  • Css and different size of monitor?

    - by studdler
    Hi, I am doing a website (WIP). I encountered some css problems, hope you guys can help me. My current situation: I have am image, lets called it "bg.png" with the width about 2500px, and at the center of the background image has my logo. My website should target all size (from small 800 x 600 to 2400 x XXX) users. My problems How do I centralize the background image(bg.png), so that the logo always positioned in the centered(horizontally) of different size of monitors screen?

  • C++ Multi Monitor - Find All Visible/Open Windows

    - by Paul
    I'm trying to find all the windows of ANY kind that are open (and have a taskbar 'button'). I have no problems finding the list processes/hWnd's, and then cycling through those, but how do I determine if a process/hwnd has a window open? (even if minimized). I've tried doing different combinations of the window parameters (such as WS_POPUP etc) but none of the parameters (or combinations of parameters) that I could find would give me all the open windows without some sort of false positives. As an example of a false positive was the fact that it gives me two 'windows' for google talk (even though one was open). Another false positive is considering the start menu as an open window. Any ideas? Solutions? I've been working on this for a while and its been driving me a bit insane. Note: I'm doing this for windows 7 (at this point). I'm not sure if there's any difference between how you would do this between XP and 7, but I thought it might be relevant.

  • Configuration tools for multiple monitors for X / Linux

    - by richard
    I have Ubuntu 10.04 running gnome and two monitors. I am wondering if a can get a better multi-monitor configuration tool. The one I have, gnome-display-properties, has too many problems, including: When I swapped my monitors over, the narrower (external) one now on the left. There is a width calculation error, such that I have a virtual monitor the width of the wide-monitor on the narrow-monitor and part of the wide monitor. And a virtual narrow-monitor on the remainder of the wide-monitor. Also the visible mouse pointer does is not aligned with the active spot, an x offset of one monitor width. I would like, in approximate order of importance: nobugs. to be able to select which is primary monitor. to have multiple configurations. configurations to be automatically selected based on which monitors are attached. configurations to be cycled (reliably) when display mode key is pressed. when a display is deactivated, for windows to migrate to remaining monitors. option to not change display resolution when mirroring, but to use side/top blanking bars to pad out screen.

  • Using JMX classes to notify on events over time

    - by Cincinnati Joe
    I've been looking at JMX for monitoring application and system metrics (partially because MBeans can accessed by various tools such as JConsole). It would seem like the classes included with JMX would be useful for things like notification when metrics have exceeded thresholds. But I'm not sure they fit with the way I want to measure these over a specified time period. For example, let's say I want to notify an admin when the average CPU load is over 95% for more than 5 minutes. Is that something can be done with a GaugeMonitor? From the docs, it doesn't seem quite suited for this, and I'm wondering if instead I should write my own MBean with the necessary logic. A more relevant example is when the login times for users exceed 10s over a period of 5 mins. Slightly different would be the last 20 logins took more than 10s on average. Another case would be when a process crashes 4+ times in an hour. Or the request queue exceeds 15 for 5 mins. Are the JMX Monitor classes useful for this kind of thing?

  • Why isn't my monitor's native resolution appearing as an option?

    - by Warren Pena
    I'm on a clean install of Ubuntu 10.04 LTS. My monitor's native resolution is 1280x1024. However, in the Monitor Preferences application, I am only presented with 640x480 and 800x600 as options. My video card is an on board Matrox G200eW. I tried installing the proprietary driver from Matrox's website, but the installer immediately throws four errors. I also tried using xrandr to set my resolution, but it simply pops back saying "Size 1280x1024 not found in available modes." How can I get 1280x1024 added to my available sizes to that I can switch to it?

  • How do I get one monitor on top of the other in Ubuntu 10.10?

    - by Jan
    I'm using a laptop and a monitor (wall mounted) over my laptop. I would like to reflect this physical hardware setup in my software screen setup. So that I can move my mouse upward, out of my laptop screen and use the monitor on the wall. I have been searching for a solution for a while, and I hope somone can help me out. I'm using Ubuntu 10.10 "out of the box". Side by side screen setups works just fine, over/under is doesn't work.

  • Port mirroring on multiple switches

    - by Matt
    So here is the deal, I have a server on switch A where port 3 is monitoring traffic for most of the ports on switch A. However I have other users on switch B that needs to have port 3 on switch A monitor as well. Is this possible? I have been reading about rspan but doesnt seem to work. Switch A: monitor session 1 source interface fast0/1 - 2 monitor session 1 source interface fast0/4 - 46 monitor session 1 destination interface fast0/3 (this works great for switch A, I need a solution to get switch B to also have some ports sent to port 3 on switch A for monitoring.) Onxx, All the traffic on switch A is fine, there will be about 10-15 ports on switch B that I need to send to fa0/3 on switch A as the destination. I have the switches connected with a ethernet cable with a trunk port on both switches on port 48 on switch B and A and port 47 on A connects to our sonicwall. So I am assuming they are daisy chained? What if I did the following: Switch A monitor session 1 source interface fast0/1 - 2 monitor session 1 source interface fast0/4 - 46 monitor session 1 destination interface fast0/3 Put all of the ports on vlan 10 because I made an rspan vlan 10 On switch B monitor the ports I need will say 1-10 monitor session 1 source interface fast0/1 - 10 monitor session 1 destination remote vlan 10 as a prerequisite I would have created vlan 10 as a rspan vlan on switch B. Switch A Monitor session 1 destination remote vlan 10 Would this work? By the way I am working with cisco catalyst 3560 switches.

