The ROM has to be built specifically for each model of device. Contact the device manufacturer to see if there is an OS upgrade available.
One of the major changes between Windows Mobile 2003 and Windows Mobile 5.0 is that the main file system is persistent on WM 5.0, that is, it is stored on Flash memory. This requires a lot more Flash than in WM 2003, and many 2003 devices did not have enough for WM 5.0 to be practical.

Hello,
1) What is the major difference from the speed(time consuming) and bulky/large data point of view dataset being sent as webmethod parameter (in soap body) and sending the dataset as attachments in VS2005 .netcf
2) If dataset sent in soap body i assume it gets serialized what happens in terms of attachments how is this sent over the wire?
3) Could you please list out various advantage and disadvantage between the two
Many thanks,
Regards

hi ,
i m use following code at click event of a button for display or hide a keyboard
<br />
If keyboardVisible = False Then<br />
mdChecking.SipShowIM(1)<br />
keyboardVisible = True<br />
Else<br />
mdChecking.SipShowIM(0)<br />
keyboardVisible = False<br />
End If
where mdChecking is module and contain following pinvoke function
Public Declare Function SipShowIM Lib "coredll.dll" (ByVal dwFlag As Integer) As Boolean
following function perform well. but when keyboard is displayed then a little icon is also associated with this SIP(keyboard)which also facilitate user to hide keyboard. so if user hide keyboard from icon then at this time my boolean variable is set to true(see above code) and this time if user once again execute the above code then keyboard is not visible.
so how can i remove this icon or how can i determine whether SIP(keyboard) is displayed.

Windows CE has no concept of the current directory. All paths must be specified completely, i.e. from the root of the file system.
We use the following code to get the path to the application EXE:
Dim path As String = System.IO.Path.GetDirectoryName(
System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase)

You need to call frmWizardForm1.Dispose() when the form is being closed, so it disposes all resources and the instance of that form. Then reload it, and you will be fine

Ok, in your code I see this line:
frmWizardForm1.Show()
You don't want to do that, change that to
frmWizardForm1.ShowDialog()
Also, be sure to have the Dispose method being called in the close of that form, and that should fix it. I didn't notice that the first time  Hope that helps

No problem, I'm happy to help. I don't understand the current problem though. I believe you are saying that If you use ShowDialog() then you have to close the first form before you can use your back & next buttons. Is that correct? Explain to me what this form collection does, and if you click back or next, is it supposed to open a new form(frmWizard2,3,4)?

I think, when you use form.close(), it is usually disposed, and you have to create a new form instance before you can use form.show() again. I usually use form.hide()/form.show() if I want to continue to use the same form again.

hi,
thanks for ur reply
First thing ,if i hide the form then my application is not listed in task manager window. second i does not create any instance of form. i am working only with form in coding(in place of creating object).

I am not sure I understand this right, but how do you show a form that doesn't exist ?
Additionally I believe, not only on PDAs, but on desktop windows as well, only those programs show in the taskmanager, that have a window, i.e. form open on the desktop.

Here's what i am trying to achieve
1. I encrypted/decrypted the entire soap body instead of encrypting single parameter value, this seemed to be worked and i am happy with that
So what i have is Two CustomExtension Class that Encrypts and Decrypts Soap body and works both ways (request and response)
2. Problem is when i use this above Webmethod along with another extension ie DimeExtension (Opennetcf) the flows from client end reaches till the server just before the Service's webmethod call the CustomExtension is hit which is fine but error's out at processmessage .BeforeDeserialize where i am trying to load the stream to xmldocument for decrypting
Error message :
' ', hexadecimal value 0x01, is an
invalid character
My guess is the DimeExtension is messing up the Stream , i was playing around with it and found there is "/f" in the stream , but am not sure as i am unable to Visualize Ws-attachment
How does the Soap Envelope looks if Binary attachments are sent along with it? i guess they are the out most part
<soapenvelope>
Could you please help to right direction?
Client Code:
[System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://tempuri.org/HelloWorld", RequestNamespace = "http://tempuri.org/", ResponseNamespace = "http://tempuri.org/", Use = System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle = System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
[OpenNETCF.Web.Services2.Dime.DimeExtension]
[CryptoExtension()] ----> CustomExtension
public new string HelloWorld()
{
DataSet ds = new DataSet();
ds.Tables.Add("tableTest");
m_attachdataset(ds);
object[] results = this.Invoke("HelloWorld", new object[0]);
m_retrieveattachment();
return ((string)(results[0]));
}
Server Code:
[WebMethod]
[ParamEncryptionExtension] ----> CustomExtension
public string HelloWorld()
{
DataSet dsrequest;
dsrequest=Class1.WSD_RetrieveAttachment();
DataSet ds = new DataSet();
ds.Tables.Add("responsetable");
Class1.WSD_AttachDataset(ds);
return "Hello World";
