    - WAN communications We have a VB.NET application that runs on a CE.NET 5 device, and at present users return to the office to upload and download data by logging into the main SQL server. We will shortly need to accommodate users accessing the server remotely (from outside WiFi range) . What possibilities are there for this? I have looked at literature, and as far as I can see, I have 2 possibilities - GPS and internet. Our handheld device has an optional GPS module, but is it possible to connect the CE.NET device directly to the office network using a combination of the existing 802.11b module in the device, a wireless broadband router and VPN, or use an ftp site to transfer data. I can see these options being easier to implement and cheaper (which is the most important) than GPS. What hardware/software would I need for any of these options? I am completely new to this area, so any help would be appreciated. Thanks in advance. Andy Baker Tag: Check SD card Memory and Tag: 78725

    - Socket restart issue Hi All, I am working on a CF 2.0 C# application for windows CE 5.0 device. My application has a socket server feature in it and we have a Flash application as a socket client. The Flash client connects to the C# server and data flows between them. At some point in time, the C# app has to close the Flash movie and restart it at a later point in time. Here lies the issue. When the C# app relaunches the swf, the swf starts looking for the server. But the server stops listening to clients any more. I tried shutting down and closing the socket object and creating that object (with the same name) again and start listening, but it gave me a socket exception. Is it not legal to recreate the socket object with the same name? How else can I go about it? I cannot use new names each time I create socket object. Also, I cannot use different IP address or port numbers as they are hard-coded in Flash. Thanks, Krupa Tag: Check SD card Memory and Tag: 78722

    - Connecting PDA/Phone to Web Services using SSL? I am using the following code to make a connection to a remote web service running on my windows 2003 server. The server is in a domain using Certificate Services. I have assigned a certificate to the default web site and configured it. I can connect to the web service using IE, but when trying to make a web connection via my application, I get various errors. I can't seem to make it work. Here is a similar example to my code: service.Url = @"https://" + Server + @"/WebService1/WebService1.asmx"; System.Net.NetworkCredential NC = new NetworkCredential(); ServicePointManager.CertificatePolicy = new TrustAllCertificatePolicy(); NC.UserName = username; NC.Password = password; NC.Domain = domain; service.Credentials = NC; try { if (service.IsConnected()) { return true; } else { return false; } } catch(Exception except) { MessageBox.Show(except.Message); } return false; When I am not using https, things connect fine. When I use https, I get "Unable to read data from the network connection", inner exception is "the remote certificate failed validation procedure". Is there something I'm doing wrong, or is this simply not supported with Windows Mobile? I can't seem to find any clear answers out there. I have added the root certificate to my mobile device store and it doesnt change the error returned. Can anyone tell me how to make it work securly? I need to pass admin credentials around with other various sensitive data and I need a secure connection from the mobile device. Microsoft is doing it with Outlook, so you would think it should work.

    - HttpWebRequest Accept-Encoding: gzip Header Hi, I've developed a solution to call a webservice via HTTPWebRequest The IIS is configured to allow compression (gzip). The client application add to the request header the accept- encoding:gzip request.AllowWriteStreamBuffering = true; request.SendChunked = false; request.KeepAlive = true; request.Method = "POST"; // tell the HTTP server that the client accept compressed data request.Headers.Add("Accept-Encoding: gzipr\n"); I've tested with success the code on my laptop, but on my pocket Pc this does not work. I mean, i can successfully call the webservice but i never receive the contents compressed. In order to demystify this issue I've placed an http sniffer and came to the conclusion that when i run the code into my laptop the header accept-encoding is sent and from Pocket PC is not (this way the IIS cant know if the client allows compression). Investigating a little more i did the following: request.Headers.Add("Accept-Encoding: gzipr\n"); request.Headers.Add("TestHeader: okr\n"); Running this code in pocket PC i saw that he sends the "TestHeader" Header. He only omits the Accept-Encoding. Why is that? Note: This behaviour occurs on Compact Framework 1.1 and 2.0; on pocket pc 2003 mobile edition and on WinCE 5.0 What is happening? Can you help me?

