Hi!
Im developing in for windows mobile 6 and Im using native C++ code with msxml2.h, to receive xml objects from RSS.
When an rss-server doesnt send out a header content-type with MIME-type of xml (like "Content-Type: text/xml") I get problems when trying to fetch the xml object from the request object (pIXMLHTTPRequest->responseXML;) and the xml doesnt seem to include any tree-data.
I can still see the actual source-xml data through pIXMLHTTPRequest->GetresponseText();
When the content-type header is set to an xml mime-type I can retrieve the tree-structure from pIXMLHTTPRequest->responseXML. One solution would be to change the server content-type but that is not always possible, and content type from rss is nowadays "application/rss+xml".
Example theese 2 rss are identical but only one is fetched correctly in responseXML
http://91.90.27.250/panel/working.php
http://91.90.27.250/panel/notworking.php
My code is basically (the rss includes "item" tags)
HRESULT hr;
MSXML2::IXMLDOMDocumentPtr pXMLDoc = NULL;
MSXML2::IXMLHTTPRequestPtr pIXMLHTTPRequest = NULL;
hr=pIXMLHTTPRequest.CreateInstance("Msxml2.XMLHTTP");
hr = pIXMLHTTPRequest->open("GET", L"http://test/~joynes/rssValid.php", false);
hr = pIXMLHTTPRequest->send();
pXMLDoc=pIXMLHTTPRequest->responseXML;
MSXML2::IXMLDOMNodeListPtr nlItems;
nlItems = pXMLDoc->getElementsByTagName("item");
MSXML2::IXMLDOMNodePtr nodeItem2;
while(SUCCEEDED (nodeItem2 = nlItems->nextNode()) && nodeItem2 != NULL)
{
printf("SUCCESS!!!!!\n");
}

I have developed an application for Win Mobile 5.0 in Visual Studio 2008. My application involves an access of data from SQL server mobile database. My application can access the data from the database when deployed on the Win mobile 5.0 pocket pc emulator. Now i have created a CAB file of my project in Visual Studio 2008 and then deployed this CAB file on Windows Mobile 6.0 (I am using HTC P3450 handset). When i run my application on the Win mobile handset i cannot access the data from sql server mobile database. What is the reason? Do i have to copy the SQL server mobile database to the Win mobile?
When i deploy the application on the emulator i can see the database in Query Analyser 3.5. I then connect the database to the project through Query Analyser 3.5. I am using .Net CF 3.5 and hence i have installed its cab file on the handset. But i could not see the Query Analyser 3.5 on the handset. Please help.
Thanks in advance

Hi Deepali Khalkar,
If your are able to view your database then your application should be access the Database through application. I Hope your database path is some different location.
Let me know whats exception you are getting.

Hi Khatri Mitesh,
In this case you have to make version system in your application when your application run check your own version with web service method, if the version is different then download your application and install it self.
see this link

Hope that this may be help.

You can use P/Invoke method GetDiskFreeSpaceEx() to do that, it's very useful.

Hi
Want to show popup notification for "low battery" in .net compact frame work 1.0, is there any notification class in .net compact frame work 1.0
Thanks in advance

Why are you still using the 1.0 Framework? It is harder to develop for the 1.0 Framework and it isn't supported on all current devices. Your 1.0 app may run under the 2.0 framework in compatibility mode but you'll need to do more testing to ensure that the differences in the framework don't surface through your application.
The SystemState class has a member called BatteryStrength. You can add an event handler to get notification when it changes by a significant amount.

OK thanks for your reply. If i install Windows CE 6.0 on my device, can i use .net 2005? Because in .net 2005 there is no option for Windows CE 6.0 when i search under Create Project-Visual C# - Smart Device - Windows CE 5.0
I am confuse that which .net version i have to use for Windows CE 6.0.
Please update me
Thanks

For Windows CE to be available in the new project types you need to have the Platform Builder installed. The appropriate platform builder installation comes with the development hardware you've purchased.

I want to deploy an application developed in Visual Studio 2008 under smart device on Windows mobile 6. I have used .NET 3.5 while developing the application. Is there any need to install .NET Compact Framework 3.5 on Windows Mobile 6? Please provide the required URL to download the .NET CF 3.5
|
|
|
|
|
If you are deploying the application using Visual Studio it will automatically detect the .Net CF version installed and install a newer one if needed. If you need to manually install the .Net CF onto another device. You can find a link to the distributables in the article Windows Mobile Development Without Visual Studio[^]

Thanks a lot. I found the link very useful. I could install .net CF 3.5 on Win mobile 6.0 handset.
My application involves an access to the data from SQL server mobile database in Visual studio. When i run the application on Win mobile 6.0 handset i cannot access the database but i can see the forms designed in my project. Do i need to install SQL server compact edition cab file on the handset? I went to the path C:\Program Files\Microsoft SQL server compact edition\v3.5\Devices\wce500. Here i found many folders containing cab files for SQL server compact edition. Please let me know which is the file needed to install. Also while running the application on Win mobile 5.0 emulator i used the connect the database to my project through Query Analyser 3.5. I could not see the Query Analyser 3.5 on Win moblie 6.0 handset.
Please help with this.
Thanks in advance.

The pre-installed version of .NET Compact Framework in Windows Mobile 6 is version 2.0 SP1.
So if you are not using any APIs that are new to 3.5 since 2.0, I would suggest that you simply change the target framework in Visual Studio.
