  • How do I correctly install dulwich to get hg-git working on Cygwin?

    - by Erik Vold
    I have a similar issue as in this issue, but in my case I am trying to use cygwin. First I followed the instructions here, and I ran: $ easy_install hg-git The I created ~/.hgrc, with: [extensions] hgext.bookmarks = hggit = Then when I typed 'hg' at a command prompt, I'd see: "* failed to import extension hggit: No module named hggit" So I did a search for "hggit" and found /cygdrive/c/Python26/Lib/site-packages/hg_git-0.2.1-py2.6.egg/hggit, so I updated .hgrc: [extensions] hgext.bookmarks = hggit = /cygdrive/c/Python26/Lib/site-packages/hg_git-0.2.1-py2.6.egg/hggit Then when I type 'hg' I get "No module named dulwich.errors" If you read this question, it's the same problem. In python shell I cannot import dulwich: >>> import dulwich Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named dulwich I checked out my easy-install.pth and it does contain the dulwich egg: import sys; sys.__plen = len(sys.path) ./hg_git-0.2.1-py2.6.egg ./dulwich-0.5.0-py2.6-win32.egg import sys; new=sys.path[sys.__plen:]; del sys.path[sys.__plen:]; p=getattr(sys,'__egginsert',0); sys.path[p:p]=new; sys.__egginsert = p+len(new) So how can I fix this so that import dulwich works, which should fix my problem using hg-git I assume..

  • Performance problem with System.Net.Mail

    - by Saif Khan
    I have this unusual problem with mailing from my app. At first it wasn't working (getting unable to relay error crap) anyways I added the proper authentication and it works. My problem now is, if I try to send around 300 emails (each with a 500k attachment) the app starts hanging around 95% thru the process. Here is some of my code which is called for each mail to be sent Using mail As New MailMessage() With mail .From = New MailAddress(My.Resources.EmailFrom) For Each contact As Contact In Contacts .To.Add(contact.Email) Next .Subject = "Accounting" .Body = My.Resources.EmailBody 'Back the stream up to the beginning orelse the attachment 'will be sent as a zero (0) byte file. attachment.Seek(0, SeekOrigin.Begin) .Attachments.Add(New Attachment(attachment, String.Concat(Item.Year, Item.AttachmentType.Extension))) End With Dim smtp As New SmtpClient("192.168.1.2") With smtp .DeliveryMethod = SmtpDeliveryMethod.Network .UseDefaultCredentials = False .Credentials = New NetworkCredential("username", "password") .Send(mail) End With End Using With item .SentStatus = True .DateSent = DateTime.Now.Date .Save() End With Return I was thinking, can I just prepare all the mails and add them to a collection then open one SMTP conenction and just iterate the collection, calling the send like this Using mail As New MailMessage() ... MailCollection.Add(mail) End Using ... Dim smtp As New SmtpClient("192.168.1.2") With smtp .DeliveryMethod = SmtpDeliveryMethod.Network .UseDefaultCredentials = False .Credentials = New NetworkCredential("username", "password") For Each mail in MainCollection .Send(mail) Next End With

  • Is using the .NET Image Conversion enough?

    - by contactmatt
    I've seen a lot of people try to code their own image conversion techniques. It often seems to be very complicated, and ends up using GDI+ function calls, and manipulating bits of the image. This has got me wondering if I am missing something in the simplicity of .NET's image conversion call when saving an image. Here's the code I have: Bitmap tempBmp = new Bitmap("c:\temp\img.jpg"); Bitmap bmp = new Bitmap(tempBmp, 800, 600); bmp.Save(c:\temp\img.bmp, //extension depends on format ImageFormat.Bmp) //These are all the ImageFormats I allow conversion to within the program. Ignore the syntax for a second ;) ImageFormat.Gif) //or ImageFormat.Jpeg) //or ImageFormat.Png) //or ImageFormat.Tiff) //or ImageFormat.Wmf) //or ImageFormat.Bmp)//or ); This is all I'm doing in my image conversion. Just setting the location of where the image should be saved, and passing it an ImageFormat type. I've tested it the best I can, but I'm wondering if I am missing anything in this simple format conversion, or if this is sufficient?

