hello..
this is the first time i'm developing client-server application
using VB and SQL server
now i'm testing the application with my server
the connection made with SQL Server using this
"Provider=SQLOLEDB.1;Persist Security Info=False;User ID=sa;Initial Catalog=dbDesa;Data Source=MSSYA"
the application will be ok in stand alone mode
i need to deploy the complete application to another server
so i assumed, the connection string above can't be used if the application install in another server
can somebody help me with the simple example to solve this

In my opinion, The Initial Catalog won't change but the Data Source might change base on the server name for each machine. As far as I know (local) variable is use to represent for each server name.

So your code should become to:
"Provider=SQLOLEDB.Persist Security Info=False;User ID=sa;Initial Catalog=dbDesa;Data Source=(local)" or "Provider=SQLOLEDB.Persist Security Info=False;User ID=sa;Initial Catalog=dbDesa;Data Source=local"
Try to check at http://www.connectionstrings.com/[^] for more information. For your database in sql server try use sp_detach_db and sp_attach_db store procedure to deploy it to the other machine. If you have SQL server book online then you can choose have a look at it for reference.

A more typical way to represent it would be to use Data Source=..
Having said that, if it's a client / server app, then it's unlikely that the datasource will be the local machine. What I typically do is form a connection string dynamically based on settings (usually stored in the registry), with a UI to allow Dumb users to sort it out. If i'm dealing with techies, I tend to use the Datalinks dialog for configuring connections:
<br />
Dim oDL as New Datalinks<br />
<br />
strConnectionString = oDL.PromptNew<br />
oConnection.Open strConnectionString<br />
<br />
which displays the DL dlg and returns the conn string - useful if not sure what users want to connect to, but does allow them to do silly things like form a conn string for Oracle on the local host, when they need SQLServer on a remote machine...but like I said - tend to reserve that for savvy users! Note that given a ADODB::Connection object, can also call PromptEdit, which makes the dlg default to the current settings....
In terms of deploying the DB, I tend not to use attach and detatch, but rather backup and restore to a different machine, or SQL Script the whole smash - swings and roundabouts really, but my preference....

Yes, I also concern about this problem before. But now I have to make sure that the user choose the correct database. To do that, I have to check the structure of the database (the number of table and number fields) after the user have select the database. If it is wrong then let the user to choose another one.

Hello It's me again with another painstaking question. I am still working on the same database (In Access 2000) and am now trying to import an excel file. My problem is that the excel file has some special formating and extra crap I don't need and do not know how to get around, so it doesn't import. If need be I can email the excel file to anyone willing to help me. This excel file is updated by a third party every week so it will be an on going import and I would like to make it as easy as possible to do. I'm sorry I'm not to detailed it's a bit hard to explain without one seeing what I am trying to do.
If you would like me to email you the excel file please email me @

Using the following code:
Private Sub LkSplitsGrid1_DragEnter(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles LkSplitsGrid1.DragEnter<br />
If e.Data.GetDataPresent(DRAGITEM) Then<br />
e.Effect = DragDropEffects.Copy '(A)<br />
ElseIf e.Data.GetDataPresent(DRAGELEMENT) Then<br />
Try<br />
Dim c As LKVariable = CType(e.Data.GetData(DRAGELEMENT), LKVariable)<br />
e.Effect = DragDropEffects.Move '(B)<br />
Catch<br />
e.Effect = DragDropEffects.None<br />
End Try<br />
Else<br />
e.Effect = DragDropEffects.None<br />
End If<br />
End Sub
I wish to have the DragDropEffects to be set to "move" but if I set the first instance of it (A) to "move" the cursor won't change. If I set (A) to "copy" and (B) to "copy" the (B) code doesn't change the cursor, ie. it is is the "none" cursor. Why is that?

When you initiated the drag drop operation with the DoDragDrop, what effect(s) did you specify?
Cheers

Hi.
I am just involved in writing a program (MUST BE IN VB6) that works with access databases.
I know what to do in order to get, set or update data.
My problem is to print some reports from the data.
I don't know wether I should make the report and it's form to be printed myself or there is some methods to generate a report like what is in access itself.
Thanks in advance

You could use the Data Report Designer.
If you use the Data Environment Designer to set up the data source, you can use the Report Designer to lay out the design of the report.
You would need the Add Data Report to appear on the Project menu. If it doesn't, do the following...
Open Components dialog box, click Designers tab, select Data Report.
Once you add the Data Report to your project, all you have to do is set its properties.
I hope this helps.

