I have created a project that has an add a new record, edit record and a search form, that has multiple text, combo boxes and is working great.Last nite I have added a checkbox under my add new record form and i am saving the checkbox value to my database, so far so good. I would like to be able to search any record that is mark with a checkbox to show up in my search screen when I do a search: [code] The problem that i am having is that now that I have added the code to my project to search for the checkbox field in the search screen and if I leave everything blank and click on the the search button I get no record found. I expected to see all that data, since I have nothing selected. Now if I click my checkbox, as soon as I click on my search button I see that two records that I have added for my test.

View 1 RepliesI have a dataset; I want to create an equivalent record set. What I really want to do is create the XML that a record set can load; I have no other use for the record set per se. I want to be able to load recordsets on other machines (which use VB6 ins of vb.net) with this data. I found some code that loops through the columns in the dataset and creates the fields in the record set; that's executing. However, the code given to open the record set fails with "incompatible or incorrect parameters" or some such. [Code] I can see that a recordset is a construct meant to bridge between running code and a data store of some sort, but in this case the data is "stored" in the dataset, not anywhere else. I want to put that data in the XML form that the recordset uses, so that other code that can only use recordsets (ins of datasets) will be able to read it.

I just want to add a value from a textbox/variable and save it as a new record in a MS Access Database after a button click.
I've set up the database, set up the tables required.
From what I gather, I need to first link declare 'Imports System.Data' outside all the code. And also define a variable as a connection (Dim con As New OleDb.OleDbConnection) then access the database with "con.ConnectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source = PathName").
What else do I need to include?

What I would like the program to do is, you enter a value into a textbox and then press a button. The value in the textbox is searched and then the values in the database corresponding to that value are entered into the other text boxes. This is what I have so far:

I have a self referenced table it contains Employee information, an employee reports to another employee, I've done this by including a field named ReportsTo as a foreign key that would be filled with the primary key. My first question is when using a strongly typed dataset how would I insert the first record without raising an error. the only solution that I could come up with is to insert an employee with the name NoOne and reports to himself i.e the employee number is the same as ReportsTo, this solution would be hardcoded in my program and only works when there is no records in the table. This is ok as long as I don't delete every employee from the table and try to insert new employees, in this case my insert will fail because the NoOne employee number is "1" and this would violate the index. this case calls for reseting the index each time I delete all the employees.
View 2 RepliesI am working with some DBF database files and have an interesting dilemma. I need to search through a table, find duplicates and delete them. Problem... Table doesnt contain a key.
So Table looks like this:
Name, BadgeNum
I need to be able to find instances like this:
John, 10
John, 10
and then delete just one iteration of John, 10.
Is this even possible? A "DELETE FROM TABLE WHERE BadgeNum=10" will delete both.....

i have a situation where I need to search a table for a specific record that matches an ID number the user will specify. I know 2 methods to accomplish this. The first would involve writing some VB.net code that would call a TSQL statement and return the value through the return parameter. The second method would involve creating a dataset and populating it with a select statement.

I have been following a tutorial in a book Vb 2005 Jumpstart Ch 4..Anyway I have followed the books code exactly and the program runs.It connects to Amazons web service and allows the user to search and display books, the application also allows the user to save the titles that they wish by clicking an Add Title button, when the user does this the current focus title is saved to the database and can be viewed off line.When I hit the add title the record gets saved as I can hit the catalog button which opens a new form with a datagrid that has all the titles I just saved in it!! But when I close the app and run it again the catalog is gone?? back to no records again?Now ive never worked with SQL databases before and this is me just having a go at .Net so I have no idea whats wrong or where to look.[code]

I am trying to use RAP (rabid application development). So I have created a database with a datagridview to show all information and textboxes to modify the informations. So far so good.
The problem is created when I try to use the search facility on the datagridview. The search is working but the problem is that the textboxes are not following the search criteria . I can configure this manual but I would like to know which is the easier way to configure the textboxes to show the value of my search criteria.
I also want to know how when I finished with the search criteria and empty the search the text boxes to make the connections back as they were before.
I need to do a lookup in a DatagridView column. I would like something with the blazing speed of what recordset.seek used to provide. I am assuming that a similar function/method is available for use with the DVG. What else is there to use that is better than my present implementation.

For a school programming project we are supposed to create a database with 2 tables country, and continent.then we populate country with every country name, population and continentID. For continent we populate with each continent name.
i have completed this step, and i am able to run a linq query to display all countries and corresponding continent into a datagridview. My problem arises because we are supposed to display each record one at a time, and be able to cycle through one at a time. I cannot for the life of me figure out how to do this.
for example if i made a query to select all countries in africa, i want to beable to display the name of the country, and population in textboxes. then have a next button that will go to the next record.
