  • Windows 7 100% Memory Usage (without any process listed as using that much memory)

    - by Paul Tarjan
    When I plug my external USB 2TB hard drive into my windows 7 box, my RAM usage climbs up to all 4 Gigs (but in task manager it shows that all process are small) and the hard drive is churning like crazy. My CPU is only about 20% utilized All I can think of is there is a Virus scanner or an indexer running like crazy. I've tried to kill all virus scanners (AVG and Windows Security Essentials) and it still keeps going. My computer is completely unusable as everything is constantly swapping. I've tried leaving it on for 2 days now and it still hasn't finished whatever it was doing. Any ideas?

    - by Mark
    There are lots of tools for creating RAM drives. None of them seem to work for windows 2008 R2. Does anyone know if this is possible and if so how. Does anyone know of a tool that does work?

Any ideas? Thanks

  • [LINQ] Master&ndash;Detail Same Record (I)

    - by JTorrecilla
    PROBLEM Firstly, I am working on a project based on LINQ, EF, and C# with VS2010. The following Table shows what I have and what I want to show. Header C1 C2 C3 1 P1 01/01/2011 2 P2 01/02/2011 Details 1 1 D1 2 1 D2 3 1 D3 4 2 D1 5 2 D4 Expected Results 1 P1 01/01/2011 D1, D2, D3 2 P2 01/02/2011 D1,D4   IDEAS At the begin I got 3 possible ways: - Doing inside the DB:  It could be achieved from DB with a CURSOR in a Stored Procedure. - Doing from .NET with LOOPS. - Doing with LINQ (I love it!!) FIRST APROX Example with a simple CLASS with a LIST: With and Employee Class that acts as Header Table: 1: public class Employee 2: { 3: public Employee () { } 4: public Int32 ID { get; set; } 5: public String FirstName{ get; set; } 6: public String LastName{ get; set; } 7: public List<string> Numbers{ get; set; } // Acts as Details Table 8: } We can show all numbers contained by Employee: 1: List<Employee > listado = new List<Employee >(); 2: //Fill Listado 3: var query= from Employee em in listado 4: let Nums= string.Join(";", em.Numbers) 5: select new { 6: em.Name, 7: Nums 8: }; The “LET” operator allows us to host the results of “Join” of the Numbers List of the Employee Class. A little example. ASAP I will post the second part to achieve the same with Entity Framework. Best Regards

  • ORA-00900 Super Easy Fix (for some cases)

    - by Bunch
    Here is a really easy fix for some ORA-00900 errors. Well at least the one I saw the other day. This was something that I did not come across when searching either. I found lots of other ideas on what the problem might be but not the fix. Since I am fairly new to PL/SQL (TSQL only for a long time) this one stumped me for a while. Until I asked someone and they saw the error in about two seconds. When using the Command Window to add a view I was receiving an ORA-00900 error. So I checked that everything the view was referencing was there and that the permissions looked OK. The code for the view was fairly simple and it ran just fine in a regular SQL Window. It ended up that the Command Window did not like the space I had between the list of items in the select before the from. Bad: col1,col2,                               <--- does not like the empty linefrom tblSomething Good: col1,col2,from tblSomething I will just chalk that up to my familiarity with PL/SQL.

  • Apache mod_rewrite not working properly on Mac OS X 10.6 (Snow Leopard)

    - by DashRantic
    Hello all, I'm trying to create a PHP website with clean URLs with Apache's mod_rewrite, using a .htaccess file. mod_rewrite seems to be working, however, it claims it cannot find files on my server that do exist. Just as a basic test, this is what my .htaccess file looks like at the moment--going to [mysite]/page should redirect to the index.php file: Options +FollowSymLinks RewriteEngine on RewriteRule ^page$ index.php Afaik, I have setup the .conf file appropriately as well: <Directory "/Users/myuser/Sites/"> Options Indexes MultiViews AllowOverride All Order allow,deny Allow from all </Directory> However, when I try accessing the URL setup via mod_rewrite ( localhost/~myuser/mysite/page ), I get this: Not Found The requested URL /Users/myuser/Sites/mysite/index.php was not found on this server. However, that file does exist, and that is the proper location! The site works fine otherwise, if I go to localhost/~myuser/mysite/index.php, everything works fine--minus any sort of clean URLs, of course. Has anyone seen this before/have any ideas as to what I'm doing wrong?

  • Why does the terminal in unity 2d (Ubuntu 11.10) always stay in the foreground?

    - by user32509
    I have just updated to Ubuntu 11.10 and I am using unity 2d. My terminal applications (gnome-terminal or konsole) just won't go into background. When I move another application in front of them, they are still rendered, but the clicks are going through them. This behavior only appears when the terminal windows interact with another applications. I can move one terminal over another without a problem, but even the menu list of a terminal application can not be shown, since it is - for some unknown reason - "behind" the terminal. Any ideas what might be the cause of this problem? I do not have this problem with my other machines. The only difference is, that I am using unity 2d here and ("normal") unity at home.

