I have queries using microsft access 2007 and vb.net. If I tried to execute it in microsoft access manually then the result was fine. But using code in vb.net I the result I've got was all the same
I've been programming a game recently and didn't want to make 99 weapons manually. I've tried making a loop do this for me. I've got the loop working, everything is perfect. But when I run the program and list all the Weapon(x).Name [x being any value between 0 & 99] they are all identical... HOWEVER. If I single step through the code it lists all the names from 0 to 99 perfectly fine. Why is it that single stepping through it produces what I want?
Private Sub CreateWeaponList() Dim StatName(4) As String 'Creating 4 pre-made names for weapons Dim WeaponName(4), RandomWeaponName As String 'Creating 4 more pre-made names for weapons For x = 0 To 32 Weapons(x).Type = "Sword" [Code] .....
How do I run Access queries from within VB? The queries have been written and saved in Access using SQL, and use a search-parameter (Team name) to return a single integer value (games won, points scored etc).
I have a access database setup which i am connecting to via ODBC, the access files already has all the required queries built and i would simple like to call them from within my application.I am using Visual Basic .NET and this is what i have tried so far..
I have an Access database with some table and some queries.Here you see one query which returns 2507 records:I also added this database to a vb.net project.However, if i try to fill the datatable of the query with the specific tableadapter, the datatable stays empty. Also when I click the query in the dataset and choose 'preview data' I get none of the 2507 records:Any idea why he won't load the records into the dataset?
I would like to be able to run a query that could tell me where a given table/query is used within all of my queries. I would like to do this with SQL but VBA is also fine.
Is there anyway to import a crosstab query from Access 2007 to VB 2005?If not, can I create a crosstab query within VB 2005 from the raw database tables
I use an access database and some queries return calculated fields resulting from functions in the code module of the database These queries are not listed in the "Views" tab of the query designer when adding a tableadapter in the data source designer
I am writing a message system on my server, the xml is something like this

I have developed a small ms-access based software with vb.net.
I've added auto-update capabilities to the software (mostly by using clickonce) to simplify the release of new features.
Every version of the software executes the update routine which may update also the existing database.Lately i've made few changes on the database structure adding few stored queries, so i want the autoupdate code to programmatically add these new queries to the existing database and make it perfectly up to date.
I haven't already found a solution to add stored queries to an ms-access database using odbc...I also tried to use the "CREATE PROC" sql statement but it does not seem to work with access databases, even if i create the query form the Microsoft Office Access front-end.I've found some examples that uses ADODB, but i'm using odbc to remain both x86 and x64 compliant.
In my .NET application I have to manage bookings for rooms. I enter the room booking via an SQL query to a MS Access database using an INSERT INTO statement.
Before I insert the booking, I need to check if a booking already exists for that time period, and if it does stop the user from being able to book at that time.
I have written code to retrieve a database result on the day and time of the booking they want to book, and the fact that Access would return data would mean that the user is trying to book over someone else.
how I can check if I have a resuklt returned. My code:
cn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=D:Databasedatabase.mdb;") cn.Open()
[Code].....
But this doesn't work, it displays the messagebox regardless of if there is a row returned or not. How can I check if a row was returned?
i just want to make a program with first form to enter the serial if correct just continue to form2 if incorrect just a popup say like "Serial Incorrect" how i can make it ?
I have an access database that has nested queries. For example, the querydef below is called qs_Pedon_type: SELECT qs_Pedon_basic.peiid, metadata_domain_detail.domain_id, metadata_domain_detail.choice, qs_Pedon_basic.siteiidref FROM qs_Pedon_basic LEFT JOIN metadata_domain_detail ON qs_Pedon_basic.pedontype = metadata_domain_detail.choice_id
My IDE is MS Visual Studio 2008.I just want to ask how can I get the result of a store procedure from MS Access using VB.Net and use the result in a Crystal Report.
I have a Windows Application Project that requires this function.
I am working on a custom report in access and I do have a query which I want the outcome to appear in a text box control. Howver when I link this under the control source property, It returns an error.
I am currently having a headache on how to solve this problem that i am facing. here is the situation: I have a combobox and a list box on the main form. The combobox will get the data from the ms access database. In the database, i have the details of a person's IC, Name and DOB say for eg on one entry I have D215311523C,SHAWN,13/04/1987 So now, my combobox on form load will show the list of dates in the database to allow the user to search base on the date itself by clicking on the selected date. So when the user clicks on the particular date say 13/04/1987, people in the database whose birthday is 13/04/1987 will be shown on the listbox.Meaning to say if i have 3 entries whose dates are the same 13/04/1987, 3 entries will appear. If there is only two entry, then two results will be shown. But now, when i do a single click on the date, one result will be shown. That is correct. But the problem is when i click on the same date again, three of the same results will be shown on the list box. that is it will display : 13/04/1987 13/04/1987 13/04/1987 which is not the case. Then it will show more duplicates of the same results if i click more times on the same date which should not be the case.