  • Workspeace view shows first workspaces out of border at left

    - by Jeremi Roivas
    I am using nvidia-current and edited from settings my monitors so that my second monitor is at left and unity-panel shows only in my main monitor. How ever now the workspaces images have shifted so that second monitor first workpsaces are moved out of the left border and when the monitor is not turn on I can't see the the workspaces there. Sometimes programs have been moved when monitor is been flashed to the workspace shown in out of border and I have no means to move the program windows into my main workspace views. Image: http://but.fi/2em As you see the second monitor works as it should work but my main monitor is fooked. Is this possible way to fix this some how?

  • How to tell Windows 7 "sleep when laptop is closed, unless there's an external monitor connected; then use that"?

    - by Josh
    Most of the time, I would like my Windows 7 laptop to sleep when I close it. But sometimes, I like to connect an external monitor over DVI. I would like my laptop to use the external monitor when I close the lid, but only when a monitor is connected to the DVI port. Otherwise, sleep when closed. Is there any way I can do that, without manually changing the power settings every time I decide to use the monitor?

  • amd gpu but display on intel integrated graphics

    - by pitseeker
    On my Ubuntu 12.04 I connected my monitor to the onboard intel graphics. I'd like to use my ati radeon 6770 for opencl tasks (e.g. bitcoin mining). So far I couldn't figure out how to get the ati driver working. When calling "aticonfig --initial -f" it always writes a new xorg.conf that ignores the intel graphics. At boot time it works only when I attached the monitor to the ati card. So I manually tampered with the xorg.conf and got this: Section "ServerLayout" Identifier "Default Monitor" Screen 0 "myscreen" 0 0 Screen 1 "deadscreen" RightOf "myscreen" EndSection Section "Module" EndSection Section "Monitor" Identifier "Default Monitor" Option "VendorName" "Monitor Vendor" Option "ModelName" "Monitor Name" Option "DPMS" "true" EndSection Section "Monitor" Identifier "null Monitor" Option "Enable" "false" EndSection Section "Device" Identifier "Intel Integrated Graphics" Driver "intel" BusID "PCI:0:2:0" Screen 0 EndSection Section "Device" Identifier "aticonfig-Device[0]-0" Driver "fglrx" BusID "PCI:1:0:0" Screen 1 EndSection Section "Screen" Identifier "myscreen" Device "Intel Integrated Graphics" Monitor "Default Monitor" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection Section "Screen" Identifier "deadscreen" Device "aticonfig-Device[0]-0" Monitor "null Monitor" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection I think this might be the right way since I see that X tries to start both drivers in /var/log/Xorg.0.log.

  • Linux clock loses 10 minutes every week

    - by PaKempf
    One of my linux server's clock loses 10 minutes every now and then, nearly every week. I update the time so it stays correct, and although it doesn't really bother me, i'd like to fix it. I've been searching around a bit. Nothing can be responsible in the crontab, and i can't find any related message in the logs. Some people seem to use ntp to fix that kind of issue, but i'd prefer not to use an unecessary component on it.

  • Ubuntu: Failure to login with multiple video adapters

    - by tsilb
    Forgive my ignorance, for I am a complete linux noob. I have a computer with three video cards and six monitors. Works great on Windows. Trying to get it to run Ubuntu as well. It loads fine when I have it configured to run on one adapter; detects both screens, runs ok. But I want to turn the other 4 monitors on and run the whole thing as one extended desktop (one session, etc). So I downloaded and installed the newest ATI driver for Linux, which seems to work, kinda. I ran this to set up the screens: aticonfig --adapter=all --initial -f Now when I boot, Ubuntu seems to turn on all the screens (3 viewports, each with two cloned displays from what I can tell). When I enter my login info OR move the mouse off the main screen, the screens freeze and the kbd/ms become unresponsive. aticonfig generated xorg.conf included below. Have tried the following: aticonfig -initial -f - works, but only detects the primary adapter and 2 screens aticccle - Tells me I have to reboot after enabling the other cards. Then goes into above described freezing state. aticonfig --adapter=all --initial -f - see above Manually editing xorg.conf file with my limited knowledge - Was able to get two adapters running, but only the second adapter initialized while the primary stopped at the Ubuntu boot screen. Was unable to see the login prompt. Froze after I logged in blindly (was able to hear the login sound). Using generic "radeon" driver instead of ATI Proprietary driver with the above init attempts Toggling xinerama Various combinations of the above Hardware: Intel Core 2 Quad q6600 8GB DDR2 (3x) ATI Radeon HD 4680 5 monitors (21W, 21W, 22W Portrait, 22W Portrait, 19")and an HDTV (26"W, HDMI) in a horizontal arrangement I know next to nothing about Linux/Ubuntu aside from basic filesystem navigation, editing text files, and accessing my local and networked Windows stores and shares.

