    - HTML control and non-existing files My HTML control works with local HTML files. In case the user clicks on a link towards a non-existing page, I would like to get a message and create the appropriate file, allowing the control to navigate to the newly created file instead of posting an error message. What I found out so far, that I could do this using the MN_HOTSPOT notification. However, I still have to figure out, how to do this exactly in .NET CF 2.0. But the more important question for me is, would this really allow me to stop the naviagtion, create the non-existing page, and continue to navigate to it, when it is created ? Or would I be rather unable to stop the navigation process ? In case this approach is not applicable, do you know of others ? Thank you.

    - Problem using slide out keyboard and resize event FYI. I have an application that was migrated to VS 2005 and now using a pda/phone with windows mobile 5.0. The way the app functions is that there is a main menu and other forms are opened depending on the user. This means there may be 3 or 4 windows open. We have our own "x" exit buttons to close the form and the app is designed to close them in order. If you open the main menu, and then select a path so that there are 3 or 4 forms open and then open and close the slide out keyboard, it causes the resize event to fire in all of the open forms and rearranges the order in memory. Thus, when you close the form that has focus, you don't necessarily go back to the form you are expecting to see. Tag: database connection through Wireless Lan is very slow Tag: 67931

    - Options when Button.PerformClick is not available? I'm working my way through my first significant compact framework C# app and I've got a question (actually many questions, but I'll just start with this one). It would be very handy in my application to programatically "Push" a button on a form. In "Normal" dot net, I'd use Button.PerformClick, but in CF2.0 I don't have that option apparently. I understand that I could restructure the code and call the same functions, but in my case it would be easier to just press the button. What is the cleanest way to "Press" the button? Ideally it would maintain the same sequence of events as a real button press. Any suggestions? Thanks, John Kelsey Tag: database connection through Wireless Lan is very slow Tag: 67928

    - SqlCeResultSet and datagrid Hello, I've read a few times [1] that you can bind the DataGrid to an SqlCeResultSet in a way that when the DataGrid is first displayed only the visible data is retrieved from the (Sql Mobile) database. Further data is only retrieved when the use scrolls the datagrid. I have not been able to reproduce this behaviour. What I've tried is: a) 1. get an SqlCeResultSet by using SqlCeCommand::ExecuteResultSet() 2. set DataGrid::DataSource to the resultset b) used Visual Studios Data Source (with the datasouce designer configured to use the SqlCeResultSet instead of the usual DataSet) to create an DataGrid by drag'n'dropping it on a form Both test retrieved all data from the database before displaying the resultset. So my question is: how can I make the DataGrid only retrieve the absolutely neccessary data from the db and retrieve furhter data only when the user scrolls the DataGrid? Thanks Ben [1] e.g. here: http://groups.google.co.uk/group/microsoft.public.dotnet.framework.compactframework/browse_thread/thread/a124ddaac6bc38c7/547330b85d2e54e6 Quote Ilya Tumanov [MS]: "For SQL Mobile (SQL CE 3.0) you can use new SqlCeResultSet class which supports data binding directly. It's really fast if bound to DataGrid because only visible rows would be actually retrieved. " Tag: database connection through Wireless Lan is very slow Tag: 67927

    - An alternative for (small) Modal Dialog Box in compact framework ? Hi, I'd like to add to my PPC app a kind of modal dialog window, which does NOT stretch over the whole display. Unfortunately, that's exactly what all new forms in compact framework do by default. (This default rule perpahs made sense with small displays, but currently on PPC with 640x480..?) The only workaround I found so far is to set form.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None; but then the form/window is borderless, has no caption, etc. So my idea is to use WinCE APIs DialogBox(), EndDialog(), and GetDlgItemxxx(). However, I can't figure out how to test this in emulator, because it is not clear in which LIB or DLL these APIs are exported. I tried COREDLL and DLGMGR, but without success. Also, I didn't find a way how to make my VS 2005 PPC project aware of my compiled resource file (res) with dialog window template. I can add it to the project as a file, that's not the problem, but then I would expect to see and be able to use defines from this resource in other project files, but it does not work :-( So I would be really gretaful if someone could post a code snippet, or point me to a doc, which explains this.

