postmessage说明（postmessage说明）
postmessage说明（postmessage说明）Keyboard is a very important input device for our computer. Even today, the mouse is popular, many programs still can not do without keyboard operation. But sometimes, some repetitive, tedious keyboard operation will make people tired, so there is a method with a program to replace the key people, so you can put a lot of repetitive keyboard operation to the program to simulate, save a lot of energy, the wizard button is a software that. So how can we write a program with VB to achieve the function similar to the button Sprite? So let's first get a look at the mechanism that responds to keyboard events in windows.When the user presses a key on the keyboard, the chip in the keyboard detects the action and sends the signal to the computer. How do you tell which one is pressed? All keys on the keyboard have a code called keyboard scan code. When you press a key, the scan code of this key is passed to the system. Scanning code is related to the specific hardware, the same key, scanning code on different keyboards may be different. The keyboard controller transfers the scan code to the computer, and then gives it to the keyboard driver. The keyboard driver completes the work and converts the scan code to the keyboard virtual code. What is virtual code? Because the scanning code is related to hardware, it is not universal. In order to unify all keys on the keyboard, the concept of virtual code is put forward. No matter what keyboard, the virtual code of the same key is always the same, so that the program can recognize it. Simply put, the virtual code is what we can often see like VK_A, VK_B such constants, such as key A virtual code is 65, written in 16 hexadecimal is &H41, note that people often use 16 binary to represent virtual code. When the keyboard driver converts thescan code to virtual code, it will transfer the scan code of the keyboard operation with the virtual code and other information to the operating system. The operating system then encapsulates the information in a message and inserts the keyboard message into the message queue. Finally, if no accident, the keyboard message final will be sent to the currently active window where the application window is to receive this message, you know which button on keyboard is pressed, it can make the decision of what response to the user. This process can be represented as follows:The user presses the button the keyboard driver transfers the event to the operating system the operating system inserts the keyboard event into the message queue the keyboard message is sent to the current active windowUnderstand this process, we can programming to achieve a link in which to simulate the keyboard operation. In VB, there are a variety of ways to implement keyboard simulations, and we'll introduce several typical ones.1. local level simulationFrom the above process, it can be seen that the keyboard event is finally sent to the active window before it causes the target program to respond. So the most direct way to do this is to forge a keyboard message directly to the target program. Haha, this is really very simple, windows provides several such API function can be achieved directly to the target program to send the message function, commonly used with SendMessage and PostMessage, the difference between them is the PostMessagefunction directly to the message to the target program is still on the matter, and send out SendMessage news, but wait for the goal of the program was to return what is good. Here we must note that analog keyboard message must use the PostMessage function to use, SendMessage is not correct (because analog keyboard message is not required to return a value, or the target program will not respond), remember! The VB declaration of the PostMessage function is as follows:Declare Function PostMessage Lib "user32" Alias "PostMessageA" (ByVal hWnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As LongThe parameter hWnd is the destination of the message you want to send a program on the handle of the control, the parameter wMsg is the type of message that you want to send what kind of message, finally wParam and lParam these two parameters are added with the message data, specific content by news