    - How to debug while using true network [evc4.0 and PPC2003] I hope to debug while using true network, but I found that the ActiveAync would disconnected while logining GPRS network. Changing connection thru "WORK" or "INTERNET" is no use to solve this. Is that true? or any option can set to solve this? Thanks. Tag: When trying to visually design... Tag: 102582

    - SIP Icon Not Initially Showing In my Pocket PC app I have the main form come up and then on top of that I display a smaller form, designed to resemble a dialog box. But when this 2nd form appears, the small SIP icon in the lower right does not display. What's the best approach to refresh/redraw the screen? I'm thinking of doing this before displaying my smaller dialog box and am thinking that may reveal the SIP icon. -- Robert W. Vancouver, BC www.mwtech.com Tag: When trying to visually design...

    - Mobile Equivalent of Enum.Parse? In my WinForms app I'm loading a value from an XML file and converting it to an Enum type I have called "ProductID". Here's the line of code I've used to accomplish that: SysInfo.Data.Admin.ProductID = (DataObjects.Constants.ProductID) Enum.Parse(typeof(DataObjects.Constants.ProductID), table.Rows[0]["ProductID"].ToString(), true); One of the key things here is the use of 'Enum.Parse'. I'm now tryng to do something similar in my Pocket PC app but I discovered that Enum.Parse does not exist in the Compact Framework. So I'm wondering how I could accomplish this. In essence, I'm trying to convert a string to an Enum type. -- Robert W. Vancouver, BC www.mwtech.com Tag: When trying to visually design... Tag: 102563

    - PCMCIA stream driver with Mobile 5.0 problem Hello, We developed a PCMCIA stream driver a couple years ago and it was working just fine with 2002 and mobile 2003. We just got the Axim X51 with Mobile 5.0 and we appear to be having problems with the PCMCIA interface. After playing around with the registry keys I finally got my driver to load properly, and it appears to be returning a proper handle when I call CreateFile. Also the WriteFile returns successful, however there is no pin stimulation on the CF port when I look at it on the logic analyzer. Also another thing I noticed is that when you plug any type of card in to the X51 the CF port stays powered. It never use to be like this. What has changed that is not allowing me to talk to the port? Is anyone having to redo there PCMCIA drivers for Mobile 5.0? Thomas Tag: When trying to visually design... Tag: 102552

    - OMA Client DM xml format and SyncML questions Hi, A couple of device provisioning questions... OMA Client DM xml format questions: When I attempt to query for device information, the command states that it successfully completes, but the output file that is generated is an exact copy of my input file?? Below is the xml command I am attempting to push <wap-provisioningdoc> <characteristic type="DeviceInformation"> <parm-query name="Product" /> <parm-query name="AvailableRam" /> <parm-query name="TotalRam" /> <parm-query name="AvailableStorage" /> <parm-query name="TotalStorage" /> <parm-query name="BacklightACTimeout" /> <parm-query name="BacklightBatteryTimeout" /> <parm-query name="BatteryStrength" /> <parm-query name="ProcessorType" /> <parm-query name="ProductVersion" /> <parm-query name="OperatingSystem" /> <parm-query name="OperatingSystemVersion" /> </characteristic> </wap-provisioningdoc> Other queries (i.e., security settings, certificates, ...) work as expected, but this and a simple query of the alarm status return the input files as their output. SyncML questions: I am attempting to build OMA DM compliant xml commands and apply them to my mobile devices (both smart phone and pocket pc) using rapiconfig.exe, but whenever i attempt to push this xml command to the device, i always receive a "Config failed (0x80004005): Unspecified error" error message.

    - Uninstall CAB from PocketPC I have run a CAB for a VB .NET application. It installs the app and the app runs. Now I have updated that app. I uninstalled (via Remove Program) and the original version of the app appears to have uninstalled (i.e. not available anymore through the Programs screen. I then sent a new CAB to the device and ran it. It appeared to run fine. However, when I start this new version of the app (after removing the old version and installing the new version) ... I *still* see the old version!! What gives? The Remove Program function doesn't appear to *really* remove the program and a new install does *not* replace the old program!

