How To Trigger VB Function From OnClick()
May 31, 2012Am 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>"

Calling Function To Update Value On Trigger Of Event
Nov 8, 2010I think I have a timing issue. On the trigger of an event I call a function to update a value:
Private Sub t0_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles t0.Click
Input.ppProperty = "blank"
UpdateRecord("Hey", Input.ppProperty)
MsgBox(Input.ppProperty)
End Sub
[Code] .....
Notice the difference, the property does not update until the function is completely finished.
Why?

View 7 RepliesTrigger A Function In Form-application From A Service
Feb 27, 2012For a small project I need the possibility to "trigger" a function in a Window-form-application from a Service. So there are 2 program's. One is the visible Form application with textboxes and buttons and so on... The other is a sort of service program that runs on the Windows Service account.
Actually the second program is a command-line tool that gets fired by a PHP script from the Apache server. Because the command-line tool runs in another "environment" then the Windows-form-App, it is NOT possible to communicate (trigger) with both apps.
I know I have to use IPC (InterProcess Communication) and I have download the dozens of sample apps, but I still can't get it to work.
PLEASE can someone give me some sample code, or perhaps sample program(s) to help me out?
I think it's really easy to build what I want, but for me it's a no-go :-(
So for example it has to work like this:
PHP script (running at Apache server) runs a "console/service" app (already working) which "triggers" (via IPC) a already running Windows-Form-app (also already working app) that for example shows a MsgBox with the text in it that is sended by the "console/service" app.
VS 2010 : Trigger Event In Usercontrol To Trigger Sub In Main Form?
Feb 18, 2012I 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
Symbol Barcode Trigger & Rfid Trigger
Oct 6, 2011i 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?

How To Pass A Function To A Function Is Functors/function Objects Avaiable In VB2010
Oct 12, 2011I want to make an numerical integration method with takes in an analytic function and integrate it over a specific interval. For the numerical integration procedure I want to use some procedures in nr.com. The problem is that these are programmed in C++ and they uses functors to pass a function to the integration method. How can I do this in VB 2010?
I want to initialize the function (i.e. set a=1,b=0 for function y(x)=a*x+b) and then pass the function to the integration method. Then when the integration method call the function it only calls the function with one parameter (i.e. x since a,b is already set)
What is the best way to do this in VB2010?I want to make a general integration method where I can pass any single valued function and integration limits.
I have just started using VB, and from what I have found so far it seems like the tools you have is
- to us a delegate for the function
- to use a lambda expression for the function
- send a pointer/adressOf
- to create a function class/structure and submit this to the function
As for now I am most inclined to create a function-class. But I am not really sure how.F.ex. I make different classes for each "uniqe function" I want to integrate, but how can I pass them to the integration function when I need to specify the argument type in the integration-function-call?This seems like a basic problem which applies to many Math operations, so I think it would be very useful to clarify this.

View 8 RepliesC# - Commit And Raiserror In A Trigger?
Mar 17, 2011Maybe 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:

DB/Reporting :: How To Setup Trigger
Sep 14, 2008I'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?
View 1 RepliesExecuting COM API Calls From SQL Trigger
Apr 2, 2012I 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.

How To Trigger Event From Another Form
Feb 19, 2012I 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.

Asp.net - Trigger A Javascript Click Event?
Jan 27, 2010I 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?
