Modules & VBA :: Retrieving Array Returned From PHP
Mar 11, 2014
I have an Access Database that I will be using on a desktop. I have a table in this database that mirrors the structure of a table on a remote server in a SQL database. I have successfully created a vba function within the Access database that uses a server-side php subroutine to select records (I usually won't know how many) from the SQL database and return them to the access database. The code I use in the access vba subroutine to access the php subroutine is:
Code:
With CreateObject("Shell.Application").Windows
Set ieWindow = CreateObject("InternetExplorer.Application")
ieWindow.Visible = False
apiShowWindow ieWindow.hwnd, SW_MAXIMIZE
ieWindow.Navigate "Web address for server-side php file"
End With
The last command in my php subroutine is "return $retrievedData." $retrievedData is a multidimensional array containing data from 42 fields in multiple records (again, I usually won't know how many). I've checked the data in php so I know it has been stored correctly.how do I access the returned data within my access vba subroutine?
I should add that my overall reason for doing it this way is that I want to maintain my server-side database as an untouched master. Users can only add data to it. My client-side database is used to update the input table and further process the data. The subroutines described above are intended to retrieve "new" records only (i.e., records posted since the last access database update) from the server-side database and transfer them to the access database for further processing.
Continuing with production of my database I've come across another wall that I'm trying to pass. My aim is when the user press the "Quit" button it will export everything to a file which is stored on Google Drive as google drive is installed on the laptops that will be using this database.
However the problem is Google drive is stored in the computer user files i.e C:UsersstudentGoogle Drive - is there a way to retrieve the name of the user that is logged into windows?
Code:
Private Declare Function GetUserName Lib "advapi32.dll" Alias "GetUserNameA" _ (ByVal IpBuffer As String, nSize As Long) As Long Private Declare Function GetComputerName Lib "kernel32" Alias "GetComputerNameA" _ (ByVal lpBuffer As String, nSize As Long) As Long Function ThisUserName() As String Dim LngBufLen As Long Dim strUser As String
[code]....
However cant get this to work - I think that is probably because i'm declaring this code in the wrong place - I've tried declaring the private functions in a class module and the functions in a module - however no success - How do you set this code up? Or is there a new way to do this?
Public Function OdometerInput(varodometer As Variant) As Long Dim varKilometres As Variant varKilometres = varodometer * 1.609344 OdometerInput = CLng(varKilometres) End Function
It works fine in the immediate window (although I haven't just fathomed what to do with null values and such) But my question which I am sure will be 'easy when you know' is how do I pass the variable to it from a text box on a form and retrieve the data in another text box on a form.
Front end Access 2010, back-end SQL-server 2008 R2.
Normally I retrieve a certain value by Dlookup("myvalue", "mytable",...)
or
strSQL = "SELECT myvalue FROM mytable...;"
Set rs = CurrentDb.OpenRecordset(strSQL, 4)
But is there any faster way to retrieve a single value from an SQL-server table, beside doing doing the select by a stored procedure running through a pass through query, then open a recordset
Set rs = CurrentDb.OpenRecordset("mypassthroughquery")
just to retrieve ONE value?
I could not find something like DLookup("...) for an SQL-Server or in T-SQL.
I have some code that successfully gathers some items and adds these items to a listbox, one item at a time using .AddItem.And it works ok.The problem is, when there are a bunch of items to add, everytime the .AddItem runs, the form redraws.there are a bunch and this leads to a lot of flicking while the form redraws however many times .AddItem adds an item.
I've had the idea of building an array and then assigning the array to the listbox.I can build the arrray no problem but i have not been able to assign the array to the listbox all at once.how to do is add items to the listbox from the array one specific item ListArray(i) at a time.
Obviously this would work, but gains me nothing in terms of the visual effect in the form becuase it is still adding to the listbox one item at a time.Is there some way to assign an array to a list box all at once, without doing it one item at a time?
How do I delete values in an array? I want to reuse that array but first I need to delete its values so I would start with Arr(0) rather than where I stopped off with the last loop at Arr(10) [assuming the last calculation inserted until Arr(9)]
Here is my code:
Set rst = CurrentDb.OpenRecordset( _ "Select * from dbo_ProductStructure where ChildProductNbr Like '*" & txtPartNumber & "*'") 'search associated fields with user input While rst.EOF = False ReDim Preserve Arr(i) Arr(i) = rst.Fields("ParentProductNbr") i = i + 1 rst.MoveNext
I'm trying to store all the OrderNumber + Item combinations in 2 arrays and then because the OrderNumber column really contains 2 values I'm interested in, I split it up and store that column's values in 2 arrays. So in total, I have 3 arrays. An array for Item, an array for Order, and an array for RepId (which is the one that I split up from the OrderNumber column).