  • CentOS running inside VMware as WebServer times out on outside connection [migrated]

    - by Tom Hart
    I have a CentOS machine running inside VMware, and I have got PHP and Apache set up on it, so if I open a browser (on the VM) and go to either localhost, or 192.168.0.3, I get a phpinfo page I made in /var/www/html/index.php, but, if on the host (Windows 7), in my browser I go to 192.168.0.3, it times out. I can ping the IP address from Windows and get a response, I just can't through the browser. Does anyone have any ideas what I need to do to get this working? This is my first time using a VM and I'm getting lost in the network settings.

  • What is the fastest way for me to become a full stack developer? [on hold]

    - by user136368
    I run a small webdesign firm. I have an overview of HTML, CSS, JS, PHP(laravel), MySQL. I did a few courses on code academy. I wanted to build a web app in the company. I find that I am severely crippled by the lack of programming expertise. I want to become a full stack developer who can build a prototype on his own. I cannot spend 5-10k USD on the boot camp courses. Can someone suggest structured courses which can help me become a full stack developers? I found the following websites but I donot know if they can help me become one. My goal: Be able to make a working prototype of the ideas I come up with.(This is my primary goal. I do not want to be the lead developer. I just want to be able to make a prototype.) Several questions I have in mind: Will it be fine if I stick to PHP(laravel)? Should I be using ROR? I have come across a few online resources: Codeacademy, codeschool,teamtreehouse,and theodinproject. These are within my affordability range. I can commit to a 2-3 months intensively to learn programming. What do you suggest I do?

  • Server IP must be a LAN IP (Port Forwarding Netgear Router)? [closed]

    - by rphello101
    I'm trying to set up a server (Apache) on my computer (fairly new to it). As I understand it, for it to be accessible to other computers, I need to forward port 80. When I try to forward the port though, I get the error: Server IP must be a LAN IP. I noticed in ipconfig that my default gateway is different than my wireless router. My computer is not hardwired, not on WiFi. Furthermore, I do not, at this point, have a static IP. I read that it should still work with a dynamic IP until it changes. Any ideas on what I can do? I'm using Windows 7 in case it matters.

  • How do I fix the Dash search not being able to find "additional drivers" nor "update"?

    - by Dronz
    I am a fairly new user of Ubuntu, and currently have two 12.04 installations, one of which seems to work ok but I have two problems. The problem I'm asking about in this question, is that the Dash search seems unable to find things, such as "additional drivers" or "update". On my working machine, searching for "additional drivers" there finds an icon for the driver program, but on the problem machine, it gives "Sorry, there is nothing that matches your search." Dash also only shows sections for Recent Files, and Downloads, on that machine. The account I'm running is an admin account. This installation also has a stuck Ubuntu Software Center (it loads and hangs) as in threads like this one. I don't think I've done very much to this computer that could cause a problem. I installed g++ and Wt to do some programming. The biggest change I can remember is uninstalling the newfangled scrollbars with "sudo apt-get remove liboverlay-scrollbar3-0.2-0", but re-installing that module seems to have no effect on these issues. Anyone have any ideas? Both machines have been updated with all recommended updates and say they are up to date.

  • VLAN help on ESX 4/vSphere

    - by user49032
    I setup a new VLAN with ID 153 in vSphere for my ESX4 server. The VLAN is setup for virtual machines and then I added a new NIC to the VM I want to be able to access the VM. The NIC is added to VLAN 153, but yet I am unable to ping the VLAN .1 IP that is setup on our Cisco 3750. The IP is properly setup on the Cisco 3750 because I'm able to ping the interface IP from other machines on the network. I'm guessing there must be an issue with the cabling. Any ideas?

  • Website project takes a long time to load in VS.NET 2008

    - by rm
    After getting a new computer (a lot faster than the one I've used before) my Solutions take A LONG TIME (3-4 minutes) to load up in VS.NET 2008. I only have 2 projects in the solution: DB Project and Website Project (from IIS). If I remove the Website Project from Solution - it loads up instantly, when I add that same website project to the OPEN Solution - it loads up instantly. The only time it's slow is when I open the solution referencing my Website project. I had the exact same setup (as far as VS is concerned) on my old box, and never had this problem. Any ideas?

  • Upgrading Apache, PHP and MySQL

    - by Javacadabra
    I'm looking to upgrade my current version of Apache, PHP and mySQL. I remember when I installed them it was a very intricate and somewhat delicate process and I am sort of afraid to upgrade in case everything just stops working! Currently I am running Apache 2.2.21 and PHP 5.3.5. MySQL is 5.6.4 Does anyone have any ideas how you upgrade these things? I think the current versions are Apache 2.4.3, PHP 5.4.7 and MySQL 5.6. Thanks in advance!

