Isn't there a way in VB to pass an array literal? Say the subroutine ask for an array of integers and you have just one. Can't you do something like
DoSomething({MyNum})
instead of
Dim MyNums as Integer() = {MyNum}
DoSomeThing(MyNums)
I'm thinking I'm just missing some adornment to the array literal inorder pass it.
I have a GridView with Cell 0 containing the ID that I need to pass to a Public Sub.
I cannot figure out how to pick the value from Cell 0 in order to pass it to the Sub. I have tried experimenting (see the Dimmed EventID below) but have failed. Here is my code:
Protected Sub gvAppointmentsCalls_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles gvAppointmentsCalls.RowCommand
[Code]....
Is it considered bad practice (VB.NET or any language) to code a function with both ByVal and ByRef parameters as used in my getFile function below?
Function getFile(ByVal channel As Integer, _
ByRef Filename As String, _
ByRef Filesize As String) As Integer
End Function
Dim status As Integer
[Code]...

View 16 RepliesI am using sockets to send message between computers. I send the messages alright. What I want is when the message "x0x" comes, the client must be closed within 5 minutes. Teh admin can cancel the request by sending message "-xx" as well. The routine that checks for incoming connections and accepts messages uses WHILE TRUE...END WHILE since it must always listen. Once I get a message, I need to fire a timer control or other that fires within 5 minutes. But the program cant leave the WHILE TRUE at all. If i exit it early, the timer fires and the program does get exit. How do I fire the timer or other routine while still the WHILE TRUE routine checks for incomin connections and messages?
View 5 Repliesis there any way to reference a particular code routine in VB.net external to the current loop/routine?Example:
If Var01 < 5
[Routine A]
Else
[Routine B]
End If
where Routine A and Routine B are code sequences at the end of the entire program -- such as outside of the current sub or class? The idea would be to reference an otherwise repetitive code.
I have a sub routine where I pull in information from a database. I want to use variables from this sub routine in another sub routine. I tried making everything public but it doesn't want to be friendly and share.
Dim strEmail as String
Public Sub readDB()
strEmail = "whatever@doohikcy.com"
[Code]....
The readDB would read the database and set the variables and do whatever it needs to do. Then when they submit the form it would e-mail the form to whatever the email address was.
I am writing an OPC Client in VB.NET (2008) and I am using an OPC wrapper from Graybox. I am having some problems with the data types. I have an Array of String that contains all of the OPC Items that I wish to read from the OPC Server. When I attempt to use the Array of String, Option Strict causes the following compile error message:Error 5 Option Strict On disallows narrowing from type 'System.Array' to type '1-dimensional array of String' in copying the value of 'ByRef' parameter 'ItemIDs' back to the matching argument. How do I pass the Item ID's (all strings) in an array?

I'm writing a wrapper class to expose a subset of the functionality of a .NET FTP library edtftpne from Enterprise Distributed Technologies.
When you call the edtftp's GetFileInfos method you get an array of FTPFile objects returned. I'm able to iterate through these but I don't know how to pass them on as a new and different object array containing only Name and Size for each file. Here's the code I have. Sorry it's a little confusing because I have my own class named FTPFile and the .NET library I'm using also has a class named FTPFile. I'm using both of them here. I should probably change the name of my class just to avoid confusion:
Public Function GetFileList() As FTPFile() Implements IFTP.GetFileList
Dim ftpfiles() As EnterpriseDT.Net.Ftp.FTPFile
ftpfiles = fCon.GetFileInfos 'Fill object array
[Code]....
I'd just pass on the object array that I'm getting from the GetFileInfos method but COM clients won't have access to the class/object EnterpriseDT.Net.Ftp.FTPFile without me rewriting it, I'm assuming.
I have a .Net application (VB in particular, although I would this to be as language agnostic as possible) that uses a COM object (made in C++). I need to implement a event in COM that passes a char array from C++ to .Net. I guess I need to convert the array to a managed array; How can I do this?

I have a simple VB.Net Form that acts as an interface to a control library with a public API.
One of the API calls takes an Array of UIntegers ByRef:
Public Function Get_Values(source_id As Byte, first_value_address As Byte, number_of_values As Byte, ByRef valuesOut As UInteger()) As Integer
After the call, valuesOut will hold a list of values number_of_values long from source_id starting at first_value_address.
There is a hardware driven limitation that the max number of values returned is 15 regardless of requested length. I need to get 28 values into an array from my VB.Net code.
Is it possible to send only part of an array variable to the function similar to this C code?
uint[28] values;
Get_Values(0, 0, 15, values);//get first part
Get_Values(0, 15, 13, &values[15]); //get second part of data

View 4 RepliesI have several parameters consisting of separate System.Byte() arrays. What I need is the syntax for a function declaration where the parameter is an array of arrays - I do not want to delve into System.Collections, and it's my preference not to CType each array into an Object and then back into a Byte().
Problem I'm having here is that:
Public Function MyFunc(arrayparam() As System.Byte) As System.Byte()
accepts a single-dimensional Array of individual Bytes.
Then Public Function MyFunc(arrayparam() As System.Byte()) As System.Byte()
