I'm getting an error message that I can't seem to fix. The error clearly states that during the link aspect of the debugging and build there is an error that says that the stdio.h file is either missing, invalid or corrupt. When I try to program using any of the other headers I'm getting the same error. The files are there I can see them in the include folder, so I'm asking what can I do to fix all these headers and beware I am a beginner at programming and using any kind of compiler.
This is the error I receive.
1>------ Build started: Project: hello, Configuration: Debug Win32 ------ 1>LINK : fatal error LNK1123: failure during conversion to COFF: file invalid or corrupt ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped =========
This is the compiler I am required to use for an online course and all instruction is given for the Microsoft visual 2010 express edition. Also the only file I think that's being referenced is the #include <stdio.h>.
I have the following code. however, when I debug it gives an error saying" vector subscript out of range"
Vector based mufti-dimensional arrays
Vectors are a STL container that allow you to store pretty much anything in them. When used correctly they can be very powerful containers.
They provide an added benefit that they will automatically remove the memory they use when they go out of scope. This means that objects stored within a vector do not need to be de-allocated (but pointers to objects do). You can also do some interesting things with dynamic multidimensional arrays with vectors.
For example, if you only allocate the first dimension, then use the .push_back() to add records to the 2nd dimension it's no longer a grid, but an array with a dynamically sized 2nd dimension (much like a street of buildings each with a different amount of floors).
This functionality can be achieved using pointers, but is much harder to do.
#include <iostream> #include <vector> #include<conio.h> using std::vector; using namespace std;
I am debugging a library. I can step into the code however the watch window doesn't show the values of any variables. It will display a message in the value field:
Code: m_pParentCXX0017: Error: symbol "m_pParent" not found
Interestingly it does show values for local variables in that function but not member functions. Most of my data members are member function though that I want to debug. I am using VS2010.

I've been using a timer to refresh the listview on my application, but after half a second, I get the error message at first try/catch method in RefreshPlot() in PlotComponent.cs:
Quote An exception of type 'MySql.Data.MySqlClient.MySqlException' occurred in Marketplace.exe but was not handled in user code
Additional information: There is already an open DataReader associated with this Connection which must be closed first.
Basically I wanna make my textbox to contain only positive numbers. I was able to do that via masking and regex. I should let you know that the column is bound to a variable which is an int. Therefore, the user always have to type an int (no letters or characters). Like I said, I have been able to prevent user from typing anything but numbers.
Now to the problem:When the user leaves the cell blank and chooses to get out of that cell, they'd get "Input string was not in correct format" next to that cell.
-My approach is: whenever there is nothing in the cell, just replace it with 0. I have code that I thought will do that, but it wont. Seems like the cell was not null, because the if clause won't execute. This is the code:
-Another approach is to change the display or the error message to like "Please enter a number." I have tried doing this but no luck. When I try this concept with the code below, it pops me a dialog box say "Do you wanna change the value?". I dont want it to pop up a dialog box. Also, i was looking for a message that I tried to give it. Looks like it doesn't even get in the if clause because I have checked. And its because its not null? I dont know. This is the code:
private void gridView1_ValidateRow(object sender, DevExpress.XtraGrid.Views.Base.ValidateRowEventArgs e) { GridView view = sender as GridView; GridColumn priority = view.Columns["Priority"]; if (view.GetRowCellValue(e.RowHandle, colPriority) == null) { e.Valid = false; //Set errors with specific descriptions for the columns view.SetColumnError(colPriority, "Incorrect Value"); } }
PS:I have checked that both of these methods get executed, so it isn't like they don't. I used some console.write stuff to check this.
Every time I try to compile this, I get the error message, "error: no matching function for call to" on lines 18, 45, and 46. Basically every time I try to call on the function sales and printStock. I don't know what the message means or why I get it.
#include <iostream> #include <fstream> #define N 10 using namespace std;
I am trying to get this simple validation loop to work so that it only displays the error message when the input is outside the range 1-3. yet it always seems to display the message.
I need to have a program display an error message if the variable entered isn't an integer but then I want it to cin again. I have this but it doesn't work:
cout << "Enter an Integer: " ; for (;;) { cin >> var; if (!cin) {
[Code] ....
