• Help using RDA on a Desktop Applicaton?

  - by Joel

  I have a .NET 3.5 Compact Framework project that uses RDA for moving data between its mobile device's local SqlCe database and a remote MSSql-2008 server(it uses RDA Push and Pull). The server machine a virtual directory with sqlcesa35.dll (v3.5.5386.0) setup for RDA. We usually install these cabs on the mobile devices and the RDA process does not have any problems: sqlce.wce5.armv4i.cab sqlce.repl.wce5.armv4i.cab Now I am trying to run this application as a desktop application. RDA Pull (download) has been working well. But the RDA Push (upload) is giving me some problems. This is the exception that I get on the desktop application when I try to use RDA Push: System.Data.SqlServerCe.SqlCeException The Client Agent and Server Agent component versions are incompatible. The compatible versions are: Client Agent versions 3.0 and 3.5 with Server Agent versions 3.5 and Client Agent version 3.5 with Server Agent version 3.5. Re-install the replication components with the matching versions for client and server agents. [ 35,30,Client Agent version = ,Server Agent version = ] I have tried copying the file C:\Program Files\Microsoft SQL Server Compact Edition\v3.5\Desktop\SqlServerCe.dll (v3.5.5692.0) to bin\debug I have also tried copying another version of SqlServerCe.dll (v3.0.5206.0) to bin\debug. But this just gives me a slightly different exception: System.Data.SqlServerCe.SqlCeException [ 35,30 ] Is there a different setup or any different dlls that I need to use? Thanks, -Joel

• Complete failure to compile when include CSS Friendly Adapters

  - by david

  Background - I am trying to use the friendly adapters to override the default styling for the standard asp.net menu control that is used by an existing project. The existing project functions normally and compiles when requested without incident. Adding in the code for the for the CSS Friendly adapter and not only does it not compile, but it never even really starts. The Problem in Detail - I am using the sample code from Scott on this page: http://weblogs.asp.net/scottgu/archive/2006/09/08/CSS-Control-Adapter-Toolkit-Update.aspx. The sample project compiles fine, just within the existing project does it fail. Fails without a line number or any other traceable info. It definately appears to be related to the CSSMenuAdapter.browser file, which has been referenced by others online as the cause of similar error. I have tried addind and readding, using as a dll, using as a code file in app code, etc. I am working with aspdotnetstorefront in this case, although it is not unique to them as I have found other references in software packages online. Only thing is, no one ever says what solved the issue. I am using Windows 7, VS2008 Express and SQL Express 2008 R2. The full error msg is: Error 10 Exception of type 'System.OutOfMemoryException' was thrown. Notice that there is no file, line, or column info. Really need some help here. I have been working on this a long time. This really should have tag: cssfriendlyadapter but I could not create that.

• Anonymous union definition/declaration in a macro GNU vs VS2008

  - by Alan_m

  I am attempting to alter an IAR specific header file for a lpc2138 so it can compile with Visual Studio 2008 (to enable compatible unit testing). My problem involves converting register definitions to be hardware independent (not at a memory address) The "IAR-safe macro" is: #define __IO_REG32_BIT(NAME, ADDRESS, ATTRIBUTE, BIT_STRUCT) \ volatile __no_init ATTRIBUTE union \ { \ unsigned long NAME; \ BIT_STRUCT NAME ## _bit; \ } @ ADDRESS //declaration //(where __gpio0_bits is a structure that names //each of the 32 bits as P0_0, P0_1, etc) __IO_REG32_BIT(IO0PIN,0xE0028000,__READ_WRITE,__gpio0_bits); //usage IO0PIN = 0x0xAA55AA55; IO0PIN_bit.P0_5 = 0; This is my comparable "hardware independent" code: #define __IO_REG32_BIT(NAME, BIT_STRUCT)\ volatile union \ { \ unsigned long NAME; \ BIT_STRUCT NAME##_bit; \ } NAME; //declaration __IO_REG32_BIT(IO0PIN,__gpio0_bits); //usage IO0PIN.IO0PIN = 0xAA55AA55; IO0PIN.IO0PIN_bit.P0_5 = 1; This compiles and works but quite obviously my "hardware independent" usage does not match the "IAR-safe" usage. How do I alter my macro so I can use IO0PIN the same way I do in IAR? I feel this is a simple anonymous union matter but multiple attempts and variants have proven unsuccessful. Maybe the IAR GNU compiler supports anonymous unions and vs2008 does not. Thank you.