  • Entity Framework v1 &ndash; tips and Tricks Part 3

    - by Rohit Gupta
    General Tips on Entity Framework v1 & Linq to Entities: ToTraceString() If you need to know the underlying SQL that the EF generates for a Linq To Entities query, then use the ToTraceString() method of the ObjectQuery class. (or use LINQPAD) Note that you need to cast the LINQToEntities query to ObjectQuery before calling TotraceString() as follows: 1: string efSQL = ((ObjectQuery)from c in ctx.Contact 2: where c.Address.Any(a => a.CountryRegion == "US") 3: select c.ContactID).ToTraceString(); ================================================================================ MARS or MultipleActiveResultSet When you create a EDM Model (EDMX file) from the database using Visual Studio, it generates a connection string with the same name as the name of the EntityContainer in CSDL. In the ConnectionString so generated it sets the MultipleActiveResultSet attribute to true by default. So if you are running the following query then it streams multiple readers over the same connection: 1: using (BAEntities context = new BAEntities()) 2: { 3: var cons = 4: from con in context.Contacts 5: where con.FirstName == "Jose" 6: select con; 7: foreach (var c in cons) 8: { 9: if (c.AddDate < new System.DateTime(2007, 1, 1)) 10: { 11: c.Addresses.Load(); 12: } 13: } 14: } ================================================================================= Explicitly opening and closing EntityConnection When you call ToList() or foreach on a LINQToEntities query the EF automatically closes the connection after all the records from the query have been consumed. Thus if you need to run many LINQToEntities queries over the same connection then explicitly open and close the connection as follows: 1: using (BAEntities context = new BAEntities()) 2: { 3: context.Connection.Open(); 4: var cons = from con in context.Contacts where con.FirstName == "Jose" 5: select con; 6: var conList = cons.ToList(); 7: var allCustomers = from con in context.Contacts.OfType<Customer>() 8: select con; 9: var allcustList = allCustomers.ToList(); 10: context.Connection.Close(); 11: } ====================================================================== Dispose ObjectContext only if required After you retrieve entities using the ObjectContext and you are not explicitly disposing the ObjectContext then insure that your code does consume all the records from the LinqToEntities query by calling .ToList() or foreach statement, otherwise the the database connection will remain open and will be closed by the garbage collector when it gets to dispose the ObjectContext. Secondly if you are making updates to the entities retrieved using LinqToEntities then insure that you dont inadverdently dispose of the ObjectContext after the entities are retrieved and before calling .SaveChanges() since you need the SAME ObjectContext to keep track of changes made to the Entities (by using ObjectStateEntry objects). So if you do need to explicitly dispose of the ObjectContext do so only after calling SaveChanges() and only if you dont need to change track the entities retrieved any further. ======================================================================= SQL InjectionAttacks under control with EFv1 LinqToEntities and LinqToSQL queries are parameterized before they are sent to the DB hence they are not vulnerable to SQL Injection attacks. EntitySQL may be slightly vulnerable to attacks since it does not use parameterized queries. However since the EntitySQL demands that the query be valid Entity SQL syntax and valid native SQL syntax at the same time. So the only way one can do a SQLInjection Attack is by knowing the SSDL of the EDM Model and be able to write the correct EntitySQL (note one cannot append regular SQL since then the query wont be a valid EntitySQL syntax) and append it to a parameter. ====================================================================== Improving Performance You can convert the EntitySets and AssociationSets in a EDM Model into precompiled Views using the edmgen utility. for e.g. the Customer Entity can be converted into a precompiled view using edmgen and all LinqToEntities query against the contaxt.Customer EntitySet will use the precompiled View instead of the EntitySet itself (the same being true for relationships (EntityReference & EntityCollections of a Entity)). The advantage being that when using precompiled views the performance will be much better. The syntax for generating precompiled views for a existing EF project is : edmgen /mode:ViewGeneration /inssdl:BAModel.ssdl /incsdl:BAModel.csdl /inmsl:BAModel.msl /p:Chap14.csproj Note that this will only generate precompiled views for EntitySets and Associations and not for existing LinqToEntities queries in the project.