Your program can't be on top of everything, unless it is running as a screensaver. Other applications will fight for the right of being the topmost. The login-screen and the desktop are "desktop" objects, capable of showing applications. You'd need to create one (example here[^]) and then run your application in that new desktop. There's bound to be an article on CodeProject that shows "desktop switching", which would be a good place to start* No, not easy if you're new to .NET. --edit *) Found it; Desktop Switching[^]. Contains a desktop-class that hides the complicated stuff. Bastard Programmer from Hell :suss: If you can't read my code, try converting it here[^][](X-Clacks-Overhead: GNU Terry Pratchett)

Thanks, i solved the issue, my error was that i was trying to serialize an object of type DataGridViewRowCollection which is not marked as a Serializable object, i made my custom class which marked as Serializable, i had stored all the data in the DataGridViewRowCollection in that class, now everything is OK thanks again,

From the code, I understand that you are trying to create table in access from the dataset but your approach is not acceptable for ADOX. In a similar task, I have tried to export my dataset to an mdb database and I had to construct SQL commands from the dataset to create and insert data. I think this one can give you a starting point. Here is my create table method: /// /// Constructs the required SQL Query to create the tables in mdb database and then executes the query. /// private void CreateTables() { string sqlCommand = "CREATE TABLE "; foreach (DataTable dTable in currentDataSet.Tables) { string sqlCreate = sqlCommand + dTable.TableName + "("; int cnt = 0; foreach (DataColumn dColumn in dTable.Columns) { string sqlCreateCommand = sqlCreate + dColumn.ColumnName; if (cnt != dTable.Columns.Count - 1) { cnt++; sqlCreateCommand += GetDataType(dColumn) + ", "; } if (dTable.Columns.IndexOf(dColumn) == dTable.Columns.Count - 1) { cnt++; sqlCreateCommand += GetDataType(dColumn) + ");"; } sqlCreate = sqlCreateCommand; } OleDbCommand dbCommand = new OleDbCommand(sqlCreate, (OleDbConnection)dsConnection.CurrentDbConnection); dbCommand.ExecuteNonQuery(); } Always keep the Murphy Rules in mind!

Few links I quickly found: - Web Services Description Language Tool (Wsdl.exe)[^] - Creating an XML Web Service Proxy[^] - Reverse Engineering Through WSDL.EXE[^] - Invoking a Web Service Without Web Reference[^] I hope these would help you. The idea is that the services you call contain the same web methods (at least the ones you use). So when you add a new service or want to change the service, you actually use the same proxy and change the url. The need to optimize rises from a bad design. My articles[^]

i dont understand that using a desktop application

I use the [System.Timers.Timer] object in my Windows Services: - System.Timers.Timer t; void OnStart(string[] args) { t = new System.Timers.Timer(); t.Interval = 1000; t.Elapsed += new System.Timers.ElapsedEventHandler(t_Elapsed); t.Enabled = true; } void t_Elapsed(object sender, System.Timers.ElapsedEventArgs e) { ... }

i had sent you the script through mail, yes the script lie on the C:\ partition

sure it is not a malicious software, let me explain, we are developing web application that being used inside our company network, and we need to make an application that keep tracking of the user event on the page controls, this will help us when there is an error or exception, we want our application to send us the scenario that makes the errors or exceptions, in order to analyze it and make a knowledge base for our support to our users

here it is void CChildView::OnPaint() { CPaintDC dc(this); glClear(GL_COLOR_BUFFER_BIT); RenderScene(); //calling my OpenGL drawing function glFlush(); SwapBuffers(m_pDC->GetSafeHdc()); }

U can Use this OnInit.... CRect Rect; GetParentFrame()->GetWindowRect(&Rect); GetParentFrame()->SetWindowPos( NULL,0,0,900 ,200 ,SWP_NOMOVE | SWP_NOZORDER); SIZE size; size.cx=Rect.Width(); size.cy=Rect.Height()/2; SetScaleToFitSize(size); "The Ultimate Limit Is Only Your Imagination."

Whats wrong with overriding OnMouseXXX events? There is a nice mechanism called Hooks (Hooks Chain). You can use it to catch mouse, keyboard and probably a few more things. http://msdn2.microsoft.com/en-us/library/ms644959.aspx[^] Good luck Sincerely yours Y.R.
