I want to Create a Process with CreateProcessAsUser from as PrintMonitor running under the System Account
Hello,
I want start a application from a Portmonitor after finisch the Print of the document. Currently i start the application with createprocess but the application running under the system account and has no access to the My Files Directory and the MAPI interface and so on, only acces to the Files or Directorys with "Allow All" access rights.
I need to start the application with the rigths from the logged on user.
i have found many sample and notes with create user but i must given them a user account name and passwort with domain but i will to start the application on the desktop of the logged on user with the rights of this user. the samples i have found to do this without given of a username, password do not work.
This Portmonitor is a part of a Printerdriver you can easy print on in and it make a pdf for you to save or mail it. If the PDF System finished it will be distributed under the GPL.
The Printerdriver, Portmonitor and Application working fine but the problem with the rights under system account is open.
Thanks for help me.
Sorry for bad english.

Is there a simple way to detect if its the first time an app is being run ? i want to display a license agreement without an installer program, my app is dialog based, if it matters.
Cheers

Typically I have apps that create either registry or an ini entry. So I just detect whether this has occurred. Another way would be for your app to create or delete a dummy file in the program's own directory.
Another way would be to compare the time the app is downloaded to the time of the running. But this would be quite imprecise.
I don't think their is any API IsFirstRun() function in the system.

I need to replace the WinMain implemented in MFC, by my own WinMain to encapsulate MFC initialization within the win32 service entry point function.
Does anybody got any clue?

You need to tell the linker to use your WinMain version, which is done via the "Entry-point symbol" box inside Project Settings/Link/Output category.
That's the extent of my knowledge, since I've personally never done this. Take a look at "entry point" in the MSDN.
Another approach is to create a dummy Console project and add MFC support to it. There you can get the code for initializing the MFC libraries. You can then create a regular "Win32 Application" and copy that code there.

Thank you Alvaro!
I've changed the type of linked application and included the _tmain() function and MFC initialization code from MFC library. It looks like this: <see below="">
Application starts normally, but it throws the access violation exception while destroying the application document. Wonder why.
Anyway I'll try to change the entry point from linker options.

Service.DisplayName = NETACCESS_DISPLAYNAME;
Service.Initialize(argc, argv);
RetCode = Service.Status.ExitCode;
}
// else
// WriteServiceLog(_T("Fatal Error: MFC initialization failed.\n"));
return RetCode;

if you switch from statically-linked MFC to dynamically-linked MFC, you'll see the difference MFC makes.
just using enough MFC to use CDialog and CString will add over to 200K to my ATL objects.

Generate a MAP file and then have a look at that. This list every function, class etc. and there address. So you can calc the size of functions as well if you want.

Hiya have just started to learn SQL and am having trouble with the INSERT and DELETE and EXECUTESQL statements. Can someone show me how to use these functions?? have tried but keep getting it wrong.
What I really need is a example program with some SQL statements being used.
I am using CDatabase and CRecordset for the database.
Thanks for your help.

hi,
CDatabase m_db; //declare database object
CRecordset m_EmpTable; // declare recordset for employee table
//////////////////////////////////////////////////////////////////////////////
// Open connection to database ORACLE01 (must be defined as
// data source in ODBC)
TRY{
m_db.OpenEx( "DSN=ORACLE01;UID=scott;PWD=tiger" , CDatabase::noOdbcDialog );
}
CATCH( CDBException, dbe ){
MessageBox( dbe->m_strError );
}
END_CATCH
//////////////////////////////////////////////////////////////////////////////
// Insert new employee record into table Emp
TRY{
m_db.ExecuteSQL( "INSERT INTO EMP VALUES(10, 'John','Brown','Chicago')" );
}
CATCH( CDBException, dbe ){
MessageBox( dbe->m_strError );
}
END_CATCH
//////////////////////////////////////////////////////////////////////////////
// Retrieve records from table Emp based on query
CString id;
CString fname;
CString lname;
CString city;
m_EmpTable.Open( CRecordset::dynaset, "SELECT * FROM EMP" ); // open recordset
while( !m_EmpTable.IsEOF( ) ) // retrieve records one by one
{
m_EmpTable.GetFieldValue( (int)0, id );
m_EmpTable.GetFieldValue( 1, fname);
m_EmpTable.GetFieldValue( 2, lname );
m_EmpTable.GetFieldValue( 3, city );
// do something with data
m_EmpTable.MoveNext(); // move to the next record
}
or you can do it like this..
CAccountRecord rs(&db);
rs.Open( CRecordset::snapshot );
rs.AddNew();
rs.m_NAME = "Becky Dugan";
rs.m_ADDRESS = "Bustins, ME 01443";
rs.m_ID = 33;
rs.m_AMOUNT = 100000;
if(!rs.Update( )){
cout << "Record not added; no field values were set.";
return FALSE;
}
rs.Close();
m_EmpTable.Close(); // close recordset
// How to do an UPDATE
/////////////////////////////////////////////////////////
rs.Open( CRecordset::snapshot,
_T( "select * from scott.account where id=42" ));
rs.MoveFirst();
rs.Edit();
rs.m_NAME = "Robert Dugan";
if(!rs.Update( )){
cout << "Update failed." << endl;
return FALSE;
}
rs.Close();
Verify that the update happened by using sqlplus:
// How to do a DELETE
////////////////////////////////////////////////////////
rs.Open( CRecordset::snapshot );
rs.MoveLast();
rs.Delete();
rs.Close();
i hope this is done now..Cheers

