  • csc.exe not found error

    - by pokrate
    I have installed a fresh copy of windows xp 2002 with SP2, and then VS.net 2008 enterprise edition. I am trying to build a simplest possible web application, and its not compiling giving error csc.exe not found. I googled a lot, and spot the problem in the following section in web.config : <system.codedom> <compilers> <compiler language="c#;cs;csharp" extension=".cs" warningLevel="4" type="Microsoft.CSharp.CSharpCodeProvider, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <providerOption name="CompilerVersion" value="v3.5"/> <providerOption name="WarnAsError" value="false"/> </compiler> <compiler language="vb;vbs;visualbasic;vbscript" extension=".vb" warningLevel="4" type="Microsoft.VisualBasic.VBCodeProvider, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <providerOption name="CompilerVersion" value="v3.5"/> <providerOption name="OptionInfer" value="true"/> <providerOption name="WarnAsError" value="false"/> </compiler> </compilers> </system.codedom> But if i remove the csharp compiler section , and then compile, it compiles fine with vb compiler section. And if I change the value from v3.5 to v2.0 in the of csharp section, then also it compiles fine. But then all my Linq Queries are not recognized by the compiler. But System.Linq and all classes present in it are accessible in the code. Please help in this weird behavior.

  • Why are mercurial subrepos behaving as unversioned files in eclipse AND torotoiseHG

    - by noam
    I am trying to use the subrepo feature of mercurial, using the mercurial eclipse plugin\tortoiseHG. These are the steps I took: Created an empty dir /root cloned all repos that I want to be subrepos inside this folder (/root/sub1, /root/sub2) Created and added the .hgsub file in the root repo /root/.hgsub and put all the mappings of the sub repos in it using tortoiseHG, right clicked on /root and selected create repository here again with tortoise, selected all the files inside /root and added them to to the root repo commited the root repo pushed the local root repo into an empty repo I have set up on kiln Then, I pulled the root repo in eclipse, using import-mercurial. Now I see that all the subrepos appear as though they are unversioned (no "orange cylinder" icon next to their corresponding folders in the eclipse file explorer). Furthermore, when I right click on one of the subrepos, I don't get all the hg commands in the "team" menu as I usually get, with root projects - no "pull", "push" etc. Also, when I made a change to a file in a subrepo, and then "committed" the root project, it told me there were no changes found. I see the same behavior also in tortoiseHG - When I am browsing files under /root, the files belonging directly to the root repo have an small icon (a V sign) on them marking they are version controlled, while the subrepos' folders aren't marked as such. Am I doing something wrong, or is it a bug?

  • Why Spark viewengine renders unnecessary (or unexpected) quotes?

    - by Arnis L.
    If i add pageBaseType="Spark.Web.Mvc.SparkView" in my web.config (necessary to fix intellisense), somehow it does not render links (probably not only) correctly anymore. This is how it's supposed to look like (and does, if page base type is not specified)= This is how it looks when base type is specified= Chrome source viewer shows identical page source code for both cases= <body> <div class="content"> <div class="navigation"> <a href="/Employee/List">Employees</a> <a href="/Product/List">Products</a> <a href="/Store/List">Stores</a> <div class="navigation_title"> Navigation</div> </div> <div class="main"> <div class="content"> <h2>Employees</h2>Nothing found... &lt;a href=&quot;/Employee/Create&quot;&gt;Create&lt;/a&gt; </div> </div> </div> </body> Developer tools does not= So - why my link gets htmlencoded (if that's what happens)? If it's default behavior, then how to render raw html? Using latest Spark version, rebuilt with Asp.Net Mvc2 RC assemblies.

  • Why do I get "Error 6060" when I try to use DBD::Advantage with a 64-bit perl on Linux?

