OK. That wasn't evident from your post.

You may want to encapsulate the check for elapsed time in a class (eg: ElapsedTimeChecker) that has (a) a static member lastTimeCommandWasUsed (static preserves its value across calls) and (b) a public static method CheckIfXMinutesElapsed() as shown earlier. Then just call that method when you're about to perform the code you want to execute every 3 minutes, by doing this:
if (ElapsedTimeChecker.CheckIfXMinutesHaveElapsed (3))
doSomething();
else
sorryYouMustWaitAtLeastThreeMinutes();

Nah, I know. I just needed to think twice.
Let's leave that for now.
I will try your suggestion in a little while.
Anyways, thanks.

I've done that, and it works perfectly now. Thanks a lot.
I didn't expect this to be so "advanced" 
Anyways, thanks again.

Could anyone please post some code for a simple sound to play that everyone has using DirectSound? (When adding reference, please tell me which version if you decide to do this.) Thanks.

Have you installed the latest DirectX SDK? If so you'll find an application called DirectX Sample Browser which has a PlaySound sample application you can install and play with.

I went through it, and it was a sound application, but in the source, all I found was Direct3D things, honestly. Should I feel like an idiot? (No smart comments) PLEASE HELP!

Hey.
By spying on windows in IE and IE7 i've managed to retrieve the URL
to my application using FindWindowEx and SendMessage API.
The thing is, now i would like to retrive them from Firefox and Opera browser aswell. When looking at Internet Explorer on a spy tool i can see all the controls, For instance, a TabControl, in that TabControl
there is something called ReBarWindow and in that i can see that there is some ComboBoxes and in those there's an Edit field (Textbox).
And thereby i can grab the handle of that control and do what i please.
In Firefox or Opera for that matter there are only 3 "windows" and all sub-windows have exactly the same name, and there is no way to tell WHAT is What?
So, what i basically need is a handle to the combobox in firefox, which for me atleast seems to be invinsible..?
I need help on this, i hope i explained well.

My timer callback delegate may decide to dispose the timer if certain conditions are true.
Do i need to lock(this) before doing so since another callback may be executed at the same time?
thanks alot !!
more details if you have the time:
when event x happens, i construct and start a timer with the callback function Func. Func checks if there are items in a list:
If there are items it handles the items
else it disposes the timer.
Func will occur in a timely fashion till list will be empty - and timer disposed.
If event x will happen again and the timer already exist - do nothing, if timer doesn't exist - construct it again.

Hi,
if it's a Windows.Forms.Timer its handler runs always on the GUI thread, so it can't reenter.
if it's a Threading.Timer or Timers.Timer it may reenter before it finished an earlier call.
Anyway, if you may need the timer again later on, why dispose and recreate it? a timer
is not that expensive, you could just Stop() it, and later Start() it again.

Hi Luc, thanks for answering me. i use Threading.Timer and i didn't see any Stop \Start methods.
I found only ways to set it to infinte time, thus disabling it. But then when i need to check
whether it's already disabled, the check seems akward - i have to check if it's set on infinte time.
Is there an equivalent of stop and start that i missed?
thanks and have a great day

Hi,
Threading.Timer has Change() method; the other two timer classes do have a Start() and
Stop() method, and an Enabled property, so they might be more appropriate for your purpose.

Hi,
I have currently a problem with my ListBox.
It's the first time I implement a specific draw item function
The problem is that when I clear my ListBox the draw function is still called !!!
I dont understand why, if I clear the list I shouldnt have any items in the list why is the draw function called ?
Thanks for any help !!
|
|
|
|

When the DrawItem event is fired and there are no items in the ListBox, then you really just need to draw the background. The DrawItemEventArgs[^] has an Index property which tells you which item you are drawing. If this value is -1, then you are not drawing an item (probably because there are none). In addition, the State property tells you what you need to draw.
Take care,
Tom

Hi.
Im trying to make an automated gallery browser that can scroll through web pages and download all the images off them. It is currently working, using a webBrowser control. I have a list of all the images on the page in a listbox on the side, each with a thumbnail preview image. However, i am on dial up (laugh and get it out of the way), and the way the application currently works is to download the url to the browser, extract the img tags from the source code, and download each image as a bitmap. This takes ages as it has to download each image twice, once in the web browser and once from the url of the image.
I am wondering if there is anyway to extract the images from the webBrowser control so i dont have to download them twice?
I have played around with the webBrowser.DocumentStream, but cant work out how to get the images.
Any help appreciated.

Just an idea, not sure it will work, not sure you will like it:
tell Internet Explorer to not show images (uncheck Tools/Internet Options/Advanced/Multimedia/
Show Pictures). That way the browser should not follow the IMG tags automatically.
I reckon you'd better forget about the browser control, and do HTTP calls yourself,
using the System.Web namespace.

The browser control is embedded in a form, its not using internet explorer.
Guess i will have to start doing some research into the HTTP Requests.
I knew taking the easy way would catch up with me in the end  
Is there anything good to be said about using the AxSHDocVw.AxWebBrowser, or is it similar to the Windows.Forms.WebBrowser?
|

Did you try what I suggested?
AFAIK WebBrowser uses the settings set in IE.
I expect WebBrowser and AxSHDocVw to be very similar.
