No, if the method is static ( shared ), then that is the ONLY way to call it. And if your methods do not have state, then it makes perfect sense to do it this way.

Could you explain 'if your methods do not have state' ?

Hello,
I need to detect if is there any audio comming out on the speakers.

I searched all the web and all I couldn't find what I need (or perhaps I didn't know how to look or what to look for D'Oh! | :doh:

)

Anyway, I need to check if there is any audio playing(media player, web..) anything that comes out from the sound card.

If anyone can help me, it will realy save me.

(I am looking for a solution for 3 days now Sigh | :sigh:

)

Thank you in advance,

Anomis

Well, if you can hear anything, there probably is. If you can't, then there probably isn't. Although one can never be sure. You might have a partially eaten banana in your ear, in which case you almost certainly won't be able to hear anything.

On the other hand, if you put a shell suit to your ear, you should at least be able to hear Romford.

Hope this helps. Smile | :)

I believe, although I am not able to access VS at the moment, so cannot be sure, there is a OnMeasureItem event that you can override to return a size that you prefer. If you look it up on MSDN I think there is a pretty good example.

Translation to VB [modified]

Hi!

I'm working on a project that involves translating C++ to VB.NET (me not really being a C++ person) and am really stuck on how to translate the following C++ to VB:

sum ^= (((UInteger)(name[i]))<<(off&0x1F));

Where "sum" in an unsigned integer, name is something that I'm not familiar with, but is declared like this:

char *name

And "off" is also an unsigned integer. Do any C++ people out there have any ideas?

Thanks!

Here's some notes that I hope might help (it's a long time since I did C++ but I think I remember it.) Smile | :)

char *name - declares a pointer to a char, this is a common way to access a string/array of chars. VB.Net equivalent would be a string. So name[i] is the ith char in the string.
(I'm assuming that name is a parameter or that somewhere it has been set to a valid string)

off & 0x1F - is a bitwise and of the variable off and the hex value 0x1F (31 in decimal). Effectively this gives off mod 31 (i.e. remainder after division by 31)

<< - does a left shift by whatever that mod gives. Effectively this multiplies the value in name[i] by 2 to the power of off mod 31.

sum ^= - means that the value in sum is Xor'd with the the result of the modding and shifting.

Now how you translate that into VB is another matter. Big Grin | :-D

One thing to be wary of is that the C++ is probably dealing with 8-bit chars in VB they are probably 16 bit. You need to know where the data that fills the name string is coming from and so how many bits per char.

Hi!

Thanks! I was going wrong with the "off & 0X1F" part, I had them all joined together and it gave me an error. It didn't occur to me to separate them out.

All the other information was very useful too, and has helped me in my project.

Thanks Again!

Just a caveat to riced's excellent answer:

Do make sure off is not 0FF (zero F F) written in lower case.

This has nothing to do with programming, if the error is that you need to configure the permissions on your machine. Nor is it something that you can do in your code, to benefit an end user. I get the impression that you're more than a little lost. How are you sending emails ?

But obviously not serious enough for you to google sidebar visual basic, so just how serious can it be?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
