  • How to set an array to a list of values in VB.NET?

    - by IPX Ares
    I cannot figure out how to set an array to one of two sets of numbers (there will be more later), every way that I have tried throws some kind of error. I have tried to Dim the array inside the case statements, but then I cannot use the array in the For Each, which makes this worthless.... any ideas would be appreciated. Code: Dim HourArray() As Integer Select Case CurrentShapeRow(ROW_PERIOD) Case "ON", "2X16" HourArray = {6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21} Case "2X8", "5X8" HourArray = {0, 1, 2, 3, 4, 5, 22, 23} Case Else Throw New Exception(String.Format("Unhandled Period: {0}", CurrentShapeRow(ROW_PERIOD))) End Select For Each HourCount As Integer In HourArray() 'DO SOME STUFF HERE Next

  • ImageMagick vs. Cairo on Vector Graphics rasterization

    - by Sherwood Hu
    I am working on a project that needs rasterizing of drawings into image files. I have already got it work using GDI+. Wanting to create a portable solution, I am also looking into other solutions and found two - cairo and imagemagick. I am new to both, but it seems that ImageMagick can do almost all the stuff - drawing lines, arcs, circles, text etc.. plus many bitmap manipulation. However, Cairo is mentioned as competitor to GDI+ in web sites. ImageMagick is never mentioned for this purpose. I do not have time to invest on both libraries. I need to decide which one is worthy. I prefer to ImageMagick, as it seems much more powerful. What's your opinion on the two graphic libs?

  • Using TortoiseHg’s Repository explorer

    - by krebstar
    I posted this question on superuser.com but I wasn't sure if it was appropriate there.. Anyway: Hi, I'm coming from a TortoiseSVN background and decided to give TortoiseHg a try.. One thing I got really used to with TortoiseSVN was the SVN Repo-Explorer, which worked quite similarly to Windows Explorer.. However, when I tried to use TortoiseHg's Repository Explorer, what I got was something else, it was more like TortoiseSVN's Show Log. It showed me what the recent commits were and what files were changed and even had nifty graphs.. However, I'm still left wanting for TortoiseSVN's Repo-Explorer.. Does TortoiseHg have anything like this? How am I supposed to poke around the Repository if I can only view changed stuff? Thanks, kreb

  • Strong name validation failed on VB.NET Assembly

    - by Matt Baker
    I have a VB.Net 1.1 application works just fine after compiling in Visual Studio. However, I want to use ILMerge to combine all the referenced assemblies into a single executable just to make it easier to move around. After I send it through ILMerge and try to run it I get the error "Strong name validation failed for .exe" ..... But none of my stuff is strong named! I saw this post here: http://stackoverflow.com/questions/403731/strong-name-validation-failed and tried running it through 'sn.exe -Vr .exe' but that gives me this error: ".exe does not represent a strongly named assembly" Has anyone else had this problem before? How do I fix it?

  • Asp.Net 3.5 Routing to Webservice?

    - by Maushu
    I was looking for a way to route http://www.example.com/WebService.asmx to http://www.example.com/service/ using only the ASP.NET 3.5 Routing framework without needing to configure the IIS server. Until now I have done what most tutorials told me, added a reference to the routing assembly, configured stuff in the web.config, added this to the Global.asax: protected void Application_Start(object sender, EventArgs e) { RouteCollection routes = RouteTable.Routes; routes.Add( "WebService", new Route("service/{*Action}", new WebServiceRouteHandler()) ); } ...created this class: public class WebServiceRouteHandler : IRouteHandler { public IHttpHandler GetHttpHandler(RequestContext requestContext) { // What now? } } ...and the problem is right there, I don't know what to do. The tutorials and guides I've read use routing for pages, not webservices. Is this even possible? Ps: The route handler is working, I can visit /service/ and it throws the NotImplementedException I left in the GetHttpHandler method.

