  • Inserting instructions into method.

    - by Alix
    Hi, (First of all, this is a very lengthy post, but don't worry: I've already implemented all of it, I'm just asking your opinion.) I'm having trouble implementing the following; I'd appreciate some help: I get a Type as parameter. I define a subclass using reflection. Notice that I don't intend to modify the original type, but create a new one. I create a property per field of the original class, like so: [- ignore this text here; I had to add something or the formatting wouldn't work <-] public class OriginalClass { private int x; } public class Subclass : OriginalClass { private int x; public int X { get { return x; } set { x = value; } } } [This is number 4! Numbered lists don't work if you add code in between; sorry] For every method of the superclass, I create an analogous method in the subclass. The method's body must be the same except that I replace the instructions ldfld x with callvirt this.get_X, that is, instead of reading from the field directly I call the get accessor. I'm having trouble with step 4. I know you're not supposed to manipulate code like this, but I really need to. Here's what I've tried: Attempt #1: Use Mono.Cecil. This would allow me to parse the body of the method into human-readable Instructions, and easily replace instructions. However, the original type isn't in a .dll file, so I can't find a way to load it with Mono.Cecil. Writing the type to a .dll, then load it, then modify it and write the new type to disk (which I think is the way you create a type with Mono.Cecil), and then load it seems like a huge overhead. Attempt #2: Use Mono.Reflection. This would also allow me to parse the body into Instructions, but then I have no support for replacing instructions. I've implemented a very ugly and inefficient solution using Mono.Reflection, but it doesn't yet support methods that contain try-catch statements (although I guess I can implement this) and I'm concerned that there may be other scenarios in which it won't work, since I'm using the ILGenerator in a somewhat unusual way. Also, it's very ugly ;). Here's what I've done: private void TransformMethod(MethodInfo methodInfo) { // Create a method with the same signature. ParameterInfo[] paramList = methodInfo.GetParameters(); Type[] args = new Type[paramList.Length]; for (int i = 0; i < args.Length; i++) { args[i] = paramList[i].ParameterType; } MethodBuilder methodBuilder = typeBuilder.DefineMethod( methodInfo.Name, methodInfo.Attributes, methodInfo.ReturnType, args); ILGenerator ilGen = methodBuilder.GetILGenerator(); // Declare the same local variables as in the original method. IList<LocalVariableInfo> locals = methodInfo.GetMethodBody().LocalVariables; foreach (LocalVariableInfo local in locals) { ilGen.DeclareLocal(local.LocalType); } // Get readable instructions. IList<Instruction> instructions = methodInfo.GetInstructions(); // I first need to define labels for every instruction in case I // later find a jump to that instruction. Once the instruction has // been emitted I cannot label it, so I'll need to do it in advance. // Since I'm doing a first pass on the method's body anyway, I could // instead just create labels where they are truly needed, but for // now I'm using this quick fix. Dictionary<int, Label> labels = new Dictionary<int, Label>(); foreach (Instruction instr in instructions) { labels[instr.Offset] = ilGen.DefineLabel(); } foreach (Instruction instr in instructions) { // Mark this instruction with a label, in case there's a branch // instruction that jumps here. ilGen.MarkLabel(labels[instr.Offset]); // If this is the instruction that I want to replace (ldfld x)... if (instr.OpCode == OpCodes.Ldfld) { // ...get the get accessor for the accessed field (get_X()) // (I have the accessors in a dictionary; this isn't relevant), MethodInfo safeReadAccessor = dataMembersSafeAccessors[((FieldInfo) instr.Operand).Name][0]; // ...instead of emitting the original instruction (ldfld x), // emit a call to the get accessor, ilGen.Emit(OpCodes.Callvirt, safeReadAccessor); // Else (it's any other instruction), reemit the instruction, unaltered. } else { Reemit(instr, ilGen, labels); } } } And here comes the horrible, horrible Reemit method: private void Reemit(Instruction instr, ILGenerator ilGen, Dictionary<int, Label> labels) { // If the instruction doesn't have an operand, emit the opcode and return. if (instr.Operand == null) { ilGen.Emit(instr.OpCode); return; } // Else (it has an operand)... // If it's a branch instruction, retrieve the corresponding label (to // which we want to jump), emit the instruction and return. if (instr.OpCode.FlowControl == FlowControl.Branch) { ilGen.Emit(instr.OpCode, labels[Int32.Parse(instr.Operand.ToString())]); return; } // Otherwise, simply emit the instruction. I need to use the right // Emit call, so I need to cast the operand to its type. Type operandType = instr.Operand.GetType(); if (typeof(byte).IsAssignableFrom(operandType)) ilGen.Emit(instr.OpCode, (byte) instr.Operand); else if (typeof(double).IsAssignableFrom(operandType)) ilGen.Emit(instr.OpCode, (double) instr.Operand); else if (typeof(float).IsAssignableFrom(operandType)) ilGen.Emit(instr.OpCode, (float) instr.Operand); else if (typeof(int).IsAssignableFrom(operandType)) ilGen.Emit(instr.OpCode, (int) instr.Operand); ... // you get the idea. This is a pretty long method, all like this. } Branch instructions are a special case because instr.Operand is SByte, but Emit expects an operand of type Label. Hence the need for the Dictionary labels. As you can see, this is pretty horrible. What's more, it doesn't work in all cases, for instance with methods that contain try-catch statements, since I haven't emitted them using methods BeginExceptionBlock, BeginCatchBlock, etc, of ILGenerator. This is getting complicated. I guess I can do it: MethodBody has a list of ExceptionHandlingClause that should contain the necessary information to do this. But I don't like this solution anyway, so I'll save this as a last-resort solution. Attempt #3: Go bare-back and just copy the byte array returned by MethodBody.GetILAsByteArray(), since I only want to replace a single instruction for another single instruction of the same size that produces the exact same result: it loads the same type of object on the stack, etc. So there won't be any labels shifting and everything should work exactly the same. I've done this, replacing specific bytes of the array and then calling MethodBuilder.CreateMethodBody(byte[], int), but I still get the same error with exceptions, and I still need to declare the local variables or I'll get an error... even when I simply copy the method's body and don't change anything. So this is more efficient but I still have to take care of the exceptions, etc. Sigh. Here's the implementation of attempt #3, in case anyone is interested: private void TransformMethod(MethodInfo methodInfo, Dictionary<string, MethodInfo[]> dataMembersSafeAccessors, ModuleBuilder moduleBuilder) { ParameterInfo[] paramList = methodInfo.GetParameters(); Type[] args = new Type[paramList.Length]; for (int i = 0; i < args.Length; i++) { args[i] = paramList[i].ParameterType; } MethodBuilder methodBuilder = typeBuilder.DefineMethod( methodInfo.Name, methodInfo.Attributes, methodInfo.ReturnType, args); ILGenerator ilGen = methodBuilder.GetILGenerator(); IList<LocalVariableInfo> locals = methodInfo.GetMethodBody().LocalVariables; foreach (LocalVariableInfo local in locals) { ilGen.DeclareLocal(local.LocalType); } byte[] rawInstructions = methodInfo.GetMethodBody().GetILAsByteArray(); IList<Instruction> instructions = methodInfo.GetInstructions(); int k = 0; foreach (Instruction instr in instructions) { if (instr.OpCode == OpCodes.Ldfld) { MethodInfo safeReadAccessor = dataMembersSafeAccessors[((FieldInfo) instr.Operand).Name][0]; byte[] bytes = toByteArray(OpCodes.Callvirt.Value); for (int m = 0; m < OpCodes.Callvirt.Size; m++) { rawInstructions[k++] = bytes[put.Length - 1 - m]; } bytes = toByteArray(moduleBuilder.GetMethodToken(safeReadAccessor).Token); for (int m = instr.Size - OpCodes.Ldfld.Size - 1; m >= 0; m--) { rawInstructions[k++] = bytes[m]; } } else { k += instr.Size; } } methodBuilder.CreateMethodBody(rawInstructions, rawInstructions.Length); } private static byte[] toByteArray(int intValue) { byte[] intBytes = BitConverter.GetBytes(intValue); if (BitConverter.IsLittleEndian) Array.Reverse(intBytes); return intBytes; } private static byte[] toByteArray(short shortValue) { byte[] intBytes = BitConverter.GetBytes(shortValue); if (BitConverter.IsLittleEndian) Array.Reverse(intBytes); return intBytes; } (I know it isn't pretty. Sorry. I put it quickly together to see if it would work.) I don't have much hope, but can anyone suggest anything better than this? Sorry about the extremely lengthy post, and thanks.