    - Socketclient connection problems I am working on the new HTC P3600. In my VB (2005) project I am using the socketclient component to connect to the server via UMTS connection. It takes around 50-55 sec just to connect to the socket on the server and then the rest of the communication is done quickly. On the older model the S200, which had EDGE connection, to connect to the socket server took only 1-2 sec. I have also tested this odd behaviour with some other devices either connected with via GPRS or EDGE and everything is working perfectly. Where is the problem, the UMTS network or the socket component? Thx, Dule Tag: Check SD card Memory and Tag: 78699

    - Selectively italicizing ComboBox items I'm working on my very first Windows Mobile project. I need to selectively set the text of certain items within a ComboBox to be displayed in italics. I read up on ower draw for ComboBoxes only to learn that it's not supported in .Net compact framework. After extensive searching on MSDN, newsgroups, and the web I'm still not entirely sure how best to approach this. I'd prefer to customize/ override/handle events on the existing ComboBox rather than create a custom control from scratch. I've done a bit with customizing existing controls on the desktop by handling OnPaint and such. Can someone explain the best mechanism to accomplish what I need to do and give me a push in the right direction? I think I can take it from there. Thanks in advance.

    - DLLImport with relative Folder Hi Guys, I want to import some function implemented by C++; I have built my those function under VC++ IDE, I have created a DLL Folder on my DOTNET project,and added my DLL file into this folder. When I do deploy my Project on Simulator,I have found that My main Entry file is deployed with different loction with my DLL location, let's say: Program Files --mysolution--Main Entry File | ---DLL---mydll.dll File So when Main Entry call some function implemented by dll files, it can not find dll file. Since my DLLImport["mydll.dll",EntryPoint="EntryPoint"],I know the reason that is is because I dont write the correct path. Question: Can I write relative path on DLLImport or is it to be absolute file path? I prefer to relative path than absolute path, since it will make me feel flexible! If I can write relative path, how to write,I have googled it, I only find some absolute path writing.:( Sorry, I am totally new dotnet user. Thanks Tag: Check SD card Memory and Tag: 78662

    - Serial Port Issues Hi NG, I've recently taken on the task of creating some custom software for a Treo 750v. The Treo has a working serial port (tested with a terminal emulator) and is running Windows Mobile 5.0 with Compact Framework 2.0 installed. Lets start off with some background first.... For my first attempt, I attempted using the emulator, and the first issue I encountered was that I could not receive any data on the serial port (BytesToRead property was always 0, and yes I bound the emulator comport to a real comport in the settings). So, for the heck of it I compiled the same code, and ran it as a standalone app on windows XP. Everything worked great! So I finished developing the app, running into many minor issues, one of which was: serial.write(chr(data).toString) has a TX parity error 40% of the time. Switching to a byte array solved it (don't know why), and I went along my merry way. Anyway, the app is finished, and ready to be installed on the handheld device. I installed it, it fired up no problem, then as soon as communication begins I'm bombarded with frame error after frame error. Obviously it has to do with it being run on a handheld, and unfortunately I don't have another model handheld to test on. Anyone have any similar issues? -Thanks Tag: Check SD card Memory and Tag: 78658

    - Implementing SuspendLayout in CF 1.0 Hi, I have a 'core' code that runs in the main thread and it needs to be run without the other threads able to invoke their methods. Currently other threads are able to perform invoke since the 'core' code is using GUI methods such as Form.Hide() Using lock won't help here because it's not practicle that all the other threads will try to access the lock object before invoking (Since these are services for the application it will be a 'dirty code' to do this) What I'm asking is if theres an option/possiblity of implement/rewrite the suspend/resume layout methods that are not supported in the CF 1.0? I know the methods are supported in CF 2.0, but I can't migrate the code to CF 2.0, yet. And if it is supported in CF 2.0 doesn't it mean that it IS possible to find an API function that does that?

    - how to activate an application not a form Hi, How do i activate my application? I used GetForegroundWindow(), CreateProcess() , but nothing works fine. I'm only able to activate the current form. But not the application as a whole. To give in detail, my app contains multiple forms, like form1 creates form2, form2 inturn creates form3. Suppose now form3 is the current active form and my app goes background as i click on 'today' item from 'Start'. Now if CreateProcess() or GetForegroundWindow() is called, it displays form3. Its fine until that. But as i close form3(), this should show up form2. But it does'nt. It just shows today screen, no form. What i want exactly is when i activate a form in my app from settings->memory, it works just as fine as the application was never put in background. I want to acheive the same. PLZ suggest.

