I am starting a project in a few weeks that needs to be able to prevent an executable from running until it has been checked for various criteria (think of it as a DIY anti virus).
My main idea is to build a file filter driver in C to hook into file system reads and writes and prevent executables that I don't like from executing off the disk.
How to get this code to compile and build. It gives me a really strange error saying:
"1>Project 7 Code.obj : error LNK2019: unresolved external symbol "void __cdecl checkAnswers(char * const,char * const,int,int)" (?checkAnswers@@YAXQAD0HH@Z) referenced in function _main
1>C:UsersHaruha Raharu HarukoDesktopSpring 2015 Class WorkIntro to ProgrammingProject 7Project 7DebugProject 7.exe : fatal error LNK1120: 1 unresolved externals"
Here is the specifics on the assignment:
"Complete Programming Challenge #12 (Driver's License Exam) with file modification
The State Department of Motor Vehicles (DMV) has asked you to write a program that grades the written portion of the driver's license exam, which has 20 multiple choice questions.
Here are the correct answers:
1. B 5. C 9. C 13. D 17. C
2. D 6. A 10. D 14. A 18. B
3. A 7. B 11. B 15. D 19. D
4. A 8. A 12. C 16. C 20. A
Create a TestGrader class. The class will have an answers array of 20 characters, which holds the correct test answers. It will also have a student array of 20 characters to hold the student's answers. It will have three public member functions that enable user programs to interact with the class: setKey, setStudent, and grade. The setkey function receives a 20-character string holding the correct answers and copies this information into the answers array. The setStudent function will read in the student's answers from the file student.txt and will store the answers in a 20-character array named student. The grade method will compare each student answer to the correct answer in the key.
An applicant must correctly answer 15 or more of the 20 questions to pass the exam. After grading the exam, the program should display the following items:
-the number of right answers and the number of wrong answers
-a list of the question numbers for all incorrectly answered questions
-a message indicating whether the applicant passed or failed the exam"

View 2 Replies View RelatedRecently I got a drawing tablet. One valued feature of this tablet is that it is pressure sensitive (2048 levels). No matter what the model, almost every company's tablet's features (like pressure) are compatible with well-known commercial products like Photoshop, and this is precisely what I'm wondering about:
If well-known graphic products can do it, how do I make my own program to recognize this device's features? How can I access/extract real-time data from a device. Assuming I have all driver stuff correctly installed.
I've been trying to google keywords like "[company] header files" or "[company] developing programs" or stuff like that to no avail... not really sure what to search for.
If you need specific information about the actual device, I will post it, but I'm also just looking for general knowledge about how to this type of thing, with any device.
(I'm not talking about a GUI or how to actually code graphics to respond to the pressure, just about receiving information from it.)

I'm new to c# and i'm using vs 2013 and access database..my i need to do multiple update records after I filtered the records in datagridview
In my database table I have these fields ID(PK/autonumber), EID,Date,Day,Daystatus..
In my form I have a button and it's fucntion is filter by date using bidingsource.fiter and this was the result
EID------Date-----------Day---Daystatus
10175--10/11/2014---sat--------regular
10176--10/11/2014---sat--------regular
10177--10/11/2014---sat--------regular
10178--10/11/2014---sat--------regular
what I want to happen is when I click another button called "Apply to all" I want to Update all the daystatus to "Legal Holiday" of the filtered records..I know how to update one by one using simple update..but I need to do the multiple update..
I tried to make a code but it was updating all the records not the filtered only here's my code:
try {
OleDbCommand command = new OleDbCommand();
connection.Open();
command.Connection = connection;
string query = "SELECT EID From EmployeeTable";
command.CommandText = query;
String a = "Legal Holiday";

I am trying to apply gabor filter to a fingerprint for fingerprint enhancement using c.
My image size is 280x340.Gabor filter equation is :
F(x,y) = exp(-0.5*[x^2/sigma_x^2 + y^2/sigma_y^2]) * cos(2*PI*f*x);
I am able to execute this equation.But my problem is i am calculating the equation for 280x340 times and it is taking time(4 sec 2.93GHz 3GB ram).
how to reduce the executation time ?
What I know exp function is taking time. So is there any equivalent of exp which will take less time to execute ?
I'm trying to get some more user friendly things in my program done. Now I'm trying to filter by typing in a text box and it filters to what you are typing and shows the entire row.
This is what I currently have:
private void txtFilter_TextChanged(object sender, EventArgs e) {
try {
SQLiteConnection connect = new SQLiteConnection(connString);
connect.Open();
[Code] ....
I get an exception error though:
SQLite error
near "'N'": syntax error
// N is what I started typing to start the filter.
Ok, so I've edited the code now to this:
private void txtFilter_TextChanged(object sender, EventArgs e) // FILTER TODO {
DataView view = new DataView();
SQLiteConnection connect = new SQLiteConnection(connString);
connect.Open();
view.RowFilter = "Channel like '%" + txtFilter.Text + "%'";
}
No more exception errors, just not what I want it to do. It just keeps everything there.

I probably write it wrong, but I can't remember the correct way. In examples I only see that instead of -> dot is used, but it doesn't work either.

I need to be able to actually read my encrypted file..
I have the decryption code and works perfectly when running it through console app c++.
But, the way I decrypt is to decrypt from a file, and create a new file which is decrypted.
I can't use that kind of code in my program in windows form app c++..
I need to read the encrypted text file and decrypt it in memory while using it for my program..
Some links to my codes I use at the moment.

I have a problem with an extension DLL that has an exported function. The function is being exported ok, it is called by a Windows service. The Windows service is using the exported function, and everything works. I am trying to create a file with:
ofstream file;
file.open("C:dir ofile", ios:ut);
file << "text";
But nothing happnes however. There are no errors, the file is just not created. Also, if i try to call MessageBox() in the exported function, nothing happens as well . I have a .h file which exports the function with __declspec(dllexport) DWORD WINAPI functionName(), and also a .cpp file with the function definition. There is no main().

It just seems to me theres a lot of conflicting information about if this is even possible to do on Windows and when I do try work around functions or calling double drand(void) I get a ton of errors. I'm hesitant to try rand() or something less precise. I was hoping maybe someone would be able to maybe suggest a compiler which will run this or a different library, right now I'm using Code Blocks IDE.