    - by WarheadsSE
    I realize that I am attempting to go beyond the "supported" behavior of the manf's released drivers for Perl, after all they have only released it in package with x86 .so's. However, since I cannot use their package with x64 Perl on a RHEL 5.4 x86_64 box, and maintaining a seperate install of x86 Perl just for this one package, I have made an attempt to get this puppy working thanks to released 64-bit .so's that accompany other driver packages for Advantage. What I have done to this point: download beta 10 DBI drivers, in 32 download beta 10 PHP extension (it contains 32 and x86_64) copy the required DLLs into the ads-lib location (eg /usr/local/ads/lib64) compile the Perl DBI driver with the path to the lib64's .so's Good compilation, good install, good use. The problem is that I always get : failed: [iAnywhere Solutions][Advantage SQL][ASA] Error 6060: Advantage Database Server not available on specified server. axServerConnect (SQL-HY000)(DBD: db_login/SQLConnect err=-1) Does anyone have any ideas? EDIT: fixed package name in post title EDIT: Updated title. It appears that it's not just the x64 perl, but the RHEL 5.4 underneath that may be interfering. As commented below, I managed to shoe-horn a x86 perl onto the system, and compile the DBD::Advantage 9.99, and later replacing that with 9.10, and none of these x86 would connect either. Neither library (9.99 or 9.10) in either bit-edness will connect from this x86_64 server to the windows server's UNC path. I have successfully mounted this share without problems, but still I cannot seem to connect to the 9.1. I have tried: \hostname\PATH \FQDN\PATH \IP\PATH and all of these variations with the port (default) 6262 included. My windows machine connects fine, with both 9.1 and 9.99 from strawberry perl.

  • Virtual properties duplicated during serialization when XmlElement attribute used

    - by Laramie
    The Goal: XML serialize an object that contains a list of objects of that and its derived types. The resulting XML should not use the xsi:type attribute to describe the type, to wit the names of the serialized XML elements would be an assigned name specific to the derived type, not always that of the base class, which is the default behavior. The Attempt: After exploring IXmlSerializable and IXmlSerializable with eerie XmlSchemaProvider methods and voodoo reflection to return specialized schemas and an XmlQualifiedName over the course of days, I found I was able to use the simple [XmlElement] attribute to accomplish the goal... almost. The Problem: Overridden properties appear twice when serializing. The exception reads "The XML element 'overriddenProperty' from namespace '' is already present in the current scope. Use XML attributes to specify another XML name or namespace for the element." I attempted using a *Specified property (see code), but it didn't work. Sample Code: Class Declaration using System; using System.Collections.Generic; using System.Xml.Serialization; [XmlInclude(typeof(DerivedClass))] public class BaseClass { public BaseClass() { } [XmlAttribute("virt")] public virtual string Virtual { get; set; } [XmlIgnore] public bool VirtualSpecified { get { return (this is BaseClass); } set { } } [XmlElement(ElementName = "B", Type = typeof(BaseClass), IsNullable = false)] [XmlElement(ElementName = "D", Type = typeof(DerivedClass), IsNullable = false)] public List<BaseClass> Children { get; set; } } public class DerivedClass : BaseClass { public DerivedClass() { } [XmlAttribute("virt")] public override string Virtual { get { return "always return spackle"; } set { } } } Driver: BaseClass baseClass = new BaseClass() { Children = new List<BaseClass>() }; BaseClass baseClass2 = new BaseClass(){}; DerivedClass derivedClass1 = new DerivedClass() { Children = new List<BaseClass>() }; DerivedClass derivedClass2 = new DerivedClass() { Children = new List<BaseClass>() }; baseClass.Children.Add(derivedClass1); baseClass.Children.Add(derivedClass2); derivedClass1.Children.Add(baseClass2); I've been wrestling with this on and off for weeks and can't find the answer anywhere.

  • 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.

  • Django stupid mark_safe?

    - by Mark
    I wrote this little function for writing out HTML tags: def html_tag(tag, content=None, close=True, attrs={}): lst = ['<',tag] for key, val in attrs.iteritems(): lst.append(' %s="%s"' % (key, escape_html(val))) if close: if content is None: lst.append(' />') else: lst.extend(['>', content, '</', tag, '>']) else: lst.append('>') return mark_safe(''.join(lst)) Which worked great, but then I read this article on efficient string concatenation (I know it doesn't really matter for this, but I wanted consistency) and decided to update my script: def html_tag(tag, body=None, close=True, attrs={}): s = StringIO() s.write('<%s'%tag) for key, val in attrs.iteritems(): s.write(' %s="%s"' % (key, escape_html(val))) if close: if body is None: s.write(' />') else: s.write('>%s</%s>' % (body, tag)) else: s.write('>') return mark_safe(s.getvalue()) But now my HTML get escaped when I try to render it from my template. Everything else is exactly the same. It works properly if I replace the last line with return mark_safe(unicode(s.getvalue())). I checked the return type of s.getvalue(). It should be a str, just like the first function, so why is this failing?? Also fails with SafeString(s.getvalue()) but succeeds with SafeUnicode(s.getvalue()). I'd also like to point out that I used return mark_safe(s.getvalue()) in a different function with no odd behavior.

