  • Using sql column names in hibernate createSQlquery result

    - by Ricardo
    Hi all, i have a couple of sql views with composite primary keys that i want to query, and since Hibernate makes it a pain to work with composite keyes, im using createSQLQuery. The problem is that this method can only return a List, and i need to refer to the colums by their index. Any chance i could do like jdbc and refer to the columns by their sql name insted of their index? thanks

  • Using two ports on my ZyXel USG gateway to patch two devices together?

    - by Matthew Beza
    I don't know if this is possible but it would save me many long drives! I have drawn, with my epic MS Paint skills, my current setup. I have a ZyXel USG300 Gateway with a built in 5 port switch. It supports bridging, tunnles, VLANs, etc.. I have a Cisco WLC2112 plugged into port 6 (P6). The cisco is set to 192.168.6.2 and P6 is set to 192.168.6.1. This works but I need to incorporate a Nomadix AG3000 to handle guests. (Router (A) in the picture). So I need the Cisco WLC2112 to use the Nomadix as if it where plugged into it's LAN port. Right now the Nomadix WAN Port is plugged into (P2) on the ZyXel, and the Nomadix LAN port is plugged into (P3). Is it possible to set something up where (P3) and (P6) are somehow "Patched" as if the Cisco was plugged directly into the Nomadix LAN port? Basically making the ZyXel a fancy Cat5e coupler?

  • MATLAB: Convert two array to a sparse matrix

    - by CziX
    I'm looking for an a command or trick to convert two arrays to a sparse matrix. The two arrays contain x-values and y-values, which gives a coordinate in the cartesian coordinate system. I want to group the coordinates, which if the value is between some value on the x-axes and the y-axes. % MATLAB x_i = find(x > 0.1 & x < 0.9); y_i = find(y > 0.4 & y < 0.8); %Then I want to find indicies which are located in both x_i and y_i Is there an easy way to this little trick?

  • Incorrect rendering in dojox charting stacked column?

    - by FokeyJoe
    Hiya, I seem to be having a problem with my dojo stackedcolumn whereby the scale of some of the bars is correct for some x-axis points, but not others. Here's my code (observe the northern ireland hydro should be 70, but only shows as around 30): dojo.addOnLoad(function() { var chart1 = new dojox.charting.Chart2D("sitesbycountry"); chart1.addPlot("default", {type: "StackedColumns", gap: 10}); chart1.addPlot("horzgrid", {type: "Grid", hMajorLines: true, vMajorLines: false}); chart1.addAxis("x", {labels: [{value: 1, text: 'Northern Ireland'}, {value: 2, text: 'Wales'}, {value: 3, text: 'Scotland'}, {value: 4, text: 'England'}], minorTicks: false, microTicks: false}); chart1.addAxis("y", {vertical: true, minorTicks: false, microTicks: false}); chart1.addSeries("Hydro", [70, 53, 198, 102], {fill: "#ddddff"}); chart1.addSeries("Wind and Wave", [67, 51, 150, 245], {fill: "#FEFFBF"}); chart1.addSeries("Landfill", [1, 23, 40, 0], {fill: "#CFFFD1"}); chart1.addSeries("Other Biofuels and Wastes", [4, 3, 11, 66], {fill: "#DFD2C3"}); chart1.render(); }); Is this a behaviour of the chart that I'm not aware of? TIA FokeyJoe

  • Two-state script monitor not auto-resolving in SCOM

    - by DeliriumTremens
    This script runs, and if it returns 'erro' an alert is generated in SCOM. The alert is set to resolve when the monitor returns to healthy state. I have tested the script with cscript and it returns the correct values in each state. I'm baffled as to why it generates an alert on 'erro' but will not auto-resolve on 'ok': Option Explicit On Error Resume Next Dim objFSO Dim TargetFile Dim objFile Dim oAPI, oBag Dim StateDataType Dim FileSize Set oAPI = CreateObject("MOM.ScriptAPI") Set oBag = oAPI.CreatePropertyBag() TargetFile = "\\server\share\file.zip" Set objFSO = CreateObject("scripting.filesystemobject") Set objFile = objFSO.GetFile(TargetFile) FileSize = objFile.Size / 1024 If FileSize < 140000 Then Call oBag.AddValue("State", "erro") Else Call oBag.AddValue("State", "ok") End If Call oAPI.AddItem(oBag) Call oAPI.Return(oBag) Unhealthy expression: Property[@Name='State'] Equals erro Health expression: Property[@Name='State'] Equals ok If anyone can shed some light onto what I might be missing, that would be great!