  • Context menu event handling error - CS1061

    - by MrTemp
    I am still new to c# and wpf This program is a clock with different view and I would like to use the context menu to change between view, but the error says that there is no definition or extension method for the events. Right now I have the event I'm working on popping up a MessageBox just so I know it has run, but I cannot get it to compile. public partial class MainWindow : NavigationWindow { public MainWindow() { //InitializeComponent(); } public void AnalogMenu_Click(object sender, RoutedEventArgs e) { /*AnalogClock analog = new AnalogClock(); this.NavigationService.Navigate(analog);*/ } public void DigitalMenu_Click(object sender, RoutedEventArgs e) { MessageBox.Show("Digital Clicked"); /*DigitalClock digital = new DigitalClock(); this.NavigationService.Navigate(digital);*/ } public void BinaryMenu_Click(object sender, RoutedEventArgs e) { /*BinaryClock binary = new BinaryClock(); this.NavigationService.Navigate(binary);*/ } } and the xaml call if you want it <NavigationWindow.ContextMenu> <ContextMenu Name="ClockMenu" > <MenuItem Name="ToAnalog" Header="To Analog" ToolTip="Changes to an analog clock"/> <MenuItem Name="ToDigital" Header="To Digital" ToolTip="Changes to a digital clock" Click="DigitalMenu_Click" /> <MenuItem Name="ToBinary" Header="To Binary" ToolTip="Changes to a binary clock"/> </ContextMenu> </NavigationWindow.ContextMenu>

  • C# .Net Serial DataReceived Event response too slow for high-rate data.

    - by Matthew
    Hi, I have set up a SerialDataReceivedEventHandler, with a forms based program in VS2008 express. My serial port is set up as follows: 115200, 8N1 Dtr and Rts enabled ReceivedBytesThreshold = 1 I have a device I am interfacing with over a BlueTooth, USB to Serial. Hyper terminal receives the data just fine at any data rate. The data is sent regularly in 22 byte long packets. This device has an adjustable rate at which data is sent. At low data rates, 10-20Hz, the code below works great, no problems. However, when I increase the data rate past 25Hz, there starts to recieve mulitple packets on one call. What I mean by this is that there should be a event trigger for every incoming packet. With higher output rates, I have tested the buffer size (BytesToRead command) immediatly when the event is called and there are multiple packets in the buffer then. I think that the event fires slowly and by the time it reaches the code, more packes have hit the buffer. One test I do is see how many time the event is trigger per second. At 10Hz, I get 10 event triggers, awesome. At 100Hz, I get something like 40 event triggers, not good. My goal for data rate is 100HZ is acceptable, 200Hz preferred, and 300Hz optimum. This should work because even at 300Hz, that is only 52800bps, less than half of the set 115200 baud rate. Anything I am over looking? public Form1() { InitializeComponent(); serialPort1.DataReceived += new SerialDataReceivedEventHandler(serialPort1_DataReceived); } private void serialPort1_DataReceived(object sender, SerialDataReceivedEventArgs e) { this.Invoke(new EventHandler(Display_Results)); } private void Display_Results(object s, EventArgs e) { serialPort1.Read(IMU, 0, serial_Port1.BytesToRead); }

  • Error CS0117: Namespace.A does not contain definition for Interface..

    - by SnOrfus
    I'm getting the error: 'Namespace.A' does not contain a definition for 'MyObjectInterface' and no extension method 'MyObjectInterface' accepting a first argument of type ... I've looked at this and this and neither seems to apply. The code looks like: public abstract class Base { public IObject MyObjectInterface { get; set; } } public class A : Base { /**/ } public class Implementation { public void Method() { Base obj = new A(); obj.MyObjectInterface = /* something */; // Error here } } IObject is defined in a separate assembly, but: IObject is in a separate assembly/namespace Base and A are in the same assembly/namespace each with correct using directives Implementation is in a third separate assembly namespace, also with correct using directives. Casting to A before trying to set MyObjectInterface doesn't work Specifically, I'm trying to set the value of MyObjectInterface to a mock object (though, I created a fake instead to no avail) I've tried everything I can think of. Please help before I lose more hair. edit I can't reproduce the error by creating a test app either, which is why I'm here and why I'm frustrated. @Reed Copsey: /* something */ is either an NUnit.DynamicMock(IMailer).MockInstance or a Fake object I created that inherits from IObject and just returns canned values. @Preet Sangha: I checked and no other assembly that is referenced has a definition for an IObject (specifically, it's called an IMailer). Thing is that intellisense picks up the Property, but when I compile, I get CS0117. I can even 'Go To Definition' in the implementation, and it takes me to where I defined it.

