  • How to replace a multipart message schema in a map without replacing the map

    - by BizTalkMama
    I have an orchestration map that maps two source messages into one destination message. When the schema for one of the source messages changes, I was hoping to be able to click on the input message part and select "Replace Schema" to refresh the schema for just the message part affected. Instead I can only replace the entire multipart message schema with the single message part schema. My only other option seems to be to generate a new map from the orchestration transform shape, but this means I have to recreate all the links in my map... Does anyone know of a more efficient way to update this type of schema?

  • How to make columns as wide as the widest entry?

    - by Helper Method
    For a gcc cheatsheet I'm writing, I want to create a table which should describe how gcc interprets different file endings. The table I created so far is defined as follows: |====================================================================== |.c |C source code which must be preprocessed. |.i |C source code which should not be preprocessed. |.h |C header file to be turned into a precompiled header. |.s |Assembler code. |other | An object file to be fed straight into linking. Any file name with no recognized suffix is treated this way. |====================================================================== The problem I have is that the table spans the total page width, but what I want is that each column only is as wide as it's widest entry, and that the table will span only as much witdh as it needs.

  • Disadvantages of hard coding credentials? What's the resolution?

    - by SeeBees
    I am building a Sharepoint web part that will be used by all users. The web part connects to a web service which needs credentials with higher privileges than common users. I hard coded credentials in the web part's code. query.Credentials = new System.Net.NetworkCredential("username", "password", "domain"); query is an instance of the web service class This may not be a good approach. In regard with security, source code of the web apart is available to people who are not allowed to see the credential. This is bad enough, But is there any other drawback of this approach? How to prevent hard coding credentials into the source code? Thanks

  • How to update SQL Server database from multiple data sources for ASP.Net MVC 4 application

    - by shaz
    I have 10+ SQL Server databases, from where I would use one table from each database to display information using the application that I am creating. For instance, DB1, DB2....DB10. NewDB (Account, Country, Costcenter....etc.). I have started with creating a new database which would contain all the information from all those 10+ databases. However, I am confused in many cases. First of all what process should I follow? Shall I create a table (in new database) with the same structure as the actual data source and insert data from actual data source to new database? Should I be doing this on the DBMS? If so, is it some scripting? (hint expected since very new to this) I am creating a report generation application which has 10+ data sources. I need some hint which way should I proceed? Thanks for advice/help in advance.

  • Can I write a test that succeeds if and only if a statement does not compile?

    - by Billy ONeal
    I'd like to prevent clients of my class from doing something stupid. To that end, I have used the type system, and made my class only accept specific types as input. Consider the following example (Not real code, I've left off things like virtual destructors for the sake of example): class MyDataChunk { //Look Ma! Implementation! }; class Sink; class Source { virtual void Run() = 0; Sink *next_; void SetNext(Sink *next) { next_ = next; } }; class Sink { virtual void GiveMeAChunk(const MyDataChunk& data) { //Impl }; }; class In { virtual void Run { //Impl } }; class Out { }; //Note how filter and sorter have the same declaration. Concrete classes //will inherit from them. The seperate names are there to ensure only //that some idiot doesn't go in and put in a filter where someone expects //a sorter, etc. class Filter : public Source, public Sink { //Drop objects from the chain-of-command pattern that don't match a particular //criterion. }; class Sorter : public Source, public Sink { //Sorts inputs to outputs. There are different sorters because someone might //want to sort by filename, size, date, etc... }; class MyClass { In i; Out o; Filter f; Sorter s; public: //Functions to set i, o, f, and s void Execute() { i.SetNext(f); f.SetNext(s); s.SetNext(o); i.Run(); } }; What I don't want is for somebody to come back later and go, "Hey, look! Sorter and Filter have the same signature. I can make a common one that does both!", thus breaking the semantic difference MyClass requires. Is this a common kind of requirement, and if so, how might I implement a test for it?

