I am trying to create "dummy" drivers for testing purposes of another program of mine.
I want to be able to Call DeviceIoControl and pass a string in as the buffer and then receive that string in the driver, change it and return it. But right now I am not able to receive the string, when i get the buffer and print it out it is garbage. Where am I going wrong?
I sent 1preample and 4bytes in transmitting side , preample contains only 1 and 0 with 4milliseconds delay, each byte contains 8bits with 2milliseconds delay , if a bit contains 1 it will send 1millisecond high and 1millisecond low signal ,and if a bit contains 0 it will send 2millisecond continuous delay, I have a problem at receiving side how to capture and store the preample and 4byte values in a buffer , i am using ARM processor it will update every 5microsecond ..
I have a problem with my C#. Trying to create the airstrip with planes heading out of the hangars and on to the road to the airstrip. Each Hangar pannel is connected with closes road to them. What i am stuck with right now is connecting the roads together so each one of them will see if the next road is free and if it is it will send the plane (colorder square for now) to it and then proceed to the next one when finaly they will line up for the final panel(airstrip) and take off.So far they are just going down the each road they are assigned with semaphore and thread.
using System; using System.Windows.Forms; using System.Threading; using System.ComponentModel; using System.Collections; using System.Data; using System.Drawing;
[Code] ....
Connecting the "p2" with "p5" so the graphics from "p1" the square will travel through P2 and P5 this would be great and will allow me to procede with my studies.
Also i do realise that this might not be the best ways of using concurrent Csharp and not the up to date one but this is what i have been assigned with and do not have any other options unfortunately.
How i understand this is that i need to have 3 buffers and 3 semaphores for each panel. But i do not know how to add those to each one of them and then connect it with the next one as if i try and add them it either puts a cross in the design view over that panel or says that there is limited options for this statement.
This is the way that i want to do it unfortunately it must be so. The most flexible this can be is by adding an array for semaphores and buffer ( do not know how to do that either).
For this problem, you will design and implement 2 classes and then write a driver function to test these classes. The first will be a C++ class for an abstract data type color with a public enumeration type colorType that has the color values shown in Listing 10.8. Your abstract data type should have an attribute for storing a single value of type colortype and member functions for reading (readColor) and writing (writeColor) a color value as well as setting and accessing it. The function readColor should read a color as a string and store the corresponding color value in the value attribute of a type color object. The function writeColor should display as a string the value stored in the value attribute of a type color object (see Figure 7.5). Modify class circle and the driver function in Listing 10.9 to include and use this class. You'll need to remove the declaration for color in class circle. Test your modified driver function with the new color and circle classes.
The second class will be to design and implement a rectangle class similar to class circle. Be sure to incorporate the new color class you have written and tested in the first part of the programming exercise. Write a client program that asks the user to enter a shape name (circle or rectangle) and then asks the user for the necessary data for an object of that class. The program should create the object and display all its attributes.
The circle class .h and .cpp files as well as the original driver function will be supplied. You are to provide the .h and .cpp files for the new color class and the modified driver function as well as the .h and .cpp files for the rectangle class and the client program that uses all three classes.
What I have so far, and I'm pretty lost;
color.h
Code:
Code: //color.h //Color class definition #include "stdafx.h" #ifndef COLOR_H #define COLOR_H class color { public: enum colorType {black, blue, green, cyan, red, magenta, brown, lightgray, nocolor};
I am having difficulty calling the constructor in interface portion of my program. I get the error: no matching function for call to ‘Node::Node(int, NULL)’ when I try to call it on line 26 within the main function.
code: interface: [URL] implementation: [URL] main file: [URL]
I am getting "driver could not be loaded due to system error 8" error while connecting to SQL Server 2005 from VC++. Its also throwing out of memory error. Basically i am developing and ISAPI dll. I use the following code to connect to DB.
I'm am having a few issues with this program, they stem from passing the color.h and .cpp into another .h and .cpp, and frankly getting how those two things really fit together.

i want to write a c++ program that could pass a web page request, using a php script in a dns server. And also passed by the quested page to the software. What i really want to do is a software that can redirect a page request.
Here is the site that I want to interact Genderchecker
I want to set a value to a specific element in a web site. Perform a click on an element that is image. Get the result <span> text into string variable...
I'm writing a small c++ program which will be able to do a few things with a matrix. I have a class called Matrix and a member function in it called getSor() which returns an integer value about the number of lines in the matrix. When I call this getSor() function the program says: error: request for member ‘getSor’ in ‘matrix’, which is of non-class type ‘Matrix*’
- 'matrix' is an existing Matrix object here - I called the function like this: "cout << matrix.getSor() << endl;"
how do i send post with data to a php page on the net using c++? im using this for a file uploading site for my school group. and also, im planning to pass this as my project. but, i cant find a concrete way on how to send post method with data to a php page. ive been fed up with a lot of answers from the net, yet, each time i try to use them, i get errors. ive tried every library you can see till the third o of google. ive also tried a wrapper from this site, but, ive got no succes. im using dev c++.
I want to know how to respond to a request made by a mobile application (preferably Android) through a desktop software. So for example if there is a button on the mobile app named 'do something and a user clicks it, I want the desktop software to respond to that request and 'do something
So what I was thinking was to upload a file to a server when the button on the app is clicked and add a timer to the desktop software to connect to the server and read the file and respond accordingly.
Is this how it is usually done or am I going about this the wrong way? Im developing the app in C# (Xamarin) and the desktop software in C# as well.
I have problems relating the HTTP server request line validation into a c++ code, where the request line is defined as follows:
method SP request-target SP HTTP-version CRLF
and the server supports absolute-path [ "?" query ]
At the same time absolute-path must start with / and might optionally be followed by a ? followed by a query, which may not contain ".
Basically, method must be GET, request-line must begin with / , request-target cannot contain " ,HTTP version must be 1.1 (HTTP/1.1), and the absolute-path must contain the character .
I want to write a little c++ program that sends a request to a server an get some data. I found the C++ Rest-SDK and decided to use it. I searched on different websites for code-examples but many of them doesn't work an shows syntax errors. What i got now is that code but the client.request method is skipped. The program never jumps in.
Now, i know the general idea of how its supposed to be done but I just cant get it right. Either my "post" message is wrong all the time or some library is not working properly. Im not even including the code for the application because I have 5 projects, each with different approach and none of them is working.
Ok, so the assignment is to use a recursive function to display a request for a certain position in the Fibonacci Sequence (0, 1, 1, 2, 3, 5, 8, 13...)
The program I have written works, but it displays the wrong number in sequence. The book says that when you enter "8" you should receive "13", which is correct in the order of the sequence, though my program is producing "21" which is the next number in the sequence.
I tested it with a few more numbers and when I enter "7" it produces "13" and when I enter "6" it produces "8" and so on.