  • Why is Available Physical Memory (dwAvailPhys) > Available Virtual Memory (dwAvailVirtual) in call G

    - by Andrew
    I am playing with an MSDN sample to do memory stress testing (see: http://msdn.microsoft.com/en-us/magazine/cc163613.aspx) and an extension of that tool that specifically eats physical memory (see http://www.donationcoder.com/Forums/bb/index.php?topic=14895.0;prev_next=next). I am obviously confused though on the differences between Virtual and Physical Memory. I thought each process has 2 GB of virtual memory (although I also read 1.5 GB because of "overhead". My understanding was that some/all/none of this virtual memory could be physical memory, and the amount of physical memory used by a process could change over time (memory could be swapped out to disc, etc.)I further thought that, in general, when you allocate memory, the operating system could use physical memory or virtual memory. From this, I conclude that dwAvailVirtual should always be equal to or greater than dwAvailPhys in the call GlobalMemoryStatus. However, I often (always?) see the opposite. What am I missing. I apologize in advance if my question is not well formed. I'm still trying to get my head around the whole memory management system in Windows. Tutorials/Explanations/Book recs are most welcome!

  • What strategy do you use to sync your code when working from home

    - by Ben Daniel
    At my work I currently have my development environment inside a Virtual Machine. When I need to do work from home I copy my VM and any databases I need onto a laptop drive sized external USB drive. After about 10 minutes of copying I put the drive in my pocket and head home, copy back the VM and databases onto my personal computer and I'm ready to work. I follow the same steps to take the work back with me. So if I count the total amount of time I spend waiting around for files to finish copying in order for me to take work home and bring it back again, it comes to around 40 minutes! I do have a VPN connection to my work from home (providing the internet is up at both sites) and a decent internet speed (8mbits down/?up) but I find Remote Desktoping into my work machine laggy enough for me to want to work on my VM directly. So in looking at what other options I have or how I could improve my existing option I'm interested in what strategy you use or recommend to do work at home and keeping your code/environment in sync. EDIT: I'd prefer an option where I don't have to commit my changes into version control before I leave work - as I like to make meaningful descriptive comments in my commits, committing would take longer than just copying my VM onto a portable drive! lol Also I'd prefer a solution where my dev environment stays in sync too. Having said that I'm still very interested in your own solutions even if they don't exactly solve my problem as best as I'd like. :)

  • Why is WMDC/ActiveSync so flaky?

    - by Ira Rainey
    I'm developing a Windows Mobile app using the .NET Compact Framework 3.5 and VS2008, and for debugging using the Device Emulator V3, on Win7, and seem to have constant problems with Windows Mobile Device Centre (6.1) connecting. Using the Emulator Manager (9.0.21022.8) I cradle the device using DMA in WMDC. The problem is it's so flaky at actually connecting that it's becoming a pain. I find that when I turn my computer on, before I can get it to connect I have to open up WMDC, disable Connect over DMA, close WMDC down, reopen it again, and then it might cradle. Often I have to do this twice before it will cradle. Once it's cradled it's generally fine, but nothing seems consistent in getting it to connect. Connecting with physical devices is often better, although not always. If I plug a PDA into a USB socket other than the one it was originally plugged into then it won't connect at all. Often the best/most reliable connection method seems to be over Bluetooth, but that's quite slow. Anybody got any tips or advice?

  • Pentaho - Reporting Tool - Is the .prpt file (report template file) contains datasource information

    - by Yatendra Goel
    I am new Pentaho Reporting Tool. I have the following question: When I created a report using Pentaho Report Designer, it output a report file having .prpt extension. After that I found an example on internet where the following code were used to display the report in html format:| protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { ResourceManager manager = new ResourceManager(); manager.registerDefaults(); String reportPath = "file:" + this.getServletContext().getRealPath("sampleReport.prpt"); try { Resource res = manager.createDirectly(new URL(reportPath), MasterReport.class); MasterReport report = (MasterReport) res.getResource(); HtmlReportUtil.createStreamHTML(report, response.getOutputStream()); } catch (Exception e) { e.printStackTrace(); } } And the report got printed successfully. So as we haven't specified any datasource information here, I think that the .prpt file contains that information in it. If that's true than Isn't Jasper is better Reporting tool than Pentaho because when we display Jasper reports, we have to provide datasource details also so in that way our report is flexible and is not bound to any particular database.

  • Looking for Hardware that will easily interface with my .NET code.

