  • Call a dynamically generated method on a ILGenerator on the same type

    - by Thiado de Arruda
    Normally, when I want to call a dynamic method in another ILGenerator object that is writing a method on the same type I do the following : generator.Emit(OpCodes.Ldarg_0); // reference to the current object generator.Emit(OpCodes.Ldstr, "someArgument"); generator.Emit(OpCodes.Call, methodBuilder); //this methodbuilder is also defined on this dynamic type. However, I faced the following problem: I cant have a reference to the methodbuilder of the method I want to call, because it is generated by another framework(I only get a reference to the current TypeBuilder). This method is defined as protected virtual(and overriden on the methodbuilder I cant get a reference to) in the base class of the current dynamic type and I can get a reference to it by doing this : generator.Emit(OpCodes.Ldarg_0); // reference to the current object generator.Emit(OpCodes.Ldstr, "someArgument"); generator.Emit(OpCodes.Call, baseType.GetMethod("SomeMethodDefinedInBaseClassThatWasOverridenInThisDynamicType")); The problem is that this calls the method on the base type and not the overriden method. Is there any way I can get a reference to a methodbuilder only having a reference to the typebuilder that defined it? Or is there a way to call a method using ILGenerator without having to pass the 'MethodInfo' object to it?

  • Supporting multiple instances of a plugin DLL with global data

    - by Bruno De Fraine
    Context: I converted a legacy standalone engine into a plugin component for a composition tool. Technically, this means that I compiled the engine code base to a C DLL which I invoke from a .NET wrapper using P/Invoke; the wrapper implements an interface defined by the composition tool. This works quite well, but now I receive the request to load multiple instances of the engine, for different projects. Since the engine keeps the project data in a set of global variables, and since the DLL with the engine code base is loaded only once, loading multiple projects means that the project data is overwritten. I can see a number of solutions, but they all have some disadvantages: You can create multiple DLLs with the same code, which are seen as different DLLs by Windows, so their code is not shared. Probably this already works if you have multiple copies of the engine DLL with different names. However, the engine is invoked from the wrapper using DllImport attributes and I think the name of the engine DLL needs to be known when compiling the wrapper. Obviously, if I have to compile different versions of the wrapper for each project, this is quite cumbersome. The engine could run as a separate process. This means that the wrapper would launch a separate process for the engine when it loads a project, and it would use some form of IPC to communicate with this process. While this is a relatively clean solution, it requires some effort to get working, I don't now which IPC technology would be best to set-up this kind of construction. There may also be a significant overhead of the communication: the engine needs to frequently exchange arrays of floating-point numbers. The engine could be adapted to support multiple projects. This means that the global variables should be put into a project structure, and every reference to the globals should be converted to a corresponding reference that is relative to a particular project. There are about 20-30 global variables, but as you can imagine, these global variables are referenced from all over the code base, so this conversion would need to be done in some automatic manner. A related problem is that you should be able to reference the "current" project structure in all places, but passing this along as an extra argument in each and every function signature is also cumbersome. Does there exist a technique (in C) to consider the current call stack and find the nearest enclosing instance of a relevant data value there? Can the stackoverflow community give some advice on these (or other) solutions?

  • subquery in join with doctrine dql

    - by Martijn de Munnik
    I want to use DQL to create a query which looks like this in SQL: select e.* from e inner join ( select uuid, max(locale) as locale from e where locale = 'nl_NL' or locale = 'nl' group by uuid ) as e_ on e.uuid = e_.uuid and e.locale = e_.locale I tried to use QueryBuilder to generate the query and subquery. I think they do the right thing by them selves but I can't combine them in the join statement. Does anybody now if this is possible with DQL? I can't use native SQL because I want to return real objects and I don't know for which object this query is run (I only know the base class which have the uuid and locale property). $subQueryBuilder = $this->_em->createQueryBuilder(); $subQueryBuilder ->addSelect('e.uuid, max(e.locale) as locale') ->from($this->_entityName, 'e') ->where($subQueryBuilder->expr()->in('e.locale', $localeCriteria)) ->groupBy('e.uuid'); $queryBuilder = $this->_em->createQueryBuilder(); $queryBuilder ->addSelect('e') ->from($this->_entityName, 'e') ->join('('.$subQueryBuilder.') as', 'e_')->join ->where('e.uuid = e_.uuid') ->andWhere('e.locale = e_.locale');

  • A good Sorted List for Java

    - by Phuong Nguyen de ManCity fan
    I'm looking for a good sorted list for java. Googling around give me some hints about using TreeSet/TreeMap. But these components is lack of one thing: random access to an element in the set. For example, I want to access nth element in the sorted set, but with TreeSet, I must iterate over other n-1 elements before I can get there. It would be a waste since I would have upto several thousands elements in my Set. Basically, I'm looking for some thing similar to a sorted list in .NET, with ability to add element fast, remove element fast, and have random access to any element in the list. Has this kind of sorted list implemented somewhere? Thanks.

