I have previously developed all my source code under VC++ 6.0 under windows 2000.
I have upgraded my PC to XP and have now run into a problem using Following code:

Fun Part is this code works fine in win 2000 but not working in WIN XP:
WHat I am trying to do is when I click the exe file I will show me message that user have 30 days rmains for trial period and register that date (CURRENT DATE) IS FIRST CODE I wrote:

C++

SetAvailability();

COleDateTime timeStart;
// COleDateTime timeEnd(30.0);
COleDateTimeSpan timePassed;
 
int daysLeft = 0;
 
HKEY hk;
DWORD dwDisp;
 
// Open the Registry key, if it doesn't exist, it will be created.
RegCreateKeyEx(HKEY_LOCAL_MACHINE,

0,
NULL,
REG_OPTION_NON_VOLATILE,
KEY_WRITE | KEY_READ,

// Check to see if the product code has been set in the registry entry.
int iRetValProdCode =
RegQueryValueEx(hk,
"USR:App Name\\ProductCode",
NULL,
NULL,
NULL,
NULL);
 
CAddaptApp* pAddaptApp = (CAddaptApp*)AfxGetApp();
 
if(iRetValProdCode != ERROR_SUCCESS)

   DWORD cbData = sizeof(pAddaptApp->m_dwProductCode);
 
   RegQueryValueEx(hk,

      NULL,
      NULL,
      (LPBYTE)&pAddaptApp->m_dwProductCode,
      &cbData);
}
 
if(iRetValProdCode != ERROR_SUCCESS || pAddaptApp->m_dwProductCode == 0)
{ 
   // Check to see if the install date has been set in the registry entry. If it doesn't exist, create
   // the registry entry.
 
   int iRetVal = RegQueryValueEx(hk,

      NULL,
      NULL,
      NULL,
      NULL);
 
   COleDateTime currDateTime = COleDateTime::GetCurrentTime();
 
   if(iRetVal != ERROR_SUCCESS)
   {
      // Registry entry doesn't exist, create it, and set to the current date.
      RegSetValueEx(hk,

   timePassed = COleDateTime::GetCurrentTime() - timeStart;
   daysLeft = 30 - static_cast<int>(timePassed.GetTotalDays());
 
   CString strMessage;
 
   if (daysLeft <= 0)
   {
      CProductCodeDlg dlg;
      dlg.DoModal();
 
      if(pAddaptApp->m_dwProductCode != 0)
      {

The expression "not working" does not help anyone trying to figure out what may be the problem. Please give more detail of exactly what happens versus what you expect to happen.

Albert Holguin 10-Jan-12 13:23pm

Not clear as to what the problem is... clarify.

Solution 1

You are storing a COleDateTime in a DWORD registry entry (32 bit). COleDateTime uses internally the DATE data type which is a double (64 bit).

Good catch! +5

Vijay Pate 11-Jan-12 10:24am

I am actually working on 32 bit apps not 64 bit apps then what should I use.

Thank you very much.

Jochen Arndt 11-Jan-12 10:43am

You may store the day number since 1970-01-01 calculated from time() or _time64(). To store the initial time, save static_cast<int>(_time64(NULL) / (24LL * 3600LL)). To get the elapsed number of days, subtract the integer value read from the registry from static_cast<int>(_time64(NULL) / (24LL * 3600LL)).

Vijay Pate 11-Jan-12 11:05am

being novice I dont even have idea how to write this code could you please help where should I wrote your code.
Thank you very much.

