    - How to let Connection Manager know RAS connections Hi~ I used RAS API to create DUN connections programmatically on CE4.2 according to Alex Gusev's method (http://www.codeguru.com/Cpp/W-P/ce/pocketpc/article.php/c7355/) . It worked fine, but when I immigrated it to Mobile5.0/Maganeto, here comes the problem: the connections are not shown in GUI, in other words, the Connection Manager don't know my RAS connections although they exists already. Why? What difference is there between the Connection Manager Models of the two version? Thanks in advance :) Regards, Emily Tag: Detecting a hardware key beeing pressed and hold Tag: 98155

    - Please help me make setup .inf for CAB Hi, I am trying to make a setup cab. I have looked for simple sample, but only found one for pocket pc. I tried modifying it for my own use, but when I install it, the phone asks me all kinds of questions as to where I wish to store this info, on the phone, or on memory card. Is this possible? I don't want any of these questions. The cab should just install silently, using the directories that I specify. I know that users may want different, but this is something specific and it needs to be installed on the phone. I have only 2 files: MyApp.exe MyFile.data I wish to make a CAB file, so both files are copied to: \Program Files\MyApp And shortcut is made in the Start Menu with text "Start MyApp". That is all.. The cab should install silently. No interaction with user. This is for SmartPhone 2003. Can someone help me write up a simple .inf file to generate the CAB?

    - COM: return full path of a caller (ASP) Hello All, I'm trying to write an ATL COM to be used with an ASP on Windows CE Environment. I want to get the full path of an ASP file which calls the COM dll. In my COM, I have a method called "MapPath" which is meant to return the full path of an ASP file. STDMETHODIMP CFile::MapPath(BSTR *strVal) { AFX_MANAGE_STATE(AfxGetStaticModuleState()) // TODO: Add your implementation code here TCHAR filepath[MAX_PATH]; ::GetModuleFileName (0, filepath, sizeof (filepath)); CComBSTR bstr (filepath); *strVal = bstr.Detach(); return S_OK; } The ASP file instantiates the COM object and calls the method. Set objFile = CreateObject ("Object.File") ==> Response.Write objFile.MapPath Set objFile = Nothing When the asp file invokes the method (indicated by an arrow) I expect the method to return the full path of the ASP file ("\Windows\www\wwwpub\file\test.asp"). However, the MapPath method returns "\Windows\services.exe". I suppose there should be more lines of code to retrieve the caller's full path but don't know what and how. I'm very new to VC++. Could you post some code example here please? Thank you very much, Chan Tag: Detecting a hardware key beeing pressed and hold Tag: 98127

    - custom CBitmap class In an effort to make it easier for me to work with bitmaps, without MFC or ATL, I created this class. Nothing spectacular, but I'm wondering if this leaks memory or needs improvement. The thing I find most ugly in writing classes to use with native code, is the HINSTANCE required for many functions.. getting this HINSTANCE seems to be done by storing this in a global variable and refencing it. I store it in HINSTANCE g_hInst; This isn't very portable, because my classes then need to reference to this by defining extern HINSTANCE g_hInst; Shouldn't there be a way to get the instance handle through some API's instead ? Anyway, most important is to make sure this class is usable and doesn't leak any memory.

    - WSPStringToAddress problem in LSP Hi all I have a LSP in PPC. It seems that "WSPStringToAddress" function is always failing because its getting an URL. But this function doesn't resolve URLs. It just converts dot format numeric address to socket address format. What can I do in LSP to avoid this failure? Actually my real problem is, For some reason "the connection arrow icon at the top of the device is always broken even though ANY medium is connected and working fine and the LSP gets all the traffic properly". I went thru all the calls and this is one call that always failed. I am not sure this is the one causing the problem but atleast if I make this fucntion right, who knows, connection icons might be OK :-) I really appreciate any help.

