• MikePHall SQL mobile 2005

  Hi There, I'm currently writing an application for a windows mobile 5 device which will store data in sql mobile 2005. I would like to know which would be the most efficient way of writing the following example to work with the above. (up until now all the code i have written has been in vb6 and connecting to an access database) Set db = DBEngine.OpenDatabase("location\database.mdb") ' strSQL = "SELECT * FROM Floats WHERE AgentName = '" & lblAgentName.Caption & "' AND Status = 0 " ' Set rs3 = db.OpenRecordset(strSQL) If rs3.RecordCount > 0 Then rs3.MoveLast lngRecordCount3 = rs3.RecordCount rs3.MoveFirst Else lngRecordCount3 = 0 End If ' If lngRecordCoun ...Show All

• clint 2 How to drop database table if it exits in sql mobile version?

  Hi, am using VB.net and Visual Studio 2005 to compile a program for a Pocket PC with MicrosoftR Windows Mobile 2003 Second Edition. I am using sql mobile also. How to drop database table if it exits in sql mobile version Thanks a lot. Just issue a SQL query with a DROP TABLE command. See http://msdn2.microsoft.com/en-us/library/ms173418.aspx First do a query which uses the COUNT command. If that query succeeds you know that the table exists and then you can do a drop query. You can't do this in one query, because SQL Mobile does not support multiple queries in one command. Hi, Thanks for your reply, and in fact I know your solution, but if the database table does not exist a ...Show All

• Julianín Finding distances

  Hey, Could someone point me to documentation on how to find distance between to locations via their lat/long or another way to do what i'm trying to do I have a list of locations and their latitude/longitude and I want to display a map that zooms out to display a minimum of 10 locations near a location that is typed in.

• knormann VS .NET to VS.NET 2005

  I have a problem with the conversion of dates after migrate of VS.NET 2003 to VS.NEt 2005 Test: Dim oDate As DateTime = DateTime.Parse(oDst.Tables(0).Rows(1).Item("mydate").ToString()) Error: invalidcastexception ..... In my project of vs.net 2003 worked well that code I sorry for my inlges ... i speak spanish Thanks. It seems that the date format you were using before is nolonger supported by the normal "Parse" method. If the format is consistent, you can probably get it to work using ParseExact. If you can determine the exact date format that was supported in 2003 but is not supported in 2005, you may consider filing it as a bug to be fixed in the next version. -Ryan / Kardax ...Show All

• Hussain Saffar compact framework v2 sp1 installation problem

  I have been using vs2005 and cf v2 to develop an application. I recently installed the cf v2 sp1 redistributable thinking that it would tie into the vs ide but it did not. A few days later I found the cf v2 sp1 patch for vs 2005 and tried to install it but get an error message. I have uninstalled the cf and tried installing the patch by itself and get the same error. I reinstalled the cf v2 sp1 redistributable and tried the patch and get the same error. Here is the error: "The upgrade patch cannot be installed by the Windows Installer service because the program to be upgraded may be missing, or the upgrade patch may update a different version of the program.

• Shawnmcf V4 3D issues with get map view

  Just getting ye old clusting working with V4 and discovered if you zoom out below about 6 the topleft and bottomright values aren't exactly what you expect. For example if you go to the sdk example zoom right out so you can see half the world you get: top left: 14.0318893599231, -1.14591559026165 top right: 14.0318893599231, 1.14591559026165 bottom left: 15.1778049501847, -1.14591559026165 bottom right: 15.1778049501847, 1.14591559026165 Which is not very helpful.... I can sort of see what is happening as we are round we don't quite have a corners... I would have perferred is a full range representing that half the world is visible. I'll see if a can make a fix based on altitude and the centre point... John. We ...Show All

• KervyChoa problems with VS2005 and IE7

  Hi, if running VS2005 with IE7 (the beta, the final or the WinVista RC1 included one) it is not possible to create a new C++ "Smart Device" project. If I choose to create a "Win32 Smart Device Project" with Visual C++, enter a name for the project in the "New Project" dialog i'll get the "blub" sound, wich also appears if internet explorer blocks a pop up or an addon, and Visual Studio falls back to the "New Project" dialog instead of showing the details for creating the new application. i guess this has something to do with the internet explorer security settings and so I tried to disable them all or setting them to the lowest possible level... has anybody an idea how to get VS ...Show All

• TIENG Sunheng [Vista] + Device Emulator + Mobile Device Center

  Hello, I have just migrated to Windows Vista. Everything is working (for now :-) ), I only have some problems with cradling VS 2005 Pocket PC Device Emulator. (to be more specific, i would like to share Internet between my computer and my Virtual Pocket PC.) I learned, that Active Sync was changed with Windows Mobile Device Center and that the WMDC should install via Windows Update (i run everything and checked in control panel, but WMDC was not there). Next information I received was the following one: Your Windows Mobile device must be connected to the computer for Windows Update to be able to detect the driver update and install the update. The problem is, that I don't have a physical device, I am o ...Show All

• hypo Display a map showing multiple route points.

  I know that this can be done using yahoo.maps/beta but not yet with Microsoft Virtual Earth…. I have a requirement to display a map that shows the route between a number of points (possibly up to 20) but normally just 8. I will provide to the API the best optimized route around the points – but the API only allows for a driving route between two points. And this would mean printing off maps that show A to B, B to C, C to D etc. Any suggestion if / when this feature will be implemented Also I don’t want to go down the web service route as this is cost prohibitive. Thanks in advance for any suggestions…. Surely it would be easy enough to plot them yourselves There will be q ...Show All

  Hi, Im trying to make a program to communicate with something that is connected with the serial port. The device i wanna connect to the serial port knows several commands. So basically there needs to be a simple connection with the port so that i can put commands in the console and the device reply's me and sets its output on the console. So far i got this: static SerialPort serialPort; public static void Main() { serialPort = new SerialPort("COM1", 19200, Parity.None, 8, StopBits.One); } I hope someone could help me a bit.
