Hi,
I need some basic information about Windows XP embedded - development:

- Do regular Win32-Apps run on Windows XP embedded?
- Is there a special SDK or can I use the "normal" Win SDK?
- Do I have to consider something special when developing?

Thanks,
Chris

Slider Control problem

I have added a slider control to my app and a handler for 'mouse capture release' (when the user lets go of the slider) using the 'NM_RELEASEDCAPTURE' notification and a function called OnNMReleasedcaptureSliderXXXX function.

However, when I compile it fails, saying 'NM_RELEASEDCAPTURE' : undeclared identifier .

I can't understand it. Any ideas why?

Thanks for any suggestions,

Ali

Right, that's pretty annoying as VS2005 lets you add the slider control to the dialog! D'Oh! | :doh:

Oh well, thanks for the info, Smile | :)

Write a gui-less exe to grab the screen, either using the "desktop" dc or from the video memory with GAPI. Save the resulting image in whatever format suits you. Assign a hardware button to start it.

Use the above mentioned exe or wrap the funtionality in a dll. Use RAPI (CeCreateProcess or CeRapiInvoke) to start the capture process. You can use CeReadFile to grab the resulting file or use IRapiStream to transfer the data directly.

RAPI.dll is installed with together with activesync, lib & headers should be shipped with whatever SDK you plan to use for your pda development under [SDK-PATH]\support\ActiveSync\

Not receiving messages

Hello. I know this is disturbing, but I have a CDialog window and I tried to overwrite the OnPaint message handler. However, the overwritten method is not being called, despite I added the ON_WM_PAINT. I tried with other messages: ON_WM_ERASEBKGND, ON_WM_LBUTTONDOWN, ON_WM_MOVE, and it is not working. Any idea?

The particularity of this dialog is that I have many CStatic with images, and one of such image fills the entire window.

Any help will be really appreciated.

Regards,
FG.

Hi, I already resolved the mystery of the lost messages. One of my CStatic covers the entire area of the window. I removed such CStatic and it worked perfectly.

It seems that since another window covers the CDialog, WinCE determines that there is no need for sending the WM_PAINT message to the CDialog. Weird Sniff | :^)

Missing Buttons & Check Boxes

Hi, I created a couple of dialogs for my application with group boxes, radio buttons & check boxes. When I run it the group boxes are there but the radio buttons & check boxes are missing!

I'm using Visual Studio 2005. I created the diaplogs using the wizard just like I would for a non mobile app, and when I run test dialog they are visible. Any ideas what I may be doing wrong?

Many Thanks,

Ali

Update: - I have found that my group boxes were covering the radio buttons & check boxes, which is why I couldn't see them. I guess I need to make the group boxes transaparent or put them 'behind the buttons' - any one know how I do that?

I don't understand because group boxes are normally transparent anyway! What use are they if they obliterate the controls inside them? Confused | :confused:

Thanks for any ideas,

Ali

You need to set the tab order so that the check boxes appear earlier in the tab order than the group box. The tab order determines the order that the controls are created in and therefore their Z-order.

Group boxes aren't generally used very often in Pocket PC applications - the .NET Compact Framework doesn't even have a group box control.

I didn't realise that. I even went and changed the tab order to put the group box first D'Oh! | :doh:

Turn off graphical inheritance

I have to have form2 inheriting all the methods and variable in form1. but I don't want to have the graphical stuff from form1. how to by pass that? because when i specify form2 inherit from form1 and run the program, it shows on the graphical components of form1 on form2.
Im using C# with VS2005

All controls are created in code in C#. The forms designer places the control declarations in the FormName.Designer.cs file, which you can see when you click the [+] next to your class in the Solution Explorer. This file contains the InitializeComponent method, which is called by the class constructor. Form2's constructor calls Form1's constructor, which calls Form1.InitializeComponent; then Form2's constructor calls Form2.InitializeComponent. You'll have to come up with a way of stopping Form1's InitializeComponent being called.

I would recommend moving the data manipulation methods and variables out of the Form1 class into a different class, making Form1 and Form2 use that new class, and removing the inheritence link between Form1 and Form2.

You can handle the WM_CTLCOLORLISTBOX message for the CListBox. Use GetStockObject to get a NULL_BRUSH and return that. Note that MFC, for legacy reasons, uses OnCtlColor instead - Windows 3.x used WM_CTLCOLOR but this was replaced by the new messages in 32-bit Windows because there was no longer room for all the parameters. Call your base class's implementation to get it to set up the other colours appropriately.

For a CListCtrl, you should be able to use SetBkColor(CLR_NONE). If that doesn't work you should handle the NM_CUSTOMDRAW notification.

Re: Auto connect to internet

Well, you can do one of the following:

a) Just make a HTTP-Webrequest, the default internet connection will be made when starting the request.

b) Use the connectionmanager: get OpenNETCF[^]. Add a Reference to the OpenNETCF.Net library.

the code for the connectionmanager is something like this:

<br />
                    cmManager = new ConnectionManager();<br />
                    cmManager.Timeout = 120000;<br />
<br />
                    try<br />
                    {<br />
                       //log.Info("Trying to make connection, attempt: " + i);<br />
<br />
                       cmManager.Connect(<br />
                                new System.Guid("436ef144-b4fb-4863-a041-8f905a62c572") // Internet GUID<br />
                                , false, ConnectionMode.Synchronous);<br />
                       log.Info("CONNECTION MADE IN " + i + " ATTEMPTS");<br />
                       break;<br />
                   }<br />
                   catch (InvalidOperationException e)<br />
                   {<br />
                      log.Debug("oeps, unable to make connection");<br />
                      log.Error(e.Message);<br />
                      log.Error(cmManager.Status.ToString());<br />
                   }<br />
     }<br />

As you see, the connectionmanager is called with a 'guid'. This points to a certain connection in the system. The one I use above is for 'The Internet' connection, found on every ppc/wm5-device. For a list of possible guid's use the following code:

<br />
                    string dests = "";<br />
                    DestinationInfoCollection dInfoCol = cmManager.EnumDestinations();<br />
                    foreach (DestinationInfo dInfo in dInfoCol)<br />
                    {<br />
                        dests += " \n" + dInfo.guid + " :: " + dInfo.description; ;<br />
                    }<br />
                    MessageBox.show(dests);<br />

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
