How do I set Network Management settings or make the dialog appear in C# on Windows Mobile?

Answer 1

You need to use the Connection Manager API to establish a connection. In fact, there is a flag you can set to stop the error notification!

Here is an article on how to use the connection manager with wininet. I assume you will have to P/Invoke the API.

One suggestion I would have, is to abstract use the connection manager out as much as possible and it use as little of it as possible. Connection Manager is not very nice to use and I beleave the current interface is being dropped in furture versions of Windows Mobile.

Update:

Calling DMProcessConfigXML is really easy from native code. Again I assume the P/Invoke of this function into C# should not be to bad. Following the link to see a simple example of calling this the DMProcessConfigXML. The had part is figuring out from the microsoft documentation what xml you want to send.

You basically need to go through the Configuration Service Providers MSDN documentation in whatever area you can to configure. If you are looking into network setup, I personally would not bother. It's a big hairy mess and is really only useful for setting up proxy setups for specific mobile operators and/or corporate network WIFI setups. If you want to setup general GPRS / Wifi connections, it's not that easy.

Update2: I should read the question more closely, I beleave the answer is NO to "modifying the network options", but "Yes" to creating whole new network setups. That's if I understand the spec correctly. I have only played around with setting up networks.

Hope that helps.

Answer 2

@MusiGenesis: I have the very same problem you have, so I am wondering if you were able to display the notification or not? If yes, can I know how?

Answer 3

In answer to your question 2, this code will show the connections control panel:

Process.Start(@"\windows\ctlpnl.exe", "cplmain.cpl,19");

A lot of the built in settings applets are shown through ctlpnl.exe. I got the magic number from the list here, not sure if it'll help, because you still need to guide the user through the rest of the comms setup.

With respect to your question 1, I have used DMProcessConfigXML and also config manager setup cabs to configure the comms settings (admittedly from c++, but looking at the api it should be straightforward to p/invoke as Shane has suggested). It was a while ago so I don't have any examples to hand right now, but we definitely got it to make new network settings and switch those drop downs to select the new settings. I'll see if I can dig up an example of the XML later.

It seems there is no need for P/Invoke, ConfigurationManager.ProcessConfiguration is the managed wrapper in the Microsoft.WindowsMobile namespace that calls DMProcessConfigXML.

I'm still looking for the right xml to send to it, most likely some combination of CM_Networks, CM_Planner and maybe some others... details are all here but the documentation is a little tricky to work out what does what, and I can't remember as it was a long time ago :(

Ok, after a little experimenting (as I didn't find the xml) here is some xml that you can pass to ConfigurationManager.ProcessConfiguration that will change the two settings:

This was taken from my wm 6 pro emulator, so you may need to play with the settings a little. It sets both the dropdowns to My ISP (the ADB0B001-10B5-3F39-27C6-9742E785FCD4 guid) Just change the guid in the type="HTTP-xxxx" and type="null-corp-xxxx" and ensure it matches in the srcId parm too.

I called ProcessConfiguration with this xml (and metadata set to true) to get a list of all the entries that were configured, it returns them in an xml doc.

<wap-provisioningdoc>
  <characteristic-query type="CM_Mappings" recursive="true"/>
  <characteristic-query type="CM_Planner" recursive="true"/>
  <characteristic-query type="CM_Networks" recursive="true"/>
  <characteristic-query type="CM_ProxyEntries" recursive="true"/>
  <characteristic-query type="Wi-Fi" recursive="true"/>
  <characteristic-query type="CM_PPPEntries" recursive="true"/>
  <characteristic-query type="CM_VPNEntries" recursive="true"/>
  <characteristic-query type="CM_NetEntries" recursive="true"/>
  <characteristic-query type="CM_GPRSEntries" recursive="true"/>
</wap-provisioningdoc>

You can either use that to see what the guids and settings are or look in the include files from the WM sdk as they are listed there for use with the connection manager apis.

One caveat is that I haven't tried to use these connections after messing with them, but the UI does change when you process the configs
