then use this argument as a conditional test in the code of the form.where, in the ACCEPTING form do I put the argument declaration?

basically i need to do something like:

ServiceTicket.Show(False) 'false for being a manual ticket (click of button)
ServiceTicket.Show(True) 'true for being automated (no user intervention)

then in the ServiceTicket form, where do I put that I'm expecting one argument? and where do I declare that argument name (automatedTicket)?

Passing Argument Into Dll Call?

Mar 7, 2010

In my vb.net code I want to call a dll file created by Qt4.

Now everything works fine untill and unless I pass some string argument to the function.

Here is the function in dll file:

const char* QtEngineDll::randInt(char url[])
{
QString result;
/*QTextCodec *codec = QTextCodec::codecForName("UTF-8");

[Code]....

When the function returns some constant value, say if i put result = "Abhijit" then it returns the value properly. But if I want result to return value url the it is returning some garbage values.

Java - Multiple Argument Constructor Cannot Call Each Other Itself

Mar 29, 2012

I have recently found out that no argument constructor and multiple argument constructor cannnot call each other in turns. What is the underlying reason of this limitation? Some might say that constructors are where resources are initialised. So they must not be called recursively. I want to know if this is the only reason or not. Functions/methods/procedures can be called recursively.

"Procedure Call Or Argument Is Not Valid" Error?

Jan 27, 2012

I have a "working" program for a Vigene cipher, but I am having an issue that I can't pinpoint. Anytime an accent mark is used in the plain text i get a "Procedure call or argument is not valid" error. So trying to encrypt "Vigene cipher" for example will not work. Using the plaintext "f" with the keyword set as "b" the output is Decryption handles these characters just fine. The following code is my encryption sub:

Private Sub btnEncrypt_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEncrypt.Click
Dim Key As String = txtKey.Text 'makes the password

VS 2008 Different Ways To Call Another Form From A Parent Or Preceding Form

Aug 4, 2009

I need to know the proper way, or maybe I should say, the different ways to call another form from a parent or preceding form. I am currently using ex: formname.showdialog() to call my next form, but I am uncertain if I should be using that in every situation. [code] Whats the difference between these different methods? (ex: .showdialog() , .show() )I tried both of these to open a temporary form to retrieve a persons name from a database, so as the users progresses through my training program they can keep track of their scores.But, I also call other forms as I branch through my program, from the main page, to a secondary page, to a testing page, to a results page and then back to the secondary page

Event Argument For The Form Click Event Has The Type "TimedEventArgument"?

Dec 23, 2009

As you noticed, in the code bellow, the event argument for the form click event has the type "TimedEventArgument".When the event is raised, e.Time holds the time where the form was clicked.Add the missing code in the class Form1 to make this work.You will not change anything to the methods "Form1_Click" or "Form1.Load".You will not use Option Strict On. HOWEVER, you will not do any narrowing or late binding that wouldn't have been allowed if Option Strict was on.You cannot create any new Class, Structure or Module.You cannot cast the EventArgs to TimedEventArg in any way