• Deserialize complex JSON (VB.NET)

  - by Ssstefan

  I'm trying to deserialize json returned by some directions API similar to Google Maps API. My JSON is as follows (I'm using VB.NET 2008): jsontext = { "version":0.3, "status":0, "route_summary": { "total_distance":300, "total_time":14, "start_point":"43", "end_point":"42" }, "route_geometry":[[51.025421,18.647631],[51.026131,18.6471],[51.027802,18.645639]], "route_instructions": [["Head northwest on 43",88,0,4,"88 m","NW",334.8],["Continue on 42",212,1,10,"0.2 km","NW",331.1,"C",356.3]] } So far I came up with the following code: Dim js As New System.Web.Script.Serialization.JavaScriptSerializer Dim lstTextAreas As Output_CloudMade() = js.Deserialize(Of Output_CloudMade())(jsontext) I'm not sure how to define complex class, i.e. Output_CloudMade. I'm trying something like: Public Class RouteSummary Private mTotalDist As Long Private mTotalTime As Long Private mStartPoint As String Private mEndPoint As String Public Property TotalDist() As Long Get Return mTotalDist End Get Set(ByVal value As Long) mTotalDist = value End Set End Property Public Property TotalTime() As Long Get Return mTotalTime End Get Set(ByVal value As Long) mTotalTime = value End Set End Property Public Property StartPoint() As String Get Return mStartPoint End Get Set(ByVal value As String) mStartPoint = value End Set End Property Public Property EndPoint() As String Get Return mEndPoint End Get Set(ByVal value As String) mEndPoint = value End Set End Property End Class Public Class Output_CloudMade Private mVersion As Double Private mStatus As Long Private mRSummary As RouteSummary 'Private mRGeometry As RouteGeometry 'Private mRInstructions As RouteInstructions Public Property Version() As Double Get Return mVersion End Get Set(ByVal value As Double) mVersion = value End Set End Property Public Property Status() As Long Get Return mStatus End Get Set(ByVal value As Long) mStatus = value End Set End Property Public Property Summary() As RouteSummary Get Return mRSummary End Get Set(ByVal value As RouteSummary) mRSummary = value End Set End Property 'Public Property Geometry() As String ' Get ' End Get ' Set(ByVal value As String) ' End Set 'End Property 'Public Property Instructions() As String ' Get ' End Get ' Set(ByVal value As String) ' End Set 'End Property End Class but it does not work. The problem is with complex properties, like route_summary. It is filled with "nothing". Other properties, like "status" or "version" are filled properly. Any ideas, how to define class for the above JSON? Can you share some working code for deserializing JSON in VB.NET? Thanks,

• How to distribute an offline cube for excel

  - by Mike M

  I have the following scenario. A cube created in SSAS 2008. I can connected to this cube via Excel. I can create an offline cube file. I can connect to this offline cube file. Now, say I want to email this excel file along with the cube file so that another user can view it. I run into the problem that the connection path the offline cube is hard coded into the excel file. Its the same problem this person had. http://stackoverflow.com/questions/1253950/opening-offline-cube-from-another-machine Their solution was to just make sure the other user saved the cube in the same directory structure. I don't love that solution. I also came across this idea: http://www.pcreview.co.uk/forums/thread-948974.php I tried that, it errored out, but I am not an Excel VBA programmer and really have no idea if I even put the code in the right place. So anyway, anyone out there have any ideas about who to do this? If the VBA solution is the best, could someone give me some tips on where to actually put that code?

