  • HQL to get elements that possess all items in a set

    - by Tauren
    Currently, I have an HQL query that returns all Members who possess ANY Award from a set of specified Awards: from Member m left join m.awards as a where a.name in ("Trophy","Ribbon"); What I now need is HQL that will return all Members who possess ALL Awards specified in the set of Awards. So, assuming this data: Joe has Trophy, Medal Sue has Trophy, Ribbon Tom has Trophy, Ribbon, Medal The query above would return Joe, Sue, and Tom because all three possess at least one of Trophy or Ribbon. But I need to return only Sue and Tom, because they are the only ones who possess all of the specified awards (Trophy and Ribbon). Here's the class structure (simplified): class Member { private String name; private Set<Award> awards; } class Award { private String name; }

  • Can I do video communication with silverlight 4.0?

    - by tom greene
    With silverlight 4.0, it is possible to show a live video of the user on the screen: Here is the code VideoBrush videoBrush = new VideoBrush(); CaptureSource captureSource = new CaptureSource { VideoCaptureDevice = CaptureDeviceConfiguration.GetAvailableVideoCaptureDevices().First() }; bool b = CaptureDeviceConfiguration.RequestDeviceAccess(); videoBrush.SetSource(captureSource); captureSource.Start(); myrect.Fill = videoBrush; However, I am looking at a way to show the video to someone else - seeing oneself on screen is not that interesting. Is it possible? Do I need my own server? Can I use clowd services to do the communication? Are there performance issues?

  • What is the best way to join/merge two tables by column cell matching in Excel?

    - by blunders
    I've found this excel add-in to buy that appears to do what I need, but I'd rather have code that's open to use as I wish. While a GUI is nice, it's not required. In an attempt to make the question more clear, I'm adding some two sample "input" tables in tab delimited form, and the resulting output table: SAMPLE_INPUT_TABLE_01 NAME<tab>Location John<tab>US Mike<tab>CN Tom<tab>CA Sue<tab>RU SAMPLE_INPUT_TABLE_02 NAME<tab>Age John<tab>18 Mike<tab>36 Tom<tab>54 Mary<tab>18 SAMPLE_OUTPUT_TABLE_02 NAME<tab>Age<Location> John<tab>18<tab>US Mike<tab>36<tab>CN Tom<tab>54<tab>CA Sue<tab>""<tab>RU Mary<tab>18<tab>"" If it matters, I'm using Office 2010 on Windows 7.

  • null-coalescing operator or conditional operator

    - by rkrauter
    Which coding style do you prefer: object o = new object(); //string s1 = o ?? "Tom"; // Cannot implicitly convert type 'object' to 'string' CS0266 string s3 = Convert.ToString(o ?? "Tom"); string s2 = (o != null) ? o.ToString() : "Tom"; s2 or s3? Is it possible to make it shorter? s1 does not obviously work.

  • PHP: form action on same page, still show same until refresh

    - by Karem
    Yes, Im having a little edit profile page, index.php?mode=profile. Lets take the username in the editprofile form as example. The username is already in the username-field. So i changed from "Peter" to "Tom" and press save. The action is ?mode=profile&edit=true. So now when i have pressed save it has updated the column in the db from Peter to Tom. But this field keeps having the value "Peter" until if i do press refresh (or f5), then "Tom" will appear. Like it hasnt updated in the database anything, although it did but it still shows Peter until next refresh.. like it caches, but it shouldnt cache nothing? Any help on this? Is it because its on the same "page" / file? what can i do

  • Returning several COUNT results from one ASP SQL statement

    - by user89691
    Say I have a table like this: Field1 Field2 Field3 Field4 fred tom fred harry tom tom dick harry harry and I want to determine what proportion of it has been completed for each field. I can execute: SELECT COUNT (Field1) WHERE (Field1 <> '') AS Field1Count SELECT COUNT (Field2) WHERE (Field2 <> '') AS Field2Count SELECT COUNT (Field3) WHERE (Field3 <> '') AS Field3Count SELECT COUNT (Field4) WHERE (Field4 <> '') AS Field4Count Is it possible to roll up these separate SQL statements into one that will return the 4 results in one hit? Is there any performance advantage to doing so (given that the number of columns and rows may be quite large in practice)?

  • Retrieve names by ratio of their occurance

    - by jjiffer
    Hello, I'm somewhat new to SQL queries, and I'm struggling with this particular problem. Let's say I have query that returns the following 3 records (kept to one column for simplicity): Tom Jack Tom And I want to have those results grouped by the name and also include the fraction (ratio) of the occurrence of that name out of the total records returned. So, the desired result would be (as two columns): Tom | 2/3 Jack | 1/3 How would I go about it? Determining the numerator is pretty easy (I can just use COUNT() and GROUP BY name), but I'm having trouble translating that into a ratio out of the total rows returned. Any help is much appreciated!