  • Microsoft T-SQL to Oracle PL/SQL translation

    - by Michael Prewecki
    I've worked with T-SQL for years but i've just moved to an organisation that is going to require writing some Oracle stuff, probably just simple CRUD operations at least until I find my feet. I'm not going to be migrating databases from one to the other simply interacting with existing Oracle databases from an Application Development perspective. Is there are tool or utility available to easily translate T-SQL into PL/SQL, a keyword mapper is the sort of thing I'm looking for. P.S. I'm too lazy to RTFM, besides it's not going to be a big part of my role so I just want something to get me up to speed a little faster.

  • How to stop NpgsqlDataReader from blocking?

    - by Swingline Rage
    Running the following code against a large PostgreSQL table, the NpgsqlDataReader object blocks until all data is fetched. NpgsqlCommand cmd = new NpgsqlCommand(strQuery, _conn); NpgsqlDataReader reader = cmd.ExecuteReader(); // <-- takes 30 seconds How can I get it to behave such that it doesn't prefetch all the data? I want to step through the resultset row by row without having it fetch all 15 GB into memory at once. I know there were issues with this sort of thing in Npgsql 1.x but I'm on 2.0. This is against a PostgreSQL 8.3 database on XP/Vista/7. I also don't have any funky "force Npgsql to prefetch" stuff in my connection string. I'm at a complete loss for why this is happening.

  • ruby 1.9: invalid byte sequence in UTF-8

    - by Marc Seeger
    I'm writing a crawler in ruby (1.9) that consumes lots of HTML from a lot of random sites. When trying to extract links, I decided to just use .scan(/href="(.*?)"/i) instead of nokogiri/hpricot (major speedup). The problem is that I now receive a lot of "invalid byte sequence in UTF-8" errors. From what I understood, the net/http library doesn't have any encoding specific options and the stuff that comes in is basically not properly tagged. What would be the best way to actually work with that incoming data? I tried .encode with the replace and invalid options set, but no success so far...

  • Best practices for TDD BDD with code that uses external services / api

    - by adam
    I'm using a twitter gem which basically accesses twitter and lets me grab tweets, timeline etc. Its really good but I have a lot of my code that uses the stuff it returns and I need to test it. The things the gem returns aren't exactly simple strings, there pretty complex objects (scary as well) so im left scratching my head. So basically I'm looking for an answer, book, blog, open-source project that can show me the rights and wrongs of testing around external services. answers that are either not language centric or ruby/rails centric would most greatly be appreciated.

  • Java Meta Search Engine API

    - by Loki
    I'm currently researching Java libraries to help in building a meta type search engine in the sense of being able to replace any given search engine in the back-end of the application or to simultaneously search using multiple search engines. I'm not interested in the GUI part here, just the generalization of search engine APIs and usage. I'd like to know about the common libraries used to achieve this task and if there are any common patterns used in this case. I imagined that this problem is common enough to be able to find plenty of stuff on Google, but it seems like search is a very proprietary domain and not much information is fed back to the community.

  • Is it naughty to have a large utility file?

    - by banister
    In my C project I have quite a large utils.c file. It is really full of many utilities of different sorts. I feel a bit naughty just stuffing different miscellaneous functions in there. For example it has some utilities related to low level stuff such as a lowercase() function, and it also has some quite sophisticated utilities such as converting to/from different colour formats. My question is, is it very naughty to have such a large utils.c with many different types of utilities in it? Should I break it up into many different kinds of utility files? Such as graphics_utils.c and so on What do you think?

  • A JTAG emulator for use with a Hawkboard and OpenOCD?

    - by David Brown
    I'd like to try bare metal ARM programming with the Hawkboard, but the deployment process looks awful. I'm totally new to this, so I could be misunderstanding the instructions, but it appears that I have to use a program called AISgen to convert the binary file, then boot with u-Boot over UART and copy the AIS binary into memory. Not only is that a lot of stuff to do every time I make a change, it also doesn't give me the ability to debug with GDB. The best solution for this that I can find is JTAG. But the prices for these JTAG emulators look ridiculous. I'm not even sure which ones will work with the Hawkboard and which ones won't. So far, my best bet appears to be the Flyswatter, but the pin layout is different. Basically, I need something that's relatively cheap and works with the Hawkboard and OpenOCD. Any suggestions? Or is there another way I could do this, perhaps?