  • RDC stops working after a period of time.

    - by xjerx
    I have a workstation with RDC configured for the employee. When they leave at the end of their day they lock the pc (windows key + l). They go home connect to our VPN and log back in. Everything works fine. The following morning they will attempt to log in before they return to the office. The computer does not respond to the RDC request. I've found that it becomes completely inactive to any ICMP requests. Once the user reboots the computer everything works fine again. I'm going to turn off RDC, reboot, turn RDC back on and reboot again to see if it fixes the problem. Until then does anyone have any other ideas?

  • Installshield Development Error durring the Installation process

    - by Alopekos
    Hey guys, I've been stuck by a problem for the past couple days that makes no sense to me. My installer builds fine in the Installshiled IDE but when it is about to finish the installation, int gets two errors then rollbacks: installation failure. Right when the install bar is at about 100%, an error box pops up that states this: "Error 1001.Exception occurred while initializing the installation: System.IO.FileLoadException: Attempt to load an unverifiable executable with fixups (IAT with more than 2 sections or a TLS section.) (Exception from HRESULT: 0x80131019)." The box pops up once, then the installer flashes its status to "rollback" then pops up another error box, then once 'ok'ed it procedes to rollback as usual. I don't understand that error message so i looked in the msi loggings and found this: "InstallShield 13:20:08: Initializing Property Bag...

Is this a registering command system that makes it attemp or what? I've been scouring the web all day and I've found some ideas, but I havent seen any solutions as of yet. The installers that I've tried(and failed) have always needed to be Setup.exes, when i try to build a .msi only setup I get this error message. It may help someone who knows more about this system than I do. Your project contains InstallShield prerequisites. A Setup.exe setup launcher is required if you are build a release that includes InstallShield prerequisites. Change your release settings to build Setup.exe, or remove the prerequisites from your project. -7076 There's nothing on the site that has anything from the error code, so I'm at a loss. Thanks for any help possible, I'm an intern and I'm fresh out of ideas... Josh System: XP SP3 Installshield 2010 Pro Install being tested on a VirtualPC

  • Stumped by "The remote server returned an error: (403) Forbidden" with WCF Service in https

    - by RJ
    I have a WCF Service that I have boiled down to next to nothing because of this error. It is driving me up the wall. Here's what I have now. A very simple WCF service with one method that returns a string with the value, "test". A very simple Web app that uses the service and puts the value of the string into a label. A web server running IIS 6 on Win 2003 with a SSL certificate. Other WCF services on the same server that work. I publish the WCF service to it's https location I run the web app in debug mode in VS and it works perfectly. I publish the web app to it's https location on the same server the WCF service resides under the same SSL certificate I get, "The remote server returned an error: (403) Forbidden" I have changed almost every setting in IIS as well as the WCF and Web apps to no avail. I have compared setting in the WCF services that work and everything is the same. Below are the setting in the web.config for the WCF Service and the WEB app: It appears the problem has to do with the Web app but I am out of ideas. Any ideas: WCF Service: <system.serviceModel> <bindings> <client /> <services> <service behaviorConfiguration="Ucf.Smtp.Wcf.SmtpServiceBehavior" name="Ucf.Smtp.Wcf.SmtpService"> <host> <baseAddresses> <add baseAddress="https://test.net.ucf.edu/webservices/Smtp/" /> </baseAddresses> </host> <endpoint address="" binding="wsHttpBinding" contract="Ucf.Smtp.Wcf.ISmtpService" bindingConfiguration="SSLBinding"> <identity> <dns value="localhost"/> </identity> </endpoint> <endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange"/> </service> </services> <behaviors> <serviceBehaviors> <behavior name="Ucf.Smtp.Wcf.SmtpServiceBehavior"> <serviceMetadata httpsGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="true" httpsHelpPageEnabled="True"/> </behavior> </serviceBehaviors> </behaviors> Web App: <system.serviceModel> <bindings><wsHttpBinding> <binding name="WSHttpBinding_ISmtpService" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" /> <security mode="Transport"> <transport clientCredentialType="None" proxyCredentialType="None" realm="" /> <message clientCredentialType="Windows" negotiateServiceCredential="true" establishSecurityContext="true" /> </security> </binding> <client> <endpoint address="https://net228.net.ucf.edu/webservices/smtp/SmtpService.svc" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_ISmtpService" contract="SmtpService.ISmtpService" name="WSHttpBinding_ISmtpService"> <identity> <dns value="localhost" /> </identity> </client> </system.serviceModel>