  • How can I write an installer for 32 and 64 bit

    - by tom greene
    I have a .NET app which works in 32 and 64 bit. I would like to write one single installer that installs to c:\program files, not c:\program files(x86) regardless of the platform. From this link: http://msdn.microsoft.com/en-us/library/w1behyzx(v=VS.90).aspx it doesn't look possible. Is it the case?

  • Configure Postfix to send/relay emails Gmail (smtp.gmail.com) via port 587

    - by tom smith
    Hi. Using Centos 5.4, with Postfix. I can do a mail [email protected] subject: blah test . Cc: and the msg gets sent to gmail, but it resides in the spam folder, which is to be expected. My goal is to be able to generate email msgs, and to have them appear in the regular Inbox! As I understand Postfix/Gmail, it's possible to configure Postfix to send/relay mail via the authenticated/valid user using port 587, which would no longer have the mail be seen as spam. I've tried a number of parameters based on different sites/articles from the 'net, with no luck. Some of the articles, actually seem to conflict with other articles! I've also looked over the stacflow postings on this, but i'm still missing something... Also talked to a few people on IRC (Centos/Postfix) and still have questions.. So, i'm turning to Serverfault, once again! If there's someone who's managed to accomplish this, would you mind posting your main.cf, sasl-passwd, and any other conf files that you use to get this working! If I can review your config files, I can hopefully see where I've screwed up, and figure out how to correct the issue. Thanks for reading this, and any help/pointers you provide! ps, If there is a stackflow posting that speaks to this that I may have missed, feel free to point it out to me! -tom

  • Drobo FS vs. MacBook Pro: Finder works, Drobo Dashboard doesn't

    - by dash-tom-bang
    Does anyone have any experience with the new Drobo FS, specifically using it from a MacBook Pro? My experience thus far is this: Set up the Drobo Dashboard software (hereinafter called simply 'Dashboard') on my WinXP machine, which is hard-wired to the network to do the data migration from my NAS-that's-being-replaced (a 250G SimpleShare which works well enough but I was always afraid of losing the one disk). The Dashboard seems to work ok, except that the DroboCopy function doesn't work at all. This is the backup solution, which I can configure, and if I launch it (e.g. to back up from the old NAS to the Drobo) it spins the NAS, seeking the drive all over hell and creation, until finally giving up an hour+ later with zero files copied. Selecting only a subset of the data yields the same effect albeit more quickly. On my Mac I installed the Dashboard software too, since most of my fiddling with the device will be from my couch in the living room. Finder connects to the box just fine, fwiw, but Dashboard just sits there, "waiting for connection." This is considerably more bothersome than the above paragraph, but I figured I'd give whatever information I have. Drobo is insisting that I send them this "Debug Log" file that their software generates. Does anyone know what's in it? It's encrypted and they won't tell me, which spooks me just a bit; not like I'm terribly concerned about privacy but I don't want to be sending personal information out to every clown who says they "need" it in order to help me. thanks a ton, -tom!

  • Windows RDP cannot connect to x64 server from XP SP3+ [closed]

    - by Tom
    Hi all, I have a strange problem that I can't seem to find the answer to anywhere online. The issue has to do with using Windows RDP to connect to our servers. Here is what works: -XP/Vista client (any SPs) connecting to 32-bit Server 2003 machine -XP (SP2 and lower) client conecting to 64-bit Server 2003 machine Here is what does not work: - XP SP3+/Vista client connecting to 64-bit Server 2003 machine It appears that the issue is that XP SP3 and Vista clients cannot connect to x64 Server 2003 boxes. After entering the username/password, we get an error message saying the below, and the connection drops: To log on to this remote computer, you must have Terminal Server User Access persmissions on this computer. By default, members of the Remote Desktop Users group have these permissions. If you are not a member of the Remote Desktop Users group or another group that has these persmissions, or if the Remote Desktop User group does not have these permissions, you must be granted these permissions manually. The issue is that the user is a member of the Administrators group, which has permission. Also, logging in using the same username, but from an XP SP2 machine, has no problems at all. I hope I explained this well enough, and any help/insight that can be given would be greatly appreciated. Thanks, Tom

