  • postgresql table for storing automation test results

    - by Martin
    I am building an automation test suite which is running on multiple machines, all reporting their status to a postgresql database. We will run a number of automated tests for which we will store the following information: test ID (a GUID) test name test description status (running, done, waiting to be run) progress (%) start time of test end time of test test result latest screenshot of the running test (updated every 30 seconds) The number of tests isn't huge (say a few thousands) and each machine (say, 50 of them) have a service which checks the database and figures out if it's time to start a new automated test on that machine. How should I organize my SQL table to store all the information? Is a single table with a column per attribute the way to go? If in the future I need to add attributes but want to keep compatibility with old database format (ie I may not want to delete and create a new table with more columns), how should I proceed? Should the new attributes just be in a different table? I'm also thinking of replicating the database. In case of failure, I don't mind if the latest screenshots aren't backed up on the slave database. Should I just store the screenshots in its own table to simplify the replication? Thanks!

  • quartz.net - Can I not add a callback delegate method to JobExecutionContext?

    - by Greg
    Hi, BACKGROUND - I have a synchroisation function within my MainForm class. It gets called manually when the user pushes the SYNC button. I want to also call this synchroisation function when the scheduler triggers too, so effectively want SchedulerJob:IJob.Execute() method to be able to call it. QUESTION - How do I access the MainForm.Sychronization() method from within the SchedulerJob:IJob.Execute() method? I tried creating a delegate for this method in the MainForm class and getting it added via jobDetail.JobDataMap. However when I try I'm not sure that JobDataMap has a method to pull out a Delegate type??? private void Schedule(MainForm.SyncDelegate _syncNow) { var jobDetail = new JobDetail("MainJob", null, typeof(SchedulerJob)); jobDetail.JobDataMap["CallbackMethod"] = _syncNow; // Trigger Setup var trigger = new CronTrigger("MainTrigger"); string expression = GetCronExpression(); trigger.CronExpressionString = expression; trigger.StartTimeUtc = DateTime.Now.ToUniversalTime(); // Schedule Job & Trigger _scheduler.ScheduleJob(jobDetail, trigger); } public class SchedulerJob : IJob { public SchedulerJob() { } public void Execute(JobExecutionContext context) { JobDataMap dataMap = context.JobDetail.JobDataMap; MainForm.SyncDelegate CallbackFunction = dataMap.getDelegate["CallbackMethod"]; **// THIS METHOD DOESN'T EXIST - getDelegate()** CallbackFunction(); } } thanks

  • SQL 2000 (MSDE) Hangs When It Receives an Erroneous Query from a Classic ASP Web Application

    - by Jimbo
    I have a SQL interface page in my classic ASP web app that allows admin users to run queries against the app's database (MSDE 2000) - it simply consists of a textarea that the user submits and the app returns the resulting list of records as below Dim oRS Set oRS = Server.CreateObject("ADODB.Recordset") oRS.ActiveConnection = sConnectionString // run the query - this is for the admin only so doesnt check for sql safe commands etc. oRS.Open Request.Form("txtSQL") If Not oRS.EOF Then // list the field names from the recordset For i = 0 to oRS.Fields.Count - 1 Response.Write oRS.Fields(i).name & "&nbsp;" Next // show the data for each record in the recordset While Not oRS.EOF For i = 0 to oRS.Fields.Count - 1 Response.Write oRS.Fields(i).value & "&nbsp;" Next Response.Write "<br />" oRS.Movenext() Wend End If The problem with this is that if you send it an invalid query (with a spelling mistake, invalid join etc.) instead of throwing back an error immediately, it hangs IIS (you can see this by trying to browse the app from another computer, it fails) for a number of minutes and THEN returns the error. I have NO idea why! Can anyone help?

  • How to read an IIS 6 Website's Directory Structure using WMI?

