I would do (to mimic the extraction of random number from a bag)

void swap (int & a, int & b)
{
  int t=a;
  a=b;
  b=t;
}
//...
  int array[10];
  int n = 10;
  int i;
  for (i = 0; i < n; i++)
      array[i] = i;
   
  for (i = n; i > 1; i--)
  { 
      int j = rand() % i;
      swap( array[i-1], array[j] );
  }

If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Loop .mp3 playback

I'm very new to audio. I stumbled across the following code and I'm using the it to play audio .mp3s in my DX9.0 app. ( Nov 08 SDK )

::CoInitialize(NULL);   
CoCreateInstance(CLSID_FilterGraph, NULL, CLSCTX_INPROC, IID_IGraphBuilder, (void **)&g_pGraphBuilder);   
g_pGraphBuilder->QueryInterface(IID_IMediaControl, (void **)&g_pMediaControl);   
g_pGraphBuilder->AddSourceFilter(L"../Media/Audio/Music/Artifact_CharMain.mp3", L"../Media/Audio/Music/Artifact_CharMain.mp3", &pSource);   
pSource->FindPin(L"Output", &pPin);    
g_pGraphBuilder->Render(pPin);   
pPin->Release();   
g_pMediaControl->Run();

How can I make the .mp3 loop?

Thanks!

I've never worked with the media control. That said, if the COM interfaces provide a feature that you can use to have the control loop the resource that would be the best approach. If it does not, then you will have to code a loop yourself, I guess.

I am creating a VC++ like IDE development environment. I am confused if it is a SDI or MDI like application. I have read in 'Jeff Prosis' book that it is a 'Workspace based' model. I searched on the net for this type of model but didn't get much help. Cry | :((

Can you please guide me on this.

Thanks

Those two statements would seem to be in conflict. A person that does not understand the difference between SDI and MDI cannot have enough experience to develop the project stated in the first sentence.

I have some knowledge of making SDI and MDI applications using SDK windows API's as well as MFC. The project that I am designing now is a tough job for me. The aim of the program is to debug a programming language. It will be having source code open in various windows. There will also be watch and output window like that of VC++ 6.0. My aim is to have single document and multiple views. I want to check if there is any readymade stuff to make this workspace based architecture.

Error compiling call to Windows API function.

Hi
I am working on a CPP that created services.

It complains about the last value in the SERVICE_FAILURE_ACTIONS struct.

According to the Microsoft it is defined as follows:

lpsaActions

A pointer to an array of SC_ACTION structures.

--------------------
When compiling code that calls the function that sets the failure acitons of a server I get the following output.

---------------------------------------------------------------

SC_ACTION *action_array[1];

SC_ACTION* action_str = new SC_ACTION();
action_str->Type = SC_ACTION_RESTART;
action_str->Delay =6000;

action_array[0] = action_str;

SERVICE_FAILURE_ACTIONS actions_struct;
actions_struct.dwResetPeriod = 86400;
actions_struct.lpRebootMsg = NULL;
actions_struct.lpCommand = NULL;
actions_struct.cActions = 1;
LINE(588)---> actions_struct.lpsaActions = action_array;

int result2 = ChangeServiceConfig2W(
service,
SERVICE_CONFIG_FAILURE_ACTIONS,
&actions_struct);

------------------------
OUTPUT

#

Is there something obvious that I am doing wrong here? My CPP is a little rusty. Frown | :(

Would appreciate any help I can get

Change the declaration of action_array from

SC_ACTION *action_array[1];

SC_ACTION action_array[1];

SC_ACTION *action_array = new SC_ACTION[1];

If you were to use the second one, you'd have to deallocate action_array at some point, with

delete [] action_array;

HTH!

Change to:

action_array[0].Type  = SC_ACTION_RESTART;
action_array[0].Delay = 6000;

Help with Mouse Button and counter

Member 23626231-Mar-09 1:33

Member 236262

31-Mar-09 1:33

I'm using Visual C++ and Windows XP
I would like to continuously increment a counter when the left mouse button is down, and then display the number of counts. The basic logic I'm trying to implement is:
count = 0;
while (left_mouse_button_down) count++;

It isn't clear to me how to do something like this in the Windows environment. Any insights would be greatly appreciated.
Thanks David!

If you need this feature only within your application window, it's simply a matter of adding a handler for the mouse click event (WM_LBUTTONDOWN).

If you need this on a global scale (with no regards to which application window has the focus), you need to install a mouse hook. The following resources will get you started:

You didn't say anything about the counter "sensitivity". If you implemented something more or less similar as what you did, your counter would reach an extremely high value in a few miliseconds. What would be the point ? Furthermore it would totally depends on the speed of the computer on which your program is running. Do you need to increase your counter every second ?

Once you defined your sensitivity, you can simply create a timer that fires at your sensitivity rate. You start your timer when the button is pressed and you kill the timer (and display your counter if needed) when the mouse button is released. When the timer fires, you simply increase your counter.

EDIT: by looking at the answer of Rajesh, I'm not sure I understood your question properly. Do you want to count the number of times the user clicks the mouse or do you want to increase your counter while the mouse button is down ? I understood the second one.