  • Import exponetial fixed width format data into Excel

    - by Tom Daniel
    I've received a bunch of text data files consiting of Lots of records (30K/file) of 3 fields each of 5-place numbers in exponential format: s0.nnnnnEsee (where s is +/-, n is a digit and ee is the exponent (always 2 digit). When I open the file in Notepad, the format is perfectly uniform throughout each file, but when I import it to Excel using Data|Import|Fixed Width, many of the data values get messed up, no matter what format (text, exponential, various custom tries) I assign to the cells. Looking at the Notepad version, it appears that leading + signs were replaced with a space in the data file, but the sign of the exponential is always there. This means that some fields begin with a space, and this appears to confuse the Excel import routine. I get the same result in Excel 2003 and 2007. I'm sure there's a straightforward solution (hopefully without a messy VBA routine), but I can't figure out what to try next. :-) To clarify (hopefully), here are some input records and the corresponding text input to Excel: Notepad Excel -0.11311E+01 0.10431E-04 0.27018E-03 -0.11311E 1.0431E-05 2.7018E-04 0.19608E+00-0.81414E-02-0.89553E-02 0.19608E -8.1414E-03 8.9553E-03 etc. Whoopee! Solved my own problem - in the spirit of Jeopardy, now that I've begun the question, here's the answer - Use a different "File Origin" - several other than the default "Unicode UTF..." work fine! What a pain. Hope this helps somebody else avoid a few unpleasant hours! Aloha from Kona, Tom

  • vmware - ACE, Workstation - how to manage remoe clients??

    - by tom smith
    Hi. Exploring Vmware products/services and have a few questions. As I understand VM, you can use VMWare Workstation to create a VM of a target machine/box/OS. Let's call this VM, "foo". If I have 100 client PCs in my dept, and I want to install the VM (foo) on each client, and also manage the remote VM instances of (foo). How can I accompish this? Let's assume that the client machines are running Windows7, and have the vmplayer app installed on the box. I'm looking to do the following kinds of actions regarding the remote client machines: -Update the foo VM/image with new updated copies -Make sure that every VM "foo" has the same user, but a unique passwd -Monitor the traffic/status of each client VM "foo" oin each client -Start/Stop each client VN "foo" from the master console -Etc... Can this be accomplished? How would I do it, what services/products would I need? I've tried toalking to a few of the pre-sales guys in VMWare, and got nowhere, other than telling me to email my questions!! Looking at google shed more insight, but I still have questions. So, if you have detailed VMWare understanding, pointers to consultants, or resellers who can help, all pointers are greatly appreciated. Thanks -tom

  • Workaround for datadude deployment bug - NullReferenceException

    - by jamiet
    I have come across a bug in Visual Studio 2010 Database Projects (aka datadude aka DPro aka Visual Studio Database Development Tools aka Visual Studio Team Edition for Database Professionals aka Juneau aka SQL Server Data Tools) that other people may encounter so, for the purposes of googling, I'm writing this blog post about it. Through my own googling I discovered that a Connect bug had already been raised about it (VS2010 Database project deploy - “SqlDeployTask” task failed unexpectedly, NullReferenceException), and coincidentally enough it was raised by my former colleague Tom Hunter (whom I have mentioned here before as the superhuman Tom Hunter) although it has not (at this time) received a reply from Microsoft. Tom provided a repro, namely that this syntactically valid function definition: CREATE FUNCTION [dbo].[Function1]()RETURNS TABLEASRETURN (    WITH cte AS (    SELECT 1 AS [c1]    FROM [$(Database3)].[dbo].[Table1]   )   SELECT 1 AS [c1]   FROM cte) would produce this nasty unhelpful error upon deployment: C:\Program Files

circumstances that need to be met for this error to occur: The object being deployed is an inline function  (may also exist for multistatement and scalar functions - I haven't tested that) That object includes SQLCMD variable references The object has already been deployed successfully Just to reiterate that last bullet point, the error does not occur when you deploy the function for the first time, only on the subsequent deployment.   Luckily I have a direct line into a guy on the development team so I fired off an email on Friday evening and today (Monday) I received a reply back telling me that there is a simple fix, one simply has to remove the parentheses that wrap the SQL statement. So, in the case of Tom's repro, the function definition simpy has to be changed to: CREATE FUNCTION [dbo].[Function1]()RETURNS TABLEASRETURN --(    WITH cte AS (    SELECT 1 AS [c1]    FROM [$(Database3)].[dbo].[Table1]   )   SELECT 1 AS [c1]   FROM cte--) I have commented out the offending parentheses rather than removing them just to emphasize the point. Thereafter the function will deploy fine. I tested this out on my own project this morning and can confirm that this fix does indeed work.   I have been told that the bug CAN be reproduced in the Release Candidate (RC) 0 build of SQL Server Data Tools in SQL Server 2010 so am hoping that a fix makes it in for the Release-To-Manufacturing (RTM) build. Hope this helps @jamiet

  • The Grand Unified Framework Theory

    Tom Janssens left a comment: What still bugs me is that we do not have a unified pattern for all .net dev (using modelbinders and icommand for example...) But, Tom we are pretty close. At least as close as we should be, I think. With .NET there are plenty of low level patterns we can reuse regardless of the application platform or architecture. Stuff like: Asynchronous programming with events or the TPL. Object queries with LINQ. Resource management with IDispose. At a higher...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.