    - Distribution I have a PPC app I have written, it's going to be installed on a few thousand PPCs within the same company. I have created an installer application in VS for this app. What I want to know is how can I ensure that DotNet V2 + SqlCE 2005 is installed as part of the same installation? I only need the data part of SqlCE, not replication etc. Basically I'd like to have only a single CAB file to install everything, it will make implementation much easier.

    - Menu and toolbar at the same time? I'm new to the compact framework and have some basic questions about forms. I use VS2005 and CF 2.0. 1. When I place a MainMenu and a ToolBar on a form they are both positioned at the bottom, the menu is at the left and the toolbar is at the right. When I add items to the menu the toolbar gets smaller and smaller. Can't I position the toolbar above the menu? 2. If I use a Panel as a toolbar substitute, is there any way I can create a button with an image on it? Button don't have a Paint event. 3. Are there issues with transparency for toolbar buttons in CF 2.0? 4. Is it possible/advisable to get the Window handle to a control in CF and use SendMessage and other API functions? 5. If I switch to C++, which newsgroup is most appropiate for disscusing Windows CE programming in C++ (I can't find any)?

    - IO performance WM2003 vs WM2005 Hi! I've a WM2003 and a WM2005 machine and see some major performance improvements when reading/writing to a SD-card using the WM2005 compared to WM2003 machine. The SD-card is of the same brand and the WM2005 machine has a much slower processor 194MHz comparde to 400MHz on the WM2003 machine. The WM2005 machine has CF2.0 installed in ROM, but the application is written for CF1.0 so it shouldn't use and CF2.0 libraries, right? Is this a know WM improvement, or as it something to do with CF (allthough I believe my CF1.0 app couldn't benefit from CF2.0) / Peter Tag: database connection through Wireless Lan is very slow Tag: 67904

    - File comparison I am trying to buid an auto update feature for my application. I am implementing it by comparing two files, one from the web server and one from the local. I thought of 3 possibilities which any of them didn't help. 1 - Compare the version of the assembly. Worked perfectly, however I couldn't overwrite (it has a new version) because the file is already in use. And I couldn't unload the assembly once loaded. I also tried appdomain and still can't do because the lack of appdomain functions in compact framework. 2 - Compare the file with GethashCode() which leads to different versions of gethashcode because server side version and compact framework version of that function gives totaly different results. 3 - Compare by the creation time. This one also fails, because lastcreation time of file does not have set property. What else can I do to say that those files are identical and no need to update ?

At my case, I open the port that will receive a lot of connections, before all the process I close it with a .shutdown() and .close(), at the clients I close the stream and another things, at this point ok, the problem appear when I want to open the port again it give me the SocketException error numer 10048 that say "This port is in use.". And don't open it, but if I open the port execute the process and close my application, they close the port immediately and don't have this delay, it appear when I open the port and don't close the application.

    - VS2005 - Merge Rep Performance. (Previously posted in the â??microsoft.public.sqlserver.ceâ?? newsgroup but got no response.) Ok, so I successfully converted my VS2003 CF application to VS2005 including an update from SQL Server CE to SQL Server Mobile Edition and an update of the merge replication (MR) agent from sqlcesa20.dll to sqlcesa30.dll. Both the old application and itâ??s converted counterpart are hitting SQL server 2000 SP4 on the back end. It appears to me that MR is slower on the VS2005 platform. The old app would replicate in 8 sec. and the new app takes 13 seconds when hitting the same servers. The SQL that produces the replicated tables is the same for both replication setups and has been optimized. I would like input from those who have implemented CF applications on the VS2005 platform that use MR. Have you found it as robust as VS2003? How have you found the performance? Is it faster if you hit SQL Server 2005 on the back end, and slower if you are hitting SQL Server 2000? In hindsight would you have made a different choice? Has MR improved or regressed with the new version supported by VS2005? Bill Tag: database connection through Wireless Lan is very slow Tag: 67852

