Well if you use the IP address of the target machine the network layer will automatically use the adapter that links the machine with that IP address.

Sending a UDP package to the universal broadcast address 255.255.255.255 should work on all network interfaces... at least on Windows. Broadcasting is only guaranteed to work within the LAN, in case you have a bigger (company) LAN the broadcast could be limited to your network segment. UDP is commonly used for service discovery in the LAN, once peers have found each other you can switch to another protocol, because UDP is not the most reliable transport available.

Give it a try! Smile | :)

Thanks for the replies.

When you say it should work on all network interfaces, when i open a socket how do i know which adapter/port it will do it on? Im assuming it wont broadcast it on all ports, or will it?

The issue comes in is this...
The testing machine would be on two networks, the corporate and then this "link" to the other machine under test(neither of which have an IP address assigned on that link).

I absolutely can not be sending broadcast packets across the corporate network, it must go over the other port im just confused looking at the inputs for the Winsock functions how you would specify which port to use if there was no IP address on either end.

In this case use the broadcast address of a specific network segment or interface.
See http://en.wikipedia.org/wiki/Broadcast_address[^] how to calculate one.

How to code a skinned UI like in Windows Media Player?

Hi,

I would like to create something similar to the Windows Media Player miniplayer in the task bar. I don't expect many problems with coding the desk band (plenty of documentation about that), but I'm still wondering how to start with coding the skinned UI.

When looking into Windows Media Player's resources, I have found the following images: http://img130.imageshack.us/img130/5195/wmpbandimages.png[^]

The first image is obviously a mask, and then there are images for normal, disabled, hottracked and pressed states. I guess that I should take the different parts of the 'state' images (according to the state of each part), and merge these into a single image that shows the current UI. But how can I do this?

I would prefer not to use any libraries, just C++ and the plain Windows API.

Thanks.

Thanks for the link, but that tutorial only shows how to create non-rectangular windows with a bitmap background. I don't need a non-rectangular window, but a normal window with non-rectangular buttons on it, by using a colored mask (the top image in http://img130.imageshack.us/img130/5195/wmpbandimages.png[^]).

Sorry, but your title asked for information on "skinned UI". I'm not sure how to do the buttons you are asking for, but probably something similar. Try the articles here on CodeProject, it's quite likely some other CP member has written about it.

Rather than using 3rd party gui library its hard to say its possible. If you can use some library like SkinCrafter then you can easily get what you want.

Of course it must be possible, I'm pretty sure that no library was used in the WMP desk band either. SkinCrafter looks like it's hugely overkill for my (relatively simple) problem.

OK, I've done some more searching, but unfortunately, I couldn't find any examples of how to use such a multi-colored mask.

However, I think that I should take the following approach: for each color in the multi-colored mask, create a 2-color mask with the current color replaced by black, and all other colors replaced by white (by using something like ReplaceColor at How to replace a color in a HBITMAP[^]). Then, those 2-color masks can be used to BitBlt the individual segments (that might come from different state images) into one single image.

Is this the right approach? I want to be sure that I haven't missed anything before starting to implementing this.

I cant understand why you are going towards complicity. Just use SkinCrafter or some other Skining library like DSkin which has Vista, Windows MPlayer skins and lots more. you just need to use their .dll and .cpp and .h in your project and a few lines of coding.

As I already said, I don't want to use a full-blown library for such a small and simple skinned area with just a few buttons. And there's also the matter of personal interest; I would really like to know how it's done. Using a library just because you don't know how to do something, is a wrong reflex.

Does anyone know if the Visual Studio 2010 documentation includes the Visual C++ 2008 Feature Pack documentation sections (specifically the MFC Feature Pack related stuff) or do 2010 users still rely on the online MSDN documentation for the feature pack topics.

Hi, In my MFC application,im invoking one console application,using ShellExecuteEx() and im passing value like "MODEL" to that console application and im receiving this string using argv[] in console application.
Like the same way, i want to receive one string from console applciation to MFC.
How can i do that?Pls help me..

char szFile[20]={0},szDir[500]={0};
	memset(szFile,0,20);
	memset(szDir,0,500);
	strcpy(szFile,szModelName);
	strcat(szFile,".EXE"); 
	sInfo.lpFile = szFile; 
	sInfo.hwnd = NULL;//this;
	sInfo.lpParameters ="MODEL";
	strcat(szDir,"\\Sources\\");
	sInfo.lpDirectory = szDir;
	sInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
	sInfo.cbSize = sizeof(SHELLEXECUTEINFO);
	sInfo.lpVerb = "open";
	sInfo.nShow  =  SW_HIDE;
	sInfo.hwnd   =  NULL;	
	BOOL bFlag = ShellExecuteEx(&sInfo);

Console application coding

int main( int argc , char *argv[] )
{
	char str[50];
	strcpy(str,argv[1]);
	getch();		
}

You could PostMessage[^] from the console app to the MFC app (or send it using SendMessage[^] - depends on the context).

Hi. I want to ask you an long question : I have an CRectTracker and an CLineTracker , ( base simple projects could be taken from here[TestTracker] and from here[TestLineTracker2] . How can I combine those clases , ( CLineTracker & CRectTracker ) to have a CScrollView with CRect object and CLinePos object , and an line object between two rects keep tracks with rectangles ? A kind of object net map ... see somehere an CMultiRectTracker but for is not sufficient , because I need an LineTracker too , and I like to be an portable code somehow , I mean , if I have an CMultiLineRectTracker class , that class to reuse in any other project... any kind of hint will be appreciated !

Hi sir,
I want to use the arithmetic operation

A = AExp(_0.324 * t/T).

How can i use it in VC++,
The values A,t and T i am reading from controls(edit box)

Thanks

std::exp() is your friend - it takes one parameter and returns e raised to the power of it's argument. It's declared in cmath. With that function you can write your expression in almost the same way as you've written it in the question.

Cheers,

Ash

What is AExp ? You mean A power of ... ?

What is the '_' in front of 0.324 ?

Anyway, I think the only "difficulty" here is the power of functionality, which you can have by calling the pow[^] function.
