actually it would equal zero but god if I was maintaining that could I would be throwing punches I mean really int32.Parse() is very short to right

int binToHex1=(0*2^3)+(1*2^2)+(0*2^1)+(1*2^0);
Howcome that won't evaluate the 5, the right answer... it always comes out to 6!?!

That is because in C# ^ is not the exponentiation operator. It computes the bitwise exclusive-OR of its operands. Try this:
double binToHex=(0*Math.Pow(2,3))+(1*Math.Pow(2,2))+(0*Math.Pow(2,1))+(1*Math.Pow(2,0));
The result will be binToHex=5

I want to display the bitmap of an active form, in a MDI app, in a picture box. The picture box control is on the MDI form, whenever user changes the current active form, the picture box control should show the picture of the active form. I want to know how do I get the picture of the active form.
One method I can think of is:
1. Get the Graphics object of the active form
2. Get the HDC from the graphics object
3. Create a blank bitmap of the same size as the size of the form.
3. Use Win32 function BitBlt and copy the pixel data from the form's hdc to the bitmap's hdc. Save the bitmap to a file and show the file in the picture box.
Is there any other (simpler) way to do this?
Thanks

Use the EnsureVisible() method of the ListView, passing it the index of the item you want to make visible.

Pardon me a C#-novice's question.
Consider an object and one or more references:
CWhatever oObject = new CWhatever("xyz");
CWhatever oReference = oObject;
Changing a property value of oObject will be "seen" from oReference of course (oObject.abc == oReference.abc will be true), however, both will relate to two distinct objects as soon as a new one is created and assigned to oObject:
oObject = new CWhatever("uvw");
Is there any language tool that allows for all references to oObject to be updated accordingly, so that (oObject.abc == oReference.abc will *always* be true, even after re-allocating oObject)? Basically, I do not want oReference to refer to what once was, I want it to refer to whatever is current.
I am aware of techniques that I can implement to solve the problem. I am wondering if there is a language built-in to assist me.
TIA,
Bernd

AFAIK, No there isn't
|

|
|

It seems the most C#-ish solution is to employ MemberwiseCopy() and/or ICloneable, so as to avoid re-assignments to the original oObject. Instead, oObject will be updated, therfore keeping the references in sync.
Any thoughts?
TIA,
Bernd

I want my classes to inherit my felection functions but I have 2 questions
lets say property is defined as
enum myEnum : int
{
a=0,b}
public myEnum propertyA{get... set...}
how in reflections can I cast to the property type of that value
like in SqlServer it is a tinyint field and I need to cast to the enumeration type so the property will accept it
(myEnum)propertyValue;
thanks

Thanks for checking out this post. Here is my issue. I am trying to build a tree view with data stored in a database table. The table is simple, it contains a folder id, name and parent id. The root folders will all have a parent id of zero (0). If a record has a parent id other than 0 then I want to creat that folder as a child folder of the parent linking them on parent id = folder id. In VB6 this was totally possible, because you had to come up with the key that made the folder unique. I haven't been able to find out how this is done in C#, can anyone help point me in the right direction?