  • Will the changes of a property in a "StaticResource instance" reflected in UI ?

    - by Anish
    I have used object data provider to create instance of my view-model as below: <ObjectDataProvider x:Key="Datas" ObjectType="{x:Type ViewModel:UserControlViewModel}"> </ObjectDataProvider> <DataTemplate x:Key="SourceGrid"> <WPFToolKit:DataGrid x:Name="SourceDataGrid" ItemsSource="{Binding Source={StaticResource Datas},Path=SourceGridData}" CanUserSortColumns="True" GridLinesVisibility="None" IsSynchronizedWithCurrentItem="True" SelectionUnit="FullRow"></WPFToolKit:DataGrid> </DataTemplate> My question is... as I am using the instance - "Datas" as staticResource, will the changes to the property "SourceGridData" get reflected in UI?

  • Maven and db4o dependency

    - by Jens Jansson
    I'm intrigued to test new frameworks in the Java world, and decided to create a new project that takes advantage of Maven and db4o. I'm starting to get a hang of Maven, but I have a hard time adding db4o as a dependency to the project. First problem is that db4o doesn't exist in the official Maven repositories. Next up comes the problem that db4o seem to have recently restructured their whole site's URI:s, so I'm getting 'site not found' messages all the time when I try to navigate their site. I found somewhere a potential Maven repository that should be at https://source.db4o.com/maven but I get all the time "Error reading archetype catalog https://source.db4o.com/maven Unable to locate resource in repository" when I try to access it. So, any suggestions on how I'll get db4o up through Maven? I've managing Maven through Eclipse with the M2Eclipse plugin.

  • Xcode + Perforce: it frequently shows me the spinning wheel for no reason! What can i do?

    - by GamingHorror
    While working on an Xcode project i keep getting the spinning wheel while switching files, scrolling, searching, typing, debugging, removing breakpoints, switching back from another app or saving. It also happens before compiling but usually it just happens from time to time for no apparent reason. This is the second time this started happening in a Xcode project and it's driving me nuts. It completely breaks my flow of work to have to wait for the spinning wheel to go away (2-5 seconds). What on earth could i possibly do to ... figure out what's causing the problem? resolve the problem? More details: When any project is small, everything is super-smooth with Xcode and Perforce. Two of my projects eventually had this spinning wheel problem after about 4 weeks of work. It only happened with those two projects so far. They consist of around 1000-1200 files in source control, most of them assets. The problem occurs even if i manually check out the whole project in Perforce. The problem is gone when i copy the project directory and work in the copy which is no longer under source control, or if i create a branch in Perforce and work in the branch (under source control). One of these projects i shared with a colleague, and he had exactly the same issues on his Mac. We eventually switched to Subversion and the spinning-wheel issue immediately went away. Now that i've received an updated copy of the project and simply put it under Perforce as a new project, the problem also went away (so far it did not resurface). It leads me to think that it may be caused by a larger number of file revisions. The server itself (version 2009.1) is on a different (Windows) machine on my LAN, so there's definetely no Internet lag involved. The complete repository is just 1 GB in size spread over a dozen projects or so. I'm sorry if the question seems more like a support inquiry for Perforce. However i'm using the free version of Perforce so i'm not entitled to get support from them. I hope no one minds me asking here. I'm really bummed out by this. I don't want to have to create a new branch for the project each time the spinning wheel problem surfaces.

  • Using same Debug settings for Start External Program across 32 bit and 64 bit debug environments

    - by Michael Prewecki
    We use a mixture of 32-bit and 64-bit development environments. Some of our class libraries are debugged using a 32-bit application so we have debug settings for "Start External Program" and "Working Directory". The problem is that the settings need to be different since the 32-bit application is installed to C:\Program Files\xxx (on the 32-bit dev enviroment) or C:\Program Files (x86)\xxx (on the 64-bit dev environment) Is there a way to use some sort of tag like %PROGRAMFILES% or $(ProgramFiles) so that Visual Studio 2008 will know where to look for the external program? This wouldn't be a major issue except the solution file (where the debug information is saved) is checked into source control...so getting the latest version of the solution from our source repository keeps yoyo'ing the debug settings between the two program files locations.