    - by SkippyFire
    I'm a .NET C# developer looking to do some hardware interfacing/programming. I just want something super simple to mess around with. I have done one of those basic stamp projects, but I want something with less electrical work. A self-contained piece of hardware would be fine. I'm not really looking to do embedded programming... but that would actually be pretty cool if something was capable of running .net code. I'm looking for something that would be easy to connect, hopefully via USB. Serial ports seems to be more hit or miss nowadays with laptops and netbooks. Something I can easily send data to, like a mini LCD, or series of LED's. Better yet would be something that provides feedback, like a temperature sensor. The best would be something more featured that I could talk to. I would be able to send data to it, and it would send back responses. Maybe something like a servo that could report it's position? Or maybe something that I could set parameters on? Any ideas? Thanks in advance!

  • Algorithm to match list of regular expressions

    - by DSII
    I have two algorithmic questions for a project I am working on. I have thought about these, and have some suspicions, but I would love to hear the community's input as well. Suppose I have a string, and a list of N regular expressions (actually they are wildcard patterns representing a subset of full regex functionality). I want to know whether the string matches at least one of the regular expressions in the list. Is there a data structure that can allow me to match the string against the list of regular expressions in sublinear (presumably logarithmic) time? This is an extension of the previous problem. Suppose I have the same situation: a string and a list of N regular expressions, only now each of the regular expressions is paired with an offset within the string at which the match must begin (or, if you prefer, each of the regular expressions must match a substring of the given string beginning at the given offset). To give an example, suppose I had the string: This is a test string and the regex patterns and offsets: (a) his.* at offset 0 (b) his.* at offset 1 The algorithm should return true. Although regex (a) does not match the string beginning at offset 0, regex (b) does match the substring beginning at offset 1 ("his is a test string"). Is there a data structure that can allow me to solve this problem in sublinear time? One possibly useful piece of information is that often, many of the offsets in the list of regular expressions are the same (i.e. often we are matching the substring at offset X many times). This may be useful to leverage the solution to problem #1 above. Thank you very much in advance for any suggestions you may have!

  • TLS with SNI in Java clients

    - by ftrotter
    There is an ongoing discussion on the security and trust working group for NHIN Direct regarding the IP-to-domain mapping problem that is created with traditional SSL. If an HISP (as defined by NHIN Direct) wants to host thousands of NHIN Direct "Health Domains" for providers, then it will an "artificially inflated cost" to have to purchase an IP for each of those domains. Because Apache and OpenSSL have recently released TLS with support for the SNI extension, it is possible to use SNI as a solution to this problem on the server side. However, if we decide that we will allow server implementations of the NHINDirect transport layer to support TLS+SNI, then we must require that all clients support SNI too. OpenSSL based clients should do this by default and one could always us stunnel to implement an TLS+SNI aware client to proxy if your given programming language SSL implementation does not support SNI. It appears that native Java applications using OpenJDK do not yet support SNI, but I cannot get a straight answer out of that project. I know that there are OpenSSL Java libraries available but I have no idea if that would be considered viable. Can you give me a "state of the art" summary of where TLS+SNI support is for Java clients? I need a Java implementers perspective on this.

  • Keyboard hook return different symbols from card reader depends whther my app in focus or not

    - by user363868
    I code WinForm application where one of the input is magnetic stripe card reader (CR). I am using code George Mamaladze's article Processing Global Mouse and Keyboard Hooks in C# on codeproject.com to listen keyboard (USB card reader acts same way as keyboard) and I have weird situation. One card reader CR1 (Unitech MS240-2UG) produces keystroke which I intercept on KeyPress event analyze that I intercept certain patter like %ABCD-6EFJHI? and trigger some logic. Analysis required because user can type something else into application or in another application meanwhile my app is open When I use another card reader CR2 (IdTech IDBM-334133) keystroke intercepted by hook started from number 5 instead of % (It is actually same key on keyboard). Since it is starting sentinel it is very important for me to have ability recognize input from card reader. Moreover if my app running in background and I have focus on Notepad when I swipe card string %ABCD-6EFJHI? appears in Notepad and same way, with proper starting character) intercepted by keyboard hook. If swiped when focus on Form it is 5ABCD-6EFJHI? User who tried app with another card reader has same result as me with CR2. Only CR1 works for me as expected I was looking into Device manager of Windows and both devices use same HID driver supplied by MS. I checked devices though respective software from CR makers and starting and ending sentinels set to % and ? respective on both. I would appreciate and ideas and thoughts as I hit the wall myself Thank you

