Visual C++ :: Writing To Named Pipe Coming From A Service (session 0) Without Admin Rights
Dec 9, 2014
I'm trying to write to a named pipe created by a service, as we all know the session 0 isolation implemented in vista and forward makes this task a bit complicated.
well at this point i managed to make almost all to work but my real problem comes when i try to write on the named pipe from my GUI application with no administrator rights
If i run the GUI application with admin rights it works 100% but, I don't need that application to require the user admin rights and for security reasons i rather to leave it without admin...
so i started my research and i found that there is a way to achieve this by calling CreateNamedPipe() with a low integrity security attributes...
well how to implement but i finally made it, the problem is that it gets worse than passing null security attributes, it works with admin rights with NULL security attributes, but when i pass the low integrity security attributes it gives "access denied" even when using admin rights, so i guess im passing the wrong security attributes but how to manually create the security descriptor string.
Im writing a scientific software where I like to sent a 2D array (5x4) over a named pipe from a server to a client. When im sending a static array (i.e., double res[5][4];), all goes fine and it works perfect, but when I allocate a dynamic array, it provides some nonsense numbers at the client side. I feel it might be caused because I point to a memory that cannot be shared through a pipe. Am I right and how can I pass the dynamic allocated array itself over the pipe.
//Server program
// Create a pipe to send/receive data HANDLE pipe = CreateNamedPipe( "\.pipemy_pipe", // name of the pipe PIPE_ACCESS_DUPLEX, // 2-way pipe -- send and read PIPE_TYPE_BYTE, // send data as a byte stream 1, // only allow 1 instance of this pipe 0, // no outbound buffer
I see there's something called a manifest file but VS C++ EXPRESS seems different than non-express. The solutions I've seen show applets/tabs that I don't have in Express.
In one of my physical DEBUG folders are some .manifest. files and some a .res and .rc file.
I know you need to edit the XML and change asInvoker to requiredAdministrator (or something like that).
The confusing part is if I go into Project Properties, MANIFEST TOOL caret/tree, under INPUT AND OUTPUT, it shows this .manifest file is OUTPUT. It's as if it rewrites it every time with some defaults? I have edited it, but I see it's back to asInvoker. There is a spot to put in a ADDITIONAL manifest file (or .res file).
Does a manifest somehow affect the physical .exe file (something is imbedded in it??)?
How do I change my project to make sure that the .exe always runs as Admin? Will doing this ALSO allow me to DEBUG it in VS C++ EXPRESS without having to do anything different (play with manifest or run VS outright with Admin level)?
I have an C++ application which uses Microsoft Web browser ActiveX control to launch any URL within the application. The browser is embedded in C++ form and It's working fine with all the feature Microsoft has exposed through Interface(IID_IWebBrowser2).But while any url that is using session cookie has been launched, even after closing the browser the session cookies are not getting deleted. For example if user login info is stored as session cookies,the url is using the cookies and getting launched without asking for user log in info.
But if I close the browser, and again relaunch , the cookies should be deleted and the url will not find the cookies to be used for log in . That is not happening here. Although this is session cookies , it's not getting deleted and being used by embedded browser. However, if the url is launched in IE, it is behaving as expected.
So, Do I need to delete the cookies explicitly? If Yes, How to do that?
I need to open up and modify a user's registry key from a 32-bit service (note that the user is not logged in at the time.) I do the following:
Code: //For simplicity error checks are not shown //I also made sure to enable the following privileges: // SE_RESTORE_NAME, SE_BACKUP_NAME
[Code]....
The problem is that the "SoftwareClassesLocal SettingsSoftwareMicrosoftWindowsCurrentVersionTrayNotify" key isn't loaded, even though I know that it exists in the actual user profile. I can verify that by loading the user account and by using 64-bit regedit.
I would need to know how to make the c++ builder application to be started with administrator rights (it's common behaviour for installers - when it is started, it asks for administrator rights).
I am working on a quadcoppter and am having trouble trying to parse the output that I am getting from the sensor. This is the code that I am trying to get to work but the Arduino compiler is saying that i can't convert and int to a string unfortunatley I am trying to get the string to convert to an int.
Code:
//string that will be processed is this //Ax=-209 Ay=5 Az=1116 | Gx=7 Gy=0 Gz=7 | -31 233 -433 Headings 100.20 void setup() {
How would you be able to show both outputs celsius and Fahrenheit and my temperature conversion is coming up wrong when i enter in the input. here is my code...
#include<iostream> using namespace std; int main(){ double celsius; double fahrenheit;
What I want to do is have an admin class which will hold all the employee objects, can add them, list and calculate salaries. I'm trying to make array of objects, not sure if it's right
here is the code
Code: #include <iostream> #include <string> using namespace std;
class Employee { public: Employee(string name, short type, int salary)
How to compare the username and password entered by user with the data(username and password saved in before) in the admin array and customer array,
so for example when it match the username and password in the admin array, it will directs the user to the admin_mainmenu(), otherwise it directs to the customer_mainmenu().
#include <iostream> #include <fstream> #include <string> using namespace std;

My 'c' program reads each line of a .txt file, makes a few changes and then outputs the line of text (which are names). I want the contents to be sorted and did not want to bother writing my own sort. The program runs in a command prompt from inside a batch file for example:
I have a problem with my simple operations calculator code (using C, in Code::Blocks). I am required to use a while loop statement so the user can execute multiple step operations without re-opening the program. When I launch the program, I get through the first session fine, but when I'm on the second session, when entering the two operands and press enter (to calculate), it just gives me the return and say press any key to continue (exit).Here is the code:
Code:
# include <stdio.h> int main() { int num1, num2; char op; int finished = 0; }
I use the following code segment to read and output the text piped to a program. If there is no piped text, the code segment is skipped and then the program continues. What I need to do is restore stdin to the keyboard after reading from the pipe. I use the PeekNamedPipe() and ReadFile() because reading from stdin blocks until it has something, and I don't want that to happen. After reading from the pipe, the program begins to execute, and the main loop can be paused and it prompts for a command. I just can't figure out how to restore input to the keyboard. Obviously the platform is Windows.
I have this if block that is supposed to be creating a pipe then forking and I would like to combine the while loop below it with it. How would I do that?
p = pipe(pipe1); if (p < 0) { printf("pipe error"); exit(0); } else { printf("successful pipe1 = %d",p);

I have trying to read this documentation but don't understand it. [URL] ....
I program a software to get scores from admin and sort them ascending then show the middle score(if admin enter middle).but when i compile it nothing happen.what should i do?here's code ,i use dev compiler
Code: #include <cstdlib> #include <iostream> #include <math.h> #include <string.h> using namespace std; int main(int argc, char *argv[]) { int counter,j,count,counter2,m;
I have study that create a pipe and set a terminal of this pipe like a stdout of a process is a way to implement inter process comunication, but how can i do it in c++?
