    - by kawtousse
    Goal: Parse a string from an input type text into TIME type to be inserted in MYSQL Database. String start= request.getParameter("startp"); System.out.println("start:" +start); SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss"); long ms=0; try { ms = sdf.parse(start).getTime(); System.out.println(" the value of ms is:" +ms); } catch (ParseException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } Time ts = new Time(ms); System.out.println("the value of ts is:" +ts); start:14:12 (value witch i entered actually in the form at the start field named startp) the value of ts is :01:00:00 java.text.ParseException: Unparseable date: "14:12" at java.text.DateFormat.parse(Unknown Source) ms not displayed I ensure that database type of the following parameter is TIME.

  • C# Image.Clone to byte[] causes EDIT.COM to open on Windows XP

    - by JayDial
    It appears that cloning a Image and converting it to a byte array is causing EDIT.COM to open up on Windows XP machines. This does not happen on a Windows 7 machine. The application is a C# .NET 2.0 application. Does anyone have any idea why this may be happening? Here is my Image conversion code: public static byte[] CovertImageToByteArray(Image imageToConvert) { imageToConvert.Clone() as Image; if(clone == null) return null; imageToConvert.Dispose(); byte[] imageByteArray; using (MemoryStream ms = new MemoryStream()) { clone.Save(ms, clone.RawFormat); imageByteArray = ms.ToArray(); } return imageByteArray; } public static Image ConvertByteArrayToImage(byte[] imageByteArray, ImageFormat formatOfImage) { Image image; using ( MemoryStream ms = new MemoryStream(imageByteArray, 0, imageByteArray.Length)) { ms.Write(imageByteArray, 0, imageByteArray.Length); image = Image.FromStream(ms, true); } return image; } Thanks Justin

  • ExceptionHandling with Spring 3

    - by mjf
    I have this controller: @RequestMapping(value = "*.xls", method = RequestMethod.GET) public String excel(Model model) { return "excel"; The excel wiew opens actually a ExcelViewer, which is build in method protected void buildExcelDocument(Map<String, Object> map, WritableWorkbook ww, HttpServletRequest hsr, HttpServletResponse hsr1) throws Exception { Class.writecontent Class.writeMoreContent Called methods write content to the Excel sheet and they can throw e.g biffException. How can I show a certain error page when Exception is occured? I tried this @Controller public class ExcelController { @ExceptionHandler(BiffException.class) public String handleException(BiffException ex) { return "fail"; } @RequestMapping(value = "*.xls", method = RequestMethod.GET) public String excel(Model model) { return "excel"; } } But I'm getting the server's error message about Exceptions. Maybe a bean definition missing?

  • Calling this[int index] via reflection

    - by tkutter
    I try to implement a reflection-based late-bound library to Microsoft Office. The properties and methods of the Offce COM objects are called the following way: Type type = Type.GetTypeFromProgID("Word.Application"); object comObject = Activator.CreateInstance(type); type.InvokeMember(<METHOD NAME>, <BINDING FLAGS>, null, comObject, new object[] { <PARAMS>}); InvokeMember is the only possible way because Type.GetMethod / GetProperty works improperly with the COM objects. Methods and properties can be called using InvokeMember but now I have to solve the following problem: Method in the office-interop wrapper: Excel.Workbooks wb = excel.Workbooks; Excel.Workbook firstWb = wb[0]; respectively foreach(Excel.Workbook w in excel.Workbooks) // doSmth. How can I call the this[int index] operator of Excel.Workbooks via reflection?

  • MS Chart with ASP.NET chart type "column" not showing axis x label if there are more than 9 bar in t

    - by Bayonian
    Hi, I'm having problem with MS Chart chart type column. If there are only 9 bar in the chart like the following picture, then the axis-x label show up properly. However, there are more than 9 bars bar the chart, the axis-x label wont show up properly, some of them just dissappear. Here's my mark-up for the chart: <asp:Chart ID="chtNBAChampionships" runat="server"> <Series> <asp:Series Name="Championships" YValueType="Int32" Palette="Berry" ChartType="Column" ChartArea="MainChartArea" IsValueShownAsLabel="true"> <Points> <asp:DataPoint AxisLabel="Celtics" YValues="17" /> <asp:DataPoint AxisLabel="Lakers" YValues="15" /> <asp:DataPoint AxisLabel="Bulls" YValues="6" /> <asp:DataPoint AxisLabel="Spurs" YValues="4" /> <asp:DataPoint AxisLabel="76ers" YValues="3" /> <asp:DataPoint AxisLabel="Pistons" YValues="3" /> <asp:DataPoint AxisLabel="Warriors" YValues="3" /> <asp:DataPoint AxisLabel="Mara" YValues="4" /> <asp:DataPoint AxisLabel="Saza" YValues="9" /> <asp:DataPoint AxisLabel="Buha" YValues="6" /> </Points> </asp:Series> </Series> <ChartAreas> <asp:ChartArea Name="MainChartArea"> </asp:ChartArea> </ChartAreas> </asp:Chart> I don't know it works with only 9 bars? Is there any way to make the chart work properly? Also, if possible, how to make each bar have different color. Thank you.

