Hi,
Can anyone please give me the code snippet in vb6 to check if MDAC is present on a machine and the MDAC version number if it is present.
Right now i have a code that checks the ADO version.
Here is the code:
Option Explicit
Function GetAdoVersion() As String
'Returns an empty string if ADO is not installed
Dim o As Object
On Error Resume Next
Set o = CreateObject("ADODB.Connection")
If Err.Number = 0 Then
GetAdoVersion = o.Version
Label1.Caption = "ADO Version = " & o.Version
Else
Label1.Caption = "ADO is not installed"
End If
End Function
Private Sub Form_Load()
Call GetAdoVersion
End Sub
Are ADO version and MDAC version the same always?
Thanks in advance,
Sarah

It's not that simple. No ADO and MDAC versions are NOT always the same. Various applications can install differing versions on their own, without installing the complete MDAC package.
There is no reliable way to determine whcih version your using. Component Checker[^] will scan your machine to determine which version of MDAC your machine has installed, or the closest match. It'll show you what pieces are missing and what's installed, as well as the version information for each .DLL.

I really cannot get into the DB story. Anyway this is what it happens.
I'm running VS2005 and MS SQL Server Express. I created a DB under the SQL server and it works. I filled the data manually (right click on the table and see table data) and it works.
At application start I load data into a dataset with the autocreated tableadabter fill method:
Dim ta As New RF_MapDataSetTableAdapters.VeicoliTableAdapter<br />
ta.Fill(dbVeicoli)
and it works beacuse the dataset contains the test rows I inserted manually.
Now I have a form to create a new record .. not directly linked but on the OK command click I:
Dim mVehicle As RF_MapDataSet.VeicoliRow<br />
'<br />
mvehicle = dbVeicoli.NewVeicoliRow<br />
mvehicle.ID = CreateID()<br />
mvehicle.Nome = txtNome.Text<br />
...and all the other fields...<br />
dbVeicoli.AddVeicoliRow(mvehicle)
And it works, in the sense that the dataset contains the new row and it's showed somewhere else in the app..... now on the main form closing I want to save the DB and according to documentation it should be very easy:
Dim ta As New RF_MapDataSetTableAdapters.VeicoliTableAdapter<br />
ta.Update(dbVeicoli)
Unfortunately it isn't beacuse the DB has still only the original, manually entered, records. Where do I go wrong?
I tried also another way. Rather than updating the dataset, I tried to create new records directly in the DB with this code:
Dim ta As New RF_MapDataSetTableAdapters.VeicoliTableAdapter<br />
'<br />
ta.Insert(CreateID(), txtNome.Text, txtModello.Text, _<br />
txtTipo.Text, txtAnno.Text, txtColore.Text, _<br />
txtTarga.Text, dtpInizio.Value, dtpFine.Value, _<br />
cmbDispositivo.SelectedIndex.ToString, _<br />
1, txtVoce.Text, txtDati.Text, dtpCreazione.Value, _<br />
txtLineaDati.Text, txtLineaSMS.Text, _<br />
txtLineaVoce.Text, Now, "", "", 0, 0, "", "", "", "", _<br />
"", "", 0, "")
but then again the DB is immaculate as before. It comes without saying that I get no exceptions ... so the code seems to work correctly with the DB.
What am I missing?

There is no need to post your question 4 times.
There are a number of ways to do what you want to do, but without knowing your skill level I can't provide you with any help. If you had a specific question I could probably easily help.
Completely and utterly guessing here.
Create a client side record set, when the client changes the grid or what ever update the database.
On the admin side, randomly pool the database for changes. Update the ui as needed.
That’s about the simplest way that I can think of off the top of my head.
The technologies you will need to know are VB and ADO, should be very easy…
And what is a Matrik? Could it be Matrix? For a "Matrix" you will need a grid of one sort or another, VB has two or three that are fairly easy to work with. When you get stuck feel free to ask a specific question.

Using the PerformanceCounter-Processor Time get the right reading when it's used with intel pentuim but it double the reading when it is used with intel pentuim HT?
why??

Read up on HyperThreading technology from www.intel.com[^].
Basically, an HT processor is (almost) equivalent to two.

With all due respect, I think you need to spend a little more time doing some basic research of your own.

counting the words in a file (txt, rtf, doc) after loading it to a RichTextBox differ than the counter in the MSWord...sometimes more, sometimes less...trying with many files...
with getting notice that the file type as a Rich Text Box Stream Type (ex: PlainText, UnicodePlainText or RichText)..
so, why this problem????!!!
i need help
Militiaware

Simple - they use different algorithms to determine the number of words. Choose one app and stick with it otherwise you're comparing apples with oranges.
...Steve

i'm sorry Mr. Pullan
but how two algorithms solve one problem and each of them give diffrent answer...
one of them should be right!
Thanx Steve

They are both right in their own way.
They count words differently from each other. There are many control codes in a Word document which are only interpreted correctly by Word itself. Any other program may consider the control characters themselves to be words or beginning of words or ending of words or garbage etc...
The only way to get a consistent answer is to use the application from which the file was created in the first place.

If you simply Google the title of your post - add checkbox control to a subitem in a listview - you'll get the answer you seek.
