You're can not pass an event. You can, however, pass an event arguments object, or EventArgs.
But, depending on what you're really trying to do with this, normally, the only thing that gets the eventargs is the event handler. The handler then picks out what pieces of information it needs and passes those processed pieces to other methods. You would just about never pass an entire eventargs object to a method that is, itself, not an event handler.

It looks like you're trying to raise an event, but the parameters in your header are confusing. What are you really trying to do with this code?? Why does this code exist?

I'm very new to vb.net 2005

Im now the next step of learning and want to connect a Microsort Access database to visual basic.net 2005.

I have tryed to follow an example in Microsoft Visual basic 2005 Reloaded book by Richard A. Johnson. But i'm not getting the same results as he's book?

I designed a database in microsoft access 2007, and saved it in formats 2007 & 2003. (I have tried both formats in tying to connect the database to VB.net 2005).

I connected the database using the 'add new Date Source' in the Data Source window in Visual Basic.net 2005. In the configuration wizard i selected Database, then i select 'new Connection', chose ' Microsoft Access Database File (OLE DB)' as the data source, then added my database. Tested the connection and then clicked 'next'. I saved a copy of the database, selected the database object i wanted in my dataset. I know have a datasource in Vb. I can view all the table and preview the data in the tables......all looking good.

I then click on the datasource and select 'Details', then drag the datasource over onto my vbform. All the fields are displayed ok. I also have a dataset, a bindingSource, a tableAdapter and a BindingNavigator at the bottom on my vbform.

The problem I have, is when I run the program, I can not display the data in the tables (fields)they are empty.

What part did I do wrong and how can I display the data in the database and display it in the vbForm?

Any help will be much appreciated.

Personally I never use the way you are setting up a connection. I find it shakey.

<br />
            ConnectionString = "Provider=" + Provider + "Driver=" + Driver + "Server=" + Server + "; Database=" + DB + "; UID=" + UserName + "; PWD=" + Password + ";Trusted_Connection=yes;"<br />
<br />
            queryString = "SELECT Names FROM MYTABLE"<br />
<br />
Try<br />
                Using connection As New OdbcConnection(ConnectionString)<br />
                    Dim command As New OdbcCommand(query, connection)<br />
                    connection.Open()<br />
<br />
                    Dim reader As OdbcDataReader = command.ExecuteReader()<br />
<br />
                    While reader.Read()<br />
                        StringArray(i) = reader(0).ToString<br />
                        i += 1<br />
                    End While<br />
<br />
                    connection.Close()<br />
                    reader.Close()<br />
                End Using<br />
            Catch ex As Exception<br />
                <br />
            End Try<br />

OK. First, read this[^], specifically, point number 4.

Noone is going to read all that code.

Without looking at your code, you're probably opening a connection to the top of a domain controller, and not the OU path that you want the objects created in. I'm willing to bet that your LDAP string looks something like:

LDAP://domainController

Correct??

Open the path you want the objects created in instead:

LDAP://OU=targetContainer,OU=parentContainer,OU=something,DC=domainName,DC=com

i want to implement if condition because i want to get users created in there respective OU.

if you take a look at the following code :

private void CmdCreate_Click(object sender, System.EventArgs e)
{
if (!this.IsValid())
return;

try
{
DotnetAD.ADAdminUser = this.TxtAdminUser.Text;
DotnetAD.ADAdminPassword = this.TxtAdminPassword.Text;
DotnetAD.ADFullPath = "LDAP://" + this.TxtDomainController.Text;
DotnetAD.ADServer = this.TxtDomain.Text;

DirectoryEntry user = DotnetAD.CreateNewUser(this.TxtUsername.Text);
if (user != null)
{
MessageBox.Show(this, "The user has been created.", "Create User");
user.Close();
user.Dispose();
}
else
MessageBox.Show(this, "Unable to create user.", "Create User");
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}

DirectoryEntry Description = DotnetAD.SetProperty(Description, "description", TxtDescription.Text);
if (OU1.Select=true)
{

try
{
// Bind to the OU1 container, add a new User.
DirectoryEntry de = new DirectoryEntry("LDAP://CN=OU1,DC=Testing,DC=com");
}
catch (Exception Exception1)
{
// If a COMException is thrown, then the following code example can catch the text of the error.
// For more information about handling COM exceptions, see Handling Errors.
System.Runtime.InteropServices.COMException COMEx =
(System.Runtime.InteropServices.COMException)Exception1;
Console.WriteLine(COMEx.ErrorCode);
}

//DirectoryEntry newGroup = de.Children.Add("CN=Sales", "group");newGroup.CommitChanges();
//DirectoryEntry newContact = de.Children.Add("CN=New Contact", "contact");newContact.CommitChanges();

