Switching between custom and default windows shells, in WinXPe [modified]

Hello,

I am looking for a solution wherein, in a system with Windows XP Embedded, a user boots into my custom application shell, but can switch to the Windows explorer shell, or vice versa, if he so pleases, without having to reboot or log off.

Or can this be possibly better applied by having a theme sort of implementation, much like that in XP desktop, where user have the ability to load different themes? If so, how should I go about it?

Thanx in advance...

Transfer data faster

hi guys

Im transfering data from sql server 2005 to
comapact framework database (*.sdf)
My way to do so is :
Export the table into an XML file (using DataTable)

dt.WriteXml(FName, System.Data.XmlWriteMode.IgnoreSchema)

And on the mobile device I load the XML and save the Dataset

dt.ReadXml(FileName)
da.Update(DataSet11)

Everything is working only my table contains about 1500 records (20 fields)
and it takes about 6 minutes to load and save.

Is there any way or Method to do this any faster ?

Thanks in Advance
Dan.

Rather ironically for something called 'SQL Server CE', the SQL language is the worst, slowest way to do anything. If you're using .NET Compact Framework 2.0, the solution for loading data that's the fastest to execute while still being pretty readable and maintainable is to use the SqlCeResultSet class.

To do this, create a SqlCeCommand, passing just the name of the table to modify in the query text parameter. Then set the command type to CommandType.TableDirect. Associate it with an open SqlCeConnection and call ExecuteResultSet, using the ResultSetOptions.Updatable option. Then, on the SqlCeResultSet, call CreateRecord to get a new record, set the record's properties, then call Insert to insert it into the table.

See SQL Server Compact Edition Insert Performance[^] for details on just how big a difference this makes.

Equally, a direct table access operation is far, far faster than SELECTing from that table - not just time to first row being returned, but even the time to access each subsequent row. To access the results in a particular order, you can use the IndexName property to use a named index on the table, and you can use the SetRange method to restrict the set of results that are returned.

Yes. Use SharpZipLib (also known as NZipLib) CF library to compress the files before sending them over. You can get it here:

Hello,

I am writing a smartphone application in visual C++ using WTL. And I want to change background color in progress bar. I am using following code to do this functionality.

CProgressBarCtrl m_ProgressBarCtrl;

m_ProgressBarCtrl.SetBkColor(RGB(0,255,0));

When I compile this code, I am getting following error:-

***********************************************************************************************
error C2039: 'SetBkColor' : is not a member of 'WTL::CProgressBarCtrlT<tbase>'
with
[
TBase=ATL::CWindow
]

***********************************************************************************************

I don't know what else to do to change background color of progress bar.

Can anyone help me with this?

I'd really appreciate it.

Thanks,

Muthiah.

Hi Muthiah,

The WinCE Progress bar control doesn't support the underlying PBM_SETBKCOLOR message, so WTL::CProgressBarCtrlT<TBase>::SetBkColor() is not present on WinCE platforms.

Subclass your progress bar and handle WM_ERASEBKGND at your liking.

RAS connection using GSM - GPRS Modem [modified]

20-Sep-07 10:57

How do I programmatically set the Extra Initialization string on the modem when making a RAS connection through a GSM – GPRS modem device to get TCP/IP connectivity through the ISP provider to the internet??

Here’s the Extra Initialization string needed on the modem for RAS: +CGDCONT=1,"IP,"IPS.CINGULAR"

Here’s my targeted device environment:
OS: Windows CE 5.0 (using .Net Compact Framework 2.0)

Here’s the sample code that I’m calling to connect to a RAS phonebook entry profile.

namespace TestDevices
{
class RasWrapperII
{
[DllImport("coredll.dll")]
public static extern uint RasDial(IntPtr dialExtensions,
IntPtr phoneBookPath,
IntPtr rasDialParam,
uint NotifierType,
IntPtr notifier,
ref IntPtr pRasConn);

[DllImport("coredll.dll")]
public static extern uint RasHangUp(IntPtr pRasConn);

///

/// EntryName ,UserName,Password - same as in RASDIALPARAMS structure (see MSDN)
///