    - Killing Notification dialogues Hi, i have an app i wrote which can intercept the hardware keys and do something. One of the "something" i would like to do is close dialogues when a certain key is pressed. How can i do this? By "dialogues", i mean modal forms AND those bubble notifications on the taskbar. i know how to find a window by it's class, and i know how to send a WM_CLOSE message. i also have a key handler class that can handle the hardware keys "globally" (meaning it doesn't matter what app i am in, i detect when a key is pressed)... my problem is, i can't seem to detect when one of those lil taskbar bubble notification dialogue appears and i cant seem to "find" them. I assume when the show up, the have the focus, since if i am typing and they appear, i have to click back to where i was to continue typing. However, GetActiveWindow does not return a valid Ptr/Handle when they pop up. I also cannot find them because i do not know the Window Class for these notification dialogues and i am currently not able to get Remote Spy going on my machine for some reason. any assistance would be greatly appreciated Tag: Detecting a hardware key beeing pressed and hold Tag: 98086

    - Is there maximum packet size for GPRS transmission? Hi, I just wrote an application for PocketPC 2003, or to be exact, my newly bought Mini O2. There is a TcpClient on the O2, while server application on a PC. If run using WiFi adapter connecting to its public IP (Server on PC), it works.... without any flaw... except initial connection is abit slow like 2 seconds compare to direct private LAN WiFi. And it work..... The problem arise when I am using GPRS. I found while receiving the packet half way, the functions terminated and was catched with errors. So I am interested to know if there is any untold maximum packet size for GPRS? If so, I will re-write some sub logic to transmit my data by multiple of smaller blocks. If you are curious, my original packets are relatively small, around 3kb~12kb.... It is why I did not write the code to send via multiple small blocks. And it prove to work on WiFi. So it must be something to do with GPRS.... Hope some GPRS gurus here can give some lights..... Thanks for reading... Tag: Detecting a hardware key beeing pressed and hold Tag: 98085

    - TAPI Support in Ppc [The following query is also posted on microsoft.public.pocketpc] Hello Experts, Forgive me for asking such a generic query, this more of an implementation issue. We're currently under planning stage to develop TAPI components for both PocketPC and PC. We've also observed TAPI's availability in two versions i.e. 2.x and 3.x. This is leading us to a confusion of, which one to use!? One of the decision factors can be, which one is more used/supported, both in terms technical and system compatibilities? So, it is very important to know about TAPI's support for PocketPC; 2.x or 3.x? I hope my english isn't too bad or I can re-phrase the query set to get more explanation :) Any comments/suggestion will be helpful for me.

    - moving Bitmap between managed and unmanaged code I am trying to move a Bitmap between managed and unmanaged code, so that I can use the Imaging API. The latter is a series of COM interfaces, so I am trying to use it from a dll written in C++. At the moment, I am trying to have the Imaging API create a thumbnail, and display it in managed code. What I have done is: 1. Create a Bitmap in managed code (C#) 2. Use Bitmap.GetHBitmap to get the Bitmap handle 3. Pass the Bitmap handle to a dll procedure 4. In the dll procedure, a. Load the bitmap into a Memory DC b. Use IImage->Draw to draw the thumbnail (previously created in the IImage) to the Memory DC c. Then clean up and return to the calling C# code 5. Display the Bitmap in response to the Paint event in the C# code What happens is, a black bitmap is displayed. No doubt my understanding of how all this should work is in some way flawed, but this P/Invoke stuff is confusing, and I'd appreciate any assistance. I've included some of the code below. C#: [DllImport("dplib.dll")] public static extern void testProc(IntPtr bptr); Bitmap bmp; public ThumbViewer() { InitializeComponent(); bmp= new Bitmap(100, 100); testProc(bmp.GetHbitmap()); } C++: extern "C" __declspec(dllexport) void WINAPI testProc(HBITMAP hBmp) { IImage *pImage; . . .

    - Camera on iPAQ has anyone managed to use the built-in camera on the hp ipaqs (eg. rx3715) without using the pay-for-sdk from hp? is there a DLL that can be invoked? on the actual ipaq, the default software for the camera is "hpcamapp.exe". would there be a way to disassemble the executable to work out what's going on or would this be too difficult? (if you're wondering, im a student and hence dont have enough spare cash to purchase the 200$ sdk - im trying to build an app that can do simple image processing for use with lego mindstorms stuff) Tag: Detecting a hardware key beeing pressed and hold Tag: 98042

    - Saving power and the battery while programming for Mobile 5.0 Hi, Are there any backgrounders available about best practices where it comes to saving power -and the battery while programming with Visual Studio 2005, the CF 2.0 beta and the Mobile 5.0 SDK? Kind regards, Tony Thijs Tag: Detecting a hardware key beeing pressed and hold Tag: 98038

I managed to use RegisterHotKey to get WM_HOTKEY messages. But that's only
good for short key presses. What I haven't figured out yet is how I would
detect a hardware key beeing hold for a while before it is released again.
Right now, holding a hardware key on my HP rx3715 triggers a secondary
application that can be configured through the Buttons settings by the user.

Can anyone point me into the right direction?
