Strictly speaking you will be running the destructor(s) of PropertyItem(s) if you don't.
Actually, you are just lucky it works without. Change compiler and it might break. (Not very likely, I know)

So, what have you written so far ? What is your problem ?
Sorry, but noone is going to study your requirements nor write code for you.
You have to help yourself a bit, define what are your requirements, try to develop a skeleton app from where you can progress.
Then, when you have a specific problem/question, you can come back here and ask for help.

Well you still have not described your problem.
I must get a clever new signature for 2011.

Plus :
Did you try what had been told to you in this post ?
Please don't create a new thread for a question you still posted. It's a very rude attitude and you won't get much from it.

hello guys... im trying to store time in sql database using ADO. Now im using ctime() to get time and then send it as arguments in function to be stored. But it show the following error
Conversion failed when converting Datetime from character string
NOTE:Datatype of this column is DateTime in Sql Server. Here is my code to get time
char time1[60] = "";
time_t sTime;
time(&sTime);
strcat(time1,ctime(&sTime));
printf("the time is:\t %s", time1);
Database db;
db.InsertRec(time1);
Now Here is the code for the function which inserts record in the database-----db.InsertRec()
char sTime[60] = "";
strcat_s(sTime,time1);
char query[100] = "INSERT INTO Tracks VALUES('";
strcat_s(query,sTime);
strcat_s(query,"')");
try
{
recordset->Open(query, connection.GetInterfacePtr(),ADODB::adOpenForwardOnly,ADODB::adLockReadOnly,ADODB::adCmdText);
}
catch(_com_error &e)
{ printf("\n\n%s", (LPCSTR)((_bstr_t)e.Description())); }
recordset->raw_Close();
what can be the problem?? thnx

That seems a fairly clear message. Your database expects a DateTime value and you are sending it a string.

When I google it than I find why this error comes:
This error message appears, when SQL Server cannot convert a string to a valid DATETIME value. Check here -> [^]
Here is Sample[^] application that uses DateType value.

Print that query and enter it in e.g. SQL Server Enterprise Manager, and play with it there. I think that the date/time was not formatted the way the server expected it to be - e.g. "17.02.2011" instead of "2/17/2011". Fortunately, you tried it today, and not a week ago, as only a wrong value would have been recorded in the database.
If possible, change to parameterized queries - they will handle that scrap for you.

I am trying to access this key in my code (which is a Windows Service and is launched with admin privilege):
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Capture
and I keep getting the error code 5 (ERROR_ACCESS_DENIED).
I followed this solution[^] to adjust the token privilege. This step succeeded, but then RegOpenKeyEx still returned ERROR_ACCESS_DENIED.
What else should I do to access this key?
Thanks in advance.

Hi Cool_Dev,
I roughly had a glance on the discussion thread just now. In the thread, they came out with the solution using manifest file, right?
Answering to your question: Yes, I am on Windows 7 32-bit platform. My code is to be compiled with VC++6 and WDK 6000. So manifest files might not be the solution to this issue ... I guess.

That thread says that the error code 5 can be ERROR_CANTWRITE also. Have a look into it. you can ensure it by checking the value got in in PHKEY argument.
Also try using KEY_ALL_ACCESS Or KEY_WOW64_64KEY in RegOpenKeyEx.

Hi Cool_Dev,
1) The name KEY_WOW64_64KEY is not defined in VC++ 6. So I did not add it since the compiler said "undeclared identifier".
2) RegOpenKeyEx returns value 0 in the PHKEY argument.
3) I have been using KEY_ALL_ACCESS all the time.
4) During run-time seen on the debugger, ERROR_ACCESS_DENIED is 0x0005 and ERROR_CANTWRITE is 0x03F5.
Please refer to the screenshot[^] on VC++2005 remote debugger.

Hi Maxwell,
Its not an answer but I have one doubt.
Are you sure that your application is launched with admin priviledge ?? I am also doing the same in Windows Service and it is working fine in XP, Windows 7 and Vista.
If my application is not lauched with admin priviledge than i get access denied error else it is working fine.

Hi Shilpi,

I think so. I right-click on the Command Prompt shortcut, and choose "Run as Admin", to open a DOS-box. And then I type the command:
MyService.exe -r
to setup and start the service.

I don't think that means the service will run as admin, though.
When the service is installed, it determines what user it will run as.
Open Task Manager, find the process that represents your service and check what user account it is running under.
The difficult we do right away...
...the impossible takes slightly longer.

Hi Richard,
My service is running under the name SYSTEM.
(The logon session user account is "user".)

Nops if He open command prompt as "run as admin" mode and run application than it means that its application is also run as admin mode.

Something like
DWORD dwWritten;
BOOL result = WriteFile(hFile, &st, sizeof st, &dwWritten, NULL);
Use a similar form to read it back.

You probably meant to use _tcscpy() here instead.
