I'm trying to add information to a SQL database. I've had trouble getting it to update (and I'm only doing one entry at a time!). However, even one at a time gives me trouble. The red line of code gives me this error: Update requires a valid InsertCommand when passed DataRow collection with new rows. what I'm doing wrong--I think it may be syntax, but I'm think the parameters are correct.

Okay, I've made a local database now and everything is okay. But I don't want the normal data grid view, I want to display the information in a list view. How can I do that? Do I have to make some sql queries or something?

User need to select their prefferable data to show in report. What i did is i have a clear command first to delete the temporary table. The temporary table is basically a table to stored user selection parameter data. After the clear command, i have
a insert command to insert user selection data into the temporary table. What happened now is when i run the program exe, first run of the report is work fined, but not the second and the following times of execution. It will return null or blank report. The weird thing is when i execute it from development environment, it seem like the report is able to pick up user selection parameter and run the report for the first times and the subsequent execution.

Not inserting in the database but showing in application. how?
The program is currently trying to pull information from three different database tables and compiling the information onto one screen, to do this i am using three different connections and a function to handle the data at each stage. The issue is as my code hits PageLoadStage of "2" and runs the QueryDatabase() Function i am encountering an error of: "OleDB exception unhandled: No value given for one or more of the required parameters." This occurs on line 15 of the first code snippet. Can anyone explain this and/or identify any code issues if that is the cause.

A form I created, was able to modify and shows when the program is run has suddenly changed in the solution explorer. Now when the form "MainMenu.vb" is highlighted in the solution explorer the icon for "view designer" vanishes from the toolbar. The "view code" shows "MainMenu.vb" but there is not any code there and only an empty "General" and "Declarations" show. The icon to the left of the "MainMenu.vb" is like a module icon not a form icon.

This is for visual basic 2008 express edition.Ive been trying to update records from the table of my memrec.dbml and dbase1DataSet.xsd in the visual basic environment.Im not using any sql database server but Im just using the built-in sql server within the visual basic 2008 express.I was able to add records and retreived it to display in the textboxes.My 1st block of codes I used to edit records has an error message which says:NotSupportedException was unhandled - Sql server does not handle comparison of NText, Text, Xml, or Image data types.
My 2nd block of codes I tried to used doesn't have any error and it ables to change the records while at runtime but when you exit the program the changes was not save at all cause when you run it again the records that were changed during runtime goes back to its original records.Let me take you a look at the two blocks of codes
[Code]...
Questions:
1.What do you see as possible cause for having an error in 1st block of codes?What's the remedy for that?
2.For the 2nd block of codes,what is the valid update command to be added in the line in order to save the changes not just during runtime but until you exit the program and run it again?
I'm going through a book which is teaching me some basic coding principles of the language. The current section is detailing how to set up a master child form using two tables linked with a foreign key. The master table is displayed as a number of text boxes, and below is a grid with the child table which shows related records to whatever master record you happen to be checking out. At the top of the screen are the default navigation controls that are added with the grid. The master table is named Person and the child table Book. They are linked using a foreign key and have cascade set up on them.
The book informed me of the code required under the save icon on the navigation control so that when it is clicked both tables will be updated as required. It is as follows:
If Validate() Then
'Make sure editing has completed on both master and child tables
Me.BookBindingSource.EndEdit()
Me.PersonBindingSource.EndEdit()
[Code] .....
I have double checked that the code matches that shown, so this should in theory work fine. But if I manually delete a record from the Book (child table) grid and then click the Save icon on the navigation bar it comes up with the error "Update Requires A Valid DeleteCommand when passed DataRow collection with deleted rows".
Why changes made are not permanently saved to the database? I gather that it's using a "copy" of the data in the database but how do I get the code/form to make changes to the actual underlying database records as well as just the copy? I find this system very unusual, if someone deletes a record in the application why would anyone want this to be just done temporarily?
I am creating a form that creates new users and then updates them to a dataset, I have done this ok, but I am getting a runtime error when I delete a record. Please see below the exception being thrown
"Update requires a valid DeleteCommand when passed DataRow collection with deleted rows"
My code below
CODE:
So I know I need to add a delete command, but how do I write this in code and do I write it in the saveitem click event? I guess I would because the app crashes when I click save to update the dataset.
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