  • Displaying xaml resources dynamically?

    - by Robert
    I used Mike Swanson's illustrator to xaml converter to convert some of my images to xaml. The convert creates a viewbox that contains the image. These viewboxes I made resource files in my program. The code below shows what I'm trying to do: I have a viewmodel that has an enum variable called PrimaryWinding of type Windings. The values PrimD and PrimY of the enum select the respective PrimD and PrimY xaml files in the resources. <UserControl.Resources> <DataTemplate x:Key="PrimTrafo" DataType="{x:Type l:Windings}"> <Frame Source="{Binding}" x:Name="PART_Image" NavigationUIVisibility="Hidden"> <Frame.LayoutTransform> <ScaleTransform ScaleX="0.5" ScaleY="0.5"/> </Frame.LayoutTransform> </Frame> <DataTemplate.Triggers> <DataTrigger Binding="{Binding}" Value="PrimD"> <Setter TargetName="PART_Image" Property="Source" Value="Resources\PrimD.xaml" /> </DataTrigger> <DataTrigger Binding="{Binding}" Value="PrimY"> <Setter TargetName="PART_Image" Property="Source" Value="Resources\PrimY.xaml" /> </DataTrigger> </DataTemplate.Triggers> </DataTemplate> </UserControl.Resources> <!--The contentcontrol that holds the datatemplate defined above--> <Grid > <Grid.ColumnDefinitions> <ColumnDefinition Width="2*"></ColumnDefinition> <ColumnDefinition Width="2*"></ColumnDefinition> <ColumnDefinition Width="1*"></ColumnDefinition> </Grid.ColumnDefinitions> <ContentControl Grid.Column="0" Content="{Binding PrimaryWinding}" ContentTemplate="{StaticResource PrimTrafo}"/> </Grid> This code works. Only I can't resize the drawings to the size of the grid cell. I added the ScaleTransform class to resize the image. Is a Frame the wrong class to hold the drawings? Should I use the ScaleTransform class to resize the drawing to the size of the cell? And how can I do that dynamically?

  • Socket left in TIME_WAIT after file transfer via netcat

    - by com
    Using Copying by NetCat I am trying to copy files throught network by NetCat. From console it work pretty well. First I run listening netcat on the destination machine and after I run sending on source machine. The problem is it's doen't work from script from the source machine: ssh -f user@$desthost 'nc -l 1234 | tar xvf - /dev/null &' #listening on destination host tar cv /tmp/file | nc $desthost 1234 #sending to destination host I saw that after running port 1234 is still was open and status of the socket was TIME_WAIT. If you know what's the problem, please, help me out. And by the way, after copying how can I validate that the content is identical? Thanks! Addendum: I found one very strange thing, the same implementation with screen on destination work works, but not stable, sometimes it doesn't copy a file. ssh user@$desthost screen -dm -S test 'nc -l 1234 | tar xvf - ' #listening on destination host Maybe there is an issue with timeout?

  • Are there Adaptive Replacement Cache patent-free alternatives?

    - by aleccolocco
    An open source high-performance project I'm working on needs to keep a cache of parsed/compiled files. A plain LRU or a plain LFU wouldn't fit. Plain LRU wouldn't work as there will be remote batch/spider processes hitting the service regularly. Plain LFU wouldn't work because content will age. ARC seems like the perfect solution but since IBM holds patents to it at least one open source project dropped it. Are there any (good enough) alternatives? EDIT: I'm not looking for exactly the same thing, just something that could handle those two situations. Perhaps some simple strategy with timestamps and sources. There have to be many programmers who faced this situation before. That's why the "good enough" bit.