  • Hosting WCF services

    - by Jayesh
    Hi, I have been working on a Silverlight app that consumes a WCF service. [on Visual Studio] as a matter of simplicity I created a WCF service in the project itself [as-in I didnt host it in IIS, but let the build-in webdev server in VS do it for me] It works well, now I want to deploy it on IIS 7.0, can you tell me If i would need to host the service independently and then the remaining stuff or if I just publish the website, the service would be hosted too and the Silverlight client would be able to communicate with the service. Please help! Thanks

  • Global Ignores for SVN?

    - by Michael Stum
    Is there a way to setup a global list of Ignores for a SVN Repository or for the SVN Client on the PC? The only reason I'm using tools like Tortoise/Ankh/VisualSVN is because I want to only check in the files I need without all the bin/obj/Resharper stuff. I'm spoiled by .gitignore and .hgignore which I just copy to a repository and then use "git commit -a" without having to care about checking in junk. I know I can manually set it, but that's tedious to do and I think it had to be applied to every new folder that gets created as well. Using SVN under Windows if that matters

  • Editing a 9gb .sql file

    - by CERIQ
    Hi. I've got a "slightly" large sql script saved as a textfile. It totals in at 8.92gb, so it's a bit of a beast. I've got to do some search and replaces in this file(specifically, change all NOT NULL to NULL, so all fields are nullable) and then execute the darned thing. Does anyone have any suggestions for a text editor that would be capable of this? The other way that I can see to solve the problem is to write a program that reads a chunk, does a replace on the stuff I need, and then save it to a new file, but I'd rather use some standard way of doing this. It also does not solve the problem of opening the beast up in sql server management studio to execute the darned thing... Any ideas? Thanks, Eric

  • Migrating VseWss project to WspBuilder

    - by Khurram Aziz
    I have a VseWss project that I want to migrate to WspBuilder. The project has many features (Content Types, Fields, Lists, Event Listeners, Workflows, ASPX files, their code behind etc) and the project references couple of other assemblies as well. And it does the SafeControls entries and deploys the assemblies into GAC etc Important aspect is; the WSP that gets created from the VseWss is deployed to the production server and while migrating I want to preserve all of these things so that when I create the WSP from WspBuilder things are transparent for the Sharepoint Administrators. Please guide me how to proceed...any online tutorial or related stuff that talks about migrating a real world VseWss project (with 10-20 different types of features)

  • Win XP error 0x80041003 using GetObject/winmgmts

    My computer is called "neil" and I want to set some values using WMI in vbScript. I adapetd the script below from one supplied by Microsoft. When I run it in my browser I get Error Type: (0x80041003) /dressage/30/pdf2.asp, line 8 I suspect it is some registry/security setting. Any advice?

The line breaks seem to have been introduced in the process of paasting into this form. Well spotted - I was using a PDF file name "ascii". I added a .pdf extension but still get the error. I suspect you're right that it's to do with admin rights. Here's more about the setup and what I'm trying to achieve. Win2pdf is a product for writing PDFs by works by simulating a Windows printer. You "print" the page, select win2pdf in the print dialog and it then asks for a file name. I have it installed on my pc (called Neil) and it works fine in this conventional way. My aim is to write an html page to a PDF file using win2pdf - but via ASP/vbscript/javascript rather than with manual intervention. The script for doing this was provided by win2PDF's tech support but when it did not work, that was the limit of their understanding. In the sample script the file ascii.asp just produces a table of ascii codes/characters. The URL given is on my own PC which has IIS set up to run scripts which it does fine. The error I get occurs on about the fourth line executed. I am logged in with full admin rights - I think! But I'm no expert. I hope this helps to give some more specific suggestions about how to check/fix the admin rights.

  • Could an ontology suitably replace an RDBMS for a web app?

