I am having a lot of trouble trying to save and upload a data table from a text file ,the data table which is bound to a datagrid, creates its own columns at the formloading event, and everytime a user clicks a button row is added to the data table. With the loading i put this code which i thought would read a text file and put all the content my datatable however a exception pops up saying Duplicate Name exeption. Heres the loading piece of code :
{ string filePath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop) + "\DG1.txt "; if(File.Exists(filePath)) { StreamReader reader = new StreamReader(filePath); string line = reader.ReadLine();
So I am awful when having to use data or .txt files. I believe my code is right, I just don't know how to upload the files. Here is the description of the assignment and the coding:
Process the input file containing latitude and longitude data of US cities in degree, minutes, and seconds. Output the processed information in decimal degrees.
a) Write a C++ program to read each line of the input file, store each data line in an array of structure, calculate the degrees in decimal for latitude and longitude, store these values in the corresponding structure and write the results to the output file by processing the array.
b) Use vectors or dynamic array to optimize memory usage. Specify the design choice in your main comment for the program.
c) Split the City and State and store it in two separate fields.
d) Search a city and find it in the array of structure and print out ALL the information on the screen.
#include <fstream> #include <iostream> #include <iomanip> #include <vector> #include <string> #include <algorithm> using namespace std; struct City
I managed to upload a file to a remote server with below code:
Code: // Get the object used to communicate with the server. FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://kasunl.worlditsme.com/voo.txt"); request.Method = WebRequestMethods.Ftp.UploadFile;
I'm trying to upload a file to a FTP server with curl. The problem is that I do not know what to do after I enter the passive mode and open the specified port. I tried to send data with curl_easy_send but it simply hangs.
bool Ftp::Upload(const char *local_fn,const char *remote_fn) { int ret; string ip; unsigned port; SendCmd("TYPE I"); // Enter passive mode and get IP & port if(pasv(ip,port)==false) return false;
[Code]...
How to send file to the server. And I also suspect I should tell the file size to the server.
Basicly I want to make a c++ program which does the following:
1- logs in to 4shared.com with username 'user_example' and password 'password_example'. 2- uploads to the 4shared account a file named 'test_upload.txt' located in 'C: est' 3- downloads a file named 'test_download.txt' from the 4sared account
I user curl 7.39.0 and curlpp 0.7.3
1- how to keep the same session between successive http requests 2- how to make an http request to upload a file 3- how to get the url of a file with specified name on a 4shared account
I develop a software using QT 5 open source IDE. Now my question is two-fold:
1. How can I create the final executable file that I can upload for my users? I understand that runtime DLLs shall be required and I have tried Enigma Virtual Box software for bundling runtime files. It does create the file that I can execute from any folder in my PC. However, surprisingly when I transfer that "boxed" file to another PC, it does not run. Both the PCs have Windows 7 installed on them.
2. Secondly, I see possible future issues with Antivirus Softwares. Apparently when I try to run the boxed exe file, it gets rejected by the Antivirus Software on my PC. Is there a way in which I can get my exe file verified/checked/registered by the Antivirus Softwares so that my users don't face any problems in executing the program.
I cannot afford the QT commercial licence, but I am prepared to buy any economical "setup file generating" software (if it exists).
I have an application which is used for calibration for electrical components. Here I want to set a rootpath for this application. I did some research and I found out that I can get the rootpath of the application (that is where the exe is stored) But what I am really looking for is once I start the application the root path should be what I assign. For instance currently the root path is "C:UsersPublicDocumentsABC.ToolsProjects" but I would like the root path to be "E:New ABC" Is this possible? I wrote some code where I call the exe of the application and it opens the file in a folder that I specify :
// Make sure there are no errors hIConnect = InternetConnect(hInternet,"192.168.1.4", 211, "******", "*****", INTERNET_SERVICE_FTP, INTERNET_FLAG_PASSIVE, 0);
i have to upload a ms access database file to the server from my client program. The server program should connect to this database and read the data. What's the easiest way to upload the file? Is it FTP? i tried sockets, but it only allows like 9kb of data transfer capacity.