I have tried ever thing under the sun and the moon and I don't get I am trying to write a code that counts the number charcters, number of words, number of sentences, and number paragrahgs contained in a string.
|
|
|
|

Huh?
Guess not understood your problem exactly, but:
using Len() function, you can find out number of characters inside a string. counting number of dots (.) you can find the number of sentences. counting the number of enters (chr(13)) you can find number of paragraphs.
(just there should be some verifications to see for example if a dot (.) is a dot in a number (2.34) or not or some other things. and it is easy to check)
I dunno if I have answered your question or not!

I’m having a hard time manipulating a string...
How can I remove everything to the left of a given string in a string?
Example:
‘This is my main string. It is always different’.
I want to trim everything to the left of ‘string.’ Including ‘string.’ So that my new string reads:
‘It is always different.’
The word ‘string.’ will always be part of the string.
Thanks
Brad

Hey
You can use this
Dim i As String = "This is my main string. It is always different"
Dim a() As String
a = i.Split("string.")
a(0) = "This is my main"
a(1) = "It is always different"
The string you then need is a(1)
Have a look at this[^] article
Hope this helps

Hi Chris.
I actually tried that but instead of splitting the string at 'string.' it splits it every time it finds one of the letters in 'string.' I thought it was a simple concept until I started trying to use 'split' to make it work.
Thanks.

I have the following code, but I cannot seem to get the changes in the dataset to be commited to the database. All I get is a 0 rowcount:
Private editQry As String = "select idc,nomiko,Eponymo,Onoma,Tel from Persons where idc=1"
Private adoCEDataAdapter As SqlCeDataAdapter
Private CustEditDataSet As DataSet
Private cb As SqlCeCommandBuilder
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.Close()
End Sub
Private Sub frmCustEdit_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
adoCEDataAdapter = New SqlCeDataAdapter(editQry, frmConnect.adocon)
cb = New SqlCeCommandBuilder(adoCEDataAdapter)
CustEditDataSet = New DataSet
adoCEDataAdapter.Fill(CustEditDataSet)
txtSurname.DataBindings.Add(New Binding("Text", CustEditDataSet.Tables(0), "Eponymo"))
txtName.DataBindings.Add(New Binding("Text", CustEditDataSet.Tables(0), "Onoma"))
txtTel.DataBindings.Add(New Binding("Text", CustEditDataSet.Tables(0), "Tel"))
cbLegal.DataBindings.Add(New Binding("SelectedIndex", CustEditDataSet.Tables(0), "nomiko"))
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
MsgBox(adoCEDataAdapter.Update(CustEditDataSet).ToString())
Me.Close()
End Sub
I have tried to create the Update query with:
adoCEDataAdapter.UpdateCommand=cb.GetUpdateCommand
and it returns a query, but again nothing happens on the adoCEDataAdapter.Update(CustEditDataSet)
Help....

Hi,
Is there a way to run a program when a cd is put in the drive using either vb 6 or vb.net. I am not looking to autorun the cd.
|
|
|
|
|
This is something that is on my “To Do” list also. I want to make a CD Autorun an html file that is located on the CD but I haven’t had time to look into it yet.
The first thing that I was going to do was check to see if I could make an AutoRun.ini file that points to my html file. Maybe this same concept will work if you direct the AutoRun.ini to your programs exe file.

Hi,
Actually what I want to do is a little different. I have cds that are already made and I want a windows based program to run when a cd is inserted into the drive. I cannot put anything else on to the cd. I need to start a program of my own. Its a bit like when you put a cd in when using Windows XP. A window is displayed asking you what you want to do ie play it or do nothing. Except I will be running the program under windows nt and windows 2000. Hope I've made scense

Hmmm....now I understand exactly what you want to do but I’m not sure how to make it happen.
There are some very intelligent people in this User Group. Hopefully someone will have an answer for you.
If I find any useful information while I’m trying to figure out how to AuotRun my html I'll let you know.