  • What MS technology to use for HTTP service returning XML?

    - by Borek
    I need to create a service that: accepts HTTP requests (with query string or HTTP POST parameters) does some processing on the requests (checking if the request is valid, authentication etc.) reads data from a custom store (another HTTP call in our case) returns the result as custom XML (defined with XSD) I'm trying to think of various MS technologies that could help me and how good they would be for this scenario (pretty standard one I guess). The tasks above are relatively separate, this is what comes to mind: HTTP front-end: ASP.NET Web Forms ASP.NET MVC (seems more appropriate here as I won't need server controls, view state etc.) WCF? Don't know much about it or how well it would suit my task. Custom logic on the server: this will probably be a generic C# code in all cases (sometimes "plugged into" or called from MVC controllers or some equivalent place in other technologies) Reading data from internal data stores: As said, this is another HTTP server in our case. Options that come to mind: Just read the data using something like WebClient (Just theoretically) implement a LINQ provider (Just even more theoretically) implement an EF provider Output the data as custom XML: Linq2XML Serialization? Is it flexible enough? Does WCF provide some tools for this? Some "OXM" - Object/XML mapper if there is something like that for .NET I may be wrong in many of my assumptions, this is just a quick list that comes to mind after a quick research. Some general notes / questions: Testing is important Solution with a clear domain model would be much preferred over the one without Can Entity Framework actually help somewhere in my scenario? If so, where and how? Would WCF be an appropriate technology for this? I don't know much about it.

  • How to upload files and store them in a server local path when MS SQL SERVER allows remote connectio

    - by user193655
    I am developing a win32 windows application with Delphi and MS SQL Server. it works fine in LAN but I am trying to add the support for SQL Server remote connections (= working with a DB that can be accessed with an external IP, as described in this article: http://support.microsoft.com/default.aspx?scid=kb;EN-US;914277). Basically I have a Table in DB where I keep the DocumentID, the document description and the Document path (like \FILESERVER\MyApplicationDocuments\45.zip). Of course \FILESERVER is a local (LAN) path for the server but not for the client (as I am now trying to add the support for remote connections). So I need a way to access \FILESERVER even if of course I cannot see it in LAN. I found the following T-SQL code snippet that is perfect for the "download trick": SELECT BulkColumn as MyFile FROM OPENROWSET(BULK '\FILESERVER\MyApplicationDocuments\45.zip' , SINGLE_BLOB) AS X With the code above I can download a file on the client. But how to upload it? I need an "Uppload trick" to be able to insert new files, but also to delete or replace existing files. Can anyone suggest? If a trick is not available could you suggest an alternative? Like an extended stored procedure or calling some .net assembly from the server.

  • What problem did MS solve by creating PowerShell? [closed]

    - by Fred
    I'm asking because PowerShell confuses me. I've been trying to write some deployment scripts using PowerShell and I've been less than enthused by the result. I have a co-worker who loves PowerShell and defends it at every turn. Said co-worker claims PowerShell was never written to be a strong shell, but instead was written to: a) Allow you to peek and poke at .NET assemblies on the command-line (why is this a reason for PowerShell to exist?) b) To be hosted in .NET applications for automation, similar to DCOP in KDE and how Gnome is using CORBA. c) to be treated as ".NET script" rather than as an actual shell (related to b). I've always felt like Windows was missing a decent way to bang out automation scripts. cmd is too simplistic in many cases, and WSH is too obtuse (although the combination can be used successfully, I'm not a fan). When I first heard about PowerShell I felt like Windows was finally getting a decent shell that would be able to help with automation of many tasks, but recent experiences, and my co-worker, tell me otherwise. To be clear, I don't take issue with the fact that it's built on .NET, or that it passes objects around rather than text (despite my Unix background :]), and I'm not arguing that PowerShell is useless, but from what I can see, it doesn't solve the problem I was hoping it would solve very well. As soon as you step outside of the .NET/Powershell world, things quit being nice and cozy for you. So with all that out of the way, what problem did MS solve by creating PowerShell, or is it some political bastard child as I suspect? I've googled and haven't hit upon anything that sufficiently answered that for me, but the more citations the better.

