Looping Through Access Tables And Creating Separate Spreadsheets For Each Table?
Aug 15, 2011
I have produced some VBA in Access that creates a spreadsheet.I have also created an SQL query that retrieves records from an Access table.I have 48 tables (each table for a specific institution centre).I have created another bit of VBA code that creates a spreadsheet and loads the records from the query in to the spreadsheet.Each centre has a unique Sequence Number (Indent Number)At the moment though, all I can do is import one table (records for one institution) in to a spreadsheet. I want to end up with calling the function and having an output of 48 spreadsheets being saved to my desktop, each spreadsheet containing records of a different center.I have thought about putting a loop in, but not sure how I would quite go about it.
Here is my code to create the spreadsheet:
Public Sub ExcelExport(lngIndentNumber As Long, strFolder As String, strCrit As String, strReport As String)
', ctlLabel As Label,
DoCmd.SetWarnings False
I'm getting this error 'column' argument cannot be null. Parameter name: column at the bold character instruction. Also I would like to know how to relate two tables with two key columns in each table
Dim connection As New OleDb.OleDbConnection(strTextoConn) Dim EnPartesdataSet As DataSet = New DataSet("Enpartes") Dim strsql As String
How would I do this? I have no code at this time for it, but how could I do this?
I have an Inventory table that contains a lot of Trash Containers (Construction Dumpsters).
All of these containers have a field in the table for their "Size". If I wanted to quickly change all of the price for all Trash Containers that have a Size "40", how could I loop through the table and for each container that has a size of "40", I want to change the price lets say from $100 to $120.
how to store or create a table on my database using vb.net i'm having hard time to create a table on my existing dbase
here my code;
Dim ntable As OleDb.OleDbDataAdapter Dim mtable As New DataTable con.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:Documents and SettingsjessprDesktopmydbasesample.accdb"
[Code].....
when i view my access dbase i cant see the table that was created on my code. how can i view that table?
The following code creates a table in a mdb file.Dim tblName As String = Trim(Me.txbTblName.Text)
Dim Source = Trim(Me.txbLoadDB.Text) Dim Pass = Trim(Me.txbPassDB.Text) 'Define the connectors Dim oConn As OleDbConnection
[Code]...
I would like the table name be variable based on the textbox text but the following change creates a syntax error. Why is that?oQuery = "CREATE TABLE '" & tblName & "' ( ID Counter,Name TEXT(50) NOT NULL,PRIMARY KEY(ID) )"
I am working on a CMS system for my business, and need to be able to generate notifications dynamically into a control panel. Please note, I am using .NET 2.0, coding with VB and my data is all held on a MySQL database.This is pretty simple for most aspects, but as the whole thing is dynamic some things are proving more difficult.I have a set of tags which are dynamically generated with a repeater as follows:
<asp:Repeater runat="server" ID="locationRepeater"> <ItemTemplate> <p id='locationNotification' title="<%# Container.DataItem %>" runat='server'> COUNT DATA NEEDS TO GO HERE </p>
[Code]...
The data is really, really, simple, all I need to be able to do is query a table on my MySQL database for COUNT of ID WHERE locationName = Container.DataItem during each loop of the repeater... but I don't know how to do this.I'm thinking maybe I have to do this first, create a table in memory somehow, but I am afraid I have no idea how to achieve this.
Has anyone got any examples of a similar thing, it's kind of binding to a repeater from two datasources... each task is very simple, but I don't know how to put it all together!
I am getting a System.Data.InvalidConstraintException" ForeignKeyConstraint CompanyPasswords requires the child key values(-1) to exist in the parent Table. When saving updates to the parent and child tables.My parent table consists of 3 columnsCompanyID (auto increment, pk)Company NameURLMy Child table consists of 4 columns PasswordID (auto increment, pk)CompanyID (fk)User NamePasswordHere is all the code on the form
I'll get straight to my problem - I'm currently coding in Visual Studio.I have a table (countries) with the columns ID | Name. The table is filled with around 28 records.I also have a form with 4 combo boxes (set up as 1,2,3 & 4) that I want the user to select. These combo boxes will display the names from the table countries. I then want to use the selected names in the combo boxes to Insert into their corresponding ID into another table. For example England would have the ID 1, USA the ID 2 etc.So, is it possible to have separate combo boxes that will give separate ID values but using the same table? At the moment I can't seem to find a solution.Eventually the form will have more than 4 combo boxes so I don't want to use separate bindingsources for each combo box.
i am using ASP.NET with VB.NET to connect to a MS Access database. how can i make the sql statement to insert a new record into the existing table and join tables?
Dim obj_DataTable As New System.Data.DataTable("Category") Dim obj_DataSet As New DataSet() 'Declaring the array of DataColum to hold the Primary Key Columns
Next I have some labels on another form, that due to the design can't be in seperate panels. They are (lblChipColor1 - 6) and (lblChipValue1 - 7). I am trying to populate the color ones from the Array above. I can obviously loop thru the array, but I can't find a decent way to loop thru just the lblChipColorx lables ignoring the lblChipValue1x labels. It would be easy if they were on seperate panels. I tried adding the labels names to an array of type string and of type label, but got nowhere with that. Is there another way to group them, or build const array of label names, that I can work with?