  • Microsoft SyncFramework - Sync different tables into one

    - by evnu
    Hello, we are trying to get the Microsoft SyncFramework running in our application to synchronize an oracle db with a mobile device. Problem The queries that we need to gather the data on the oracle db take much time (and we haven't found a way to speed them up yet), so we try to split them up in as much portions as possible. One big part of the whole problem is, that we need different information out of one big table, that bloats a query if combined. Unfortunately, the SyncFramework allows only one TableAdapter per SyncTable. Now this is a problem for our application: If we were able to use more than one TableAdapter per SyncTable, we could easily spread the queries in a more efficient way. Using one query per Table which combines all the needed data takes way too much time. Ideas I thought of creating different TableAdapters for each one of the required queries and then merge the resulting datasets afterwards (preferably on the server). This seems to work, but is a rather awkward solution. Does someone of you know a better solution? Or do you have some ideas that could help? Thanks in advance, evnu EDIT: So, I implemented the merge solution. If you are interested, take a look at the following code. I'll give more details if there are questions. <WebMethod()> _ Public Function GetChanges(ByVal groupMetadata As SyncGroupMetadata, ByVal syncSession As SyncSession) As SyncContext Dim stream As MemoryStream Dim format As BinaryFormatter = New BinaryFormatter Dim anchors As Dictionary(Of String, Byte()) ' keep track of the tables that will be updated Dim addTables As Dictionary(Of String, List(Of SyncTableMetadata)) = New Dictionary(Of String, List(Of SyncTableMetadata)) ' list of all present anchors Dim allAnchors As Dictionary(Of String, Byte()) = New Dictionary(Of String, Byte()) ' fill allAnchors - deserialize all given anchors For Each Table As SyncTableMetadata In groupMetadata.TablesMetadata If Table.LastReceivedAnchor Is Nothing Or Table.LastReceivedAnchor.IsNull Then Continue For stream = New MemoryStream(Table.LastReceivedAnchor.Anchor) anchors = format.Deserialize(stream) For Each item As KeyValuePair(Of String, Byte()) In anchors allAnchors.Add(item.Key, item.Value) Next stream.Dispose() Next For Each Table As SyncTableMetadata In groupMetadata.TablesMetadata If allAnchors.ContainsKey(Table.TableName) Then Table.LastReceivedAnchor.Anchor = allAnchors(Table.TableName) End If Dim addSyncTables As List(Of SyncTableMetadata) If syncSession.SyncParameters.Contains(Table.TableName) Then Dim tableNames() As String = syncSession.SyncParameters(Table.TableName).Value.ToString.Split(":") addSyncTables = New List(Of SyncTableMetadata) For Each tableName As String In tableNames Dim newSynctable As SyncTableMetadata = New SyncTableMetadata newSynctable.TableName = tableName If allAnchors.ContainsKey(tableName) Then Dim anker As SyncAnchor = New SyncAnchor(allAnchors(tableName)) newSynctable.LastReceivedAnchor = anker Else newSynctable.LastReceivedAnchor = Nothing End If newSynctable.SyncDirection = Table.SyncDirection addSyncTables.Add(newSynctable) Next addTables.Add(Table.TableName, addSyncTables) End If Next ' add the newly created synctables For Each item As KeyValuePair(Of String, List(Of SyncTableMetadata)) In addTables For Each Table As SyncTableMetadata In item.Value groupMetadata.TablesMetadata.Add(Table) Next Next ' fire queries Dim context As SyncContext = servSyncProvider.GetChanges(groupMetadata, syncSession) ' merge resulting datasets For Each item As KeyValuePair(Of String, List(Of SyncTableMetadata)) In addTables For Each Table As SyncTableMetadata In item.Value If context.DataSet.Tables.Contains(Table.TableName) Then If Not context.DataSet.Tables.Contains(item.Key) Then Dim tmp As DataTable = context.DataSet.Tables(Table.TableName).Copy tmp.TableName = item.Key context.DataSet.Tables.Add(tmp) Else context.DataSet.Tables(item.Key).Merge(context.DataSet.Tables(Table.TableName)) context.DataSet.Tables.Remove(Table.TableName) End If End If Next Next ' create new anchors Dim allAnchorsDict As Dictionary(Of String, Byte()) = New Dictionary(Of String, Byte()) For Each Table As SyncTableMetadata In groupMetadata.TablesMetadata allAnchorsDict.Add(Table.TableName, context.NewAnchor.Anchor) Next stream = New MemoryStream format.Serialize(stream, allAnchorsDict) context.NewAnchor.Anchor = stream.ToArray stream.Dispose() Return context End Function