Hey all. I'm having some trouble figuring out askey. How would I cycle through a file to find out how many of each letter there is, and how many spaces, periods, etc. I know each letter has a number value, but how do I convert it? Also, how would I make a vector that has a slot for each letter in the alphabet increase by 1 every time a letter is found that corrosponds to that slot in the vector?
Hopefully you understood my question  .
Thanks in advance.

I haven't got a clue what "askey" is. My best guess it that you heard someone say it - in case it's spelled ASCII (American Standard Code for Information Interchange).
What you want to do is find the frequency of characters in a given file, and you are on the right track with the question:
how would I make a vector that has a slot for each letter in the alphabet increase by 1 every time a letter is found that corrosponds to that slot in the vector?
You first create a vector, or even an array since you know in advance that you'll only have to deal with at most 256 different values. Let's use the shortest code and use an array:
// The following line creates an array of 256
// unsigned integers, initializing all of them to zero.
unsigned int freq[256] = { 0 };
// 1.
// Here you are supposed to read through your file,
// one byte at a time, and put the read [unsigned char]
// value into a variable. Let's call it foo.
unsigned char foo = read_next_byte();
// 2.
// The following line uses the character value
// (if in a particular range also called the ASCII code)
// as an index into the array. Let's tell it we've found
// another character/byte with this value.
// Note that for a closed set like this (0-255), the
// index itself is actually also a data carrier.
// This can be worth recognising for further adventures
// into computing algorithms.
++freq[foo];
// Jump back to 1 until the file/stream is exhausted.
Now you can do whatever you like with your array.

I'm trying to figure out how to use a file passed or used to start my application when started by a file association through either double-clicking a data file or launched from an attachment from an email. The command line passes the pathname of the file that opened the app, however since the data file is locked I can not access the data through normal file opserations. Somehow the dataptr or filehandle is being passed or managed somewhere. Can someone explain how I can get access to that handle so I can read the data file?
In paticular I want to have access to the data from an email attachment. This means that the email app or some OS mech has launched my associated app and has the file locked.

I am not sure I understand your question but anything might help you.
1st try rebooting your machine. If you were debugging, windows might not be able to kill the process.
If you are looking at how to, launch your app when your file type is double clicked then you need to write to the registry on your setup script.

Surely you can open it read-only with read-sharing enabled? Else it would be, as you have recognized yourself, be an utterly useless mechanism. Since a multitude of programs apparently are able to do what you request, I must assume you have done something wrong. Play with the sharing flags and I'm sure you'll get something working.
Always request the least privilege you need to get the job done - this goes for everything, not just file sharing and the occasional write access.

I have a Windows Service application with 4-5 dialog boxes in it. I have good reasons to believe that it should have them, but the service would not start unless I remove them.
Anybody any ideas ?

If your running under the 'system' account you need to have "Allow service to interact with desktop" checked. This is in the Server Properties dialog that you must get to from the 'Services' control panel.

Yes that is check'd but is there any restrictions on the size of the UI resources that can be put in a Service (that is causing me problems) ?
or
Is there any limit on the size of the service exe image loaded ?
Tnx palbano

Thumb rule: Services should not have windows or consoles that provide feedback to the user.
If the service must have a user interface, it must run under the LocalSystem account.
Any information from EventLog when you have those dialog boxes?