    - SQL Server Mobile 2005 distributables... Hopefully this is an easy one.. I want to distribute, with my application, everything that a user needs to install on a freshly hard-reset device, in order for my app to open an SQLCE 3.0 (Server Mobile 2005) database. For example, after a hard-reset, if I install "sqlce.wce4.armv4.CAB" on a device, then a user can happily open an .sdf file using my eVC 4.0 program. I've written an equivalent for SQL 3.0, which works fine on a device after VS2005 has deployed .Net CF 2.0, and a range of SQLCE 3.0 libraries, but obviously, I just want to ship out (a) as little as possible (b) just .cab files that MS has authorised software developers to distribute themselves. What .cab files do I need, and where can I find it/them ? Mike Tag: When trying to visually design... Tag: 102539

    - How to know when foreground window become some dedicated application like pocket IE Dear all, My application/driver would like to get a notice when the foreground window become some dedicated applications like pIE or pWord. Right now I implement it in this stupid way: use a while loop in a thread to call GetForegroundWindow() and check if the handle the same with the handle I get with FindWindow(_T("IExplore"), _T("Internet Explorer")). This method costs some CPU resource even the while loop check it every one second. Is there any better way to do this? like getting a message or what when pIE or pWord become foreground window or at least get a message when foreground window changes then I can go check it if it's pIE at that time.

    - ActiveSync and USB client - Moble 5.0 vs. Pocket PC 2003 Hi, I'm trying to rewrite an application from Pocket PC 2003 to Mobile 5 that uses USB to ActiveSync. There are been some major differences. . . For PocketPC based PDAs (Compaq 3*, HP 55*, ASUS MyPal) we used a driver that offers serial communication via USB. It is found in the registry on [HKEY_LOCAL_MACHINE/Drivers/BuiltIn/USB] and referred to in [HKEY_LOCAL_MACHINE/Drivers/Active] which shows if the driver is activated. The driver is in the file bvd_udc_ser.dll In Mobile 5 the driver used by ActiveSync is in [HKEY_LOCAL_MACHINE/Drivers/BuiltIn/usbfndrv], which means that it is not a pure "stream driver" (with the pre-fix COM). This is a problem for us since the Pocket PC driver is deleted. The driver "usbfndrv" is visible in [HKEY_LOCAL_MACHINE/Drivers/Active] in the registry We hope that it is possible to activate the driver [HKEY_LOCAL_MACHINE/Drivers/USB/FunctionDrivers/Serial_Class] that is in Mobile 5. The problem it that it does not seem to be in the platform build. (since it is not in [HKEY_LOCAL_MACHINE/Drivers/BuiltIn]). The dll that it wants to use is named "serialusbfn.dll" but we do not know if it is in the OS-build. Where can we find "serialusbfn.dll" and do we have to deactivate "usbfndrv" (there is OS call)? Or, can we use the "usbfndrv" API directly to build something like a "stream driver"? Best regards, /hf Tag: When trying to visually design... Tag: 102527

    - Many questions regarding development of applications I am new to developing database applications for the PocketPC OS. I have been reading some of the topics on the newsgroups and have formed questions I hope this group can answer. I know my clients will be purchasing the Dell Axim X51 handheld which will be running Windows Mobile 5. I have MS Visual Studio .Net 2003 Professional and would like to use it to develop a "Smart Device Application" that would collect data to be transferred back and forth to an MS Access 2003 desktop database program. My questions are these: 1. Will an application developed with Visual Studio .Net 2003 Professional still run correctly on Windows Mobile 5? 2. Will Windows Mobile 5 still have support for Pocket Access (.cdb)? 3. If Windows Mobile 5 does not have support for Pocket Access (.cdb) then if I use SQLCE is there a simple way to transfer the data from my "Smart Device Application" to the MS Access 2003 program on the desktop. The user of my application will not have SQL Server to interact with SQLCE. 4. Will/Does the final release of Active Sync 4.x support .cdb files? Thanks, TD Tag: When trying to visually design...

