I got this message after i delete allocated class object, should i check the deleting? if it's object what is the correct way to delete/delete[]?
theCars[nToDel] is a static array of pointers
bool Cars::deleteElement(int nToDel) {
if (theCars[nToDel] != NULL) {
delete[] theCars[nToDel];
theCars[nToDel]=NULL;
inUse--;
return true;
} else
return false;

In my program I open two files and write data into each, and close them. this is done in a while loop.
int main() {
while() {
myFile = fopen("file1.txt","w");
myFile2 = fopen("file2.txt","w");
// write data into files using fprintf() in a for loop
fclose(myFile);
fclose(myFile2);
}
}
However, after some iterations the fopen() for myFile2 fails.

I've created a new dialog in my MFC dialog based application. the new dialog contains 5 control buttons. The following happens and I don't understand why?
1. click on buttonX. (result ok, OnBnClicked message is sent)
2. click on on any place of the application, but not on the dialog.(removing focus from dialog)
3. click again on buttonX (FAILED, OnBnClicked message is NOT sent). but if instead I click on any other button in the dialog (result ok, OnBnClicked message is sent).
And when I do:
1. ...
2. ...
3. click on the dialog area just to set focus on the dialog again
4. click again on buttonX. (result ok, OnBnClicked message is sent)
**I need to do step 3 only if I want to click again on the buttonX! why?? I think it related to SetFocus() but I m not sure how.
I've tried different style like, tool windows, overlapped, popup. it happens in all the cases.
Code:

I am trying to build a program that takes a user password (6+ characters, One uppercase, one lower case, and one number), and checks for errors. The idea is that if the user is doing something wrong (say, forgetting to use an uppercase letter), the program will tell them what the error is, and prompt them to enter the program again.
I get through the building process without errors, but whenever I run the program, I get this error: [URL] ....
Here is my code:
#include <iostream>
#include <cctype>
using namespace std;
bool checkPass(char [], int); //Password Checking Function

Basically, I'm moving a VC project from my Windows 7 build machine to a new build machine that's running Windows 8.1. One of the pre-build steps (for a particular project) runs a script which needs to call the M4 macro processor (which is installed on my C: drive). I've been pretty careful to set everything up the same on both machines (including my PATH) but when I try to build the project on my Windows 8 box, MSVC's IDE shows me this error output when running the script:-
m4 failed with exit code 255
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'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:
private void gridView1_CellValueChanged(object sender, DevExpress.XtraGrid.Views.Base.CellValueChangedEventArgs e) {
GridView view = sender as GridView;
if ((view.GetRowCellValue(e.RowHandle, colPriority).ToString() == "") ) {
list.ElementAt(this.gridView1.FocusedRowHandle).priority = 0;
}
}
-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.
Code:
#include<stdio.h>
void main
{
int i;
int marks[10];

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.)*/

I have a MFC Com Dll that has a CDialog. In the OnCreate event I create an ActiveX control. The dll is hosted inside an executable of mine. In this scenario everything works fine!
The dll is also called from an external executable and then a Debug Assertion in OCCSITE.cpp occurs when I create the ActiveX control. I suspect that in the executable there is no AfxOleInit. I spend some time with this problem and tried to CoInitialize, OleInitialize, AfxOleInitModule and even AfxOleInit in the dll. But all that does not change a thing. If I understand the mechanics then this is an intended behaviour and should be done in the host exe.
What I observed in the OCCSITE.cpp:
Code:
_AFX_THREAD_STATE* pState = AfxGetThreadState();
if (!pState->m_bNeedTerm && !AfxOleInit())
return hr;
In my executable m_bNeedTerm is 0 and in the external one (where the ActiveX does not work) it is -1. In AfxOleInit this is explained as a special flag to prevent the dll from doing an unnecessary OleInitialize. But as I said even if I call OleInitialize myself I get the Debug Assertion and the ActiveX is not visible.
Is there anything I can do to make the ActiveX control work in the external application? Obviously I cannot Change anything in the application...
Following function is causing run-time assertion. I am using VC6.0 professional version. My OS is Win7.0. I am calling the function from OnDraw. OnDraw does not contain any other code other than the function call code:

x1=20;
y1=100;
x2=200;

int color1=0;
int color2=0;