  • Extension method return using generics

    - by Steven de Salas
    Is it possible to return a generic type using extension methods? For example, I have the following method: // Convenience method to obtain a field within a row (as a double type) public static double GetDouble(this DataRow row, string field) { if (row != null && row.Table.Columns.Contains(field)) { object value = row[field]; if (value != null && value != DBNull.Value) return Convert.ToDouble(value); } return 0; } This is currently used as follows: double value = row.GetDouble("tangible-equity"); but I would like to use the following code: double value = row.Get<double>("tangible-equity"); Is this possible and if so, what would the method look like?

  • Opening an Excel file in c#

    - by Jan de Jager
    So there are a lot of questions regarding this method on SO, but none seem to answer my question. I firstly had an issue with the connectionstring (although it seems to work in other areas of my code correctly). This was resolved easily. Now the issue is with a simple SELECT query via a OLEDBCommand (Text) that keeps popping up the following error? "SELECT [Opportunity#],[BidManager],[Prob %],[Opportunity_Stage].[Opportunity_Status],[Term],[Sign Date] FROM [Sheet1$];" No value given for one or more required parameters. but their are no parameters???? Checked and double checked the columns names, but to no avail. Also tried removing the special characters from the column names, but still the same exception.

  • HD Crash SQL server -> DBCC - consistency errors in table 'sysindexes'

    - by Julian de Wit
    Hello A client of mine has had an HD crash an a SQL DB got corrupt : They did not make backups so they have a big problem. When I tried (an ultimate measure) to DBCC-repair I got the following message. Can anybody help me with this ? Server: Msg 8966, Level 16, State 1, Line 1 Could not read and latch page (1:872) with latch type SH. sysindexes failed. Server: Msg 8944, Level 16, State 1, Line 1 Table error: Object ID 2, index ID 0, page (1:872), row 11. Test (columnOffsets->IsComplex (varColumnNumber) && (ColumnId == COLID_HYDRA_TEXTPTR || ColumnId == COLID_INROW_ROOT || ColumnId == COLID_BACKPTR)) failed. Values are 2 and 5. The repair level on the DBCC statement caused this repair to be bypassed. CHECKTABLE found 0 allocation errors and 1 consistency errors in table 'sysindexes' (object ID 2). DBCC execution completed. If DBCC printed error messages, contact your system administrator.

  • Link to specific page on Google Document Viewer on iPad

    - by Debarupa De
    I am thinking of using the Google Document Viewer to show PDF files that are hosted by our company server. The scenario is: A webpage will contain a menu with menu items that are actually different pages of a PDF file. After clicking a menu item, that particular page from the pdf will be displayed on that same web page This project is targeted for mobile devices (iPad, for now) Now, I am using an iFrame like below: But I don't know if linking to a specific page is possible or Google would like that because I tried the solutions posted on how to open specific page on Google's docs viewer and http://googlesystem.blogspot.com/2009/11/link-to-page-in-googles-document-viewer.html but all of them seem to be outdated. Is this even possible? Thanks for any help.

  • sudo changes PATH - why?

    - by Michiel de Mare
    This is the PATH variable without sudo: $ echo 'echo $PATH' | sh /opt/local/ruby/bin:/usr/bin:/bin This is the PATH variable with sudo: $echo 'echo $PATH' | sudo sh /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin As far as I can tell, sudo is supposed to leave PATH untouched. What's going on? How do I change this? (This is on Ubuntu 8.04). UPDATE: as far as I can see, none of the scripts started as root change PATH in any way. From man sudo: To prevent command spoofing, sudo checks ``.'' and ``'' (both denoting current directory) last when searching for a command in the user's PATH (if one or both are in the PATH). Note, however, that the actual PATH environment variable is not modified and is passed unchanged to the program that sudo executes.

  • infix operation to postfix using stacks

    - by Chris De La O
    We are writing a program that needs to convert an infix operation (4 5/3) to postfix (4 5 3 / ) using stacks. however my convert to postfix does not work as it doesnt not output the postFix array that is supposed to store the conversion from infix notation to postfix notation. here is the code for the convertToPostix fuction. //converts infix expression to postfix expression void ArithmeticExpression::convertToPostfix(char *const inFix, char *const postFix) { //create a stack2 object named cow Stack2<char> cow; cout<<postFix; char thing = '('; //push a left parenthesis onto the stack cow.push(thing); //append a right parenthesis to the end of inFix array strcat(inFix, ")"); int i = 0;//declare an int that will control posFix position //if the stack is not empty if (!cow.isEmpty()) { //loop to run until the last character in inFix array for (int x = 0; inFix[x]!= '\0'; x++ ) { //if the inFix element is a digit if (isdigit(inFix[x])) { postFix[i]=inFix[x];//it is assigned to the next element in postFix array i++;//move on to next element in postFix } //if the inFix element is a left parenthesis else if (inFix[x]=='(') { cow.push(inFix[x]);//push it unto the stack } //if the inFix element is an operator else if (isOperator(inFix[x])) { char oper2 = inFix[x];//char variable holds inFix operator if (isOperator(cow.stackTop()))//if the top node in the stack is an operator { while (isOperator(cow.stackTop()))//and while the top node in the stack is an operator { char oper1 = cow.stackTop();//char variable holds node operator if(precedence( oper1, oper2))//if the node operator has higher presedence than node operator { postFix[i] = cow.pop();//we pop such operator and insert it in postFix array's next element cow.push(inFix[x]);//and push inFix operator unto the stack i++;//move to the next element in posFix } } } //if the top node is not an operator //we push the current inFix operator unto the top of the stack else cow.push(inFix[x]); } //if the inFix element is a right parenthesis else if (inFix[x]==')') { //we pop everything in the stack and insert it in postFix //until we arrive at a left paranthesis while (cow.stackTop()!='(') { postFix[i] = cow.pop(); i++; } //we then pop and discard left parenthesis cow.pop(); } } postFix[i]='\0'; //print !!postFix array!!