  • Layering Cocoa WebView - Drawing on top?

    - by Josh
    http://stackoverflow.com/questions/1618498/webview-in-core-animation-layer The only other thread I can find is the above which doesn't necessarily fit my needs. Is there a reliable way to simply draw a view on top of a webview? I've tried to layer a regular NSView on top of WebView, and it draws right at first, but any movement in the webview (scrolling the page etc) appears to invalidate the view and produces visual artifacts. I've tried: [[[NSApp mainWindow] contentView] addSubview:view positioned:NSWindowAbove relativeTo:webView]; No luck there, same problems -- z-ordering doesn't seem to work unless I'm missing something. Is this just a limitation of webviews? I also tried implementing the view above as a window, which worked much better (just controlled the location of the window programmatically). However, the desired behavior is for the user to enter some text into this window, but for it not to steal "focus" -- ie the main window goes inactive (the x - + go gray) when the user clicks on the text field in the new window. Any way to avoid that? I've tried subclassing NSWindow and overriding canBecomeKey (return YES) and canBecomeMain (return NO) but the window still steals focus. Josh

  • How to nest shapes in a DSL Tools diagram?

    - by Paul Lalonde
    I have a DSL containing two main domain classes: Area and Entity. Areas are represented visually by a GeometryShape, whereas entities are represented by a CompartmentShape. Entities can be embedded in an Area, or not (in this case they are embedded in the root object, which is a kind of Area). There may be relationships between entities, including between entities in different areas. Areas cannot be embedded inside of other areas, nor entities embedded inside of other entities. My problem is that I cannot get the behavior I want from the diagram. The embedding of entities in areas works perfectly well at the model level, but the visual representation behaves erratically. For example, if I drag an entity that was created in an area outside of that area, it no longer responds to mouse clicks (I have code that performs the re-parenting, but somehow the diagram side of things is broken). I have searched high and low for samples of how to do this, and come up empty. Every example I've found on the web simulates nesting via "references" relationships, whereas I am performing true embedding of the domain classes (and therefore of their associated shape classes). Does anyone have an example of how to do this? While I'm venting, am I the only one who thinks the diagram/shape classes are massively under-documented?

  • System.Windows.Forms.DataVisualization Namespace Fine in One Class but Not in Another

    - by jxpx777
    Hi. I'm getting this error The type or namespace name 'DataVisualization' does not exist in the namespace 'System.Windows.Forms' (are you missing an assembly reference?) Here is my using section of the class: using System; using System.Collections; using System.Collections.Generic; using System.Windows.Forms.DataVisualization.Charting; using System.Windows.Forms.DataVisualization.Charting.Borders3D; using System.Windows.Forms.DataVisualization.Charting.ChartTypes; using System.Windows.Forms.DataVisualization.Charting.Data; using System.Windows.Forms.DataVisualization.Charting.Formulas; using System.Windows.Forms.DataVisualization.Charting.Utilities; namespace myNamespace { public class myClass { // Usual class stuff } } The thing is that I am using the same DataVisualization includes in another class. The only thing that I can think that is different is that the classes that are giving this missing namespace error are Solution Items rather than specific to a project. The projects reference them by link. Anyone have thoughts on what the problem is? I've installed the chart component, .Net 3.5 SP1, and the Chart Add-in for Visual Studio 2008. UPDATE: I moved the items from Solution Items to be regular members of my project and I'm still seeing the same behavior. UPDATE 2: Removing the items from the Solution Items and placing them under my project worked. Another project was still referencing the files which is why I didn't think it worked previously. I'm still curious, though, why I couldn't use the namespace when the classes were Solution Items but moving them underneath a project (with no modifications, mind you) instantly made them recognizable. :\

  • Configure Windows firewall to prevent an application from listening on a specific port [closed]

    - by U-D13
    The issue: there are many applications struggling to listen on port 80 (Skype, Teamviewer et al.), and to many of them that even is not essential (in the sense that you can have a httpd running and blocking the http port, and the other application won't even squeak about being unable to open the port). What makes things worse, some of the apps are... Well, I suppose, that it's okay that the mentally impaired are being integrated in the society by giving them a job to do, but... Programming requires some intellectual effort, in my humble opinion... What I mean is that there is no way to configure the app not to use specific ports (that's what you get for using proprietary software) - you can either add it to windows firewall exceptions (and succumb to undesired port opening behavior) or not (and risk losing most - if not all - of the functionality). Technically, it is not impossible for the firewall to deny an application opening an incoming port even if the application is in the exception list. And if this functionality is built into the Windows firewall somewhere, there should be a way to activate it. So, what I want to know is: whether there exists such an option, and if it does how to activate it.

