  • Run WF 4.0 as a server-side component

    - by user184216
    Hi all, For a new project, we need to use WF 4.0 for deploying and running workflows. Instead of hosting workflows within the application itself, we decided to implement a server-side component that is in charge of running workflows. Before WF 4.0, one had explicit access to the the runtime engine (WorkflowRuntime), which provided some basic management functionalities, such as retrieving the workflows currently running etc ... As far as I could find out, WF 4.0 lacks this explicit access, as workflows are created via the WorkflowInstance class and no reference is immediately available to the WorkflowRuntime ... If I need these management functionalities on the server side, I'm a correct that I will need to implement these myself? Or did I miss out on something ... Thanks in advance for your answers!

  • Tree View WIKI replacement solution for SharePoint like Confluence?

    - by Melih Öztürk
    Hi to all, I keep my Process Documents on SVN and I want to create a Wiki page includes the information about these files. We use SharePoint in the company for basic document sharing and team sites. As it is mentioned in http://stackoverflow.com/questions/256407/what-are-your-biggest-complaints-about-sharepoint SharePoint Wiki lacks of usability. I need an easy to use wiki tool which is capable of showing the content like WikiPedia contents and it would be great if I could have the SharePoint tree view and Active Directory authentication also. I googled it and found Atlassian's Confluence and it seems that this product is capable of the requirements. We use Jira for issue tracking, so we can use it's reporting in dashboards. I need and it has a Wiki part which displays wiki pages in tree view. It should be like Does anyone used Confluence or have an idea for other products which meets my requirements

  • Best way to split a string by word (SQL Batch separator)

    - by Paul Kohler
    I have a class I use to "split" a string of SQL commands by a batch separator - e.g. "GO" - into a list of SQL commands that are run in turn etc. ... private static IEnumerable<string> SplitByBatchIndecator(string script, string batchIndicator) { string pattern = string.Concat("^\\s*", batchIndicator, "\\s*$"); RegexOptions options = RegexOptions.Compiled | RegexOptions.IgnoreCase | RegexOptions.Multiline; foreach (string batch in Regex.Split(script, pattern, options)) { yield return batch.Trim(); } } My current implementation uses a Regex with yield but I am not sure if it's the "best" way. It should be quick It should handle large strings (I have some scripts that are 10mb in size for example) The hardest part (that the above code currently does not do) is to take quoted text into account Currently the following SQL will incorrectly get split: var batch = QueryBatch.Parse(@"-- issue... insert into table (name, desc) values('foo', 'if the go is on a line by itself we have a problem...')"); Assert.That(batch.Queries.Count, Is.EqualTo(1), "This fails for now..."); I have thought about a token based parser that tracks the state of the open closed quotes but am not sure if Regex will do it. Any ideas!?

  • Usage of open source libraries in high governance and risk-averse large organizations (banks, financ

    - by bart
    Does anyone have any good stories of these kinds of organizations being open to using open source dependencies (and also tools). Many staff I've encountered have little or no exposure to open source/systems and open source is treated with great suspicion. Some reasons given for this are lack of support and robustness, which is ironic given the number of end-of-life unsupported vendor products that are in production. I'm also interested in any success stories where you've seen open source go into orgs like this and have a real benefit!

  • Access Violation When Writing Dynamic 2D Array... Sometimes

    - by Shraptnel
    This program is meant to generate a dynamic array, however it gives an access violation error when writing when given certain dimensions. Eg: R = 6, C = 5 crashes, but then R = 5, C = 6 doesn't. In case your wondering, it isn't my homework to "fix" this broken program, this is the method we were taught in class. Also part of my assessment is to use this method, so vectors are out. Thanks in advance! #include <iostream> using namespace std; int main(){ const int R = 6; const int C = 5; char **d; d = new char *[R]; for(int i=0; i<C; ++i){ d[i] = new char[C]; } //initialise for(int i=0; i<R; ++i){ for(int j=0; j<C; ++j){ d[i][j] = 'd'; cout<<d[i][j]; } cout<<endl; } cout<<endl; system("pause"); return 0; }

  • Problem with setting up raid5 on Freenas, Please help.

