Thanks for ur reply..
But it is not working and give an error "No user defined UInt32" data type exist.
Can u help me how to find max length of UInt32??
|
|
|
|
|
System.UInt32.MaxValue
which is 4,294,967,295. The problem with using UInt32 is that it's not CLS-compliant, so you might get some warnings about that.
|
|
|
|
|
Actually problem may be that I am using VB 6.0 and there is no UInt32 data type.
Is it correct??
|
|
|
|
|
yes.
if you are enquiring about VB6 you should put "VB6" in your message and subject line. Always.
|
|
|
|

Yep. VB6 has no unsigned integer data types and doesn't have an integer type that supports a number that large. So, it's appending the "#" character to the number to force it to be treated as a Double, which is a floating point type.
I highly suggest abandoning any new developement in VB6 and move to VB.NET.

Hi,
I am able to extract the text from the PDF file using the PDFStripper, but I would like to read the Table of content of the PDF document. How can I do that? How do I know the Page I am reading is Table of Contents? and also how to differentiate the Chapter heading and the subsection of chapter of the Table of Content?
Any help in this is highly appreciated.
Thanks
Neil

I have found a code from the net, but its not working properly.
It is related to UDP socket creation.
Senario is like when we click on "send data" button a "hello" string should pass from client to server which are on the same machine.
Problem is when I click on "send data" button it gives an error-
code is-
Private Sub Form_Load()
' Set the control objects when the form loads.
Set wsClient = Me!axWinsockClient.Object
Set wsServer = Me!axWinsockServer.Object
' Set the protocol for client and server.
wsClient.Protocol = sckUDPProtocol
wsServer.Protocol = sckUDPProtocol
' Set the host and ports for client and server. Because client
' and server are the same computer in this example, set RemoteHost
' equal to LocalIP.
wsServer.RemoteHost = wsClient.LocalIP
wsServer.RemotePort = 1007
wsClient.Bind 1007
End Sub
Private Sub CmdSend_Click()
' Send a broadcast message from the server.
wsServer.SendData "Hello"
End Sub
Private Sub axWinsockClient_DataArrival(ByVal bytesTotal As Long)
Dim strServerMsg As String
' When a message arrives from the server, display it in a text
' box.
wsClient.GetData strServerMsg, vbString
Me!Text1.Value = strServerMsg
End Sub
Here axWinsockClient and axWinsockServer are the socket control or winsock on the same form. and "hello" string should be print in text box.
On debugging I found it is not calling axWinsockClient_DataArrival() method.
What may be the problem.
Thnks in adv..

You left out the most important part of the question. WHAT'S THE ERROR YOU'RE GETTING??
|
|
|
|
|
|
Perhaps you should post what the error was and what you did to fix it so that other people with the same problem can benefit from your post

Give him a break, he was just reminded about errors.

Somehow, I doubt it. If all it took was to read the eorror message, I think the solution was obvious from whatever the message was.

Yeah good point, sorry

Hi, dear all,
I create a database using Access database.
There are some fields with data type Yes/No, I want to know to tell the difference of Null and False.
Right now even if I never set value for these field, they return false to me. I wants to clarify the difference.
I use the following code, but doesn't work, suppose I have a field called Marriage which is type Yes/No.
if user never fill in value for it, it should return Null, otherwise, return true or false
Dim obj as Object
obj = ResultSet.Tables(0).Rows(0).Item("Marriage")
If IsDBNull(obj) Then
return Nothing
ElseIf obj.ToString() = "True" Then
return True
Else
return False
End If
it always reutrn "False" to me.
Thanks!

I hope you were smart enough and googled your question. an adequate suggestion is readily available.
|
|
|
|
|
I search from google first, but didn't find any answer.
|
|
|
|
|
for decimal data type, everything is ok, only for Yes/No data type, if you didn't set value for it, it return False to you.
|
|
|
|
|
That is correct; if you don't like it, use something else.

In my program there is a function that loops through a list of files, opens each file, reads the contents, and then needs to output an excel file that contains the data plus additional notes that is determines from the data. The loop is something like this (overly simplified though)
Private Function ProcessFiles()
Dim FilesToProcess as List(Of String)
PopulateList(FilesToProcess)
For Each item As String in FilesToProcess
Dim fs As New FileStream(item)
Dim Data As String = fs.ReadToEnd
...
...
...
Next
End Function
In my program this is probably the function that takes the longest to complete and I feel that it might benefit from parallelization and would like to run some benchmarks. However I'm having trouble understanding how to implement the parallelization.
From what I've gathered so far I might be able to do something like this:
Private Function ProcessFiles()
Dim FilesToProcess as List(Of String)
PopulateList(FilesToProcess)
Parallel.ForEach(FilesToProcess ???)
Dim fs As New FileStream(item)
Dim Data As String = fs.ReadToEnd
...
...
...
Next
End Function
Not sure how to write the rest of the Parallel.ForEach. Any help would be greatly appreciated. Thanks in advance.

You can do this, but since you're using Excel in this loop, you may have just stopped this from working. You'll have to test to see if you can do this work in Excel from multiple threads at the same time. I don't think it'll work, but that's what testing is for...

I am creating Excel files, but I'm not using Interop. I have a third-party library that will let me create Excel files without Excel being installed on the workstation so this shouldn't be a problem.