  • How to write to a Text File in Pipe delimited format from MS Sql Server / ASP.Net?

    - by NJTechGuy
    I have a text file which needs to be constantly updated (regular intervals). All I want is the syntax and possibly some code that outputs data from a MS Sql Database using ASP.Net. The code I have so far is : <%@ Import Namespace="System.IO" %> <script language="vb" runat="server"> sub Page_Load(sender as Object, e as EventArgs) Dim FILENAME as String = Server.MapPath("Output.txt") Dim objStreamWriter as StreamWriter ' If Len(Dir$(FILENAME)) > 0 Then Kill(FILENAME) objStreamWriter = File.AppendText(FILENAME) objStreamWriter.WriteLine("A user viewed this demo at: " & DateTime.Now.ToString()) objStreamWriter.Close() Dim objStreamReader as StreamReader objStreamReader = File.OpenText(FILENAME) Dim contents as String = objStreamReader.ReadToEnd() lblNicerOutput.Text = contents.Replace(vbCrLf, "<br>") objStreamReader.Close() end sub </script> <asp:label runat="server" id="lblNicerOutput" Font-Name="Verdana" /> With PHP, it is a breeze, but with .Net I have no clue. If you could help me with the database connectivity and how to write the data in pipe delimited format to an Output.txt file, that had be awesome. Thanks guys!

  • MS Exam 70-536 - How to throw and handle exception from thread?

    - by Max Gontar
    Hello! In MS Exam 70-536 .Net Foundation, Chapter 7 "Threading" in Lesson 1 Creating Threads there is a text: Be aware that because the WorkWithParameter method takes an object, Thread.Start could be called with any object instead of the string it expects. Being careful in choosing your starting method for a thread to deal with unknown types is crucial to good threading code. Instead of blindly casting the method parameter into our string, it is a better practice to test the type of the object, as shown in the following example: ' VB Dim info As String = o as String If info Is Nothing Then Throw InvalidProgramException("Parameter for thread must be a string") End If // C# string info = o as string; if (info == null) { throw InvalidProgramException("Parameter for thread must be a string"); } So, I've tried this but exception is not handled properly (no console exception entry, program is terminated), what is wrong with my code (below)? class Program { static void Main(string[] args) { Thread thread = new Thread(SomeWork); try { thread.Start(null); thread.Join(); } catch (InvalidProgramException ex) { Console.WriteLine(ex.Message); } finally { Console.ReadKey(); } } private static void SomeWork(Object o) { String value = (String)o; if (value == null) { throw new InvalidProgramException("Parameter for "+ "thread must be a string"); } } } Thanks for your time!

  • In C/C++,how to link dynamic link lib which compiled in GCC/G++ in MS VStudio?

    - by coanor
    These days, I use Flex & Bison generated some codes to develop a SQL-parser alike tools, these code can't compiled silently(may be this another topic) in VS2005,but GCC/G++ works well, then I compiled these code with mingw in dll(in windows xp), and then linked these function facades in VS2005, but it seems can't link the dll during linking. Does MS VS2005 recognize the dll which compiled using mingw on windows? Is there anything I need to do additional? For example, adding something in the include-file that declare the exported APIs? Does any one can give some advices? The condition is, as in VS2005, if you want to export some APIs, you may show a *.def file to tell nmake which API you want to export, and then you may create a(or some) *.h file to declare somthing about these APIs(adding some stdcall alike prefix as a call protocal) and some data-type definition. But with GCC/G++, you do not need to do such boring things, just use [ar], you can get these APIs, so my *.h file do not add call protocol and no *.def, just like common function declaration. After *.dll generated, add the *.h file and [mv] generated *.dll in VS2005 project directory, then set the linking *.dll in project setting. Does these steps generated my Question? BTW, I found and tested VC6-compiled dll can be linked with mingw in Windows XP, but the reverse can't work. Anyway, forgive my poor English, and thanks for your concern.

  • How to use an excel data-set for a multi-line ggplot in R?

    - by user1299887
    I have a data set in excel that I am trying to create a multiple line plot with on R. The data set contains 7 food groups and the calories consumed daily associated to the groups. As well, there is that set of data over 38 years (from 1970-2008) and I am attempting to use this data set to create a multiple line plot on R. I have tried for hours on end but can not seem to get R to recognize the variables within the data set.

  • Workstations cannot see new MS Server 2008 domain, but can access DHCP.