  • Binding event handlers to specific elements, using bubbling (JavaScript/jQuery)

    - by Bungle
    I'm working on a project that approximates the functionality of Firebug's inspector tool. That is, when mousing over elements on the page, I'd like to highlight them (by changing their background color), and when they're clicked, I'd like to execute a function that builds a CSS selector that can be used to identify them. However, I've been running into problems related to event bubbling, and have thoroughly confused myself. Rather than walk you down that path, it might make sense just to explain what I'm trying to do and ask for some help getting started. Here are some specs: I'm only interested in elements that contain a text node (or any descendant elements with text nodes). When the mouse enters such an element, change its background color. When the mouse leaves that element, change its background color back to what it was originally. When an element is clicked, execute a function that builds a CSS selector for that element. I don't want a mouseover on an element's margin area to count as a mouseover for that element, but for the element beneath (I think that's default browser behavior anyway?). I can handle the code that highlights/unhighlights, and builds the CSS selector. What I'm primarily having trouble with is efficiently binding event handlers to the elements that I want to be highlightable/clickable, and avoiding/stopping bubbling so that mousing over a (<p>) element doesn't also execute the handler function on the <body>, for example. I think the right way to do this is to bind event handlers to the document element, then somehow use bubbling to only execute the bound function on the topmost element, but I don't have any idea what that code looks like, and that's really where I could use help. I'm using jQuery, and would like to rely on that as much as possible. Thanks in advance for any guidance!

  • Accessing an excel file throws OleDbException but keeps handle on file

    - by Jonn
    Really odd that I'd get an oledbexception but turns out that the file's handle is still with the original file. I've been searching through google and keep finding the same problem but no solutions. Connection String: "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + filePath + ";" + "Extended Properties=Excel 8.0;"; Note that it works on every other file except a particular excel file. Exception: System.Data.OleDb.OleDbException: No error information available: E_UNEXPECTED(0x8000FFFF). And then I have exception handling like this: try { IEnumerable<string> worksheetNames = GetWorkbookWorksheetNames(connString); DataSet ds; foreach (string worksheetName in worksheetNames) { OleDbDataAdapter dataAdapter = new OleDbDataAdapter("SELECT * FROM [" + worksheetName + "]", connString); ds = new DataSet(); dataAdapter.Fill(ds, "ExcelInfo"); DataTable dt = ds.Tables["ExcelInfo"]; entityList.AddRange(GetDataFromDataTable(dt, worksheetName)); } } catch (OleDbException ex) { File.Move(filePath, filePath + ".invalidFormat.xls"); } Has anyone else encountered this behavior? And I'm not sure how to handle an error that keeps the handle on the file I'm supposed to process. It sort of freezes everything in place.

  • IE problem: keyboard interaction with checkbox

    - by Bobby Eickhoff
    I have an HTML table, and each row has a checkbox for selecting or deselecting its row. Whenever a checkbox changes value, I need to add or remove highlighting to the row and also ensure that the page's submit button is only enabled when at least one row is selected and disabled otherwise. The checkbox event handler is defined by the following function: function getCheckboxCallback() { return function () { var parentRow = getParentRow(this); if (!parentRow) { return; // No parent row found; abort } // Adjust the appearance of the row setSelected(parentRow, this.checked); // Count the number of selected table rows, and disable the submit // button whenever no rows are selected enforceInvariants(); return true; }; } Elsewhere in the same module, the checkboxes are given the event handlers: checkbox.onchange = getCheckboxCallback(); checkbox.onclick = getCheckboxCallback(); // alleged IE fix I'm working in Windows XP, and everything works fine in both Firefox 3 and Opera 9. However, IE 7 does not handle keyboard interaction well (mouse interaction works fine). The problem is that if a checkbox has the focus and I hit the spacebar, the checkbox doesn't get checked -- instead it gets half checked (it has the same shadowed appearance that it would get immediately after a mousedown). I have to press the spacebar a second time to actually check the box. Similarly, it requires two key presses to uncheck it. Oddly enough, if I hold down the spacebar for a few moments, then a single press works as expected. Can anyone explain what is going on here? Is there something I'm doing wrong in the JavaScript code that is causing this behavior? How can I fix this?