/// <param name="EntryName" />
/// <param name="UserName" />
/// <param name="Password" />
/// <param name="RasConn" />
/// <returns>
unsafe public static uint myRasDial(string EntryName, string UserName, string Password, out IntPtr RasConn)
{
uint r = 0;
RasConn = IntPtr.Zero;
byte[] bRASDIALPARAMS = new byte[1464];
fixed (byte* pAddr = bRASDIALPARAMS)
{
byte* pCurrent = pAddr;
Marshal.WriteInt32((IntPtr)pCurrent, bRASDIALPARAMS.Length);
pCurrent += 4;
foreach (byte b in Encoding.Unicode.GetBytes(EntryName))
{
Marshal.WriteByte((IntPtr)pCurrent, b);
pCurrent++;
}
pCurrent = pAddr + 0x192; //0x192 - offset for RASDIALPARAMS.UserName
foreach (byte b in Encoding.Unicode.GetBytes(UserName))
{
Marshal.WriteByte((IntPtr)pCurrent, b);
pCurrent++;
}
pCurrent = pAddr + 0x394; //0x394 - offset for RASDIALPARAMS.Password
foreach (byte b in Encoding.Unicode.GetBytes(Password))
{
Marshal.WriteByte((IntPtr)pCurrent, b);
pCurrent++;
}
r = RasDial(IntPtr.Zero, IntPtr.Zero, (IntPtr)pAddr, 0, IntPtr.Zero, ref RasConn);
}
return r;
}
}
}

The Call Code:

IntPtr conn; // connection handle
uint rc = RasWrapperII.myRasDial(this.txtPhoneNbr.Text, this.txtUserName.Text, this.txtPassword.Text, out conn);
if (rc == 0)
{
try
{
TcpClient client = new TcpClient();
client.Connect("www.amazon.com", 80);
MessageBox.Show("Successful Connection!", "TCP Client Call", MessageBoxButtons.OK,
MessageBoxIcon.Exclamation, MessageBoxDefaultButton.Button1);
}
catch (Exception ex)
{
MessageBox.Show("Connection Failed! Reason=" + ex.Message, "TCP Client Call", MessageBoxButtons.OK,
MessageBoxIcon.Exclamation, MessageBoxDefaultButton.Button1);
}
RasWrapperII.RasHangUp(conn);
}
else throw new ApplicationException("Return Code: " + rc.ToString());

Thanks in advance for any help that someone can provide.

-Bill

It's not officially supported, I'm afraid. The 'Extra Dialling Commands' field is a field of the opaque structure pointed to by the lpbDeviceInfo parameter passed to RasSetEntryProperties which isn't officially documented. Strictly it can be whatever the TAPI (Telephony API) provider for this phonebook entry wants it to be.

For standard dial-up connections, though, the TAPI provider is the Universal Modem (Unimodem) provider. If you have access to the Windows CE shared source code, you discover that it's a DEVMINICFG structure. You'll have to see that source for the definition of the structure and how to use it.

The only supported way of editing this information programmatically is on Windows Mobile 2003 and later, using configuration XML with the CM_PPPEntries configuration service provider. However, normally WM2003 and later devices with a GSM/GPRS radio will ship with Phone Edition and offer a direct Cellular Radio TAPI Provider, which can be used with the CM_GPRSEntries configuration service provider.

Get Current Directory

Hi,

I am trying to get a sampleclient application for wince working. When running the app on the pocket pc the message is that it can not find a certain certificate file; however, even after putting the the certificate file in the same directory as the sampleclient app it still produces the same message.

How about changing the source (sampleclient.c file) to have a preprocessor command which outputs the current directory for running the app? Maybe the app runs from some other directory not so obvious. Also, what is the method of getting the current directory?

Thanks,

Pooyan

Win Mobile: How to draw an "always on top" graphical element?

Hey all,

I'm porting a small smartphone application to Windows Mobile 5/6. I am a bit stumped by the following:

The app consists of a small graphical rectangle which is always on top - basically a status bar. It should be painted on top of whatever else the win mobile os does. Ie. the win mobile OS works as usual with paint, input handling etc in everything it does, only with this custom graphical element overlay always painted on top of part of the screen.

Is there an elegant way of doing this?
(bonus points if it's possible to implement in managed / C# code)

Best regards,
