  • How would I access the Windows Login (Authentication) API from a C++ Service Application?

    - by Gabriel
    Let us imagine for a moment that I have a piece of hardware that can act as an authentication for a user on a given system. I want to write an application in C++ to run as a service, look for this device and if found log the appropriate user in. I believe I have found the API's I would need to use to perform the hardware and service portions of the application but am having a hard time nailing down a way to create a "real" user login. Is this possible? If so where would I look to find resources on accomplishing this? I think of it as being an analog to fingerprint scanner login type devices.

  • Ignoring build number when referencing dll

    - by brickner
    I have one solution with a .NET 4.0 project (C#) that produces a delayed signed dll, that I dotfuscate and sign. EDIT: This is how I version the dll: [assembly: AssemblyVersion("0.7.0.*")] [assembly: AssemblyFileVersion("0.7.0.0")] I have another solution with a .NET 4.0 project (C++/CLI) that references the signed dll and produces a signed dll (actually, delayed signed and signed in a post build because of a flaw in the C++ build system). The problem is that the reference to the dll contains a specific version number, which includes even the build number (I want to have a build number). Every time I build the referenced dll, I have to change the project settings file (.vcxproj) so it reference the new version dll. Since I work with source control, this is very inconvenient (different computers might have different build numbers since each computer build its own referenced dll - the referenced dll is not in the source control). If I don't change the reference, I get a warning: warning MSB3245: Could not resolve this reference. Could not locate the assembly... And many errors like this: error C3083: 'Foo': the symbol to the left of a '::' must be a type These are resolved once I change the reference. How do I make the reference ignore the build number or even the entire version number?

  • SSIS - Multiple Configurations

    - by Mick Walker
    I have inherited a SSIS project. I have never worked with SSIS before, and the one thing that seems strange to me, is that there is no way to manage multiple configurations. For each SSIS package we have 3 delpoyment environments, DEV, UAT and PRODUCTION. At the moment I am having to edit the configuration for every package we deploy manually for each change (and there are a lot of packages). Does anyone know of a more graceful way to handle these configuration changes?

  • Limitation of Attachment size when using SMTP

    - by Gas Gemba
    Hi, I wrote a C++ program to send a mail using SMTP. But when I attach any files I notices that a single file's size always is limited to 808 bytes. As an example if I send a text file with 10 KBs, when I download the attachment it has only text worth 808 bytes. If the large file is a zip file, it gets corrupted in unzipping obviously due to CRC failure. I used a MAPI library to send larger files without a problem. Is this a network limitation of SMTP? Can someone please explain why this is happening?? Thank You!!!

  • Extraction Event

    - by Anicho
    So I have the following code: public override void Extract(object sender, ExtractionEventArgs e) { if (e.Response.HtmlDocument != null) { var myParam = e.Request.QueryStringParameters.Where(parameter => parameter.Name == QueryName).Select(parameter => parameter.Value).Distinct(); myParam. // add the extracted value to the web performance test context e.WebTest.Context.Add(this.ContextParameterName, myParam.ToString()); e.Success = true; return; } // If the extraction fails, set the error text that the user sees e.Success = false; e.Message = String.Format(CultureInfo.CurrentCulture, "Not Found: {0}", QueryName); } It's returning: System.Linq.Enumerable+<DistinctItem>d_81`1[system.string] I am expecting something along the lines of: 0152-1231-1231-123d My question is how do I extract the querystring's actual value from extractioneventargs. They say it's possible, but I have no idea.

  • Why doesn't IronRuby have the same tools that IronPython does?

    - by rsteckly
    Hi, I've been using Ruby as my main scripting language for years but switched to .NET several years ago. I'd like to continue using Ruby (primarily for testing) BUT the toolset for IronRuby is really nonexistent. Why? In Python, meanwhile, there are project templates and full intellisense support. Why isn't there something like that for IronRuby? The only thing I've been able to find on it is "there are no plans for VS integration at this time." Why???

