    - Cannot connect using GPRS and System.Data.SQLClient to remote SQL Server Hello I am developing a Pocket PC (XDA 2 - Windows Mobile 2003) application that needs to connect to a remote SQL Server 2000 database via GPRS. I am hosting a test database myself so have full control over the environment. The desktop machine currently has SQL Server 2000 (mixed mode authentication) and IIS with SQL Server 2000 CE Agent installed and all the latest service packs. The problem I am having is that I cannot connect to the remote database using System.Data.SQLClient namespace when connected via GPRS. I can use SQLClient happily when connected to the desktop machine via Activesync ? even if the desktop SQL Server does not have SQL Server CE Agent installed. However if I try the same code to connect via GPRS it refuses to connect. I can however connect via GPRS using RDA, if SQL Server CE Agent is installed and setup, but I was hoping to use the added flexibility of the SQLClient namespace. I've read that SQLClient only works in fully connected scenarios. Does this mean that it only works through Activesync? Do I need to use a different connection string when connecting over GPRS than through Activesync? Thanks for your help Paul Tag: Turning device on/off at predefined time ? Tag: 36042

    - Send SMS with number of sender Hello *, I created a class, which allows me to send a SMS. I used the sendSMS example from Microsoft (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnnetcomp/html/netcfSendSMS.asp) Okay, it works fine, I can send a SMS, but only without my own number. The receiver gets an anonymous message. I already tried to change some options in the code, but the SMS is still missing the number of the sender. My code: unsafe public bool sendSMS(string sPhoneNumber, string sMessage) { System.IntPtr hSms = IntPtr.Zero; IntPtr res = SmsOpen(SMS_MSGTYPE_TEXT, (IntPtr)SMS_MODE_SEND, ref hSms, IntPtr.Zero); if (res != IntPtr.Zero) return false; Byte[] bDest = new Byte[516]; Byte[] bDest2 = new Byte[516]; fixed (byte* pAddr = bDest) { fixed (byte* pAddr2 = bDest2) { byte *pCurrent = pAddr; IntPtr myNumb = SmsGetPhoneNumber((IntPtr)pAddr2); Marshal.WriteInt32((IntPtr)pCurrent, (int)AddressType.Unknown); pCurrent +=4; foreach (byte b in Encoding.Unicode.GetBytes(sPhoneNumber)) { Marshal.WriteByte((IntPtr)pCurrent, b); pCurrent++; } Byte[] ProvData = new Byte[12]; byte[] bMessage = Encoding.Unicode.GetBytes(sMessage); int nMsgSize = bMessage.Length; res = SmsSendMessage(hSms, myNumb, (IntPtr)pAddr, IntPtr.Zero, bMessage, (IntPtr)nMsgSize, ProvData, (IntPtr)ProvData.Length, SMS_DATA_ENCODING.SMSDE_GSM, (IntPtr)SMS_OPTION_DELIVERY_NONE, IntPtr.Zero); if (res != IntPtr.Zero) return false; SmsClose(hSms); return true; } } } Any ideas, what I'm doing wrong?

    - Managing db connections on the device I have a singleton class in my data layer that opens a SQL CE db connection and assigns the connection to a member variable. This way I can open the connection only once in the application and avoid having to close and re-open it. In my data layer I have a Customers class that is derived from a BaseTable class. The BaseTable class has a DBConn property that calls a GetInstance of the connection singleton class and returns the reference to the open connection. The question I have is: have I created any conflicts with the garbage collector or am I mismanaging connection resources? In short, is my approach reasonable here, any gotchas I haven't seen? My code in Customers class looks like this: public DataTable TableAll() { try { // here's the DBConn property that gets the db connection SqlCeCommand cmd = DBConn.CreateCommand(); cmd.CommandText = "Customers"; cmd.CommandType = CommandType.TableDirect; SqlCeDataAdapter da = new SqlCeDataAdapter(cmd); DataTable table = new DataTable(); da.Fill(table); da.Dispose(); cmd.Dispose(); return table; } catch (Exception ex) { throw new Exception(ex.Message); } } here's DBConn in the singleton Connection class: private SqlCeConnection m_conn; public SqlCeConnection DBConn { get { if (m_conn != null && m_conn.State == ConnectionState.Open) return m_conn; else return OpenConnection(); } } Thanks, Jeff Tag: Turning device on/off at predefined time ?