• Can a stateless WCF service benefit from built-in database connection pooling?

  - by vladimir

  I understand that a typical .NET application that accesses a(n SQL Server) database doesn't have to do anything in particular in order to benefit from the connection pooling. Even if an application repeatedly opens and closes database connections, they do get pooled by the framework (assuming that things such as credentials do not change from call to call). My usage scenario seems to be a bit different. When my service gets instantiated, it opens a database connection once, does some work, closes the connection and returns the result. Then it gets torn down by the WCF, and the next incoming call creates a new instance of the service. In other words, my service gets instantiated per client call, as in [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]. The service accesses an SQL Server 2008 database. I'm using .NET framework 3.5 SP1. Does the connection pooling still work in this scenario, or I need to roll my own connection pool in form of a singleton or by some other means (IInstanceContextProvider?). I would rather avoid reinventing the wheel, if possible.

• Global.asax parser errors when deploying MVC 1 application to remote server.

  - by mannish

  So we're having some issues deploying an ASP.NET MVC app to a client site. Basically when we try to test the app from localhost, we get the dreaded Global.asax parser error indicating it could not load the application global. Research indicates there are basically 4 possible reasons for this exception we're seeing: The solution hasn't been built. This clearly isn't the case since we can deploy it here and it runs fine on any machine we deploy to AND we had to build and publish the darn thing to deploy it anyway. The Global.asax namespace inheritance does not match the application global code file. Again we double checked this and since it runs just fine here that can't be the issue. Miscellaneous non-descript IIS/VS.NET mischief. Basically something get's wonky in IIS or VS.NET and the web server won't behave correctly for this application. We've done cleans and rebuilds, we've deleted virtual dir and recreated, and performed all of the IIS munging that we've found elsewhere online. Various combinations of IIS bounces, server reboots, virtual dir/application recreation, etc. Code level permissions issue. We've verified full trust in machine/web config in the framework directory, we've set .NET trust to full in IIS, we've granted Everyone full control on the directories just to hit it with the security hammer, etc. etc. The pertinent detials: Windows Server 2008 x64 IIS 7, 32 bit compatible app pool (app was written on 32 bit OS compiled for any cpu) App pool identity set to NetworkService Microsoft ASP.NET MVC 1.0 XCopy deployment We deployed another read-only app just fine. The significant difference in this app is the use of NHibernate and Log4Net which require full trust. Additionally, the actual project name of the web project differs from the default namespace however the Inherits namespace in Global.asax and the Global.asax.cs files match so this shouldn't be an issue. Anybody have any bright ideas? We're officially down to just the dim ones.

• Excel Automation Addin UDFs not accesible

  - by Eric

  I created the following automation addin: namespace AutomationAddin { [Guid("6652EC43-B48C-428a-A32A-5F2E89B9F305")] [ClassInterface(ClassInterfaceType.AutoDual)] [ComVisible(true)] public class MyFunctions { public MyFunctions() { } #region UDFs public string ToUpperCase(string input) { return input.ToUpper(); } #endregion [ComRegisterFunctionAttribute] public static void RegisterFunction(Type type) { Registry.ClassesRoot.CreateSubKey( GetSubKeyName(type, "Programmable")); RegistryKey key = Registry.ClassesRoot.OpenSubKey( GetSubKeyName(type, "InprocServer32"), true); key.SetValue("", System.Environment.SystemDirectory + @"\mscoree.dll", RegistryValueKind.String); } [ComUnregisterFunctionAttribute] public static void UnregisterFunction(Type type) { Registry.ClassesRoot.DeleteSubKey( GetSubKeyName(type, "Programmable"), false); } private static string GetSubKeyName(Type type, string subKeyName) { System.Text.StringBuilder s = new System.Text.StringBuilder(); s.Append(@"CLSID\{"); s.Append(type.GUID.ToString().ToUpper()); s.Append(@"}\"); s.Append(subKeyName); return s.ToString(); } } } I build it and it registers just fine. I open excel 2003, go to tools-Add-ins, click on the automation button and the addin appears in the list. I add it and it shows up in the addins list. but, the functions themselves don't appear. If I type it in it doesn't work and if I look in the function wizard, my addin doesn't show up as a category and the functions are not in the list. I am using excel 2003 on windows 7 x86. I built the project with visual studio 2010. This addin worked fine on windows xp built with visual studio 2008.

