hey
I am new to c++. I am trying to create a editor program.I am stuck at how to open a dialog box where it asks to open a file from any directory (my pictures etc ) and then save that file.i tried using the form to create a open/save dialog box- in design mode - but when i compile it,its giving me errors like

button1_click has no member...if anyone who can guide me through this that would be amazing thankyou.

i am using visual studio 2013

here's that part of code

				System::EventHandler(this, &Form::button1_Click);
		}

On line 3 I'd say that is the constructor of MainWindow. On line 7 there is Form. If the encompassing class is MainWindow then you cannot use Form with this.

I am new to c++.

Just to make you aware (just in case you are not already). Strictly speaking you aren't writing C++.

From:
https://en.wikipedia.org/wiki/C%2B%2B/CLI
C++/CLI should be thought of as a language of its own (with a new set of keywords, for example)

Remove line 22/23.

The function button1_Click(...) is missing. This should have been created by the designer. Did you delete it accidentally?
So let the designer create it again for you. Or (if you now the signature) write it yourself

thnx mutexe for pointing it out but i already knew that =)

@ coder777

do you mean void button1_Click(System::Object ^ sender,System::EventArgs ^ e)
its there in the code line number 114-115... =/

In that case I apologise mate :)

Ok, I see.

No, this is a local function inside openFileDialog1_FileOk(...) (which is not allowed in C++). Move button1_Click(...) outside of the function/inside the class.

nop i am sorry it was my mistake i should have mentioned that i am working in managed c++ which is a new territory for me =)