    - How to overcome background color related issues in asp.net - listbox on CE based browsers Hello Gurus, I am into a new arena of Windows CE/embedded XP. While launching an asp.net application into Window CE4.2 IE browser, I got into a problem with background of listbox. Though I noticed from books that background color property is not available for CE.net for .net controls, I wonder how it impacts on IE browser. I am still under assumption , it should not impact, since the web controls are flushed into IE based controls, and not Winforms. This example illustrate it further. <asp:listbox id="lstSample" runat="server" Width="400px" Height="310px" BackColor="SaddleBrown"></asp:listbox> In the Windows CE - IE browser, it gives two different behaviour. 1) If there are no contents in listbox, the background is colored with saddlebrown, which is good. 2) If there are some items in listbox, the background is half-colored white(one having contents), and other half with saddle brown. (THIS IS THE PROBLEM) Any suggestions how to overcome this problem. Thanks Whidbey Wave Tag: Turning device on/off at predefined time ? Tag: 36005

    - Strange RAS/WebService problem We have developed a VB.net application for Pocket PC devices, which download data from a VB.net webservice. We are currently implementing the RAS dial-up functionality (using the Sapphire libraries). On a test device (a Symbol) with a built-in modem, this works fine. The connection is made, and the data is downloaded from the webservice. However, on the actual device (an intermec 700c), which dials via a Siemens MC35 modem, we get a WebException on the call to the webservice, even though the connection is made successfully. Apart from using different hardware, the only difference is that the Symbol modem requires the extra modem dial-string command of +GCI=FD in the dial up connection, to set the region to the UK. If we try this on the Siemens modem, we don't even get a dial tone. Has anybody used this type of modem, or can tell me the correct dial-string commands, or has any idea why this should make a difference to a web service call? Thanks, Ian.

    - Optimizing for speed Due to time constraint, my last project (first one in VB.NET for us, I might add) was done 'quickly' rather that right, meaning that it is 'good enough' for the client but not the kind of project one feels proud of after delivery. I happen to have some spare time on my hands which I plan to spend optimizing the whole thing just to improve myself. One of the things I know we didn't do right, simple as it is, is the display of SQL.CE based data on grids. We just execute a query, grab all records, put them in rows and display the grid - slow as hell as you can easily guess. Given you have the data in one or several tables, what is the fastest way to display it on a grid? Fastest as in 'fastest availabity to the user', so retrieving records as needed by user interaction is fine. This is actually my first idea. Also, suppose you need one of the fields from the query not for display but for something else (i.e. you can't just feed the results to the datagrid, even if it's possible to do so, which I'm not sure). All suggestions welcome, I have the time to try them all. Tag: Turning device on/off at predefined time ? Tag: 35972

    - HP Mobile printing : System.MissingMethodException' exception I am trying to provide printing capability using HP Mobile Printing SDK from VS.net 2003. This SDK available to people who submit a business case proposal. Let me explain what is happening. It comes with a dll into which the code makes P/Invoke calls for providing printing facilities. The dll is made part of the project and set to content so that it is moved to the PDA when it is diployed. When I run the application on the PDA it is raising this 'System.MissingMethodException' exception' when we try to call one of the methods that they say exists in the dll. In a FAQ on HP's web site, they say the following: ********** Q: I've added 'mobile printing' to my application. Now, when I click the 'Print' button, I get a 'Missing Method' exception. How do I fix this? A: If you have followed the procedure correctly then the way you are launching the application may be causing the problem. The print application needs mPrintWrapper.dll in its path. If you are using a shortcut or a program menu to launch the application then make sure that the path is correctly set so that mPrintWrapper.dll (and CSMobilePrintClassLibrary.dll or equivalent library if you are developing VB print solution) is in application's path. *********** I am not using a short cut and the dll is copied into the directory where the exe is installed. My question is, how and where you set the path so that it can find the dll. Does any body have any idea about this. Your comments are appreciated.

    - Control names in VB Conpact Framework I'm try to develop an easy way to get a complete list of all form names, their control names and the controls text/caption properties as a starting point for an internationalization project on a fairly large project. It looked like it could just put a call to a module level sub and passing Me in all the Form.New's and then in to mod level sub enumerate the controls on the form and write them to log file. Although I can get the control type and there is a Form.Name and Control.Name property, the Name properties are not supported in Dot Net. Is there any way to get a form name or control name out of compact framework? I am taking this approach because we have fairly large project which will be internationlized to several languages and I wanted to develop a means to provide the ability for end users to modify translations instead of using a resource file. I take this approach in all my desktop code and it works great and then end user's love being able to do their own translations.