Anyways, when I print the RepId array with the ' MsgBox PostValCol1(x) ' It prints 4 values like it's supposed to. But when I tested it again by looping through the values and just doing a MsgBox, It goes for a long time and that's because it has a lot of empty values in that array. How to get rid of those empty values/not store them in the first place?
Code:
Set rop = CurrentDb.OpenRecordset("Select OrderNumber, ItemNumber From dbo_EntryStructure Where (ProductNumber = '" & txtPartNumber & "') AND (ActionCode = 'I')")
While rop.EOF = False ReDim Preserve ArrRepOrder(j) ReDim Preserve ArrItem(j)
I have a boolean array, foundState(3), whose 4 elements correspond to 4 variables describing conditions that will dictate what action is taken upon closing a form.
There are only 6 possible outcomes for the array, and they can be divided into just 4 cases:
Case {T,T,T,T}
Case {T,T,T,F} OR {T,T,F,F} OR {T,T,F,T}
Case {T,F,F,F}
Case {F,F,F,F}
What the proper syntax would be for this if I'm trying to create a "Select Case" statement for these 4 cases.
how I can make an Array and For Each statement work together. I normally don't use either, but it would be good so I could write less code where plausible. Here is the example I have:
Code: Dim Named As Variant Dim Ctl As Control Named = Array(Me.Namee, Me.ID, Me.Title)
[code]....
I am unsure how I include the array in this statement. I have tried replacing "Me.Controls" with the array name, but I get a 424 runtime error (no object). What I am trying to accomplish is for each item in the array I want to make it not visible if it has a null value.
I have to deal with string arrays that store text. I need info on copying, comparing, appending arrays. Also on passing arrays as parameters to subs or functions. Where I can get to this info quickly without having to browse through many screens.
In addition to this I have some questions:
I have to find the duplicates of values in an array. Here is the code that I use.
Code: Sub FindDuplicates() Dim I As Integer, J As Integer, IEND As Integer, text() As String ReDim text(IEND) For I = 1 To IEND - 1 For J = I + 1 To IEND If text(I) = text(J) Then text(J) = "" Next J Next I End Sub
It works but is not performing well. Are there more efficient ways of doing this?
I'm trying to upload a csv file into an Array then add records to a table. I have the following code which gets the information from a csv file which works fine.
Open filePath For Input As #1 Do While Not EOF(1) Line Input #1, MyData
Problems: 1. When i try to load this into an array , it does not return all the information. It will if a smaller amount of data is sought. For example if only 1 months month of data is requested. Is there a maximum data limit that can be parsed into an array with this method?
2. I'm not quite sure how to parse individual lines (records) to update a table in access. I have provided the code that I'm trying to use to accomplish this below. From code below am I doing this correctly?
3. For each record that is created in the database I would like to add a ticker string to the record for later querying. Can this be done and am I on the right track from the supplied code?
Private Sub ImportData(filePath As String, ticker As String) 'On Error GoTo Errorhandler Dim arrData() As String Dim MyData As String Dim i As Integer Dim Db As DAO.Database
I've created an array that I created and declared as a Public array in my module. I created a function that populates the array so that I can use the values in another function. I've gotten the array to populate but when I go to use the values in the array in another function, the array appears at Empty. I seem to be stuck on declaring it properly or something so that it can be used by other functions.
Public arrWebIDs As String Public Function FillArray()
I have the following script which I use to modify all report settings, with an array so that I can easily list reports that I want to change the settings for, there could be 50+ reports.
I can use a string but I have to put str1 as string, str2 as string etc... whereas an array would be easier (if I knew how to do it).
Code: Public Sub ModifyAllReportsProperties() Dim obj As AccessObject, dbs As Object Set dbs = Application.CurrentProject Dim ReportName As String
Code: Public Sub AppendClause(Clauses() As String, Item As CheckBox, Column As String) Select Case True Case IsNull(Item.Value) Return Case (Item.Value = -1) Clauses.Append ("'" + Column + "'" + "=true") Case (Item.Value = 0) Clauses.Append ("'" + Column + "'" + "=false") End Select End Sub
The problem I'm having is that Clauses.Append causes a "Invalid Qualifier" error to happen. I know that error means it doesn't recognize anything within scope that has that name.. But I'm obviously defining it in the parameters.
I am having trouble checking if the last array value is equal to 'D'.
This is what i have so far but it keeps saying that 'subscript is out of range'... 'g' by the way is equal to 1. It just really means that there's only one value in ArrAC.
I am trying to send emails using CDO to an array of recipients loaded from a query. I have made this work using Lotus Notes so i know the first part of my code is correct, and the current code I have works when I input an actual email address. But when I try to add the Array name into the 'To' field I get a data mismatch error.
I'm trying to parse the following into an Array by splitting the csv file using a "," comma separator. There should be 63 different data pieces in this File. When I do a count of them from the (ubound array) i only get 54. The last data piece on each row gets concatenated to the first data piece of the next line. Is there a way to stop this from happening? This is causing problems with working with the data.