  • cannot override a concrete member without a third member that's overridden by both

    - by huynhjl
    What does the following error message mean? cannot override a concrete member without a third member that's overridden by both (this rule is designed to prevent ``accidental overrides''); I was trying to do stackable trait modifications. It's a little bit after the fact since I already have a hierarchy in place and I'm trying to modify the behavior without having to rewrite a lot of code. I have a base class called AbstractProcessor that defines an abstract method sort of like this: class AbstractProcessor { def onPush(i:Info): Unit } I have a couple existing traits, to implement different onPush behaviors. trait Pass1 { def onPush(i:Info): Unit = { ... } } trait Pass2 { def onPush(i:Info): Unit = { ... } } So that allows me to use new AbstractProcessor with Pass1 or new AbstractProcessor with Pass2. Now I would like to do some processing before and after the onPush call in Pass1 and Pass2 while minimizing code changes to AbstractProcessor and Pass1 and Pass2. I thought of creating a trait that does something like this: trait Custom extends AbstractProcessor { abstract override def onPush(i:Info): Unit = { // do stuff before super.onPush(i) // do stuff after } And using it with new AbstractProcessor with Pass1 with Custom and I got that error message.

  • Absolute positioning in IE6, using left: 0; and right: 0; simultaneously

    - by Zane
    Here is my website: http://dagwaging.110mb.com/ View it in any good browser, then in IE6. It dies in IE6. It seems that in IE6, one can't do this: div { position: absolute; left: 0px; right: 0px; } or this: div { position: absolute; top: 0px; bottom: 0px; } Absolute positions cannot be set for left and right or top and bottom at the same time. This is terrible, because that is pretty much the basis of my site design. The HTML can be viewed on the site, and the CSS is in /style.css. I'd like to fix this without invalidating my CSS or HTML. Can this be done? Another problem is that my content uses min-width and max-width to avoid over-stretching or compressing the content within. IE6 can't do min-width, so how can I replicate this behavior?

  • Log off from Remote Desktop Session does not closing Session, showing the login screen again on Wind

    - by Santhosha
    Hi As per requirement we have written one custom GINA. I have observed one interesting behavior in Windows XP 32 Bit(SP2). Customized GINA internally calls windows default Windows GINA(msgina.dll) and shows one extra window as per our requirement. I used to do remote desktop to XP machine from my machine. After replacing Windows GINA with customized GINA I tried to log off from the XP Machine(I am Using Remote Desktop Connection to log in), Log off completes successfully(After showing saving your settings, Closing network connections etc) and I will get log in screen which we get during log on, this is not expected comapred to other flavors of Windows OD. Where as in other operating systems such as Windows XP 64 Bit/ Windows 2003 32/64 Bit even after replacing the Windows Gina with custom GINA remote desktop session closes after log off from the machine. I have tried installing Novell GINA on Windows XP 32 Bit but i have not find any issue with that. I have Tried upgrading XP SP2 to SP3, still i am facing the same issue. Whether anyone faced Such issues when worked with Windows GINA? Thanks in advance Santhosha K S

  • Use the output of logs in the execution of a program

    - by myle
    When I try to create a specific object, the program crashes. However, I use a module (mechanize) which logs useful information just before the crash. If I had somehow this information available I could avoid it. Is there any way to use the information which is logged (when I use the function set_debug_redirects) during the normal execution of the program? Just to be a bit more specific, I try to emulate the login behavior in a webpage. The program crashes because it can't handle a specific Following HTTP-EQUIV=REFRESH to <omitted_url>. Given this url, which is available in the logs but not as part of the exception which is thrown, I could visit this page and complete successfully the login process. Any other suggestions that may solve the problem are welcomed. It follows the code so far. SERVICE_LOGIN_BOX_URL = "https://www.google.com/accounts/ServiceLoginBox?service=adsense&ltmpl=login&ifr=true&rm=hide&fpui=3&nui=15&alwf=true&passive=true&continue=https%3A%2F%2Fwww.google.com%2Fadsense%2Flogin-box-gaiaauth&followup=https%3A%2F%2Fwww.google.com%2Fadsense%2Flogin-box-gaiaauth&hl=en_US" def init_browser(): # Browser br = mechanize.Browser() # Cookie Jar cj = cookielib.LWPCookieJar() br.set_cookiejar(cj) # Browser options br.set_handle_equiv(True) br.set_handle_gzip(False) br.set_handle_redirect(True) br.set_handle_referer(True) br.set_handle_robots(True) br.set_handle_refresh(mechanize._http.HTTPRefreshProcessor(), max_time=30.0, honor_time=False) # Want debugging messages? #br.set_debug_http(True) br.set_debug_redirects(True) #br.set_debug_responses(True) return br def adsense_login(login, password): br = init_browser() r = br.open(SERVICE_LOGIN_BOX_URL) html = r.read() # Select the first (index zero) form br.select_form(nr=0) br.form['Email'] = login br.form['Passwd'] = password br.submit() req = br.click_link(text='click here to continue') try: # this is where it crashes br.open(req) except HTTPError, e: sys.exit("post failed: %d: %s" % (e.code, e.msg)) return br

