I've reciently used a web service and needed to refernce the web service's dll inside the new application's project. This allowed me to:
Imports MyNamespace.com.webservices<br />
Dim _webdata As WebServices<br />
_webdata = new WebServices()
But you'll need to Add Web Reference to the project.

Hi,
This is very urgent. We are to deliver at month end at are struck at a point where, we ahve a weighing machine connected to my computer through a com port (COM1). Now, we are developing an application in vb 6.0 to read the weight that is placed on the weighing machine.
The problem is, the application is not fetching the value from the COM PORT and when it is fetching it is a junk data.
Can anyone give an idea where to find help or provide with any link or provide with any code?
Any help would be awesome...

You should check the comm event, something like the following:
mscomm1_OnComm()
Select Case MSComm1.CommEvent
Case comEvReceive ' Received RThreshold # of chars.
g_rcvd = g_rcvd & MSComm1.Input
End Select
end sub
Depending on what your scale is doing you may need to add some code to check for pauses in the code (like check to see how long it has been since g_rcvd has changed)
Regarding the "junk data" I am suspecting is is returning ASCII, of HEX binary data and you will need to translate it (Bin 2 hex, use Chr$ function or something like that), not all hex values have good ASCII charactors to represent them, so it looks like junk....
good luck...

Hi all.
I'm Alessio and I've still some problems with remoting.
I've got a server app and a client app.
The server app expose an obj by .net remoting and the client creates a reference to it.
From the client I can call all the remoting obj methods and all works fine (and I'm very happy).
BUT (there's always a "but"), one of these methods requires two parameters:
- a string
- a XmlDocument byref
I can't call this method because the XmlDocument I want to pass from client to server, isn't serialized.
So, how can I serialize it ?
I hope there will be someone who can help me, because if not, probably, next week, I will be a dead-man.
Thanx in advance
Alessio

This is the code to serialize an object (that is serializable)
Public Function sSerializeObject(ByVal oObject As Object) As String
Dim oSerializer As New XmlSerializer(oObject.GetType)
Dim oSR As New MemoryStream, bt() As Byte
Try
oSerializer.Serialize(oSR, oObject)
bt = oSR.GetBuffer
sSerializeObject= System.Text.Encoding.ASCII.GetString(bt)
oSR.Close()
oSR = Nothing
oSerializer = Nothing
Catch ex As Exception
MsgBox(ex.ToString)
End Try
End Function

Ok, but you say "This is the code to serialize an object (that is serializable)".
My object is a XmlDocument, and it doesn't implements the serializable interface.
So, is the better way pass as byref parameter a string (or a stream) and then parse it with "loadXml" method ?

If your using .net remoting like I know it, then BYREF is questionable. I don't think that's possible -- you may know more about that...
You can convert the xmldocument a string, pass it over to your server pc via tcp connection(stream) and then do a loadxml on the server and process it, then pass back the changes and then replace your document with the one the server returned...

I want to develop a software directory like the one you see in Snapfiles
I am just confused how i should design the database for that.
It has 2 levels of hierarchy. The first level there is Browser Tool, Communication,...
The second level is Bookmark Manager, Chat(IRC),Font Tools
(^^^ these r from the site)
I think i have create 3 tables for that. One for the first level, 2nd for the second level & the 3rd for the software listings.
I am going to use VB.net for front end. Not sure if i should access or sql server as the back end.
I just want the opinion as i am newbie & inexperienced.
If i am asking in the wrong place, pls guide me to the right place or atleats tell me how i can find the right place

Can anyone tell me if vb2005 has a function comparable to InvokeVerbEx("Print")?
I have a folder that contains a number of .pdf files. I would like to have my code print each one of the .pdf files. If I right click on the file and click 'print', acrobat opens, prints the file, and then closes the file. Acrobat stays open, which is fine. I just want to send the files to the printer.
Thanks in advance.

Search for hours....no success.
Post a question...find it in 10 minutes. Go figure.
Here is what I found in case anyone cares.
Dim p As New System.Diagnostics.ProcessStartInfo()
p.Verb = "print"
p.WindowStyle = ProcessWindowStyle.Hidden
p.FileName = "C:\filename.htm"
p.UseShellExecute = True
System.Diagnostics.Process.Start(p)

Hello, i have recently developed an application using the Windows Media Player ActiveX/SDK
I want to be able to load plugins available in Windows Media Player in my application, such as the Windows Live/MSN Messenger Status plugin, so when somebody listens to a music track in my application it would trigger the plugin to activate and work like it was in WMP.
I'm sure there is a simple procedure, but maybe i am overlooking it...
Please help
Thanks

I have two functions created, one that creates a zip folder which contains files and one that creates a backup folder. I need to know how to copy that zip folder to the backup folder.
Thanks!

