Hi all!
I've Run into a problem in developing my latest VB App, how would you launch a console
window from a winform and write to and read from it using vb's ReadLine() and WriteLine()?
This is what i have so far:
Dim OutputConsole As Console
... Yep, that's it, i can't figure out how to actually show the console window, even thougn ( I think), it is actually there.
Thanks

Hi,
I know of no way to add a visible Console to a Windows app.
AFAIK the only (easy) way to get a Console is by creating a "Console Application", which always
has a Console (which can be hidden after it has been shown initially) and which can
or can not behave as a regular Windows app, depending on your code.

Hi Again!
Thanks for your help, maybe i'll dress up a winform to look like a console window and
add a keylistener to run commands.
Thanks Again

Dim params() As SqlParameter = {New SqlParameter("@pfaAccount", pfaAccount), _
New SqlParameter("@fileName", myfileName), _
New SqlParameter("@sent", sent), _
New SqlParameter("@FullPath", dNfNme)}

I Don't like to debug Windows Services, therefore I always create seperate classes with all functionality I need and the test those on and on before calling the functions in those classes from a windows service.
|
|
|
|
|
i have include change integrated security but the problem persist. the connection string is
Dim con As New SqlConnection("Data Source=PRGLAP11;Initial Catalog=diamonddb;username = sa; password = eb")

If you put an stop statemnt in your code it should ask if you want to open the app in a debugger. Alternativly put a thread.sleep (for about 15 seconds) in the onstart code (to make your code wait) and attach to the process from the debug menu of the ide.
Hope this helps

when i put the thread it tell it cannot start the service. if i comment out the tread line and set break point at sub process mail. the service will start but when i point at break. i see a tooltip." the breakpoint will not currently be hit. no symbol have been loaded for this document.
pls hlp see the extract code below
Public Class testService
Private t As Timer
Dim log As New EventLog("Application", ".", "Diamond eMail Solution")
Dim cr, KeyID, sKeyID As Int32, afterLoad As Boolean
Dim panelIndex As Int32, insert As Boolean, ds As DataSet, bllclass As New baseTables, bllAdmin As New Administration
Dim myfileName As String
Protected Overrides Sub OnStart(ByVal args() As String)
' Add code here to start your service. This method should set things
' in motion so your service can do its work.
System.Threading.Thread.Sleep(15000)
Try
t = New Timer(2000)
AddHandler t.Elapsed, AddressOf TimerFired
With t
.AutoReset = True
.Enabled = True
.Start()
End With
Catch ex As Exception
log.WriteEntry(ex.Message, EventLogEntryType.Information)
End Try
End Sub
Protected Overrides Sub OnStop()
' Add code here to perform any tear-down necessary to stop your service.
t.Stop()
t.Dispose()
End Sub
'Protected Overrides Sub OnPause()
' t.Stop()
' MyBase.OnPause()
'End Sub
Private Sub TimerFired(ByVal sender As Object, ByVal e As ElapsedEventArgs)
'Working()
'getApplicationData()
ProcessMail()
End Sub
Sub ProcessMail()
'Try
Dim insert As Boolean
Dim dailydirobj As DirectoryInfo = Directory.CreateDirectory("C:\ebube")
Dim ins As String = "INSERT INTO incoming([pfaAccount] ,[fileName], sent,FullPath) VALUES('ebube','fileName','0' ,'FullPath')"
Dim con As New SqlConnection("Data Source=PRGLAP11;Initial Catalog=diamonddb;Integrated Security=SSPI")
Dim com As New SqlCommand(ins, con)
con.Open()
com.ExecuteNonQuery()
con.Close()
end sub
end class

You cannot debug a windows service directly from the ide as you cannot run a service from the ide. Install the service, then ATTACH from the debug menu.

that is exactly what i deed

I can't tell because you didn't post the connection string, but the common problem in connecting to an SQL Server from a Windows Service is using Integrated Security. The Local System account has no permissions to SQL Server, so the connection will not work.
Best practice is to NOT use integrated security, unless absolutely necessary and, instead, create a user account in SQL Server that the Service will use to connect to SQL Server. This gives you much greater control over what that account can and cannot do in SQL, resulting in greater security of your data.

i have included account and problem persist.
|
|
|
|
|
When you added the username and password to your connection string, did you ALSO remove the Integrated Security option from it??

Can I execute an exe in a windows application ? My exact requirement is,
on the button click event I should run the exe in the same window where the button resides. Right now I am using process.start() to execute, but it is opening a new window.
Thank U all,
Kiran

There is a CP article on this. It's a real hack ,but you can do something. Odds are you're going to break your app tho, I would not do it.

Hi,
Please forgive my lack of knowledge and this silly question. I would like to replace the (#?#) in the input string "5#A# 10#B#", to make it look like "5? 10?" and then display it in a richtextbox.
(the ? marks above should be the figures in the title)
Is this possible? can anybody teach me how to?
Thanks a lot!
Joe

You might want to look at regular expressions on this, also for the heart, diamond, club, and spade characters, look in the symbols font and supply the ascii code for them in your regular expression.

Hi Paul,
Thanks for the tip! I will look into it. A few hours ago I just tried setting the font of the control to one that supports unicode to see what happends, and "Presto" I got the figures I needed.
Once again, thanks for your time. I will really look into it.
Joe.

I am actually suprised you got the symbols to show up correctly in the title, I thought their were web limitations preventing them.