  • IValueConverter from string

    - by Aleksandar Toplek
    I have an Enum that needs to be shown in ComboBox. I have managed to get enum values to combobox using ItemsSource and I'm trying to localize them. I thought that that could be done using value converter but as my enum values are already strings compiler throws error that IValueConverter can't take string as input. I'm not aware of any other way to convert them to other string value. Is there some other way to do that (not the localization but conversion)? I'm using this marku extension to get enum values [MarkupExtensionReturnType(typeof (IEnumerable))] public class EnumValuesExtension : MarkupExtension { public EnumValuesExtension() {} public EnumValuesExtension(Type enumType) { this.EnumType = enumType; } [ConstructorArgument("enumType")] public Type EnumType { get; set; } public override object ProvideValue(IServiceProvider serviceProvider) { if (this.EnumType == null) throw new ArgumentException("The enum type is not set"); return Enum.GetValues(this.EnumType); } } and in Window.xaml <Converters:UserTypesToStringConverter x:Key="userTypeToStringConverter" /> .... <ComboBox ItemsSource="{Helpers:EnumValuesExtension Data:UserTypes}" Margin="2" Grid.Row="0" Grid.Column="1" SelectedIndex="0" TabIndex="1" IsTabStop="False"> <ComboBox.ItemTemplate> <DataTemplate DataType="{x:Type Data:UserTypes}"> <Label Content="{Binding Converter=userTypeToStringConverter}" /> </DataTemplate> </ComboBox.ItemTemplate> </ComboBox> And here is converter class, it's just a test class, no localization yet. public class UserTypesToStringConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { return (int) ((Data.UserTypes) value) == 0 ?

  • (C#) Get index of current foreach iteration

    - by Graphain
    Hi, Is there some rare language construct I haven't encountered (like the few I've learned recently, some on Stack Overflow) in C# to get a value representing the current iteration of a foreach loop? For instance, I currently do something like this depending on the circumstances: int i=0; foreach (Object o in collection) { ... i++; } Answers: @bryansh: I am setting the class of an element in a view page based on the position in the list. I guess I could add a method that gets the CSSClass for the Objects I am iterating through but that almost feels like a violation of the interface of that class. @Brad Wilson: I really like that - I've often thought about something like that when using the ternary operator but never really given it enough thought. As a bit of food for thought it would be nice if you could do something similar to somehow add (generically to all IEnumerable objects) a handle on the enumerator to increment the value that an extension method returns i.e. inject a method into the IEnumerable interface that returns an iterationindex. Of course this would be blatant hacks and witchcraft... Cool though... @crucible: Awesome I totally forgot to check the LINQ methods. Hmm appears to be a terrible library implementation though. I don't see why people are downvoting you though. You'd expect the method to either use some sort of HashTable of indices or even another SQL call, not an O(N) iteration... (@Jonathan Holland yes you are right, expecting SQL was wrong) @Joseph Daigle: The difficulty is that I assume the foreach casting/retrieval is optimised more than my own code would be. @Jonathan Holland: Ah, cheers for explaining how it works and ha at firing someone for using it.

  • MVC View Model Intellisense / Compile error

    - by Marty Trenouth
    I have one Library with my ORM and am working with a MVC Application. I have a problem where the pages won't compile because the Views can't see the Model's properties (which are inherited from lower level base classes). They system throws a compile error saying that 'object' does not contain a definition for 'ID' and no extension method 'ID' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?) implying that the View is not seeing the model. In the Controller I have full access to the Model and have check the Inherits from portion of the view to validate the correct type is being passed.

  • Why user control with code behind file doesn't want to compile under MVC2?

UserControl1.ascx looks like: <@ Control AutoEventWireup="true" Language="C#" CodeFile="~/Content/UserControl1.ascx.cs" Inherits="MVCDrill.Content.UserControl1" %> <div runat="server" id="mydiv"> <asp:LinkButton id="lb_text" runat="server"></asp:LinkButton> </div> UserControl1.ascx.cs looks like: using System; using System.Web; using System.Web.UI; namespace MVCDrill.Content { public class UserControl1 : UserControl { public string Text { get { return this.lb_text.Text; } set { this.lb_text.Text = value; } } } } I'm pretty sure this kind of stuff compiled under webforms but I'm getting compilation error: 'MVCDrill.Content.UserControl1' does not contain a definition for 'lb_text' and no extension method 'lb_text' accepting a first argument of type 'MVCDrill.Content.UserControl1' could be found (are you missing a using directive or an assembly reference?) Am I missing something? How to change it (what is the alternative) in MVC2 ? p.s. Intellisense sees lb_text with no problem. I've tried with different controls with the same outcome.