I am not sure how to do what I want and this doesn't work, it just repeats That wasn't an int.. over and over again.
getting an invalid null pointer error message after a successful build. This program is supposed to ask for firstName, lastName, age and maJor and keep doing so until the age that is input is 0 and then the program closes. Here is what I have.
#include <iostream> #include <string> using namespace std;
I'm trying to print a single linked list backward with functions/classes. I have created the main file and 3 header files. But I'm getting an error on one of the header files, linkedListIterator after adding #include "linkedListType.h". It says that "linkedLlistType.h" is calling itself. And when I try to run it, I get an error of "too many header files." I have tried changing the headers many times, but nothing seems to work.
.cpp file:
/*(Printing a single linked list backward) Include the functions reversePrint and recursiveReversePrint, as discussed in this chapter, in the class linkedListType. Also, write a program function to print a (single) linked list backward. (Use either the class unorderedLinkedList or the class orderedLinkedList to test your function.)*/
Ive narrowed down my crashing problem ( using printf's ) to a malloc call I had to use printf's because when i ran the program in Codeblocks debugging mode, it did not crash and ran fine, but when i ran it normally, it would crash, giving me this error:
fatal signal segmentation fault (sdl parachute deployed)
Inside my code, I created a malloce function that checks malloc for me ( so i dont have to do it )
I have a bug and when I debugged in some point i needed to know whats inside my char **grid , when i hold mouse over this variable in debug mode i can only see hex or address.. ! i cant see my values grid is 10 * 10 table which hold a number from 1 to 3 .... is there any way for me to see whats inside ?
I want to know what was wrong with my code when I submitted. It's a Traveling Salesperson Problem, and the code is complete for the most part. I just can't seem to find what's causing the segmentation fault even after attempting to debug with gdb. Something is supposed to be wrong with line 76, but I don't see how my arrays are messing up. I've looked through this code countless times, and I know I'm just missing something small. I just don't want to end up making whatever mistake I made on this again in the future.
I checked that while identification has a value, the IDLabel.Text was run just fine, but if identification has null value, IDLabel.Text was skipped totally...
Code: #define DEBUG_NEW new(__FILE__, __LINE__) #define new DEBUG_NEW
and overloading operator new for debugging purposes. It usually works but there is a problem when use operator new syntax in code instead of directly use new. I can change my code but i can't change third party's code. Something like this:
When running my code in Visual Studio, there is a particular point in the code where my program is crashing. To debug this, I am adding a break point in Debug mode just before that point, and observing what happens as I step through the code. However, to get to this break point in the code takes about a minute of running the program. So I'm wondering if there is a tool in Visual Studio to reload the state of a program's memory from a previous run, so that I can immediately get to the break point without having to wait for a minute each time?
I am making a MFC application with VC++2012 with receiving data from Serial Port and the data is stored in a Listbox, then after processing (convert into numbers) and get these data to draw a sine wave on the chart. (I intend to make a virtual oscilloscope).
Everything works ok at the beginning, but after receiving about 300 items or above (in the Listbox) the value seem stucking (or lagging) and work very slowly.
I receive data by the SerialPort_DataReceived() method, and process of converting and drawing chart also in this method, I think this makes the system overload!!
I see there's something called a manifest file but VS C++ EXPRESS seems different than non-express. The solutions I've seen show applets/tabs that I don't have in Express.
In one of my physical DEBUG folders are some .manifest. files and some a .res and .rc file.
I know you need to edit the XML and change asInvoker to requiredAdministrator (or something like that).
The confusing part is if I go into Project Properties, MANIFEST TOOL caret/tree, under INPUT AND OUTPUT, it shows this .manifest file is OUTPUT. It's as if it rewrites it every time with some defaults? I have edited it, but I see it's back to asInvoker. There is a spot to put in a ADDITIONAL manifest file (or .res file).
Does a manifest somehow affect the physical .exe file (something is imbedded in it??)?
How do I change my project to make sure that the .exe always runs as Admin? Will doing this ALSO allow me to DEBUG it in VS C++ EXPRESS without having to do anything different (play with manifest or run VS outright with Admin level)?