  • Scala : cleanest way to recursively parse files checking for multiple strings

    - by fred basset
    Hi All, I want to write a Scala script to recursively process all files in a directory. For each file I'd like to see if there are any cases where a string occurs at line X and line X - 2. If a case like that occurs I'd like to stop processing that file, and add that filename to a map of filenames to occurrence counts. I just started learning Scala today, I've got the file recurse code working, and need some help with the string searching, here's what I have so far: import java.io.File import scala.io.Source val s1= "CmdNum = 506" val s2 = "Data = [0000,]" def processFile(f: File) { val lines = scala.io.Source.fromFile(f).getLines.toArray for (i = 0 to lines.length - 1) { // want to do string searches here, see if line contains s1 and line two lines above also contains s1 //println(lines(i)) } } def recursiveListFiles(f: File): Array[File] = { val these = f.listFiles if (these != null) { for (i = 0 to these.length - 1) { if (these(i).isFile) { processFile(these(i)) } } these ++ these.filter(_.isDirectory).flatMap(recursiveListFiles) } else { Array[File]() } } println(recursiveListFiles(new File(args(0))))

  • Is there a reasonable way to attach new path to PATH in bashrc?

    - by Ripley
    Guys I constantly need to attach new paths to the PATH environment variable in .bashrc, like below: export PATH=/usr/local/bin:$PATH Then to make it take effect, I always do 'source ~/.bashrc' or '. ~/.bashrc', while I found one shortcoming of doing so which make me uncomfortable. If I keep doing so, the PATH will getting longer and longer with many duplicated entries, for example in the previous command, if I source it twice, the value of PATH will be PATH=/usr/local/bin:/usr/local/bin:/usr/local/bin:$PATH(<-the original path). Is there a more decent way to attach new path to PATH in bashrc without making it ugly?

  • phpunit - generate tests for all the classes from a directory

    - by joe
    Hi! I have a directoy structure, and all the classes of the business logic are placed in the app_dir/lib/ directory. I would like to generate unit tests for all the classes from this lib/ folder. The problem is, that I haven't found any option to specify the source directory, only the source file: from app_dir: phpunit --skeleton-class lib/ Error: "lib/.php" could not be opened. Is it the only solution to write my own php script, which iterates through the /lib folder and calls the skeleton generator for every file found? And how can I specify the output folder, where all the generated test files are placed? Thanx, Joe

  • Adding Street View controls (the two icons just above the +) to a Google Map (v3)

    - by AlexV
    It's probably something really simple, but I can't find it in the docs and I can't find a map with it to check it's source... I use version 3 of the API. I guess it's an something to add in myOptions? var latlng = new google.maps.LatLng(-34.397, 150.644); var myOptions = { zoom: 8, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP } map = new google.maps.Map(document.getElementById('map_canvas'), myOptions); Currently I only have dragging controls and the zoom pane controls. I would like to have the two Street View controls icons too. If you want full source, I'm using this example as a base (how would you add Street View controls to this example?).

  • Resizing an image with alpha channel

    - by Hafthor
    I am writing some code to generate images - essentially I have a source image that is large and includes transparent regions. I use GDI+ to open that image and add additional objects. What I want to do next is to save this new image much smaller, so I used the Bitmap constructor that takes a source Image object and a height and width, then saved that. I was expecting the alpha channel to be smoothed like the color channels, but this did not happen -- it did result in a couple of semitransparent pixels, but overall it is very blocky. What gives? Using img As New Bitmap("source100x100.png") ''// Drawing stuff Using simg As New Bitmap(img, 20, 20) simg.Save("target20x20.png") End Using End Using Edit: I think what I want is SuperSampling, like what Paint.NET does when set to "Best Quality"

  • Problem with absolute positioning div over SWF and IE 8.

