How can I create tables,store procedure, and trigger using vb 2008 installer class during apps installation
|

Don't forget your any indexes you may have built.
|
|
|
|
|
This is normally done by running create scripts during the installation.

Is there any way to identify an event that came to an end,
that the event arrived at the End Sub?
Sorry for the misspelled because I can not speak English and used a translator to help me
Thank you

Only if you put code in the end of the Sub that signals this in some way.
|
|
|
|
|
What I need to do is something like this
Private Sub btn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn.Click
Here runs a function that checks if the btn.Click comes to an end and shoot another routine but this routine can only be triggered when the event comes to an end btn.Click Ex: after the end Sub
End Sub
|
|
|
|
|
Soooooo, in a single threaded environment, this is incredibly easy. Just call the method as the last line of your Click handler. That's a horrible button name, by the way.
Private Sub btn_Click(blah, blah) Handles btn.Click
...some code...
MyOtherMethod()
End Sub
|
|
|
|
|
Ok kkkk promise to fix the name of Button.
But I still have doubts is like MyOtherMethod () to do the check when Private Sub btn_Click (blah, blah) Handles btn.Click end its process
I'm trying to do is this
1 - click on the button
2 - click on the button triggers the event Private Sub btn_Click (blah, blah) Handles btn.Click
3 - The btn.Click event triggers the routine MyOtherMethod () the btn.Click however, have to continue running the remaining code
4 - MyOtherMethod () loop is waiting for the end of btn.Click
5 - When the event finished btn.Click, MyOtherMethod () loop that identifies that event ended btn.Click and runs a code that is out of the loop and ends
What i am not able to do is, call event btn.Click MyOtherMethod () and continue running the rest of the code, which waits btn.Click MyOtherMethod () finish to continue
and also I am not able to make the MyOtherMethod () identifies which ended btn.Click
thank you

OK, you didn't get it. There is NO other code after the call to MyOtherMethod. That is the last thing that happens inside the event handler.
I serisouly doubt you need to go call some method, then have it wait on the rest of the code in the handler to finish. It WILL NOT ever finish until the method you called finishes itself.
It sounds as though you need to restructure what you're doing, synchronously, to avoid this situation. When you make a method call, the code that does the calling does NOT continue to run while the method is executing. The calling code completely stops and waits for the method called to return. This is called a "blocking call".
Also, event handlers should return inside of about 250 milliseconds. While your event handler code is exectuing, your UI is copmletely hung waiting for it. The user cannot click on anything in your app until the handler returns.
But, in any case, the ONLY way to do what you describe to is use threading and a WaitHandle to signal the other thread. So, your event handler gets called, and in it you kick off another thread.
What are you doing that you think you need to do this??

Hello everyone:
I need guidance on how to start with this small project.
I need to implement a web interface that will access applications that developed in vb.net with sql back end.
What I mean is the following:
I have two small applications, one is fire arms registration and the other is logistic.
Both apps reside on the same sql server.
I want to have a web interface that will point to each one base on the user access.
that is if the user is from fire arm than fire arm registration app will launch and so on..
of course this can for a number of applications.
The general purpose of this, is to have access to these applications via the web.
what best solution to use in order to accomplish this task.
I would like to know what i need to consider first in all aspect of this task.
Thanks in advance for your guidance and help.

What do you mean 'access applications'? You want to give a WEB UI to it or launch an exe? If launch then, since it's a web interface, exe needs to be downloaded to client system and then launched. If you do a process.start on server, it will not be on client system and they will now see/know.

Thanks for reply:
I want to give a WEB UI to it. All the user ought to do is to simply log in through a web interface.
Be mindful the application is an executable, it can be installed on a client machine.
For the WEB UI, it will be installed on the server.
The application can be accessed directly on the server or through the WEB UI.
I do not want to user to download anything. Simply login and based on his/her login ID will determine which application that will launch.
Once again thank you.

Launch where? On client or server?
If server, what's the use?
If client, you understand that it has to be downloaded on client system and then installed to be used.

