C# :: Renaming And Deleting Controls (2012)
Aug 16, 2014If I rename a control, when I build, I get an error because deep in the code, the old name exists, but my rename doesn't change the old name. Am I doing rename wrong? (I just go to "Name" in properties and type the new name.)
Same idea with control deleting. So I add a control (textBox, label, whatever). I later decide to delete the control. When building, it still has code for the old control and won't let me proceed.
C/C++ :: File Renaming / Permission Denied
Oct 9, 2012I am writing a C++ program that finds the Word Documents on your computer that have '+' or "%2B" in the name and replacing those '+' and "%2B" with ' '. I am writing this program for my school's University Writing Center, so I predict the only places they will have these files are the USB memory stick, Desktop, Documents, and Downloads. I encounter a problem, however, when I run this program and it renames the files in Downloads: Permission denied. I am using the windows.h to do this. How do I give the program permissions to that folder?
update:This program is going to be written in C++.
C++ :: Debug Error When Deleting Dynamic Array
Feb 18, 2013I get this error when I'm attempting to delete an array. I'm new to dynamic arrays, and from what I have learned, arrays must be deleted after use. I plan on using this in a function later on, so deleting the array is a must.
Here's the error message: Debug Error!
HEAP CORRUPTION DETECTED: after Normal block (#154) at 0x007E55A0.
CRT detected that the application wrote to memory after the end of heap buffer.
Here's my code:
int main() {

int* primes = NULL;
int size2 = 0;

C++ :: Unicode Support For Windows Renaming API?

C++ :: Deleting Certain Bytes From Binary File?
May 26, 2013How to delete certain bytes from middle of a binary file?
Those bytes are in fact of a struct.
One approach I found was to re-write the whole data except the struct I want to delete. But may be its not good one if file size is in gb and I will have to write complete data again.
C :: Reading Matching Strings From A File And Deleting From Another
Sep 26, 2014We are generating emails for freshman students, however, the system probably due to server overload fails to generate some emails. So I'm working on this c code( probably was a wrong choice) to search for regexp matching the generated emails and deleting from the list of students and propective emails.
I"m currently at the stage of making sure the code can find all the matching regexp from the student list file before deleting! But the code fails to read all matching regexp?
Code:
//Filename: SearchReplace.c
//Usage: This searches for lines in a file containing a particular work and deletes the lines.
//Licence: GNU P.L.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>

What I'm missing. It recognizes some regexp and fails to recognise some. Been staring for hours!
C++ :: Deleting Repeated Lines In A Text File
Jul 30, 2014I have a text file with repeated lines, and i would like to get rid of the duplicate information, an algorithm to achieve this?
Example of my text file (the actual file may be huge, up to 500MB):
+Hello
+Bye
*The sun
-The moon
+Bye
/One coin
+Bye
+Bye
+Hello
*The sun
And i would expect to get something like this:
+Hello
+Bye
*The sun
-The moon
/One coin
I know how to open and read a file with fstream and getline(), but i don't know how to make the comparison.
C :: Array Of Structs (adding / Deleting Elements To A File)
Sep 20, 2013I want to write a program to record my neighborhoods's name and address by using an array of structs and file.
my array of structs is
Code:
#define SIZE 30
typedef struct{
char name[30];
char address[100];
}Detail;
Detail neighbor[SIZE];
And I want to make adding,deleting, and searching functions.Something like
Code:
void add();//Add name and address to a file,
//and add more to the same file if I want to.
void del();//Delete or Change some neighbor's name or address
//in the same file(Can I?)
void search();//Search name and show detail
So I started to code adding function first, but I don't know that I need to use pointer to code each functions relations, and I don't know how to check that my input's already exists yet. But I started some code below...
Code:
void add() {
int i=0;
FILE *fp = fopen("neighborhood.txt", "at");
if ( fp != NULL ) {

C# :: Mapped Network Drive - Deleting Or Moving A File
Sep 16, 2014Currently I'm trying to do something extremely basic: delete or move a file
I have a mapped network drive (Y) where I have a file I need to move from one folder to another
First was doing the obvious:
System.IO.File.Move("Y:TempFile.txt", "Y:Temp2File.txt");
Not much to go wrong here, right? As long as I have the correct permission to write in the folders and the folders exists, this would normally go smooth. But for some reason it only copies the file. The source file still exists, but it has successfully copied the file to the destination folder. No exceptions has been thrown or anything... but the file still exists in the source directory
I then changed the code to the following:
System.IO.File.Copy("Y:TempFile.txt", "Y:Temp2File.txt");
System.IO.File.Delete("Y:TempFile.txt");
Console.WriteLine("See mommy, no Exceptions");
As expected the file copies correctly, but the delete command is completely ignored. The file is not deleted, but the Console.WriteLine command is called
I'm running the application as the logged in user. The user has permission to delete the file. If I try from Windows Explorer, the file is correctly deleted. Unfortunately my application refuses to delete the file and even worse, it will not even throw an Exception.

C++ :: SDL Deleting From Vector
Apr 13, 2013Simple rect collision detection
bool check_collision(SDL_Rect *box1, SDL_Rect *box2){
if(box1->x+box1->w<=box2->x)return false;
if(box1->x>=box2->x+box2->w)return false;
if(box1->y+box1->h<=box2->y)return false;
if(box1->y>=box2->y+box2->h)return false;
return true;
[Code] ...
The order of the game is of course standard.
1.handle input
2. handle logic
3. render
4. update
It's all pretty simple and straight forward, but oftentimes (not always) when the weapon hits the asteroid, the program crashes. If for example I turn off the delete main_weapon[i] and main_weapon.erase(main_weapon.begin()+i); the program works perfectly, but of course the bullets go right though the asteroid object, which is not what I want. It's only the weapon deletion which is causing no end of trouble.

C# :: Deleting LIST From CSV?
Mar 7, 2014Basically, I have a LIST that is saved in a CSV file, and I need to remove a particular record after using the search feature (which populates the fields from the CSV file... i.e. ID, Name, etc...).
I am able to get the details that are in the text fields by using a search feature. This is then put in:
logic.remove(tempIndividual)
In class myLogic.cs, then I have this method:
this.individual.Remove(tempIndividual)
Upon debugging, I can see that tempIndividual is populated with the correct data. However, I need to remove this data from the CSV file. Am I on the right track, or totally off? Maybe it is not complete, cause I can't get to the part where it actually removes the data from the CSV, or at least I'm not sure if .Remove is able to do it on its own.
C++ :: Adding And Deleting From List
Dec 11, 2014I am writing a program to list the 8 planets, then you select which planet you want. it gives you the mass of the planet, the radius, then you use the mass and radius of the planet to find the surface area (sphere formula) and the density of the planet. Along with those options, you have to add and delete a planet from the list and then sort them alphabetically. All i am having trouble with is the adding and deleting part. The code the adding and deleting from the list would go in cases 9 and 10.
heres my code as of this point.
