I figured it out when I built a simple demo project. Problem arose because of trying to access a c-wrapper dll from the app class whereas the wrapper class had not been initialized there but rather in the main dialog class - so naturally it didn't work!!! Anyway, I've attached the demo for any who might be interested, but I regard the problem as resolved. Shows the value of building simple projects to isolate a problem. I failed to organize the order in which such a program initializes - I guess it's always App first, then MainFrame, then Doc and View (I think).
I'm new to C and encountered a weird problem. Here's the code:
int main(){ char name[]=""; readname(name) ; printf("The filename is: %s ",name); printf(name);
[Code] ....
I compile this with no problem, but gives "File could not be opened". the strcmp tells me name and "snazzyjazz.txt" are not equal. but when I print them I get the same output.
So. I have a CSV Parser that I built. It works very well. The way it currently works is that I have the parser in a header file "CSV_Parser". So my .cpp code would look like this:
#include <iostream> #include <eigen3/Eigen/Dense> #include "CSV_Parser.h" using namespace std; using Eigen;
[Code] ....
This all works great. I am running Eclipse in Linux (Xubuntu to be precise). In the header file the .csv is opened as follows:
What I would like is for the user to be able to change the file that the parser is opening through the main .cpp file. In other words, is there a way to create some variable, say "FileName" and do the following:
I am trying to establish a connection between client and server to send a file to the server from a client. I have been successfully able to send files to the server but i am facing a problem with the the filename whenever i try to send any string to the server and use it in naming the filename at the server side, the string is successfully concatenated but it saves the filecontents in the filename.
for example: i am sending a file hello1.txt to server and the server has to save it as abcxyz.txt as i am sending the "xyz" from the client. BUT Whenever i am doing this ,the file saves as abcxyzfilecontents.txt If i saved in the .txt file "you123" ,my file at server side would save as abcxyzyou123.txt
Here are my codes:
Know that the server code implements a multi threaded server. The functionality to be discussed is defined in myfunc
I am wanting to have a text file which is named with the user input and appended with .txt.
cout << "Please enter a new filename for storing new coordinates in: "; char name[50]; ofstream output; cin.getline(name, 50); output.open(name + ".txt");
I have written some c++ code in codeblocks but I am getting errors when i am trying to compile it. I have a file named files.txt and this file consists of the names of the files that actually contain the data that I need to present. I am trying to get the name of files from from once class and passing it through to another to process. These are the codes that i have:
main.cpp #include <iostream> #include <fstream> #include <string> #include "Files.h" #include "Datafile.h" using namespace std; int main() { ifstream infile("fileListAug.txt");
[Code] .....
The error message that i get is error: no match for call to (std:: string). For ther line with the error I have used (*******Error points to this line).
