I am writingProgramDuring the process, we encountered a strange problem of no initialization.
Finally, we found that a global variable A is written in the CPP where the main function is located. Due to the loading sequence of the header file, a problem occurs when a Class B is used, some data in a is expected to be obtained, but nothing is actually 0, as if a was just initialized.
I don't know what the root cause is. I only know that it must be ex

Using QT this week, I ran into a very painful problem: when I created the dialog, I accidentally lost the wrong name. And it was discovered very late. This time the dialog box has been laid out almost, in order to change the name, hit the problem of more egg, changed the name after you can not use the switch to the slot function. The specific errors are shown below:This application failed to start because ...After a war, finally know how to change the name, the following steps:1: Change the name
The following is an analysis of tcomdatacu. cpp. This CPP is very important and should be analyzed several times. This is the analysis of tcomdatacu. cpp (1 ).

Recently I want to do something about real-time transmission, so I want to get a jrtplib and lthread.I discovered this was hard to find and install.Resources are available on csdn (only resource points are used). However, I do not recommend that you use these resources. After all, not all users have csdn accounts. Even if you have an account, you may not have resource points, I will give you an address. The above resources are free of charge, and they are very good (in this case, it is much bett

SuSEPost 1:Recently fascinated by swimming and QT, alive. But the QT program is built under SuSE, and the makefile that are automatically created with the steps in the QT documentation are not compiled. So my first reaction is to upgrade QT to 3.2, but after the upgrade but still can not compile, think not its solution, so patiently down to see the error message after make, and tracking to QT code inside see, found the error place is a C + + keyword place, and execute make after the first sente

Observer mode. cpp: defines the entry point of the console application
1. The so-called observer mode is the same as standing guard. As long as the notification is received, the corresponding notification will be sent.
2. Applications include Message notification mechanisms such as windows and QT. In fact, the Message notification mechanism is also the observer mode.
3. Example: in A company, there is A boss A, and then the company's employees go to w