  • Cross-platform and language (de)serialization

    - by fwgx
    I'm looking for a way to serialize a bunch of C++ structs in the most convenient way so that the serialization is portable across C++ and Java (at a minimum) and across 32bit/64bit, big/little endian platforms. The structures to be serialized just contain data, i.e. they're pure data objects with no state or behavior. The idea being that we serialize the structs into an octet blob that we can store in a database "generically" and be read out later on. Thus avoiding changing the database whenever a struct changes and also avoiding assigning each data member to a field - i.e. we only want one table to hold everything "generically" as a binary blob. This should make less work for developers and require less changes when structures change. I've looked at boost.serialize but don't think there's a way to enable compatibility with Java. And likewise for inheriting Serializable in Java. If there is a way to do it by starting with an IDL file that would be best as we already have IDL files that describe the structures. Cheers in advance!

  • Represent multiple Null/Generic objects in an ActiveRecord association?

    - by slothbear
    I have a Casefile model that belongs_to a Doctor. In additional to all the "real" doctors, there are several generic Doctors: "self-treated", "not specified", and "removed" (it used to have a real doctor, but no longer does). I suspect there will be even more generic values in the future. I started with special "doctors" in the database, generated from seed. The generic Doctors only need to respond to the "name" and "real_doctor?" methods. This worked with one, was strained with two, and now feels completely broken. I want to change the behavior and can't figure out how to test it, a bad sign. Creating all the generic objects for testing is also trouble, including fake values to pass validation of the required Doctor attributes. The Null Object pattern works well for one generic object. The "name" method could check casefile.doctor.nil? and return "self-treated", as demonstrated by Craig Ambrose. What pattern should I use when there are multiple generic objects with very limited state?

  • How can I create a WebBrowser control (ActiveX / IWebBrowser2) without a UI?

    - by wangminhere
    I cannot figure out how to use the WebBrowser control without having it create a window in the taskbar. I am using the IWebBrowser2 ActiveX control directly because I need to use some of the advanced features like blocking downloading JAVA/ActiveX/images etc. That apparently is not available in the WPF or winforms WebBrowser wrappers (but these wrappers do have the ability to create the control with no UI) Here is my code for creating the control: Type webbrowsertype = Type.GetTypeFromCLSID(Iid_Clsids.CLSID_WebBrowser, true); m_WBWebBrowser2 = (IWebBrowser2)System.Activator.CreateInstance(webbrowsertype); m_WBWebBrowser2.Visible = false; m_WBOleObject = (IOleObject)m_WBWebBrowser2; int iret = m_WBOleObject.SetClientSite(this); iret = m_WBOleObject.SetHostNames("me", string.Empty); tagRECT rect = new tagRECT(0, 0, 0, 0); tagMSG nullMsg = new tagMSG(); m_WBOleInPlaceObject = (IOleInPlaceObject)m_WBWebBrowser2; //INPLACEACTIVATE the WB iret = m_WBOleObject.DoVerb((int)OLEDOVERB.OLEIVERB_INPLACEACTIVATE, ref nullMsg, this, 0, IntPtr.Zero, ref rect); IConnectionPointContainer cpCont = (IConnectionPointContainer)m_WBWebBrowser2; Guid guid = typeof(DWebBrowserEvents2).GUID; IConnectionPoint m_WBConnectionPoint = null; cpCont.FindConnectionPoint(ref guid, out m_WBConnectionPoint); m_WBConnectionPoint.Advise(this, out m_dwCookie); This code works perfectly but it shows a window in the taskbar. If i omit the DoVerb(OLEDOVERB.OLEIVERB_INPLACEACTIVATE) call, then Navigating to a webpage is not working properly. Navigate() will not download everything on the page and it never fires the DocumentComplete event. If I add a DoVerb(OLEIVERB_HIDE) then I get the same behavior as if I omitted the DoVerb(OLEDOVERB.OLEIVERB_INPLACEACTIVATE) call. This seems like a pretty basic question but I couldn't find any examples anywhere.

