EIther you need to think about how you word your questions, or you're typing your homework direct into the site without any thought. My money is on the latter.

Did you overlook CStdioFile::ReadString()?

Hi guys
I have been trying to copy a process's module(my own proggy). This is the scenario:
There is a process lets call it "Main.exe" which loads plenty of modules and among those modules there are 2 modules called:
1. "Checker"
2. "Copyer"
Now this Checker module checks the Copyer module once in a while but i want to somehow change some stuff in Copyer using Read/WriteProcessMemory but if i do this then Checker will detect that i have changed something and exit the process.
What i want to do now is somehow copy the "Copyer" module and then reinject it in the process so that there are 2 "Copyer" modules. Then i want to fool "Checker" into scanning the fake module that i copyed/injected in the process.
I know that this is possible but i dont know how to do this. Could someone please help me?
Thanks in advance

Here is a program, in the release version, there is a "Run time Error" appreared some times, I can get the module name and the address of the function, but the address is an Invalid value.
It is not occured either in the debug version or release version with debug information, and it is not occured anytime.
when I press the debug button, it will not show the debug enviorment but just shut down the program.
It is an ActiveX program I wrote and the error occured when it is being created.
How can I find out the reason of this bug and how to debug in this situation?
Thank u!

Hello Everyone,
I'm a newbie, Please help me!
I'm adopting the code that could redirect a console output into the MFC Edit box.
My problem is, i want to have a live redirection from the console output to the edit box because i have a console application that will run about 5-10 mins and produces lots of information (output) in between those time in the command line.
My recent code will just wait the application to finish up before it could redirect the output from the command line to the Edit box.
Please help!.... thank you very much..

Dear all,
i need to apply a set of changes to the project settings such as compiler options, linker options etc programatically. I found an MSDN article about automating MSDEV.
http://support.microsoft.com/kb/q247035/[^]
In the msdev automation interface there is a COM interface IConfiguration for each build configuration. I think by using that, we can update the project settings. But didn't find any useful information. Please help.
Regards,
Jijo.

This is rather general question wich entered my mind when i read an answer written by Christian Grauss to a question a little further down. He said that in C++ variables should not be declared until they are used. Why is that ? And why is that different in C ?

In C, you need to declare your variables at the top of your function (otherwise, you'll get a compilation error), which is quite messy (you have a bunch of declared variables that you don't know their purposes). In C++, you can declare your variables when you want in the function, so, it is better (IMO) to declare them only when you need them.
|
|
|
|

To add Cedric;
By declaring it at start, it will be in memory unnecessarily for longer time, when its required somewhere down in the code. So declare it when its necessary. And its always easy to track it in this case.

Its by standard in C.

If you create them at the top of a method and then at some point during the method you return without using the variable, then you have created it for no reason. This could be expensive if the creation takes a long time, or uses a lot of memory, or if the object has several base classes for example.
Typically you should only create a variable at the point you are going to use it, this an help the compiler perform its optimisations too.
It also makes the code easier to use and less prone to bugs as you cannot accidentally change the variable before first use if you create it only where you need it.
You can also control the scope of the variable so it only exists for as long as it needs to.

I guess I need to answer.
As has been said, in C, you have to do it at the top.
In C++, you don't, but some do, just because they learned from someone who does it that way, because they are used to it from C. Declaring the variable close to where you use it makes code more readable and less prone to bugs.

I learnt C++ first, then had to "backport" myself down to C when I got a job where the lead programmer was afraid of this new fangled OOP stuff.
You wouldn't believe how long it took me to realise that you had to pre-declare all your variables - there was much confusion before that!

In C, you had to declare variables before any staments. In C++, you can declare variables at the point in which they are needed.

Hello,
I am trying to examine MathType (Equations) OLE data.
My daughter Stav is totally blind. She is learning in the 10th grade and she needs books in Braille. I contacted the publisher of the Mathematics book she needs to learn from in order to produce it in Braille. I received a Word document containing embedded MathType equations.
This is a one time job, so if some of the steps should be done manually I do not care.
I finaly reached the conclusion that each equation data is kept in OLEDATA.MSO, MathType documents the binary data but I can not find it inside the file. Can someone help with the format of the file?
I saved the Word document as XML (Office 2003) and found all
//o:OLEObject[starts-with(@ProgID, 'Equation')]
But I do not know how to go from here
Thanks, Reuven

Hello!
I have a problem with push-like checkboxes in my app under WinXP. When I embed manifest my push-like checkboxes look cute (round corners etc). But when mouse moves over that button it is hilighted. When mouse clicks it is still hilighted so the user cannot see check state (is button pushed or not). User is able to see the actual check state only when mouse is moved off the button. So in the case of push-like checkboxes this fancy hilighting is bad.
I want to turn off hilighting when button is in checked state.
The only way to do it (as I can see at the moment) is to subclass button window class. But the problem is I don't know to which messages to pay attention and what to do to stop hilghting.
What can you suggest?
------------
I love you