  • Summer Programming Plans

    - by Gabe
    I've wanted to start "hacking" for many months now. But I put it off in favor of school and other things. Now, though, I'm free for the summer and want to learn as much as I can. I have a rough idea of what I want to try my hand at, but need some guidance as to what specifically - and how - I should learn. This is my plan so far: 1) Get good at programming in general. I plan to read up on how to think/work like a programmer. I'm waiting for the Pragmatic Programmer to arrive, which will be the first book I read. Q: What other books/ebooks should I look at? What more can I do here? 2) Learn/Improve at HTML/CSS. My first project will be to make a personal website/blog for myself using HTML and CSS. ----Then I hope to write/design articles like Dustin Curtis. After I finish this (and learn a programming language) I'll try to create user-based a user-focused website. Q: It's my understanding that just trying to design/manage websites is a good way to learn/improve at HTML/CSS. Is that all correct? 3) Try music development. This might be a sort of stretch for stackoverflow, but I'm interested in mixing/making techno songs. (Think Justice, or Daft Punk, or MSTRKRFT.) Q: I have a Mac. Any ideas on how I could start/learn music making? Any programs I should download, for instance? 4) My main goal: Learning a web development language/framework. I'm a year into learning/using C++. But what I really want to do is develop websites and web apps. I've searched online, and there seems to be great debate over which language/framework to learn first (and which is best). I think I've narrowed it down to three: Ruby (Rails), Python (Django), and PHP (?). Q #1: Which should I learn and use first? (Reasons?) Q #2: One reason I was leaning towards PHP is that I'm taking a PHP development course next semester. Learning it now would make that course easy. If PHP was not the answer to Q #1, is it worth learning both? Or, would it be better to just focus on PHP for this summer and next semester, and then transition thereafter to a better language? 5) iPhone/iPad Programming (Maybe). I've a number of simple, useful app ideas that I'd like to eventually get too. I just bought a Mac, as well as a few app development books. Q #1: Am I spreading myself thin trying to learn all of the above, and objective-C? Q #2: How much harder/easier is objective-C compared to the above languages? Also, how easy is it to learn obj-C after learning a web development language (and some C++)? Q #3: Yes or no? Should I go for it, or just keeep with #1-4 for now? Also: If you have any tips on how I should learn (or how you learned to hack), I'm all ears. I'd be especially interested in how you planned out learning: did you just hack whenever you felt like it, or did you "study" the language a few hours a day, or something else? Thanks so much, guys.

  • Forms Authentication works on dev server but not production server (same SQL db)

    - by Desmond
    Hi, I have the same problem as a previously solved question however, this solution did not help me. I have posted the previous question and answer below: http://stackoverflow.com/questions/2215963/forms-authentication-works-on-dev-server-but-not-production-server-same-sql-db/2963985#2963985 Question: I've never had this problem before, I'm at a total loss. I have a SQL Server 2008 database with ASP.NET Forms Authentication, profiles and roles created and is functional on the development workstation. I can login using the created users without problem. I back up the database on the development computer and restore it on the production server. I xcopy the DLLs and ASP.NET files to the server. I make the necessary changes in the web.config, changing the SQL connection strings to point to the production server database and upload it. I've made sure to generate a machine key and it is the same on both the development web.config and the production web.config. And yet, when I try to login on the production server, the same user that I'm able to login successfully with on the development computer, fails on the production server. There is other content in the database, the schema generated by FluentNHibernate. This content is able to be queried successfully on both development and production servers. This is mind boggling, I believe I've verified everything, but obviously it is still not working and I must have missed something. Please, any ideas? Answer: I ran into a problem with similar symptoms at one point by forgetting to set the applicationName attribute in the web.config under the membership providers element. Users are associated to a specific application. Since I didn't set the applicationName, it defaulted to the application path (something like "/MyApplication"). When it was moved to production, the path changed (for example to "/WebSiteFolder/SomeSubFolder /MyApplication"), so the application name defaulted to the new production path and an association could not be made to the original user accounts that were set up in development. Could your issues possibly be the same as mine? I have this already in my web.config but still get the issue. Any ideas? <membership> <providers> <clear/> <add name="AspNetSqlMembershipProvider" type="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionStringName="ApplicationServices" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" passwordFormat="Hashed" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" passwordStrengthRegularExpression="" applicationName="/"/> </providers> </membership> <profile> <providers> <clear/> <add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionStringName="ApplicationServices" applicationName="/"/> </providers> </profile> <roleManager enabled="false"> <providers> <clear/> <add connectionStringName="ApplicationServices" applicationName="/" name="AspNetSqlRoleProvider" type="System.Web.Security.SqlRoleProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/> <add applicationName="/" name="AspNetWindowsTokenRoleProvider" type="System.Web.Security.WindowsTokenRoleProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/> </providers> </roleManager> Any help is greatly appriciated.

  • What is the coolest thing you can do in <10 lines of simple code? Help me inspire beginners!