Using C . I have been tasked (for a University assignment) to create a program that will enable a user to upload an image and convert that image into ASCII text using SDL on a Linux system. I've managed to open a window, display an image (non-selected) and convert it into grayscale using
case SDLK_g: for (int y = 0; y < image->h; y++) { for (int x = 0; x < image->w; x++) { Uint32 pixel = pixels[y * image->w + x]; Uint8 r = pixel >> 16 & 0xFF; Uint8 g = pixel >> 8 & 0xFF; Uint8 b = pixel & 0xFF; Uint8 v = (0.212671*r)+(0.715160*g)+(0.072169*B)/>; pixel = (0xFF << 24) | (v << 16) | (v << 8) | v; pixels[y * image->w + x] = pixel;
I am absolutely clueless as to how I can get the user to upload an image to the program and then begin the image -> ASCII conversion. I've found seem to be written in C++ or C# to make the conversion I should be using the GetPixelColour command?
I am writing a program where I need to read a byte of char data and convert it into a text string of binary data that represents the hex value...
i.e. The char byte is 0x42 so I need a string that has 01000010 in it. I've written the following subroutine....
------------- My Subroutine ---------------------------------------------------------------------- void charbytetostring(char input, char *output){ int i, remainder; char BASE=0x2; int DIGITS=8; char digitsArray[3] = "01";
[Code] ....
When I submitted the byte 0x42 to the subroutine, the subroutine returned to the output variable 01000010... Life is good.
The next byte that came in was 0x91. When I submit this to the subroutine I get garbage out.
I am using a debugger and stepped through the subroutine a line at a time. When I feed it 0x42 I get what I expect for all variables at all points in the execution.
When I submit 0x91 When the line remainder = input % BASE; gets executed the remainder variable gets set to 0xFFFF (I expected 1). Also, when the next line gets executed..
input = input / BASE; I get C9 where I expected to get 48.
My question is, are there data limits on what can be used with the mod (%) operator? Or am I doing something more fundamentally incorrect?
I have written the following code to add data to text files which are required to store 3D scan data (I have to calculate the y-coordinate). My code seems to work except that it stops working when I want to create more than ten text files i.e. the directory I am trying to store them in will not hold any more than ten text files. Code is shown below.
#include <iostream> #include <fstream> using namespace std; int main() { int r = 0; int c = 0; int num[17][15] = { 0 }; [Code] ...
// Here is my code for displaying the data from the text file into a 2d array and height next to it, but I am not able to diaplay the height from 60 to 76 next to the row of the 2d array, as shown in the table below. This is my program:
Recently the health authorities have listed a new way to calculate the body mass index (BMI) of an individual. Values of 20 – 24 are classified as normal, 25-29 as overweight, and 30-34 as heavy.
The table below is a portion of a typical BMI table.
Been trying to configure the GridView to display ony 4 rows of data at a time. I thought it wasn't working because I forgot to set AllowPaging to True, but after I did that, I just get the error of
The data source does not support server-side data paging.
Source Error: Line 66: titlesGridView.DataBind(); // displays query results
Here is my Books.aspx.cs code:
// Fig. 29.11: Books.aspx.cs // Code-behind file for the password-protected Books page. using System; using System.Data.Entity; using System.Linq; namespace Bug2Bug.ProtectedContent { public partial class Books : System.Web.UI.Page {
[Code] ....
Am I missing anything or doing something wrong thats not causing it to page & only display 4 titles at a time?
I have a situation where I am accessing an ASP.NET Generic Handler to load data using JQuery. But since data loaded from Javascript is not visible to the search engine crawlers, I decided to load data from C# and then cache it for JQuery. My handler contains a lot of logic that I don't want to apply again on code behind. Here is my Handler code:
public void ProcessRequest(HttpContext context) { JavascriptSerializer jsonSerializer = new JavascriptSerializer(); string jsonString = string.Empty; context.Request.InputStream.Position = 0; using (var inputStream = new System.IO.StreamReader(context.Request.InputStream))
[Code] ....
I can call the function : getUserControlMarkup() from C# but I will have to apply some URL based conditions while calling it. The contentType.typeOfContent is actually based on URL parameters.
If possible to send JSON data to this handler then how to do that. I am trying to access the handler like this:
Since the calculation I performed gives me -71.77 Volts, I need to match this value to the time that this occurs closest to using my program, and output the time that this occurs at.
Here is my program so far: int main() { std::ifstream inFile; inFile.open("AP.txt"); ofstream results_file ("maxvaluewithinput.txt"); float TimeAtdVMax = 0; float VoltsAtdVmax = 0;

If you're curious, this program isn't for homework. It's part of the independent learning on C++ I'm doing for a Master's Thesis; the program will eventually model the APD90 of a ventricular action potential.
I am wanting to be able to add as many different instances of data, while the user has not stated 'n', but then it only ever writes back to the screen the input for the last set of data. Where as I want to display back to the screen all the data that has been entered.