  • Querying a Cassandra column family for rows that have not been updated in X days

    - by knorv
    I'm moving an existing MySQL based application over to Cassandra. So far finding the equivalent Cassandra data model has been quite easy, but I've stumbled on the following problem for which I'd appreciate some input: Consider a MySQL table holding millions of entities: CREATE TABLE entities ( id INT AUTO_INCREMENT NOT NULL, entity_information VARCHAR(...), entity_last_updated DATETIME, PRIMARY KEY (id), KEY (entity_last_updated) ); The table is regularly queried for entities that need to be updated: SELECT id FROM entities WHERE entity_last_updated IS NULL OR entity_last_updated < DATE_ADD(NOW(), INTERVAL -7*24 HOUR) ORDER BY entity_last_updated ASC; The entities returned by this queries are then updated using the following query: UPDATE entities SET entity_information = ?, entity_last_updated = NOW() WHERE id = ?; What would be the corresponding Cassandra data model that would allow me to store the given information and effectively query the entities table for entities that need to be updated (that is: entities that have not been updated in the last seven days)?

  • two computers on same network cannot ping eachother nor view NetBios resources

    - by slava
    I'd like to find out the problem of my network configuration I have network configuration is like in this diagram: The problem is between laptop1 and laptop2. At first I thought it was samba server problem. I was configuring samba server on one of the laptops and I wasn't able to access the shares from the second laptop no matter what I was doing. After installing/removing/configuring samba-server a couple of times I realized that the problem resides somewhere else. Laptop configurations: - Laptop1: ubuntu 12.04 - Laptop2: Windows 7/ ubuntu 12.04 ( dual boot ) - Server : ubuntu 12.04 When I do "ping 192.168.0.10" from laptop2, I get "Destination host unreachable". The same situation is when I ping in other direction. When I access Laptop1 shares from Laptop2, having windows 7 loaded, I get the error message: "Error code: 0x80070035 The network path was not found." When I ping "server" or "router" or "wifi router" from any of laptops I get a reply. The same with windows shares, I am able to access "server"s shares from Windows and Ubuntu, from any of my laptops. Netbios can't function correctly, that's obvious, I am unable to access windows shares between laptops. I assume that on "wifi router" is a miss-configuration, but I can't find what specifically. The "Wifi router" works as Hub + wifi, it is connected to "router" not in WAN port but in LAN1. Please, help me correctly configure the router to make them see each-other, or at least make NetBios work correctly, between laptops, to be able to access windows shares. Thanks!

  • Nullable Date column merge problem

    - by Vladimir
    I am using JPA with openjpa implementation beneath, on a Geronimo application server. I am also using MySQL database. I have a problem with updating object with nullable Date property. When I'm trying to merge entity with Date property set to null, no sql update script is generated (or when other fields are modified, sql update script is generated, but date field is ommited from it). If date field is set to some other not null value, update script is properly generated. Did anyone have problem like that?

  • Two virtual computers using one laptop?

    - by JP19
    Hi, I have a laptop and an external display. I am able to use the external display either as extended desktop OR duplicate desktop. I also use a separate keyboard and mouse. So effectively, the laptop acts just as a box without display. I want to know is it possible to use the laptop as 2 virtual PCs. (with separate control). I.E., one person uses the laptop as a laptop, and other person can simultaneously connect a keyboard and mouse and the external display and effectively get a second PC. OS I am using - windows (thought solution for other OSes are welcome). Laptop is a Dell Precision M6300. thanks JP

  • Detecting duplicate values in a column of a Datatable while traversing through It

    - by Ashish Gupta
    I have a Datatable with Id(guid) and Name(string) columns. I traverse through the data table and run a validation criteria on the Name (say, It should contain only letters and numbers) and then adding the corresponding Id to a List If name passes the validation. Something like below:- List<Guid> validIds=new List<Guid>(); foreach(DataRow row in DataTable1.Rows) { if(IsValid(row["Name"]) { validIds.Add((Guid)row["Id"]); } } In addition to this validation I should also check If the name is not repeating in the whole datatable (even for the case-sensitiveness), If It is repeating, I should not add the corresponding Id in the List. Things I am thinking/have thought about:- 1) I can have another List, check for the "Name" in the same, If It exists, will add the corresponding Guild 2) I cannot use HashSet as that would treat "Test" and "test" as different strings and not duplicates. 3) Take the DataTable to another one where I have the disctict names (this I havent tried and the code might be incorrect, please correct me whereever possible) DataTable dataTableWithDistinctName = new DataTable(); dataTableWithDistinctName.CaseSensitive=true CopiedDataTable=DataTable1.DefaultView.ToTable(true,"Name"); I would loop through the original datatable and check the existence of the "Name" in the CopiedDataTable, If It exists, I wont add the Id to the List. Are there any better and optimum way to achieve the same? I need to always think of performance. Although there are many related questions in SO, I didnt find a problem similar to this. If you could point me to a question similar to this, It would be helpful. Thanks

  • How to "interleave" two DataTables.

