Gets the value from a control.
Description
Returns the date and time in the Value property of the control.
Applies to
DatePicker control

Argument |
Description |
|---|---|
|
controlname |
The name of the control for which you want to get the date and time |
|
d |
The date value in the Value property returned by reference |
|
t |
The time value in the Value property returned by reference |
|
dt |
The DateTime value in the Value property returned by reference |
Return value
Integer.
Returns 1 for success and one of the following negative values for failure:
-1 -- Invalid date and/or time values
-2 -- Other error
Usage
The GetValue function can return the date and time parts of the Value property in separate date and time variables or a single DateTime variable.
Examples
In this example, the GetValue function is called twice, once to return separate date and time values and once to return a DateTime value. The values returned are written to a multiline edit control:
date d time t datetime dt integer li_ret1, li_ret2 li_ret1 = dp_1.GetValue(d, t) li_ret2 = dp_1.GetValue(dt) mle_1.text += string(d) + " ~r~n" mle_1.text += string(t) + " ~r~n" mle_1.text += string(dt) + " ~r~n"

Description
Gets the value of the key. The key item must be a string, object, or array.
If more than one key with the same name exists, then get the value of the first key. Notice that the IgnoreCase property (true by default) determines whether the key name will be matched in a case-sensitive manner.

Argument |
Description |

|
objectname |
The name of the JSONPackage object |

Key |
A string specifying the key. If more than one key with the same name already exists, the value of the first key will be obtained. |
Return value
String. Returns the key value if it succeeds. If any argument's value is null, the method returns null. If an error occurs, throw the exception.
Examples
This example gets data from the server and then imports the data to the DataWindow, DataStore and DataWindowChild controls:
int li_rc
string ls_JsonPackage, ls_DepartmentJson, ls_EmployeeJson, ls_DeptJson
datastore lds_employee
datawindowchild ldwc_dept
HttpClient lnv_HttpClient
JsonPackage lnv_package
lds_employee = create datastore
lds_employee.dataobject = "d_employee"
dw_employee.getchild("dept_id", ldwc_dept)
lnv_HttpClient = create HttpClient
lnv_package = create JsonPackage
// Request JSON data package from the server
li_rc = lnv_HttpClient.SendRequest("GET", "http://demo.appeon.com/PB/webapi_client/employee/102")
// Get the data
if li_rc = 1 and lnv_HttpClient.GetResponseStatusCode() = 200 then
lnv_HttpClient.GetResponseBody(ls_JsonPackage)
// Extract the JSON data package
lnv_package.LoadString(ls_JsonPackage)
ls_DepartmentJson = lnv_package.GetValue("d_department")
ls_EmployeeJson = lnv_package.GetValue("d_employee")
ls_DeptJson = lnv_package.GetValue("dddw_dept")
// Import data to DataWindow, DataStore and DataWindowChild
dw_department.ImportJson(ls_DepartmentJson)
lds_employee.ImportJson(ls_EmployeeJson)
ldwc_dept.ImportJson(ls_DeptJson)