Jochen Arndt 11-Jan-12 11:18am

To store initial value when registry entry does not exist:
DWORD dwStart = static_cast<DWORD>(_time64(NULL) / (24LL * 3600LL));
DWORD cbData = sizeof(DWORD);
RegSetValueEx(hk, "USR:App Name\\FirstInstallDateTime", 0, REG_DWORD,
(LPBYTE)&dwStart, &cbData);
Get elapsed days:
RegQueryValueEx(hk, "USR:App Name\\FirstInstallDateTime", 0, REG_DWORD,
(LPBYTE)&dwStart, &cbData);
DWORD dwPassed = static_cast<DWORD>(_time64(NULL) / (24LL * 3600LL)) - dwStart;
int nDaysLeft = 30 - static_cast<int>dwPassed;

Vijay Pate 11-Jan-12 12:28pm

hi Jochen,
When I copied your code it gave me error after I gave declaration of #include "time64.h"
is Fatal Error C1083: cannot open include file: time64.h: no such file.

Jochen Arndt 11-Jan-12 12:38pm

Which compiler version did you use? Still VC6? Then replace _time64(NULL) by time(NULL) and the 'LL' suffixes by a single 'L'. Using time() does not matter yet (will roll-over in the year 2038). And the term 'Get elapsed days:' has to be removed or commented. It's just text telling you where to insert the code.

Vijay Pate 11-Jan-12 12:48pm

I am still using VC ++ 6.0

Vijay Pate 11-Jan-12 13:06pm

One of the error is:
C:\ADDAPT2000\ADDAPT.EXE\AddaptApp.cpp(298) : error C2065: '_time64' : undeclared identifier

Jochen Arndt 11-Jan-12 13:08pm

As I wrote above: Replace the calls to _time64() by time() and the 'LL' suffixes by a single 'L' with VC6.

after finish writing following Code:

Jochen Arndt 11-Jan-12 14:16pm

Sorry some typos (but you should detect it yourself):

RegSetValueEx(hk, "USR:App Name\\FirstInstallDateTime", 0, REG_DWORD, (LPBYTE)&dwStart, sizeof(DWORD));

RegQueryValueEx(hk, "USR:App Name\\FirstInstallDateTime", 0, NULL, (LPBYTE)&dwStart, &cbData);

Vijay Pate 11-Jan-12 15:10pm

No difference I am getting same error and not able to get this MFC APPLICATION. But Thank you very much.

Vijay Pate 12-Jan-12 8:48am

I am still having same issue for not able to install and able to work while installing it give me assertion error and oletyplb.cpp error and upload is not working correctly.

Jochen Arndt 12-Jan-12 9:03am

That must be other errors. The MFC TypeLibCache is not used by the non-MFC registry functions and the time() function. With assertions, stop debug execution, evaluate the wrong condition, and step back the call stack to find the source of error.

Vijay Pate 12-Jan-12 13:24pm

I am gettting following error when Installing the product:
Debug Assertion Failed
File: oletyplb.cpp
line: 31

Jochen Arndt 12-Jan-12 13:38pm

As I wrote before: That is another error. Please open a new question to solve that problem. If doing so, provide the necessary information (include source lines around line 31 from file oletyplb.cpp located in the MFC source directory of your VC) and be more specific about when the error occurs ('installing the product' is not enough; which product? Why installing?)

Vijay Pate 12-Jan-12 14:01pm

your code worked fine but Instead of vetting AfxmessageBox mentioned in folowing message:
strMessage.Format(_T("ADDapt is operating under a trial license. \n")
_T("You have %d" " days to activate ADDapt with a valid license.\n")
_T("To activate, Please call Avtron Field Service at 216 642-1230 ext 1214. \n")
_T("Do you want to Proceed?"), daysLeft);
I am getting Product code box that not what I am looking for.

Thank you very much.

Vijay Pate 12-Jan-12 14:12pm

I am also having some other issue with window registry when I am activating the product in tgrial period(between zero to 30 days) it is not makning entry in win registry but it works only when trial period end.

Thank you very much

Vijay Pate 16-Jan-12 7:58am

WHile installing the software on PC and at the end of installation. that when oletyp[lb.cpp error came into existance.

Thank you very much.

