Very easy - just handle the clicking of the button ( in class wizard ) and PlaySound(filepath, NULL, SND_NODEFAULT);
ShellExecute will allow you to run an app programatically - from MSDN:
HINSTANCE ShellExecute(
HWND hwnd,
LPCTSTR lpVerb,
LPCTSTR lpFile,
LPCTSTR lpParameters,
LPCTSTR lpDirectory,
INT nShowCmd
);
Parameters
hwnd
Handle to a parent window. This window receives any message boxes that an application produces. For example, an application may report an error by producing a message box.
lpVerb
A string, referred to as a verb, that specifies the action to be performed. The set of available verbs depends on the particular file or folder. Generally, the actions available from an object's context menu are available verbs. For more information about verbs and their availability, see Object Verbs. See Extending Context Menus for further discussion of context menus. The following verbs are commonly used: Verb Description
edit Launches an editor and opens the document for editing. If lpFile is not a document file, the function will fail.
explore Explores the folder specified by lpFile.
find Initiates a search starting from the specified directory.
open Opens the file specified by the lpFile parameter. The file can be an executable file, a document file, or a folder.
print Prints the document file specified by lpFile. If lpFile is not a document file, the function will fail.
properties Displays the file or folder's properties.
If you set this paramater to NULL:
For systems prior to Microsoft® Windows® 2000, the default verb is used if it is valid and available in the registry. If not, the "open" verb is used.
For Windows 2000 and later systems, the default verb is used if available. If not, the "open" verb is used. If neither verb is available, the system uses the first verb listed in the registry.
lpFile
Address of a null-terminated string that specifies the file or object on which to execute the specified verb. To specify a shell namespace object, pass the fully-qualified parse name. Note that not all verbs are supported on all objects. For example, not all document types support the "print" verb.
lpParameters
If the lpFile parameter specifies an executable file, lpParameters is an address to a null-terminated string that specifies the parameters to be passed to the application.The format of this string is determined by the verb that is to be invoked. If lpFile specifies a document file, lpParameters should be NULL.
lpDirectory
Address of a null-terminated string that specifies the default directory.
nShowCmd
Flags that specify how an application is to be displayed when it is opened. If lpFile specifies a document file, the flag is simply passed to the associated application. It is up to the application to decide how to handle it.
SW_HIDE Hides the window and activates another window.
SW_MAXIMIZE Maximizes the specified window.
SW_MINIMIZE Minimizes the specified window and activates the next top-level window in the z-order.
SW_RESTORE Activates and displays the window. If the window is minimized or maximized, Windows restores it to its original size and position. An application should specify this flag when restoring a minimized window.
SW_SHOW Activates the window and displays it in its current size and position.
SW_SHOWDEFAULT Sets the show state based on the SW_ flag specified in the STARTUPINFO structure passed to the CreateProcess function by the program that started the application. An application should call ShowWindow with this flag to set the initial show state of its main window.
SW_SHOWMAXIMIZED Activates the window and displays it as a maximized window.
SW_SHOWMINIMIZED Activates the window and displays it as a minimized window.
SW_SHOWMINNOACTIVE Displays the window as a minimized window. The active window remains active.
SW_SHOWNA Displays the window in its current state. The active window remains active.
SW_SHOWNOACTIVATE Displays a window in its most recent size and position. The active window remains active.
SW_SHOWNORMAL Activates and displays a window. If the window is minimized or maximized, Windows restores it to its original size and position. An application should specify this flag when displaying the window for the first time.
Return Values
Returns a value greater than 32 if successful, or an error value that is less than or equal to 32 otherwise. The following table lists the error values. The return value is cast as an HINSTANCE for backward compatibility with 16-bit Microsoft® Windows® applications. It is not a true HINSTANCE, however. The only thing that can be done with the returned HINSTANCE is to cast it to an integer and compare it with the value 32 or one of the error codes below.
0 The operating system is out of memory or resources.
ERROR_FILE_NOT_FOUND The specified file was not found.
ERROR_PATH_NOT_FOUND The specified path was not found.
ERROR_BAD_FORMAT The .exe file is invalid (non-Win32® .exe or error in .exe image).
SE_ERR_ACCESSDENIED The operating system denied access to the specified file.
SE_ERR_ASSOCINCOMPLETE The file name association is incomplete or invalid.
SE_ERR_DDEBUSY The DDE transaction could not be completed because other DDE transactions were being processed.
SE_ERR_DDEFAIL The DDE transaction failed.
SE_ERR_DDETIMEOUT The DDE transaction could not be completed because the request timed out.
SE_ERR_DLLNOTFOUND The specified dynamic-link library was not found.
SE_ERR_FNF The specified file was not found.
SE_ERR_NOASSOC There is no application associated with the given file name extension. This error will also be returned if you attempt to print a file that is not printable.
SE_ERR_OOM There was not enough memory to complete the operation.
SE_ERR_PNF The specified path was not found.
SE_ERR_SHARE A sharing violation occurred.