  • MS SQL Error: Primary file group is full

    - by aximili
    I have a very large table in my database and I am starting to get this error Could not allocate a new page for database 'mydatabase' because of insufficient disk space in filegroup 'PRIMARY'. Create the necessary space by dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup. How do you fix this error? I don't understand the suggestions there.

  • Joining Multiple Projects in one solution

    - by PCAddict
    I have started creating a game, and I added a second project, it's the standard XNA Windows game 3.1 project, and since the other project already had a Main to start the program and the 2nd is for game data, where as the first was for the drawing and graphical side of things (menu's etc) I thought I would remove the Main method, and now all I get are Errors saying there isn't a Valid main method, I tried to make it dependant on the other (since this data is loaded at run time and is such as quests/items etc) but it still wont let me run the solution at all. the code for the main method is still in the 1st project, and if I delete the 2nd project it runs fine, although no game data so I only get menus... Thank you in advance for any assistance.

  • Rails: Custom template for email "deliver_" method?

    - by neezer
    I'm building an email system that stores my different emails in the database and calls the appropriate "deliver_" method via method_missing (since I can't explicitly declare methods since they're user-generated). My problem is that my rails app still tries to render the template for whatever the generated email is, though those templates don't exist. I want to force all emails to use the same template (views/test_email.html.haml), which will be setup to draw their formatting from my database records. How can I accomplish this? I tried adding render :template => 'test_email' in the test_email method in emailer_controller with no luck. models/emailer.rb: class Emailer < ActionMailer::Base def method_missing(method, *args) # not been implemented yet logger.info "method missing was called!!" end end controller/emailer_controller.rb: class EmailerController < ApplicationController def test_email @email = Email.find(params[:id]) Emailer.send("deliver_#{@email.name}") end end views/emails/index.html.haml: %h1 Listing emails %table{ :cellspacing => 0 } %tr %th Name %th Subject - @emails.each do |email| %tr %td=h email.name %td=h email.subject %td= link_to 'Show', email %td= link_to 'Edit', edit_email_path(email) %td= link_to 'Send Test Message', :controller => 'emailer', :action => 'test_email', :params => { :id => email.id } %td= link_to 'Destroy', email, :confirm => 'Are you sure?', :method => :delete %p= link_to 'New email', new_email_path Error I'm getting with the above: Template is missing Missing template emailer/name_of_email_in_database.erb in view path app/views

  • Need an algorithm to group several parameters of a person under the persons name

    - by QuickMist
    Hi. I have a bunch of names in alphabetical order with multiple instances of the same name all in alphabetical order so that the names are all grouped together. Beside each name, after a coma, I have a role that has been assigned to them, one name-role pair per line, something like whats shown below name1,role1 name1,role2 name1,role3 name1,role8 name2,role8 name2,role2 name2,role4 name3,role1 name4,role5 name4,role1 ... .. . I am looking for an algorithm to take the above .csv file as input create an output .csv file in the following format name1,role1,role2,role3,role8 name2,role8,role2,role4 name3,role1 name4,role5,role1 ... .. . So basically I want each name to appear only once and then the roles to be printed in csv format next to the names for all names and roles in the input file. The algorithm should be language independent. I would appreciate it if it does NOT use OOP principles :-) I am a newbie.

  • Making one of a group of similar form fields required in CakePHP

    - by Pickledegg
    I have a bunch of name/email fields in my form like this: data[Friend][0][name] data[Friend][1][name] data[Friend][2][name] etc. and data[Friend][0][email] data[Friend][1][email] data[Friend][2][email] etc. I have a custom validation rule on each one that checks to see if the corresponding field is filled in. Ie. if data[Friend][2][name] then data[Friend][2][email] MUST be filled in. FYI, heres what one of the two rules look like: My form validation rule: ( I have an email validation too but that's irrelevant here) 'name' => array( 'checkEmail' => array( 'rule' => 'hasEmail', 'message' => 'You must fill in the name field', 'last' => true ) ) My custom rule code: function hasEmail($data){ $name = array_values($data); $name = $name[0]; if(strlen($name) == 0){ return empty($this->data['Friend']['email']); } return true; } I need to make it so that one of the pairs should be filled in as a minimum. It can be any as long as the indexes correspond. I can't figure a way, as if I set the form rule to be required or allowEmpty false, it fails on ALL empty fields. How can I check for the existence of 1 pair and if present, carry on? Also, I need to strip out all of the remaining empty [Friend] fields, so my saveAll() doesn't save a load of empty rows, but I think I can handle that part using extract in my controller. The main problem is this validation. Thanks.

  • MYSQL Select and group by date

    - by Gil
    I'm not sure how create a right query to get the result I'm looking for. What I have is 2 tables. first has ID, Name columns and second has date and adminID, which is referenced from table 1 column ID. Now, what I want to get is basically number of times each admin loged in per day during the month. From structure like this one I want to get per day and month data so result would be similar to 1, 2, 2 march total 5 for admin 4. ID | Date ------------------ 4 | 2010/03/01 4 | 2010/03/04 4 | 2010/03/04 4 | 2010/03/05 4 | 2010/03/05

