For Access, it's simply a matter of copying the .mdb file (via File.Copy). With SQL Server, it's a bit more complicated, you have lots of options, but the two simplest are:
1. Execute a "DUMP DATABASE" or "BACKUP DATABASE"
2. Use SQLDMO. There are lots of articles teaching how to use SQLDMO in C#, search on Google and you'll find it.
Yes, even I am blogging now!

Thanks Daniel for your help. It's good in case of .mdb but maybe i need sql solution but anyways your help is still for thanks... Thanks again..
Daniel do you have idea how can we share same database in different client mean if some there are some changing in one side db than how can we send changes to other client db. If you know i great but if you never know than it's not matter... Anyways thanks for you help

It depends what you mean by "change": if you want to keep data in sync, you could use SQL Server's replication (I believe that Access also support it, but I'm not sure).
If by "change", you mean changes in the database structure, I'd suggest you to use a product like "SQL Compare".

I am unsure as to if there is a class out there to do integration. I would suggest using Remiann sums and limits with ever increasingly small delta values. You will be able to get a close approximation for the integral. If anyone knows of calss to do differentiation and integration please comment on this. Thanks

Hi~
How do I write a form class extend to another form?
E.g
class Form1 : System.Windows.Forms.Form
class Form2 : Form1
However, I would like to use design to add controls to Form2
can I do that? Thanks

Hi,
yeah this is simple but required most of time.
suppose i had made one class and i want to use the properties and method of that class into another class of another form but is there any common thing (like common class or place) by in which i can create the instance of that class for once and i got excess of the properties to every class any time?
regards

Hi!
I have created a similar thread before and I was not able to find a possible solution. Here is the issue again.
I need someplace where I can filter all messages of the application (main form and all child forms). I have implemented message filters but somehow the child modal dialogs does not seem to have message filtered (there messages do not come into the filter).
|

MSDN link[^]
I'm sure someone has mentioned Application.AddMessageFilter Method. Its exactly what you need. The following example traps all left-button mouse activity:
#region IMessageFilter Members
public bool PreFilterMessage(ref Message m)
{
if (m.Msg >= 513 && m.Msg <= 515)
{
System.Diagnostics.Trace.WriteLine("Caught");
return true;
}
return false;
}
#endregion
If you have any problems post back.

I tired that but this message filter does not seem to work on child dialogs (froms).

I have an app written in C# (obviously). Here is my dilemma:
The form loads, instantiates a bunch of worker threads that execute one at a
time. When one finishes, it starts the next one in line. I have about 5
datagrids on 5 different tab pages in a tab control. What I'm using the
Threads for is pretty basic: get data from a database and fill a datagrid. I
use delegates throughout to allow the worker thread to call the
'FillDataGrid' method in the main thread (the form thread). I've had
problems before with threads not accessing other threads controls which is
why I use the delegates. But still it crashes with the following:
An unhandled exception of type 'System.ArgumentException' occurred in
system.windows.forms.dll
Additional information: Controls created on one thread cannot be parented to
a control on a different thread.
I decided to add another tab page (out of pure imagination) as the first tab
page in the control. voila! now everything loads properly (without changing
any code whatsoever). Problem is, I try to programmatically remove the
temporary page (with a generic "please wait while loading" message). It
removes the page fine, but on the next page in line, all the controls
dissappear. If I don't change or remove tab pages programmatically, all the
controls stay intact. I'm not sure what I am missing, and leaving the temp
page intact is just ugly. Anybody know what I'm missing?
If you put a time limit on this project, it won't ever get finished . . .

Personally I haven't worked much with this stuff, but from what I read I think that it might be a problem with how .net works with the ocx. Take a look at this article: http://support.microsoft.com/default.aspx?kbid=176468[^]

Are you talking about a ASP.NET app ??. For example in ASP.NET you are executing the application in the context of a web application and you can only show WebForms..
Try compiling as exe

Please clarify what you are try to accomplish.
When the user clicks where?? Abitrary point on the screen? Inside your form?
Note your application cannot pick up mouse clicks outside the form.