Eh... 
The sound section look easy but.. i cant get it to work, will you please make a litle example cuz i cant figure it out.... 
|
|
|
|

Look up this function in the windows api documentation:
BOOL PlaySound(LPCSTR pszSound, HMODULE hmod, DWORD fdwSound );
usage:
::PlaySound("C:\\SOUNDS\\BELLS.WAV", NULL, SND_SYNC|SND_NODEFAULT); //plays "bells.wav"
See the topic "Waveform audio" in the Visual Studio documentation.

Hmmm
still cant get it to work right, this is what i did with a butten....
void CTestSoundDlg::OnSoundtest()
{
BOOL PlaySound(LPCSTR pszSound, HMODULE hmod, DWORD fdwSound );
PlaySound("C:\\TEST.WAV", NULL, SND_SYNC|SND_NODEFAULT); //Sound Test
}
And here is the error i get 
C:\My Documents\C++\TestSound\TestSoundDlg.cpp(177) : error C2065: 'SND_SYNC' : undeclared identifier
C:\My Documents\C++\TestSound\TestSoundDlg.cpp(177) : error C2065: 'SND_NODEFAULT' : undeclared identifier
Error executing cl.exe.
TestSound.exe - 2 error(s), 0 warning(s)
Hmmm i think i need some more help, i cant figure out what i did wrong..
Thanks

Your line compiles fine in my code, so I don't know why it doesan't in yours, butaccording to MSDN:
Windows NT/2000: Requires Windows NT 3.1 or later.
Windows 95/98: Requires Windows 95 or later.
Header: Declared in Mmsystem.h.
Library: Use Winmm.lib.
Unicode: Implemented as Unicode and ANSI versions on Windows NT/2000.
but I assume that you have your includes OK, otherwise it wouldn't recognise the command. The constant values of the two flags you're using are 0x0000 and 0x0002, so try putting the numberical value instead, just to see if that compiles and runs. The problem is obviously that your environment is unaware of the definition of the two constant values.

Two things could be missing:
1- You did not include this line >mmsystem.h< in the stdafx.h
2- You did not include/link to the WINMM.LIB in the linker ALT+7 list.
Try and should work fine-> coz the code is good!

I suggested that too, but if it's a lib error, it should know the constants defined and fail in the link stage, and if it's the #include, how come it knows PlaySound, but not the constants ?

Anyone out there written anything to do byte order swapping?
I have a mixed file containing both Big endian and Little endian 32 bit integers. I read the u_long ntohl(u_long network) function in winsock2.h but it does not give me the correct value back when I swap it. I tried this and got mixxed result based on reading by char 1 2 3 and 4 times.
union byte4
{
int I;
char ch[4];
}
did swap with this function
byte4 swap(byte4 in)
{
byte4 swp;
swp = in;
in.ch[0] = swp.ch[3];
in.ch[1] = swp.ch[2];
in.ch[2] = swp.ch[1];
in.ch[3] = swp.ch[0];
in.ch[4] = NULL;
return in;
}
Any ideas whats going wrong here?

Hello mate,
This is what I use and it works 
DWORD ReverseByteOrder(DWORD* pdwRaw)
{
unsigned char c[4];
memcpy( &c, pdwRaw, 4);
DWORD dwReturn = c[3] | (c[2] << 8) | (c[1] << 16) | (c[0] << 24);
return dwReturn;
}
Hope this helps!

Is there a way, to place a CFileDialog into a Propertysheet. I now there is a way, MS did it!
Please help
Sjoerd
|
|
|
|
|
MS did not use the propertysheet in a dialog. If you are refering to the
file/project dialogs in VJ++/InterDev 6.0 then take a closer look.
It is the normal tab control in the extended CFileDialog with the controls
hidden or shown depending on which tab you click--this is the normal tab control operation.
Regards,
Paul.

