Executing COM API Calls From SQL Trigger
Apr 2, 2012
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've created a page that makes several calls to different rss feeds based on the keywords I pass to the page. The problem is that each call takes .5 - 2 seconds to get a response and display the results. If I multiply the number of keywords by the time I end up with a very slow loading page. Is there a way to execute all of the calls at one time?

I am using VB.Net 2008 and ADO.Net to do a Batch Update to our Oracle database. The updates are working, but there is a trigger on the table before the row is updated to enforce a member's termination termination date. So if I was trying to set the termination date (via the batch update) to 31-Jan-2010 but the member had a claim that was processed on 2-Feb-2010 the trigger would force the termination date to be 2-Feb-2010. However, the trigger is NOT executing when the batch update runs?Is there any Oracle DB Admin option that would disable Triggers on Batch Update?

What the Win32 API is? I have looked around but no where really outlines what it is. Is it basically a set of procedures, outlined by Microsoft for programmers in order to get services from the operating system? In essence is it the equivalent to making system calls abd and library calls in UNIX? And yes I now Windows makes library calls too.

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 been using DBTransaction for my current projects that access a single database. However, I read some documentation on TransactionScope and was wondering in which scenario would using TransactionScope be better? Or should I be replacing DbTransaction calls with calls to TransactionScope?

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 some time ago I have notice that my App on every start make a call to csc.exe and starts it. I have google-it and found out that csc.exe is some kind off on-the-fly compiler for C# (If I understand it correctly ) but my App is in VB.net. VB.Net code to make my App on every start calls csc.exe?

I have created a Trigger in VS2009 in VB.net. I have used a SQL Server Project. Now I have successfully created this Trigger:

This should be fairly basic, but say I have a Public property as local variable on my WCF service, and I set this in one call to the service. Is there a way to preserve that data for another call to the service? (Without writing the data to xml or a db, and re-referencing it or anything like that)
Executing the calls from the Winform:
Public Class ClientSideWinForm
Private proxy As ServiceReference.Client
Private Sub Client_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

I have an application which has been succesfully installed on a number of different client machines.
The problem I now have is that I have been asked to allow third party applications, possibly written in a non .net language set to plug into my application and execute some of the code. Just a handfull of properties and half a dozen methods.
Now I can wrap up these properties/methods, make them public and have them in their own project which will be part of my solution but I have no idea where to go from here.
How do I make this portion of my application accessible to a third party application written in unmanaged code ?

I'm having some trouble finding the syntax for making function calls to unmanaged DLLs in VB.NET. Let's just assume there's a function "Connected" in unmanaged DLL "Connector.DLL". I want to call this function by creating an abstract function call to it.
I've seen some code out there that looks something like
[DllImport("Connector.DLL")]
Public Shared Function Connect(ByVal intPort)
But that syntax doesn't work for me.

Once I click Sign in, I want the application to test to see if the user has internet. If it does I want it to call another sub. If the network is not available I want a message to come up and say Error, no internet connection.
This is what I tried but can get it to work If My.Computer.Network.IsAvailable Then Call testnet()
else Messagebox.show("Error", "Truoble connecting to data base")

I have a VBNET app to scan my Active Directory using WMI calls and return some basic informaiton such as Dell Model name, current user logged on, Dell Service Tag etc my issue is the app becomes unresponsive whilst it scans and i have to wait for it to finish looping before i can work with it, in the past a do events used to suffice
I think Multithreading is the way i may need to go, whats the best approach? I tried to use Delegates but it doesnt seem to have made any difference
below is my for next loop code that calls the functions, the last section "Private Sub Button1_Click" down is the Delegate code i attempted

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?