    - by Tom Ritter
    I'm looking for the coolest thing you can do in a few lines of simple code. I'm sure you can write a Mandelbrot set in Haskell in 15 lines but it's difficult to follow. My goal is to inspire students that programming is cool. We know that programming is cool because you can create anything you imagine - it's the ultimate creative outlet. I want to inspire these beginners and get them over as many early-learning humps as I can. Now, my reasons are selfish. I'm teaching an Intro to Computing course to a group of 60 half-engineering, half business majors; all freshmen. They are the students who came from underprivileged High schools. From my past experience, the group is generally split as follows: a few rock-stars, some who try very hard and kind of get it, the few who try very hard and barely get it, and the few who don't care. I want to reach as many of these groups as effectively as I can. Here's an example of how I'd use a computer program to teach: Here's an example of what I'm looking for: a 1-line VBS script to get your computer to talk to you: CreateObject("sapi.spvoice").Speak InputBox("Enter your text","Talk it") I could use this to demonstrate order of operations. I'd show the code, let them play with it, then explain that There's a lot going on in that line, but the computer can make sense of it, because it knows the rules. Then I'd show them something like this: 4(5*5) / 10 + 9(.25 + .75) And you can see that first I need to do is (5*5). Then I can multiply for 4. And now I've created the Object. Dividing by 10 is the same as calling Speak - I can't Speak before I have an object, and I can't divide before I have 100. Then on the other side I first create an InputBox with some instructions for how to display it. When I hit enter on the input box it evaluates or "returns" whatever I entered. (Hint: 'oooooo' makes a funny sound) So when I say Speak, the right side is what to Speak. And I get that from the InputBox. So when you do several things on a line, like: x = 14 + y; You need to be aware of the order of things. First we add 14 and y. Then we put the result (what it evaluates to, or returns) into x. That's my goal, to have a bunch of these cool examples to demonstrate and teach the class while they have fun. I tried this example on my roommate and while I may not use this as the first lesson, she liked it and learned something. Some cool mathematica programs that make beautiful graphs or shapes that are easy to understand would be good ideas and I'm going to look into those. Here are some complicated actionscript examples but that's a bit too advanced and I can't teach flash. What other ideas do you have?

  • How do I launch a WPF app from command.com. I'm getting a FontCache error.

    - by jttraino
    I know this is not ideal, but my constraint is that I have a legacy application written in Clipper. I want to launch a new, WinForms/WPF application from inside the application (to ease transition). This legacy application written in Clipper launches using: SwpRunCmd("C:\MyApp\MyBat.bat",0) The batch file contains something like this command: C:\PROGRA~1\INTERN~1\iexplore "http://QASVR/MyApp/AppWin/MyCompany.MyApp.AppWin.application#MyCompany.MyApp.AppWin.application" It is launching a WinForms/WPF app that is we deploy via ClickOnce. Everything has been going well until we introduced WPF into the application. We were able to easily launch from the legacy application. Since we have introduced WPF, however, we have the following behavior. If we launch via the Clipper application first, we get an exception when launching the application. The error text is: The type initializer for 'System.Windows.FrameworkElement' threw an exception. at System.Windows.FrameworkElement..ctor() at System.Windows.Controls.Panel..ctor() at System.Windows.Controls.DockPanel..ctor() at System.Windows.Forms.Integration.AvalonAdapter..ctor(ElementHost hostControl) at System.Windows.Forms.Integration.ElementHost..ctor() at MyCompany.MyApp.AppWin.Main.InitializeComponent() at MyCompany.MyApp.AppWin.Main..ctor(String[] args) at MyCompany.MyApp.AppWin.Program.Main(String[] args) The type initializer for 'System.Windows.Documents.TextElement' threw an exception. at System.Windows.FrameworkElement..cctor() The type initializer for 'System.Windows.Media.FontFamily' threw an exception. at System.Windows.Media.FontFamily..ctor(String familyName) at System.Windows.SystemFonts.get_MessageFontFamily() at System.Windows.Documents.TextElement..cctor() The type initializer for 'MS.Internal.FontCache.Util' threw an exception. at MS.Internal.FontCache.Util.get_WindowsFontsUriObject() at System.Windows.Media.FontFamily.PreCreateDefaultFamilyCollection() at System.Windows.Media.FontFamily..cctor() Invalid URI: The format of the URI could not be determined. at System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind) at System.Uri..ctor(String uriString, UriKind uriKind) at MS.Internal.FontCache.Util..cctor() If we launch the application via the URL (in IE) or via the icon on the desktop first, we do not get the exception and application launches as expected. The neat thing is that whatever we launch with first determines whether the app will launch at all. So, if we launch with legacy first, it breaks right away and we can't get the app to run even if we launch with the otherwise successful URL or icon. To get it to work, we have to logout and log back in and start it from the URL or icon. If we first use the URL or the icon, we have no problem launching from the legacy application from that point forward (until we logout and come back in). One other piece of information is that we are able to simulate the problem in the following fashion. If we enter a command prompt using "cmd.exe" and execute a statement to launch from a URL, we are successful. If, however, we enter a command prompt using "command.com" and we execute that same statement, we experience the breaking behavior. We assume it is because the legacy application in Clipper uses the equivalent of command.com to create the shell to spawn the other app. We have tried a bunch of hacks like having command.com run cmd.exe or psexec and then executing, but nothing seems to work. We have some ideas for workarounds (like making the app launch on startup so we force the successful launch from a URL, making all subsequent launches successful), but they all are sub-optimal even though we have a great deal of control over our workstations. To reduce the chance that this is related to permissions, we have given the launching account administrative rights (as well as non-administrative rights in case that made a difference). Any ideas would be greatly-appreciate. Like I said, we have some work arounds, but I would love to avoid them. Thanks!