(for that use CompiledQuery.Compile<>) Secondly if you have a LinqToEntities query that you need to run multiple times, then one should precompile the query using CompiledQuery.Compile method. The CompiledQuery.Compile<> method accepts a lamda expression as a parameter, which denotes the LinqToEntities query  that you need to precompile. The following is a example of a lamda that we can pass into the CompiledQuery.Compile() method 1: Expression<Func<BAEntities, string, IQueryable<Customer>>> expr = (BAEntities ctx1, string loc) => 2: from c in ctx1.Contacts.OfType<Customer>() 3: where c.Reservations.Any(r => r.Trip.Destination.DestinationName == loc) 4: select c; Then we call the Compile Query as follows: 1: var query = CompiledQuery.Compile<BAEntities, string, IQueryable<Customer>>(expr); 2:  3: using (BAEntities ctx = new BAEntities()) 4: { 5: var loc = "Malta"; 6: IQueryable<Customer> custs = query.Invoke(ctx, loc); 7: var custlist = custs.ToList(); 8: foreach (var item in custlist) 9: { 10: Console.WriteLine(item.FullName); 11: } 12: } Note that if you created a ObjectQuery or a Enitity SQL query instead of the LINQToEntities query, you dont need precompilation for e.g. 1: An Example of EntitySQL query : 2: string esql = "SELECT VALUE c from Contacts AS c where c is of(BAGA.Customer) and c.LastName = 'Gupta'"; 3: ObjectQuery<Customer> custs = CreateQuery<Customer>(esql); 1: An Example of ObjectQuery built using ObjectBuilder methods: 2: from c in Contacts.OfType<Customer>().Where("it.LastName == 'Gupta'") 3: select c This is since the Query plan is cached and thus the performance improves a bit, however since the ObjectQuery or EntitySQL query still needs to materialize the results into Entities hence it will take the same amount of performance hit as with LinqToEntities. However note that not ALL EntitySQL based or QueryBuilder based ObjectQuery plans are cached. So if you are in doubt always create a LinqToEntities compiled query and use that instead ============================================================ GetObjectStateEntry Versus GetObjectByKey We can get to the Entity being referenced by the ObjectStateEntry via its Entity property and there are helper methods in the ObjectStateManager (osm.TryGetObjectStateEntry) to get the ObjectStateEntry for a entity (for which we know the EntityKey). Similarly The ObjectContext has helper methods to get an Entity i.e. TryGetObjectByKey(). TryGetObjectByKey() uses GetObjectStateEntry method under the covers to find the object, however One important difference between these 2 methods is that TryGetObjectByKey queries the database if it is unable to find the object in the context, whereas TryGetObjectStateEntry only looks in the context for existing entries. It will not make a trip to the database ============================================================= POCO objects with EFv1: To create POCO objects that can be used with EFv1. We need to implement 3 key interfaces: IEntityWithKey IEntityWithRelationships IEntityWithChangeTracker Implementing IEntityWithKey is not mandatory, but if you dont then we need to explicitly provide values for the EntityKey for various functions (for e.g. the functions needed to implement IEntityWithChangeTracker and IEntityWithRelationships). Implementation of IEntityWithKey involves exposing a property named EntityKey which returns a EntityKey object. Implementation of IEntityWithChangeTracker involves implementing a method named SetChangeTracker since there can be multiple changetrackers (Object Contexts) existing in memory at the same time. 1: public void SetChangeTracker(IEntityChangeTracker changeTracker) 2: { 3: _changeTracker = changeTracker; 4: } Additionally each property in the POCO object needs to notify the changetracker (objContext) that it is updating itself by calling the EntityMemberChanged and EntityMemberChanging methods on the changeTracker. for e.g.: 1: public EntityKey EntityKey 2: { 3: get { return _entityKey; } 4: set 5: { 6: if (_changeTracker != null) 7: { 8: _changeTracker.EntityMemberChanging("EntityKey"); 9: _entityKey = value; 10: _changeTracker.EntityMemberChanged("EntityKey"); 11: } 12: else 13: _entityKey = value; 14: } 15: } 16: ===================== Custom Property ==================================== 17:  18: [EdmScalarPropertyAttribute(IsNullable = false)] 19: public System.DateTime OrderDate 20: { 21: get { return _orderDate; } 22: set 23: { 24: if (_changeTracker != null) 25: { 26: _changeTracker.EntityMemberChanging("OrderDate"); 27: _orderDate = value; 28: _changeTracker.EntityMemberChanged("OrderDate"); 29: } 30: else 31: _orderDate = value; 32: } 33: } Finally you also need to create the EntityState property as follows: 1: public EntityState EntityState 2: { 3: get { return _changeTracker.EntityState; } 4: } The IEntityWithRelationships involves creating a property that returns RelationshipManager object: 1: public RelationshipManager RelationshipManager 2: { 3: get 4: { 5: if (_relManager == null) 6: _relManager = RelationshipManager.Create(this); 7: return _relManager; 8: } 9: } ============================================================ Tip : ProviderManifestToken – change EDMX File to use SQL 2008 instead of SQL 2005 To use with SQL Server 2008, edit the EDMX file (the raw XML) changing the ProviderManifestToken in the SSDL attributes from "2005" to "2008" ============================================================= With EFv1 we cannot use Structs to replace a anonymous Type while doing projections in a LINQ to Entities query. While the same is supported with LINQToSQL, it is not with LinqToEntities. For e.g. the following is not supported with LinqToEntities since only parameterless constructors and initializers are supported in LINQ to Entities. (the same works with LINQToSQL) 1: public struct CompanyInfo 2: { 3: public int ID { get; set; } 4: public string Name { get; set; } 5: } 6: var companies = (from c in dc.Companies 7: where c.CompanyIcon == null 8: select new CompanyInfo { Name = c.CompanyName, ID = c.CompanyId }).ToList(); ;

