I'm using the below to restore a database in VB.NET.This works but causes the interface to lockup if the user clicks anything.Also, I cannot get the progress label to update incrementally, it's blank until the backup is complete then displays 100%.[code]
View 1 RepliesI have written a windows form which allows a user to backup the database to medium of their choice and this works fine. I am now trying to use a very similar windows form to restore the database from previous backups.The problem I am having is the restore fails because the database is in use by this session. Googling this fault there appears to be several different solutions including using the master database, using tempdb or setting the database to single user but I cant find out how to do any of them with regarding what code to use.The option of changing to single user mode seemed the easiest but what coding do I have to use.[code]

View 1 RepliesI am trying to restore SQL server DB, replacing the existing one but donot know how to do it.My purpose is to restore the backup file selected by user, no matter if file with this name is already attached to the server or not. If it is there, it should be replaced by the new one.
View 1 RepliesI have created an ASP.NET class derived from the standard WebControls.TextBox, with the intention of adding extra properties that will persist between post-backs. However, I cannot figure how to get the values in these properties to persist. I have tried setting the value of the properties into the controls ViewState as part of the PreRender handler, but the value is then not accessible in the Init handler on the post-back, because the ViewState has not yet been setup.
I could look for the ViewState value in the Load handler of the control, but if the page/usercontrol that is using the control asks for the properties value during its Load handler, the control hasn't yet reached it's Load handler, and it therefore not there.
[Code]...
In the end, the way I managed to get it to work was to use a <asp:PlaceHolder> control within the repeater, create an instance of my control within the ItemDataBound handler of the repeater, and then add the control to the <asp:PlaceHolder>... all done within the Init section (which fortunately I'm able to do).
As Andrew found out in this previous question you can end up in a chicken/egg situation, where you need to create the controls in the Init, but you won't know what controls you need until the Load.
I need to create an application that will restore a user's mapped drives from a database. To do this, I need to create a script that will automatically back up the user's mapped drives on logon.
What would be the best way to go about doing this?
Sometimes I select a value in my Combobox by hand, and sometimes the value to show is chosen elsewhere in my program logic. I want to carry out a certain action only when I have chosen a value by hand, and not when the value is changed by the program. For this reason I use the DropDownClosed event (and not, for example, SelectedValueChanged or SelectedIndexChanged). This works fine, but if I set AutoCompleteMode of my Combobox to Suggest, selecting a value from the suggested list doesn't fire the DropDownClosed event (perhaps logical, as the actual drop down list doesn't actually open).
View 2 RepliesI just downloaded VS 2010 beta to try my hand at re-learning (from scratch it seems) some of this to do a somewhat basic app. At the moment I have a tree view and it contains/will contain paired parent and child data. There's a Title (the parent) and a URL (child) and that's it with regard to depth. There will be potentially lots of these pairs. That said there may be some options associated with those pairs that would also need to be stored later. I'm thinking the best way to deal with this is to store the data in XML format but, of course, I've never really done much with XML though I can physically read it. Could someone point me or provide a piece of code that saves and restores a tree? [Code]
View 1 RepliesI have an MDI application that uses the menustrip control. When the MDI Child window is maximized, there is no way to restore its size. There's a restore on the MDI parent but that restores the entire application. However, when I use the Main menu, there are two sets of Maximize/Minimize controls, one for the MDI parent and one for the MDI Child. The Mainmenu control adds a band that is used to display the Maximize/Minimize controls but the band the menustrip creates is not used to do the same.
View 3 Repliesrecommend the cleanest way to save / restore a winform's location and state? For some time now I've been using a method similiar to what I posted below (based on the CodeProject: [URL]..The problem with this method is that when the form loads, it is drawn in an initial location, then moved / maximized afterwards. The effect creates somewhat of an eye sore watching the window draw, then quickly update... but in Vista it is a lot more obvious.
What I would like to do is restore a form to it's previously saved location / state invisible to the user, then show it once it's where it needs to be. Or, just know of the ideal way this is supposed to be done - specifically in Vista.

I have a DGV where I'm setting the backcolor of certain cells to light gray. But I need to be able to restore the backcolor to what it was before I changed it to gray. I could just set it to transparent, but the problem with that is that I use an alternating row color of alice blue for the DGV & setting a cell in a blue row to transparent makes it white. So, in summary, I need to be able to restore white rows to white & blue rows to blue. Any ideas? I thought about checking the backcolor of another column in the row & then using that to reset the cell, but that seems kind of a hack.
View 1 RepliesI have a DataGridView in one of my form which at a certain point I resize an change it's position. I would like to be able to restore it to the designer's default position at runtime. I know I could save it before changing and then restoring it later, but I feel like there surely is a way in .NET to just restore a control position to it's default.

