I am using asp.net and the .net framework 2.0. I may be able to upgrade the servers to 3.5 if the solution is compelling enough. Here is the problem. I have two pieces of xml. I'll refer to piece number 1 as the template and piece number 2 as the actual. Here's a basic example:

I save my database in my application like this:
Public Sub save_mandant(Optional ByVal SName As String = "")
Dim set_temp As New DataSet
Dim set_tables As New DataSet
Dim ada_temp As New SqlDataAdapter("Select name from Sys.tables", SQLcon)
ada_temp.Fill(set_tables, "T")

View 1 RepliesSometimes 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 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 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?
I 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.
View 2 RepliesWhat are the differences between 32 and 64-bit .NET (4) applications?Often 32-bit applications have problems running on 64-bit machines and conversely. I know I can declare an integer as int32 and int64 (certainly int64 on 32-bit systems make problems). Are there other differences between programming an 32 OR 64-bit or a both 32 AND 64-bit compatible application?

View 3 RepliesWe have legacy character codes that we want to store as numbers in a new system. To increase readibility and general understanding in the code for devs making the migration, I want to do Enums like this..
[Code]...
With this setup, the code will be readable (imagine If Record.Status = Status.Open), and yet the values will be stored in the database as small numbers so it will be efficient. However... I am a VB.NET guy, but everybody wants to code in C#, so I need this sort of structure in C#.After Googling, I discovered the the general .NET equivalent of AscW is Convert.ToInt32("C"). When I try to use that statement in an enum, I get the compiler error "Constant Expression Required".
in order for me to get help on me and my programming partners vb6 rpg, I have to upgrade the project to the vb.net platform, and I am worried that the IDE interface that is used to program the vb side of the rpg is different, so I am wanting to ask any of you if there are any significant changes to the IDE or if it is relatively the same as it was in vb6... I am also hoping that someone here can also help me to see what is wrong with my load/save function... I now thought of something to try to see if that is the issue or not, but the code is still vb6 code, the only difference will be that the program will be upgraded to the .net platform, so if that changes anything in the code, then I am not aware of this as of yet, because I am still downloading the visual studios 2010 express iso right now... so I do not know for sure yet what will be changed.

View 1 RepliesToday I was playing around with Entity Framework and I've read that the generated IL for C# was different than VB.NET for the following code:
[code]...
As it seems the VB.NET version of this code will contact the database every time the code is executed while the C# version will retrieve the entities from the cache when the code is executed multiple times.Why would they make both languages behave in such a different manner?It was my misconception that both languages just differed in syntax and had almost exactly the same generated IL.Are there any more examples where both languages generated such different IL?

View 5 Repliesi'm using Enumerable.Except to check if a DataTable in memory is in sync with the table in database.
The background is: this DataTable and other frequently used tables are stored in the Cache of a WebApplication. But meanwhile i'm convinced that this is not a good approach because it's a source for nasty errors that are difficult to reproduce/debug.
Therefore i've created a function that checks if database and memory are in sync, otherwise an error-log will be created. This works perfectly. If there is a row in memory that is not in database, this row will be shown below "Difference in database", the same applies in reverse. But if rows exist in both datasources(the PK idRMA) and some values differ, the log will contain this row in two versions(below "Difference in database" and "Difference in database"). It is not easy to see the differences on the first sight.
Q: Is it possible to select only the properties that caused Except to think that first sequence is not in second?
This is the the complete function(the first lines are relevant):
Public Shared Sub CheckRmaMemoryInSyncWithDB()
Dim inSyncText As String
Dim color As Drawing.Color