• Launch command on remote Windows machine, given admin credentials

  - by Bilal Aslam

  I have a Windows Server 2008 instance on Amazon EC2 (Amazon's cloud compute platform, which provides VMs in the cloud). It has an external IP, and I have an admin account on the box. I would like to 'bootstrap' this instance remotely i.e. I want to run commands to download, install and configure apps on it, all without having to log on even once. I have figured out how to do this to a remote, domain-joined computer using WMI. I can even use psexec to get what I want, as long as the remote computer is part of the domain. However, I have NOT been able to do for a remote computer on EC2. Here are some specific restrictions: 1) The remote computer is not part of my domain, hence no Kerberos 2) The remote computer does not have a cert I trust, or vice versa I am sure I am running into to some auth/trust restriction. Is there any way I can run a single command on the remote, given that I have admin privileges? I'm not tied down to using WMI, but I do need to run a command somehow. Feels like this should be a solved problem.

• Problem using structured data with sproxy-generated proxy c++ class

  - by Odrade

  I am attempting to communicate structured data types between a Visual C++ client application and an ASP.NET web service. I'm am having issues whenever any parameter or return type is not a basic type (e.g. string, int, float, etc). To illustrate the issue, I created the following ASP.NET web service: namespace TestWebService { [WebService(Namespace = "http://localhost/TestWebService")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [ToolboxItem(false)] public class Service1 : System.Web.Services.WebService { [WebMethod] public TestData StructuredOutput() { TestData td = new TestData(); td.data = 1729; return td; } } public class TestData { public int data; } } To consume the service, I created a dirt-simple Visual C++ client in VS2005. I added a web reference to the project, which caused sproxy to generate a proxy class for me. With the generated header properly included, I attempted to invoke the service like this: int _tmain(int argc, _TCHAR* argv[]) { CoInitialize(NULL); Service1::CService1 ws; Service1::TestData td; HRESULT hr = ws.StructuredOutput(&td); //data is returned as expected CoUninitialize(); return 0; } // crashes here with access violation The call to StructuredOutput returns the data as expected, but an access violation occurs on destruction of the CService1 object. The access violation is occurring here (from atlsoap.h): void UninitializeSOAP() { if (m_spReader.p != NULL) { m_spReader->putContentHandler(NULL); //access violation m_spReader.Release(); } } I see the same behavior when using a TestData object as an input parameter, or when using any other structured data types as input or output. When I use basic types for input/output from the web service I do not experience these errors. Any ideas about why this might be happening? Is sproxy screwing something up, or am I? NOTE: I'm aware of gSOAP and the wsdl2h tool, but those aren't freely available for commercial use (and nobody here is going to buy a license). I am open to alternatives for generating the c++ proxy, as long as they are free for commercial use.

• Sql Exception: Error converting data type numeric to numeric

  - by Lucifer

  Hello We have a very strange issue with a database that has been moved from staging to production. The first time the database was moved it was by detaching, copying and reattaching, the second time we tried restoring from a backup of the staging. Both SQL Servers are the same version of MS SQL 2008, running on 64 bit hardware. The code accessing the database is the same build, built using the .net 2.0 framework. Here is the error message and some of the stack trace: Exception Details: System.Data.SqlClient.SqlException: Error converting data type numeric to numeric.

