Hi,
I am trying to create a function that when called takes a pictureBox and make it larger in 5 steps. My problem is that when I run the function the pictureBox is not updated until the last step where the pictureBox is full size.
The picture box is called myPictureBox and has a size of 70,100 at the beginning.
private void button1_Click(object sender, EventArgs e)
{
for (int j = 0; j < 5; j++)
{
zoomOutPicture((j + 1) * 10);
System.Threading.Thread.Sleep(1000);
}
}
private void zoomOutPicture(int zoomF)
{
int myHeight = 100+zoomF;
int myWith = 70 + (int)Math.Round(zoomF * .7, 0);
System.Drawing.Size test;
test = new System.Drawing.Size(myWith, myHeight);
myPictureBox.Size = test;
}
I have spent the last 3 hours searching with out any luck so any help is greatly apriciated.
Thank you.

Hi,
I tried your code on my machine .Net 2.0 vs2005 and it seems to work fine. I added a line that refreshes the form so maybe try this and see if the results are any different.
private void button1_Click(object sender, EventArgs e)
{
for (int j = 0; j < 5; j++)
{
zoomOutPicture((j + 1) * 10);
this.Refresh();
System.Threading.Thread.Sleep(1000);
}
}

Hi Dave,
Thanks a lot, that did the trick.

Try:
myPictureBox.Size = test;
myPictureBox.Refresh();
My failometer has shot off the end of the scale!
I seem to have misplaced my ban button.. no wait... found it!

you could "solve" it with some Invalidate() or Refresh() calls, but your approach is fundamentally flawed, since you are blocking the GUI thread for the entire duration of this action, making moving, resizing, e.a. impossible.
The correct approach is by using either a separate thread or a timer; since the actions involve Controls, which need to be handled on the main thread anyway, your best option is to start a Windows.Forms.Timer

Hi Luc,
I tried the Invalidate() with out luck but the Refresh() is working.
I will look into the timer when I get a bit more time bur for now Refresh() does the trick.
Thank you.

I don't know of a way to make an arrow key into a hot key, other than overriding one of the key events. There may be a way, I just don't know.
As far as why the underline appears or not, in the later versions the underline on menus, buttons, etc. only appears after one presses the Alt key. For better or worse, that's the way the system works. (Personally I liked the underline always showing up, but it's not a big deal.)

Isn't that configurable in Windows?
Display properties | Appearance | Effects | Hide underline blah blah blah
I always clear the checkbox.
[Edit] This is for Win XP, and perhaps earlier.

Thanks PIEBALD, I just learned something.
"If you're using Windows Vista, go to the Vista Control Panel - Appearance & Personalization - Ease of Access Center - Make the Keyboard Easier to Use. Check the box by "Underline keyboard Shortcuts & access keys". "

Thank in advance

Since you don't say how you are retreiving web pages, it's pretty much impossible to tell you how to do this.
|
|
|
|
|
Couldn't you just add something to a "global" variable every time something is downloaded/uploaded?

is slightly different from "I am bulding a webbrowser"
You could try and use the WebBrowser.Navigating event to perform a little WebClient or HttpRequest action getting the size of the page (just ask for the HEAD, it should contain length information) before the WebBrowser loads it.
Alternatively you could hook up the DocumentCompleted event and hope to get the length from the DocumentText property, but I am not sure that would always be correct, and if so, efficient.
For uploads, I don't know.

Maybe "I did/didnot create a browser" didn't go down well.

That's just IE embedded in a control. I have no idea how to steal such statistics from it - if IE even has them then it has* to be possible somehow but maybe you'd need nasty hacks.
* yes it would have to be possible, if the information is somewhere in RAM and someone (IE in this case) knows where it is, then you can get it

As far as downloading html, you can access the browser control's DocumentText and get the size there. If you're downloading files, graphics, etc., I think you'll need to handle and count those sizes manually.
As for uploading, well, since you'll be controlling what to upload, just get the size when you upload it.
Or did I miss something?

What if you use an upload thing that is present on some sites? IE would upload the file then right?
|

Probably so. But if IE is handling things directly, then there's no real way that I know of to figure the sizes. As you pointed out earlier, IE might have the statistics -- if there's a way to get to them.
I don't know a general way to do what he wants. I'll be interested in seeing if someone else has a solution, though.

Since you're not actually building a brwoser control, but wrapping the one in the toolbox in your own UI, there's no real method to get the data you want. The browser doesn't expose this information and using alternate methods would only result in partial results at best.
If you want those stats, you're going to have to build and make the requests yourself and handle the returned page as well. That's about the only method you've got to knowing how much data was sent and received.