JDS,
Dim oDir As DirectoryInfo,sZipPath as string,sBackupPath As String
sZipPath="c:\zip\"
sBackuppath="C:\backup\"
oDir = New DirectoryInfo(sZipPath)
For Each oFile As FileInfo In oDir.GetFiles
File.Copy(oFile.FullName, sBackuppath & oFile.Name, True)
Next
'copies all files from the zip directory to the backup directory and replaces if alread there...
Hope this helps

Here are my two functions that I call under button click:
Public Function CreateZip(ByVal source As String, ByVal destination As String) As Boolean
If (Not (File.Exists(source))) Then
Return False
End If
If (Not (Directory.Exists(destination))) Then
Return False
End If
Try
Dim fastZip As FastZip = New FastZip
fastZip.CreateZip(destination, source, True, "", "")
Catch
Return False
End Try
Return True
End Function
Public Sub Folder()
Dim dirName As String = DateTime.Now.ToString("MM_dd_yyyy hh.mm.ss")
Dim fullPath As String = Path.Combine("C:\Data Feeds\Backup\", dirName
If (Not (Directory.Exists(fullPath))) Then
Directory.CreateDirectory(fullPath)
ElseIf (Directory.Exists(fullPath)) Then
Directory.CreateDirectory(fullPath(2))
End If
End Sub
I want to know how to copy the destination folder to the fullPath folder when it is created.

Jds,
there doesn't seem to be a vb.net way that doesn't involve enumerating through all the folders and files. I can give you that code if you want it.
the quick way would be to do the following...
Dim fso As Object
fso = CreateObject("Scripting.FileSystemObject")
fso.CopyFolder("C:\test", "c:\temp\")
fso = Nothing
copies the folder "test" into c:\temp\ resulting in c:\temp\test\
|
|
|
|
|
I got the following error: Exception from HRESULT: 0x800A004C (CTL_E_PATHNOTFOUND)which highlighted this line of code: fso.CopyFolder("C:\test.zip", "C:\Data Feeds\Backup\").
Any ideas?

jds,
it looks like your trying to treat the file as a folder. the method copyfolder will only work with 2 folders (source/destination). your trying to make the zip file a folder (seemingly).
file.copy("c:\test.zip","C:\Data Feeds\Backup\test.zip",true) '<--should take care of the copying.
sorry-->my understanding is that you were trying to copy 1 directory and all it's subfolders into another.

Sorry,
I am trying to copy 1 directory and all it's subfolders into another. I already have the zip folder created with its folders and subfolders through code and I have the code to create a dated folder in another procedure which will be the backup folder. Once I click the button to create the zip folder I want the backup folder to be created containing that zippped folder.
Thanks!

I maybe way off but you seem to have the answer in your code that you gave. pass in the variable "fullPath" into your function that creates the zip as the destination
Dim dirName As String = DateTime.Now.ToString("MM_dd_yyyy hh.mm.ss")
Dim fullPath As String = Path.Combine("C:\Data Feeds\Backup\", dirName)
Dim fastZip As FastZip = New FastZip
fastZip.CreateZip(fullPath, source, True, "", "")
won't the create a zip of whatever the source is into fullpath?
|
|
|
|
|
No, that doesn't work. The "test.zip" folder is already located in c:\. Remember, these are two different sub procedures. I want that test.zip folder to be copied to the dated folder which I create with the code below as a backup:
Public Sub BackupFolder()
Dim dirName As String = DateTime.Now.ToString("MM_dd_yyyy hh.mm.ss")
Dim fullPath As String = Path.Combine("C:\Data Feeds\Backup\", dirName)
If (Not (Directory.Exists(fullPath))) Then
Directory.CreateDirectory(fullPath)
ElseIf (Directory.Exists(fullPath)) Then
Directory.CreateDirectory(fullPath(2))
End If
End Sub
Hope I explained this accuratley.

I think theres some confusion going on. Test.Zip is not a folder. You can't navigate through it and treat it like a folder in your code. It MUST be treated as a file. The only reason you can do so in Explorer is because there is a Shell extension giving you the illusion of a navigable file system in the ZIP file.