I am trying to connect to a SQL DB and loop through some tables. My tables are linked on the EMPLOYID field between UPR00100 and UPR00102. I want to write data as follows: Level1, EMPLOYID, EmpName (from UPR00100) Level4, EMPLOYID, Address1, Address2,etc.. (from UPR00102)
Here is my data access code. I don't know how to code the loop. I know how to do it in SQL using a cursor but not VB 2005 Option Explicit On Option Strict On Imports System.Data Imports system.Data.SqlClient Module Module1 [Code] .....
I'm looking for some simple code that lets me create a Microsoft Access table via code.Currently all I do in Access is write and retrieve data from specific tables but now I want to be able to create them at runtime. Here is an example of the code I use to load some data just so you can get a feel of what I'm currently doing. Hopefully there is an easy way using the same rough way that I'm currently dealing with databases.
Code: Public Sub LoadCareer() Public rs As New ADO
We have an access database that contains Version table. the same file is stored in 2 separate locations, how would i pull the information from both c:db1.mdb and \servernamedb1.mdb's table so i could compare the two?
I've got a form where a user enters data. When the user submits that data, it inserts a record to two separate tables via a dataset. One of the records has no problem being saved into the database (in the table it was put into), but the other record seems to temporarily be in there (according to a third form), because it exists for the duration of the application, but when I exit, and then check the database, it's not there, and it's not shown on the third form when I restart the application again either.
I have a 5 tables in my database and i want to access all my tables togather at a time.e.g.I have a code for one table i.e. rs.Open "select * from Group_info", con, adOpenDynamic, adLockBatchOptimistic. instead of Group_info table i want to access 5 tables also as Login_table,User_info table,group_name table etc. How i do that
I have two tables Employees and CafeLogs. Some employees can be cashiers and also customers at the Cafe shop.
Table structures:
Employees: EmployeeId(PK) , FirstName, LastName CafeLogs: LogId (PK), CashierId, EmployeeId, Value, => CashierId and EmployeeId are the data from column EmployeeId of Empoyee table
Table relationship:
Employees 1:N CafeLogs (CashierId (FK))
[code]....
Right now I know how to select only LogId, Employee's name, and , Value, not with Cashier name yet.
Dim query = From log In db.CafeLogs _ Join emp In db.Employees On emp.EmployeeId Equals log.EmployeeId _ Select log.LogId, emp.FirsName, emp.LastName, log.Value
I have built an Access 2007 database with some data stored in it. I have managed to export data using VB2008 from that database to Excel 2007 and have it automatically draw charts based on this data and a query in the Visual Basic Code. One of the results looks like this:
I have been using adodb as my database connection to mysql from vb.net, now I want to know if i can create a query string with 2 separate query like so: vb dim querystring as string querystring="update table1 set columname = 'value' where columnname='value';update table2 set columname1 = 'value1' where columnname2='value1'"
Then I can include that to my recorset: vb dim rs as adodb.recordset rs = new adodb.recordset rs.open(querystring,con, ADODB.CursorTypeEnum.adOpenDynamic, ADODB.LockTypeEnum.adLockOptimistic)
I don't know if this is doable, maybe with Linq, but I have a List(Of MyType):
Public Class MyType Property key As Char Property description As String End Class
And I want to create a Dictionary(Of Char, MyType) using the key field as the dictionary keys and the values in the List as the dictionary values, with something like:
New Dictionary(Of Char, MyType)(??)
Even if this is doable, internally it will loop through all the List items, I guess?
The remarked area works fine when I'm accessing a specific table. I've successfully inserted the products_model field into the combobox too. The datagridview does show the table names in the db using the SHOW TABLES sql statment, but I'm not understanding how to get this info into the combobox instead.
I am trying to move through a list "TodaysCard" and print the TimeOfDay.ToString into the first column of every row and to only create the amount of rows that are needed. But am a bit of a novice when it comes to this and can only get it to display the TimeOfDay.ToString value for the first item in the list over and over again. Just wondering how I can get it to iterate through each item properly.

I am currently updating an application I wrote to view Car Insurance Policies, using a backed SQL database and a front end vb.net GUI. I now need to make a change.
I haev added a new table which has all Active Policies, and i have the old table with every policy there has been active or not. We do an import from a separate company, and there is no Active/Not Active field.
I need a query/code that will populate an "Active/NotActive" field in the old table. For example:
When I create a form using only one table in a database this works fine. However when I create a form that uses at least two tables I am getting an error on my ReceiptsAdapter (or my SQLDataAdapter). It's saying that I am using the incorrect syntax and need the keyword "From." I am assuming that I am getting this error because I am using multiple tables in my SQLCommand statement.
Imports System.Data Imports System.Data.SqlClient Public Class Receipts
