利用WM5 實現(xiàn)電話功能
在程序中進行電話撥號
“項目”—“添加引用”—“Microsoft.WindowsMobile.Telephony”—“確定”
Imports Microsoft.WindowsMobile.Telephony
Private Sub Button1_Click(ByVal Sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim TestPhone As New Phone
TestPhone.Talk("1001")
End Sub
pashload是應(yīng)用在linux下的網(wǎng)絡(luò)帶寬測試源程序精確度比較高
/////////////////////////////////////
Pathload is a tool for estimating the available bandwidth
of an end-to-end path from a host S (Sender) to a host R (receiver).
The available bandwidth is the maximum IP-layer
throughput that a flow can get in the path from S to R,
without reducing the rate of the rest of the traffic in the path.
MD5變換動態(tài)鏈接庫文件調(diào)用：（delphi例子）
=========================================================================
function transfer(tran:widestring):widestring stdcall external md5.dll name transfer
//edit1為輸入字符，edit2為輸出md5摘要
procedure TForm1.Button1Click(Sender: TObject)
begin
edit2.text:=transfer(edit1.Text)
end
procedure senddata
var
i:integer commflg : Boolean
begin
commflg:=true
for i:=1 to 8 do
begin
if not fcomm comml writecommdata(sendbutter,i) then
begin
Commflg=false
break
end
end
end
(4) 接收數(shù)據(jù)
在編寫基于串口的計算機工業(yè)測控時，通常需要由下位機向PC機發(fā)送數(shù)據(jù)以使PC機了解系統(tǒng)的測試數(shù)據(jù)或下位機的運行狀態(tài)，并進而控制下位機的行為。利用Spcomm串口控件接收下位機發(fā)送的數(shù)據(jù)信息的示例代碼如下：
//事件驅(qū)動方式接收數(shù)據(jù)程序
procedure TForm1.CommlReceiveData(Sender:Tobject Buffer:Pointer bufferLength:Word)
var
receivedata:array of byte
begin
sleep(100) //等待100ms，保證接收到所有數(shù)據(jù)
move(buffef ,receivedata,bufferlength)
//將接收緩存區(qū)中的數(shù)據(jù)轉(zhuǎn)移到數(shù)組中
……
end
(5) 關(guān)閉串口
在系統(tǒng)開發(fā)中，應(yīng)注意在不使用串口時應(yīng)及時關(guān)閉串口，釋放系統(tǒng)資源，否則可能會影響系統(tǒng)的其它應(yīng)用。關(guān)閉串口的代碼如下：
procedure TForm1.FormClose ( Sender TObj ect:var Action:TCIoseAction )
begin
comml.StopComm
end