    - by Steve Johnson
    I need to read a website's folders using WMI and C# in IIS 6.0. I am able to read the Virtual directories and applications using the "IISWebVirtualDirSetting" class. However the physical folders located inside a website cannot be read using this class. And for my case i need to read sub folders located within a website and later on set permission on them. For my requirement i dont need to work on Virtual Directories/Web Service Applications (which can be easily obtained using the code below..). I have tried to use IISWebDirectory class but it has been useful. Here is the code that reads IIS Virtual Directories... public static ArrayList RetrieveVirtualDirList(String ServerName, String WebsiteName) { ConnectionOptions options = SetUpAuthorization(); ManagementScope scope = new ManagementScope(string.Format(@"\\{0}\root\MicrosoftIISV2", ServerName), options); scope.Connect(); String SiteId = GetSiteIDFromSiteName(ServerName, WebsiteName); ObjectQuery OQuery = new ObjectQuery(@"SELECT * FROM IISWebVirtualDirSetting"); //ObjectQuery OQuery = new ObjectQuery(@"SELECT * FROM IIsSetting"); ManagementObjectSearcher WebSiteFinder = new ManagementObjectSearcher(scope, OQuery); ArrayList WebSiteListArray = new ArrayList(); ManagementObjectCollection WebSitesCollection = WebSiteFinder.Get(); String WebSiteName = String.Empty; foreach (ManagementObject WebSite in WebSitesCollection) { WebSiteName = WebSite.Properties["Name"].Value.ToString(); WebsiteName = WebSiteName.Replace("W3SVC/", ""); String extrctedSiteId = WebsiteName.Substring(0, WebsiteName.IndexOf('/')); String temp = WebsiteName.Substring(0, WebsiteName.IndexOf('/') + 1); String VirtualDirName = WebsiteName.Substring(temp.Length); WebsiteName = WebsiteName.Replace(SiteId, ""); if (extrctedSiteId.Equals(SiteId)) //if (true) { WebSiteListArray.Add(VirtualDirName ); //WebSiteListArray.Add(WebSiteName); //+ "|" + WebSite.Properties["Path"].Value.ToString() } } return WebSiteListArray; } P.S: I need to programmatically get the sub folders of an already deployed site(s) using WMI and C# in an ASP. Net Application. I need to find out the sub folders of existing websites in a local or remote IIS 6.0 Web Server. So i require a programmatic solution. Precisely if i am pointed at the right class (like IISWebVirtualDirSetting etc ) that i may use for retrieving the list of physical folders within a website then it will be quite helpful. I am not working in Powershell and i don't really need a solution that involves powershell or vbscripts. Any alternative programmatic way of doing the same in C#/ASP.Net will also be highly appreciated.

  • How do I lookup a JNDI Datasource from outside a web container?

    - by masotime
    I have the following environment set up: Java 1.5 Sun Application Server 8.2 Oracle 10 XE Struts 2 Hibernate I'm interested to know how I can write code for a Java client (i.e. outside of a web application) that can reference the JNDI datasource provided by the application server. The ports for the Sun Application Server are all at their defaults. There is a JNDI datasource named jdbc/xxxx in the server configuration, but I noticed that the Hibernate configuration for the web application uses the name java:comp/env/jdbc/xxxx instead. Most of the examples I've seen so far involve code like Context ctx = new InitialContext(); ctx.lookup("jdbc/xxxx"); But it seems I'm either using the wrong JNDI name, or I need to configure a jndi.properties or other configuration file to correctly point to a listener? I have appserv-rt.jar from the Sun Application Server which has a jndi.properties inside of it, but it does not seem to help. There's a similar question here, but it doesn't give any code / refers to having iBatis obtain the JNDI Datasource automatically: http://stackoverflow.com/questions/39053/accessing-datasource-from-outside-a-web-container-through-jndi

  • How do i bind an image to a <asp:Image /> tag in Form View

    - by Ranhiru
    First i have a getProfileImage.aspx which accepts a CusID and TN as query strings and display n image. So getProfileImage.aspx?CusID=10&TN=Y will show the image fine in the browser :) But... Now i am presented with a Form View and i want to bind the src of the image to get the image from the getProfileImage.aspx page... The following code works fine :) 10 is the customer ID and the image is working fine... <asp:Image ID="Image1" runat="server" Height="151px" ImageUrl='~/getProfileImage.aspx?CusID=10&TN=N' /> But now i want to Bind the CusID value... <asp:Image ID="Image1" runat="server" Height="151px" ImageUrl='~/getProfileImage.aspx?CusID=<%# Bind("CusID") %>&TN=N' /> This simply does not work :( The getProfileImage.aspx is called with CusID=<%... where the way i see it the <%# Bind("CusID") % is not parsed by ASP which would have returned 10... <%# Bind("CusID") %> The above tag alone will work... but inserting it to the middle of the tag seems to break it... Any suggestions ? Thanx a lot in advance :)

  • How can I print a web page on a server?

