Simulating IntelliSense's Parameter List For A Function Call (like MsgBox Button)
Jan 29, 2010I am creating a function and want to have IntelliSense pop down the list of valid options for a certain parameter in the same way that the MsgBox function behaves when you are typing your argument for which buttons you wish to include (such as MsgBoxStyle.OkCancel). I have done my best to search the internet but haven't found a thing which comes close to what I'm seeking. My monkeying around hasn't produced a satisfactory solution, yet, either.
A related additional thing, which I can live without but that would be nice to have, is the description of the current parameter, which appears below the function description as shown highlighted below MsgBox (Prompt As Object, [Buttons as Microsoft.Visual Basic.MsgBoxStyle = MsgBoxStyle .DefaultButton1], [Title as Object = Nothing]) AsMicrosoft.VisualBasic.MsgBoxResult
Buttons: Optional. Numeric expression that is the sum of values specifying the number and type of buttons to display, the icon style to user, the identity of the default button, and the modality of the message box. If you omit Buttons, the default is zero. This is my first post. I'm relatively new to VB .Net.

View 2 RepliesCall Function - Invalid Attempt To Read When No Data Present
Mar 25, 2009When I run my application the following code prompts an error. Ideally, I want to populate the TxtOracleNo with a value read from another table on my form based on certain conditions i.e., prac_no, prac_eid and pay_method is the same in both tables then populate the Oracle No on TxtOracleNo text box.
The error given is
"Invalid attempt to read when no data is present"
The function is shown below
Private Sub Oracleview()
'Open the database.
'Delete any existing record

Dim conn As SqlConnection = GetDbConnection()

I checked that data in the database and it is available in both tables. Probably, the problem is where I call the function. Presently, I call it on loadform.
Time To Call A Function To Change Data Being Returned From Database?
Jun 28, 2009I have two functions written in VB.NET:
1) The first function (call it GetValues()) returns values in a SQL database as a list via a stored proc. One of the fields is DateTimeSubmitted. All of this data is displayed on my webpage using a repeater control. It works fine.
2) The second function (call it NiceDate()) I created to change the DateTimeSubmitted to a nice date such as "one minute ago" or "yesterday".
My problem is I have no idea which is the best part of the process to do the conversion (at point of data extraction or in pageload etc.) or in fact how to do the conversion.
Call Storedprocecure With Parameter(0), Parameter(1) Etc?

What is the VB.Net that will do exactly the vbscript does? I like paramer(0) and 1 and 2 etc since I don't need to define the parameter(0) as integer or varchar etc. I remembered I have discuss this before and it is possible to do in VB.NET?
Function Syntax - Call A Function With 2 Arguments When The Function Is Only Defined For One
Apr 1, 2010I'm trying to undersatnd the syntax of calling a funciton and it seem confusing when I'm using a web service in ASP.net. Maybe this question should be in an ASP forum, but it is a VB question. This simple web service allows you to type in your name and it response with an alert box with you name.
My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for

View 2 RepliesCall A Function From Inside Another And Suspend It Until The Called Function Is Finished
Jan 25, 2010How can I call a function from inside another function and suspend the calling function until the called function is finished? I hope I can get some replies because I don't know how to ask the question and make sense:).
Anyway what I am trying to do in steps:
1. The user clicks button1 which triggers the click event.
2. From the click event I call a function
3. I then pop-up a form, that has instructions for the user to read.
4. After the user has read the form he will click the "Done" button and return to the calling function.
The problem is the the calling function continues to execute. I want to stop execution of the calling function until the users clicks the "Done" button on the instruction pop=up. I know I can use a msgbox but the instructions can be lengthly and does not look good in a msgbox.
I have tried the Call method with return in the "Done" button click but I can make that work. I also tried a goto statement but I can get that to work either. In the call statement I said call frmInstruction.show() and it got there but as I said the calling function continued to execute.

Threaded Function Call Slower Than Calling Function Directly?
Sep 14, 2010I have a function where I am performing a lot number of database operations inside a Sub. The operation when called directly like:ExecProcess()
takes about 11 seconds to run.However, if I create a Delegate, and call the sub using BeginInvoke(), the very same process takes over 40 seconds to execute.Here's the threaded code:
Protected del As ProcessDelegate
Protected Delegate Sub ProcessDelegate()
del = New ProcessDelegate(AddressOf SELocal.ExecJob)
Dim cb As New AsyncCallback(AddressOf Me.ExecJobComplete)
del.BeginInvoke(cb, del)
Anyone know what may cause a function to take longer inside a new thread, rather than calling directly?
