Using SQL-Trigger In VB Project ?
Sep 14, 2009
I have created a Trigger in VS2009 in VB.net. I have used a SQL Server Project. Now I have successfully created this Trigger:
' Geben Sie fr das Ziel eine vorhandene Tabelle oder Ansicht ein, und heben Sie die Auskommentierung der Attributzeile auf.
<Microsoft.SqlServer.Server.SqlTrigger(Name:="myTrigger"
, Target:="users"

I have a main form that has a dynamically generated treeview and also a panel control. Depending on the selection made within the treeview the panel docks 1 of three diffrent usercontrols which are full sub forms(done for ease of modifing design of sub form rather than layering panels on top of panels).Upon button click withing usercontrol i wish to trigger event within main form.For example delete button wich then triggers to remove current selected node from treeview. code for 1 of three diffrent user controls
Dim ctrlQ As New QuoteUC(TrViewQuotation.SelectedNode)
PnlSubFormDock1.Controls.Add(ctrlQ)
Code for delete button for which i need to raise event.
If MsgBox("Are you sure you wish to delete this customer ?", vbYesNo, "Delete Record") = vbYes Then
Deletecustomer(n)
End If

i have to develop a software for motorola mc9090 that reads barcodes and rfids simultaneously, so i need to catch two different triggers: the one on the keyboard for barcodes and the other in the backside for rfids.the problem is that i didn't find any sample that illustrates how to set the trigger to read only barcodes, i found something on emdk 2.5 samples that shows how to set the trigger to read rfids but nothing for barcodes. So when i press any trigger the barcode reader is always enabled with rfids reader.Does exist a way to manage them with separated triggers?

For reasons that are beyond my control, I have three Projects. Projects A and B reference project C. Project A references project B so that it can open a large form in project B. I now need to open that large form from project C, but VB won't allow me to add a reference from C to B because that would create a circular dependency. I found a way around it, though. I created a Timer in A, and when I opened C from A, I passed in that timer. When the user performs a certain action, I enable the Timer from A, and this causes C to open B for me.

I have a project that I have created, it something like a contact database.It is complete with its own sql server database, and controls and forms.I kinda of understand that I can include this project into another project.This is the tricky part,Can I include my contact project into another project and add more items to the database and forms in a new project?What I'm after is like using classes.My contact database would be like the base class, and the new project would be adding more features to that project.

This is my very first trigger and I'm not sure I have it set up correctly. I have a table called PayTypes. Here is my trigger syntax:
[code]...
I run this with a breakpoint on the first line, update my VB.NET datagridview (which updates and saves just fine), but the breakpoint never gets hit. Am I going about the setup of the trigger incorrectly?

Maybe there is a better way to do this. The jist of I want is to have SQL Server raise me 2 types of errors: a WARNING and an ERROR from a trigger when I update a table. If SQL server returns a WARNING the trigger should COMMIT but show the warning to the user (using .NET - preferably through a SQL Exception which is only raised if severity > 10) and if it is an ERROR the trigger should ROLLBACK and show the ERROR to the user (through a SQL Exception).My attempts (needless to say this isn't working) at this was to have a trigger like this:
ALTER TRIGGER [dbo].[TR_TRANSACTION_UPDATE]
ON [dbo].[tTRANSACTION]
FOR UPDATE

I'm having difficulty understanding how to set up a simple trigger. I have two Tables, "Customer" and "Order" Both tables have a "CustomerID" field, where the one in "Order" points to the ID in "Customer". When a record from Customer is deleted, I want all records in "Order" deleted where the CustomerID is the same as the one being deleted from "Customer". Trigger for the Customer Table that would do this?

I have a CRM application that I would like to programatically post new records and updates to, based on values in other tables getting inserted or updated. Problem is because of how this CRM app was designed I cannot use straight SQL insert/update SQL commands. This is because the database has some proprietary account#/record ID generation algorithm, and also writes to a log table using some pretty cryptic looking values.
The only way to ensure the integrity of the data is to use a the COM based API they provide. How can I send calls to this API from SQL Server code, I'm guessing a CLR user defined function? Can anyone point me to such tutorial on the web?
The updates I am making MUST be in real time, that is why I need to use a trigger that calls this app's API.

I have this code in my ViewProductsInventory (which is called from my MainForm by ShowDialog):
Private Sub ViewProductsInventory_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.Tb_inventory_datesTableAdapter.Fill(Me.InventorySysDataSet.tb_inventory_dates)
Dim inventory_date As Date
inventory_date = Me.cboInventoryDate.Text
[Code] .....
Upon clicking the editbutton will execute EditForm.ShowDialog()
And in my EditForm the record will be updated, after which will trigger ViewProductsInventory.btnSearch_Click( ViewProductsInventory.btnSearch, EventArgs.Empty)
And then the error "Conversion from string "" to type 'Date' is not valid" occurs.
I tried Msgbox(Me.cboInventoryDate.Text) and returns nothing. I'm assuming that my cboInventoryDate is not being populated at this time therefore when btnSearch_Click is triggered it receives nothing.

Am displaying list of available documents in the data grid which are retrieved from the database. Once we click on a specific one then it will retrieve PDF document from the server and display it in the browser.Currently, if I click a document from the list in the datagrid then it will display the PDF file in a new browser. Here is the code for that :
ds.Tables(0).Rows(i).Item("DOC") = "<font color=blue onmouseover=""this.style.cursor='hand';"" title=""Click for PDF"" " + _
"onclick=""location.replace('index.aspx?Name=" & link & "')"">" & docNum & "</font>"

I have a set of accordian divs (powered by the prototype library) in an asp.net page. I would like to save the state of the accordian, so when a postback event occurs, the same div is open rather than reloading the page entirely and opening the default div.
My plan was to set a page control value with the ID of the open div using the div's toggler click event function, and then fire a click event after postback calling that same div (using the value of the control holding the div ID) as the target. I'm not sure how to fire a javascript click event from vb.net however, and this sure seems like a lame workaround.
1) can you tell me how to fire a javascript click event from the vb.net codebehind page
-or-
2) is there a more elgant way to do this?