• TeamCity output artifacts not published to IIS7 folder

  - by clausas

  I am trying to set up TeamCity to build and deploy an ASP.NET MVC application. I have the setup running successfully on other servers using TeamCity 4.5, but the new server is running TeamCity 6, and I am having trouble getting it to work as expected. TeamCity manages to get the files from source control, and the project (Visual Studio Solution 2008 set to "Build") builds and outputs the necessary files as expected. The problem seems to be with my artifact paths, as the output files are not copied to the website folder. My solution consists of dozen projects, of which the "Web" project is the interesting one in this case. The build checkout directory is C:\TeamCity\buildAgent\work\7da320cebf0ee541, and the "Web"-project is found in C:\TeamCity\buildAgent\work\7da320cebf0ee541\Web I have set up my build configuration with the following artifact paths (relative from checkout directory to the folder containing the website): Web/bin=>../../../../inetpub/wwwroot/staging/bin Web/Content=>../../../../inetpub/wwwroot/staging/Content Web/Views=>../../../../inetpub/wwwroot/staging/Views Web/Media=>../../../../inetpub/wwwroot/staging/Media Web/*.aspx=>../../../../inetpub/wwwroot/staging Web/*.asax=>../../../../inetpub/wwwroot/staging (I've tried with more ../ just in case, but it didn't make a difference). This is the output I get from the log [19:35:29]: Publishing artifacts (1s) [19:35:29]: [Publishing artifacts] Paths to publish: [Web/bin=../../../../inetpub/wwwroot/staging/bin, Web/Content=../../../../inetpub/wwwroot/staging/Content, Web/obj=../../../../inetpub/wwwroot/staging/obj, Web/Views=../../../../inetpub/wwwroot/staging/Views, Web/Media=../../../../inetpub/wwwroot/staging/Media, Web/.aspx=../../../../inetpub/wwwroot/staging, Web/.asax=../../../../inetpub/wwwroot/staging, teamcity-info.xml] [19:35:30]: [Publishing artifacts] Sending files [19:35:32]: Build finished Logs from some of the other servers running TeamCity 4.5 uses a different format, with a line for each of the artifacts being published, I'm not sure if this is relevant or only due to a different logging format. Everything seems to be working, but no files are put in my website folder after a build, am I missing something here? Any help will be much appreciated :)

• How do I Data-Bind dual DateTimePicker to a single DateTime object

  - by S.C. Madsen

  Hi, I have a simple form, with two DateTimePicker-controls: One for date, and one for time. The thing is these two controls are supposed to represent a single point in time. Hence I would like to "Bind" them to a single DateTime property on my form (for simplicity). I did the following: // Start is a DateTime property on the form _StartDate.DataBindings.Add("Value", this, "Start"); _StartTime.DataBindings.Add("Value", this, "Start"); But hooking into "ValueChanged" event, yields mixed results... Sometimes I get exactly what I want, sometimes the updates of the property are "sluggish". I figured this way of splitting into two DateTimePicker's was fairly common. So how to do it? Update: There is possibly multiple questions in there: How do I bind a DateTimePicker (Format: Date) to a DateTime Property on a form? Then, how do I bind yet another DateTimePicker (Format: Time) to the same property? I'm using Visual Studio Express 2008 (.NET 3.5), and I seemingly get ValueChanged events from the DateTimePickers before the value is changed?

  Hi, as stated in subject, i have an image: private Image testing; testing = new Bitmap(@"sampleimg.jpg"); I would like to split it into 3 x 3 matrix meaning 9 images in total and save it.Any tips or tricks to do this simple? I'm using visual studios 2008 and working on smart devices. Tried some ways but i can't get it. This is what i tried: int x = 0; int y = 0; int width = 3; int height = 3; int count = testing.Width / width; Bitmap bmp = new Bitmap(width, height); Graphics g = Graphics.FromImage(bmp); for (int i = 0; i < count; i++) { g.Clear(Color.Transparent); g.DrawImage(testing, new Rectangle(0, 0, width, height), new Rectangle(x, y, width, height), GraphicsUnit.Pixel); bmp.Save(Path.ChangeExtension(@"C\AndrewPictures\", String.Format(".{0}.bmp",i))); x += width; }

