Hello guys...
Now, i am currently working to develop an application for my school project. My project is making communication between two computer via telephone line using modems.I wanted to enhance my application, and here is my question :
How do I add an event sound to my application? (i.e. when one computer making call to another, and its receive "RING" message from modem and produce sound (ring.wav)
->> I mean, when one computer receive "RING" message (its shows in edit box), i want the computer produce ringing tone.(some sound alert for the user)
Beside that, when the transfer of data is complited, the computer produce sound for this event.
I have surfed the web for examples and tutorials, but majority of them seem to be a little too advance for me. If someone out there can explain the basics to me, along with a simple example, I would really appreciate it.

In your .cpp file you have to include mmsystem.h and link to the winmm library. You can then use PlaySound to play .wav files.
#include <mmsystem.h>
#pragma comment (lib, "winmm.lib")
.
.
.
PlaySound(_T("Ring.wav"), NULL, SND_ASYNC | SND_FILENAME);

woun't compile ,
here it is:
#include
using std::cout;
using std::endl;
template<int n="">
class CalculateCycle
{
public:
enum { count = CalculateCycle&t N % 2 ?
(N * 3 + 1) : (N / 2) >::count + 1 };
};
template <>
class CalculateCycle<1>
{
public:
enum { count = 1 };
};
int main(int argc, char* argv[])
{
const int iNo = 22;
cout << "Cycle length of " << iNo << " is = "
<< CalculateCycle<ino>::count << endl;
return 0;
}
the article is called
Template Meta-programming
please help, what can I do ?
// Lord Byte has started to code
void swap(char **p, char **q)

Try looking up the functions fopen(), fprintf(), and fclose().

Its an image of my private project. I'm still a beginner an so I have several questions.
First some word about the structure of my application. It is a single doc app created with the VC++ 6.0 project wizard. At the right site you see the applications docview. It contains a CListCtrl. At the left side I managed to add a CDialogBar with a dialog conaining a CTabCtrl. If you switch the tabs the checkbuttons and texteditfields will be activated or deactivated.
Now my questions:
1) I want to manipulate the CListCtrl from within the CDialogBar dialog. If you push the start button some processing should be done and the result should be displayed in the right View. How can I do this? As I see it there is no way to give the doc or view class access to the dialogbar class and the other way too. 
2) Isn't there an easy and simple example of an application that uses register cards and diffent dialogs on every page? You know like the preferences dialog unter Visual C++ -> Project -> Preferences ? Or think about the tiny search program for Windows 95, 98, 2000?  It has all elements I need for my application. Different Dialogs with a propertysheet, and the result of the processing is displayed in an explorerlike Listview. Although it is just a simple application I did not see sourcecode for a similar program.
Thank you for your time and help! ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

For MFC SDI applications :
((CFrameWnd*)AfxGetMainWnd())->GetActiveView() return pointer to you CView class,
((CFrameWnd*)AfxGetMainWnd())->GetAcviteDocument() return pointer to you CDocument class.

That simple... I read "MFC in 21 days", and they mentioned it earlier but I forgot. Sometimes I wonder if I will ever get used to the whole document - view and message concept of MFC. Think about that, there is no member for the CYOURDoc and CYOURView in any class in your whole project.
Thank you again!

do you know c++ class ? 
<br />
class CYOUView : public CView<br />
{<br />
int m_int;<br />
};<br />
If you try compile that string:
<br />
... GetActiveView()->m_int ...<br />
you got error "m_int not member of class CView"
but if you write:
<br />
... ((CYOUView*)GetActiveView())->m_int ...<br />
that will compile, and work whith no error's

Hi All,
I'm sure this has been asked coutnless times before but i'm buggered if i can find the answer anywhere.
Got an MFC dialog app. I want to DoModal on the first dialog, and then if the ok button was clicked, create a different dialog and DoModal on that.
But the second dialog just returns immediately.
Any ideas?
Jon

Remove m_pMainWnd assigment from CWinApp::InitInstance and will work
|
|
|
|
|
make sur the second dialog is a member variable of the first dialog class. and is created with new, not just created on the stack in the function that creates the second dialog.
something like
m_pSecondDialog = new MySecondDialogClass;
m_pSecondDialog->Create( ... );
instead of
MySecondDialogClass dlg;

I was using the code for high color bitmaps in "http://www.codeguru.com/Cpp/G-M/bitmap/article.php/c1721/" and i created a class which can be used for image loading and displaying from a resource the CBitmap and Cpalette are member vars of the class .
I used the class in a game where there are different levels and the number of images is incresed as the level increases then i noticed that the program occasionaly faces the from of creating a compatible dc then i noticed that using the resource meter that level after level the GDI resource is falling in the class destructor i used detach and deleteObject for each CBitmap and Cpalette member but the gdi resource starts falling to a critical level and thats when the program fails to create a compatible dc after closing the window the GDI is restored to its orignal level but as the level increases the GDI level falls?????
what can be done after each level to restore the GDI resources

|

Any GDI object that you select into a device context must be selected out of the device context before you can delete it. The easiest way to do this is to use the SaveDC and RestoreDC functions.
CDC MemDC;
MemDC.CreateCompatibleDC(NULL);
int Saved = MemDC.SaveDC();
MemDC.RestoreDC(Saved);
Also have a look at http://www.codeproject.com/gdi/csavedc.asp[^]

Thanks a lot
But on the artice u pointed out i saw a thread that says these GDI leaks are on win 9X systems only !
And i have win 98 what do u know about this
|
|
|
|
|
These types of resource leaks occur on all versions of windows. That false rumor is spread because NT based systems have a much larger limit on the number of available GDI handles. So a leak on 9x will crash your app a lot quicker than a leak on NT/2K/XP, but they will crash your app if your app runs long enough.

Hi,
you can use the PlaySound(..) function. Have a look @ the following link which contains a sample which uses this function

Hi dudes,
I have a small problem with my tree control. I want to know how to get the text of the Item of the tree control when the user right clicks on it.
I tried with the GetSelectedItem(). But it is not working because user when right clicks on items of the tree control it is not considered as selected.
Thanks in Advance.
best Regards,
Deliver

In OnDraw, I use font on the pDC, and it works fine, But when printing and print preview , it didn`t do the font. Where should I attach the font to the printing DC, and why, Thanks

You can attach HDI objects to a printer DC in OnPreparePrinting OR OnBeginPrinting Handlers. If you want to do it in OnDraw, you can check if DC is printing or not by using
if(pDC->IsPrinting())
After that, you can do what you want with DC.

well, you better see some printing tutorials for this. Too much already available on printing stuff.
