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

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 am using VS2008 and SQLite. I have created a database and several tables and am attempting to populate the tables with data from arrays.
The following code (example) works fine but stops after it inserts 30 to 50 records. I am running the VB code in debug mode and when it stops, I press pause to see where it is. It stops on "SQLcommand.ExecuteNonQuery()" and when I press continue (F5) it will insert another 30 to 50 records.
I do not get an error message. Is this a timeout issue? How do I keep the loop running to the end of the array?
I have a database and I have a form that you can add questions to the database. Once the question has been added, I go to the quiz which uses the database and it goes through all the questions twice. I was wondering why this is happening [Code] Also I was wondering how do I set up the form to be the first form shown on the program?

how do I set up the form to be the first form shown on the program?
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.
I am looping through a database with pdf locations. The application is button click event driven. The problem I am having is that I display a pdf. If the user clicks on the button then the pdf information is inserted into a database and the loop should be taking me to the next pdf. However, this loop does not seem to give what I need. What ends up happening is the first pdf gets displayed twice. I think mainly because I display the first pdf onload, but when I click the button it agrees and grabs the first item from the database. And it ends up falling behind because its restarting the query and I cant quite figure out how to get the button to catch the first displayed pdf, or skip it entirely since I am using a welcome pdf. So on the welcome pdf that is supposed to be displayed initially the user clicks agree and it agrees to the welcome pdf instead of just skipping it. I am not quite sure how to just move past the pdf.
public sub onload() display the welcome pdf end sub
[CODE]...
Now if I run the code without the loop it works fine. I just end up having to run the app however many pdfs I have in my database.
query data display data insert data Windows.Forms.Application.Exit()
To display pdfs I imported the com control for adobe so pdfs get displayed like this:
I am trying to make a database, fill it with tables and then fill the tables. I am having problems connecting to the server and am really not sure why. I have posted this thread in two areas of this site because I was not sure what was the best area to put it in. [code]
Currently I have a problem with updating my database with values in my Data Grid View.
On my form I have a "Populate" button and "Submit Details" button.
The "Populate" button fills my Data Grid with numerous lines of data.
On the click event for "Submit Details" I want this data to be inserted into a table in my DataBase by looping through each record.
For Each dgi As DataGridView In DataGridView1.Rows
Dim productCode As String = DirectCast(dgi.FindControl("product"), Label).Text Dim description As String = DirectCast(dgi.FindControl("description"), Label).Text Dim quantity As String = DirectCast(dgi.FindControl("order_qty"), Label).Text
I am trying to create a form which will be fed by an underlying database to create multiple form fields for each entry in an underlying database table. This is for a program to monitor patients under anesthesia, and prior to surgery, the doctor will choose which monitors they will be using. Then, on the actual monitor screen which will pop up every X minutes, there will be a text box and a check box for each chosen monitor. I am relatively new to VB, so I have tried to illustrate what I am needing but using the logic that I know from my previous life in PHP.
I am using DevExpress's layout control to place the form fields, so that is the code in the middle of the first loop (on_load), and I know that part works, I just need to know how to name the fields and then recover those fields and commit the values to the database. (the text boxes are added to the database, the check boxes are used to determine if an entry is made for that monitor- i.e. at the end of surgery if a monitor is turned off). I know that my syntax for naming the fields is no where close to correct, and it probably would not work in PHP, but I remember doing something like this in a PHP application I built long ago. [Code]
I've got two different tables in my database. One is Class and other one is LAREACT and both of them have a key field of MAIN FACILITY USED. In the following part of my code a DataTable will be generated based on the sum of the records on both tables.Based on the bellow code ACTIVITYLOOKUP datatable is having "MAIN FACILITY USED","Description","TypeName","Type","Id" columns. The issue happens when there is a row with the same MAIN FACILITY USED entity. The datatable will not show it (filter it?). Do you know where the problem lies? and how it will be fixed without any modification in database?
I have a form with 3 datagridview controls that are bound to tables in a sql database. When the form loads for the first time the data is displayed correctly. If I add data to the db on another form then show the first form again the data displayed does not include the new data. If I close the app and then open it again then the new data is displayed.I cannot figure out how to manually refresh the gridview. I have tried calling the fill method of the adapter, using the refresh method of the gridview and parent control and form with still no luck. I have a ASP.net project I'm working on also and it is so easy to refresh the sqldatacontrol and the gridview and I would have though a win form would have been just as easy if not easier.
I have a database (acces) with 3 tables Table one has Id nr 1000 table 2 1000000 table 3 Id nr 1000000000 First table makes Id nr from 1001 to 1999. On Id nr 1001 i have multiple ID nr on the seccond table 10010000 to 10019999 and on the second table ID nr 10010001 i have multiple ID nr on the third table. This will last a while but the tables will fill up. Now i work with the Max value to find the highest ID number and add one to it.
how to create a local database, create some tables and set relations between those tables (just like in access) and I can show, add, edit and delete that data from a form.
but what I have yet to figure out is if I have 2 tables (i.e: tbleName, tblFood) and I want to have multiple tblFood items show for every 1 tblName item.
I've found that if I add a txtbox of the name table and a datagrid of the food table, the datagrid view shows all the food records, not just the ones for the name txtbox.
My first method is trying to get all entries in one of the database tables. However when I try to build the solution this is the error I get:

hello everyone, i m using treeview control in vb .net . How do we usee a recursive function to add data at different levels from different tables in a database.
I was wondering if there is any way to bind TWO different database tables to ONE textbox in VB? I've spent the whole day going through tutorials and different webpages and I've found nothing at all on this...
Well let me try to explain what I want to do exactly: basically I have multiple buttons on 'Form 1' and a textbox on 'Form 2' asking the user to insert a value which will then go to an Access database. But here is where it gets tricky for me: IF the user presses Button 1, the Value inserted on Form 2 will go to a field in the database whereas if the user presses Button 2 to open Form 2, then the value will go to somewhere else and so on.
This would be easy to do if I was to create multiple forms or multiple textboxes, 1 for each button but what I really need is 1 form/1 textbox that would work for all of them... [URL]
I am using visual studio 2010 with vb environment, I am connecting to a microsoft access database with 2 tables, one table per form, i can add a record and save it no problem, but when I update a existing record i receive the error, this happens on both tables, i am using the standard navigation buttons on the forms.
This is my coding in vb.net. I have used two database (1) party (2)partydup. Structure of the tables: party table: fields :code, name1,add1,add2 etc. partyduptable: fields: code, description
In both tables i have common field ("code"). I tried to retrieve the value of "description" field from partydup table when the "code" field in both the tables are same. I run the below coding but it is showing the error as "No data exists for the row/column". But i have a record which contains the code field value as 123 in both the tables. Still it is showing the error.
I was just wondering if I can retrieve two tables from my database to one form? because i'm trying it but it doesn't seem to be working. just the first table i'm trying to retrieve is working.

Is it possible to insert/put a Timer inside the Database?Let say in my Database/Tables i have MemID, Name, Membership Date and Status (Active/Expired).for example MemID [ 1 ] Name [ Juan Paolo ] Membership Date [11-17-10] Status [ Timer ]in Status is it possible to save the time even while the program is close?..or code like if MemID 1 reach 2 Days all of the information of MemID 1 will be clear and Status will become [ EXPIRED ] , while timer is running the Status is Active, and if the Timer Reach 2 Days the Status will become [ EXPIRED ]
I have a problem using my database in which I have a table with product names, codes, prices and information. I use the below method to get connected to my database and tables.

I know this is a very basic question but it has been awhile since I created a project with a database( been using a lot of XML). I created a database then selected it as a data source added some controls to some forms. Then I realized I needed to adjust some tables and I needed to add a whole new table. I deleted the controls and updated the tables that needed some adjustment. Now I would like another table. Can I disassociate the data source and do my adjustment to the database?
Have I created a problem with the binding object since I just deleted the controls on the form. I have written classes and some logic or else I might just start over. I guess I could copy those files but I am wondering if there is an easy way to fix what I have started. I realize that there are alot of questions here so any resource on how to modify a database that is attached to a VB.Net project.
