object reference not set to an instance of an object--
Please help me resolving this error. Is there a mistake in my syntax?
string filename = Path.GetFileName(FileUpload1.PostedFile.FileName);
FileUpload1.SaveAs(Server.MapPath("~/Uploads/") + filename);
I am having a problem in the first line
well you have not mentioned any language and platform. But seems that you are working on asp.net here is VB code to help you.
Sub SubmitButton_Click(Source As Object, e As EventArgs)
If Not (File1.PostedFile Is Nothing) Then
Try
File1.PostedFile.SaveAs("C:\Uploads\uploadedfile.txt")
Span1.InnerHtml = "Upload Successful!"
Catch ex As Exception
ex.ToString()
End Try
End If
End Sub

This is more of general question, I suppose, as-well-as help with a specific line of code.
I have an Excel file that I was working on just a few days ago that was working fine, however now whenever I try to run the macro in the workbook to pull data from a website, I receive the error "Run-time error '380': A script engine for the specified language can not be created."
Here is the code block where I am running into the issue. I have starred the specific section where the error is thrown.
Dim H As Object, S As Object, jParse As Object, X64 As Object, i&
Set H = CreateObject("WinHTTP.WinHTTPRequest.5.1")
H.SetAutoLogonPolicy 0
#If Win64 Then
Set X64 = x64Solution()
X64.execScript "Function CreateObjectx86(sProgID) Set CreateObjectx86 = CreateObject(sProgID): End Function", "VBScript"
Set S = X64.CreateObjectx86("MSScriptControl.ScriptControl")
#Else
Set S = CreateObject("ScriptControl")
#End If
***S.Language = "JScript"***
S.AddCode "function keys(O) { var k = new Array(); for (var x in O) { k.push(x); } return k; } "
I have never seen this error before and I am not sure how to fix this issue. I have looked online and have thus far been unsuccessful in figuring out the problem. I have also tried downloading and installing the zip file from Microsoft in this link: https://gallery.technet.microsoft.com/scriptcenter/Registry-key-to-re-enable-835fba77 with no success.
Any help would be appreciated, because I really don't know what to do here.
Also if Stack Overflow is not really the place for this kind of question, any help in directing me somewhere that would be better suited for this kind of problem would be appreciated.
I just had a similar encounter attempting to use JScript to parse some JSON from the SO API using a x64 machine.
Disclaimer: I did not author the following procedures, but unfortunately I do not have the source of where I obtained them either.
As you've probably already figured out, MSScriptControl.ScriptControl doesn't like the x64 architecture very well. Here are a couple of functions that will allow you to do what you need.
I placed these in a separate module:
Public Function CreateObjectx86(Optional sProgID, Optional bClose = False)
Static oWnd As Object
Dim bRunning As Boolean
#If Win64 Then
bRunning = InStr(TypeName(oWnd), "HTMLWindow") > 0
If bClose Then
If bRunning Then oWnd.Close
Exit Function
End If
If Not bRunning Then
Set oWnd = CreateWindow()
oWnd.execScript "Function CreateObjectx86(sProgID): Set CreateObjectx86 = CreateObject(sProgID): End Function", "VBScript"
End If
Set CreateObjectx86 = oWnd.CreateObjectx86(sProgID)
#Else
Set CreateObjectx86 = CreateObject(sProgID)
#End If
End Function
Private Function CreateWindow()
Dim sSignature, oShellWnd, oProc
On Error Resume Next
sSignature = Left(CreateObject("Scriptlet.TypeLib").GUID, 38)
CreateObject("WScript.Shell").Run "%systemroot%\syswow64\mshta.exe about:""about:<head><script>moveTo(-32000,-32000);document.title='x86Host'</script><hta:application showintaskbar=no /><object id='shell' classid='clsid:8856F961-340A-11D0-A96B-00C04FD705A2'><param name=RegisterAsBrowser value=1></object><script>shell.putproperty('" & sSignature & "',document.parentWindow);</script></head>""", 0, False
Do
For Each oShellWnd In CreateObject("Shell.Application").Windows
Set CreateWindow = oShellWnd.GetProperty(sSignature)
If Err.Number = 0 Then Exit Function
Err.Clear
Next
Loop
End Function
Then you can go back to your S object and set it this way:
Dim S As Object
Set S = CreateObjectx86("MSScriptControl.ScriptControl")
S.Language = "JScript"
The last week I asked how to solve an error in an evaluate statement (Error in Evaluate statement macro).
Once fix it, I have other error with the same evaluate statement, it doesn't give me any value.
I will describe what I have and what I try.