    - managed vs native I am in the process of starting a new application targeting Mobile 5.0. Creating an managed C# application seems like a nice way to go since it is primarily a GUI application. However, I am not certain about the support of certain APIs in an managed application. For example, I would like to use EDB for data storage but all the information I have found on it is for an C++/native application; no mention of how to use it in a managed project. Also, I would need the ability to take in digital signatures done with a stylus. It would seem simple enough to use DirectDraw for drawing and saving the result as a image. However, I am not certain of the managed support for that. Would it be better to use a native project instead of an managed project? As you can see, I am pretty new with Mobile development so I would appreciate any insights. Thanks. Tag: When trying to visually design... Tag: 102502

    - Can I ( how do I ) do the requested PDA programming project? I have been asked to consider doing a PDA based programming project, and since this is a new area of development for me I was hoping someone could tell me if what I am being asked to do is possible etc. Over all project description: This is a data capture application, think of it as an ongoing survey. Every so often ( several time a day ) the PDA needs to 'wake up', play a sound to notify the user, then ask the user a series of multiple choice, true/false type questions. Next after a few days the PDA will be brought to a location for the data to be dumped into a laptop/desktop system for data analysis. This is for a 'medical' research study, the idea is to ask how the subject is feeling etc so we can see how the treatment is working. There is of course all kinds of details like data encryption, data storage etc. but those tasks I feel that I am capable of handling. My developmen status: While I have been developing for 25+ years, for the last ~15 years I have been doing mostly Visual FoxPro ( or it's earlier versions ). I have recently been learning .Net and C# but I am a beginner at best with it. OOP and general programming skills I am advance at, so I will be doing lots of what is the command to 'X'. Furthermore I have never owned and only play very limitedly with PDAs of any type. My Questions: a) Is my assumption that using 2003 .net ( or even the 2005 beta .net ) will allow me to 'easily' program a pocket PC based PDA b) Can the application wake up every so often to alert the user? I'm thinking that for power management reason it would have to power down for a while. Maybe PDAs can run for a week with out having to shut down. I expect a weeks is about the time lapse between data dumps. The again the PDAs will most likely be recharged each nght. Side question if some other application is running on the PDA ( There should not be, but lets be prepared ) can this application keep running in the background and come forward to get it's survey questions answered. c) Since this application is the only thing that needs to run on this PDA, what is the least expensive model that I should purchase. ( This project might need up to 80 PDAs ) d) Should I consider other PDAs and Oss like Palm? Would this result in significant hardware/software costs reductions. e) Is there anything obvious that I missed? Thank you so much for your time. __________________ Anthony T.

    - Ambitious project - comments? I have about two months of free time coming up and I want to wade into a programming project I've been thinking about for awhile. Before I say what I want to do, however, let me say what I have now as background. I've written an app for my iPAQ 1910's & 1930's that we use here in my business. It's an OOP Win32 C++ non-MFC app developed with eVC3.0. It uses ADOCE3.1 to interface with an Access DB (CDB) file. This Access file transfers to and from my desktop system via ActiveSync 3.8.0. On the Desktop, I interface with the Access DB (MDB) file via the Microsoft Office 2002 Access program and some VBA code I've written. Also, my desktop Access file is transferred out to my website where I've written ASP code that allows users to search my database to see what I have in stock. All of this works OK. But, there are parts of it that are a pain. For example, only one copy of my DB can be the 'live' copy at a time. Moving the 'live' Access DB file to the Desktop causes my desktop's version to loose its Primary Record Keys and to forget its Relationships. And, as I'm not the world's best VBA programmer, the tools I've developed on the Desktop end are a bit rough whereas the stuff I've written on the iPAQ side does precisely what I want because I've programmed Windows Win32 OOP C++ for years. So, this is what I'm thinking: --------------------------------- (1) Goal: Replace Access on the PPC side with SQLce. Assumption: I'll still be able to use ADOCE3.1 to interface with the new SQLce DB from my current code. Advantages: I've heard that SQLce is a better tool on the iPAQ. (2) Goal: Replace ActiveSync transfers via USB with my own custom TCP/IP code transfers via 802.11b. Assumption: None that I know of other than that I'm capable of doing this (I've done some network programming). Advantages: With full control over all details of the sync process, I'll be able to merge DB changes made on anyone of several PPCs with the desktop DB smoothly. These syncs will be able to automatically happen whenever a PPC is within range of the Desktop's AP. The Desktop version of the Access DB will stop losing its Primary Record Keys and forgetting its Relationships because I'll be updating it record by record in-place rather than replacing it wholesale with a copy from the PPC. (3) Goal: Cease using the Microsoft Office 2002 Access program and the VBA tools I've developed to interface with the DB on the desktop end. Replace these with a Windows OOP Win32 C++ non-MFC app of my own creation that uses ADO to interface to the desktop Access DB. Assumption: None that I know of. Advantages: This will allow me to interface with the desktop Access file exactly as I want to. (4) Goal: Because I'll be writing a Win32 OOP C++ non-MFC app on the desktop side, it will be able to serve both as the sync master coordinator and as my interface to the desktop version of the DB. Assumption: None that I know of other than that I'll need to have a good grip on coding multiple threads of execution (which I do). Advantages: A single point of interface on the desktop end customized as I want. (5) Goal: Stay with PPC code development using eVC3.0 rather than upgrading to later development environments. Assumption: That I can do everything I want on the PPC end with my existing eVC3.0 and ADOCE3.1 tools. Advantages: I understand this stuff well now and I don't know of anything in the later development environments that I really need. (6) Goal: Stay with VC++6.0 on the desktop side rather than upgrading to later development environments. Assumption: That I can do everything I want on the desktop end using my existing VC++6.0 tools. Advantages: I understand this stuff well now and I don't know of anything in the later development environments that I really need. ------------------------------------ That's it. There's a lot of parts to this idea and I'm looking for folks to poke holes in it if they can so I don't have to discover oversights the hard way later. Thanks in advance, Dennis Gallagher www.woodscreeknursery.com Tag: When trying to visually design... Tag: 102476

