I have tried googling, so, reddit, irc, and various other forums. Anyways, I am writing a todo list app in c. It generates an xml tree that looks something like this: [URL]... . The problem where I am struggling, is in the function todo_complete, I try to make the attribute of an item switch from false to true. it does it without error, but I can't make it stay that way. here is the code: [URL]...
View 3 RepliesI have a char correctAns[100] which is empty when initialized. i want to make it hold a different string for each section, so i can use strcmp to compare the correctAns to the answer given by user. here is code

#include <string.h>
int main() {
char answer[100];
int checkAns;
char correctAns[100] , incorrectAns[100];

I would like to know how can i set a constant attribute in the constructor. This attribute is an int value that cannot be changed.
For instance:
class Test {
public:
const int x;
public:
Test(const int val);

With this code i get compile error!
I want to create a map contaning a regex as key and a char* as an attribute , like:-
map<regex, char*> res;
res["[[:alnum:]]"] = "alphanumeric text";
but the following error is generated:-
vector<pair<regex,string>>res;
res.push_back(make_pair("[[:alnum:]]","alphanumeric"));
but the error generated is:-
no instance of overloaded function "std::vector<_Ty, _Alloc>::push_back [with _Ty=std::pair<std::regex, std::string>, _Alloc=std::allocator<std::pair<std::regex, std::string>>]" matches the argument list
argument types are: (std::pair<const char *, const char *>)
object type is: std::vector<std::pair<std::regex, std::string>, std::allocator<std::pair<std::regex, std::string>>>

I have a input record like
acct|N|Y|N|N|rose@gmail.com
Now I need to create a logic to append a code to the end of the file using the following matrix rules.
00NNNN
01NNNY
02NNYN
03NNYY
04NYNN
05NYNY
06NYYN
07NYYY
[code].....
In the above example these four flags are "N|Y|N|N", so I need to append the matching code at the end of file "04".
desired output :
acct|N|Y|N|N|rose@gmail.com|04|
as it matches code '04':
04NYNN
I am trying to create a custom ValidationAttribute in my c# .net code. I have done a lot of searching and have code that should be working but the IsValid method is not firing as far as I can tell.
Model code:
[Required(AllowEmptyStrings = false, ErrorMessage = "required")]
//[Range(2014, 2100, ErrorMessage="Please enter a valid year.")]
//[RegularExpression(@"^d{4}$", ErrorMessage = "Please enter a valid year.")]
[ValidYear(ErrorMessage="Please enter one >= 2014")]
[Display(Name = "Exp. Year")]
public string expYear { get; set; }
And this is the class in that same model:
public class ValidYearAttribute : ValidationAttribute {
protected override ValidationResult IsValid(object value, ValidationContext validationContext){
return new ValidationResult("Something went wrong");
}
}
Why the IsValid is not firing.
I would like to modify attributes like modification/creation dates.The function is correctly working as if I type in "ls -al", the timestamp is correct. But when using my program to read these attributes, it returns the "real" modification/creation date. Here is the function that shows the timestamp :
Code:
time_t t = sb.st_mtime; struct tm tm = *localtime (&t);
char s[32];
strftime (s, sizeof s, "%d/%m/%Y %H:%M:%S", &tm);
printf ("%-14s %s", lecture->d_name, s); And here is the code for modifying the timestamps : Code: void modifyAttributes(char * file, int mtime, int atime)
}

I'm trying to edit an image by multiplying the red component of each pixel by 10 and leaving the other components (green and blue) untouched. I'm not really sure how I'm supposed to edit the pixels one by one. I have this so far. I think there is something wrong with my ppm header as well. Is there a way to make a ppm header without specifying the bounds so that it conforms to the image you are putting in?

#include <stdlib.h>

#define PICTURE_FILE 1
#define MIN_ARGS 2

Well,i hav a question requiring me to edit sales achieved by an employee for a particular month.
I'm having a dat.file which following format
Employee ID
Name
Sales(for a year)
For example
A00001
Harlem Shake
10.00 20.00 30.00 40.00 50.00 60.00 70.00 80.00 90.00 100.00 110.00 120.00
Wad I wanna is TO EDIT only the sales for July which is 70.00 to a new amount with other months remain intact.
I need to search particular id which will then link to their respective sales.
ofstream outFile;
string empID;
cout<<"Please Enter Employee ID:
[Code] ....
I tried to run myself before.But I could only create a new line instead of replacing.
To my understanding with ios::app ..will use the same file for editing..
Basically what I am looking for is a way to get a block memory, copy it into ram in a format along the line of bit[#], replace the original with a new code that may or may not be the same size(they will be something to ensure does not try to save a fraction of a byte).
Is there an easy way to do this or do I just need to read work from a bin file?
I have this function that takes the collision location from an object then creates a new object for particle effects.
This is one of the functions that is called when creating the particle,void Particles_Create(i32 iID, Vec3 &vecPos, i32 ProjectileType, i32 iNumberOfParticles, float fSpread, float fGrowSpeed, float fMaxSpeed, float fMaxSize, float fParticleTime);
I want to be able to change the "Vec3 &vecPos" variable, when I define the variable that goes into the function I've defined it as: "Vec3 vecPos;" if I define it as "Vec3 vecPos(float fvx,float fvy,float fvz);" the variable cant be fed into the function.
I cant change my function because its used elsewhere but I want to be able to change the x,y and z elements inside the Vec3 vecPos variable. How without redefining it as Vec3 vecPos(float fvx,float fvy,float fvz);
I have a button that opens a file dialog box so that a user can pick a file. I only need it for the path and file name to be passed to another program. I do not want to open the file or care about its contents. I just want the name and path.
private void button1_Click(object sender, EventArgs e)
{
OpenFileDialog dialog = new OpenFileDialog();
[Code].....
The problem is that as long as the program is running the file that the user picked is locked for editing. Adding the Dispose() had no affect. Multiselect and ReadOnlyChecked have no affect. Only closing the application frees the file.
I'm trying to create a program for my wife to be able to browser through and edit folders and specifically word documents- really just a shiny organization tool without having to open up Word. I'll be integrating other functions into this program but Word is what I'm worried about.
At the moment I've been able to create a file browser with the ability to add and remove files within the main directory of the program. Basically just C:Users\%user%mainDirdata*
Within the data folder I have the main folders which will be displayed as tabs across the top and then any subfolders of the main folders will be displayed on the left side after you click on the main tab.
[URL]
I'd need the toolbars to be integrated into the program across the top and then a window that changes depending on the document selected on the left side based on the content of the word document located in that folder. I haven't been able to find anything online and I'm not really able to spend $800 on the alternates that look like they just do automation as well.
I am trying to write a program that will read the id3v1 tag of an mp3 file, output the current information, and then allow the user to edit the ID3 tag. I can get it to output the information but I'm having some issues getting it to edit correctly. It seems to try to edit the wrong fields.