    - Visual Inheritance in User Control I am creating a CF application using VB.Net 2.0 and VS2005. I am trying to create a heirarchy of controls to give my application a common look and feel. Here is what I have so far: public class ctrlBase inherits UserControl public class tabBase inherits ctrlBase public class pageMain inherits tabBase When working with tabBase, I can correctly see the formatting and controls on ctrlBase, and then add controls that should be accessable to all decendants to tabBase. However, when I go into the designer for pageMain, instead of seeing the controls from tabBase, I am again presented with ctrlBase and its controls. Is there some setting I need to make to allow inheritance deeper than one level? I appreciate any help you can offer. Mike Tag: Check SD card Memory and Tag: 78612

    - .NET 2.0 WebService Hi, We're migrating our PocketPC application frrom Compact Framwork.NET 1.1 to 2.0 but are experiencing a "Timeout" error with one of our web methods. From our testing we do not think it is anything to do with a timeout but rather the size of one of the parameters. The paremeter is a string of apporx 48k. which we pass in the web method and get the error (there is very little processing on the string by the server). However if we reduce the size of this parameter by half the call succeeds ! We have no problems on CF 1.1 Are there any settings/limits on the PDA side which could cause this problem especially differences between .NET 1.1 and 2.0 ?

    - Mouse Capture Hi, I have code that "pops up" a listbox control. It's a child of my topmost form, and appears on top of other controls. I would like to hide the listbox when the user taps on an item in the list (on MouseUp), or taps outside the listbox (on MouseDown). Of couse, ListBox doesn't support the mouse methods. Setting Capture=true and attaching a MouseDown delegate to the main form only works to a point (if the user taps in another control, or on the menu bar, there's no notification). I wrote a native DLL that calls SetWindowsHookEx and passes mouse messages to a managed MessageWindow. It turns out that mouse hooks are not implemented in WinCE. Am I missing something, or have I done something wrong? I see that the ComboBox drop-down list manages this, as does the SysDateTimePick32 control. It looks like OpenNETCF ApplicationEx class would allow me to create an application-wide message filter for the lifetime of the ListBox. Could someone confirm that this will pony up those pesky mouse messages? -- David Tag: Check SD card Memory and Tag: 78597

    - Binary storage Hi all I am currently using SQLite as my database, which I found to be much faster than SQL CE, however I still require faster binary storage. My database consists only of a single table create table Instances ( Oid INT Primary Key, InstanceType Text, InstanceData BLOB ); create index InstancesInstanceTypeIndex on Instances(InstanceType); I serialise / derserialise my objects myself and store my business object ID (int) in Oid, the Type.FullName in InstanceType, and the object's serialised data in InstanceData. My requirements are 1: Add a new record 2: Update a record by OID 3: Get a record by OID 4: Get a list of OID with a specific class name "InstanceType" 5: Get the highest OID in the database I might need to remove a record in the future, but at the moment I don't need to. The InstanceData consists of variable sized data. I am wondering: A: Is there an embedded DB for CF that is faster than SQLite? B: Is there a non-DB way (single file) that I could achieve this which would be faster? Any help would be appreciated. My XML->DB import routine is taking an hour and this is far too long.

Qualche giorno fa ho voluto installare IE7, tutto è filato liscio e in pochi minuti ho avuto il mio bel browser fiammante :) Però da quel momento IE non fa altro che lamentarsi su gran parte degli stessi siti *Microsoft* che prima visitavo! Un esempio su tutti: http://v4.windowsupdate.microsoft.com/en/default.asp IE7 mi dice che le protezioni non permettono di utilizzare i controlli ActiveX. Ho cercato in rete tutti i modi di convincerlo: aggiunto il sito tra quelli attendibili, spuntato tutte le caselle che riguardavano i controlli ActiveX... almeno IE6 diceva "oh! va che qui c'è 'sto controllo, lo eseguo lo stesso?" adesso ho solo una pagina bianca :( Poi non capisco il motivo di avere un'impostazione della protezione per l'area internet e per i siti attendibili/con restrizione... i siti non sono in internet??? :) Ciao Tag: Check SD card Memory and Tag: 78531