  • Detecting Xml namespace fast

    - by Anna Tjsoken
    Hello there, This may be a very trivial problem I'm trying to solve, but I'm sure there's a better way of doing it. So please go easy on me. I have a bunch of XSD files that are internal to our application, we have about 20-30 Xml files that implement datasets based off those XSDs. Some Xml files are small (<100Kb), others are about 3-4Mb with a few being over 10Mb. I need to find a way of working out what namespace these Xml files are in order to provide (something like) intellisense based off the XSD. The implementation of this is not an issue - another developer has written the code for this. But I'm not sure the best (and fastest!) way of detecting the namespace is without the use of XmlDocument (which does a full parse). I'm using C# 3.5 and the documents come through as a Stream (some are remote files). All the files are *.xml (I can detect if it was extension based) but unfortunately the Xml namespace is the only way. Right now I've tried XmlDocument but I've found it to be innefficient and slow as the larger documents are awaiting to be parsed (even the 100Kb docs). public string GetNamespaceForDocument(Stream document); Something like the above is my method signature - overloads include string for "content". Would a RegEx (compiled) pattern be good? How does Visual Studio manage this so efficiently? Another college has told me to find a fast Xml parser in C/C++, parse the content and have a stub that gives back the namespace as its slower in .NET, is this a good idea?

  • Zend file upload error

    - by jgnasser
    I am attempting to upload a file using Zend Framework 1.8 and I get some errors. Here is the code snippet: The form element: $element = new Zend_Form_Element_File('doc'); $element->setLabel('Upload an image:') ->setDestination('/path/to/my/upload/folder'); $element->addValidator('Count', false, 1); $element->addValidator('Size', false, 102400); $element->addValidator('Extension', false, 'jpg,png,gif,doc,docx,xls,xlsx,txt'); $this->addElement($element); The code for handling the upload: $adapter = new Zend_File_Transfer_Adapter_Http(); if (!$adapter->receive()) { $messages = $adapter->getMessages(); echo implode("\n", $messages); } This works fine and the file is uploaded but I get the error "The file 'doc' was illegal uploaded, possible attack". I managed to get past this problem by not creating a new Zend_File_Transfer_Adapter_Http() but instead using: $adapter = $form->doc->getTransferAdapter(); With this modification, the first error disappears but now I have an error saying I have provided 2 files instead of one (probably its reading the temp) and when I adjust the validator to accept two files I then get the arror saying "The file 'doc' was not found" and the upload now fails completely. Please help

  • MSBuild "Wrapper" fails while VS2010 "Pure" compile succeeds for MFC application in CruiseControl.NE

    - by ee
    The Overview I am working on a Continuous Integration build of a MFC appliction via CruiseControl.net and VS2010. When building my .sln, a "Visual Studio" CCNet task (devenv) works, but a wrapper MSBuild script run via the CCNet MSBuild task fails with errors like: error RC1015: cannot open include file 'winres.h'.. error C1083: Cannot open include file: 'afxwin.h': No such file or directory error C1083: Cannot open include file: 'afx.h': No such file or directory The Question How can I adjust the build environment of my msbuild wrapper so that the application builds correctly? (Pretty clearly the MFC paths aren't right for the msbuild environment, but how do i fix it for MSBuild+VS2010+MFC+CCNet?) Background Details We have successfully upgraded an MFC application (.exe with some MFC extension .dlls) to Visual Studio 2010 and can compile the application without issue on developer machines. Now I am working on compiling the application on the CI server environment I did a full installation of VS2010 (Professional) on the build server. In this way, I knew everything I needed would be on the machine (one way or another) and that this would be consistent with developer machines. VS2010 is correctly installed on the CI server, and the devenv task works as expected I now have a wrapper MSBuild script that does some extended version processing and then builds the .sln for the application via an MSBuild task. This wrapper script is run via CCNet's MSBuild task and fails with the above mentioned errors My Assumptions This seems to be a missing/wrong configuration of include paths to standard header resources of the MFC persuasion I should be able to coerce the MSBuild environment to consider the relevant resource files from my VS2010 install and have this approach work. But how do I do that? Am I setting Environment variables? Registry settings? I can see how one can inject additional directories in some cases, but this seems to need a more systemic configuration at the compiler defaults level.
