请教一下,在delphi的程度当中,如何模拟tab键.而系统的tab键功能不能用!
谢谢!!~
按完之后失效,又怎么做呢.!!!或者加上其他的键比如alt,ctrl
参考下这个，获得某键的状态
The GetKeyState function retrieves the status of the specified virtual key. The status specifies whether the key is up, down, or toggled (on, off ?alternating each time the key is pressed).
SHORT GetKeyState(
int nVirtKey // virtual-key code
);
Parameters
nVirtKey
Specifies a virtual key. If the desired virtual key is a letter or digit (A through Z, a through z, or 0 through 9), nVirtKey must be set to the ASCII value of that character. For other keys, it must be a virtual-key code.
If a non-English keyboard layout is used, virtual keys with values in the range ASCII A through Z and 0 through 9 are used to specify most of the character keys. For example, for the German keyboard layout, the virtual key of value ASCII O (0x4F) refers to the "o" key, whereas VK_OEM_1 refers to the "o with umlaut" key.
Return Values
If the function succeeds, the return value specifies the status of the given virtual key. If the high-order bit is 1, the key is down; otherwise, it is up. If the low-order bit is 1, the key is toggled. A key, such as the CAPS LOCK key, is toggled if it is turned on. The key is off and untog