    - Emulator won't connect to desktop web service form VS2005. Create web service on dev machine using file save. That launches a virtual web site with a random port (is possible to a static port). This is useful for when IIS is not installed. In a student lab this is useful. The ws will only alllow localhost connections, which the emulator is not. A suggestion was to download cassini and change one line to enable unsecure access but this doesn't have Frontpage extensions installed so can't do VS dev on it. Really want to avoid installing a web server. I remember that I you can run CF apps on the desktop subject to some restrictions. The CF web service client app did work on the desk top (Run the compiled .exe) .. talking with the desktop (virtual) web service. I also remember that with beta versions of VS2005 this desktop mode was a smartdevice option for debugging (Removed at RC1 level I think). There were some settings that could restore it. Q What are the settings that will allow debugging of a CF app to running on the desktop (for debugging) directly from VS 2005? This is a classic case of where it would be useful .. desktop debugging of CF app. -- David Jones Senior Lecturer School of Electrical & Computer Engineering RMIT University +61 3 99255318 Tag: database connection through Wireless Lan is very slow Tag: 67846

    - Open new Form: Old Form "goes to background" Hello I have a problem using .NET CF. If I open a new form with "settings.showdialog" and I stay on the new form for 5-10 minutes, then the old form disappears. If I close the settings-form, then I see the Today-Screen instead of the old form. Must be something with timeout... I now tried to use this: <DllImport("coredll.dll", EntryPoint:="SetForegroundWindow", SetLastError:=True)> _ Public Shared Function SetForegroundWindow( _ ByVal hwnd As IntPtr) As Boolean End Function <DllImport("Coredll", CallingConvention:=CallingConvention.Winapi, CharSet:=CharSet.Auto)> _ Public Shared Function FindWindow(ByVal lpClassName As String, ByVal lpWindowName As String) As IntPtr End Function Public Shared Function BringFormToFront(ByVal FormName As String) As Boolean Dim hwnd As IntPtr hwnd = (FindWindow(Nothing, FormName)) SetForegroundWindow(hwnd) End Function after settings.showdialog I use: BringFormToFront(me.text) But this doesnt work either?! Any solution to this problem? Thanks Kenny Tag: database connection through Wireless Lan is very slow Tag: 67836

    - Help! OnClick event in VScrollBar in .Net Compact Framework Hi! I tried to catch the Click event from a VScrollBar control but the Click event is not rised. MSDN says that OnClick event is suported by .Net Compact Framework and, in this case, I supose that the click event sould be rised bu VScrollBar. In this case I derived a class from VScrollBar and I overrided the OnClick protected method. I failed again because the overrided OnClick method is never called. I derived another class from Control and I overrided again the OnClick method. In this case the overrided OnClick method was called. Please, there is anybody who can tell me what is happening with OnClick method and Click event for VScrollBar control? And what should I do to catch the Click event for VScrollBar? Or what should I do to make it work OnClick overrided method in a derived class from VScrollBar? I use Windows XP Professional, Visual C# fromVisual Studio 2005 Professional Edition, .Net Compact Framework 1.0 or 1.1 Thank you in advance!

    - Memory problem under Windows CE .NET Hi, I have written a C# program under a Windows CE .NET PDA but when I'm using it for a long time, I have a memory problem : not enough "program memory" is allocated, please increase the quantity of memory. This information is displayed in a messagebox but I can't get focus on the messagebox. If I look the memory allocated on the PDA, I can see that the maximum of "program memory" is allocated. The only solution I have is to make a cold boot of the PDA. There is probably another solution ? Thanks in advance for any answer.

    - how to work with Splitter (or SplitContainer ?) I am trying to create a simple Form using .NET CF 2.0 that displays two Treeviews Side-by-Side in case the device is running in landscape mode. When the user switches to portait mode, the two treeviews shall be displayed on top of each other. Also the user should be able to resize the two controls by moving a horizontal (or vertical) bar. I felt that the splitter is the perfect control for that. But unfortunately I am not sure what to do to make it work. No matter what I do, the splitter can not be resized. I set treeview1.dock to top, I set splitter.dock to top and I set treeview2.dock to fill. What else do I need to do to make the splitter resizable and to chnage the oriantation upon switch to landscape mode. Is t here an event for the landscape/potrait mode change ? Also the msdn says that Spiltter is now obsoloete and I should now use the SplitContainer. But the Viusal Designer of VS 2005 does not have support for the SplitConatainer. At east I cannot find it in the toolbox. Tag: database connection through Wireless Lan is very slow Tag: 67811