    - Custom column formatting [C#, CF 2.0 SP 1] Hi there, I'm having some troubles properly formatting strings in a DataGrid component. The situation is as follows. My datatable contains status information in numeric form. I would like to present this information in the form of a short word (e.g. 'new') in a column in a datagrid that is bound to the datatable. I'm planning to make this fancier in the future, but for now it'll suffice. Looking at the API I was unable to find a way to simply "inject" a custom formatter delegate or object. Somewhat desperate I turned to the heavy-duty solution of implementing my own column style which overloads the Paint method. The code is heavily based on an example I found at: http://blogs.msdn.com/netcfteam/archive/2006/04/25/583542.aspx The relevant code looks like this: protected override void Paint(Graphics g, Rectangle bounds, CurrencyManager source, int rowNum, Brush backBrush, Brush foreBrush, bool alignToRight) { DrawBackground(g, bounds, rowNum, backBrush); bounds.Inflate(-2, -2); RectangleF textBounds = new RectangleF(bounds.X, bounds.Y, bounds.Width, bounds.Height); object cellData = PropertyDescriptor.GetValue(source.List[rowNum]); Color foreColor = owner.ForeColor; string s = FormatText(cellData, ref foreColor); if (foreColor != owner.ForeColor) foreBrush = new SolidBrush(foreColor); //MessageBox.Show(string.Format( // "calling DrawSting: s = {0}, owner.Font = {1}, foreBrush = {2}, textBounds = {3}, fmt = {4}", // s, owner.Font, foreBrush, textBounds, fmt)); g.DrawString(s, owner.Font, foreBrush, textBounds, fmt); } protected virtual void DrawBackground(Graphics g, Rectangle bounds, int rowNum, Brush backBrush) { //if (alternatingBrush != null && ((rowNum & 1) == 0)) // backBrush = alternatingBrush; g.FillRectangle(backBrush, bounds); } protected virtual string FormatText(object cellData, ref Color paintColor) { return cellData == null ? NullText : cellData.ToString(); } The FormatText is overloaded to provide more sophisticated translation, I'm fully aware I don't need a custom formatter if the translation only requires ToString(). :-) Unfortunately, this code does not work. In fact, not even the MessageBox is shown (if I uncomment those lines). All I get in the designated graphics canvas is a diagonally drawn cross. I checked all the parameters passed to DrawString for equality to null, but all look fine. Does anyone have an idea why this code doesn't work? Even better: is there a simpler way to provide custom formatting to an existing column style? It would be nice if I could change the colour as well, but a simple int->string translation would be a step in the right direction. Niels Tag: Check SD card Memory and Tag: 78530

    - Radio buttons do not maintain mutually exclusive if a label is in the panel Hi. Can anyone shed a clue on this? If i have 2 panels both with 2 radio buttons. One of them containing a label inside the panel, and one does not. When selecting the radio buttons, teh one with the label , will eventually have both radio buttons selected, and thus is no longer mutually exclusive. The one without a label seems to work normally.

    - Problem with SqlTypes.SqlBinary declaration in VS2005/CF2/WM5 I'm working my way thru upgrading our codebase and have come across an odd one! I have a method that is returning a variable of type SqlBinary but gives the following compilation error... Error 3 The type 'System.Data.SqlTypes.SqlBinary' exists in both 'c: \Program Files\Microsoft Visual Studio 8\SmartDevices\SDK \CompactFramework\2.0\v2.0\WindowsCE\System.Data.dll' and 'c:\Program Files\Microsoft Visual Studio 8\SmartDevices\SDK\SQL Server\Mobile \v2.0\System.Data.Common.dll' This is a psuedo-snippet of the code... using System; using System.Data; using System.Data.SqlTypes; using System.IO; namespace TimeDrive { public class FluxCapacitor { public SqlBinary StarChartData(string filename) { } } } I've tried declaring the return var as 'system.data.sqltypes.sqlbinary' and also removing the 'using system.data.sqltypes' line, but neither resolve the error.

I don't know of any APIs that would cater to your needs. However, you
can find out whether or not you have an SD card by doing

if(Directory.Exists(@"/Storage Card"))

You might as well check out DirectoryInfo class to see if it has any
memory related properties.

Hi Jeff,
PInvoke GetDiskFreeSpaceEx to get the storage card free space, follow
Krupa's thread for checking the directory exist.

Code snippet:

[DllImport("coredll.dll")]
private static extern bool GetDiskFreeSpaceEx(string
lpDirectoryName,out ulong lpFreeBytesAvailableToCaller,
out ulong lpTotalNumberOfBytes,out ulong
lpTotalNumberOfFreeBytes);

Usage:
ulong freeBytesAvailable, totalBytesAvailable, freeBytesTotal;
if (GetDiskFreeSpaceEx(storagePath, out
freeBytesAvailable, out totalBytesAvailable, out freeBytesTotal) ==
true)
{
totalBytes = Convert.ToInt32(totalBytesAvailable);
availBytes = (int)freeBytesAvailable;
}

Hope this helps,
Cheers,
Arun

No, that folder is localized. Use FindFirstStorageCard()
