theForger’s Win32 API Programming Tutorial
Applying Resources to a Window. Eventually you will come to know the parameters to the functions you use most. However, less code does not mean “easier” when you don’t understand the code you DO need to write, or how all of the code that is there to support you actually forgefs.
MFC Resource file notes. Assuming that there wkn32 something there to work with, we call GlobalAlloc to allocate some memory. We then call RegisterClassEx and check for failure, if it fails we pop up a message which says so and abort the program by returning from the WinMain function. This is where your program starts execution. This isn’t something you need to worry about because all we are concerned with is that we get the message and send it out, the system takes care of the rest making sure it gets to the proper window.
You should see the start page empty, as no projects have been created. Since this is the only window in our program, we are all done and we want the program to exit, so we call PostQuitMessage. For starters, for people that are just learning to program, I strongly believe that you should work with the API untill you are comfortable with the way windows applications work and wih32 understand all of forgegs basic mechanics behind things win322 the message loop, GDI, controls, and maybe even multithreading and sockets.
Here is the tutorual of WinMain. Every program, whether it is written with MFC, Delphi, Visual Basic, perl, or any other wacked out language or framework you can think of, is eventually built upon the API.
Drivers of course have even lower levels, and different sets of function calls to work with, but for the vast majority forhers windows development this is not an issue. Registering the Window Class A Window Class stores information about a type of window, including it’s Window Procedure which controls the window, the small and large icons for the window, and the background color.
When you ttuorial a button on a window, the button is the Child won32 it is contained within the window that is it’s Parent. This is just a small section to show how to add basic menus to your window.
If you are viewing this locally or on another website, visit the winprog website for the current official copy. You don’t even need to refer to the file in your program, and you can load completely different icons for your windows forgets you choose. Not for newbies, if you want to be up on managing processes and threads, dlls, windows memory management, exception handling, and hooking into the system, then this is the book for you.
Here is the code used to interface with the edit control in this example: Also contains specific information on the various windows platforms including and CE.
Tutorial: Getting Started
This is rather compiler specific, commercial compilers will have a resource editor that you can use to create your menus, but for this example I will show the text of the.
This is the last standard control that I’m going to cover for now, cause frankly they aren’t that interesting, and if you aren’t bored yet well, I am: Most of the pointer-type names begin with a prefix of P or LP.
By default, Debug Mode is always selected. While there have been numerous successful applications using the raw API has been really painful.
Number one cause of people not knowing what the heck is wrong with their programs is probably that they didn’t tutotial the return values of their calls to see if they failed or not. We’ll get to this later. List Boxes Another handy control is the list box.
The Message Loop This is the heart of the whole program, pretty much everything that your program does passes through this point of control. In the Solution name field, rename Win32Project1 to wintutorials. I’ve used LoadIcon to load the large icon because it’s simpler, however it will only load icons at the default resolution of 32×32, so in order to load the smaller image, we need to use LoadImage. This will cause the window to be destroyed by default, but I like to handle it explicitly, since this is the perfect spot to do cleanup checks, or ask the user to save files etc.
Assuming that no code modification was made, the build should be successful. Messages As you may remember from our earlier discussion of the message loop, windows communicate using messages, you send them to get a control to do something, and when an event occurs on the control it will send you a notification message back. Network Programming for Microsoft Windows Up to date information on network programming, including NetBIOS, mailslots and pipes, and of course the ever important windows sockets, complete with winsock2 and raw sockets.
Thanks for the props guys! Now sometimes we don’t care when exactly they do this, for example with our Remove button, we don’t need to know when the selection changes right away, we just check when the user activates the button. By default, when you choose to create a Win32 projectthe selected option will be Win32 Application.
And here’s the second one: Adding Items The first thing you’ll want to do with a listbox is add items to it. One of the things you would likely want to do with this list of indexes, is retreive the data associated with each item, and do some processing with it. So just look around a little.