  • Multiple infowindows - tearing my hair out

    - by thewinchester
    Ok, I'll admit I'm nowhere near the best programmer on the planet - and I'm used to the answer staring me right in the face but not making sense of it. Problem I need to display multiple markers on a map, each with their own infowindow. I have created the individual markers without a problem, but don't know how to create the infowindows for each. Steps so far I am generating a map using the V3 API within an ASP-based website, with markers being created from a set of DB records. The markers are created by looping through a rs and defining a marker() with the relevant variables: var myLatlng = new google.maps.LatLng(lat,long); var marker = new google.maps.Marker({ map: map, position: myLatlng, title: 'locationname', icon: 'http://google-maps-icons.googlecode.com/files/park.png' }); This is creating all the relevant markers in their correct locations. What I need to do now, and am not sure of how to achieve is give each of them their own unique infowindow which I can use to display information and links relevant to that marker. Source <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> <script language="javascript"> $(document).ready(function() { //Google Maps var myOptions = { zoom: 5, center: new google.maps.LatLng(-26.66, 122.25), mapTypeControl: false, mapTypeId: google.maps.MapTypeId.ROADMAP, navigationControl: true, navigationControlOptions: { style: google.maps.NavigationControlStyle.SMALL } } var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); <!-- While locations_haslatlong not BOF.EOF --> <% While ((Repeat1__numRows <> 0) AND (NOT locations_haslatlong.EOF)) %> var myLatlng = new google.maps.LatLng(<%=(locations_haslatlong.Fields.Item("llat").Value)%>,<%=(locations_haslatlong.Fields.Item("llong").Value)%>); var marker = new google.maps.Marker({ map: map, position: myLatlng, title: '<%=(locations_haslatlong.Fields.Item("ldescription").Value)%>', icon: 'http://google-maps-icons.googlecode.com/files/park.png', clickable: true, }); <% Repeat1__index=Repeat1__index+1 Repeat1__numRows=Repeat1__numRows-1 locations_haslatlong.MoveNext() Wend %> <!-- End While locations_haslatlong not BOF.EOF --> google.maps.event.addListener(marker, 'click', function() { infowindow.open(map,marker); }); google.maps.event.addListener(marker, 'dblclick', function() { map.setZoom(14); }); });

  • How do I backup my C++ Builder component installation?

    - by Gary Benade
    Hi I finally have my c++ Builder 2010 installation the way I want it, with all my components upgraded and installed. (touch wood) I have been working with c++builder since version 1 and I know from countless previous traumatic experiences that this state of affairs could change in an instant. I would like to backup the installation and component set. Is there a way to do this? A tool perhaps? A menu command that I have maybe missed all these years? I don't want to have to reinstall all the components from the bpl source again. I make nightly backup images of my entire drive, I would like to do this for c++builder only if possible. If it's a matter of simply copying files, which files would I need to copy? Are there entries in the registry that would need to be restored? Thanks in advance for any thoughts and suggestions

  • Win32 select/poll/eof/ANYTHING!?!?!

    - by Andrew
    Using the standard Win32 file I/O API's (CreateFile/ReadFile/etc), I'm trying to wait for a file to become readable, or for an exception to occur on the file. If Windows had any decent POSIX support, I could just do: select(file_count, files_waiting_for_read, NULL, files_waiting_for_excpt, NULL, NULL); And select will return when there's anything interesting on some of the files. Windows doesn't support select or poll. Fine. I figured I could take the file and do something like: while(eof(file_descriptor)) { Sleep(100); } The above loop would exit when more data is available to be read. But nope, Windows doesn't have an equivalent of eof() either! I could possibly call ReadFile() on the file, and determine if it's at the eof that way. But, then I'd have to handle the reading at that point in time -- I'm hoping to simply be able to figure out that a file is readable, without actually reading it. What are my options?

  • .Net assembly references being lost as soon as project is compiled

    - by Truegilly
    I have a windows service project, one of many C# projects in a solution file. I add a reference to my "Data_objects" class library for my windows service. this is added to the references no problem. all the classes become available and I can begin to code. As soon a I compile the windows service it says "The type or namespace name 'Data_Objects' could not be found (are you missing a using directive or an assembly reference?)" yet in the solution explorer the reference is fine, no yellow exclamation mark. I have to remove and add it again for it to pick it up, but then as soon as I compile it loses it. This reference works fine in my two other web application projects. what the hell is going on !! Truegilly Update there are no naming conflicts the only bit of code I have is a using statement - eg using Data_Objects.DataContext; also this only happens with a windows service project, i just created a new web app project and it works fine.

  • vs10 intellisense for jQuery

    - by justSteve
    I'm not able to get intellisense to work with javascript/jquery code in vs10. Not even getting highlighted opening/closing bracket and parens, much less autocomplete. In VS08 we had to install a patch to get intellisense for jquery. VS10 doesn't need that patch to support -vsdoc files. There was a bug in 08's intellisense that, if any of a project's included .js files had an error, we'd lose intellisense for javascript. That was supposed to be fixed in vs10. What the current set of troubleshooting steps to enable intellisense for VS10? thx

  • CLR SQL Assembly: Get the Bytestream?!

    - by OMG Ponies
    I have a SQL CLR dll I want to deploy, but have found you can embed the byte stream/varbinary_literal/ varbinary_expression/assembly bits into a text file to get around the messy hassle of packaging a DLL and making sure it's accessible for the CREATE ASSEMBLY command. But what I have yet to find is how to get that byte stream/varbinary_literal/ varbinary_expression/assembly bits value. I haven't found any consistent terminology, and what I keep finding in using Load(). Help?

