Modules & VBA :: How To Make Array And For Each Statement Work Together
Aug 23, 2013
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 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.
I basically want an SQL statement that will search all fields of a table for a certain value. At first I thought that tihs might work.. Code:SELECT * FROM tblExample WHERE *='blah';
But it doesnt :-/
So, is there any other method of doing this? I know that I could just include each individual field name, but Im lazy - and its a big table (plus I want to use a similar query on a few other tables, so I want it to be fairly generic).
this DB should transfer records from table to another table and vice versa, somehow i cannot make the other command button works. it took me a week to figure it out what is wrong with the code.
pls help me with my DB.
Somebody out there!
ill attached the DB if someone replies my request.
Why doesent this work aa = Me.Due aa = DateAdd("m", aa, Date)
Tasklist.RowSource = "SELECT [Tasks].Staff_Name, [Tasks].Project_Title, [Tasks].Percentage_Complete FROM [Tasks] WHERE [Tasks].Date_Allocated < " & aa & " ORDER BY [Tasks].Staff_Name;"
Ive been trying to make a form that has a report list for filtering. Everything I research and do just isnt working for me. Ive followed a video about it and visited these sites.

Hi, all! I need some help. I am trying to figure out how to enable the subdatasheet in my subform. I've already told the root query to include the subdatasheet, and it works. My subform only allows datasheet view, and I've enabled the subdatasheet visible property in the subform. What am I missing? I really need it to show up. It would be SO cool if it would work. Thanks!
The user currently manual checks the Use Part? box but would I would like to automate with an update query. I have this query that needs to be updatable but has a group by and min to get the correct results. I plan to run this query by another update query to update the table, but its currently not updatable. Is there a workaround or does anyone have another scheme to go at it. Here is my current queries.
SELECT [t_BOM Part Cross].[Customer ID], [t_BOM Part Cross].[Assembly #], [t_BOM Part Cross].[Quote #], [t_BOM Part Cross].[Line #], Min([t_BOM Part Cross].[Alt Unit 1]) AS [MinOfAlt Unit 1], [t_BOM Part Cross].[Use Part?] FROM [t_BOM Part Cross] GROUP BY [t_BOM Part Cross].[Customer ID], [t_BOM Part Cross].[Assembly #], [t_BOM Part Cross].[Quote #], [t_BOM Part Cross].[Line #], [t_BOM Part Cross].[Use Part?] HAVING ((([t_BOM Part Cross].[Quote #])=[FORMS]![Parameter]![Quote #]) AND ((Min([t_BOM Part Cross].[Alt Unit 1]))>0)) ORDER BY [t_BOM Part Cross].[Customer ID], [t_BOM Part Cross].[Assembly #], [t_BOM Part Cross].[Quote #];
I have another query that I used a SUB SELECT ON THE [Alt Unit 1] but does not group the other fields to get the results but it is updatable.
SELECT [t_BOM Part Cross].[Quote #], [t_BOM Part Cross].[Line #], [t_BOM Part Cross].[Alt Unit 1], [t_BOM Part Cross].[Use Part?] FROM [t_BOM Part Cross] WHERE ((([t_BOM Part Cross].[Quote #])=[FORMS]![Parameter]![Quote #]) AND (([t_BOM Part Cross].[Alt Unit 1])>(SELECT MIN([Alt Unit 1])>0 FROM [t_BOM Part Cross]))) ORDER BY [t_BOM Part Cross].[Quote #], [t_BOM Part Cross].[Line #];
How do I make the windows default navigation work to the following:-Next record that navigates to next, but does not create a new record when at EOF. New record that creates a new record.
I've tried turning off 'Allow additions' for the form, but that turns off the 'New Record' button, so that's not right Perhaps it's me but the default way in which the navigation buttons work is strange. I would have thought the next button would only go next and wouldn't do new.
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 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.
I want to write a code for a calculated text field in a datasheet. Right now the calculated text field is just set to ="view runs" but I want it to say "0 runs" if there are no runs in that Lot (for every lot there could be 0 to many runs). Im not sure how to make my IIf statement... every run has a runID and LotID_FK which is the LotID foregin key which is where the LotID is assigned.
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