#DbLookup in Calculate Text
I have this code into in an calculate Text and it works fine.
suc := #Trim(#Left(LlcPoliza;2));
_lkp := _lkp := #DbLookup("":"NoCache";"C1256EAD:00478951";"People2"; "D"+suc; "FullName");
#If( #IsError( _lkp ) ; " " ; _lkp );
#Name([CN];_lkp)
LlcPoliza is a document field (doc.LlcPoliza) and in a document it has for example the value C2H2H2.
The formula give first the value C2 and then look up into People2 who is D+C2 and give me a person.
It works fine.
Evaluate Statement (#DbLookup) in a Class
I have a class DirectorSucursal.
Class DirectorSucursal
Private m_branch As String
'Constructor class
Public Sub New (branch)
Dim subString As String
subString = Left(branch, 2)
me.m_branch = subString
End Sub
'Deleter Class
Public Sub Delete
End Sub
'Sub show the code about Suc
Public Sub GetCodSuc
MsgBox m_branch
End Sub
'Function get the name director
Public Function getNameDirector As String
Dim varResult As Variant
varResult = Evaluate({#DbLookup("":"NoCache";"C1256EAD:00478951";"People2"; "D} & m_branch & {"; "FullName)"})
getNameDirector = CStr( varResult(0) )
End Function
End Class
Then, in a button I instantiate the new object DirectorSucursal with the parameter of the field doc.LlcPoliza(0) like this.
Sub Click(Source As Button)
Dim director As New DirectorSucursal(doc.LlcPoliza(0))
director.GetCodSuc
director.getNameDirector
end Sub
The field doc.LlcPoliza(0) has the value C2H2H2. GetCodSuc show the value C2, but the function getNameDirector doesn't work.
It shows the error:
Operation failed
Evaluate Statement (#DbLookup) in click button
I have tried the same but into a click sub.
Sub Click(Source As Button)
Dim subString As String
subString = Left(doc.LlcPoliza(0), 2)
Dim eval As String
eval = Evaluate({#DbLookup("":"NoCache";"C1256EAD:00478951";"People2"; "D} & subString & {"; "FullName)"})
Msgbox eval
End Sub
The field doc.LlcPoliza(0) has the value C2H2H2. But it doesn't work
It shows the error:
Operation failed
My question is: what am i doing wrong? Why the code works fine in a calculate text with #Formula but with Lotusscript not?
Thanks.
EDIT 1:
I have added and Error Goto, modified the class code, modified #dblookup in calculate text and I have this error:
Error in EVALUATE macro
Please read documentation and use help! evaluate always returns an ARRAY, as stated in the help:
Return value
variant
The result of the evaluation. A scalar result is returned.
To make your code return a STRING you need to change it like this:
Public Function getNameDirector As String
Dim varResult as Variant
varResult = Evaluate({#DbLookup("":"NoCache";"C1256EAD:00478951";"People2"; "D} & m_branch & {"; "FullName")})
getNameDirector = Cstr( varResult(0) )
End Function
The CStr is just there for the case where the #DBLookup returns an error or a number (both possible)
Just a few things in general:
NEVER write even one line of LotusScript- code without error handler. It will cause you trouble FOR SURE. If you had error handling in place, then it would have told you in which line the error occured...
NEVER use the result of #DBLookup without checking for #IsError... It will cause lot of troubles when the lookup fails.
IF you use #Iserror, then don't do the Lookup twice, assign the lookup to a variable and check that one for #Iserror, like this. Otherwise performance will go down in big forms:
Example:
_lkp := #DbLookup("":"NoCache";"C1256EAD:00478951";"People2"; "D"+suc; "FullName");
#If( #IsError( _lkp ) ; " " ; _lkp )
EDIT: As Knut correctly stated in his answer the real cause for the error was a typo in the formula ( Fullname)" instead of Fullname") that I fixed in my example as well.
1) My suggestion is to never (or at least very seldom) use Evaluate() in Lotusscript. You have proper Lotusscript functionality to do almost everything.
One of the major reasons is that the code is very hard to debug (which is what you are now experiencing).
2) Don't use extended notation when you work with fields. The best practice is to use the GetItemValue and ReplaceItemValue methods of the NotesDocument class for performance reasons as well as compatibility reasons.
3) In the examples with buttons you have a reference to doc, but it is never declared or initialized in the code. If you would use Option Declare at the top of your code you would catch these kinds of errors.
4) I also reccomend against using replica ID to reference databases, that makes it very hard to maintain in the future. Unless you have a very good and convincing reason, reference them by server and filename instead.