  • Tips &amp; Tricks: How to crawl a SSL enabled Oracle E-Business Suite

    - by Rajesh Ghosh
    Oracle E-Business Suite can be integrated with Oracle Secure Enterprise Search for a superior end user experience and enhanced data retrieval capabilities. Before end-users can perform search operations, data has to be crawled and indexed into Oracle SES server. However if the Oracle E-Business Suite instance is on SSL, some additional configurations are needed in Oracle SES server as well as in Oracle Search Modeler, before a search object can be deployed and crawled. The process involves the following steps: Step 1: Export the SSL certificate of Oracle E-Business Suite Access the Oracle E-business Suite instance from a web browser. You should be able to locate a security or certificate icon somewhere in the browser toolbar or status bar, depending on which browser you are using. Click on it and you should be able to view the certificate as well as export it to a local file. While exporting make sure that you use “DER encoded” format. Step 2: Import the SSL certificate into Oracle Secure Enterprise server’s java key-store Oracle SES (10.1.8.4) by default ships a JDK under $ORACLE_HOME. The Oracle SES mid-tier uses this jdk to start the oc4j container services. In this step the Oracle E-Business Suite’s SSL certificate which has been exported in step #1, has to be imported into the Oracle SES server’s java key store. Perform the following: Copy the certificate file onto the server where Oracle SES server is running; under $ORACLE_HOME/jdk/jre/lib/security/cacerts. “ORACLE_HOME” points to the Oracle SES oracle home. Set the JAVA_HOME environment variable to $ORACLE_HOME/jdk. Append $JAVA_HOME/bin to the PATH environment variable Issue the command :  “keytool -import -keystore keystore.jks -trustcacerts -alias myOHS –file ebs.crt” . Please substitute “ebs.crt” with the name of the certificate file you copied in step #2.1. The default key-store password “changeit”. Enter the same when prompted. If successful this process will end with a message saying “certificate successfully imported”. Step 3: Import the SSL certificate into Search Modeler java key-store Unlike Oracle SES, Search Modeler is not shipped with a bundled JDK. If you are using standalone OC4J, then you actually use an external JDK to start the oc4j container services. If you are using IAS instance then the JDK comes bundled with the IAS installation. Perform the following: Copy the certificate file onto the server where Search Modeler application is running; under $JDK_HOME/jre/lib/security/cacerts. “JDK_HOME” points to the JDK directory depending on whether you are using external JDK or a bundled one. Set the JAVA_HOME environment variable to JDK directory. Append $JAVA_HOME/bin to the PATH environment variable Issue the command :  “keytool -import -keystore keystore.jks -trustcacerts -alias myOHS –file ebs.crt” . Please substitute “ebs.crt” with the name of the certificate file you copied in step #3.1. The default key-store password “changeit”. Enter the same when prompted. If successful this process will end with a message saying “certificate successfully imported”. Once you have completed the above steps successfully, you can deploy the search objects using Search Modeler and then start crawling them as well.

  • Blind As a Bat in Multi-Monitor Hell &ndash; Free Program Inside!

    - by ToStringTheory
    If you know me personally, then you probably know that I am going blind thanks to a rare genetic eye disease.  My eye disease has already been a huge detriment to my eyesight.  One of the big things to suffer is my ability to see small things moving fast right in front of me.  On a multi-monitor setup, this makes finding the cursor absolute hell. The Problem I’ll keep this short, as I’ve basically already told you what the problem is.  On my three monitor development computer, I am constantly losing the mouse during the day.  I had used the Microsoft accessibility mousefinder (press CTRL, and it pings around the mouse).  The problem with this is, there is only an effect around 50-100 PX around the mouse, and it is a very light gray, almost unnoticeable.. For someone like me, if I am not looking at the monitor when I click the CTRL button, I have to click it multiple times and dart my eyes back and forth in a futile attempt to catch a glimpse of the action…  I had tried other cursor finders, but none I liked… The Solution So what’s a guy to do when he doesn’t like his options?  MAKE A NEW OPTION…  What else should we as developers do, am I right?  So, I went ahead and made a mousefinder of my own, with 6 separate settings to change the effect.  I am releasing it here for anyone else that may also have problems finding their mouse at times. Some of its features include: Multiple options to change to achieve the exact effect you want. If your mouse moves while it is honing in, it will hone in on its current position. Many times, I would press the button and move my mouse at the same time, and many times, the mouse happened to be at a screen edge, so I would miss it. This program will restart its animation on a new screen if the mouse changes its screen while playing. Tested on Windows 7 x64 Stylish color changing from green to red. Deployed as a ClickOnce, so easy to remove if you don't like it. Press Right CTRL to trigger effect Application lives in notification area so that you can easily reach configuration or close it. To get it to run on startup, copy its application shortcut from its startmenu directory to the “Startup” folder in your startmenu. Conclusion I understand if you don’t download this…  You don’t know me and I don’t know you.  I can only say that I have honestly NOT added any virus’ or malware to the package. Yeah, I know it’s weird Download: ‘ToString(theory) Mousefinder.zip’ CRC32: EEBCE300 MD5: 0394DA581BE6F3371B5BA11A8B24BC91 SHA-1: 2080C4930A2E7D98B81787BB5E19BB24E118991C Finally, if you do use this application - please leave a comment, or email me and tell me what you think of it.

