Hello Coders,
I am writing a program in c++ in code blocks on "Win32 API". I have created a window with menu named "New" and there is a option in it "Display"(i.e. New->Display).

I want that on clicking the "Display" some data should be displayed( & not paint) on the same window(not in another window like messagbox).

Please Can u tell me how can I do this and if u have any link to video on you tube helpful for me.

Thank you Anticipation

What I have tried:

I have tried IDM but it was not supported in code blocks.

Solution 1

The only way to display things on that window is by using the WM_PAINT event. This is explained in detail in lots of tutorials, such as EFNet #Winprog[^], Win32 Programming - FunctionX[^] etc.

Richard they all use IDM and it want solution without IDM. At least how to respond to the menu items.

Suryakant Turing 25-Feb-16 2:47am

Richard that was my mistake. I was taking IDM term as predefined.

But I still have a problem, I want my data in detail form and not printed when I click a particular menu item.

Sorry, but what does that mean?

Suryakant Turing 25-Feb-16 11:41am

I mean that when I print "Hello Window" on the windows then it can be - selected, copied by the mouse.

And this does not happen when I use WM_PAINT to print the text.

Use an Edit control in the client portion of the Window. It does all the painting and text control for you.

Suryakant Turing 26-Feb-16 9:05am

Thanks Richard. Now I got it.
But I have a function that prints the text using "_tprintf", and it doesn't print the text on the window when I call it. I implemented the Edit control on the client window.

_tprintf (or any other printf derived function) prints to stdout (the console) so is not relevant in a Windows application. I strongly suggest you go and work through some of those tutorials that I gave you the links for, as they explain in detail many of the issues that you need to understand for Windows programming.

I followed your link, found some important issues also but still I doesn't overcome my problem to display(not print) my text(from a variable TCHAR type) on the window I created, whenever a click on a specific menu item.
Give me some idea or content related to this only.

Without seeing your code, and understanding what you are trying to do it is difficult to suggest anything. If you do not understand the issues involved in programming Windows applications then you are not going to learn it in a Quick Answers forum. I strongly urge you to work through the tutorials I gave you the links for, as it will show you how to deal with all issues, from handling menu selectors, to displaying text and graphics on your Window.

You also need to understand that TCHAR is not a type in itself. It is merely an alias for char or wchar_t, depending on whether your application is being built for ASCII or Unicode.
