I want to create a form almost exactly like the database properties page that appears in SQL Server Management Studio when the properties of a SQL CE database is selected. Basically, the form has page options that show general properties in a propertygrid, a shrink and repair page option, and an option to set the password. Does Microsoft have some code posted on how they show the properties page of a sql ce database?

I've created a class and put its objects into an Arraylist.
Here is the class:

View 2 RepliesQuickest way to enumerate the alphabet in C#
Because I need to get all the characters of the alphabet OF AN ARBITRARY (variable) LANGUAGE, and that in the correct ordering sequence.
How can I do that without knowing the alphabet of every possible culture/language? System.Gobalization.Cultureinfo for example has information on date format, and a sorting method, and codepage info. But not info on the alphabet itselfs. Forthermore 'A' to 'Z' ordering iterating won't do, because German for example has characters such as ÄÖÜ, which are after 'Z' in the codepage numbering, but follow after aou when sorting.
Can I somehow use the codepages to get all the characters, and sort them somehow ? By 'all the characters' I mean all letters, including numbers, but not punctuation marks. And possibly only upper XOR lowercase.

faster way to enumerate through a directory and sub-folders to gather all the files in the enumeration? This is what I have right now:

View 4 RepliesIn a case where you would like to reset an array of boolean values what is faster, rediming the array or enumerating and resetting the values? I have run some tests and they seem to suggest that a redim is a lot faster but I am not convinced that it isnt a result of how I'm running the tests.
My tests seem to suggest that redim is nearly twice as fast.So could anyone care to comment on which is faster and why? Also would you expect the same result across different languages?

I need to have a property that is a nullable date as the datestamp is used for when a process is completed. If there is no date this is a way to determine if the process has occurred. I have created a Nuallable DateTime property (DateTime?) However when I try to assign a value from my database entity (when debugged has a date value) I am not thrown an exception however my property still reads a null value after assignment. How can I get a DateTime? type to accept a DateTime value?
I thought this would do the trick
_object.DateStamp (type = DateTime?) =
_entity.DateStamp (Type = DateTime?, Value = DateTime) o
Or for more understandable syntax
Ctype(object.DateStamp, DateTime?) = Ctype(entity.DateStamp, DateTime?)
Strange thing is I can assign the properties value like this.
Ctype(object.DateStamp, DateTime?) = Now

where I have to try organise a number of databases. Some of these I am sure are duplicate databases.I was wondering if anyone knew if there was a way to interigate the database objects so as to make a comparison between databases (see if they are in fact duplicates.)I would (ideally) like to get a list of all database objects - such as queries, forms, tables,modules etc.. Then look at either the "date modified" or "date created" property so as to see which is the most up to date as well as somparing the contents of the database.I have played with Delphi and dbGo to try see if I can get the info required - but cant seem to get all the properties I need.Here is an example of what I have tried using the "openschema" method such as...
Con2.openschema (siTables, EmptyParam, EmptyParam,DS1);
But afaik - this just returns a list of the objects (in this case tables.)I also tried..
Con2.GetProcedureNames(Listbox1.Items);
But again - theis just returns a list of the database items. I know I have used Delphi here.. But Im sure the principle is the same for VB ?
i have several classes / objects from it in a program that hold data like clsAddress with properties id, city, zipcode, name, and clsMyData that contain id, datafield1, datafield2, datafield3 and many more (just examples) I want to have methods in the objects to load the object from and save the object into a database, like me.loadFromDb and me.SaveToDb Of course i can do creating db tables like tAdress, tMyData, ... and in the methods do select / insert statements like "insert into adresses (city, zipcode, name) values(me.city, me.zipcode, me.name) etc. BUT - what i dont like is a) i need to build this loadfromDB / saveToDB Methods for every class separately and b) whenever i alter a class, i must alter the DB structure and the methods.

I am trying to enumerate the
HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionUninstall
registry key and check the displayname & displayversion registry value for all the sub keys under the uninstall key then compare the displayname & displayversion value with a if statement.
For example if one of the the displayname = "Adobe Flash Player 10 ActiveX" & displayversion = "10.1.82.76" then textbox.text = "Your adobe flash is up to date"
This is the code I been using to check a specific registry value to see if quicktime 7.67.75.0 is installed i figured it would be best to enumerate the subkeys and check the displayname & displayversion because im checking like 6 programs to see if the version is current.
Dim quicktime As String
quicktime = My.Computer.Registry.GetValue _
("HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionUninstall{EB900AF8-CC61-4E15-871B-98D1EA3E8025}", "DisplayVersion", Nothing)

I have used NeServerEnum initially to allocate all of the available servers but have yet to get the NetFileEnum to work correctly. I have used 'Nothing' for the server name and it won't recognize the process on the local machine. If I try to select a server it returns '1113'. This code from what I have found means either 'the file is already open' which means little to me or ERROR_NO_UNICODE_TRANSLATION, just from what research I have collected on the number. The following is my code.

Using Visual Studio .NET 2008 or 2005, is there a way to automatically generate properties for each column in an SQL Server database table?

View 6 RepliesI have a class that represents the table of a db-row. Its properties are the columns of the table. I add a new row to the table with the following code:
Public Sub AddRow(oTestRow As TestRow)
Dim sql As String
With oTestRow
[Code]....
That is just an example, but my classes have around 30-40 properties and this brings a very large and complex sql string. Creating, editing or maintaining these sql strings for many classes could generate errors. I am wondering if any compact way or method exists in order to add the whole object's istance (the properties of course) to the table "TestTable" without writing such a large sql string. I created the TestRow in the way that its properties are exactly the columns of the table "TestTable" (with the same name). But I did not found in the ADO.NET anything that could be used.