  • C# COM Cross Thread problem

    - by user364676
    Hi, we're developing a software to control a scientific measuring device. it provides a COM-Interface defines serveral functions to set measurement parameters and fires an event when it measured data. in order to test our software, i'm implementing a simulation of that device. the com-object runs a loop which periodically fires the event. another loop in the client app should now setup up the com-simulator using the given functions. i created a class for measuring parameters which will be instanciated when setting up a new measurement. // COM-Object public class MeasurementParams { public double Param1; public double Param2; } public class COM_Sim : ICOMDevice { public MeasurementParams newMeasurement; IClient client; public int NewMeasurement() { newMeasurment = new MeasurementParam(); } public int SetParam1(double val) { // why is newMeasurement null when method is called from client loop newMeasurement.Param1 = val; } void loop() { while(true) { // fire event client.HandleEvent; } } } public class Client : IClient { ICOMDevice server; public int HandleEvent() { // handle this event server.NewMeasurement(); server.SetParam1(0.0); } void loop() { while(true) { // do some stuff... server.NewMeasurement(); server.SetParam1(0.0); } } } both of the loops run in independent threads. when server.NewMeasurement() is called, the object on the server is set to a new instance. but in the next function, the object is null again. do the same when handling the server-event, it works perfectly, because the method runs in the servers thread. how to make it work from client-thread as well. as the client is meant to be working with the real device, i cannot modify the interfaces given by the manufactor. also i need to setup measurements independent from the event-handler, which will be fired not regulary. i assume this problem related to multithreaded-COM behavior but i found nothing on this topic.

  • Why does the same Getopt::Long code work differently in different programs?

    - by ennuikiller
    The following code works in one script yet in another only works if a specify the -- end of options flag before specifying an option: my $opt; GetOptions( 'help|h' => sub { usage("you want help?? hahaha, hopefully you're not serious!!"); }, 'file|f=s' => \$opt->{FILE}, 'report|r' => \$opt->{REPORT}, ) or usage("Bad Options"); In other words, the same code words in good.pl and bad.pl like so: good.pl -f bad.pl -- -f If I try bad.pl -f I get unknown option:f. Anyone have any clue as to what can cause this behavior? Thanks in advance! I've solved this..... and btw it's a VERY clear question (so why the downvotes)? I'll state it again: What would cause the identical GetOptions block to work in these 2 ways: "good.pl -f" "bad.pl -- -f" see how clear? Maybe you guys should think about it as if it were a TEST!

  • Microsoft Solver Foundation constraint

    - by emaster70
    Hello, I'm trying to use Microsoft Solver Foundation 2 to solve a fairly complicated situation, however I'm stuck with an UnsupportedModelException even when I dumb down the model as much as possible. Does anyone have an idea of what I'm doing wrong? Following is the least example required to reproduce the problematic behavior. var ctx = SolverContext.GetContext(); var model = ctx.CreateModel(); var someConstant = 1337.0; var decisionA = new Decision(Domain.Real, "decisionA"); var decisionB = new Decision(Domain.Real, "decisionB"); var decisionC = new Decision(Domain.Real, "decisionC"); model.AddConstraint("ca", decisionA <= someConstant); model.AddConstraint("cb", decisionB <= someConstant); model.AddConstraint("cc", decisionC <= someConstant); model.AddConstraint("mainConstraint", Model.Equal(Model.Sum(decisionA, decisionB, decisionC), someConstant)) model.AddGoal("myComplicatedGoal", GoalKind.Minimize, decisionC); var solution = ctx.Solve(); solution.GetReport().WriteTo(Console.Out); Console.ReadKey(); Please consider that my actual model should include, once complete, a few constraints in the form of a*a+b*a <= someValue, so if what I'm willing to do ultimately isn't supported, please let me know in advance. If that's the case I'd also appreciate a suggestion of some other solver with a .NET friendly interface that I could use (only well-known commercial packages, please). Thanks in advance
