What I have is a database in a Windows Form (via tableAdapters etc., basically the default stuff VS adds). What I need to do, is add a very simple record of a name and score (the "place" is an auto-number). I have not even been able to tackle sorting the table, because I can not even figure out how to insert...
ok I have a weird issue. I created a master record in the master table and then a record in the detail table. when creating the detail record i get a Specified cast is not valid error. Now another weird thing is that once I create the master record I can't query and verify it was created. But when i got to sql management studio I can see the master record. Below is my two procedures and the table definitions. Master table primary key is INVNUM child table primary key it INVLIN_ID and the reference key is INVNUM
I have been utilizing Scott Gu's tutorials on LINQ to SQL to try to learn some LINQ. I have been able to view, retrieve, and update records but I am unable to write new records into the database (MSSQL). Scott starts getting into inserting rows in the fourth section of the set of tutorials. As you can see on that page (or may already know), in order to add a record you must do the following (VB.NET)[code]...
I have one problem regarding how to check whether the record already have or not then do insert or update.I'm using firebird database.i want to pull all record from one table to other database . Here my coding but i'm get stuck to do insert or update. [code]
I have this form that acts as a patient history form, so when I click the "New record" button I want the form to be ready for new input and for it to save the data when I'm done. I also need a button to delete records, but I am completely terrible with databases so I have no idea what I need to do to add records. I assume I can just have the form clear to be ready for the input but I don't know how to get it to save the data.
The whole thing works in Access but I guess that's older VB or something, they were using the acRecord to be able to cycle through all the records of the database. What is VB.net's equivalent?
I am learning MS Access by reading books and i have no formal education on computers. I am trying to insert one record from a form (not bound to any table) by using VBA - Class Module. When following codes are run, the dialogue for parameter value of A and B are opened instead of using the value of variable A and B which is the value of txtbox1 and txtbox2 respectively .
Dim MySql as string Dim A as string Dim B As String A = me.txtbox1.value B = me.txtbox2.value MySql = "INSERT INTO tblcom (fieldA,fieldtB) VALUE (A,B)"
I made a window for the purpose of managing "profile" records
while the navigation and updating is working
i cannot seem to get insertion working, as well[code]...
when i press add, i get a new empty record, when i fill it in, i see that the collection sees it, as there is an onform listbox showing the profiles, and it gets listed there, so its actually attached to the list, but the savechanges command does not insert it into the db
there may be some validation errors upon insert, but then i would get some indication, right? now its just silently failing. as if i never tied to commit changes

I have a problem with this code.It loops all records in tables SAP_CC and ORCL_CC and matches all records where amounts are equal in both tables. The problem arises when I need to update the tables.I need to update a column on tables SAP_CC and ORCL_CC, setting the records as matched and also to create new records on the CC_RECONCILED table.
In the If ¦ End If the line .Open("CC_RECONCILED") throws the COM Exception:Operation is not allowed when the object is open. I cannot close rsl¦Is there a way of achieving my goal?

I have an asp.net page that has 4 fields, one of the fields is populated on page load as per the vb code below.
I'm trying to get the selected value (or text) of the dropdownlist control and use it as the value for the first field in the record however every time I select the second or third value in the dropdownlist and click the submit button the new record that is created is inserting the first value in the dropdownlist.[CODE...]
I am pretty confused about lambdas. What I am trying to do here is write a function that will return an object from a certain table with a certain criteria. So lets say I can write: function GetRecord(TableName as string,Criteria as string) as object 'do the linq-stuff end function
Now I don't care if the parameters are strings or lambdas or whatever, but the end result must be that at runtime I don't know which table and which criteria will be used. As sometimes I need to get a customer record by email and sometimes a product by id etc. If possible I would prefer returning a list of matching objects and then I would just use .firstordefault when I want 1 (such as by id...).
I am using the following line of LINQ to drill down into an element. Is it possible to expands this code to drill further down so that I can add content to the <population> element in "Test2". I want to be able to do somthing like element.SetValue(1000000). However I need to expand the code below so that I can pass the entire query results into the variable called "element"'
Dim eles = From c In doc.Descendants("File") _ Where c.Attribute("Name").Value = "Test2" _ Select c

Teh table only contains these 4 fields and another field which is an automatically generated number called nbrQuoteID .All of the fields are number fields but I have tried sending them as text to see if it made a difference (Threw up an error) but it didn't.

I am having a problem with adding a record to a customer table in a Microsoft Access database. I have worked for hours reading my textbook and troubleshooting to no avail. The copy and paste below from VS is a little messy. When I execute this code below the record is not added and I do not get an error of any type. When I go into debug mode, all of the parameters are correct and everything looks good. If I open up Access I can manually add the record but using my program nothing happens. All datatypes are string in VS and text in Access.
First an instance of the Customer Class is created and this seems to be successful. But when I take that customer object and run the AddCustomer method of the customer class it is not successful in that the database does not reflect that the record was ever added. [Code]