    - Questions: WM 5.0 and ActiveSync 4.0: how to control how often it syncs? With my new Dell Axim X51, ActiveSync 4.0 appears to sync every 5 minutes or so even though the only desktop ActiveSync provider configured is my own. The ActiveSync Tools => Schedule... menu item is greyed out in the desktop ActiveSync. Question: For WM 5.0 and ActiveSync 4.0, is there anyway to programatically set how often my desktop ActiveSync provider is automatically initiated by ActiveSync? Question: Is there anyway to enable the ActiveSync desktop Tools => "Schedule..." menu item, and use this same dialog box for my own desktop ActiveSync provider? Question: Is there anyway for my code to know when a sync is initiated automatically versus when the end-user clicks on the desktop ActiveSync "Sync" button? Question: Are there any related registry settings for controlling how often ActiveSync 4.0 syncs for a WM 5.0 device? Thanks. Tag: When trying to visually design... Tag: 102469

I am inserting a new row this way: private void mInsert_Click(object sender, System.EventArgs e) { try { DataRow dr = this.ldb.DohvatiDataSet.Tables[tableName].NewRow(); dr.BeginEdit(); for(int i = 0; i < this.ldb.DohvatiDataSet.Tables[tableName].Columns.Count; i++) if(!this.ldb.DohvatiDataSet.Tables[tableName].Columns[i].ReadOnly) dr[i] = this.ldb.DohvatiDataSet.Tables[tableName].Columns[i].DefaultValue; if(!this.cbImena.SelectedItem.ToString().Equals("<SVE OSOBE>")) dr["Osoba"] = this.cbImena.SelectedItem.ToString(); if(!this.cbProjekt.SelectedItem.ToString().Equals("<SVE PROJEKTE>")) dr["KratProjekt"] = this.cbProjekt.SelectedItem.ToString(); if(!this.cbVrstePosla.SelectedItem.ToString().Equals("<SVE VRSTE POSLA>")) dr["KratPosao"] = this.cbVrstePosla.SelectedItem.ToString(); if(this.checkBox1.Checked) dr["DatPosao"] = this.dtp.Value.ToString(); dr.EndEdit(); this.ldb.DohvatiDataSet.Tables[tableName].Rows.Add(dr); this.mSave_Click(this, System.EventArgs.Empty); // defined at the bottom of this method this.ldb.DohvatiDataSet.Tables[tableName].DefaultView.Sort = ""; this.dataGrid1.CurrentRowIndex = this.ldb.DohvatiDataSet.Tables[tableName].DefaultView.Count - 1; this.dataGrid1.ScrollToLeft(); } catch(System.Data.DBConcurrencyException dbce) { MessageBox.Show(dbce.Message.ToString(), "Error", MessageBoxButtons.OK, MessageBoxIcon.Exclamation, MessageBoxDefaultButton.Button1); } } private void mSave_Click(object sender, System.EventArgs e) { try { Cursor.Current = Cursors.WaitCursor; ((SqlCeDataAdapter)(this.ldb.GetAdapterList[this.ldb.GetTableIndex(tableName )])).Update(this.ldb.DohvatiDataSet.Tables[tableName].Select(null, null, DataViewRowState.Deleted)); ((SqlCeDataAdapter)(this.ldb.GetAdapterList[this.ldb.GetTableIndex(tableName )])).Update(this.ldb.DohvatiDataSet.Tables[tableName].Select(null, null, DataViewRowState.ModifiedCurrent)); ((SqlCeDataAdapter)(this.ldb.GetAdapterList[this.ldb.GetTableIndex(tableName )])).Update(this.ldb.DohvatiDataSet.Tables[tableName].Select(null, null, DataViewRowState.Added)); this.ldb.DohvatiDataSet.AcceptChanges(); this.dataGrid1.Focus(); Cursor.Current = Cursors.Default; this.UpdateAgreg(); } catch(System.Data.DBConcurrencyException dbce) { if(Cursor.Current == Cursors.WaitCursor) Cursor.Current = Cursors.Default; MessageBox.Show(dbce.Message.ToString(), "Error", MessageBoxButtons.OK, MessageBoxIcon.Exclamation, MessageBoxDefaultButton.Button1); } } I only get a concurrency violation when I insert a new row and change data in it, that save it. If no new rows are inserted I don't get a concurrency violation. Please help! Vladimir O¾ura! Tag: When trying to visually design... Tag: 102449