  • Use a ContextLoaderListener in accordance with DispatchServlet

    - by Phuong Nguyen de ManCity fan
    I want to use both ContextLoaderListener (so that I can pass Spring Beans to my servlet) as well as DispatchServlet (Spring MVC). However, currently I have to pass init param to these both class initializer: <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/spring/app-config.xml </param-value> So, I use the same xml for these both classes. Wonder if it would lead to my beans being initialized twice? If yes, how would I do to avoid that?

  • Mutually beneficial IP/copyright clauses for contract-based freelance work

    - by Nathan de Vries
    I have a copyright section in the contract I give to my clients stating that I retain copyright on any works produced during my work for them as an independent contractor. This is most definitely not intended to place arbitrary restrictions on my clients, but rather to maintain my ability to decide on how the software I create is licensed and distributed. Almost every project I work on results in at least one part of it being released as open source. Every project I work on makes use of third-party software released in the same fashion, so returning the favour is something I would like to continue doing. Unfortunately, the contract is not so clear when it comes to defining the rights of the client in the use of said software. I mention that the code will be licensed to them, but do not mention specifics about exclusivity, ability to produce derivatives etc. As such, a client has raised concerns about the copyright section of my contract, and has suggested that I reword it such that all copyrights are transferred entirely to the client on final payment for the project. This will almost certainly reduce my ability to distribute the software I have created; I would much prefer to find a more mutually beneficial agreement where both our concerns are appeased. Are there any tried and true approaches to licensing software in this kind of situation? To summarise: I want to maintain the ability to license (parts of) the software under my own terms, independently of my relationship with the client; with some guarantee to the client that no trade-secrets or critical business logic will be shared; giving them the ability to re-use my code in their future projects; but not necessarily letting them sell it (I'm not sure about this, though...what happens if they sell their business and the software along with it?) I realise that everyone's feedback is going to be prefixed with "IANAL", however I appreciate any thoughts you might have on the matter.

  • Can I make the compiler and the CLR ignore non implemented interfaces on my types?

    - by Thiado de Arruda
    I would like to define a type implementing a certain interface, however I would only implement it in a proxy at runtime. I can see two obstacles in this scenario : 1-Make the compiler ignore non implemented interfaces. 2-Make the CLR ignore(or at least delay) the TypeLoadException with the following description : "Method SOMEMETHOD in type SOMETYPE from assembly SOMEASSEMBLY does not have an implementation." Is something like this possible?

  • How do I extend a WPF application using an addin-like architeture?

    - by Thiado de Arruda
    Lets say I have a WPF application that shows a ListBox with an ArrayList -populated with objects of arbitrary types- as a source, and this application is hosted in an assembly 'A'. By default the ListBox will display the custom object 'ToString' method return value. If a data template for that object type is found, the ListBox will use it for rendering. Imagine that theres another assembly 'B' that references of 'A' and seeks to extend it by providing custom data templates for certain types, to be used in that ListBox. Is there some way to do that without 'A'being aware of B?

  • Android add image to button

    - by Christiaan de Jong
    I want to add an image to a Button (no imagebutton, as the particular button can either contain text or an image; plus the imagebutton has the same problem), while still retaining the original android-style button. So adding android:background in the XML doesn't cut it, as that will remove the android default button with rounded corners etc. (android.R.drawable.btn_default) Is this in any way possible? I think one way is to make a 9patch image for the button pressed (one for up and one for down) and onTouch Action_DOWN make a layered background drawable and put that onto the button, and doing the same thing but with another 9patch for onTouch Action_UP, but I think that will decrease the performance of the application substantially, as that will require quite a lot of resource reading and layer merging for all the button clicks (and for my application, that will be quite a lot). Is what I state above correct?

  • Google maps z-index problem in IE

    - by Bas van de Lustgraaf
    I'm loading my google maps into div class="extra" style="display: none;" /. As soon as the AJAX request is complete, the map_canvas div is placed inside the hidden div and the hidden div will be vissible with the toggleDown jquery effect. In FF it's working perfect, but in IE the Google maps (map_canvas div) is already visible before the toggleDown effect is started. I think the z-index and the relative position of the map_canvas div wich is loaded into the hidden div will place the map_canvas div on top of the hidden div. What do i have to change to make sure the map_canvas div is not on top of the hidden div? While toggleDown in FF: http:// img169.imageshack.us/img169/9274/50485429.jpg While toggleDown in IE: http://img188.imageshack.us/img188/2110/93959677.jpg