    - Serialization in CF problem OK I'm not sure how explain this without giving hundreds of lines of code. basically I have a main class that I want to serialize. It's constructor creates more classes that I also want serialized. public Mainclass{ public subclass1 class1; public MainClass() { class1 = new subclass1() } } //Now that subclass wants to create more classes public subclass1 { public string blah; public subclass2[] class2array; public subclass1() { blah = "blah"; class2array = new class2array[2] for (int i =0; i<2; i++) { class2array[i] = new subclass2(i.ToString()); } } } //which creates public subclass2{ public string name; public subclass2(string inName) { name = in Name; } public subclass2() { // default constructor } } Now when I serialize this thing I'd hope I get back something like <?xml version="1.0" encoding="utf-8"?> <MainClass xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001...> <subClass1> <blah>blah</blah> <subclass2> <name>0</name> </subclass2> <subclass2> <name>1</name> </subclass2> </subClass1> </MainClass > Running this in the regular framework I do get that back However running this in the compact framework I get back <MainClass xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001...> <subClass1> <blah>blah</blah> </subClass1> </MainClass > The difference seems to be coming from within the loops but I can't see what Is going wrong there. Is this a known thing? I didn't post my actual code since it's miles long but this is the general idea of what is failing. If I throw in a debug message in the constructor for subClass2 It does fire so it is getting all the way down there it's just not showing up in the XML at the end. Any idea? sorry for the cross post but the XML guys seem to not answer many CF questions. Tag: database connection through Wireless Lan is very slow Tag: 67797

    - screen resize event to capture landscape mode - Mobile 5.0 VS 2005 We have a system that uses a main menu that remains in the background while successive forms are displayed. So effectively, when one form is loaded is runs on top of whatever screen was previously running. When the user closes a screen using our "X" exit button, we close the form and the previous form becomes active. I am using the resize event to redraw the screen when the user drops the keyboard down (mobile 5.0 vs 2005) it works fine most of the time but occasionally the main menu's resize event kicks off and causes another screen to be loaded. Is there anyway to prevent this? Is there something that can check if the form is the current form when the resize event kicks off to bypass running any code? Thank you.

    - Exploding CAB files with Rapi Using the Rapi Class in the OpenNETCF.Communication.library I have come up with the following code which copies a CAB file to a PPC and then explodes it. The explosion in turn produces another CAB file and when I try to explode with the same process it fails (the CAB is good as it can be exploded manually on the PPC). Can anyone advise what I am missing? string cCE = "EyeMHere.cab"; if (!m_rapi.DeviceFileExists(cCE)) { m_rapi.CopyFileToDevice(@"C:\EyeMHere\EyeMHereCab\Release\EyeMHere.Cab", "EyeMHere.cab", true); } if (m_rapi.DeviceFileExists(cCE)) { m_rapi.CreateProcess("wceload.exe", cCE); } //Up to this point the code works fine and the target CAB is exploded..... However, it won't work again..... cCE = "\\Program Files\\GpsLibCE.arm.CAB"; if (m_rapi.DeviceFileExists(cCE)) ///this evaluates true { m_rapi.CreateProcess("wceload.exe", cCE); //this line is processed but nothing happens... } Any ideas/suggestions? -- Thanks in advance.......

Hello!

The problem is: too slow filling DataSet when device (PocketPC) is
connected to sql server through Wireless Lan.
Device shows excellent connection to Access point. I tried to copy
large files through ActvieSync and through Wireless Lan. Through
Wireless Lan it takes about 1.5 times slower.

But filling DataSet takes 30-60 times slower then throgh ActiveSync!
The table (actualy it is a view) has about 6000 rows. When the divice
is connected through ActiveSync the DataSet is filled for about 1-3
seconds. But when the device is connected to PC through Wireless Lan it
takes 1-2 or even more minutes.

What is the reason and is there any solution of this problem?