    - by Brent
    Take these two lists: List 1 Red Green Blue List 2 Brown Red Blue Purple Orange I'm looking for a way to combine these lists together to produce: List 3 Brown Red Green Blue Purple Orange I think the basic rules are these: 1) Insert on top the list any row falling before the first common row (e.g., Brown comes before the first common row, Red); 2) Insert items between rows if both lists have two items (e.g., List 1 inserts Green between Red and Blue); and 3) Insert rows on the bottom if the there's no "between-ness" found in 2 (e.g., List 2 inserts Orange at the bottom). The lists are stored in a DataTable. I'm guessing I'll have to switch between them while iterating, but I'm having a hard time figuring out a method of combining the rows. Thanks for any help. --Brent

I also tried to use cmake, but I gave upon that one quickly, because I don't know much about flex and bison.

  • Linux: Combine two partitions?

    - by Jakobud
    This workstation is running Fedora 11. It has 4 HDDs raided into 4 partitions: / (31 gig) /boot (134 meg) /data (140 gig) /FC12 (31 gig) The previous employee that used my current workstation set it up this way. He apparently created the FC12 partition to test a Fedora 12 installation. I don't need Fedora 12 so I wiped that partition and now I'm wondering if its possible for me to combine the /FC12 partition into the / partition, so that the / partition will now be 62 gigs. Is this possible? If so, how? Can it be done w/o reinstalling the OS? I've toyed with Fedora's LVM admin interface but it seems very basic and there doesn't seem to be anything about combining partitions. I've also messed with other HDD utilities that are in Fedora (Palimpsest Disk Utlity) but all it seems to be able to do is mount and umount partitions.

  • WPF - Make two controls the same size

    - by John Michaels
    Is there any way to make two controls that are in different containers the same size in WPF? For example, suppose you have two textboxes: textbox1 and textbox2. Textbox1 is in a grid and its size can grow and shrink when the user resizes the window. Textbox2 is in another part of the window and I need it to always have the same size as textbox1. Is there any way to do this? Keep in mind SharedSizeGroup will not work because the textboxes are in different containers. Also, I've tried binding textbox2's height property to textbox1 and that doesn't seem to work either. Finally, I tried catching textbox1's SizeChanged event, but its Height property is always NaN for some reason.

  • Two internet connections coming in, one Sonicwall Tz170 (enhanced os), and slow speed

    - by Development 4.0
    I work a lot from my home office and being in general a tad paranoid I have cable and DSL pipes coming into my house. I have used an Ebay bought Sonicwall Tz170 with the enhanced OS for a good while. I believe it does failover and has a feature for doing round robin on which connection is used. I get the impression from using it that I might not be getting the most out of this setup. Is it possible/likely that my router could be a cause of the slowdown? Are there more appropriate choices?

  • Find the minimum gap between two numbers in an AVL tree

    - by user1656647
    I have a data structures homework, that in addition to the regular AVL tree functions, I have to add a function that returns the minimum gap between any two numbers in the AVL tree (the nodes in the AVL actually represent numbers.) Lets say we have the numbers (as nodes) 1 5 12 20 23 21 in the AVL tree, the function should return the minimum gap between any two numbers. In this situation it should return "1" which is |20-21| or |21-20|. It should be done in O(1). Tried to think alot about it, and I know there is a trick but just couldn't find it, I have spent hours on this. There was another task which is to find the maximum gap, which is easy, it is the difference between the minimal and maximal number.

  • It seems Windows 8.1 killed my two T60 laptop batteries

    - by rstock
    Upgraded Windows 7 to Win8 earlier this year, and last week upgraded to Windows 8.1. (Lenovo T60) Had no problem with battery usage when on Win7 nor Win8. After about a week of Win8.1 on my system, the battery stop working, while the system was on. The orange batt. indicator just keeps flashing. The system does not charge the battery (even though I know there was life in it). I installed a known good fully charged battery from another T60, it worked for aboute 40 mins then it instantly died in fron of my eyes. The system now shows the same orange flashing batt. light, but it is not charging. I know both these batteries are still good, they just appear to be dead. My research suggest that the new Win8.1 may not have updated the battery driver to Win8. I have since done that. Same problem. Research i s also pointing me to some 'smart chip' on the batteries that need to a reset. Is this possible ?? Does anyone know a process to reset the 'smart chip' on these batteries (fru# 92P1139) ????
