CreateWaitableTimer

1. Create

HANDLE hTimer = CreateWaitableTimer(NULL,FALSE,NULL);

2. Set

LARGE_INTEGER liDueTime;
const int nTimerUnitsPerSecond=10*1000*1000; // the unit of timer is 100 nano seconds
// Set the event the first time 2 seconds after calling SetWaitableTimer
 liDueTime.QuadPart= -(STARTTIMERAFTERSECOND * m_nTimerUnitsPerSecond );
int nTimerInterVal = 10;

SetWaitableTimer(hTimer,&liDueTime, (nTimerInterVal*nTimerUnitsPerSecond), NULL, NULL, false);   


3. Use

// Wait for the timer.
if (WaitForSingleObject(hTimer, INFINITE) != WAIT_OBJECT_0)
        printf("WaitForSingleObject failed (%d)\n", GetLastError());
else printf("Timer was signaled.\n");

Detect microphone VC++, waveInGetNumDevs

An easy way to detect the number of waveindevice using waveInGetNumDevs function

#include <Mmsystem.h>
#pragma comment( lib, "Winmm.lib" )

UINT nDevices =     waveInGetNumDevs();

[InstallScript] MsiGetProperty, MsiSetProperty

There's a function to get value from  Property in installscript

MsiGetProperty (hMSI, "ProductCode", szProductCode, numSize);

or set property


MsiSetProperty(hMSI, "NeedScheduleReboot", "1")   ;

this example show how to set reboot after installation

There's no Installation Interview in project assist panel  within a Installscript MSI project.


To modify which dialog boxes are displayed by modifying the OnFirstUIBefore event in the InstallScript view.

Dialog with SysLink control create fail

Using VS2008 SP1, adding a SysLink Control into a dailog and everything is fine in DEBUG mode.

When running in release mode.... something goes wrong, the dialog won't show up and return -1 fail code...

I traced this problem for a while i found it is the problem of SysLink

I saw a blog http://twigstechtips.blogspot.com/2010/03/c-dialogs-with-syslink-control-do-not.html 

The main reason the Syslink causes the DialogBox() command to fail is because it requires unicode text support, starting from ComCtl32.dll 6. 

add this code will solve the problem