In addition I programmatically set the relevant Instl registry key to 0 to disable the dialog box informing me that the application is already installed. This works OK. However I cannot disable the dialog boxes asking me do I want to replace the already existing files with those newly extracted from the cab file.

Everything works fine normally, however, on occasion it is required that I output a character to the custom device, collect the response data, process the data, then repeat the process any number of times (done in a thread). On occasion the custom device sends extra undesirable data (variable amount) to the PDA after I have collected the good data and before I output my new character to the serial port.

The fixes in .NET CF 1.0 SP3 (http://blogs.msdn.com/onoj/articles/178293.aspx) seemed like they might fit our issue, so we installed the .NET CF 1.0 SP3 beta on to one of our devices (custom device running Windows CE.NET). Unfortunately, we still experienced the issue. One item that I thought may be cause for concern is that the namespace of the object (app.foo.bar.com) and the array of oject (webservices.baz.bar.com) in the WSDL were different. Might this be an issue? Here is a snippet from the WSDL (some names have been changed): <types> <s:schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="http://app.foo.bar.com"> <s:import namespace="http://schemas.xmlsoap.org/soap/encoding/" /> <s:complexType name="SomeSpiffyObj"> <s:sequence> <s:element name="SQLTypeName" nillable="true" type="s:string" /> <s:element name="assetStsInd" nillable="true" type="s:string" /> <s:element name="finalDest" nillable="true" type="s:string" /> <s:element name="legNbr" type="s:int" /> <s:element name="operDate" nillable="true" type="s:dateTime" /> <s:element name="rteID" nillable="true" type="s:string" /> <s:element name="schedDTM" nillable="true" type="s:dateTime" /> <s:element name="tripID" nillable="true" type="s:string" /> </s:sequence> </s:complexType> </s:schema> <s:schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="http://webservices.baz.bar.com"> <s:import namespace="http://schemas.xmlsoap.org/soap/encoding/" /> <s:complexType name="ArrayOf_tns2_SomeSpiffyObj"> <s:complexContent mixed="false"> <s:restriction base="soapenc:Array"> <s:attribute d7p1:arrayType="s0:SomeSpiffyObj[]" ref="soapenc:arrayType" xmlns:d7p1="http://schemas.xmlsoap.org/wsdl/" /> </s:restriction> </s:complexContent> </s:complexType> </s:schema> </types> *** End snippet ** If the namespace issue is not a problem, what else might be problematic?

    - Managed SocketException at HttpWriteStream:Write+0x185 Hi. While stress testing an C# CF app designed to upload binary files, I have been connecting, disconnecting, and then reconnecting my IPAQ (Pocket PC 2003) to the network. Sporadically I get the following exception: A Managed SocketException occurred at HttpWriteStream::Write+0x185 Unknown error (0xffffffff) HttpWriteStream::Write+0x185 HttpWriteStream::copyTo+0x28 HttpWebRequest::startSending+0x5d HttpWebRequest::startReceiving+0x53 Connection::startReceiving+0x29 WorkItem::doWord+0x36 Timer::ring+0x59 I have found a posting on the web ( http://dotnet247.com/247reference/msgs/29/147616.aspx ) which describes an almost identical exception which someone found in the Compact Framework Final Beta. Mike Boilin from MS replied that it was a bug in the compact framework. It appears that the bug still is not fixed. Can anyone point me to a workaround? Thanks...

    - Loading Resource Icons using LoadIcon from coredll.dll Does anyone know how to load an icon (that is a resource in my project) using the LoadIcon function from coredll.dll? I can load the application icon using the value #32512 as the second parameter, but I would like to be able to load different icons for use with Shell_NotifyIcon(). Thanks for any help.

Hi,

I am making an application for work studio. This means the user
is asked a question at random time within the workingday.

When in idle mode the device should be turned on/off by the application.
However I am not shure how to approace this task. Any sugestions would be
appriciated.

Thanks Henrik.

You can turn off the device by simulating a VK_TPOWER keypress by P/Invoking
the keybd_event API function.

You can use CeRunAppAtTime to schedule your application to start up again
(and wakeup the device) at a predefined time. You'll find this ready-wrapped
for the Compact Framework in OpenNETCF.Win32.Notify namespace
(www.opennetcf.org/sdf/). There is a SendKeyboardKey implementation in
OpenNETCF.Win32.Core. You may need to check the header files for the value
of VK_TPOWER (which is equal to VK_F18).