  • Part 3 of 4 : Tips/Tricks for Silverlight Developers.

    - by mbcrump
    Part 1 | Part 2 | Part 3 | Part 4 I wanted to create a series of blog post that gets right to the point and is aimed specifically at Silverlight Developers. The most important things I want this series to answer is : What is it?  Why do I care? How do I do it? I hope that you enjoy this series. Let’s get started: Tip/Trick #11) What is it? Underline Text in a TextBlock. Why do I care? I’ve seen people do some crazy things to get underlined text in a Silverlight Application. In case you didn’t know there is a property for that. How do I do it: On a TextBlock you have a property called TextDecorations. You can easily set this property in XAML or CodeBehind with the following snippet: <UserControl x:Class="SilverlightApplication19.MainPage" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="400"> <Grid x:Name="LayoutRoot" Background="White"> <TextBlock Name="txtTB" Text="MichaelCrump.NET" TextDecorations="Underline" /> </Grid> </UserControl> or you can do it in CodeBehind… txtTB.TextDecorations = TextDecorations.Underline;   Tip/Trick #12) What is it? Get the browser information from a Silverlight Application. Why do I care? This will allow you to program around certain browser conditions that otherwise may not be aware of. How do I do it: It is very easy to extract Browser Information out a Silverlight Application by using the BrowserInformation class. You can copy/paste this code snippet to have access to all of them. string strBrowserName = HtmlPage.BrowserInformation.Name; string strBrowserMinorVersion = HtmlPage.BrowserInformation.BrowserVersion.Minor.ToString(); string strIsCookiesEnabled = HtmlPage.BrowserInformation.CookiesEnabled.ToString(); string strPlatform = HtmlPage.BrowserInformation.Platform; string strProductName = HtmlPage.BrowserInformation.ProductName; string strProductVersion = HtmlPage.BrowserInformation.ProductVersion; string strUserAgent = HtmlPage.BrowserInformation.UserAgent; string strBrowserVersion = HtmlPage.BrowserInformation.BrowserVersion.ToString(); string strBrowserMajorVersion = HtmlPage.BrowserInformation.BrowserVersion.Major.ToString(); Tip/Trick #13) What is it? Always check the minRuntimeVersion after creating a new Silverlight Application. Why do I care? Whenever you create a new Silverlight Application and host it inside of an ASP.net website you will notice Visual Studio generates some code for you as shown below. The minRuntimeVersion value is set by the SDK installed on your system. Be careful, if you are playing with beta’s like “Lightswitch” because you will have a higher version of the SDK installed. So when you create a new Silverlight 4 project and deploy it your customers they will get a prompt telling them they need to upgrade Silverlight. They also will not be able to upgrade to your version because its not released to the public yet. How do I do it: Open up the .aspx or .html file Visual Studio generated and look for the line below. Make sure it matches whatever version you are actually targeting. Tip/Trick #14) What is it? The VisualTreeHelper class provides useful methods for involving nodes in a visual tree. Why do I care? It’s nice to have the ability to “walk” a visual tree or to get the rendered elements of a ListBox. I have it very useful for debugging my Silverlight application. How do I do it: Many examples exist on the web, but say that you have a huge Silverlight application and want to find the parent object of a control.  In the code snippet below, we would get 3 MessageBoxes with (StackPanel first, Grid second and UserControl Third). This is a tiny application, but imagine how helpful this would be on a large project. <UserControl x:Class="SilverlightApplication18.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="400"> <Grid x:Name="LayoutRoot" Background="White"> <StackPanel> <Button Content="Button" Height="23" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" /> </StackPanel> </Grid> </UserControl> private void button1_Click(object sender, RoutedEventArgs e) { DependencyObject obj = button1; while ((obj = VisualTreeHelper.GetParent(obj)) != null) { MessageBox.Show(obj.GetType().ToString()); } } Tip/Trick #15) What is it? Add ChildWindows to your Silverlight Application. Why do I care? ChildWindows are a great way to direct a user attention to a particular part of your application. This could be used when saving or entering data. How do I do it: Right click your Silverlight Application and click Add then New Item. Select Silverlight Child Window as shown below. Add an event and call the ChildWindow with the following snippet below: private void button1_Click(object sender, RoutedEventArgs e) { ChildWindow1 cw = new ChildWindow1(); cw.Show(); } Your main application can still process information but this screen forces the user to select an action before proceeding. The code behind of the ChildWindow will look like the following: namespace SilverlightApplication18 { public partial class ChildWindow1 : ChildWindow { public ChildWindow1() { InitializeComponent(); } private void OKButton_Click(object sender, RoutedEventArgs e) { this.DialogResult = true; //TODO: Add logic to save what the user entered. } private void CancelButton_Click(object sender, RoutedEventArgs e) { this.DialogResult = false; } } } Thanks for reading and please come back for Part 4.  Subscribe to my feed CodeProject

  • Part 4 of 4 : Tips/Tricks for Silverlight Developers.

