If Vec contains a pointer to some some structure, then eax is assigned a copy of the first attribute of that structure. To assign a copy of the second attribute of that same structure to ebx, follow...
I am sure the term "procedure" is being used loosely. It just means a function that does not return a value, that is, the return type is void. Of course, a class method is also a function.
What is CPP?
What is BitPlanes? This should be 1.
Unless CPP is 32, BMPInfo.bmiHeader.biSizeImage is miscalculated.
Why do you set BMPInfo.bmiHeader.biClrUsed to 24? This is saying that you want...
The only way to learn to program is to actually write programs. If you have the source code for something, you still need to try it to see if it does what you think it does. A lot of times you may...
A process is an instance of an executable or application. If you have multiple instances of the same executable running at the same time, each instance is its own process. The process includes all...
Optimizers are known for switching the order of instructions in order to make things run faster. However, this switching should only occur if it does not affect the outcome of the instructions. ...
I have never used Python so I do not know anything about it. I mainly use C++. It is sort of in the middle in terms of programming languages. It is not tedious like assembly language, but at the...
Any program that does anything will use more memory than the size of the executable file. First, that executable file is loaded into memory. Then any DLLs that the process uses are also loaded into...
If you have Microsoft Visual Studio installed and an application crashes due to an access violation or invalid machine instruction, you will be asked if you want to start the debugger that comes with...
Instead of using your iPhone to take pictures of your monitor, you could press Ctrl-Alt-Print Screen, which copies the contents of the current window into the clipboard. From there you can paste it...
Should I assume that you just want to know how to do this for curiosity's sake? You do not want to steal anyone's code or do anything malicious, right? You just want to peak under the "hood"? All...
If you want to learn C++, you need to understand the syntax of the language. These are simple errors that even a beginner should be able to find and fix easily.
If your compiler does not support an API function, you can always use LoadLibrary() and GetProcAddress() to get the address of the function dynamically. The following test program shows how this is...
Your while loop will be executed only one time at most, since you are breaking out of it under both conditions of the if statement. Breaking out of loops is also considered to be sloppy coding...
Use the GetParent() function to get the window handle of the dialog box's parent. Then use the GetWindowLongPtrW() as before to get the pointer to your App instance. There is also a...
From my experience, GetWindowRect() always sets the left and top members of the RECT structure variable to 0, so subtracting them would not be needed. If this assumption bothers you, then you can...
RECT is a structure. When you pass a structure variable to a function in C++, you need to pass a pointer/reference to that variable. GetWindowRect() takes two arguments, a window handle and a...