}
if (OU2.Select = true)
{
try
{
// Bind to the OU2 container, add a new User.
DirectoryEntry de = new DirectoryEntry("LDAP://CN=OU2,DC=Testing,DC=com");
}
catch (Exception Exception1)
{
// If a COMException is thrown, then the following code example can catch the text of the error.
// For more information about handling COM exceptions, see Handling Errors.
System.Runtime.InteropServices.COMException COMEx =
(System.Runtime.InteropServices.COMException)Exception1;
Console.WriteLine(COMEx.ErrorCode);
}
//try
//{
// DirectoryEntry de = new DirectoryEntry("LDAP://CN=OU2,DC=Testing,DC=com");
//}

}
if (OU3.Select = true)
{
try
{
// Bind to the OU3 container, add a new User.
DirectoryEntry de = new DirectoryEntry("LDAP://CN=OU3,DC=Testing,DC=com");
}
catch (Exception Exception1)
{
// If a COMException is thrown, then the following code example can catch the text of the error.
// For more information about handling COM exceptions, see Handling Errors.
System.Runtime.InteropServices.COMException COMEx =
(System.Runtime.InteropServices.COMException)Exception1;
Console.WriteLine(COMEx.ErrorCode);
}
// try
//{
//DirectoryEntry de = new DirectoryEntry("LDAP://CN=OU3,DC=Testing,DC=com");
//}

}
//DirectoryEntry description = DotnetAD.SetProperty(Description,"description",TxtDescription);

this helps in creating a user account, now i am trying to use if condition so that if ou1 or ou2 or ou3 the user should be created in that respective OU.

so please let me know how and what should i change in that code so that the user should get created in there respective OU.

Array - Structure problem

Hi,

I have an array declared as a structure. The structure has n members.

I was wondering is this posible:

for i = 0 to array(index)
for each object in array(index)
do some work o the member of the stucture...
next
next

This particular code does not work. But you get the idea. My specific problem is that I have n array indexes (array items) and each item of that array has a structure of approxx. 9 members i need to iterate through each of those members and give them some value...

Thank You!

Something like this should work:

For Each MyStruct struct In MyArray
    ' Do something with struct
Next

Change MyStruct to whatever your structure type is.

Path to Installed Application

The description is pretty bad, so anything we say would mearly be guessing. A more accurate description would come from seeing the code defining your structure and the code defining your array.

How can I know the location of the Application where it is installed. I want to know where in the system 'Microsoft Office Document Imaging' has been installed. It can be installed in different locations in different machines. Is there any API or some kind of functions that can return back the path location to the installed application.

Any advice will help a lot.

Sekhar

Re: Path to Installed Application

Re: Path to Installed Application

31-Oct-07 6:05

Well, there is the "official way", using the MS Installer API functions, and there is the "quick'n'dirty" method.

The Offical method would be to use the MSI API to lookup the product code of the versions of Office you want to support, then look up the feature to see if it's installed, then get the feature information to get the installation path.

The quick'n'dirty method is to look in the Registry and find the "mspview.exe" key under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrnetVersion\App Paths\ key. If the "mspview.exe" key is there, you can look inside that for the "Path" value, which will give you the path to the Document Viewer executable.

Thanks Dave for the advice.
One more thing I wanted to know is that Is this the location(HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrnetVersion\App Paths) where we can get all the applications that has been loaded to the system ?
That is if I want to know any other application's Path then I have to search it here only ? And how can I access this path from the registry editor ? I used the GetSetting function, but it doesn't seem to work for that location.

i think you are looking for mnemonics for buttons on your form as you want that when user is typing in some textbox and press a key and automatically a button pressed for this purpose you should change the caption of button in following way

&Save for save button now from anywhere on a form if user press Alt + S the button Save is pressed and code for its click event is invoked Smile | :)

Data Binding

30-Oct-07 22:12

Which method is better for data binding (Design Time or Run Time).I have more than 1,00,000 records in the table which I want to show on the form.I this better to bind signle record at a time at run time or load the full table at once at design time.I knowat design time it will slow down the application as it will load the full table.

If I try at run time then how I can move to the next or previous record?

Any idea or sample code will be greatly appriciated.

Thanks In advance.

Neither. Which one you use depends on your requirements.

ejaz_pk wrote:

No, you don't. You have 1,000,000 records in a database, from which you retrieve an appropriate number of for display. Trying to show 1,000,000 records will do nothing but needly slow down the users experience. Holding that many records would also consume a enormous amount of memory.

The only time you'd ever retrieve that many records is if you're doing processing on each and every one of them. You never just retrieve that many "just because I might need them".

It will take a considerable amount of time to retrieve those records if the database is on the same machine as your application, and will take much, much longer if you have to get them over a network.

If you wanted to show that many records, depending on the control used, you would either use a Virtual mode of the control, like in a DataGridView, or implement some kind of paging operation.

That's what the BindingNavigator class is for.

Sorry about the misunderstanding.I don't want to show all the records at once.What I mean is that user can see one record at a time but he can navigate to next and previous record as well.Is there is any way to do this.

Thanks for ur reply.
