The key might be secure, but if the code that validate the key looks like this :
if ( checkKey(key) == false )
{
exit(0);
}
whatever the strength of the key it will be useless.
Watched code never compiles.

Exactly. A few NOP instuctions placed in the proper location using the binary editor in Visual Studio will allow anyone to skip right over that if statement. I had realized this a while back after spending a few months obfuscating and encrypting license keys in my programs executable to only find that single critical if/else could be easily bypassed with NOP instructions. No need to backward engineer the tons of code I had worked on. 
Why people continue to pursue this is beyond me. I guess we all need to learn our lesson the hard way.

I'm looking for suggestions for a Source Code Editor control, for quick & easy reuse.
I am not looking for an editor, I am looking for a control to embed in my application.
My environment is C++ - Win32/ATL/WTL; MFC might be OK.
The typical use case is small scripts (3rd party scripting language) to quickly try out something. I'm looking for basic features such as syntax coloring, Search&Replace, optional line numbers and whatever makes life handy. It does not need to be a fully fledged editor (we support external editors well enough already.)
Any suggestions?

I'm looking for an embeddable control, not a standalone editor. I couldn't find anything on their site indicating that it's a reusable control.

What progress bar? What thread owns it? If the primary thread owns the progress bar and the saving is being done in a secondary thread, then you simply need to post a message from the secondary thread to primary thread telling it to update the progress bar.

The problem occurs while setting visible of Button6 I guess it says I try to use Button6 before it's created. While compiling the application there is no problem.This is a runtime error. Here is the surprise, if I change the header C++ Builder recogizes that the header is changed and if compile again after changing the headers the error goes away. There are a few VCL forms in my application which have changed recently. Every time I started the IDE I need to make a fake editing on their header files to get a problemless exe file. I guess there is bug but how do I get saved from this.

hello Friends
What is Best way to store Array of Dynamic Objects
I am creating a pointer for class A and Initializing 100 objects
And then again I am Initializing 200 objects.
What is Best way to store these arrays.
i used map like map<int,a*> But problem is coming that deleting array pointer is deleting from map also.
My Design Structure is like this
int size =2;
for(int i=0; i<size;i++)
{
A* objA = new A[100]
for(int j = 0 ; j<100;j++)
{
objA[j].var = TempVar;
}
mapA.insert(make_pair(i,objA));
}
But,i am not happy with this way to store array of objects in map .As I am using map as a storage that I can use anywhere in application,and bcoz of not deleting pointer it crashes sometimes.
Suggest me some better way.
Thanks & Regards
Yogesh

The first thing you need to do is find out why your program crashes and fix that problem. I have explained why you cannot delete the objects in your map and the same will hold true if you put them in a fixed array.

Can you use a vector object?
vector class reference[^]
Vector is sequence container.i need some key,data Container.
Linked list is also another option but i dont want to involve in that.
Any Other Ideas?

Yogesh

I think what AnsHUMAN was implying is that the class std::vector would take care of the allocation and deallocation - it encapsulates the array object and thereby takes away the responsibility from you. You can achieve the same however by defining your own encapsulation: see my response for details.