View 4 Replies View RelatedBasically I have an tile class with the following variables: x, y, texture, and solid. I have created an array called tile MAP[map_tiles_x][map_tiles_y]. The object of the following snip-it of code is to loop through all of the tiles in the map placing their default values in each. For some reason this code does not work as planned, but in theory shouldn't it? I cannot see why it doesn't work. (BTW I do plan on open sourcing this map editor.
void init_map(){
for (int tile_y; tile_y < map_tiles_y; tile_y++){
for (int tile_x; tile_x < map_tiles_x; tile_x++){
MAP[tile_x][tile_y].x = tile_x * tile_size;
MAP[tile_x][tile_y].y = tile_y * tile_size;
MAP[tile_x][tile_y].solid = false;
std::cout << MAP[tile_x][tile_y].x << ", " << MAP[tile_x][tile_y].y;
} }
I should also add the effect of the code. Basically it only sets the default coordinates for the first object :/.
I'm using windows forms and I have a parent dialog box that consists of a text box and a drop-down that launches a child dialog box. The child takes user input and then prints dialog to the text box in the parent. However, the output does not appear in the text box until I close the child.
Now my question is, how do I get the text to appear without closing the child? I hit a button to send the info to the text box, but it still doesn't appear until the child closes. I also need to set up a button to suspend the child so that the user can click/copy/etc the parent.

You are requested to create an inventory control application for a drink stall (give a name to the stall). The application is used to show the list of drinks the stall sells, how many of each item on‐hand and the cost of each item. The records are to be saved and retrieved to/from a binary file called “drinks.txt”. For each drink in the stall, your program is to keep the information as a Record Structure called DrinkRecord. The structure should at least consist of the following:
(1) Item Number
(2) Item Name
(3) Quantity
(4) Unit Price
Your application should have the following features:
(a) Display a drink information
(b) Add a new drink information
(c) Update a new drink information
(d) Delete a drink information
(e) Display all drink information

Everything works fine with minor issues, but I'm having trouble with the editing function. I need to be able to search for a specific drink then be able to edit its contents and print the new contents to the file. I have not created a structure yet. I will do that as soon as possible.

I'm attempting to save values from a char buffer into integer values of a struct.
This is what resides in the buffer "STD 2 2 2 2 2 2 2 " and this is my sscanf call
Code:
sscanf(buffer, "STD %d %d %d %d %d %d %d
", &dt_struct.date,
&dt_struct.mth,
&dt_struct.year,
&dt_struct.dow,
&dt_struct.hr,
&dt_struct.min,
&dt_struct.sec);
I then print the values back out in a string using sprintf.
Code:
sprintf(t_string, "STD %d %d %d %d %d %d %d
", dt_struct.date,
dt_struct.mth,
dt_struct.year,
dt_struct.dow,
dt_struct.hr,
dt_struct.min,
dt_struct.sec);
But this is what I get:
STD 0 0 2 0 0 0 2
Instead of what I want:
STD 2 2 2 2 2 2 2
I've been working on a homework assignment that randomly generates integers and populates them into an array (array1). The program is then supposed to:
1.) copy those values to a second empty array (array2)
2.) sort the values already in array1 (using an inline function)
3.) enqueue the unsorted integers from array2 into a heap vector
4.) a third empty array (array3) is supposed to be populated with those unsorted integers (by dequeuing them from the heap), sorted in reverse order.
But no matter what I do, I always get garbage values like these:
I've tried using both a standard random number generator:
array1[i] = rand()%100+1;
And the d_random.h file my instructor gave us, but nothing works.
Here's the code from all 3 files:
HeapTester.cpp
Code:
#include <iostream> // Provides cin, cout
#include <cstdlib> // Provides EXIT_SUCCESS, rand, srand
#include "d_random.h"//Provides random number generator
#include "Heap.h"
using namespace std; // Use C++ Standard namespace
//Elements in each array.
const int arrayLength = 15;//100;
[Code] ....
Why I'm getting those garbage values?
I was wondering if this was even possible and if so, how do I do it.
else if (speech.ToLower().Contains("truck") && speech.EndsWith(number))
{
Here I would like to see if my speech had ended with any of the values i would have stored in the string "numbers". If it did, I would like to just take the value and add it to a new string called whatever
}
I have tried this a million different ways and I cant get it to work. I'm not even sure how I would go about storing tons of different numbers in one string, or if that's even possible.
