Hi,
I am new to the vc++ concepts.
How can i give the tab order for the controls in my dialog box programatically?can anybody suggest me the right approch for doing this ?????
Thanks in advance....

Tab order depends on the order of child windows. Well, you can change the child window order by calling SetWindowPos()[^].

Check this link[^]. Its exactly what you're searching for.

dynamic array

Sunday8PM24-Aug-08 23:31

24-Aug-08 23:31

Let's say I have a class called MyClass. I want to store objects of this class in a dynamic array and by dynamic I mean the ability to add any number of object one by one, not a predefined number. I have googled it and "dynamic array" appears to mean that you can assign a dynamic length when you create the array but that's not what I'm looking for. I want an array with an unspecified length that I can add any number of objects to.

Would something like this work?

MyClass *MyObjects = new MyClass[];

MyObject[0] = MyObject1
MyObject[1] = MyObject2
MyObject[2] = MyObject3

If I have understood arrays, increasing the number will make it jump to the next place in the memory (8 byte jump forward if the object takes 8 bytes). I'm worried that since I haven't specified the length of the array before, it might write over something else since it isn't expecting the array to use it.

I haven't tested the code, I just came to think of it.

Would the code work? is there another way of doing it? Is it possible at all?

Any help appreciated.

You could try the CArray class in MFC or you can use the vector class in STL.

If you are telling this because of the empty [], you are wrong. A few days back, I came to know that an empty [] will return a pointer pointing to a memory of size 1 byte. Thats why I said, it will crash.

Just try..

The code you have suggested means that the array elements can only be added in the source code - any dynamic changes in the code are not possible.

If you are wanting to dynamically add array elements at run time, this link may help you solve your problem.

Dynamic arrays means - you are free to allocate any number of members at runtime. But still you should specify the number of items in you dynamic array. The only flexibility is - you could decide the count at runtime where in static arrays, you cannot.

Sunday8PM wrote:
MyClass *MyObjects = new MyClass[];

You've to specify the array size.

int ArraySize = 10;
MyClass *MyObjects = new MyClass[ArraySize];

Sunday8PM wrote:

You cannot instantiate arrays without specifying the size.

Well, you could use stl containers such as std::vector where you'll be free from the array size headache.

Jijo.