Thanks again
On the server

hi
your feedback will be appreciated.
thanks

Well, I was waiting for your full response.
I did asked this too: If server, what's the use?
Can you share the expected workflow from logging in to returning back something to user.
I get that one executable needs to be picked, what after that, what role does it play and how does client come to know/use it. Since it will not be downloaded and will be launched on server side, what are you trying achieve?

Thanks again,
This is what I want to accomplish:
Let's say I have two applications developed in vb.net with sql as database namely fire arms registration and vehicle registration respectively.
these two applications centrally reside on the same server. i want to allow authorized user to access these application through a WEB UI.
For example, if I am way from the office location and I need to use any one of these apps, I can simply login to a web interface and perform any operation i so desire as long I have access privilege.
These applications are executable. it can be installed on a client machine as they are being deployed right now.
there is a need to have these apps available through an URL...
I hope that I am a little clearer now and you can have an idea of my train of thought and process.
Thanks a lot.

ASP.NET
Still sounds like a trick-question. You'd have to write a Web-UI.
Or use something like Citrix.

The messages are put into the Inbox i just cant display the body of the message in the richtext box when selected from the listbox. Any Help will be greatly appreciated! Thanks!
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
Dim strMailServer, strUsername, strPassword, strFrom, strSubject, strToo, strBody, strMailContent As String
Dim popConn As Text_Me_Now.POP3
Dim mailMess As Text_Me_Now.EmailMessage
Dim intMessCnt, i As Integer
strMailServer = "pop.gmx.com"
strUsername = "xxxxxxx@gmx.com"
strPassword = "xxxxxxx"
Button2.Enabled = False
popConn = New Text_Me_Now.POP3
mailMess = New Text_Me_Now.EmailMessage
popConn.POPConnect(strMailServer, strUsername, strPassword)
intMessCnt = popConn.GetMailStat()
If intMessCnt > 0 Then
ListBox1.Items.Clear()
For i = 1 To intMessCnt
strMailContent = popConn.GetMailMessage(i)
strFrom = mailMess.ParseEmail(strMailContent, "From:")
strSubject = mailMess.ParseEmail(strMailContent, "Subject:")
strToo = mailMess.ParseEmail(strMailContent, "To:")
strBody = mailMess.ParseBody()
ListBox1.Items.Add(strFrom & ", " & strSubject)
Next i
End If
popConn.CloseConn()
Button2.Enabled = True
End Sub
Private Sub ListBox1_SelectedIndexChanged(sender As Object,
End Sub

You appear to have extracted all the relevant information for the message, but the only thing you are storing in the ListBox items collection is the from and and subject parts as a single string.
ListBox1.Items.Add(strFrom & ", " & strSubject)
I would suggest that instead of storing this string, that you instead define a class to hold the relevant information.
Something like this:
Public Class MessageItem
Public From As String
Public Body As String
Public Subject As String
Public Sub New(ByVal From As String, ByVal Subject As String, ByVal Body As String)
Me.From = From
Me.Body = Body
Me.Subject = Subject
End Sub
Public Overrides Function ToString() As String
Return From & ", " & Subject
End Function
End Class
Instead of adding items directly to the ListBox, you bind the ListBox to a List(of MessageItem). Define this list at the form level like this:
Private Messages As New List(Of MessageItem)
In the FormLoad event handler, place this statement:
ListBox1.DataSource = Messages
The ToString Function defined in the class will provide the text displayed for the item in the ListBox.
Now in your button_click handler, replace this code:
'call the functions to get the various parts out of the email
strFrom = mailMess.ParseEmail(strMailContent, "From:")
strSubject = mailMess.ParseEmail(strMailContent, "Subject:")
strToo = mailMess.ParseEmail(strMailContent, "To:")
strBody = mailMess.ParseBody()
'add email details to the list box
ListBox1.Items.Add(strFrom & ", " & strSubject)
with this:
Dim msg As New MessageItem(mailMess.ParseEmail(strMailContent, "From:"), _
mailMess.ParseEmail(strMailContent, "Subject:"), _
mailMess.ParseBody())
Messages.Add(msg)
Also replace ListBox1.Items.Clear() with Messages.Clear()
Now in your ListBox1_SelectedIndexChanged method you can set the textbox text with something like this:
RichTextBox1.Text = CType(ListBox1.SelectedItem, MessageItem).Body
