I want to define a vector of TextBox (or any compnents) in VC++ project (windows form).
I wrote :

std:vector <TextBox^> txt_box;
//then I push the elements back in the vector using

txt_box.push_back (textbox1)
// for all the text_boxs in my form

but this code does not work.
if you have any idea plz help and thanks.

What do you mean "it does not work"? Would you take your car to a repair shop and tell the mechanic the same thing? I hope not.

Is that CLR/C++ code (e.g. Windows Forms) you posted? If so, you can not use the standard templates like you would in c++. Instead, use the files in include\clrext folder.

I put the code above in the namespace out side the class .And I put the push_back statement in a method in my class .and all of them are in form.h file.
what happened is the compiler displays an error message and it says that :

can't convert from 'TextBox^' to 'TextBox^ const&'

are there any way to solve this problem?

How is the TextBox object declared? Are you trying to use the same instance over and over because that won't work even if the compiler didn't complain.

I got this to work ok. The code I added is marked in Red

            // textBox1
            this->textBox1->Location = System::Drawing::Point(91, 50);
            this->textBox1->Name = L"textBox1";
            this->textBox1->Size = System::Drawing::Size(100, 22);

            this->textBox2->Name = L"textBox2";
            this->textBox2->Size = System::Drawing::Size(100, 22);
