Question: How do I programmatically determine which provider to use (Microsoft.Jet.OLEDB.4.0 vs Microsoft.ACE.OLEDB.12.0) when my app runs as a 32-bit process on a machine with Office x64 installed?
I'm developing a VB.net WinForms app in VS 2010 and targeting both x86 and x64.The app processes data from xls, xlsx, mdb and accdb files using System.Data.OleDb:Dim oConn As OleDbConnection = New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=...")
The x64 version of the program works as expected. The x86 version works as expected on a system with Office x86.When I run the x86 version on a machine with Office 2010 x64, I get the following exception when trying to open a connection:
The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.I believe this is because I'm running Office 2010 x64 so the x86 data access components are not installed.I can get it to work for Office 2003 files (*.mdb and *.xls) by changing the provider to Microsoft.Jet.OLEDB.4.0.
How do I figure out which provider to use when running as a 32-bit process on a machine with Office x64 installed?Ideally, I'd like a function:If ProviderIsAvailableFor("Microsoft.ACE.OLEDB.12.0") Then
Else If ProviderIsAvailableFor("Microsoft.JET.OLEDB.4.0") Then
I have been trying my hand at this for some days now and just cant get anything to work.

I am not sure if it is possible, but I would like to be able to provide a custom "SelectedHighlight" color when an item is selcted in both a treeview and a listview (Better yet, any) control.
While I am a fan of sticking with established convention in most cases, There are times and places when I would like to do this.
A. Is it possible to do this? And by possible, I am looking to Override the Default system SystemHighlight at runtime, for only a particular control. I am NOT looking to change global system settings (at least, outside of any time when the particular control has the focus.
B. I haver tried a few searches, and I will contiinue (Try searching for any combination of "System", Color", "Selection", and "Highlight" and see what comes back!).

im using data bound item with my combobox and this error pop up.
Parameter @UserType has no default value.
when i set the value,it stated that
"The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. Change the data in the field or fields that contain duplicate data, remove the index, or redefine the index to permit duplicate entries and try again."
should i edit my usertype column in my database or there have another solution?
I am working on a very simple application in Visual Basic 2008 Express.
The program has a Listview where I display the "DisplayName" field, the user clicks on a name and this should fill 3 text boxes. The code is:
strSQL = "SELECT FName, LName, DisplayName FROM tStaff WHERE DisplayName=@DisplayName;"
Dim conn As New OleDbConnection(strConnString)
[Code]....
This produces the error "Parameter @DisplayName" has no defaul value"
The value of the variable "strDisplayName" is correctly captured.
I want to include an optional parameter in a function statement that is of the type Unit. For example:
Public Shared Function NewTable(Optional ByVal TableWidth As Unit) As Table
Optional parameters require a default value, but I cannot figure out how to set a default value for a Unit type.
We have a legacy component that has been converted from VB6 to VB.Net.The VB component was called from an ASPX page using Request("param") to pass optional parameters to function calls. That means the value is null/nothing if the parameter is not present.The parameters were then added to an ADODB call of a store procedure using Parameters.Append.When used from VB6 missing, Request("param") values were coerced into empty strings when passed to the VB6 component. This meant that the ADODB call was satisfied (for required parameters).When the code was ported to VB.Net, the null Request("param") values are now passed as null values (VB nothing?) and Parameters.Append skips adding the value if it is nothing. This caused the stored procedure calls to break as a required param was missing.
If we change the component's function parameters to be optional and have paramname as string = "" defaults, will a null/nothing value be converted to an empty string, or is null/nothing treated differently to a parameter being simply missing?
I have a problem during defining a Sub routine in VB.Net. I am defining a sub routine which is as under
Private Sub ActivateControls(rdbutton as RadioButton, Optional txt as Textbox, Optional txt2 as Textbox)
End sub
When I call this sub routine It gives me the Error that Each Optional Parameter must specify a default value. So, Here I can't understand that what can be the default value of a textbox. What default value I can use here to remove this error.
I think this is a pretty basic question, but I just want to clarify. If I have a variable with a null value, and pass it as a parameter that is optional, will the parameter get the null value, or the default value?
