例子
package main
import (
"github.com/lxn/win"
"strconv"
"syscall"
)
func _TEXT(_str string) *uint16 {
return syscall.StringToUTF16Ptr(_str)
}
func _toString(_n int32) string {
return strconv.Itoa(int(_n))
}
func main() {
var hwnd win.HWND
cxScreen := win.GetSystemMetrics(win.SM_CXSCREEN)
cyScreen := win.GetSystemMetrics(win.SM_CYSCREEN)
win.MessageBox(hwnd,_TEXT("屏幕长-:"+_toString(cxScreen)+"宽:"+_toString(cyScreen)),_TEXT(" 消息http://blog.csdn.net/songbohr"),win.MB_OK)
}
唯一的就是有一个win这个go module里有一个坑，在phd.go 中
func init() {
// Library
libpdhDll = syscall.MustLoadDLL("pdh.dll")
// Functions
pdh_AddCounterW = libpdhDll.MustFindProc("PdhAddCounterW")
pdh_AddEnglishCounterW = libpdhDll.MustFindProc("PdhAddEnglishCounterW") // XXX: only supported on versions > Vista.
pdh_CloseQuery = libpdhDll.MustFindProc("PdhCloseQuery")
pdh_CollectQueryData = libpdhDll.MustFindProc("PdhCollectQueryData")
pdh_GetFormattedCounterValue = libpdhDll.MustFindProc("PdhGetFormattedCounterValue")
pdh_GetFormattedCounterArrayW = libpdhDll.MustFindProc("PdhGetFormattedCounterArrayW")
pdh_OpenQuery = libpdhDll.MustFindProc("PdhOpenQuery")
pdh_ValidatePathW = libpdhDll.MustFindProc("PdhValidatePathW")
}
PdhAddEnglishCounterW这个api只在vista以上版本支持，所以如果在xp下运行，在载入时会因找不到该函数的地址崩溃，临时解决方案，暴力注释掉
//pdh_AddEnglishCounterW = libpdhDll.MustFindProc("PdhAddEnglishCounterW") // XXX: only supported on versions > Vista.

初步感觉用go写win gui，是个没意思的事！
