I want to write an import function for importing data from a website into a ms access database. The original data is stored in a mysql database and is available via a remote text file (csv). So all I want is to access this remote file and read it in vba. The code I use is below, but it seems that references are missing. Don't know which reference ActiveXperts.Http needs. Could anybody help?
Thx
Steve
Dim objHttp
Dim strUrl
Dim strData
' Create a HTTP instance
Set objHttp = CreateObject("ActiveXperts.Http")
' Write some information to console
MsgBox "ActiveSocket " & objHttp.Version & " demo."
MsgBox "Expiration date: " & objHttp.ExpirationDate & vbCrLf
Do
strUrl = InputBox("Enter a URL", "Input", "www.activexperts.com/products")
Loop Until strUrl <> ""
objHttp.LogFile = "C:\HttpLog.txt"
objHttp.Connect (strUrl)
If (objHttp.LastError <> 0) Then
MsgBox "Error " & objHttp.LastError & ": " & objHttp.GetErrorDescription(objHttp.LastError)
Else
strData = objHttp.ReadData
If (objHttp.LastError <> 0) Then
MsgBox "Error " & objHttp.LastError & ": " & objHttp.GetErrorDescription(objHttp.LastError)
Else
MsgBox strData
End If
objHttp.Disconnect
MsgBox "Disconnect."
End If
MsgBox "Ready."
This tutorial says that it needs ActiveSocket 2.4 Type Library.
(the tutorial is for VB 5/6 and not VBA, but the reference stuff should be exactly the same)

So I've been at days now trying to solve this bug. After having all functions for Access objects exported, removing binary data from specified fields, and importing Access objects to fresh database, this is the error I'm still having issues with.

And where an example Form text file (with the necessary data removed) is here
Where to differentiate the objects, files in cFilePath follow "\dir...\Form_FormName.txt" format, while accObjectName is just "FormName". The issue I'm having is importing Access forms.
Things I have tried:
- I have removed the "NoSaveCTIWhenDisabled =1" lines from the form files, since in old mdb formats this was causing import issues. (Even with this line on still caused import issues)
- I have also tried removing all blank lines from the text files, in case the command had issues with reading them.
While a small subset of form objects to get imported, not all of them do, resulting in this error. Checking the files themselves to see why, I can't make sense of them since the format looks relatively the same for all of them. What would be a reason for this automation error to occur? All other export/parsing functions seem to run fine...
I have this database and it was working perfect, but today it started hating me. I started getting a Compile error: Can't find project or library. I looked around and found that when using the front end on a different computer, under VBA and references, it was missing a reference for Microsoft Word 15.0 Object Library.
My computer I have the Microsoft Word 16.0 Object Library checked. How can I get this to work on other computers with 15.0 and 16.0?

Adding references to Word during development has the advantage to be able to use strongly typed word objects and thus being able to take advantage of IntelliSense. But these references are, as you have experienced, sensible to versioning. Therefore, I suggest you remove the reference to Word once development is achieved. You will also have to replace all Word-related types by Object, i.e. use late binding. This makes the application more robust with respect to versioning.
You can get an existing Word instance which is already open or open a new one with this code snippet, without any references to Word DLLs.
Public Function GetWordApplication() As Object
'Gets an active Word application or opens a new Word instance.
'Raises Error No. 8 if word cannot be opened.
On Error Resume Next
'Find existing instance of Word
Set GetWordApplication = GetObject(, "Word.Application")
If Err.Number <> 0 Then 'Not found, create new instance.
Set GetWordApplication = CreateObject("Word.Application")
End If
'Following code is optional. You can instead test for Nothing at the call site
On Error Goto 0
If GetWordApplication Is Nothing Then
Err.Raise 8, "YourApp.GetWordApplication", "Word could not be opened."
End If
End Function
I'm trying to change my application so that it outputs JSON instead of HTML when it makes an AJAX request for some data. I have an ADODB RecordSet. I need to loop through it row-by-row and add/change/remove different values. Then I need to take all the modified rows and response.write them as JSON. I'm using JSON2.asp so my application already supports JSON.parse & JSON.stringify but I can't get it to spit out the multi-dimensional array as JSON.
set rs = conn.execute(strQuery)
if Not rs.EOF Then
rsArray = rs.GetRows() 'This pulls in all the results of the RecordSet as a 2-dimensional array
columnCount = ubound(rsArray,1)
rowCount = ubound(rsArray,2)
For rowIndex = 0 to rowCount 'Loop through rows as the outer loop
rsArray(3,0) = "somethingelse"
Next 'Move on to next row if there is one
response.write JSON.stringify(rsArray) & " _______ "
End If
I just need to be able to go through the results of my database query, modify the results, and then output the modified results in JSON format. What's the right way to do this?
The JSON2.asp implementation doesn't have a "Load From Database" function which means you will have to implement something to convert the ADODB.Recordset to a JSON structure yourself.
If you are willing to use a different script there is an implementation by RCDMK on GitHub that does have a LoadRecordset() method, it's called JSON object class 3.5.3.
This makes loading data from an ADODB.Recordset really straightforward.
<!-- #include virtual="/jsonObject.class.asp" -->
<%
Response.LCID = 2057
'...
Dim rs: Set rs = conn.execute(strQuery)
Dim JSON: Set JSON = New JSONobject
Call JSON.LoadRecordset(rs)
Call Response.Clear()
Response.ContentType = "application/json"
Call JSON.Write()
%>
Code has been tested using a disconnected recordset, the ... here denote assumed code to setup your recordset, connection etc
It's worth noting you could write this yourself, it's not a huge leap to loop through an ADODB.Recordset and build a JSON string. However, I would argue against for a few reasons;
It is a time-consuming exercise.
Very easy to miss something (like checking for numeric data types, when generating output).
Depending on how it is coded can make it awkward to maintain (For example, if not injecting property names directly from the recordset and choosing to "hardcode" them instead).
Why reinvent the wheel ? There are a lot of public implementations in the wild that deal with the issues raised here. Admittedly, some are better than others, but it takes five minutes to include them and give it a try.
Just for completeness here is my local test code using a disconnected recordset
<!-- #include virtual="/jsonObject.class.asp" -->
<%
Call init()
Sub init()
Dim fields: fields = Array(Array("title", adVarChar, 50), Array("firstname", adVarChar, 50), Array("lastname", adVarChar, 50), Array("age", adInteger, 4))
Dim rs: Set rs = Server.CreateObject("ADODB.Recordset")
Call InsertRow(rs, fields, Array("Mr", "Joe", "Bloggs", 31))
Call InsertRow(rs, fields, Array("Mr", "John", "Smith", 42))
Response.LCID = 2057
Dim JSON: Set JSON = New JSONobject
Call JSON.LoadRecordset(rs)
Call Response.Clear()
Response.ContentType = "application/json"
Call JSON.Write()
End Sub
Sub InsertRow(ByVal rs, fields, values)
With rs
If rs.State <> adStateOpen Then
For Each fld In fields
Call .Fields.Append(fld(0), fld(1), fld(2))
Next
.CursorLocation = adUseClient
.CursorType = adOpenDynamic
Call .Open()
End If
Call .AddNew()
For i = 0 To UBound(fields, 1)
.Fields(fields(i)(0)).Value = values(i)
Next
Call .Update()
Call .MoveFirst()
End With
End Sub
%>
Output:
{"data":[{"title":"Mr","firstname":"Joe","lastname":"Bloggs","age":31},{"title":"Mr","firstname":"John","lastname":"Smith","age":42}]}
Here ya go. This works for me.
set rs = conn.execute(strQuery)
c=0
Response.write "["
Do Until rs.eof
'Assign variables here with whatever you need to change
title = rs(0)
fName = rs(1)
lName = rs(2)
empID = rs(3)
With Response
if c > 0 then .write ", "
.write "{" & chr(34) & "Title" & chr(34) & " : " & chr(34) & title & chr(34) & ", " & chr(34) & "FirstName" & chr(34) & " : " & chr(34) & fName & chr(34) & ", "