    - by mbcrump
    Part 1 | Part 2 | Part 3 | Part 4 I wanted to create a series of blog post that gets right to the point and is aimed specifically at Silverlight Developers. The most important things I want this series to answer is : What is it?  Why do I care? How do I do it? I hope that you enjoy this series. Let’s get started: Tip/Trick #16) What is it? Find out version information about Silverlight and which WebKit it is using by going to http://issilverlightinstalled.com/scriptverify/. Why do I care? I’ve had those users that its just easier to give them a site and say copy/paste the line that says User Agent in order to troubleshoot a Silverlight problem. I’ve also been debugging my own Silverlight applications and needed an easy way to determine if the plugin is disabled or not. How do I do it: Simply navigate to http://issilverlightinstalled.com/scriptverify/ and hit the Verify button. An example screenshot is located below: Results from Chrome 7 Results from Internet Explorer 8 (With Silverlight Disabled) Tip/Trick #17) What is it? Use Lambdas whenever you can. Why do I care?  It is my personal opinion that code is easier to read using Lambdas after you get past the syntax. How do I do it: For example: You may write code like the following: void MainPage_Loaded(object sender, RoutedEventArgs e) { //Check and see if we have a newer .XAP file on the server Application.Current.CheckAndDownloadUpdateAsync(); Application.Current.CheckAndDownloadUpdateCompleted += new CheckAndDownloadUpdateCompletedEventHandler(Current_CheckAndDownloadUpdateCompleted); } void Current_CheckAndDownloadUpdateCompleted(object sender, CheckAndDownloadUpdateCompletedEventArgs e) { if (e.UpdateAvailable) { MessageBox.Show( "An update has been installed. To see the updates please exit and restart the application"); } } To me this style forces me to look for the other Method to see what the code is actually doing. The style located below is much easier to read in my opinion and does the exact same thing. void MainPage_Loaded(object sender, RoutedEventArgs e) { //Check and see if we have a newer .XAP file on the server Application.Current.CheckAndDownloadUpdateAsync(); Application.Current.CheckAndDownloadUpdateCompleted += (s, e) => { if (e.UpdateAvailable) { MessageBox.Show( "An update has been installed. To see the updates please exit and restart the application"); } }; } Tip/Trick #18) What is it? Prevent development Web Service references from breaking when Visual Studio auto generates a new port number. Why do I care?  We have all been there, we are developing a Silverlight Application and all of a sudden our development web services break. We check and find out that the local port number that Visual Studio assigned has changed and now we need up to update all of our service references. We need a way to stop this. How do I do it: This can actually be prevented with just a few mouse click. Right click on your web solution and goto properties. Click the tab that says, Web. You just need to click the radio button and specify a port number. Now you won’t be bothered with that anymore. Tip/Trick #19) What is it? You can disable the Close Button a ChildWindow. Why do I care?  I wouldn’t blog about it if I hadn’t seen it. Devs trying to override keystrokes to prevent users from closing a Child Window. How do I do it: A property exist on the ChildWindow called “HasCloseButton”, you simply change that to false and your close button is gone. You can delete the “Cancel” button and add some logic to the OK button if you want the user to respond before proceeding. Tip/Trick #20) What is it? Cleanup your XAML. Why do I care?  By removing unneeded namespaces, not naming all of your controls and getting rid of designer markup you can improve code quality and readability. How do I do it: (This is a 3 in one tip) Remove unused Designer markup: 1) Have you ever wondered what the following code snippet does? xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480" This code is telling the designer to do something special with this page in “Design mode” Specifically the width and the height of the page. When its running in the browser it will not use this information and it is actually ignored by the XAML parser. In other words, if you don’t need it then delete it. 2) If you are not using a namespace then remove it. In the code sample below, I am using Resharper which will tell me the ones that I’m not using by the grayed out line below. If you don’t have resharper you can look in your XAML and manually remove the unneeded namespaces. 3) Don’t name an control unless you actually need to refer to it in procedural code. If you name a control you will take a slight performance hit that is totally unnecessary if its not being called. <TextBlock Height="23" Text="TextBlock" />   That is the end of the series. I hope that you enjoyed it and please check out Part 1 | Part 2 | Part 3 if your hungry for more.  Subscribe to my feed CodeProject

