7.如何在winRunner中用Windows的API函数
在使用该API函数前需要先加载该函数然后声明API函数，代码如下
load_dll("user32.dll");
extern int PostMessageA(in long, in long, in long, in long);
win_get_info("{class:window, MSW_class:AfxMDIFrame42, label:"!WinRunner.*"}", "handle", hWnd);
PostMessageA(hWnd, 16, 0, 0);
请在尝试以上代码的时候，保存脚本，呵呵！
8.怎样处理跟踪键盘操作？
答：下边的代码希望对你有帮助
function GetKeyStatus(in vKey){
auto pid, thread_id, win_desc, hWnd, KeyState, win_log_name, win_full_desc, focused_obj_desc;
win_desc = "{active:1}";
if (win_exists(win_desc)==0) {
win_get_desc(win_desc, "", "", "", win_full_desc);
GUI_map_get_logical_name( win_full_desc, "", win_log_name, "bla");
win_get_info(win_desc, "handle", hWnd);
pid = GetWindowThreadProcessId(hWnd, NULL);
thread_id=GetCurrentThreadId();
AttachThreadInput(pid,thread_id,TRUE);
KeyState=GetKeyState (vKey);
AttachThreadInput(pid,thread_id,FALSE);
if (KeyState < 0)
return(0); # Key is pressed
else
return (1); # Key is not pressed
}
else
return (-1); # No active window found, so cannot determine key state
}
9.WinRunner如何处理excel?
答：其实解决方法有很多，这里列举两种。
一.利用其他语言特性开发出dll提供给winrunner使用（vb,vc,delphi等）
二.在其他环境中实现，用winrunner调用
第一种我在这里不举例子了，第二种我利用vbs往excel中赋值给大家提供一种思路，代码如下：
'vbs中的代码
Dim ExcelApp
Dim itemX
if WScript.Arguments.Count < 2 then
r = msgbox("Requires 2 arguments", 48, "change_sheet")
else
dim fso
set fso = createobject("scripting.filesystemobject")
xlBook = fso.GetAbsolutePathName(WScript.Arguments(0))
xlSheet = WScript.Arguments(1)
set fso = Nothing
Set ExcelApp = CreateObject("Excel.Application")
ExcelApp.Workbooks.Open(xlBook)
Set itemX = ExcelApp.ActiveWorkbook.Worksheets.Item(xlSheet)
itemX.Activate excelApp.ActiveWorkbook.Worksheets(xlSheet).Range("A1").Select
excelapp.ActiveCell.FormulaR1C1 = "1"
excelApp.ActiveWorkbook.Worksheets(xlSheet).Range("B1").Select
excelapp.ActiveCell.FormulaR1C1 = "2"
excelApp.ActiveWorkbook.Worksheets(xlSheet).Range("c1").Select
excelapp.ActiveCell.FormulaR1C1 = "3"
ExcelApp.ActiveWorkbook.Save()
ExcelApp.ActiveWorkbook.Close(1)
ExcelApp.Quit() Set itemX = Nothing
Set ExcelApp = Nothing
end if
winrunner中的调用代码：dos_system("wscript "C:excel_sheet.vbs" "C:SheetBook.xls" "Sheet2"");
10.在WinRunner中如何实现得到transaction时间？
答：一般情况下transaction的时间只能在最后结果中得到，如何在脚本得到这个时间呢，下边的代码可以帮助你：
public transactions[];
function start_my_transaction(in transaction_name)
{
transactions[transaction_name] = get_time();
tl_step("Start transaction: "" & transaction_name & """,PASS,"Timestamp: " &
transactions[transaction_name]);
return (transactions[transaction_name]);
}
function end_my_transaction(in transaction_name)
{
auto end_time = get_time();
auto rc;
if(transactions[transaction_name] == "")
{
tl_step("End transaction: "" & transaction_name & """,FAIL,"Transaction was
never started.");
rc = -1;
}
else
tl_step("End transaction: "" & transaction_name & """,PASS,"Elapsed Time: "
& (rc = end_time - transactions[transaction_name]));
delete transactions[transaction_name];
return rc;
}
start_my_transaction("my_transaction");
wait(2);
rc = end_my_transaction("my_transaction");
pause("Elapsed time = " & rc);