I did see it. So what I really have to do is when other tabs are selected that per example the "OPEN" tab, is hiding some or all controls of the CFileDialog, and bring new ones fore.
Sjoerd
|
|
|
|
|
Right. You can make it even easier by inserting thin dialogs on the tab control, this way hiding the dialog hides all the controls--just anything you can do with the standard Windows tab control is ok.

Paul.

Is there any control in MFC that lets you view the directory tree of your drive or a listview of files in certain directory?
If not, how can I build a list of that kind? What functions can i use? And how can I get the icons for each file listed?
Basically, i would want my app to look a bit like ACDSee, but for another purpose of course.
Thanx in advance!

Hello,
There is no MFC class by MS to do what you wish. However, a lot of codes exist
at the codeguru site to help. You can take a look at the following code too

Paul.

Hi,
We are using dao to connect to various typses of databases, access, oracle, and sql server. This way our clients can choose which one they want to use. We have just encountered a problem, where one of our clients tables has over 255 fields. They are using sql server. Sql Server allows you to create tables with up to 1000 fields, but using dao to access them will only allow you to create recordsets with up to 255 fields! I believe that I can't even select from TWO tables that will end up in a recordset with more than 255 fields. Does anyone have any ideas as to how to get around this problem? 
Thank You

The problem lies deeper than DAO. The Jet database engine only supports 255 fields per table so you might be out of luck

Hi,
I would like to learn a bit more about programming and would like
to focus on client-server application.
Does anyone know about tips and pointers where I can learn more about
this. I would like to know what it takes to write an application like,
say ArcServe, with a set of services running on the server and a
desktop application on the client side.
Cheers.

Hi there, I'm making a typelibrary with ATL for visual basic users. Does anyone know how you can create a static function so that it appears in the <globals> section when i look at my library with the objectbrowser in VB ?

Hi,
Just a small query:
I want to check if a certain module (.exe, i know its path) is running ? (VC++)
Thanks a lot.
|

If you are writting the other module try creating named Mutex
// Create named mutex
hNamedMutex = CreateMutex(NULL, TRUE, "The Other App");
// Test if the programm is already running
if(GetLastError() == ERROR_ALREADY_EXISTS) {
// Do Somthing
}
If you don't ...
the you have two approaches one is to enumerate the windows by using The EnumWindows function which enumerates all top-level windows on the screen by passing the handle to each window, in turn, to an application-defined callback function. EnumWindows continues until the last top-level window is enumerated or the callback function returns FALSE
If you want to enumerate the processes.
Under Windows 95, you must use functions from the ToolHelp32 group of APIs. Under Windows NT, you use functions from PSAPI.DLL, which is available in the Platform SDK.
// Sample Code FOR NT
#include <windows.h>
#include <stdio.h>
#include "psapi.h"
#pragma comment (lib, "psapi.lib")
void PrintProcessNameAndID( DWORD processID )
{
char szProcessName[MAX_PATH] = "unknown";
// Get a handle to the process.
HANDLE hProcess = OpenProcess( PROCESS_QUERY_INFORMATION |
PROCESS_VM_READ,
FALSE, processID );
// Get the process name.
if ( hProcess )
{
HMODULE hMod;
DWORD cbNeeded;
if ( EnumProcessModules( hProcess, &hMod, sizeof(hMod),
&cbNeeded) )
{
GetModuleBaseName( hProcess, hMod, szProcessName,
sizeof(szProcessName) );
}
}
// Print the process name and identifier.
printf( "%s (Process ID: %u)\n", szProcessName, processID );
CloseHandle( hProcess );
}
void main( )
{
// Get the list of process identifiers.
DWORD aProcesses[1024], cbNeeded, cProcesses;
unsigned int i;
if ( !EnumProcesses( aProcesses, sizeof(aProcesses), &cbNeeded ) )
return;
// Calculate how many process identifiers were returned.
cProcesses = cbNeeded / sizeof(DWORD);
// Print the name and process identifier for each process.
for ( i = 0; i < cProcesses; i++ )
PrintProcessNameAndID( aProcesses[i] );
}
Hope this helps
Cheers