• Architecture for new ASP.NET web application

  - by Anders Abel

  I'm maintaining an application which currently is just a web service (built with WCF) and a database backend. The web service is built in layers with a linq-to-sql data access part with core functionality in an own assembly and on top of that the web service assembly which contains the WCF code. The core assembly also handles all business logic rules (very few actually). The customer now wants a Web interface for the application instead of just accessing it through other applications which are consuming the web service. I'm quite lost on modern web application design, so I would like some advice on what architecture and frameworks to use for the web application. The web application will be using the same core assembly with business rules and the linq-to-sql data access layer as the web service. Some concepts I've thought about are: ASP.NET MVC Webforms AJAX controls - possibly leting the AJAX controls access the existing web service through JSON. Are there any more concepts I should look into? Which one is the best for a fresh project? The development tools are Visual Studio 2008 Team Edition for Developers targeting .NET 3.5. An upgrade to Visual Studio 2010 Premium (or maybe even Ultimate) is possible if it gives any benefits.

• C++ LPTSTR to int (but memory overwrite problem using atoi)

  - by Dexter

  I have the following code, m_edit is a MFC CEdit (I know I would never use MFC but project demanded it). It's a simple loop, that gets the text from a text edit, converts it to integer after getting the first line, then stores it in m_y vector. LPTSTR szTemp; vector<int> m_y; for(int i = 0; i < m_edit->GetLineCount(); i++){ szTemp = s_y.GetBuffer(0); m_edit->GetLine(i, szTemp); // get line text store in szTemp y = atoi(szTemp); m_y.push_back(y); szTemp = ""; y = 0; } IMPORTANT EXAMPLE: So let's say the CEdit has 6 numbers: 0 5 2 5 18 6 If you use Visual Studio's debugger you will notice an anomaly!! Here's what it shows: y = 0 y = 5 y = 2 y = 5 y = 18 y = 68 Do you see that? szTemp when inserted into atoi, it returns the number 6, but concatenates the 2nd digit of the last number!!! This is why I did szTemp = "";, but the problem persists. Also, let's say the last number was 17 (not 18), then this time debugger would say y = 67, so it is definitely this problem. However, Visual Studio debugger, when you hover over szTemp during this iteration, it says '6' <--- not '68' inside szTemp. So somehow atoi is ruining it. Am I suppose to concatenate a \0 into szTemp before putting it into atoi? How do I solve this easily?

• How to install Eclipse + PHP Development Tools (PDT) + Debugger on Mac in The Year 2010

  - by aphex5

  I had a lot of trouble installing Eclipse and PDT on my system. It took two days, largely because all the tutorials I could find were out of date (written in 2008, it's 2010 now) and various steps they included were no longer necessary, broken, or irrelevant. I wanted to write my process here so it could be improved upon (via wiki) as time goes on. Install Eclipse without PHP plugin ("Eclipse Classic"). This will give you a complete Eclipse, which I find preferable, as the UI is more fleshed out (e.g. you get a default list of Perspectives, which helps you understand what Perspectives are.) Install PDT SDK with the Help Install New Software menu item. You'd think you'd be done here, but if you try to run something, it'll fail complaining of not having a debugger. Install the Zend Debugger. It'll fail if you try to use the Install New Software option, as many tutorials suggest ("No repository found containing osgi.bundle.org.zend.php.debug.debugger.5.3.7.v20091116".) Instead, download it from http://www.zend.com/en/community/pdt, and manually copy the features/ and plugins/ directory into your Eclipse install (these instructions are not written anywhere). Restart Eclipse Monkey with preferences for a while -- if you followed a previous tutorial and tried to manually add your php executable to Eclipse prefs (/usr/bin/php), remove it (PHP PHP Executables). Set one of the Zend Debugger executables to the default. If you've already tried to execute a .php file, remove the existing "Run" profile you (maybe weren't aware that you) created (Run Debug Configurations...). Eclipse works! You should be able to run a .php file as a script just fine.