I would suggest you refactor your code to something like this:
'Function get the name director
Public Function getNameDirector() As String
Dim db as NotesDatabase
Dim view as NotesView
Dim doc as NotesDocument
Dim key as String
Dim fullname As String
Dim varResult As Variant
Set db = New NotesDatabase("Server/Domain","path/database.nsf")
If db Is Nothing Then
MsgBox "Unable to open 'path/database.nsf'"
Exit Function
End if
Set view = db.GetView("People2")
If view Is Nothing Then
MsgBox "Unable to access the view 'People2'"
Exit Function
End if
key = "D" & m_branch
Set doc = view.GetDocumentByKey(key)
If doc Is Nothing Then
MsgBox "Could not locate document '" & key & "'"
Exit Function
End if
fullname = doc.GetItemValue("FullName")(0)
End Function
Ando of course update the button actions in the same way.
Yes, it is a few lines longer, but it is much more readable and easier to maintain and debug. And you have error handling as well.
Change your last part in #DbLoookup code line to:
"FullName")})
I'm trying to use the code in this link, but I keep getting the runtime error 438 "Object doesn't support this property or method" for the line
ActiveSheet.PivotItems(1).Visible = True
Does anyone know what's going on?
Full Code:
Sub DeleteAllFields()
Dim i As Long
ActiveSheet.PivotItems(1).Visible = True
For i = 2 To ActiveSheet.PivotItems.Count
ActiveSheet.PivotItems(i).Visible = False
Next
End Sub
Full disclosure - I am a novice VBA user.
Thank you!
The error relates to you using .PivotItems() with the object ActiveSheet.
The PivotItems() property is part of the PivotFields() object so you would need something like:
ActiveSheet.PivotTables("PivotTable1").PivotFields("Example Field").PivotItems(1).Visible = True
I'm trying to create a macro that can collect data from an excel spreadsheet in the local active workbook and then create header file which I would later incorporate into my project. But for the life of me I must be missing something so DUMB that I can't create a working function that returns a string (which would construct a C++ structure) to the calling function. I've simplified the example code to is absolute bare minimum to isolate the problem but I still cannot figure out what I'm doing wrong. I'm not an expert at VBA but I know how to create code and I can't narrow down what VBA is unhappy about. I keep getting "compile error, syntax error." Please copy the following code into your module and see if compiles properly for you. If you know where I went wrong please let me know. Much Appreciated!!!
Sub CREATE_FACTORY_SETTING_HEADER()
Dim FS, TSsource
Set FS = CreateObject("Scripting.FileSystemObject")
Dim TSout
Set TSout = FS.Createtextfile("HeaderFile.h", True)
Dim fileHeading As String
fileHeading = "File Heading for Header file"
Dim fileBody As String
fileBody = "Some initial file body lines"
fileBody = fileBody & createStructBody
TSout.Write fileHeading & fileBody
TSout.Close
End Sub
Public Function createStructBody() As String
Dim structBody As String
structBody = "Hey I'm a struct body, but I can't be returned for some reason"
Return structBody
End Function
Both VBA and VBScript use 'assignment to function' (instead of 'return' or 'result of last statement') to return results from functions. So
Public Function createStructBody() As String
createStructBody = "Hey I'm a string and can be returned."
End Function
Hi everybody and thanks in advance.
I'm trying to call a SAP BAPI using RFC from vb but I'm having some problem to get the result of the call.
The BAPI "BAPI_GL_ACC_EXISTENCECHECK" (from General Ledger Account module) has two parameters,
COMPANYCODE and GLACCT, and a RETURN parameter.
I wrote this piece of code to make the call and I had no problem to establish the SAP Connection (I use the SAP Logon Control OLE/COM object to do the job), and I tried to make the RFC call.
Also in this case I make the call without problems (it seems, not sure about it ...), because the RFC call returns true and no exception.
However, looking through the objReturn object/parameter, it has a value "Error 0" in it.
I was expecting a complex structure like the BAPIRETURN object in SAP or something similar if the account doesn't exist.
Tried to search with Google and SAP forums but I haven't found a real solution to my problem, so here I am to ask you all if you have some idea to solve this problem (maybe I'm only making a wrong call!!! I'm quite a newbie on SAP integration ...).
BTW, Final Notes: after a lot of RFC_NO_AUTHORIZATION on the SAP side, they gave me a SAP_ALL / S_RFC authorization (sort of, not a SAP expert) and the error RFC_NO_AUTHORIZATION disappeared, but not the Error 0 return

You need to put
Dim objReturn As Object
Set objReturn = objRfcFunc.imports("RETURN")
BEFORE objRfcFunc.Call
i.e. you must state what you're importing from the function before you call it. I usually put it alongside the .exports() lines.
The problem was solved, please take a look at this thread ...
