When ever I try to update a record from data grid using a dataAdapter record it always showing ' update requires a valid insert command when passed data row collection with new rows' From specific sql server Table only. Resulting me holding up a project.

View 6 RepliesI'm still pretty new at .Net and database coding, and am working on a small program that is generating an error and I'm not sure how to resolve it.[code]The following statement is giving me the error below: m_DA.Update(m_DataTable)"Update requires a valid InsertCommand when passed DataRow collection with new Rows".I know the answer is going to be very simple, but I'm at a loss. I would greatly appreciate it if someone could point out the flaw in my code and how to correct it. And yes, I have done fairly extensive searching on this error, but none of them give any idea how to fix it, they just hint around at what's wrong.
View 9 RepliesThis was working on the last test, now it's throwing an InvalidOperationException saying Update requires a valid InsertCommand when passed DataRow collection with new rows. No change in this

What *has* changed is that I'm trying to fix the same error that's occurring on a different dataset in a different form. This should add a blank record to the dataset, then update the database. The blank fields allow nulls. The reason for this (and there may be another way to do this-I'm helping a novice fix up his code and, since this has been working, I haven't yet really looked at it) is to obtain the correct value for an identity field. We've found that when the row is added to the dataset, if it doesn't currently contain any rows, the identity value is set to zero-but when the database is updated, it gets a different value (because previously inserted rows have been deleted). So we update the database then retrieve the correct identity value before continuing.As I said, this was working fine-until I started working on the same problem occurring in a different dataset. So why would that affect this dataset?
I created VB.Net Win Form application in Visual Studio 2008 SP1 that connected to Microsoft SQL Server 2008.The DataGridView was used to connect the SQL Server 2008 and WinForms.When I delete or add records, run into error: Update requires a valid DeleteCommand when passed DataRow collection with deleted rows.
View 3 RepliesI have looked at multiple posts regarding this issue, but can't seem to find a solution. To keep it simple I have an Access database with a single table. It does have a field as a primary key. When I click the save icon on the Binding Navigator I get this error having to do with the following code:
Me.Validate()
Me.TitlesBindingSource.EndEdit()
Me.TitlesTableAdapter.Update(Me.VFCurvesDataSet.Titles)
I cannot set the Refresh the Data Table check box in Advanced Options of the TableAdapter Configuration Wizard as it is grayed out. Once again, I have a primary key.
The posts I have reviewed indicate that an UpdateCommand needs to be created, but I can't understand how it should be done. W

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?

Me.sqlDA_FrmOTUnit_Delete_Select_Venue_Period_UnitName.Update(SqlDS_FrmOTUnit_Delete_Select_Venue_Period_UnitName1, "OA_FrmOTUnit_Delete_Select_Venue_Period_UnitName")
the row gets delete in the dataset when i put RemoveAt(0). But when i want to refelect in the database, it gives me the error: "Update requires a valid DeleteCommand when passed DataRow collection with deleted rows."
Primary Key Issue!!!! Hell such a litttle mistake mannn... toooook so much time and so irritating...
I have a program that calls on an Access Database to get it's data. I wrote a public sub to speed up the data access commands when I needed them instead of typing everything out. When I use the DA.Update(DS,"tblmain") command it works fine EVERYWHERE ELSE but for some reason it keeps locking up in one spot and gives me this (non-verbatim) error:"update requires a valied insertcommand"Here's my Public Sub that accesses the database.

