winform小记

FormBorderStyle:None让边框消失

private int time = 5;//停止五秒 //计时器 private void timer1_Tick(object sender,EventArgs e) { if (time!=0) { time; } else { this.timer1.Stop(); UserThisFunction(); } } 让程序停止几秒，我是这样做的。如果用线程的sleep方法的话，UI会不出来

System.Environment.Exit(0); winform关闭程序

RegistryKey keyroot = Registry.ClassesRoot;
??????????? string flashkey = @"CLSID{D27CDB6E-AE6D-11cf-96B8-444553540000}";
??????????? RegistryKey rkFlash = keyroot.OpenSubKey(flashkey);
??????????? if (rkFlash == null)
??????????? {
??????????????? //System.Diagnostics.Process.Start(Application.StartupPath + "flash10.exe");

??????????????? DialogResult dialog = MessageBox.Show("检测到您的电脑没有安装flash player，现在是否去官方下载所需插件？","检测提示",MessageBoxButtons.YesNo,MessageBoxIcon.Information);
??????????????? if (dialog == DialogResult.Yes)
??????????????? {
??????????????????? System.Diagnostics.Process.Start("http://get.adobe.com/cn/flashplayer/");
??????????????? }
??????????????? else
??????????????? {
??????????????????? Application.Exit();
??????????????? }
??????????? }
??????????? else
??????????? {
??????????????? frmMain f = new frmMain();
??????????????? this.Hide();
??????????????? Application.DoEvents();//中间加这句
??????????????? f.ShowDialog();
??????????? }

winform检测是否安装了flash

??????????? RegistryKey keyroot = Registry.ClassesRoot;
??????????? string flashkey = @"CLSID{D27CDB6E-AE6D-11cf-96B8-444553540000}";
??????????? RegistryKey rkFlash = keyroot.OpenSubKey(flashkey);
??????????? if (rkFlash == null)
??????????? {
??????????????? System.Diagnostics.Process.Start(Application.StartupPath + "flash10.exe");
??????????? }

flash player安装文件放在bin目录下