I recently upgraded the MS SQL Server installed on my personal computer from 2005 Express to 2008 Express. Problem is when I try to add an SQL database file to a project using VS 2005 I get an error message saying that the version of my database server is not supported, I must have SQL Server 2005 Beta 2 or later installed. I didn't do it yet but I'm pretty sure that when I open the other projects that I included a database file to it, I'm going to get the same error.
My question is it possible to have two SQL Servers installed on my machine? If so, is it a good idea to have two DB servers in the same machine?
I want to move my programs and the database to another computer and hard-disks. It looks to me as though I nearly have to re-create the controls and rewrite some of the code to make it so the programs still work after the move. At least with ODBC all I would change was the DSN definitions external to the programs. Is there an easy way to move or rename a database without loads of work?
View 3 RepliesThis program is very difficult for me, but I must get threw it or I cannot finish... What I am doing is making a Database of foreign Languages with the spelling of the words and the pronounciation inside the database... The USER enters a paragraph of words into the translator textbox and pushed translate. The program has a DATABANK of words with the phonetic spellings and matches the word, then translates to phonetics. The problem is that new words keep appearing inside the language. So I incorporated a Database of 2 fields

View 1 RepliesI'm trying to use LINQ to SQL in Visual Basic 2010 Express.
It allows me to create the .dbml file, but in order to drag items from the Database Explorer window to the design surface, I first have to get my database listed in the Database Explorer!(this is a remote SQL Server database - not a local .mdf)
I already have a good, working connection string to the remote SQL Server database, but that doesn't help me when I'm trying to generate the DBML at design time.
Can anyone tell me how to get my remote SQL Server database identified in the Database Explorere window? When I try the "Add Connection", I am limited to Access, SQL Server Compact, or SQL Server Database File. If I try to enter the IP address & port of my DB Host I get a 'database file does not exist' message. Doesn't seem to want to let me point to a remote DB server...

Friends I have Developed my Data base Project on vb6, using adodc and datagrid using ms access database file, it was working nice in vb6, I also put Search box there and used adodc1.recordsource="select * from table" sql query.
later i needed to convert it in vb.net I converted it, every thing is working fine, but one problem appears, an adodc's Recordsource query for searching records is not working, it only works if there is data in dataset (Datagrid),suppose once i pressed search button to search record and if no record found then dataset / datagrid becomes empty, now i wanted to search an other record with other name, but this time it does not work and following error appears Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record.

I am sitting with a situation that I have to combined (3 years) for 26 site of 29000 database files where there is 1 table in each data base called RECDATA, I need to combined all that data Into one database file called RECDATA.
For example there is a database called DB1 with a REDATA table inside it, and then DB2 with a RECDATA table inside it, DB3 with a RECDATA table inside it est. So I need to put all the Recdata into 1 Database file, or to copy all the RECDATA from all the database files to 1 RECDATA they all have the same columns All I need is to get all that data into 1 RECDATA table.
The program where this database comes from is a voicerecording system creating a new database every day. There is 1 database just for indexing (to view the recordings) and then the daily database is where the recording lies in, that Colum is called RECFILE. I will give you a example of the 2 database.
I have a report made in Crystal Reports XI. The report is generated and exported to PDF in visual basic script using COM interface. Generally everything is running smoothly, but in one case generation breaks with error: Failed to retrieve data from the database. Details: [Database Vendor Code 9421]
Database used is MSSQL 2005 connected over ODBC to CR XI. When I am opening report with exactly the same parameters in Designer, everything works fine.It looks like it is data related, but it is hard to trace since the whole report is pretty sophisticated. Anyway I spent half a day on crawling over Dr. Google and it seems that he has no clue what might be an issue.
I have VS 2005 installed in my sytem fyi.We have two databases, say source database and destination database. The databases is in Oracle. Now we need to pull data from Source database, manipulate it and push it into the destination database on daily basis.We are planning to use VB .Net for this and would like to know if this is feasible. Using windows forms through VB .NET, is it possible to create a exe and schedule the exe on nightly basis to pull the data from source to destination.how to do this as for manipulation of data, there is no intermediate database for us?