Update requires valid UpdateCommand passed DataRow collection modified rows. When I run the following code. But the strange thing is that I have similar code on another form and it works great. The only difference is the database table is different. I verified both tables and they look identical, as far as settings. I have verified that _Non_MS_Office_Licenses has a primary key that is unique. Looking in dataset manager I see the query for fillBy() is fine and it has all the insert and update stuff. At the end when it verifies it says all is verified when I configure the dataset
Dim row = FrmApp.Non_MS_Office_LicensesBindingSource.Current
row("Primary User") = Replace(CStr(TxtUserid.Text), "'", "`")
row("Staff Last Name") = Replace(CStr(TxtLastName.Text), "'", "`")
row("Staff First Name") = Replace(CStr(TxtFirstName.Text), "'", "`")

I'm trying to get a database to add a new row on this form. The user types a word into a text box, clicks save, and it should update the database. The table is called "text" for now, it's an Access DB, and it has two rows: ID, and userText. [Code]
I get the error at the da.Update line when I click Save. The full error is "Update requires a valid InsertCommand when passed DataRow collection with new rows." I'm not sure if I have to add an INSERT command somehow or if something in the code needs changing. If I add this line to the Save routine, I get an "Syntax error in INSERT INTO command": Dim cb As New OleDb.OleDbCommandBuilder(da)
I don't know if I should leave that out or keep it in since both give me errors.
I have a ClickOnce application deployed to many workstations in my office. On it's first run it adds a registry key to the HKCU run group that adds itself with a "-minimize" argument. On each login the program starts and seeing the command line argument minimizes itself. However when a update is published the program does not update. If the program is run from its menu shortcut without arguments it runs fine. I then looked up how to update programmaticaly and put that code into my program to run at startup.
But my.application.isnetworkdeployed returns False when command line arguments are passed to the app and TRUE when run without command line arguments even though in both cases it is network deployed. Since my program starts up with command line arguments and stays minimized while the computer is on there is no reason for a user to close the program and reopen it through a menu item but as of right now that's the only way the program updates. Is this a bug or how ClickOnce is supposed to work?
Example: Create a new program. On the form add a textbox. In the Form load event put something like:
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
TextBox1.Text = My.Application.Info.DirectoryPath.ToString & "" & My.Application.Info.AssemblyName & ".exe"
MsgBox("Is my app network deployed?: " & My.Application.IsNetworkDeployed)
End Sub
Deploy the app. Start it with a menu item and it returns True. Start it with any command like argument (use the path from the box) and it returns false. Why? How is that possible? The app didn't magically become non network deployed because it was passed a command line argument.

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?
Can anyone tell me why "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound." I keep getting an error "Invalid Operation Exception was Unhandled" error. All I am attempting to do is allow the user to select products from a list(or a second datagridview) and have it added to the datagridview so they do not have to type in every cell since the other cells are not visible because they do not purtain to their needs. Plus they will be able to save all items at the same time.

I have two datagridview's both are databound. First one shows items for sale and the second stores all the items that were sold. I am trying too transfer selected rows from one to the other but no matter what I keep getting told "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound."

I am using this code to Add rows to a SQL database, and it adds the row to the SQL database if column 7 is not null. After it adds the row to the SQL database, it deletes it from the Access Dataset, and updates the Access Database. Sometimes double rows seem to get inserted into the database, so I'm thinking there is an error in my logic somewhere here.
Dim rowcount As Integer = AccessDataSet.AccessTbl.Rows.Count
Dim y As Integer = 0
For x = 0 To rowcount - 1
txtRow = AccessDataSet.AccessTbl(y)
If IsDBNull(txtRow(7)) = False Then

I'm trying to insert a couple of fields into a csv config file and then update all other rows in the file at the same index by copying the previous 2 entries. I'm reading through each row and converting the row into a list(of String) because it seems to be the most flexible way. Ine initial insert works fine, but the code below doesn't. The actual insert code is:

pcIndex is the list index value from elsewhere in the code at the insertion of the 1st of a pair of values into one row. I need to update that index point and pcIndex +1 in all other rows. However it's not doing anything. Tried using lstSteps.Insert, InsertRange, etc. Am I using this right? Is there a better way? It seems to be over-writing the entry rather than inserting a new column and moving the others up, so it appears the list capacity value isn't updating - so I'm left with the initial row with 4 more entries than the others sticking out of the file.
