Yes, immediately when you assigned its value to _bVar.

Why are you even doing this, though? No matter what you do, it's going to be a giant hack. It already was in C++, and in C# it's going to be worse.

Why is it a hack? It makes my code more reliable and easy to maintain. If I introduce a new code path with a new return point, I don’t have to remember to do ‘the thing’ every time. You are not limited to toggling a bool, you could call a function, signal a synchronisation object or change the cursor. Microsoft use it in their CWaitCursor class. It’s no hack, its brilliant!

Well maybe. But it's "invisible logic". That something happens even if you forget it may seem nice, but it's the dirtiest possible side effect if } executes code. Combined with threading it would be the recipe for certain disaster. In C# you can't even do it without abusing using, which is meant for disposing things, not for "doing whatever".
As for MS doing it, well they can't rely on programmers doing what they're supposed to do. But if you are the programmer, certainly you can do what you tell yourself to do. You do it all the time, and forgetting to do so is called a bug.
Anyway here's a suggestion: don't have multiple return points. Problem solved.
If you really want multiple return point, you could wrap the whole thing in a try/finally. You won't have to remember "the thing" all the time (just once ... same as when using using), and the side effect is explicit.

So far a C# is concerned I agree, try/finaly is the best aproach.

If you're using Windows Forms, use a WebBrowser control and set its DocumentText[^] property.

WebBrowser : how to show popup window?

Hi,

I am using the WebBrowser control in a winform application. Is there a way where in WebBrowser can show the popup window as a part of navigating to a URL.

Scenario:
- Navigate to a login URL using the WebBrowser control.
- Navigating to this login URL popups a window (in the IE) which shows the session/usage. I need to show this popup in the same WebBrowser control itself and not in IE. Can this be achieved.

A few things - this is an international site, so the people who know the answer may not be online when you post your questions. More importantly, this is a volunteer only site, so badgering for the answer only serves to irritate people. There's a dedicated Silverlight/WPF forum, don't you think this question would have been better asked there (surprise, surprise, the people who could best answer this question tend to hang around on that forum).

Regenerate Designer Code File?

In VS 2010 C#, is it possible to force the IDE to regenerate the designer-generated code file?

I have one that's messed up, and I'm hoping to fix it by regenerating it.

The difficult we do right away...
...the impossible takes slightly longer.

If you have the form designer window open you can sometimes do it by adding, deleting or modifying a control and saving the project. Alternatively you can try (carefully) modifying the designer file outside the IDE and see how much can be recovered. However, if you cannot get the form designer window open and the file is truly messed up I think you will have to start again.

Wouldn't it be nice to have a VS option to auto-backup the Designer.cs file a user-specified number of levels.

multidimensional array index to linear index

Keith Vitali7-Dec-11 11:42

Keith Vitali

7-Dec-11 11:42

Hello all,

I am porting some C# code to C++ and there is a particular bit that has me a bit perplexed. The code is as follows:

byte [,,] data = new byte[d,h,w];
int i=0;

for (int z = 0; z &lt; d; z++)
{
   for (int y = 0; y &lt; h; y++)
   {
     for (int x = 0; x &lt; w; x++)
    {
      data[z,y,x]=bytes[i++];
    }
  }
}

So, the variable "bytes" contains data that I have read from the file. Normally, I would calculate the linear index as follows:

index = (z*h+y)*w+x;

However, this seems to be not be the right thing in this case. I was wondering if someone knows if I am doing something obviously wrong...

Thanks,

Keith

It depends of course on the desired orientation of the array, but how about x + (w * (y + (h * z)))