  • Generating .coverage file programmatic way with Visual Studio 2010

    - by prosseek
    I need to generate .coverage file programmatic way. This post explains a C# code to do it as follows. using System; using System.Collections.Generic; using System.Text; using System.Diagnostics; using Microsoft.VisualStudio.Coverage; using Microsoft.VisualStudio.Coverage.Analysis; // You must add a reference to Microsoft.VisualStudio.Coverage.Monitor.dll namespace Microsoft.VisualStudio { class DumpProgram { static void Main(string[] args) { Process p = new Process(); StringBuilder sb = new StringBuilder("/COVERAGE "); sb.Append("hello.exe"); p.StartInfo.FileName = "vsinstr.exe"; p.StartInfo.Arguments = sb.ToString(); p.Start(); p.WaitForExit(); // TODO: Look at return code – 0 for success // A guid is used to keep track of the run Guid myrunguid = Guid.NewGuid(); Monitor m = new Monitor(); m.StartRunCoverage(myrunguid, "hello.coverage"); // Complete the run m.FinishRunCoverage(myrunguid); Unfortunately, when I compile this code, I get the following error. bin2xml.cs(26,22): error CS0246: The type or namespace name 'Monitor' could not be found (are you missing a using directive or an assembly reference?) bin2xml.cs(26,38): error CS0246: The type or namespace name 'Monitor' could not be found (are you missing a using directive or an assembly reference?) As this post says, there are some changes between VS2008 and VS2010, I think the Monitor class is in some different namespace. What might be wrong? How can I generate the .coverage file programmatically with Visual Studio 2010? ADDED I added using System.Threading to run to get the following error. I run the command csc bin2xml.cs /r:Microsoft.VisualStudio.Coverage.Analysis.dll. bin2xml.cs(28,21): error CS0723: Cannot declare a variable of static type 'System.Threading.Monitor' bin2xml.cs(28,33): error CS0712: Cannot create an instance of the static class 'System.Threading.Monitor' bin2xml.cs(29,23): error CS1061: 'System.Threading.Monitor' does not contain a definition for 'StartRunCoverage' and no extension method 'StartRunCoverage' accepting a first argument of type 'System.Threading.Monitor' could be found (are you missing a using directive or an assembly reference?) bin2xml.cs(31,23): error CS1061: 'System.Threading.Monitor' does not contain a definition for 'FinishRunCoverage' and no extension method 'FinishRunCoverage' accepting a first argument of type 'System.Threading.Monitor' could be found (are you missing a using directive or an assembly reference?) ADDED2 I compiled the code with the following command. csc bin2xml.cs /r:Microsoft.VisualStudio.Coverage.Analysis.dll /r:Microsoft.VisualStudio.Coverage.Monitor.dll Then, I got these error messages. Monitor m = new Monitor(); is at the line 27. bin2xml.cs(27,21): error CS0246: The type or namespace name 'Monitor' could not be found (are you missing a using directive or an assembly reference?) bin2xml.cs(27,37): error CS0246: The type or namespace name 'Monitor' could not be found (are you missing a using directive or an assembly reference?)

  • What is the most time-effective way to monitor & manage threats from bots and/or humans?

    - by CheeseConQueso
    I'm usually overwhelmed by the amount of tools that hosting companies provide to track & quantify traffic data and statistics. I'm equally overwhelmed by the countless flavors of malicious 'attacks' that target any and every web site known to man. The security methods used to protect both the back and front end of a website are documented well and are straight-forward in terms of ease of implementation and application, but the army of autonomous bots knows no boundaries and will always find a niche of a website to infest. So what can be done to handle the inevitable swarm of bots that pound your domain with brute force? Whenever I look at error logs for my domains, there are always thousands of entries that look like bots trying to sneak sql code into the database by tricking the variables in the url into giving them schema information or private data within the database. My barbaric and time-consuming plan of defense is just to monitor visitor statistics for those obvious patterns of abuse and either ban the ips or range of ips accordingly. Aside from that, I don't know much else I could do to prevent all of the ping pong going on all day. Are there any good tools that automatically monitor this background activity (specifically activity that throws errors on the web & db server) and proactively deal with these source(s) of mayhem?

  • Why doesn't the monitor output anything in Linux console mode?

    - by flypen
    I install Linux without graphics support. Previously I used a monitor with 720p support. And it can display normally. Now I change to a monitor with 1080p support. I can see BIOS and GRUB info on monitor, and kernel messages in early stages. However, the monitor says that there is no input immediately, and then I can't see anything again. It seems that it happens after something initializes. Is it related to vesafb? vesafb: mode is 1280x1024x32, linelength=5120, pages=0 vesafb: scrolling: redraw vesafb: Truecolor: size=8:8:8:8, shift=24:16:8:0 mtrr: type mismatch for 7f800000,800000 old: write-back new: write-combining mtrr: type mismatch for 7f800000,400000 old: write-back new: write-combining mtrr: type mismatch for 7f800000,200000 old: write-back new: write-combining mtrr: type mismatch for 7f800000,100000 old: write-back new: write-combining mtrr: type mismatch for 7f800000,80000 old: write-back new: write-combining mtrr: type mismatch for 7f800000,40000 old: write-back new: write-combining mtrr: type mismatch for 7f800000,20000 old: write-back new: write-combining mtrr: type mismatch for 7f800000,10000 old: write-back new: write-combining mtrr: type mismatch for 7f800000,8000 old: write-back new: write-combining mtrr: type mismatch for 7f800000,4000 old: write-back new: write-combining mtrr: type mismatch for 7f800000,2000 old: write-back new: write-combining mtrr: type mismatch for 7f800000,1000 old: write-back new: write-combining vesafb: framebuffer at 0x7f800000, mapped to 0xffffc90011380000, using 5120k, total 5120k Console: switching to colour frame buffer device 160x64 fb0: VESA VGA frame buffer device