Vijay Pate 16-Jan-12 8:22am

Could you please help me where should I insert following code in the code I sent you :

DWORD dwStart = static_cast(time(NULL) / (24L * 3600L));
DWORD cbData = sizeof(DWORD);
RegSetValueEx(hk,
"USR:App Name\\FirstInstallDateTime",
0,
REG_DWORD,
(LPBYTE)&dwStart,
&cbData);
//Get elapsed days:
RegQueryValueEx(hk,
"USR:App Name\\FirstInstallDateTime",
0,
REG_DWORD,
(LPBYTE)&dwStart,
&cbData);
DWORD dwPassed = static_cast(time(NULL) / (24L * 3600L)) - dwStart;
int nDaysLeft = 30 - static_cast(dwPassed);

Jochen Arndt 16-Jan-12 8:40am

You should replace some of your code by my example code:

Replace 'COleDateTime currDateTime = COleDateTime::GetCurrentTime();' by the first two lines with the DWORD variables.
Replace the following call to RegSetValueEx() inside the condition by my call.
Replace your code from 'timeStart =...' up to 'daysLeft =...' by the rest of my code (note the I have named the var nDaysLeft). And don't use the code pasted into your above comment. It misses the cast parentheses by pasting text as HTML.

If you couldn't get this to work, I'm sorry. You should know what you are doing and understand the difference between your code and mine.

Vijay Pate 16-Jan-12 8:47am

I have never worked on VC++ 6.0 and I am more in.NET that is only reason I am posting this help .

Although thank you very much for your help.

Jochen Arndt 16-Jan-12 9:00am

No problem. But 'I have previously developed all my source code under VC++ 6.0 under windows 2000.' lets me think that you have some experience.

Regarding the insertion: Think about it. The first block will write the registry entry (should be only done when it does not exist already). The second block reads the start day and calculates the number of days left. The COleDateTime vars are no longer used. Doing so, you will learn. You will not learn when copying code without understanding what it does.

Vijay Pate 16-Jan-12 8:53am

If you change 'int nDaysLeft = 30 - static_cast(dwPassed);' to 'daysLeft = 30 - static_cast<int>(dwPassed);' it may do what you expect that it should do.

Vijay Pate 18-Jan-12 15:20pm

Thank you very much and it worked just fine

Vijay Pate 19-Jan-12 8:01am

your previous note work fine but I got into other issue when I am trying to activate product in trial period I still get following message and does same thing if it is done after trial period over any idea?

Thank you very much

I also need to add the functionality for ProductCode.CPP.
When trial period is over I need Productcode page pop up where activation of product take place and willl register the product and make entry in window registry and end user willl not see any window but main application.

Thank you very much

I'm sorry, but I will not write your hole application. Your last request is rather trivial and you should be able to do it yourself (especially when working on a commercial project). Additionally, it is not related to your initial question. You should create a new question rather than modifying an existing one.

thank you very much

hi Mr. Jochen Arndt

Solution or code you provide me dosen't calculate days

Jochen Arndt 24-Jan-12 3:07am

Some comments above you said that it is working. Now it is not working? You should use debugging with optional trace outputs to see what your code does. Then you can determine the content of all variables at each program code location.

Thank you again. But I have already done that.

patelv61 26-Jan-12 10:12am

When I insert your code everything workd but calculation of days stop working. where did I made mistake?

Please indicate in your next comments or answer.

Thank you very much.

Jochen Arndt 26-Jan-12 10:22am

I did not know where you make a mistake, because I did not know your actual code. Before posting again a lot of code lines here in the comment section: Please imagine that reading and verifying this unformatted code is much more difficult for me than for you using an editor.

Again: Use debug mode and put TRACE calls into your code to print all values at different locations. Then you will see where your vars did not contain the expected values.

Hi Jochen Thank you for your help and I like to confirm the code you sent me 1 1/2 week ago looks correct or not:

SetAvailability();

COleDateTime timeStart;
COleDateTimeSpan timePassed;

int daysLeft = 0;

HKEY hk;
DWORD dwDisp;

// Open the Registry key, if it doesn't exist, it will be created.

