Objective:
Report as a major focus of the computer room charge system, its main process is divided into report design-database connection-VB and report interaction. Let's look at the report design first.
1. First download the installation Report Designer, it is commonly used by grid++report5.0

Add corresponding parts in VB
2. Open the Editor--insert a report header--Insert a static box t
table into a table in fact, there is a transitive dependency, separate is right. Design Database: The basic thing is to pay attention to the data type. This still needs to look at the code, my first version of the system d all the date and time. are all used for datetime data types. Be sure to see if there is a problem in the vb.net. In conclusion, we must learn to apply our knowledge, I learn the database is too shallow, very much or based on the original database. But I believe that when we

Calculation Formula of capacitor charge discharge time
Set, V0 as the initial voltage value on the capacitor;V1 is the final charged or placed voltage value of the capacitor;VT is the voltage value of the capacitor at t time.Then,Vt = "V0" + (V1-V0) * [1-exp (-T/RC)]Or,T = rc * ln [(V1-V0)/(V1-Vt)]
For example, a battery with a voltage of E is charged to a capacitor C with a initial value of 0 through R.V0 = 0, V1 = E, so the voltage charged to

Q: Does red rice 4 support fast charging?A: At present, many thousand yuan machines are beginning to support fast charging, such as 360 mobile phone N4A and Cool1, while red rice 4 is equipped with A 5 V/2A charger, which is A standard charger, it is a pity that quick charge is not supported.Red Mi 4 charger close-up (5 V/2A)Although red rice 4 does not support fast charging, it has a relatively mature integrated metal body design, with mainstream Qua
How long is the charge time of the notebook battery good?There is a power indicator in the lower right corner of the notebook, if you do not use the power battery can maintain 2 to 3 and a half minutes, the specific performance of different notebook, at the same time the operation also has an impact on the use of batteries, such as: watching movies, listening to songs.No electricity in the notebook, how long does the battery

A few days ago power outage, electricity used to forget to flush, put on the battery on the power cord must be pulled down and then plugged in to boot, a little power is not charged. Plug in the battery display project unknown, why the battery is unable to charge.
There are three reasons why the battery is out of order, the power adapter is faulty, and the power module on the laptop motherboard is faulted. First, eliminate the source of the fault, un
Can pirated Win7 systems be upgraded to WIN10 free of charge? According to Microsoft earlier, in Win10 officially push, piracy win7/8.1 users can not upgrade free of charge, even if you receive upgrade prompts, upgrade process will also terminate the upgrade. In addition, Tencent, 360 and Microsoft to cooperate free upgrade win 10 also does not support pirated users. Even if the upgrade succeeds Win10 will
In fact, if you encounter the above problems, you should be able to refer to the Power Management mode settings are appropriate.
If you want the battery to be full of electricity, you should set the Power management mode to "maximum endurance time."
The method is as follows:
Start-> The Control Panel, locate the "power" option, and double-click to open (figure I). Then click the Setting button in the middle of the lower right corner (figure II), and you can see two power management modes (fig
IPhone5S is using a metal shell, this is particularly easy to leakage, while it is possible to use parallel imports iphone5s, this may be even greater.
IPhone5S Why will there be charging leakage? Some engineers believe that this is because the iphone5s to the internal circuit is not fully shielded, resulting in a partial current leakage to the full metal shell. This is also the whole metal shell design of the mobile phone to face the main problem.
What is the cause of the leakage of the

Computer room charge system has been carried out for a period of time, knocked over three layers, and then overturned the knock write seven layers. There is not much time to take out every day, so the project has been on for a long time. In the process of completion, the most difficult to start knocking out a line, a variety of check data, tune code, fortunately, the code in the difficulties and errors finally in the effort to conquer.
