Msvm_Keyboard 类的 TypeText 方法
模拟一系列类型化字符。 这等效于为字符串中的每个字符调用 PressKey ，后跟 ReleaseKey 。
语法
uint32 TypeText(
[in] string asciiText
);
parameters
-
asciiText [in]
-
类型： 字符串
要键入的 ASCII 或 Unicode 字符系列。 此字符串的最大长度取决于字符串中的字符类型。
字符串类型 最大字符数 ASCII 512 Unicode 256 到 512，具体取决于字符串中的代理项对数。
返回值
类型： uint32
返回值为零表示成功。 返回值 1 表示输入字符串中不可翻译字符导致的失败。 所有其他非零值表示修改密钥状态失败。