decision.Let's look at the wMsg parameter, which is the key to the analog button. Keyboard messages are commonly used as follows:WM_KEYDOWN indicates that a common key is pressedWM_KEYUP indicates that a common key is releasedWM_SYSKEYDOWN indicates that a system key is pressed, such as the Alt keyWM_SYSKEYUP indicates that a system key is released, such as the Alt keyIf you're sure you want to send more than one keyboard message, then look at how to determine the two parameters of wParam and lParam in keyboard messages. In a keyboard message, wParam the meaning of the parameters is relatively simple, it represents the key code of virtual keyboard events you want to send, for example you want to target simulation press A key, then the value of the wParam parameter is set to VK_A for lParam, this parameter is more complicated, because it contains more information in general, it can be set to 0, but if you want your simulation more realistic, it is recommended that you still set the parameters. Well, let's get a little more detailed about lParam. LParam is a parameter of type long, it takes 4 bytes in memory, written in binary is 0000000000000000 0000000000000000 total is 32, the number of us from right to left, the right to assume the zeroth (note that it is not from the 0 start counting from 1), the left is thirty-first, then the parameter the 0-15 said the key to send times of extensive information, the 16-23 bit is the key scan code, 24-31 said is to press the key or key release. We generally used written 16 hexadecimal, then it should be 000000 &H00, the 0-15 is generally &H0001, if it is to press the button, then 24-31 is &H00, the release button is &HC0, then the 16-23 scan code do? This requires the use of a API function MapVirtualKey, this function can be transformed into a virtual code scan code, or the scan code into virtual code, virtual code can also be converted to the corresponding character ASCII code. Its VB statement is as follows:Declare Function MapVirtualKey Lib "user32" Alias "MapVirtualKeyA" (ByVal wCode As Long, ByVal wMapType As Long)As LongThe parameter wCode is to be converted to wMapType code, said from what parameters conversion why, if it is a virtual code to scan code, wMapType is set to 0, if the virtual scan code to virtual code, wMapType is set to 1, if it is a virtual code to ASCII code, wMapType is set to 2. believed the US. You can lParam the structure parameters of keyboard events. A function to construct lParam parameters is given below:Declare Function MapVirtualKey Lib "user32" Alias "MapVirtualKeyA" (ByVal wCode As Long, ByVal wMapType As Long) As LongFunction MakeKeyLparam (ByVal VirtualKey As Long, ByVal flag As Long) As LongThe parameter VirtualKey represents the virtual code of the key, and the flag represents the press key or the release key, and is represented by the two constants of WM_KEYDOWN and WM_KEYUPDim s As String24-31 bits of Dim Firstbyte As String'lparam parameterIf flag = WM_KEYDOWN Then 'if it is a press keyFirstbyte = "00""ElseFirstbyte = "C0" if it is the release keyEnd IfDim Scancode As Long'get the key scan codeScancode = MapVirtualKey (VirtualKey, 0)16-23 bits of Dim Secondbyte As String'lparam parameter,即虚拟键扫描码secondbyte =右（“00”与六（扫描码），2）S = firstbyte和secondbyte与“0001”“0001为lParam参数的0-15位，即发送次数和其它扩展信息makekeylparam = Val（”&“& S）端功能这个函数像这样调用，比如按下一键，那么lParam = makekeylparam （vk_a，wm_keydown），很简单吧。

夏普复印机打印机常用代码故障解决大全
夏普复印机打印机常用代码故障解决大全夏普AR205复印机显“L4-11”故障解决方法对应机型：夏普AR205、AR160、AR255、AR275和AR276皮带有移位器的机型。
故障现象： 1、主板供电不正常。
2、移位器原位传感器不正常。
解决方案：由于当时手边没有维修技术资料，照常理显示L4一般与主电机有关或者电机负载过大，于是把主电机负载减压，试机没有好转，再把主电机换一个，故障现象依旧，于是代换主电机连接电缆线，故障还是同样。
怀疑是复印机主板坏了，建议用户把主板换了后，似乎可以了，结果问题还是没有解决。
维修陷入困境，上中国维修网查阅资料得知：L4-11并不是主电机故障代码，而是移位器电机动作不正常的代码。
用-11代码检查后重回客户处。
在客户处再用-11代码检查，移位器动作不正常，为了区别故障部位，首先代换移位电机，故障依旧，主板已经代换过了，所以怀疑故障在移位器上，于是把后盖和右侧盖拆开取下移位器检查，发现移位器的导杆油污较重，于是用酒精球清洁后，再上质量较好的润滑油，上机试机，一切正常。
总结：原来故障如此简单，却走了那么多弯路，这只说明了一点，我们的技术没有得到及时更新以及没有及时的掌握，希再努力。
夏普AR275显示“F5-02”处理方法故障现象：夏普AR275复印机显示F5-02故障代码。
故障原因： 1、曝光灯损坏。
2、曝光灯线束不良。
3、电路板损坏。
解决方案：针对第一种故障原因，先接[#]键→插入键→[C]键→插入键进入模拟代码方式，执行代码5-3检查曝光灯是否工作正常，一般情况下曝光灯出现损坏的情况很少见。
接下来再检测曝光灯和电路板连接之间的线束，用万全表检测通断，再确认一下曝光灯到电路板之间的接插是否正常，如果线束不良，则更换线束。
一般出现F5-02普通都是线束不良引起的。
电路板出现损坏的情况很少，但不排除。
如果线束和曝光灯检测都正常的情况下，建议更换电路板，线束不良的原因主要是长期的磨损，定期检测线束是否扭曲，变形是防止出现F5-02故障的关键。
