C# :: Writing To Text File And Uploading It To Server Directory
Dec 25, 2014
I want to write a single line to a file and upload it as a .txt file to a server directory . I know the traditional way to upload a local file to a server
I'm having a little problem with std:fstream - in my program, the user selects the location of a file which I want to remember. So, I have something like this:
Code: std::string fileLocation; //Code here creates an 'open file' dialog box which lets the user choose which file to open. //The string 'fileLocation' now contains the path to the chosen file. std::ofstream prefs("prefs.txt"); if (prefs.is_open()) { prefs << fileLocation; prefs.close(); }
This works fine if the file chosen is in the same directory as the program, however, if they try to choose a directory outside of where the program is kept, it saves the text file into that directory instead of the same one as the program. So, it looks like outputting a directory into an ofstream actually changes the location to which the file is saved.
Is there a way to save the file directory to a text file using ofstream and still have the text file save in the same directory as the program?
I'm reading from stdin a line. With that line, I should open a new textfile with the first letter of that line on a certain directory. My code is the following :
Code:
int main() { char line[BUFSIZ]; FILE *ptr_file; int x; while(fgets(line,BUFSIZ,stdin) != NULL){
[Code] ....
char caminho[] is the directory in which I want to create the text file and chave will be the first letter of the line in stdin.
How am I supposed to use strcat to get these two together in a string to then use ptr_file =fopen(caminho, "w");
I am writing a simple file/text parser to read a config file for some code I am working on. It's dead simple and not particularly smart but it should get the job done. The code reads a config file:
Here is where it gets wierd. You'll notice that there is an unused variable (filepath) in the config struct. This variable is not referenced or used anywhere in the code, ever. Yet if I comment out the declaration of char filepath[1024], the code segfaults partway through the read_config() function.
My best guess is that there is a buffer overflow elsewhere and it just so happens that the memory allocated for filepath happened to be there to catch it up until now, but I can't work out where it might be happening. With the declaration commented out, the read_config() function gets as far as reading the "padding" variable before it crashes. Yet when the declaration is there, then all the variabled are read correctly and everything seems to work.
Code to write data(Double type e.g 12345.67891) in text file like pattern given below. Remember to put tab between each column.

[URL] when I try to write my output to a file. I am building a life insurance premium calculator with c++. What my calculator does is read in a text file called "policies.txt" containing a number of different policies. For example:
Pol1 M N 20 100000 1 .04 99 Pol2 F S 30 100000 1 .05 99 Pol3 M S 72 750000 1 .03 99 Pol4 F N 45 1000000 1 .05 99
And using this, it creates a single premium. Once the calculator calculates the premium of each policy, I want it to write out the premium amount of each policy to a textfile called "output.txt". The problem is that when I check my "output.txt" file, only the premium for the last policy shows up. It only reads:
Premium for Pol4 is 220384 When I want it to read:
Premium for Pol1 is 14101.6 Premium for Pol2 is 14221.2 Premium for Pol3 is 582391 Premium for Pol4 is 220384
How come only the last policy is showing up? and is there any way to make all four policies appear in my output text file? Here is my code:
My program involves trajectory planning using cubic spline method for a robotic arm. In the process, I had to calculate joint angles for each point in the path. In the last few lines of the code I need to write the values for counter and theta1 into a text file which I called "Test.txt". I am doing this using a nested for loop(the counter runs until it reaches 19 and hence need 19 theta1 values corresponding to it). However, I can't get all the theta1 values transferred to the text file.The statement within my inner loop is wrong and don't know how to fix it.
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'm trying to make a program that you input your login info and it writes that info to a text file. Then, later on once I get my problem fixed, the program will read the info to the user. my code is as follows(the input part is a bit lengthy):
I wrote a program to write text contents to file stream through fputs, the file stream address was changed in the middle of writing text content to the stream (11% text content have been put into the file stream), that cause the file stream pointer can be evaluated problem and raise exception on stream validation code in fputs library function, my question is what things could go wrong to make file stream pointer changed its address to something else or a NULL pointer if the file stream have not been flushed and closed.
I'm trying to get a Browse Directory dialog to update a text box with the path selected. I had it working fine in Unicode build but now using TCHAR - I see the variable contains the correct path, but the textbox only gets updated with a single weird character.
I understand I can do this via a php file on a server, but I don't understand how I can communicate with the php file from c++ code on my machine. Is there some library function I can use to load the html form or data object to hold the php form? Also whats the vibe on amazon EC2 cloud computing servers? It may be out of the scope of this simple program I have uploading and downloading XML, but is this the technology of the future, and should it be embraced now?
I want to open a command prompt from a console application in a separate window and write some lines of text in the new command prompt.
In the Below code it is not opening the new cmd and not writing the text...
Here is the code: public static int Main(string[] args) { int retValue = 0; try { ProcessStartInfo MyProcess = new ProcessStartInfo(); MyProcess.FileName = "cmd.exe";
I need my Unix program to generate a directory with a format like this: "hinesro.<pid>". I have some code that mostly works, except for the directory ends up with a question mark on the end, like this: "hinesro.12345?". I need it to just display the directory without this question mark. Here is my code:
Code:
// Using headers sys/types.h, sys/stat.h, unistd.h, and stdio.h int pid = getpid(); char prefix[] = "hinesro."; char fileName[0]; sprintf(fileName, "%s%d ", prefix, pid);