    - by Michael S. Kelly
    I'm attempting to use the old IFrame-over-SWF trick to get HTML to display "inside" a SWF. I'm following the example provided by Brian Deitte at: http://www.deitte.com/IFrameDemo3/IFrameDemo.html. (The source code can be viewed and downloaded by right-clicking on the SWF and selecting "View Source".) In the latest versions of Firefox, Google, Opera, and Safari on the Mac, it all looks good. But in IE 8 the absolutely positioned div containing the IFrame is positioned too far up and left, and the height and width are considerably smaller. Thoughts?

  • How do you use Exslt.dyn (especially the 'evaluate' method) in Umbraco?

    - by jeffreypriebe
    I am trying to execute the string contained in an XSL variable. Umbraco has hooks for several Exslt pieces, but it seems the Exslt.dyn (Exslt.dynamic) is not one of them. How do you add it in? Acceptable methods (in order of preference: Writing your own XSLT extension (possibly using existing Umbraco code for Exslt Dynamic). Uploading the XSL from http://www.exslt.org/dyn/functions/evaluate/index.html into Umbraco. Modifying the Umbraco source to add it (possibly using existing Umbraco code for Exslt Dynamic). The reason I mention Exslt Dyanmic is because some Umbraco XSLT sources show a reference that I am assuming existing in some versions of Umbraco. I cannot find it in the source code, however. (Example: the XSL sources pasted in here: http://our.umbraco.org/projects/starter-kits/business-website-starter-pack/general-%28bugs,-feedback,-feature-requests%29/8085-Changing-the-first-day-to-fx-monday)

  • CRC32 calculations for png chunk doesn't match the real one

    - by user2507197
    I'm attempting to mimic the function used for creating CRC's in PNG files, I'm using the autodin II polynomial and the source code from: http://www.opensource.apple.com/source/xnu/xnu-1456.1.26/bsd/libkern/crc32.c My tests have all been for the IHDR chunk, so my parameters have been: crc - 0xffffffff and 0 (both have been suggested) buff - the address of the IHDR Chunk's type. length - the IHDR Chunk's length + 4 (the length of the chunk's data + the length of the type) I printed the calculated CRC in binary, which I compared to the actual CRC of the chunk. I can see no similarities (little-big endian, reversed bits, XOR'd, etc). This is the data for the IHDR chunk (hexadecimal format): length(big endian): d0 00 00 00 (13) type: 49 48 44 52 data: 00 00 01 77 00 00 01 68 08 06 00 00 00 existing CRC: b0 bb 40 ac If anyone can tell me why my calculations are off, or give me a CRC32 function that will work I would greatly appreciate it. Thank-you!

  • ns-2 c++ file changes

    I have just installed a network simulator program called ns-2 and I am trying to familiarize myself with it by going through the tutorial by Marc Greis. When I get to the stage where I'm messing around with C++ source files and related program C++ source files as stated in http://www.isi.edu/nsnam/ns/tutorial/index.html, I don't know what to do as there are enough inconsistencies between the version of ns-2 that I downloaded (which is the latest stable build) and the guide. What would your recommendations in this case, as I don't know what to do with it as a newbie? Thanks in advance for your help!

  • Does JSLint parse DOM functions?

    - by Paul
    I tried to use the parse() function of JSLint to parse three pieces of JavaScript code: function(b, c){var a = b + c; return a; } window.addEventListener('click', click_hanlder, true); document.documentElement.innerHTML; Here's the code, which is copied and pasted from the JSLint self-parse example: ` try { parse = make_parse(); var source = "something to parse";//replaced by the code above tree = parse(source); if (tree) { document.write(JSON.stringify(tree, ['key', 'name', 'message', 'value', 'arity', 'first', 'second', 'third', 'fourth'], 4)); } } catch (e) { document.write(JSON.stringify(e, ['name', 'message', 'from', 'to', 'key', 'value', 'arity', 'first', 'second', 'third', 'fourth'], 4)); } ` The output: returns a correct tree. returns a tree with only one node of "window". crashes the browser. I'm wondering whether JSLint doesn't support DOM function.