    - by Radix
    The XP Pro workstations do not see the new replacement domain upon boot; they only see their cached entry for the old (server 2003) domain controller. The old_server is not connected to the network. I have DHCP working with the same scope as the old_server. In my "before-asking" search for a solution I came across the following two articles, and I recall doing things as suggested by the articles. http://www.windowsreference.com/windows-server-2008/how-to-setup-dhcp-server-in-windows-server-2008-step-by-step-guide/ http://www.windowsreference.com/windows-server-2008/step-by-step-guide-for-windows-server-2008-domain-controller-and-dns-server-setup/ The only possible issue is: I was under the impression that the domain netbios needed to match the DC's netbios. The DC netbios is city01 while the domain's FQDN is city.domain.org (I think this is mistaken and should have been just domain.org) But, the second link led me to a post which I believe answers my question. I did as they instructed by opening Local Area Connection Properties, then selecting TCP/IPv4 and setting the sole preferred DNS server to the local hosts static IP (10.10.1.1). Search for "Your problems should clear up" for the post I'm referencing: http://forums.techarena.in/active-directory/1032797.htm Have I misunderstood their instructions? I am hoping to reach the point where I can define users and user groups. Also, does TechNet have a single theoretical overview document I could read. I really don't like treating comps as magic. I will be watching this closely and will quickly answer any questions. If I've left anything out it is because I did not know it was needed. PS: I am loath to ask obviously basic questions, but I am tired and wish to fix this before tomorrow. Also, this is my first server installation, thank you for your help.

  • New keyboard for linux: Adesso Tru-Form or MS Natural Keyboard 4000?

    - by Andrea
    Hi folks! I'm going to buy a new ergonomic keyboard for my laptop. In the following, keep in mind I live in Italy. I considered the following models: Adesso PCK-308UB - Adesso Tru-Form™ Pro - Contoured Ergonomic Keyboard with TouchPad-PS2 Pro: has a built-in touchpad in the same position of my laptop somewhat cheaper than the alternative below Cons: the surface doesn't seem to be bowl-shaped. keys seem to lay on a straight slightly-inclined surface. It seems an idea used extensively in other ergonomic keyboards according to a few comments on the net, new Adesso keyboards seem to lack robustness, they're likely to loose small parts after a few weeks or months. Other users, instead, seem to never had any problem in years and swear by their quality and comfortability. Those who had problems, however, lamented a lack of responsiveness from the manufacturer. I'm not sure whether the keyboard, at least the standard keys, and the touchpad will both be recognized correctly under linux distros (I mostly use FC btw) last time I checked, Adesso didn't have local resellers in my country Microsoft Natural Ergonomic Keyboard Pro: recognized as one of the most comfortable keyboards reliable customer service operating in my country AFAIK there are several documented ways to get extra buttons work with linux Cons: it doesn't have a builtin touchpad and has a numeric keypad wasting space to reach mouse But there could be other keyboards I haven't considered yet, so here follows my ideal keyboard wishlist, ordered by priority linux compatible basic ergonomic design, which entails split tilted keyboard and pads advanced ergonomic design, like true-ergonomic's or kinesis , where special keys (like enter, caps-lock...) are placed symmetrically in the middle to be used by thumbs a builtin touchpad/trackball placed under the keyboard. I just love this on my notebook. I think it's pretty effective, since it allows my hand to rest naturally everytime I use it. Any opinion on this? high-quality switches, like cherry's (unsure about this one) additional programmable keys placed near usual ones, to simplify typing shortcuts TIA Andrea

  • Is the master database backup crucial for restoring MS SQL server in the event where you have to res

    - by Imagineer
    I have been advise by Commvault partner support to turn off the backup of the master database as the backup failed due to the log file being lock. The following is the advise given: "The message is caused by Commvault’s inability to backup the master database’s transaction log. If this is happening intermittently its possible that something is locking the transaction log, preventing SQL iData agent from accessing the log. Typically the master database is just a template and is not used by any applications (applications that do require the use of an SQL database create their own) so there should be no harm in preventing it from being backed up You can do this by nominating NOT to back it up in the primary copy for the SQL data agent" The following is the error that I get. sqlxx SQL Server/ SQLxx N/A/ System DBs 19856* (CWE) Transaction Log N/A 01/08/2010 19:00:16 (01/08/2010 19:00:18 ) 01/08/2010 19:03:15 (01/08/2010 19:03:14 ) 1.44 MB 0:01:11 0.071 2 0 1 ITD014L2 Failure Reason: • ERROR CODE [30:325]: Error encountered during backup.
