Your question doesn't make any sense and I'm not installing a downloader from that site to see your image.
Post your image on a site like Flickr and rewrite your post so it makes sense and you might get somewhere.
Oh, and you might want to drop all VB6 development and move up to something that hasn't been dead for over 7 years now, like .NET.

Hi Friends
I'm working on a project that Read & Write from COM ports.
http://s2.picofile.com/file/7680529565/03_05_2013_11_44_28_%D8%A8_%D8%B8.jpg
But i have some problems!
I define a thread in a Buttom to read from Port in Background because when i send a text to port and other device did'nt send any thing the program become hang!!
therefore :
Dim t As New Threading.Thread(AddressOf Recieve_Data)
t.IsBackground = True
t.Start()
and Recieve_Data():
Sub Recieve_Data()
While True
associatedChar = ChrW(SerialPort1.ReadByte)
RichTextBox2.Text &= SerialPort1.ReadExisting & " " & CStr(Now) & vbCrLf
RichTextBox2.SelectionStart = RichTextBox2.TextLength
RichTextBox2.ScrollToCaret()
End While
End Sub
but when i run project i receive this error:

You are trying to access your Richtextbox from within a thread which isn't allowed, you need to create a delegate to make it happen
have a read of this

Hi,
I developed vb6 application it is working fine in win xp,win 2003 but not running win 7(64-bit). It threw following error popup.
Component
after received this error i placed
system32 floder that OCX in win7(64bit) again it threw error popup
The module "mscomct2.ocx" may not compatible with the version of Windows that you
what i do. please help me.

|

You don't put it in System32 on a 64-bit system.
It goes in the C:\Windows\SysWow64 folder and has to be registered using REGSVR.
As for that compatibility warning message, if you continue to use VB6, you will see more and more of it as VB6 has been dead for ... lets see now ... 7 years. I HIGHLY suggest you abandon all VB6 developement and move to VB.NET. You can get a free version here[^]

Congratulations on picking a project. Please, proceed!
ooorrrrr did you have a question you meant to ask, but didn't?
|
|
|
|
|
Yes , it is a question ??
|
|
|
|
|
No, it isn't. It's a statement of what you want to do.
The question would be a description of the problem you're having, which you haven't provided.

Hi ppl,
I have a vb6.0 application working with sql 2005 service. we have planned to refresh the sql service to sql 2012.I am not sure of how far vb6 is compatible with sql2012. It would be great if someone could let me know whether vb6 compatible with sql2012 server.
Can anybody here share the problem they faced after the such migration.

The question is pointless. Neither has any direct impact on the other as VB6 doesn't know what an SQL Server is and SQL Server doesn't give a rats ass what programming language was used to generate the query that it's executing.
So, yes, it'll work.

I need to update an old project, which has all the files, .vb, .resx, .designer.vb, .dll, .vshost,.exe ... in one folder.
So I wonder if I can create a new project, and create new directory architecture, like: src/UI; src/DAL, src/BLL, Res/icon,
Then copy the files from old project folder to the new folder.
for now, I find I can't use "add existing item" to add .resx to the new project.
Then I try to just create new folders in the old project and move the files to new folder,don't know if this way works or not.
Could anybody give me some advices?
Thanks

Now I know I can rearrange the files into new created folders in old project.

I tried to use a string var, like aStr & VBC_VER,but the IDE show
error mark on VBC_VER.
I know VBC_VER is a conditional compilation constant, so can I print the constant on console or msgbox()?

It can't be printed like a string, since it's not a variable. Try something like below;
Dim bla As String
#If VBC_VER >= 9.0 Then
bla = "9+"
#Else
bla = "8 or lower"
#End If
Console.WriteLine(bla)

Thanks, then it is not possible just output VBC_VER?
like: printf("%s\n", VBC_VER)?
|
|
|
|

No.

No, because the compile-time constants won't exist at run-time. They are not variable, nor are they replacement strings that will show up in your code.

Good Morning,
I am new to this forum, so hello, world!
I am attempting to read the following from a text file and turn each line into a separate array...
MIA JFK HNL LAX DFW
-5 -5 -10 -8 -6
0 3 12 8 2.5
3 0 14 8.5 3.5
12 12 0 4.5 8.5
8 8.5 4.5 0 3.5
2.5 3.5 8.5 3.5 0
Ideally the first line would be inserted into an array like {MIA,JFK,HNL,LAX,DFW}
Second line a new array with {-4, -4, -10, -7, -5}
And the last lines would be inserted into a two dimensional array:
{{0, 3, 12, 8, 2.5}, _
{3, 0, 14, 8.5, 3.5}, _
{12, 14, 0, 4.5, 8.5}, _
{8, 8.5, 4.5, 0, 3.5}, _
{2.5, 3.5, 8.5, 3.5, 0}}
I have been struggling for over two days with this. This solution is probably easy... but it is evading me. I have tried using the streamreader to no avail.
Here is something I tried...
Public Class Form1
Dim tmpArray() As String
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Try
Dim sr As New StreamReader("..\..\info1.txt")
Dim count As Integer = 0
While Not sr.EndOfStream
Dim line As String = Nothing
line = sr.ReadToEnd()
tmpArray() = line.Split(" ")
End While
Catch ex As Exception
End Try
End Sub
End Class
Any help would be greatly appreciated.
