In addition to Dave's answer, it's usually not worth the effort. Unless you use the highlight-color as defined in the system-colors, your blue would default to red on my desktop 
If it's merely to get consistency then do consider the fact that you are adding code that might throw exceptions/have bugs, while the only advantage is color-consistency (one that is still a non-default, and hence, unexpected)
If you are letting the user make a selection, then you could consider using checkboxes to indicate the selection.

Thank you gentlemen. I've decided to leave the default behavior alone.

Hello !
I'm using Vb.net 2013 , Entity Framework , SQL Server 2008R2 and SMO.
I want to disconnect from database and set offline.
I try this code using SMO:
conn = New ServerConnection()
conn.ServerInstance = serverName
srv = New Server(conn)
Dim db As Database
db = srv.Databases(databaseName)
db.setoffline
But the problem is that the application hang on the last line and doesn't respond.
Is there anything that I should do with entity framework before set the database offline ?
Thank you !

You can't use EF to offline a database. You have to use the normal SqlCommand and SqlConnection objects to execute the query yourself.

Hi Everyone,

If Not Data.Recordset.EOF Then
Data.UpdateControls
If OLEWord.OLEType = vbOLEEmbedded Then
Set mWordDoc = OLEWord.object

OLEWord.DoVerb vbOLEOpen
End If
End If
End If
Data.Recordset.Close

Check your connection-string; it's not related to Word, it's related to the query.

Thanks for your reply.
My connection string like below
"ODBC;DSN=SampleDSN;;UID=SampleId;PWD=sample;"
The error says default driver missing where can we set default driver for specified ODBC connection

I am trying to mirror a VB frame to RightToLeft direction. I succeeded to mirror the frame, but all the text of frame components(Labels and text box) are mirrored too.
Is there any way to prevent the components to be mirror?
Const WS_EX_LAYOUTRTL = &H400000
Const WS_EX_NOINHERITLAYOUT = &H100000
Protected Overrides ReadOnly Property CreateParams() As System.Windows.Forms.CreateParams
Get
Dim CP As System.Windows.Forms.CreateParams = MyBase.CreateParams
If Not MyBase.DesignMode() Then
CP.ExStyle = CP.ExStyle Or WS_EX_LAYOUTRTL
End If
Return CP
End Get
End Property
When I tried to add "OR WS_EX_NOINHERITLAYOUT " the frame didn't mirror at all.

Error Message? OutOfMemory?
By the way, do you think it is a good UI design to show 3000 items on a single form?
|
|
|
|
|
Yes, it said out of memory
Actually, it will have 700 rows and each row has 4 columns.
Each cell will contain one UserControl
So, I need to have maximum 2800 controls to be loaded
However, I can unload some empty cell to make it lesser

What do you mean Usercontrol?.
I have populated a access Database to a Datagridview.|

It's not only text, it's a control that contain a picture box, 4 labels with nicely format.

This tells you that something fatal happened, and your application has not been written to trap and report the error properly. Exceptions should be caught in Try ... Catch blocks, and information reported to the user about what is happening, and where. If you don't know where the error occurred then you will need to run your application in the debugger to find out. Once you have done that you should be able to discover why the error occurred. See http://msdn.microsoft.com/en-GB/library/fk6t46tz.aspx[^] for more information.

Everything is OK before I Publish.After publish I Think Application can't connect to DB because it is not include in the setup file or .....that i don't know.

Well I am afraid there is no way anyone here would know. It is no good trying to guess what is wrong. You need to do some serious debugging of your application to find the problem and fix it properly so it does not happen again, or if it does, that it produces some useful information about the exception.

Hopefully, you didn't put the Access database in the same folder as your application under Program Files. If you did, the Program Files folder, and everything under it, is READ ONLY to normal users. They won't be able to open the Access database because of that.
You have to put the Access database in a folder more appropriate, such as under CommonApplicationData[^] somewhere.
|
|
|
|

Yes.
After I Publish.
1. I run Settup.I Install my application to the folder.
2. I copy access file to this folder at the step 1 then application run.
Question 1. How to manual the folder at the step 1?
Question 2. How the settup include the DB file?
|
|
|
|

I have no idea what you're talking about. "the folder" and "this folder" do not tell me EXACTLY which folder you're talking about.
Nor do I have any idea what you're using to package up your application into a Setup.
|
|
|
|
|
I Mean The Folder after I Install the application.

How do you create your setup project / which tools do you use for that?
Where do you define the connection string to the database?
Do you adjust that when the user executes the setup?
|
|
|
|
|
This is My First Project that connect to DB so I am not sure, just use the publish tool in Visual Studio 2010.
Please leave your Skype ID so I can ask you more detail.
Thanks.