    - by Gavin Schultz
    Suppose I develop a web page using the cool Google visualization API, and it does everything the user wants. They can the parameters, look at the graphs, and print the page to get a reasonable-looking report. All good. Now suppose I want to do the same thing server-side. For example, say we need a set of report generated at a specific time of day, printed to a PDF and emailed to a manager. It's not a user-initiated action, so we don't have a user's browser or their printer. We have a URL that would render the report if we had a browser, and that's it. Is there a good way to do this server-side? Is this just foolish? Has anyone done anything like that before? Do any of the major browsers have APIs that might provide such functionality? Keep in mind too that it's not just static HTML; probably javascript will be running first to shift the DOM around. I know we could implement a whole different reporting engine on the server side to do this, but that will (a) generate reports that look a bit different, and (b) require me to build/maintain two sets of functionality. Instead, I'd be happy if I could just render the page / pages I want in an invisible server-side browser and print it to a PDF (let's mostly ignore that step - I know any number of PDF printer drivers that could do this). I don't really want to do it ugly either - i.e. by starting a browser process and then sending keystrokes directly to the window either - that's just bound to fall apart with a slight nudge. The only related question I found had an answer like that. Any advice appreciated!

  • insert BibTeX article *here*, not at the end of the article

    - by vy32
    I've seen this before, but I just can't find it. I am writing a resume and want to include the articles from my bibtex file. If I write \cite{FOO} then they all appear at the end. I know that there is some way to say \something{FOO} and the FOO reference appears here. Basically, I want this section of my CV to look like: \something{FOO1} \something{FOO2} What is the \something? Thanks.

  • Static methods and their overriding

    - by abson
    Java doesn't allow overriding of static methods but, class stat13 { static void show() { System.out.println("Static in base"); } public static void main(String[] ar) { new next().show(); } } class next extends stat13 { static void show() { System.out.println("Static in derived"); } } is not overriding done here?

  • Debugging problems in Visual Studio 2005 - No source code available for the current location

    - by espais
    Hi all I've searched up and down Google for others with a similar problem, and while I can find the error I don't think that other people have the same base problem that I do. Basically, I had to create a project for a unit-testing environment in order to run this test suite. First, I add my original C file, compile, and then a test file (C++) is generated. I then exclude my original source from the project, include this test script (which includes the original source at the top), and then run. I can debug the test file fine, but when it jumps to the original C file I get the dreaded 'no source code available for the current location' error. Both files are located within the same location, and I compiled the original file without any issue. Anybody have any thoughts about this? Its driving me crazy!

  • Preventing Processes From Spawning Using .NET Code

    - by Matt
    I remember coming across an article on I think CodeProject quite some time ago regarding an antivirus or antimalware some guy was writing where he hooked into the Windows API to be able to catch whenever a new process was started and was prompting he user before allowing the process to start. I can no longer find the article, and would actually like to be able to implement something like this. Currently, we have a custom browser built on Gecko that we've integrated access restrictions to sites based on our internal employee security levels, etc. We prevent any other browser from running with a timer and a call to Process.GetProcessesByName() from a list of the browsers we don't allow. What we want to accomplish is, instead of just blocking these browsers, where there is a small delay between the other browser starting and it being killed by our service, we'd like to be able to display a dialog instead of the process launching at all, explaining that the program isn't in the allowed list. This way, we can generate a list of "allowed" processes and just block everything else (we haven't yet had a problem with outside apps being installed, but you can never be too careful). Unfortunately, we don't do much Windows API programming from C#, so I'm not sure where to begin looking for what calls we need to hook. Even just a starting point of what to read up on would be helpful.

  • NSString copy not copying?

    - by Scotty Allen
    NSString *myString = @"sample string"; NSString *newString = [NSString stringWithString: myString]; If I set a breakpoint after these two lines, the pointer for myString is the same as the pointer for newString. WTF? Isn't NSString copy supposed to return a pointer to a new object? Or am I missing something fundamental about how copy is supposed to work?

  • No postback on any button click on ASP.NET 4.0 application

    - by Ashish Gupta
    The weird thing is If there is a javascript onClick() on a button, postback works otherwise, there is no postback. This was working very recently. I am not sure what recent changes made to the application made this happening throughout the site. The solution suggested by this link does not work as well (that link is applicable to .NET 1.1 though). Any idea whats going on?

    Hi, If I have a superclass, say Animal, and two subclasses: Zebra and Giraffe, If I decide to define a Vector of Animals: Vector <Animal> animals = new Vector(); and I want to say: You can add Giraffes, but you must own at least one Zebra first. What is the best way to do this without using RTTI? (instanceof)