yogeshs wrote: bcoz of not deleting pointer it crashes sometimes
Can you clarify that statement, please? Normally, the only abnormal behaviour you can get from not deleting stuff is memory leaks, and, as a result exceptions of the type std::bad_alloc, once you run out of memory. The former will not crash your program though, so may I assume it is the latter? if so, the first thing to do would be to catch that exception.
Apart from that, there's a couple of things you could improve:
1. Storing a map that uses an consecutive integer value as a key indicates that a simple array would do the job just as well, and probably better. The only exception would be if you need to be able to insert values at the start or in the midst of your set later, and you stored key values to specific objects that you want to be able to retrieve later. You haven't mentioned such a requirement, so my advice is to use a C-style array instead. Or, if you need to be able to later add or remove entries, use a std::vector.
2. The objA variable you use to create each entry does contain only one thing, but that thing is being allocated dynamically, on the heap. As you need to make sure this memory gets properly freed again when you no longer need this object, the best way is to make a simple class to hold that variable, and define it's constructor and destructor to automatically allocate and deallocate the memory, as appropriate. That way you no longer need to take care of that anywhere else in your code. See below for an example.
#include <iostream> // for std::cerr
#include <new> // for the definition of std::bad_alloc
class MyData {
private:
A* myobj;
public:
MyData(int size = 100) {
try { myobj = new A[size];
}
catch (std::bad__alloc& ba) {
myobj = 0; throw ba; }
}
~MyData() { if (myobj != 0) { delete [] myobj; }
}
};
int main() {
int error = 0;
MyData *arrayData = 0;
try { arrayData = new MyData[200]; }
catch (std::bad_alloc& ba) {
std::cerr << "Error - bad alloc: " << ba.what() << std::endl;
error = 1;
}
if (arrayData != 0) {
delete [] arrayData; arrayData = 0;
}
return error;
}
P.S.: As I've seen from a more recent response the first point I've raised may not apply to your problem, i. e. you may need a map after all. My point about creating a class to wrap that 100-A array still holds though.
Moreover, you've used a loop to initialize all your A objects. This is another thing you could improve: use your constructor A::A() to do that! If you didn't define one already, do so now:
class A {
A() {
var = TempVar; }
};

Hello
I want to ask one more Question regarding "Moreover, you've used a loop to initialize all your A objects. This is another thing you could improve: use your constructor A::A() to do that!"
I did this in the loop bcoz I am retreiving the size only in that loop.That object array size is not constant. that can also change for each loop.So,thats why i Initialized in the loop inspite of doing in constructor.
Is there any other idea to do this?
Regards
Yogesh

You could still avoid the loop and do the allocation in your constructor, but that will take a bit more effort:
#include <iostream> // for std::cerr
#include <new> // for the definition of std::bad_alloc
class MyAllocatorHelper {
public:
virtual void* allocate() const = 0;
}
class MyArrayAllocator {
public:
static MyAllocatorHelper const* p;
static void* makeArray() {
return p ? p->allocate() : 0;
}
}
class MyData {
private:
A* myobj;
public:
MyData();
~MyData() { if (myobj != 0) { delete [] myobj; }
}
};
MyData::MyData() {
try { myobj = MyArrayAllocator::makeArray();
}
catch (std::bad__alloc& ba) {
myobj = 0; throw ba; }
}
class MyDataArray : public MyAllocatorHelper {
private:
MyData* the_array;
std::size_t current_index;
void* allocate() const; public:
MyDataArray(std::size_t size);
MyData* get(std::size_t index);
};
MyDataArray::MyDataArray(std::size_t size) : the_array(0), current_index(0) {
try { the_array = new MyData[size];
}
catch (std::bad_alloc& ba) {
if (the_array != 0) {
delete[] the_array;
the_array = 0;
}
throw(ba); }
}
void* MyDataArray::allocate() const {
A* result = 0;
std::size_t alloc_size = 0;
++current_index;
try {
result = new A[alloc_size];
}
catch (std::bad_alloc& ba) {
throw(ba);
}
return result;
}
int main() {
int error = 0;
MyDataArray* arrayData = 0;
try { arrayData = new MyDataArray(200);
}
catch (std::bad_alloc& ba) {
std::cerr << "Error - bad alloc: " << ba.what() << std::endl;
error = 1;
}
if (arrayData != 0) {
delete arrayData;
arrayData = 0;
}
return error;
}
I wrote this a bit in a hurry and didn't take the time to test it, there may even be typos. However, I hope even if this doesn't compile it might give you an idea of what I did here:
1. An abstract interface for allocating some unspecified data, which later gets implemented by the wrapper to your data array.
2. A 'static class' that your constructors can access without having to rely on parameters.
3. A local counter variable 'current_index' that keeps track of the number of allocations that have already taken place, implying the index of the data object within your array. You can use this counter to determine the correct size for that particular object in your array.