RegCreateKeyEx(HKEY_LOCAL_MACHINE, "SOFTWARE\\AVTRON MANUFACTURING\\ADDAPT\\PARAMETERS",
0,
NULL,
REG_OPTION_NON_VOLATILE,
KEY_WRITE | KEY_READ,
NULL,
&hk,
&dwDisp);

// Check to see if the product code has been set in the registry entry.
int iRetValProdCode =
RegQueryValueEx(hk,
"Activated ProductCode",
NULL,
NULL,
NULL,
NULL);

CAddaptApp* pAddaptApp = (CAddaptApp*)AfxGetApp();

if(iRetValProdCode != ERROR_SUCCESS)
{
DWORD cbData = sizeof(pAddaptApp->m_dwProductCode);

RegQueryValueEx(hk,
"Activated ProductCode",
NULL,
NULL,
(LPBYTE)&pAddaptApp->m_dwProductCode,
&cbData);
}

if(iRetValProdCode != ERROR_SUCCESS || pAddaptApp->m_dwProductCode == 0)
{
//Chack to see if the install date has been set in the registry entry.
// IF it dosen't exist create
// the registry entry
DWORD dwStart = static_cast<dword>(time(NULL) / (24L * 3600L));
DWORD cbData = sizeof(DWORD);
int iRatVal = RegSetValueEx(hk,
"FirstInstallDateTime",
0,
REG_DWORD,
(LPBYTE)&dwStart,
sizeof(DWORD));

//COleDateTime currDateTime = COleDateTime::GetCurrentTime();

//if(iRetVal !=ERROR_SUCCESS)
{

//Get elapsed days:
int iRetVal = RegQueryValueEx(hk,
"FirstInstallDateTime",
0,
NULL,
(LPBYTE)&dwStart,
&cbData);
DWORD dwPassed = static_cast<dword>(time(NULL) / (24L * 3600L)) - dwStart;
int nDaysLeft = 30 - static_cast<int>(dwPassed);

}
//timeStart = COleDateTime::GetCurrentTime();
CString strMessage;

if (daysLeft <= 0)
{

CProductCodeDlg dlg;
dlg.DoModal();

if(pAddaptApp->m_dwProductCode != 0)
{
// Create the product code registry entry.
RegSetValueEx(hk,
"Activated ProductCode",
0,
REG_DWORD,
(LPBYTE) &pAddaptApp->m_dwProductCode,
sizeof(pAddaptApp->m_dwProductCode));

}
else
{
return FALSE;
}

}
else
{

strMessage.Format(_T("ADDapt is operating under a trial license. \n")
_T("You have %d" " days to activate ADDapt with a valid license.\n")
_T("To activate, Please call Avtron Field Service at 216 642-1230 ext 1214. \n")
_T("Do you want to Proceed?"), daysLeft);

int iRespVal = AfxMessageBox(strMessage, MB_YESNO | MB_ICONEXCLAMATION);

// User selected No, close the application.
if(iRespVal == IDNO)
{

return FALSE;
}
}
}

Please, please try it yourself.
However:

'if(iRetValProdCode != ERROR_SUCCESS)'
This is executed when the reg value 'Activated ProductCode' does not exist. But then you try to read the same value. That can not be your intention! I think you should write the value here!

'if(iRetValProdCode != ERROR_SUCCESS || pAddaptApp->m_dwProductCode == 0)'
Here you are writing the start date if the above key does not exist or the product code is 0. I can't know if this is what you want. Maybe you should change your complete code to write the start date only when the start date entry does not exist.
Then you read the start date value, but you have just written it. So it will be always the same date, resulting in 30 days left. Reading the start date value must be out of that scope.

'int nDaysLeft = 30 - static_cast(dwPassed);'
In some prior comments i wrote that you must replace this by 'daysLeft =...'.

'if(iRespVal == IDNO)'
You should use 'if(iRespVal != IDYES)' because IDCANCEL may be also returned when closing the box.
