Windows programming is a program that completes a clock

First of all, let's introduce the method of deleting the stubborn update folder in the win2000 system (the method is similar to the winxp win2k3 system).

Folder Properties -> Security -> Advanced -> Owner -> Select Current Administrator User -> Replace the owner of the subcontainer and object.

After confirmation. That is, you can delete the update folder directly.

Due to the problem of NTFS folder permission setting, the above problems cannot be deleted by various tools to shred files, as well as in safe mode, and the above method is only tested for your reference.

In addition, I would like to add that some friends have no security options in the system right-click, if so, you can look at the "View" option in the "Folder Options", check the "Use Simple File Sharing to Tick the (Recommended)" button in front of it!

Less accurate timing cases can be timed with the SetTimer, while the clock can be achieved with GDI plotting.

"Windows Programming" is a very specific and basic book, which will be useful as a long-term reference, but it is very difficult to learn linearly, in fact, even people who have been writing Windows programs for a few years may not be able to memorize the DIB bunch. Some people may say: This is called not seeking to understand.

But this kind of understanding is not necessary at all, just use it to check it again, and if you are stumped by something at the bottom, you don't want to go up.

Nowadays, using graphics, whether it is using GDI+, or using existing graphics processing libraries, or using DIBs packaged by others, is much easier to understand than using native APIs. The DIB set is just a detail in terms of image format, and I recommend that LZ stop at it when reading this book, and then look through it later when you need the details.

Now that you've read it, you can write something yourself. When it comes to programming, writing is the fastest time to learn. However, I feel that the native API is really painful, and LZ can try other Windows development methods after this (after all, you already have a basic worldview of Windows programming), such as MFC or simply learn C, the advantage of these two is that it has a high degree of compatibility with Microsoft itself, and it is easy to use VS that set of things, and the environment is easy to match.

In addition, the most useful C++ development tool is QT, but it is cross-platform, which means that it is far away from the native WindowAPI.

"zhangfan!";

The name of the window class is stated here.

hwnd=createwindow("hello win","My window"

What is Hello Win? You didn't sign up for this window class, did you?

Hello win changed to zhangfan!Can.

Give up MFC, Microsoft doesn't use it itself.

1 All this ......I don't know how to operate the graphical interface yet, but the function that calls the system time is time(time h*) You can find another god, sorry.

This is a structured array, and initializes the array. This is equivalent to calling struct multiple times

devcaps[0]=；

devcaps[n-1]=；