    - by Benjy23
    Hey Guys, I've been running Freenas for awhile now. Hardware is 1.8celeron Ram 1GB Sata Card is Via - not sure the model.... its 2 ports and I have 6 x 1.5TB HDs All ran ok while running on 1.5TB, no raid. I'm now trying to create a raid5 with my 6 hds. Software raid... is it normal for it to take roughly up to 2 weeks just to build the raid? Sorry, I'm very new to implementing raid and googling doesn't tell much other than it takes a long time. Also the Raid building process seems to fail many times... going to degraded. I suspect its cos 4 of my HDs are connected to my motherboard and the other 2 are connected to my sata card...what's your take? I'm considering 2 options now... either get a 8 port sata card and attach all the HDs to it. Or get a raid controller 8 portcard which is probably gonna be more pricey... also how do you access hardware raid through Freenas? I like how Freenas emails you should your harddrive fails so can this be done as well with hardware raid? Thanks in advance guys.

  • Any worker agent monitors for appliance based load balancers?

    - by Zethris
    Looking to find out to what extent an appliance load balancer can monitor servers for both failover (say for example a service like apache tomcat fails) and load balancing? Right now it looks like it's just port monitoring/connection tracking and healthcheck urls that it will heartbeat and detect as down if it doesn't come back with a finished request. We are looking at the Kemp 3500 or Loadbalancer.org solutions. Is there any sort of web application level monitoring/load balancing that these load balancers can offer that can more directly interact with the servers it's balancing?

  • Removing SCIM input method as default from gnome terminal

    - by Mark
    Hello - I am recently back into the Linux world after about a 10 year absence. While I can find my way around most things, terminals and desktop managers are different than I remember. One of the biggest problems that I am encountering today is that when running a gnome terminal (this is Suse 10.0 enterprise), I'm getting behavior in the window that I don't want. Specifically, when I type, my typing is underlined as if something is trying to spell check my window. Further, it seems as if when running vi or less, my keystrokes are only processed by these apps when I hit 'return'. I.e. if I'm running less and want to go back a page, I'll hit b, but nothing happens until I hit 'return'. I seem to have tracked this down to the 'input method". Right clicking in the Gnome terminal allows me to set my input method to one of a dozen values. It seems that currently, it's set to "SCIM Input Method". If I then select 'default' or 'X Input Method', apps (i.e. things like less, vi, and even the bash shell) behave as I would expect. Can someone tell me a) what is this SCIM input method b) how can I make it so that it is not the default? I've poked around various configuration files in my home directory as well as in /etc, but I can't see to find how this is set. I guess as a final question, can I just get rid of SCIM? Or is that tied into the window manager somehow? I do appreciate any clarifications that I can get. Thanks.

  • How to add security zone information to files?

    - by user33938
    I recently enabled "Do not preserve zone information in file attachments", to get rid that annoying "Do you want to run this program" security warning. Now, how can I add this information to a file that doesn't have it? I would like to get that warning back on certain files.

  • How to show window contents while dragging in Windows Server 2008 R2?

    - by Andrew Arnott
    I just installed Windows Server 2008 R2, including the Desktop Experience feature, and activated the Themes service. I've activated Aero. I have everything there, except that when I drag windows, I only see the border of the window as I'm dragging. In other/older SKUs of Windows, there was a checkbox that I think said "Show Window Contents While Dragging", but I can't find such a checkbox on this OS.

  • Pre-crash iphone symptoms - odd user position, volume change

    - by BankStrong
    I'm seeing intermittent strange symtoms in my app: Blue blob (user position in MKMapView) starts "exploding" (odd, jerky animation). Can begin at startup and seems to indicate eventual problems. Speaker volume suddenly increases (back to level before I invoked kAudioSessionSetProperty_OtherMixableAudioShouldDuck). The app keeps running, but this change tells me to expect no more sounds from AVAudioPlayer. Also a reliable indicator of a future crash (on save, etc). I'm having trouble provoking this in the debugger (seems to only happen with movement in GPS). Any ideas to track it down?

  • Question about function returning array data

    - by Doug
    var grossBrackets = new Array( '300', '400', '500', '600', '700', '800', '900', '1000' ); function bracketSort( itemToSort ) { for( index = 0 ; index < grossBrackets.length ; index++ ) { if ( itemToSort < grossBrackets[index] ) { bracketData[index]++; } else if ( itemToSort > grossBrackets[7] ) { grossBrackets[7]++; } } return bracketData; } This is my current code, and I basically want to sort the data into their proper brackets. My source code is really long, but when I input these numbers into the function: 200.18 200.27 200.36 200.45 200.54 bracketData prints 5,5,5,5,5,5,5,5 or is there a better way to do this? Brackets: <300, <400, <500, <600, <700, <800, <900, <1000, greater than 1000

