How To Pass Array Between Two Subroutines

Feb 4, 2011

I have 2 arrays X(n) and Y(n) where n can vary programmatically, no set value. I want to pass these two arrays between two subroutines.

Sub sub1()
...
call sub2(X,Y,n)
end sub
sub sub2(x,y,n)
...
end sub

I want to know how to prepare the arrays for the "call sub2" and how to extract the arrays in "sub2".

VS 2010 Sending Array Between Subroutines?

Dec 10, 2010

I'm having trouble with passing an array between subroutines

I have an array called "lines" which is loaded from a text file and then edited according to a series of checkboxes within one subroutine. Each line in the array is essentially a line from the text file

I then need this array passed to another routine so that it saves to a new text file once the save button is pressed. (in this case just the top 5 lines)

At the end of the section that creates the array i have placed this

From File Edit
Call Savefile(Lines)

The section of code below is from the section once the button is pressed

Save Code
Sub Save_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Savebutton.Click

[Code].....

Pass An Array Of String When A System.Array Is Expected?

Feb 24, 2009

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?

Pass Out An Object Array In .NET?

Mar 25, 2011

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 multidimensional array (not jagged array) that saves data from rows and columns of an excel spreadsheet. After it completes recording the data from Excel, I need to pass the array to another function.I understand how to pass a jagged array, but not a true multidimensional array.

Can someone point me in the right direction? I've done some searching on this site, and others, but most of the info only includes single dimension arrays or jagged arrays.

Pass An Array Literal To A Sub Routine?

Apr 2, 2009

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.

Pass Subset Of An Array To Function?

Jun 25, 2010

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

Pass An Array Of Arrays As A Function Argument?

Nov 11, 2010

I 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()

Pass Integer Array To C++ Active Control?

Mar 12, 2009

I'm using VB.NET within Visual Studio 2008.I have a ActiveX control on my form that contains a method that takes an Array. In VB6 I just passed in the array and it was populated OK. When I do the same in VB.NET, I get a result but the value of each index appears to be a pointer.Here is the C++ method code...

void CMyCtrl::GetRowInfo(const VARIANT FAR& vArray, short sNumRows)
{
// Declaretemp array to put the row list into
short asRowList[24];

[code]....

Here is the VB code (same VB6 and VB.NET...

Dim maintRowList(0 To 23) As Integer
AxMyCtrl.GetRowInfo(maintRowList, 24)

In VB6, the value of maintRowList(0) is in the range 0 to Windows screen height(its a pixel value)In VB.NET the value of maintRowList(0) is a value that looks like a pointer to me (e.g 285671429).In VB.NET, the type of the 1st parameter is Object. In VB6 it is a Variant. I've tried AxMyCtrl.GetRowInfo(maintRowList(0), 24) and got the same result. I think I need to get a pointer to either the array or the first element of the array but I can't see a way to do that. how I can pass an array to this type of C++ ActiveX method?BTW - I cannot change the ActiveX code so the solution must be within VB.NET.

Pass String Array To Unmanaged Code In A Dll?

First of all; I'm completely new to VB.

Pass a string array from Visual Basic Express 2008 to unmanaged code in a Dll.The array is Dimmed as in DIM myArray(11) as String

I'm developing the dll myself using Powerbasic.

The dll expect a 4 bytes pointer to a safearray's handle. As far as I have understood it; the array's string elements must be passed in ANSI format. The code in the dll will then use OLE Api to get the LBound and Ubound of the array and the address of the first element in array.