• Deep copy objects from different namespaces

  - by Wasim

  Hi all, I have the following situation: I have class User with the follwing properies : public class User { string user name ; List <Contact> contacts ; List <BookMark> book marks; . . . } I have the same class in a different namespace , with some different properties . BWT , it's the same situation of it's classes (Contact) and (BookMark). I need to make a deep copy of the same properties from the two classes . Actually , I arrive to this situation by having an Entity Framework edmx file . I created the first database (SQL server 2008) from this model . And copied he same edmx file to another project and created the database with SQL CE db. Now I get the first data model objects by WCF service and need to persist them in the local database in my application . The objects are the same but there are some changs because of the modeling issue with a different databse. Do you have any workarround about this assue. Thanks in advance ...

• Bizarre Javascript JSON undefined error

  - by Nate C-K

  I'm experiencing an error that I haven't been able to find any mention of anywhere. I'm developing an AJAX-enabled WCF web service with ASP.NET. In my ASP.NET master page's , I included the json.js file, copied fresh from json.org. When I run the page, it fails (VS 2008 catches a Javascript exception) on the first line of code in json.js (following lots of comments), which is: JSON = JSON || {}; The error says that JSON is undefined: Microsoft JScript runtime error: 'JSON' is undefined Well, duh! That's why the line is testing if it's defined and if so setting it to an empty object! It is supposed to be undefined, right? Last I heard it was not an error in Javascript to perform such an operation on an undefined variable. Can anyone give me a clue as to what's going on here? I suspect it's something gone wrong elsewhere that's somehow causing this problem. I don't have deep experience with either Javascript or ASP.NET so it might be that I'm missing some common gotcha in the setup.

• Float compile-time calculation not happening?

  - by Klaim

  A little test program: #include <iostream> const float TEST_FLOAT = 1/60; const float TEST_A = 1; const float TEST_B = 60; const float TEST_C = TEST_A / TEST_B; int main() { std::cout << TEST_FLOAT << std::endl; std::cout << TEST_C << std::endl; std::cin.ignore(); return 0; } Result : 0 0.0166667 Tested on Visual Studio 2008 & 2010. I worked on other compilers that, if I remember well, made the first result like the second result. Now my memory could be wrong, but shouldn't TEST_FLOAT have the same value than TEST_C? If not, why? Is TEST_C value resolved at compile time or at runtime? I always assumed the former but now that I see those results I have some doubts...

• How do I get ASP.NET login status controls to display a Log In option?

  - by Greg McNulty

  I have the following log in status controls on the top of my master page. It displays the logged in as, manager log in, and Log out options. However, when a user is not logged in, there is nothing displayed there. When the user is NOT logged in, is there a way to display a "Login" text link that takes you to the log in page and then "disappears" once the user is logged in? Any help is appreciated. Thanks! <asp:LoginName ID="LoginName1" runat="server" FormatString="Logged in as {0}" ForeColor="Aqua" /> <asp:LoginView ID="LoginView1" runat="server"> <RoleGroups> <asp:RoleGroup Roles="Managers"> <ContentTemplate> <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl="~/Management/management.aspx">Manage Site</asp:HyperLink> or <asp:LoginStatus id="LoginStatus1" runat="server" /> </ContentTemplate> </asp:RoleGroup> </RoleGroups> <LoggedInTemplate> (<asp:LoginStatus id="LoginStatus1" runat="server" />) </LoggedInTemplate> </asp:LoginView> ASP.NET 3.5 VWD 2008 C#

• Sending jpegs by tcp socket...sometimes incomplete.

  - by Guy

  Vb.net Hi I've been working on a project for months now (vb 2008 express). There is one final problem which I can't solve. I need to send images to a client from a 'server'(listener). The code below works most of the time but sometimes the image is incomplete. I believe this might be something to do with the tcp packet sizes varying, maybe limited by how busy it is out there on the net. I have seen examples of code that splits the image into chunks and sends them out, but I can't get them to work maybe because I'm using a different vb version. The pictures to be sent are small 20k max. Any working code examples would be wonderful. I have been experimenting and failing with this final hurdle for weeks. Thanks in anticipation.