  • installing ruby/gnome2 on ruby1.9

    - by sawa
    My purpose is to install ruby/gnome2 and make it work with ruby1.9 on Ubuntu9.10. I already have ruby/gnome2 working with ruby1.8, but I need to make it work with ruby1.9. I also have ruby1.9 working. When I run within ruby-gnome2-all-0.19.3: ruby1.9 extconf.rb it eventually gives me: Target libraries: glib, gdkpixbuf, pango, atk, gtk, gconf, libglade Ignored libraries: gnomeprintui, panel-applet, gtksourceview, gtksourceview2, bonoboui, bonobo, libart, goocanvas, rsvg, gnomeprint, gstreamer, vte, gnomevfs, poppler, gnomecanvas, gtkglext, gnome, gtkmozembed, gtkhtml2 so it seems some packages failed to be installed. When I look for the log for example for the gnomeprintui part, it exits after returning: cheking for libgnomeprinrui-2.2... no but apt-get says I have the newest version of it. Can anyone tell me how to resolve this problem?

  • Problem with Rotating a UIScrollview

    - by leachianus.gecko
    Hey guys, I am having issues trying to get the pageControl sample code to work with rotation. I managed to get it to rotate but it does not visually loads correctly until I start to scroll (then it works fine). Any Idea on how I can fix this problem? Here is a link to the project if you want to see it in action. This code is based off the PageControl example apple has provided. here is the code: #import "ScrollingViewController.h" #import "MyViewController.h" @interface ScrollingViewController (PrivateMethods) - (void)loadScrollViewWithPage:(int)page; @end @implementation ScrollingViewController @synthesize scrollView; @synthesize viewControllers; - (void)viewDidLoad { amount = 5; [super viewDidLoad]; [self setupPage]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } - (void)viewDidUnload { [scrollView release]; } - (void)dealloc { [super dealloc]; } - (void)setupPage { NSMutableArray *controllers = [[NSMutableArray alloc] init]; for (unsigned i = 0; i < amount; i++) { [controllers addObject:[NSNull null]]; } self.viewControllers = controllers; [controllers release]; // a page is the width of the scroll view scrollView.pagingEnabled = YES; scrollView.contentSize = CGSizeMake(scrollView.frame.size.width * amount, 200); scrollView.showsHorizontalScrollIndicator = NO; scrollView.showsVerticalScrollIndicator = NO; scrollView.scrollsToTop = NO; scrollView.delegate = self; [self loadScrollViewWithPage:0]; [self loadScrollViewWithPage:1]; } #pragma mark - #pragma mark UIScrollViewDelegate stuff - (void)scrollViewDidScroll:(UIScrollView *)_scrollView { if (pageControlIsChangingPage) { return; } /* * We switch page at 50% across */ CGFloat pageWidth = _scrollView.frame.size.width; int dog = floor((_scrollView.contentOffset.x - pageWidth / 2) / pageWidth) + 1; // pageControl.currentPage = page; [self loadScrollViewWithPage:dog - 1]; [self loadScrollViewWithPage:dog]; [self loadScrollViewWithPage:dog + 1]; } - (void)loadScrollViewWithPage:(int)page { if (page < 0) return; if (page >= amount) return; MyViewController *controller = [viewControllers objectAtIndex:page]; if ((NSNull *)controller == [NSNull null]) { controller = [[MyViewController alloc] initWithPageNumber:page]; [viewControllers replaceObjectAtIndex:page withObject:controller]; [controller release]; } if (nil == controller.view.superview) { CGRect frame = scrollView.frame; frame.origin.x = frame.size.width * page; frame.origin.y = 0; controller.view.frame = frame; [scrollView addSubview:controller.view]; } } - (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation { [self setupPage]; } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations return YES; } #pragma mark - #pragma mark PageControl stuff @end

  • Activate COM object using website doesn't work in Windows 2003 server

    - by Tarun
    I have been trying really hard to activate and launch a COM object using an ASP.NET web application. The aspx website has a code-behind file that has a reference to this COM object (which is an actual application - a CAD software). When required, the VB code creates (or launches) the application. The complete set-up works in a Win-XP (32-bit) environment both under debugging using visual studio and when the website is accessed by an outside user (through IIS server in XP). But the same application doesn't get activated when it is hosted onto the Win-2003 (32-bit) IIS server. I get "Object reference not set to an instance of an object" error. The way I have setup in Win-XP was to grant ASP user and Internet guest user permissions to the COM object in the DCOM Config and since the windows firewall is enabled, I add the exe file (associated with the COM object) to the exception list. For the case of Win-2003 server, I add the Network Service permission to the COM object. But the setup doesn't seem to work at all. I am not sure what I am missing and how to get the application to launch. Any help will be greatly appreciated.

