I have client-server program that written with c++. Both client and server program are working on my computer.Also, I test it on many computer.There is no problem with it.But, When I try to run that program on the my windows server 2003. I get error which on the below.
[URL] ....
I researched it and someone said that it is related 32-64 bit system . My windows server is 32 bit. And I am compiling as 32 bit. But I still get error , can not get any answer with it.
I made client server program with fork ,without using signal handler because I want to see the status zombie for parent server, but when i execute "ps" command i didn't see anything for server or client pid or ppid ,i wonder about how to show the server and client process coz when i execute commad "ps" i saw only ps and bash processes???
I Was Try To Change PictureBox To The Memory Stream And Then I Read Memory Stream Bytes And I Send Over The Netwrok Here Is Code
MemoryStream ms = new MemoryStream(); pictureBox1.Image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg); // we save the image in side the Memory strem byte[] pic_array = new byte[ms.Length]; ms.Position = 0; ms.Read(pic_array, 0, pic_array.Length); //
[Code]...
but when i want get the Data o mean Bytes from Network tream How can i save in memory stream then dispaly in the picture box ? i try some thing but it is gave me error !

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....
I have added sql browser & sql server in fire wall, and also enabled tcp port 1433 and udp port 1434. the above connection string works perfect when i run it in the server machine, but whenIi try to run it on other machines I am getting an error that server is not available or cannot find the specified server.. I desperately need to access my database through an url. ie., through internet..
I stored multiple images in MySQL SERVER 2005. Now I want to retrieve particular category of images into multiple picturebox at runtime in C# Windows application. i used the following code in my final result form at form_Load using c# windows apps.. But it displays only one picture at run time.
SqlConnection con = new SqlConnection(@"Data Source=ttt-PC;Initial Catalog=Query_Image;Integrated Security=True"); SqlCommand cmdnew = new SqlCommand("select pic from Image_Category where IMG_Cat='" + searchvalue.ToString() + "'", con); con.Open();
I have a desktop application in which i want to copy files from my local computer to an online server. I have the user name and the password of the server. is there any way like

Above code write in console application, same logic implementing in windows service, but i want data receiving continuously
I m making calendar in server control page by taking composite control.I am also adding textbox in each cell of calendar.

Can't access textbox text and date or controls of server page in website(default.aspx) page.
Im having trouble on getting the quantity up of the variable "item.iqty". For example the current quantity is 5 and in this function, the user inputs a number and it should add to the variable "item.iqty". So if if the user inputs 2 then the current quantity should be 7 now but in my program it hasnt changed. its still 5
I'm trying to implement a linked list using my own node class. I've created functions to add to the head and tail, return the size of the linked list as well as the value stored within the current pointer.
However, my problem is that when I wrote a test program to see whether my list worked, my list did not appear to increase in size past 1 item in the list.
this is the test program I wrote:
int main() { int counter, data; linkedlist *my_list = new linkedlist(); cout << my_list->size() << endl; for (counter = 0; counter < 5; counter++) {

I'm sure it's probably something simple that I've overlooked . But I'm still relatively new to the concept of dynamic memory allocation.
I am trying to make a double array, but I keep getting an error Segmentation fault (core dumped) when I make more than 105 elements in the array. I need to make 114 elements.
I am building my array with myarray[999] and increasing the number doesn't seem to do anything.
I am new to programming all together but i have been writing a program in c++ and im coming up against an issue with my array.
#include<iostream> #include<iomanip> #include<string> using namespace int main () { int a ; int b ; char answer ('Y') ;
[Code] ....
I am trying to get the program to increase say year one by 1 when the condition is met i have tried
if ( a >= 70 && a <= 100 && b == 1) {grade [0][0] = 0 + 1;}
and
for (grade[0][0] = 0 ; a >= 70 && a <= 100 && b == 1 ; grade [0][0]++) {grade [0][0]= 0 + 1 ;}
Now all that i want is that the array will take the information from int a and int b and then add 1 to the appropriate part of the array . I have tried putting it in deferent places but its not working for ether. the program will run but it will not add to the array.
All I have so far is a rectangle that prints 5 stars in length and 20 lines in length. What I want to do now is have each new line print an extra space more than the line before it and then print 5 stars.. This is what I have so far:
Code:
#include <stdio.h> int main (void){ int i; for(i=1; i<=20; i++){ printf("***** ");
