Hello everyone,

What is the most convenient way to check whether elapsed time from some time point to another time point is larger than 2 seconds?

Currently, I am using TimeSpan, and I am using stupid method to check hour/minute/second one by one to decide. Are there any quick way to check?

thanks in advance,
George

Just use TotalSeconds:

DateTime start = ???;
DateTime now = ???;

TimeSpan difference = now-start;
if(difference.TotalSeconds > 2)
  more that two seconds longer

Hi,

DateTime check=DateTime.Now.AddSeconds(2);
...
if(DateTime.Now>check) doSomething();

I find it easier to use.

But read the documentation. It has greater precision which may not be important in this case, but maybe down the line you'll find you need it.

Inverted text on image

Kir Birger12-Apr-08 4:30

Is it possible to somehow draw text on an image with an inverted color? I basically want to make a small timestamp that always shows up, and I don't want to resort to putting it in a colored rectangle if I can avoid it.

I've got access to framework 3.5 if that helps.

Im not entirely certain that would be very readable either, with the changing colour and whatnot. What about an outline around the text?

EDIT: But, if you want inverted text, then how about:

ImageOne - original image
ImageTwo - empty image with same dimensions as ImageOne, white background
ImageThree - Duplicate of ImageOne

Step one:
Draw Text to ImageTwo in black

Step two:
Invert the colour of ImageThree

Step three:
Read the colour of each pixel in ImageTwo.
If the colour is WHITE, then set the same pixel in ImageThree to bright pink or something (255,0,255)

Step four:
Set the transparency key of ImageThree to the same colour as before (in this case, [255,0,255])

Step five:
Draw ImageThree on to ImageOne

A question about web browser control.

I have a web browser control in my program, and I'm change its url property to different urls, via a foreach loop.
Now, the problem is, that the "Document Loaded" event only fires for the last url in the list, and the only page you eventually see is the last, what i want is kind of a slide-show effect.
is there any way to force the control to pause the loop and fire the event for each of the urls in my collection?

Instead of using a for loop, why not use a timer with an interval of <insert time you want each page to be displayed here> and change the url on each pass through, you could do something like:

Timer()
{
    static int counter = 0;
    switch(counter) {
        case 0:
            navigate to url
            break;
        case 1:
            navigate to url
            break;
        case 2:
            navigate to url
            break;
        case 3:
            navigate to url
            break;
        default:
            counter = 0;
            myTimer.Stop();
            break;
    }
    counter++;
}

this might work, but if some site takes extremly long to load (or longer than usual) then the slideshow might miss a website, or show it for too long/too little.

what i want is for the browser to sort of pause the thread, untill the website hes showing is loaded completly, is this possible?

Re: A question about web browser control.

Okay then, how about using the DocumentCompleted event:

DocumentCompleted()
{
myTimer.Start();
}

Timer()
{
    static int counter = 0;
    switch(counter) {
        case 0:
            navigate to url

            break;
        case 1:
            navigate to url
            break;
        case 2:
            navigate to url
            break;
        case 3:
            navigate to url
            break;
        default:
            counter = 0;
            break;
    }
    counter++;
    myTimer.Stop();
}

That way, the set amout of time will pass, then the page will change and the timer will stop. Once the page is loaded the timer will start again. After the set amount of time passes again it will navigate to the new page then stop the timer... and so on.

Good Day,

I've been searching for it in Google for like 2 hours but can't hit the proper keyword.

I have a Windows Form with a Listbox on it. When I drag a file from the desktop inside the Windows form, I want to have the path of the file added to the listbox.

Is there an article or a guide on how to accomplish such feat? Laugh | :laugh:

Thanks!

What is AsteriskIAXClientWrapper ? If it's an article, ask the author ? If it's a third party library, ask the vendor. Odds are, none of us know what you're talking about.

But, it looks to me like you have a missing entry in your config file.
