How To Synchronize Combobox With Textfield
Sep 27, 2009[Code]....
synchronizing a combobox with a textfield. I have a form with a textfield and a combobox. The combobox is populated with the department name from the database when the form loads. I would like the textbox to display the corresponding department number when the user selects a department name from the combobox. I have tried using the SelectedIndexChanged event of the combobox but I can't seem to code it to work. This is the code I'm trying to use but it is displaying "DEPARTMENT" in the textbox. Department Code is the primary key of the table.
strSQL = "SELECT * FROM DEPARTMENT"
Dim da = New OracleDataAdapter(strSQL, cn)
da.Fill(dSet, "DEPARTMENT" )

View 2 RepliesUnable To Synchronize The My.Settings?
Sep 29, 2009With my program I wanted to change the fixed connection string to a User entered one. So in the application settings I added DBConnectionString as a user define String. If the string if empty, it shows the window where one can add the server, database and user name / password. If you press the OK button, it saves the settings:
Private Sub LDBOKBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LDBOKBtn.Click
' ----- Server name is required.
If (Trim(LDBServer.Text) = "") Then
MsgBox("The Server or Host name is required.", _
[code]....
The problem is that when you press the same button to show the System Settings again, the ConnectionString is empty again. So nothing was saved.
VS 2010 Synchronize Files?
Jul 5, 2011I have written a stupid backup utility that copies new or modified files. That's fantastic until I come across files that are 11 GB in size that have been modified. I have a feeling I can compare the file to be backed up and the file that will be over-written (old version of file) and "synchronize" the file instead of copying the entire 11 GB.

View 5 Replies.net - Using SyncLock To Synchronize Access To List(of T)?
Nov 16, 2010I have a class that contains a List(of T) used in a multithreaded application. I have three methods Get, Add and Remove where these access and modify the List(of T). I was using SyncLock to lock m_List any time I queried it for the desired object as well as when I added or removed objects. However I'm curious as to if there is a performance gain by simply locking m_List when I add an object or remove an object as opposed to when I'm searching for a desired object?

Synchronize Application Objects With DataSet
Mar 14, 2012I sometimes come across patterns or common practices that I do not agree with. I have a clear opinon of what is considered "good design", which is mainly based on my understanding of abstraction and creating layers.IMO, the core of an application is it's object model. It's a hierarchic model where one object references other objects or lists of them. That's a memory-internal model. For example, a house object references a list of rooms referencing lists of furniture.An object is identified by it's reference. There are no IDs or PKs in that layer.Saving/Loading data is an additional feature. Sure, no application will do without, but it's based on top of the core of the application. I could write an application that works very well without loading/saving, and for version 2 I will think about whether to save data to a database or an XML file. Merely this fact proves that a database layer is not the lowest. I've never agreed with that three-tier model - even if you call me unteachable.
In addition to all application objects, there are Datasets - and that's my problem now. They can be considered as a copy of what is already present in the application's object model. Its from a different, table-oriented view. As both structures exist in parallel, there's the need to synchronize the DataSet with the (rest of the) application's objects.That's the task that I am always struggling with, and I ask how you handle it. I know this is a major design question but, fortunatelly, I could quite get around this problem so far.The only solution I can imagine is maintaining additional relation lists. For example, whenever the property of a room object changes, that change must be reflected in the associated DataRow in the DataSet. For this purpose, I need a look-up table that tells me the PK of the given room in the database. It requires a lot of additional efforst to do all the synchronization.Again, the house or room object itself does not have a PK and it won't get one because on that layer, it doesn't even know that a database exists.

View 7 RepliesHow To Synchronize Near Realtime Reads From A Sql Server Table
Sep 12, 2011We have a reporting app thats needs to update it's charts as the data gets written to it's corresponding table. (the report is based off just one table). Currently we just keep the last read sessionid + rowid (unique combo) in memory and a polling timer just does a select where rowid > what we have in memory (to get the latest rows added). Timer runs every second or so and the fast sql reader does it's job well. So far so good. However I feel this is not optimal because sometimes there are pauses in the data writes due to the process by design. (user clicking the pause button on the system that writes data). Meanwhile our timer keeps hitting the db and does not get any new rows. No errors or anything. How is this situation normally handled. The app that writes the data is separate from the reporting app. The 2 apps run on different machines. Bottomline : How to get data into a c# app as and when it is written into a sql server table without polling unnecessarily.
