81.50.98.20: Apply changes to the registry with an external program

2006-07-02T21:30:01Z

Apply changes to the registry with an external program

New page

<highlight-nsis>
There is another way to apply changes in the registry :
1/ write keys and values like before, eg : WriteRegStr HKCU "Environment" "NAME" "VALUE"
2/ call a simple exe program to apply the changes :
Source code :
</highlight-nsis>

<highlight-c>
#include <windows.h>
#include <stdio.h>

int main( int argc, char** argv)
{
/*
LRESULT SendMessageTimeout(
HWND hWnd,
UINT Msg,
WPARAM wParam,
LPARAM lParam,
UINT fuFlags,
UINT uTimeout,
PDWORD_PTR lpdwResult
);
*/
DWORD lpdwResult;
char* param;
param = "Environment";
int result = SendMessageTimeout(
// window handle => all top-level windows
HWND_BROADCAST,
// message => environment changed
WM_SETTINGCHANGE,
// wParam : additional message-specific information
// When an application sends this message, this parameter must be NULL.
(WPARAM)NULL,
// lParam : additional message-specific information
// lParam is a pointer to a string that indicates the area containing the system parameter that was changed
(LPARAM)param,
// how to send the message
// The calling thread is not prevented from processing other requests while waiting for the function to return.
SMTO_NORMAL,
// uTimeout : time-out period in milliseconds
// duration = uTimeout * number_of_windows (in case broadcast message)
500,
// Receives the result of the message processing
&lpdwResult
);
fprintf(stdout, "SendMessageTimeout returned : %d => %s\n", result, (result != 0) ? "SUCCESS" : "FAILED");
// inverse return code ...
return (result != 0) ? 0 : -1;
}