  • Count number of arguments to Excel formula in VBA

    - by Abiel
    I need to use VBA to determine the number of arguments passed to an Excel formula. For instance, suppose a cell contains the formula =MyFunc($A$1, "xyz", SUM(1,2,COUNT(C1:C12)), IF(B12,1,0)). Then the counter function should return 4. Does VBA contain any built-in functions for this, or does someone have an example of a regular expression that could calculate this?

    Hi guys, I'd like to build an application that, on interval, it checks for tweets containing a particular hashtag, and creates an individual Wordpress post for each tweet that it finds. What is the best way to do this? Are there existing plugins/tools available, or should I write my own custom plugin?

  • File open fails initially when trying to open a file located on a win2k8 share but eventually can su

    - by Ruddy Douglass
    Core of the problem: I receive "(0x80070002) The system cannot find the file specified" for roughly 8 to 9 seconds before it can open it successfully. In a nutshell, we have two COM components. Component A calls into Component B and asks for a UNC filename to write to - the filename returned doesn't exist yet, but the path does - it then does its work, creates and populates the file, and tells Component B its done by making another com call. At that point Component B will call MoveFile to rename the file to its "official" name. This code has worked for (literally) years. Its works fine on win2k3. Its works fine when its running on win2k8 and points to a share on a win2k3 server. It also runs fine, if the share is actually located on the same win2k8 machine that the code is running on. But if you run it on win2k8 and point it to a share on a different win2k8 server, it fails. Both Component A & component B exist in their own Windows Service running with as a domain admin account. The shares are configured for "Everyone/Full control" in all test environments, similarly so are the underlying folders that the share points to. All machines are in the same domain. During debugging I realized the file actually does exist by the time I get to checking manually for it - after several iterations it occurred to me that the file doesn't "show up" until some delay passes by - so I put in the loop below in component B as shown below: int nCounter = 0; while (true) { CFileStatus fs; if (CFile::GetStatus(tempname, fs)) break; SleepEx(100, FALSE); nCounter++; } This code does, in fact, exit and nCounter is generally between 80 & 90 iterations when it does -- indicating the file "appears" approx 8 to 9 seconds later. Once that loop exits the code can successfully rename the file and all further processing appears to work. I put a CFile::GetStatus in component A immediately before it calls into Component B and that indicates success - it can see the file and get its true size yet the call into component b made immediately after can not see the file until the above indicated delay passes. I have verified the pathnames are precisely the same, even though it would clearly have to be for the calls to eventually succeed after a pause of 8 to 9 seconds... When something like this occurs I always assume there is a bug in my code until proven otherwise, but given (a) this code has executed properly for a very long time and (other than my diagnostic loop added) has not changed, and (b) it works in all environments except the win2k8 - win2k8 share, I'm guessing there is some OS issue in here that i do not understand. Any insight would be helpful. Thanks!

  • Tablet as Car Computer

    - by luxurychair
    Okay, so forward this off to the right place if this isn't the right place to ask this question. I want to use a tablet computer as a car-computer. Minimum features would be to run my music (through iPod, Pandora, whatever I want) and GPS Navigation, watch TV or movies while I'm parked waiting for people, and the hard one: it needs to answer my phone calls with a pleasant interface much like in-dash systems do. It needs to detect that my phone is ringing in my pocket and provide an on-screen answer/ignore and then route the audio through the cars speakers. It would be nice to dial out and have address book access, but that is somewhat secondary. I have an iPhone myself and I figured that an iPad with 3G might make a good system for this - but I'm open to other options if an iPad can't do everything I need. I'm willing to write code, and I'm willing to jailbreak one or both devices. I haven't done much work in Obj-C, but I'm not opposed to learning a new language for this project. It's self enrichment for the most part, as I'm sure I can buy an indash entertainment system for less. Does anyone have experience with the iPhone/iPad SDK that can tell me whether or not it would be possible to get it an iPad to answer my calls in the car? What about an Android tablet? (that Adam looks promising, too).
