If you are not getting any help, even though you post several times, you can probably conclude that noone has any example of what you want to accomplish.

You might want to see if there is any help in your Installshield documentation - there might even be a sample project. You might want to try the Installshield site. You could try Google or any other search engine.

Changing the volume of my App only.

Hi I use waveOutSetVolume API to set the volume of the wave out audio I play in my application.
MSDN says : If a device identifier is used, then the result of the waveOutSetVolume call applies to all instances of the device. If a device handle is used, then the result applies only to the instance of the device referenced by the device handle.

So I use the handle I get from waveOutOpen API to change the volume of my Applcation not the system wide sound..
Simply this does not work as intended and the system wave volume changes and my code affects other programs..

code :

//in declarations :
HWAVEOUT m_WaveHandle;

//openning : 
waveOutOpen(&m_WaveHandle,WAVE_MAPPER,&m_wfx,hThread->m_nThreadID,NULL,CALLBACK_THREAD);

//Setting volume :
MMRESULT res;
res=waveOutSetVolume(m_WaveHandle,MAKELONG(leftVol*0xFFFF/100,rightVol*0xFFFF/100));

any ideas to solve this ?
I use Win2000/VC++6.0

WaveOut Problems in Windows application

I have been playing around with Wave files, and I have a little console application that plays a wave file. It works fine. I wanted to create a Windows application that did the same thing, but every time I try to compile it I get a ton of errors saying that HWAVEOUT, WAVEHDR, WAVEFORMATEX and WAVEOTCAPS have a syntax error (C2061). I made sure that I copied all of the includes exactly as they are in the console app. I can't figure out why the compiler does not know about these types. Could anyone please shed some light on the situation? Thanks!

I'd suggest studying an existing scripting project like Macroquest[^]

You're welcome, I'm glad I could help. I don't know much about scripting though, I just know of Macroquest because I saw it mentioned in a blog a couple days ago.

I build a empty project of win32 application and want to constuct a dll by it(just a try),my codes as follow:

#include <windows.h>
HINSTANCE g_hinstThisDll = NULL; // Our DLL's module handle
UINT g_uDllLockCount = 0; // Count

BOOL APIENTRY DllMain ( HINSTANCE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved )
{
switch ( ul_reason_for_call )
{
case DLL_PROCESS_ATTACH:
{
g_hinstThisDll = hModule;

DisableThreadLibraryCalls ( hModule );
}
break;

case DLL_PROCESS_DETACH:
break;
}

return TRUE;
}
I have set the Project->Settins->Link->OutPut:EntryPoint:DllMain and set Project->Settins->Debug:Win32.dll,But there is a link error:unresolved external symbol _main.
now I want to know whether this method is practical or not

if you want to create a DLL, start with a Win32 DLL project, not with a Win32 Application project.

there is more to a DLL than just a DLLMain. you also have to tell the linker to make a DLL and not an EXE . there may be other things, too. but that's what VC takes care of when you select a DLL project.

How to rename the CButton object?

I am a beginier with c++ and I was reading an article to make an XP button, and I don't know how to rename the CButton... can any one help?

Goto your dialog class header file (*.h) that contains the button you want to change to XP style.
It will be like this :
----------------------------------------
class CMyDialog : public CDialog
{
public:
.
.
CButton m_btn;
.
.
.
};
----------------------------------------

Change "CButton" word to your XP style button class name.
For example : CButton -> CXPButton.

Don't forget to include your XP style button class header before this dialog class header.
For example : #include "XPButton.h"

May be compiler can't find "definition" of constructor and destructor. Check your constructor and destructor for its completeness and validness declaration (usually in .h file) and definition (usually in .cpp file).

If it still can't help, confirm me.

how to position child window OnInitialUpdate()

elephantstar23-Jul-04 12:23

elephantstar

23-Jul-04 12:23

I need to position my child window (formview) at position 0,0 each time it starts up. I tried the line of code below but it doesn't seem to do the trick.

SetWindowPos(NULL, 0, 0, -1, -1,SWP_NOSIZE | SWP_NOZORDER | SWP_NOACTIVATE);

Without the code, its position is set at 0,0. But each time I open that same window up, it keeps changing to the next cascading position. How can I prevent this and have it start at position 0,0 each time?

Thanks!

You are supposed to do this by modifying the CREATESTRUCT in PreCreateWindow, so:

BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
  if( !CFrameWnd::PreCreateWindow(cs) )
    return FALSE;
  // TODO: Modify the Window class or styles here by modifying
  //  the CREATESTRUCT cs

  cs.x = 0;
  cs.y = 0;

  return TRUE;
}

I inserted the above code and it still doesn't work. Each time I close the window and open it back up again, it moves to the next cascading position. I tried inserting similar code into BOOL CChildFrame::PreCreateWindow(CREATESTRUCT& cs) and it gives me the same result.
