I'm confused:
1. TCP/IP already takes care of packet delivery; it makes sure it arrives, and if it doesn't, it gets resent. Why implement another queue on top of that? That just creates more traffic, and you made a point you want to avoid that.
2. You said something about asynchronous processing, but if you implement a queue as you said, it enforces synchronization! So what do you want? Synchronized or not?
That said, I have no experience in programming this kind of stuff, I only know the theory. But maybe there's something to the many things people say about theory and practice http://wiki.c2.com/?QuotesOnTheoryVsPractice[^]

I implemented a small C++ app that reads the memory of a video game. My aim is to create a small cheat for the single-player game. I am reading the memory of a video game from another process. There is a linked list that I am trying to read in the game's memory. I am following a pointer chain to follow the linked list. These pointers point to next element in the linked list. Each time I read the pointer's address, it is something different.
Why are the virtual addresses of the pointers always different when I read them?

To stop you hacking their game.

Why? I am not cheating in online games.

I was expecting a technical explanation. Would you please give me some technical explanation about how it changes?

Why would you expect them to remain the same in a game that is running?
I have no idea what game you are trying to cheat, but you are reading the memory of a different process, so it will get run, stopped, loaded, unloaded, cached, paged to disk, and generally have a hard life - all at the whim of the operating system. Add in that the game itself will probably be moving stuff around as it runs to suit itself, and the chances of you finding exactly what you want without the source code to work form is very unlikely. And that is assuming that you have identified the actual linked list, rather than some stack based object that temporarily looked like an element that might be on a linked list, if the code actually used one.
So why would you expect everything to stay in the same place for your convenience?

If you have to ask this, then I doubt that the address you're reading is what you think it is. Not to mention what it points to. Every process uses it's own mapping from it's address space to the underlying physical addresses, and the system functions take care that each address used within a process is mapped accordingly: to some location within the momry space that is associated to this, and only this, process!
Consequently, a process can never access memory from another process, unless the two processes are set up specifically for that purpose: the only way I know to read memory from another process is setting up shared memory. And I doubt that your game allows this.
Take this with a grain of salt and a big AFAIK - I'm anything but a specialist on this topic

I'm new to MFC VC++ and trying to create a dialog base simple MFC application that display the data contains in MySQL database. Please guide me through this.
Thank you.
|
|

|

You can find here[^] a project sample of how to connect to MySQL database through ODBC ... in fact, to any kind of dababase through ODBC.

Thank you.
Could you please suggest me a good book for MFC vc++.
|

Thanks for the help!
I'am having trouble understanding why it does this
BOOL CMyApp::InitInstance(){
..........
..........
CWinApp::InitInsatnce();
..........
..........
}
Could you please explain why do we need to call two InitInstance() and what is the main reason?

When you derive from a class and override one of its methods, it's common, and sometimes required, to call the base class implementation.
"One man's wage rise is another man's price increase." - Harold Wilson
"Fireproof doesn't mean the fire will never come. It means when the fire comes that you will be able to withstand it." - Michael Simmons
"You can easily judge the character of a man by how he treats those who can do nothing for him." - James D. Miles

Thanks for the reply. 
If you don't mind, could you please elaborate the "sometime required, to call the base class implementation" part with some example.
|
|
|
|

CMyApp is derived from CWinApp, so the line
CWinApp::InitInsatnce();
simply call the InitInstance method from parent CWinApp, which is the base implementation of CMyApp::InitInstance().
"sometime required" sometime is necesarry to call this base implementation, sometime not

I am creating a simple MFC application. That has a search box which accept both string and integers to retrieve data from the Mysql database and display in the list box.
Please guide me how to create a search box that accepts when entered string and when entered integers.
|
|
|
|
|
Anything you type into a text box is a string, whether letters, numbers or special characters. If you want to use numeric text as integer values then you need to convert them with one of the conversion methods. See Data Conversion | Microsoft Docs[^].

Hello,
I created an MFC dialog application which is connected to MySql database. I wanted to create a search button/Search query for database.
Could you give me some pointers for creating functions for the same which accept string as well as Integers. Thanks.
I've read about atoi(), but still having problem.
And for displaying the search result, which one is better to use listbox or listcontrol.
|
|
|
|
|
If you have more than one column data to display, I would use CListCtrl[^] or CMFCListCtrl[^]
If you want to use an edit to use it for SQL statement, then give more details about what you intend to do there (e.g. sold > 1000 ?)
|
|
|
|
|
SQl is not greater than 1000. I wanted to create a simple application first. Like for example.. I have a table with ID(primary Key), Name, DOB...etc columns.
What I wanted to create is a search box in the dialog application. when I type the Name in the search box it will display the result in the listbox/list control box. Similarly when I enter the ID in the search box it will return the same.
|
|
|
|
|
You can use CListCtrl or derivated to display db data.
In search box you can test the user input with is_digit[^] and act accordingly (if is number then use ID to get data, or if is not number, use string to get the name and so on.
|
|

|
|
Thank you for always helping. I really appreciate the help
I have created a search function and now it's displaying in the CListCtrl and working the way I wanted.
I'll try to extend the functionality like if I select the result in the CListCtrl it will take me to another dialog that contains the details of the selected. If I have any doubt i'll post it here.
Thanks again