  • C++ template function specialization using TCHAR on Visual Studio 2005

    - by Eli
    I'm writing a logging class that uses a templatized operator<< function. I'm specializing the template function on wide-character string so that I can do some wide-to-narrow translation before writing the log message. I can't get TCHAR to work properly - it doesn't use the specialization. Ideas? Here's the pertinent code: // Log.h header class Log { public: template <typename T> Log& operator<<( const T& x ); template <typename T> Log& operator<<( const T* x ); template <typename T> Log& operator<<( const T*& x ); ... } template <typename T> Log& Log::operator<<( const T& input ) { printf("ref"); } template <typename T> Log& Log::operator<<( const T* input ) { printf("ptr"); } template <> Log& Log::operator<<( const std::wstring& input ); template <> Log& Log::operator<<( const wchar_t* input ); And the source file // Log.cpp template <> Log& Log::operator<<( const std::wstring& input ) { printf("wstring ref"); } template <> Log& Log::operator<<( const wchar_t* input ) { printf("wchar_t ptr"); } template <> Log& Log::operator<<( const TCHAR*& input ) { printf("tchar ptr ref"); } Now, I use the following test program to exercise these functions // main.cpp - test program int main() { Log log; log << "test 1"; log << L"test 2"; std::string test3( "test3" ); log << test3; std::wstring test4( L"test4" ); log << test4; TCHAR* test5 = L"test5"; log << test4; } Running the above tests reveals the following: // Test results ptr wchar_t ptr ref wstring ref ref Unfortunately, that's not quite right. I'd really like the last one to be "TCHAR", so that I can convert it. According to Visual Studio's debugger, the when I step in to the function being called in test 5, the type is wchar_t*& - but it's not calling the appropriate specialization. Ideas? I'm not sure if it's pertinent or not, but this is on a Windows CE 5.0 device.

  • Apache/PHP serving file multiple times

    - by easement
    I have a system with a download.php page. The page takes and id and loads a file based on from the DB Record and then serves it up. I've noticed a couple instances where files are requested multiple times in short time spans (20ms). Times that are too quick for human input. There are plenty of instances where the downloader functions fine. However, in taking a closer look at the downloader’s usage, I did see some interesting behavior. For instance, the IP address xxx.xxx.xxx.xxx (which is one in a range owned by xxxxxx.de in Germany) came to the site through Google. They browsed around and then came to the page http://site.com/xxxx/press+125.php There they issued a request for /download.php?id=/ZZ/n+aH55Y= (a PDF) at 9:04:23AM. That alone is not a big deal. However, what is interesting is that the server seems to have been quite preoccupied with serving that request. In the logs the request first completes between 9:09:48 and 9:10:00. It looks like the user must have gotten tired of waiting during that time and requested the document two more times. Between 09:14:47 and 09:15:00 the same request appears again, except it is from 9:04:43AM, 20ms later than the first request. Then it pops up a third time, with a request that started at 09:05:06 completing between 09:19:55 and 09:19:58! I’m suspicious of that document. In looking through the logs I see other instances where it takes the server a little while to handle that specific file. Check out this list of requests from zzz.zzz.zzz.zzz[different than above] for the file /download.php?id=/ZZ/n+aH55Y= (the same docuemnt as before): Request time Complete Time 04:32:43 04:33:36 04:32:50 04:33:36 04:32:51 04:33:38 04:33:05 04:33:38 04:33:34 04:33:42 04:33:05 04:33:42 So something is definitely going on. Whether it has to do with this specific document tripping up the server, the download.php page’s code, or if we’re just seeing the evidence of some server level overload as it plays out in real time I’m not yet sure. In fairness, there are other instances of people downloading /download.php?id=/ZZ/n+aH55Y= (the same PDF) without error. However, it is interesting that the multiple processes only seem to happen with this one file, and then only when it is accessed through the page http://site.com/press+125.php . It bears further investigation if there’s something amiss inside the code that causes the system to fire off multiple download requests that occupy the server. I don't know if this press+125.php is a rabbit hole, but there is weird consicence. Any ideas? I'm totally out of ideas. Apache maxed out? Things like that. ///DOWNLOAD.php $file = new files(); $file->comparison_filter("id", "=", $id); //sql to load if ($file->load()) { $file->serve(); } //FILES function serve() { if ($this->is_loaded) { if (file_exists($this->get_value("filename"))) { if ($this->get_value("content_type") != "") { header("Content-Type: " . $this->get_value("content_type")); } header("Content-Length: " . filesize($this->get_value("filename"))); if ($this->get_value("flag_image") == 0 || $this->get_value("flag_image") == false) { header("Cache-Control: private"); header("Content-Disposition: attachment; filename=" . urlencode($this->get_value("original_filename"))); } set_time_limit(0); @readfile($this->get_value("filename")); exit; } } }

