Hi, trying to send a defined type on the serial port, to do that I need to access the bytes for each value in that type.
Lets say I want to send a variable of this type as binary/byte data:
Type test
v1 As Single
v2 As Single
v3 As Long
v4(4) As Single
End Type
How do I get the individual bytes to send, in total 28 bytes in the example abow? Is there a whay to convert this type and others to byte arrays?
And then when recieveing, lets say a single float in binary as 4 bytes on the serial port, how can I transforme that 4 byte array to a single value in visual basic?
regards Me

Is there any built in function in "VB Script" or user code to extract substring from a line where each substring is separated by a delimeter like coma (",").
eg: str="subOne,subTwo,subThree"
im looking for a function like this XXX(str,2) should return "subTwo".
Please note i wanted to do this in VB Script
And also I dont want to use Split() function since i wanna this in visual test 4.0 and Split() is not available there.
Thanks in advance.

No, there is no function like you describe. If you can't use Split (the common solution to what you want), then you'll have to write the function yourself and either return all of the substrings in an array of strings or return just the one you want. It's up to you how you write it...

you need to find your first delimiter's index
make a new substring using the aboves delimeter's index + 1,
search the new string for your next delimiter
then repeat as much as needed

Hey,
I found a component here[^] for using FTP in VB.NET.
I have written a recursive loop to look through a directory and upload the files.
My problem is that you need to change to a directory (Using folder name on FTP only not having a full path) on one pass, then change to a sub folder on the next pass and so on, this ends up uploading this original folder structure:
Parent
------ Folder 1
----------- Sub Folder 1
------ Folder 2
----------- Sub Folder 2
into
Parent
------ Folder 1
---------- Sub Folder 1
---------------- Folder 2
--------------------- Sub Folder 2
So after ending one branch its doesnt go back to the root and start the other branch, As because Sub Folder 1 has no childnodes it should go back to the root and create the recursion of the Folder 2 branch, but it just recurses all the way through in one branch.
Is there a way to upload a single folder only, in this case the Parent folder, or a way to solve my problem?
Thanks for your time
Chris

Without seeing your code to walk through and duplicate the directory tree, there is no way anyone can solve your problem. But, I will tell you that your not setting the current directory properly on the copy your making. Remember "CD .." changes the current directory to its parent.
FTP does not allow for transfering of an entire directory structure. Your application has to walk the tree and rebuild it itself.

Hey,
Thanks i have emailed you the code, was a bit much to post here.
Thanks for your time

I've got it, but in the future, post the code here, not to my personal email. I've barely got any time to do stuff with my girlfriend let alone look at everyones code that sends it directly too me. Besides, posting it here will give other people a chance to take a look at your problem in the event I go on vacation and ignore my Inbox and work life for a week or two...

I seriously doubt any translator exists. Simply because C++ is a much lower level language that does not translate statement for statement to any flavor of VB. What VB does in one statement can take C++ an entire page. On top of that, VB doesn't have to ultimate flexibility C++ does.

I am trying to make an OCR .what should be the code in VB for removing noise levels from a document.
|
|
|
|
|
OCR in VB. ROTFL
You can see some noise removal filters in my image processing code articles, assuming you're using VB.NET, and assuming it has the same capabiities as C#. If not, you'll need to move to an actual programming language to do this with any degree of efficiency.

I am trying to build a web service that takes input parameters and enters them into an Arena simulation package..Once the simulation runs to the end..it enters output into a database...the field value from the DB is returned as an output by the webservice...

Dim amod = simobj.Modules
Dim bmod = simobj.Modules
amod = simobj.Modules(i)

simobj.Close()
'Open the Access DB of the model and get the value of output
Dim res As Double
Dim hit As Access.Application

Dim rs1 As DAO.Field
rs1 = rs.Fields("Value")
res = rs1.Value
Return res

Hello,
I've hit a brick wall and can't find ANYTHING to help me!
I'm creating an Object which has a method that returns a Collection object. This is fine until I want to pass it to a Webservice... then I get the following error...
You must implement the Add(System.Object) method on Microsoft.VisualBasic.Collection because it inherits from ICollection.
Here is an example of my code:
--------------------------------------------------------
Public Class History
Private m_colHistory As New Collection()
Public ReadOnly Property Entries() As Collection
Get
Return m_colHistory
End Get
End Property
Public Sub Add(ByVal Value As HistoryEntry)
m_colHistory.Add(Value)
End Sub
End Class
--------------------------------------------------------
I need to solve this urgently, any will be hugely appreciated!!
Many thanks
Richard

erm... perhaps you could do what the error is telling you to do ?
Public Sub Add(ByVal Value As Object)
m_colHistory.Add(Value)
End Sub

Have you tried using a different data structure, perhaps an ArrayList?

This is my first time deploying a windows application. I am able to deploy it correctly but I need some help with deploying it to a computer which doesn't have the .net framework installed.
I am using visual studio 2002 with framework 1.0.
Most example's only explain the framework 1.1.
How is this done?
Thanks

The machine you deploy your application to must have the Framework installed. The method of installation hasn't changed between 1.0 and 1.1. The examples you found for 1.1 will work with the 1.0 Framework.

How do I check to see if it does and if it doesn't install framework 1.0?
Dotnetfx.exe can be redistributed with your setup. How do you do this?
Thanks

It's called "bootstrapping". You can't include the .NET Redistributable in the .MSI that contains your application because one of the pre-launch conditions for install is that the .NET Framework already be installed! So, you must use a non-.NET managed application as a Setup program to check for the required software that must be installed, and unpackage and launch the appropriate installers for them, then, lastly, launch the .MSI setup for your application.
See this[^] excellent article on CodeProject for an example and explanation.
