IIF has always been available to VB. The problem is that it is a function not an operator, which of course makes it nearly worthless. Starting with VS2008/VB9, the If operator was added that can be used to do the same thing as both the ?: and ?? operators depending on the number of arguments you pass.
condition ? truevalue : falsevalue becomes If(condition, truevalue, falsevalue)
condition ?? nullvalue becomes If(condition, nullvalue)

Use CASE statements in SQL to simulate IFF
SELECT Category =
CASE type
WHEN 'popular_comp' THEN 'Popular Computing'
WHEN 'mod_cook' THEN 'Modern Cooking'
WHEN 'business' THEN 'Business'
WHEN 'psychology' THEN 'Psychology'
WHEN 'trad_cook' THEN 'Traditional Cooking'
ELSE 'Not yet categorized'
END,
price AS Price
FROM titles

Hi all!

Hi all. I'm working on a project where users enter scripts in a richTextBox and syntax-highlighting would help. Can anyone recommend a windows forms control or extender that has this functionality? I've googled and found some, but would like a recommendation from someone who has used one and has had a good experience with it.
thanks --

Scintilla.net is a good component for that purpose. In addition it is free.(I am using it in an internal application). The only disadvantage is its learning curve.

My program is simple. Grab an object and move it by using "regions" as drop points. I'm using transparent borderless forms added to ownedforms(), position them on the screen where my objects can be dropped. I've tried 3 appoaches to this task.
1. tried using drag and drop to drop the object onto the forms and it works great unless you release the mouse somewhere other than one of the floating forms, then the program hangs waiting for a "drop" because I can't determine that the mouse button has been released to cancel the move and therefore can't remove the floating forms and continue.
2. tried using control.mouseposition to track screen movement and pointtoclient when appropriate for placement inside of a floating form. This doesn't work because as long as the mouse button is held down the ownedforms() floating above the main form won't see the mouseEnter, mouseMove or mouseLeave events because capture is stuck in the control I started this action on.
3. Tried number 2 with getChildAtPoint() to try and figure out when I'm over the ownedforms() floating over the main form but whether I use
findform for "f" then f.getchildatpoint() or this.getchildatpoint() or any other control call I can only get single items "children" that are actually part of the main form's control collection. Any answers to any of these ideas would be helpfull.

In visual c++ 2008 when you create a windows forms application it creates a file called Form1.h
What type of file is that and how do you write a program around that to use the values that you input them, use them and output the values of an algebra question for example.
I am completely new to windows forms so if you could show an example it would be great.
thanks
ps if there are any good books that tell you how to program with windows forms that would be great

Form1.h represents your Form1 (which is a class Form1 derived from System::Windows::Forms::Form), and contains code related to it. We can declare out objects and controls here.
Just to give you an idea, following is a small code snippet which takes number from two textboxes (which are already on form1) and after adding these numbers, shows sum in a message box. –
-------------------------------------
private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e) {
int i;
i=System::Convert::ToInt32( this->textBox1->Text);
i +=System::Convert::ToInt32( this->textBox1->Text) ;
System::Windows::Forms::MessageBox::Show("Sum : "+i.ToString() );
}
-----------------------------------------
As you want to get books on Visual C++, I would advice you to search on google.

Hello,
I am not very sure about book for learning .Net programming with Visual C++… however using Google I found two links which should be useful for you.
1) Good tutorials on different topics –
http://www.functionx.com/vcnet/index.htm
2) Msdn page (I have not checked any of the tutorials available here so don’t know how they are) –
http://msdn.microsoft.com/hi-in/library/60k1461a(en-us).aspx
I hope this helps.
-Dave.