    - by Thomas
    I'm considering storing the content of a web app in an RDF or OWL ontology instead of an RDBMS. However, when I research ontologies they seem to always exist in the context of publicly accessible data stores serving as the backbone of the semantic web. I've never heard of them being used as the content engine behind a web app. Is it reasonable to use an ontology instead of an RDBMS for such an application? (Again, this is just for content. User data, commerce and stuff like that will stay in a database as I see no need to reinvent the wheel there.)

  • Portable applications for phones?

    - by peoro
    What's the best way to write an application in order to get it working on the several phones out there (iPhone, symbian-based, xpPhone, and so on)? The idea I have in mind is that of writing a few interfaces to abstract from phone-dependent stuff (ie: some Input/Output interfaces), implementing such interfaces on the several phones and then writing an application that doesn't use any phone-dependent thing. But is this really possible? What would be the language I should choose for my interfaces and applications? (would love to use C++, hopefully even with GCC extensions) Is there any project that aims to offer what I need? (maybe something like SDL?)

  • Background problem of opengl 3d object over iphone camera view

    - by user292127
    Hi, I'm loading opengl 3d objects over the iphone camera view. When opengl view is loaded it's loading with a opengl 3d object with black background. The black background color will block the camera view.I just want to clear background color of opengl view so that I could load only the 3d object to the camera view. I had tried glclearcolor(1.0,1.0,1.0,0.0); but no change to background color. I had also tried to clear background color opengl view using [glview setbackgroundColor:[UIColor clearColor]];. No change in back ground color. Can any one help me with this stuff ? I'm new to opengl. Thanks in advance

  • Using CGContext to display a sprite sheet iPhone

    - by Mike
    Hello, So I have a spritesheet in png format, and have already worked out the coordinates for what I want to display. I'm trying to create a method that will return a UIImage when passed the location information on the spritesheet. I'm just not sure how to use the CGContext stuff along with the the coordinates to return an UIImage. I was looking to CGContextClipToRect because I think that is the way to do it, but I just can't seem to get it to work. Something like this CGSize size = CGSizeMake(xSize, ySize); UIGraphicsBeginImageContext(size); //CGContextClipToRect(spriteSheet.size, imageRect); [spriteSheet drawAtPoint:CGPointMake(xPos, yPos)]; UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); return scaledImage; returns only what is in the size Context. I need to be able to "move" this size window around the spritesheet if that makes sense. Any help would be appreciated. Thanks, Mike

  • What's the best way to check that environment variables are set in Unix shellscript

    - by AndrewR
    I've got a few Unix shell scripts where I need to check that certain environment variables are set before I start doing stuff, so I do this sort of thing: if [ -z "$STATE" ]; then echo "Need to set STATE" exit 1 fi if [ -z "$DEST" ]; then echo "Need to set DEST" exit 1 fi which is a lot of typing. Is there a more elegant idiom for checking that a set of environment variables is set? EDIT: I should mention that these variables have no meaningful default value - the script should error out if any are unset.

  • Word mergefield wildcard not correctly matching

    - by aZn137
    Hello, Below is my mergefield code: { IF { MERGEFIELD Subs_State } = "GA" "blah blah" "{ IF { MERGEFIELD CEOrgStates } = "GA" "blah blah" ""} "} I'm pulling records from a MS Access db. My goal is to check whether a record has Subs_State field matching "GA", or the CEOrgStates has the word "GA" (some records have stuff like "|FL|CA|GA|CT|KY|" (no quotes)). When I merged the docs, Word doesnt seem to be able to match with the wildcards: If I use and compare "*GA" (fields ending with GA), it works; however, the double wildcards "*GA*" dont seem to work at all. Here are the things I’ve tried: Have data in lowercase, then compare with lowercase Have data in lowercase, convert to and then compare with uppercase Do the opposite of the above 2 with uppercase data Use “*GA*” and “*ga*” (no pipe) Use different delimiters Nothing seems to work with the double wildcard matching. What am I doing wrong? Thanks!