  • the name 'controlname' does not exist in the current context

    - by zohair
    Hi, I have a web application that I'm working on(ASP.NET2.0 with C#)[Using VS2005]. Everything was working fine, and all of a sudden I get the error: Error 1 The name 'Label1' does not exist in the current context and 43 others of the sort for each time that I used a control in my codebehind of the page. This is only happening for 1 page. And it's as if the codebehind isn't recognizing the controls. Another interesting thing is that the intellisense isn't picking up any of the controls either.. I have tried to clean the solution file, delete the obj file, exclude the files from the project then re-add them, close VS and restart it, and even restart my computer, but none of these have worked. Please Help. Thank you

  • DLL Exports: not all my functions are exported

    - by carmellose
    I'm trying to create a Windows DLL which exports a number of functions, howver all my functions are exported but one !! I can't figure it out. The macro I use is this simple one : __declspec(dllexport) void myfunction(); It works for all my functions except one. I've looked inside Dependency Walker and here they all are, except one. How can that be ? What would be the cause for that ? I'm stuck. Edit: to be more precise, here is the function in the .h : namespace my { namespace great { namespace namespaaace { __declspec(dllexport) void prob_dump(const char *filename, const double p[], int nx, const double Q[], const double xlow[], const char ixlow[], const double xupp[], const char ixupp[], const double A[], int my, const double bA[], const double C[], int mz, const double clow[], const char iclow[], const double cupp[], const char icupp[] ); }}} And in the .cpp file it goes like this: namespace my { namespace great { namespace namespaaace { namespace { void dump_mtx(std::ostream& ostr, const double *mtx, int rows, int cols, const char *ind = 0) { /* some random code there, nothing special, no statics whatsoever */ } } // end anonymous namespace here // dump the problem specification into a file void prob_dump( const char *filename, const double p[], int nx, const double Q[], const double xlow[], const char ixlow[], const double xupp[], const char ixupp[], const double A[], int my, const double bA[], const double C[], int mz, const double clow[], const char iclow[], const double cupp[], const char icupp[] ) { std::ofstream fout; fout.open(filename, std::ios::trunc); /* implementation there */ dump_mtx(fout, Q, nx, nx); } }}} Thanks

  • % style macros not supported in some C++/CLI project property pages under VS2010?

    - by Dave Foster
    We're currently evaluating VS2010 and have upgraded our VS2008 C++/CLI project to the new .vcxproj format. I've noticed that a certain property we had set in the project settings did not get translated properly. Under Configuration Properties - Managed Resources - Resource Logical Name, we used to have (in VS2008) the setting: $(IntDir)\$(RootNamespace).$(InputName).resources which indicated that all .resx files were to compile into OurLib.SomeForm.resources inside of the assembly. (the Debug portion is dropped when assembled) According to MSDN, the $(InputName) macro no longer exists and should be replaced with %(Filename). However, when translating the above line to swap those macros, it does not seem to ever expand. The second .resx file it tries to compile, I get a "LINK : fatal error LNK1316: duplicate managed resource name 'Debug\OurLib.%(Filename).resources". This indicates to me that the % style macros are not being expanded here, at least in this specific property. If we don't set anything in that property, the default behavior seems to be to add the subdirectory as a prefix, such as: OurLib.Forms.SomeForm.resources where Forms is the subdir of our project that the .resx file lives. This only occurs when the .resx file is in an immediate subdirectory of the project being built. If a .resx file exists somewhere else on disk (aka ..\OtherLib\Forms\SomeForm2.resx) this prefix is NOT added. This is causing an issue with loading form resources, as it does not account for this possible prefix, even though we are using the standard Forms Designer method of getting at resources: System::ComponentModel::ComponentResourceManager^ resources = (gcnew System::ComponentModel::ComponentResourceManager(SomeForm::typeid)); and do not specify the .resources file by name. The issue I've just described may not be the same as the original question, but if I were to fix the Resource Logical Name issue I think this would all go away. Does anyone have any information about these % macros and where they are allowed to be used?

  • Global resources can't be resolved after publishing Website in VS2008

    - by Scoregraphic
    Hi there I have a web-project running in VS 2008. We have some global resource files (*.resx) in the App_GlobalResources folder for internationalisation. All this works like a charm on my local IIS installation out of VS. But when I publish my web-project to the local filesystem and/or another server, all the resources can no longer be found. So I guess the pre-compilation is somehow corrupting stuff. When I call the pre-compiled web, I get an error that the resource object with key xyz cannot be found, although it could be found before. I checked with .NET reflector if the resource stuff made it into the *.dlls. All those identifiers are there (bin/Web.dll, bin/<culture>/Web.resources.dll). The identifiers are loaded like this: <asp:MenuItem NavigateUrl="~/OrderNew.aspx" Text="<%$ Resources:MyProject, MenuNewOrder %>" Value="NewOrder"> The resource files are called MyProject.resx and MyProject.<culture>.resx where <culture> corresponds the the specific culture (i.e. MyProject.de-DE.resx). Any ideas how to solve this? I really appreciate any help. Thanks Edit: If I copy the App_GlobalResources folder manually to the output, the resources may be loaded normally. So I really really wonder what this pre-compilation is all about. I'm still interested in solving the issue "the right way".