End With
c = c + 1
rs.MoveNext
Loop
Response.write "]"
This will write your JSON object directly to the page.

I'm making a very basic data entry and database system application using excel (for bulk data entry) and Access (to house the data). I play to distribute it as a zip file. In order for it to work I need the file structure to remain unchanged and to unzip to c:/ drive. Is there anyway to force a zip file to unzip to a specific location?
The reason I need this is to automate the uploading of entered data. As far as I know in Access VBA you have to specify full filepaths in VBA to import data.
* Update
Thanks to Remou for getting me out of the woods. Just for posterity's sake this is how I solved it. not the prettiest code but it does the job. First the import function and then the export function.
Importing, a naming convention is still need for the files being uploaded but they can come from anywhere. That file name relates to the tables they will be stored in. At the back end of the excel sheets the data input sheet is split into two (Rec and Occ)
Code as follows:

Exit Function
End If
If The_Year = 2012 Then
occNumber = 1000
ElseIf The_Year = 2013 Then
occNumber = 2000
End If

Then the export uses the names of command buttons (that match table names) to export to wherever the user wants:

'Change the year from a variant to what we need in the SQL
If The_Year Like "20*" Then

MsgBox The_Year & "Data Type = " & VarType(The_Year)
Else: The_Year = "*"
MsgBox The_Year & "Data Type = " & VarType(The_Year)
End If
'Set queryYear variable
setYear (The_Year)
'Check the variable is correct

End Function

Public Function setYear(The_Year As Variant)
queryYear = The_Year
End Function

It should be noted that the file save and file open code sections are not mine. They come from Ken Getz and the whole code can be found here:

It would be better to use the application path ( eg currentproject.Path ) or to ask the user to specify a location for the data store rather than to try to force an install at a location that may not be available to the user. There is no need at all to hard-code paths. In Access, you can store information relevant to the project in a table, including the data path. You can look up MS Access from Excel.
I have linked the sql server tables to ms access so that I can use ms access as the front end.I was able to access the tables from access, until I run into an error ODBC call failed when I tried to open one of the tables. There was no problem with the other tables. Actually I have changed a column name in sql server after creating a link. Is this the problem? I am really worried about this as I was about to use access as a front-end for my future purposes.
When you link to a remote table, Access stores metadata about that table. When you later change the table structure, the metadata doesn't get updated to capture the change.
Delete the link. Then recreate the link. That way the metadata will be consistent with the current version of the table.
Yes changing the column name after linking the table is most likely causing your failure. Is it is now trying to pull data from a column that no longer exists. You will need to relink the table. You can programatically link tables in access. We do that in may of our access applications and drive the tables that need to be linked from a local access table.

We are using a single SQLServer login for our access applications so the g_strSQLServerUID and g_strSQLServerPwd are globals that contain that info. You may need to tweek that for your own needs or integrated security. We are setting up two DSNs one for production and the other for development. The DEV_MODE global controls wich set of DSNs are linked. You can call this code from a startup macro or startup form. It will deleted the old link and create a new link so you always have the most up to date schema.