  • Winforms controls and "generic" events handlers. How can I do this?

    - by Yanko Hernández Alvarez
    In the demo of the ObjectListView control there is this code (in the "Complex Example" tab page) to allow for a custom editor (a ComboBox) (Adapted to my case and edited for clarity): EventHandler CurrentEH; private void ObjectListView_CellEditStarting(object sender, CellEditEventArgs e) { if (e.Column == SomeCol) { ISomeInterface M = (e.RowObject as ObjectListView1Row).SomeObject; //(1) ComboBox cb = new ComboBox(); cb.Bounds = e.CellBounds; cb.DropDownStyle = ComboBoxStyle.DropDownList; cb.DataSource = ISomeOtherObjectCollection; cb.DisplayMember = "propertyName"; cb.DataBindings.Add("SelectedItem", M, "ISomeOtherObject", false, DataSourceUpdateMode.Never); e.Control = cb; cb.SelectedIndexChanged += CurrentEH = (object sender2, EventArgs e2) => M.ISomeOtherObject = (ISomeOtherObject)((ComboBox)sender2).SelectedValue; //(2) } } private void ObjectListView_CellEditFinishing(object sender, CellEditEventArgs e) { if (e.Column == SomeCol) { // Stop listening for change events ((ComboBox)e.Control).SelectedIndexChanged -= CurrentEH; // Any updating will have been down in the SelectedIndexChanged // event handler. // Here we simply make the list redraw the involved ListViewItem ((ObjectListView)sender).RefreshItem(e.ListViewItem); // We have updated the model object, so we cancel the auto update e.Cancel = true; } } I have too many other columns with combo editors inside objectlistviews to use a copy& paste strategy (besides, copy&paste is a serious source of bugs), so I tried to parameterize the code to keep the code duplication to a minimum. ObjectListView_CellEditFinishing is a piece of cake: HashSet<OLVColumn> cbColumns = new HashSet<OLVColumn> (new OLVColumn[] { SomeCol, SomeCol2, ...}; private void ObjectListView_CellEditFinishing(object sender, CellEditEventArgs e) { if (cbColumns.Contains(e.Column)) ... but ObjectListView_CellEditStarting is the problematic. I guess in CellEditStarting I will have to discriminate each case separately: private void ObjectListView_CellEditStarting(object sender, CellEditEventArgs e) { if (e.Column == SomeCol) // code to create the combo, put the correct list as the datasource, etc. else if (e.Column == SomeOtherCol) // code to create the combo, put the correct list as the datasource, etc. And so on. But how can I parameterize the "code to create the combo, put the correct list as the datasource, etc."? Problem lines are (1) Get SomeObject. the property NAME varies. (2) Set ISomeOtherObject, the property name varies too. The types vary too, but I can cover those cases with a generic method combined with a not so "typesafe" API (for instance, the cb.DataBindings.Add and cb.DataSource both use an object) Reflection? more lambdas? Any ideas? Any other way to do the same? PS: I want to be able to do something like this: private void ObjectListView_CellEditStarting(object sender, CellEditEventArgs e) { if (e.Column == SomeCol) SetUpCombo<ISomeInterface>(ISomeOtherObjectCollection, "propertyName", SomeObject, ISomeOtherObject); else if (e.Column == SomeOtherCol) SetUpCombo<ISomeInterface2>(ISomeOtherObject2Collection, "propertyName2", SomeObject2 ISomeOtherObject2); and so on. Or something like that. I know, parameters SomeObject and ISomeOtherObject are not real parameters per see, but you get the idea of what I want. I want not to repeat the same code skeleton again and again and again. One solution would be "preprocessor generics" like C's DEFINE, but I don't thing c# has something like that. So, does anyone have some alternate ideas to solve this?
