My Application is C# winform
I am facing below error at the time of form close and end of Dispose() method .
The instruction at "0xXXXXXXXX" referenced memory at "0xXXXXXXXX", The memory could not be "written". Click on OK to terminate that program.
how to avoid / catch this error .
I am trying to write a client/server application that takes input to an array of structures from the user,stores the data in a shared memory segment and then writes the same to a file when I close the application. How do I get started? And how do I ensure that the server stores the data correctly? Also, the server needs to be a concurrent server that accepts connections from multiple clients.

#find server*/watson*/log/ -name "watson*" -type f -newer ./tmpoldfile ! -newer ./tmpnewfile |
xargs grep "WX Edit Bug" | awk '{print $8}' | sort | uniq | wc -l

I see server memory keep on increasing whenver client disconnectes and connects.The server disconnects client if client didn;t send valid credentials.
When client is trying to connect with invalid credentials the memory is keep on increasing.
Here is the code that handles disconnection.
try {
if (state.workSocket != null) {
log.DebugFormat("ssl socket displose,{0},{1}", Doomed, IP);
state.workSocket.Shutdown(SocketShutdown.Both);

I am compiling it on a 64 BIT ubuntu machine having 64GB ram using gcc 4.6 compiler. I am getting the following output Error allocating memory. But (914*866*2724) is approximately 8 GB, Whats wrong with the code?
I am writing a very basic database in C++ and I am accessing the data from a web browser. I am using the opensource Mongoose web server code....
I have an issue...
The way the DB works is this: on starting, the DB loads a json file of all of the data into it. I have a class called DatabaseLoader that does this - it is the class that gets rewritten depending on the data structure of the json.
This is passed to vectors (vector<Node*> and vector<Edge*>) as references from Graph object.
Once the DatabaseLoader has finished it can be destroyed and any memory allocated objects it created (except the ones in those two vectors).
From then on, the Graph object is in charge of all of the elements in the database that are stored in the two vectors. When the user browses to htpp://127.0.0.1:8000 they see the json representing each object in the vectors.
All good so far....
However, when I repeatedly hit refresh in my browser (and call me insane...) at quite a fast speed I get this error:
Code:
main(29855,0x7fff76763310) malloc: *** error for object 0x7f98b2829408: incorrect checksum for freed object - object was probably modified after being freed.
*** set a breakpoint in malloc_error_break to debug
[1] 29855 abort ./main testing.json
It seems to me this would be if I tried to "delete" and object twice, or if one of my objects was overwriting memory somewhere. However I am not recreating anything, I am just looping over the vectors and printing out the content. When I refresh slowly, I dont see this happen - i did it quite a lot of times, but when I do it fast I think it is happening.
So is there any possibility of me hitting the c++ web server to quickly and it is trying to process the data twice, causing some sort of memory error - i.e do I need to implement threading or something??
I can paste code, but there is quite a lot now....
It is been several days that I am stucked with the segmentation error and I do not know anymore what to do I try to do a loop over my function but it is working only for my first iteration. Here the code:

I would like to iterate over solvep (since h is changing at each iteration..I usually add other fct but now I try to debug why the loop is not working.).The first iteration is working fine but not the other iterations.
I am getting "driver could not be loaded due to system error 8" error while connecting to SQL Server 2005 from VC++. Its also throwing out of memory error. Basically i am developing and ISAPI dll. I use the following code to connect to DB.

Save.open("SaveFile.mystery");
if (!Save.is_open()) {

I have the following code in the cellmouse event to get information from a selected row.

but when i select a collumn, i recive an error because i'm selecting a cell with the mouse and i dont have code for that selection. My question is how can i put an "if" on the beguining of the event so that he can determine if it's a header or not.

I'm taking an operating systems class and I'm trying to write a script that would execute a program in Simple OS.I"m not sure if this is the right place for this because although the entire OS is written in C, "asm" are assembly language code. Anyway when I run the OS in virutal box and try to run a program, I get a "Fatal Execption" in a loop until the entire OS crashes. So then I try to debug my code BUT when I add printf statements and try to run the code again I don't get to the "fatal execption" and the entire OS just crashes. 1) why can't I add print lines? 2) what's going on with the fatal execption?

I was created winform application with sql data base, after i created it i was converted to the installer file,for the other users but when they run the application did not connect to the database, how i fix this stuff...?
View 1 Replies View RelatedHere is a working C++ program and its output that reads the names of a certain number of functions whose names are written in a disk file that provides the control parameters in a near-real time fashion. Based on this information, the program calls those functions whose names were given in this text file as parameters. The method I have used is to build a map of functions that connects the names of the functions to the actual functions. Once this map is created, then it is very easy to iterate in such a way that only those selected functions are called.
So far this is working well, and it makes the logic of the code easier because ultimately there will be a large inventory of functions (probably hundreds of functions), and this way of pre-building a map of functions avoids writing hundreds of if statements in the code. Of course, pre-building this reusable map in the background is still equivalent to writing that many if statements, but at least it makes the code very compact and much more automatic, since it is done only once.
But I now have a related question: In this case (when the selected subset of functions to call is given as incoming data as in this example), does C++ make it possible to avoid using maps of functions, by directly applying the string variable that holds the name of the function in order to call the original function immediately For instance, if a string variable s = "MyFunction", then is there a more direct way of using this string as if it were the actual function whose name is spelled exactly in that way? This would make the code even more compact.
Here is the sample test code for the map of functions, and its output:
First of all here is the text file "FileForNamesOfFunctions.TXT" that contains the part of the "data", which is the set of functions select from from the inventory and only call these:
Code:
function2
function3
function5 And here is the C++ code that uses this "data":
Code:
#include <fstream>
#include <iostream>
#include <sstream>
#include <string>
#include <vector>

i cant display the data written to this file in a switch statement (case 2) what am i doing wrong..the file data is being written into the text file but i cant display it
insert
Code:

#include <stdlib.h>
FILE *fp; //creates a file pointer
typedef struct date_info

I've found that with streamwriter(sw) the data isn't displayed with the written to document until you either leave scope or use sw.close I'd prefer to keep sw open as I will be writing to the file in and out, sometimes very frequently, but would also prefer the data to be viewed in real time. Is there an efficient way of going about this?

For school we have to create a blackjack game using windows form. I had to store the images of each card into a sorted list so i created a class called cardList and created a constructor which contained the the sorted list called cards. So it looks kinda like this:
public class cardList : Form1
{
SortedList cards = new SortedList();
public cardList()
[Code]....
There's probably a few other errors, I'm still trying to figure this whole c# thing out. why the error tells me (on the line that contains c.cards.GetByIndex(cardNumber);) that cards is inaccessible due the its protection level.
