How to kill process from LN

I found this approach as very good for my purposes. It works at least . I suppose that there are another couple even better approach, so if you know them share please.

Type PROCESSENTRY32

dwSize As Long
cntUsage As Long
th32ProcessID As Long
th32DefaultHeapID As Long
th32ModuleID As Long
cntThreads As Long
th32ParentProcessID As Long
pcPriClassBase As Long
dwFlags As Long
szexeFile As String * 260
End Type
'-------------------------------------------------------
Declare Function OpenProcess Lib "kernel32.dll" (Byval dwDesiredAccess As Long, Byval blnheritHandle As Long, Byval dwAppProcessId As Long) As Long
Declare Function ProcessFirst Lib "kernel32.dll" Alias "Process32First" (Byval hSnapshot As Long, uProcess As PROCESSENTRY32) As Long
Declare Function ProcessNext Lib "kernel32.dll" Alias "Process32Next" (Byval hSnapshot As Long, uProcess As PROCESSENTRY32) As Long
Declare Function CreateToolhelpSnapshot Lib "kernel32.dll" Alias "CreateToolhelp32Snapshot" (Byval lFlags As Long, lProcessID As Long) As Long
Declare Function TerminateProcess Lib "kernel32.dll" (Byval ApphProcess As Long, Byval uExitCode As Long) As Long
Declare Function CloseHandle Lib "kernel32.dll" (Byval hObject As Long) As Long


Public Sub KillProcess(NameProcess As String)
Const PROCESS_ALL_ACCESS = &H1F0FFF
Const TH32CS_SNAPPROCESS = 2&
Dim uProcess As PROCESSENTRY32
Dim RProcessFound As Long
Dim hSnapshot As Long
Dim SzExename As String
Dim ExitCode As Long
Dim MyProcess As Long
Dim AppKill As Boolean
Dim AppCount As Integer
Dim i As Integer
Dim WinDirEnv As String

If NameProcess <> "" Then
AppCount = 0

uProcess.dwSize = Len(uProcess)
hSnapshot = CreateToolhelpSnapshot(TH32CS_SNAPPROCESS, 0&)
RProcessFound = ProcessFirst(hSnapshot, uProcess)

Do
i = Instr(1, uProcess.szexeFile, Chr(0))
SzExename = Lcase$(Left$(uProcess.szexeFile, i - 1))
WinDirEnv = Environ("Windir") + "\"
WinDirEnv = Lcase$(WinDirEnv)

If Right$(SzExename, Len(NameProcess)) = Lcase$(NameProcess) Then
AppCount = AppCount + 1
MyProcess = OpenProcess(PROCESS_ALL_ACCESS, False, uProcess.th32ProcessID)
AppKill = TerminateProcess(MyProcess, ExitCode)
Call CloseHandle(MyProcess)
End If
RProcessFound = ProcessNext(hSnapshot, uProcess)
Loop While RProcessFound
Call CloseHandle(hSnapshot)
End If
End Sub

'Input Enabled' formula does not export in DXL using native exporter

Today we faced with funny problem in LN 6.5.4 (I'm sure the same behavior in any another version of 6.5.X)

We do export of some LN elements and when we import it back we discovered that Input Enabled formula disappear. I checked our DXL file and found that formula was non there. Then I used simple way to check where was the problem, I create simple form, put there 1 field with Input Enabled formula and using Tools\DXL Utilities\Exporter export it to file. There was no Input Enabled formula at all. Funny issues but now we have to rewrite some places.

FYI: This works correct in R7 and ++

isNumeric for web

as I think the best approach to check value in web for IsNumeric is:
function IsNumeric(inputVal,sErrorMsg) {
if (isNaN(parseFloat(inputVal))) {
alert(sErrorMsg)
return false;
}
return true
}

I also used such approach, but I don't like it anymore
function IsNumeric(expression) {
var nums = "0123456789";
if (expression.length==0)return(false);
for (var n=0; n <>
if(nums.indexOf(expression.charAt(n))==-1)return(false);
}

return(true);
}

overload of methods/functions in Lotus Script

I make overload for any methods/functions using next approach. It is quite simple and useful from my point of view

Sub new(key As Variant)
Select Case Typename(key)
Case "STRING":
call newForString(key) or do code
Case "NOTESDOCUMENT
call newForNotesDocument(key) or do code
Case "EMPTY
call newForEmpty(key) or do code
End Select