    - configuration issue I already have Visual Studio 2003 and have created PPC apps. Now, I need to create a Pocket PC program for a PPC with a 640x480 screen. So I downloaded the Pocket PC 2003 SDK and the 2003 SE Emulator images, and installed both. But when I create an app and try to view it in the VGA emulator, it says my program has been created for an older version of the PPC and will not display correctly, and it does not. I see only 1/4 of the 640x480 form (although the emulator does allow me to scroll around the full form). So my basic question is, "Is it posssbile to create an app with a 640X480 screen that will display properly, using VS 2003, the PPC 2003 SDK, and the 2003 SE emulator??? If so, any suggestions on what I might have done wrong in setting this all up????? THANKS! Tag: When trying to visually design... Tag: 102446

    - Connecting to SQL server 2000 from a Smart Device with VB.net 2003 I am new to mobile development, and I am having trouble figureing out how to connect to my SQL server. I use adodb in all of my desktop apps, but I can't find it's equivalent for a smart device app. I have data.sqlclient referranced, but no luck building a working connection string for it though. I do not want to use server ce or replication, because the devices that are going to be using the app are never going to leave the facility, and will always have a wireless connection to the server. Anyone got any advice on the best drivers to use, and how to connect? Thanks, Jerod Tag: When trying to visually design... Tag: 102445

    - bloody red phone button Hello all- Is there perhaps a way to change the default behavior of the red phone button (on PPC phone editions), or a way to detect when it is pressed if your app. isn't in focus?? The problem I'm having is that if my app. is being used, and a phone call comes in, you answer it, then after the call is done, you press the red phone button to end the call, it hides all other windows. It does this in any and every case, but it'd be much more useful to have the last application used be shown, instead of hiding everything. Is there a way to do this??? Thanks immensely, kurt Tag: When trying to visually design... Tag: 102434

    - icon for directory by shortcut Hello, I try to create an icon for a directory. The solution seams to be a shortcut in the directory name icon.lnk. I'm trying it by setting following values in the .INI file. In a "CEShortcuts" section with a line with a non cero type. e.g. "icon", 1, ... and now? With the hint to use a link of the DestinationDirs section I get a link to the directory, but not with an icon from my file xyz.dll with index -101. How can I realize my aim with a directory with my icon? I'm using Active Sync 4 an Windows mobile 5. Thanks in advance! John John Tag: When trying to visually design... Tag: 102432

    - Closing Thread Handle Hi, I have a question about closing a thread handle. I know I should close the thread handle after it terminates. Sometimes its a little hassle to check if a thread has terminated and then call CloseHandle(hThread); (... Yes, I know. I'm too lazy. :P ) I tried inserting CloseHandle(hThread); at the very end of the thread procedure. The program seems to be running fine this way. But I'm not so sure if this is would be 100% safe. Does anyone know if doing this is would have any ill effect? Thanks. BL Tag: When trying to visually design... Tag: 102424