  • How to group data changes by operation with MySQL triggers

    - by Jan-Henk
    I am using triggers in MySQL to log changes to the data. These changes are recorded on a row level. I can now insert an entry in my log table for each row that is changed. However, I also need to record the operation to which the changes belong. For example, a delete operation like "DELETE * FROM table WHERE type=x" can delete multiple rows. With the trigger I can insert an entry for each deleted row into the log table, but I would like to also provide a unique identifier for the operation as a whole, so that the log table looks something like: log_id operation_id tablename fieldname oldvalue newvalue 1 1 table id 1 null 2 1 table type a null 3 1 table id 2 null 4 1 table type a null 5 2 table id 3 null 6 2 table type b null 7 2 table id 4 null 8 2 table type b null Is there a way in MySQL to identify the higher level operation to which the row changes belong? Or is this only possible by means of application level code? In the future it would also be nice to be able to record the transaction to which an operation belongs. Another question is if it is possible to capture the actual SQL query, besides using the query log. I don't think so myself, but maybe I am missing something. It is of course possible to capture these at the application level, but the goal is to keep intrusions to the application level code as minimal as possible. When this is not possible with MySQL, how is this with other database systems? For the current project it is not an option to use something other than MySQL, but it would be nice to know for future projects.

  • How to handle the pylint message: Warning: Method could be a function

    - by biffabacon
    Being new to Python, I decided to get some feedback on a class I'd written ASAP so I ran it against pylint. Is the message it gave "Warning: Method could be a function" telling me that it would be better to move this method out of the class because it doesn't use any instance variables? In c# I would make this a static method. What's the most pythonic thing to do here?

  • Between a jsf page and a managed bean, why the getter method is called twice

    - by Bariscan
    Hi, I have a jsf page with a form has an outputtext in it. The value of outputtext component is called from a backing bean (or managed bean). I know when I code it as #{MyBean.myString} Jsf rename it and calls getMyString() method. However the wierd thing is, when I put a breakpoint to the getter method of this component, I see it is called twice during the page is being rendered. The outputtext is in a h:form, and it is the only component wich is bind to a backingbean. I mean, it is so wierd that jsf should get the value when it first come to the getter method, however it needs to go to the getter method twice. Can you explain what is the reason of this behaviour in jsf? Any help would be appreciated, Best wishes, Baris

  • Pass enum value to method which is called by dynamic object

    - by user329588
    hello. I'm working on program which dynamically(in runtime) loads dlls. For an example: Microsoft.AnalysisServices.dll. In this dll we have this enum: namespace Microsoft.AnalysisServices { [Flags] public enum UpdateOptions { Default = 0, ExpandFull = 1, AlterDependents = 2, } } and we also have this class Cube: namespace Microsoft.AnalysisServices { public sealed class Cube : ... { public Cube(string name); public Cube(string name, string id); .. .. .. } } I dynamically load this dll and create object Cube. Than i call a method Cube.Update(). This method deploy Cube to SQL Analysis server. But if i want to call this method with parameters Cube.Update(UpdateOptions.ExpandFull) i get error, because method doesn't get appropriate parameter. I have already tried this, but doesn't work: dynamic updateOptions = AssemblyLoader.LoadStaticAssembly("Microsoft.AnalysisServices", "Microsoft.AnalysisServices.UpdateOptions");//my class for loading assembly Array s = Enum.GetNames(updateOptions); dynamic myEnumValue = s.GetValue(1);//1 = ExpandFull dynamicCube.Update(myEnumValue);// == Cube.Update(UpdateOptions.ExpandFull) I know that error is in parameter myEnumValue but i don't know how to get dynamically enum type from assembly and pass it to the method. Does anybody know the solution? Thank you very much for answers and help!

  • Standardizing a Release/Tools group on a specific language

    - by grahzny
    I'm part of a six-member build and release team for an embedded software company. We also support a lot of developer tools, such as Atlassian's Fisheye, Jira, etc., Perforce, Bugzilla, AnthillPro, and a couple of homebrew tools (like my Django release notes generator). Most of the time, our team just writes little plugins for larger apps (ex: customize workflows in Anthill), long-term utility scripts (package up a release for QA), or things like Perforce triggers (don't let people check into a specific branch unless their change description includes a bug number; authenticate against Active Directory instead of Perforce's internal passwords). That's about the scale of our problems, although we sometimes tackle something slightly more sizable. My boss, who is reasonably technical, has asked us to standardize on one or two languages so we can more easily substitute for each other. He's advocating bash scripts and Perl, due to their universality and simplicity. I can see his point--we mostly do "glue", so why not use "glue" languages rather than saddle ourselves with something designed for much larger projects? Since some of the tools we work with are Java-based, we do need to use something that speaks JVM sometimes. (The path of least resistance for these projects is BeanShell and Groovy.) I feel a tremendous itch toward language advocacy, but I'm trying to avoid saying "We should use Python 'cause I like it and Perl is gross." Instead, I'm trying to come up with a good approach to defining our problem set: what problems do we solve with scripts? Would we benefit from a library of common functions by our team, or are most of our projects more isolated? What is it reasonable to expect my co-workers to learn? What languages give us the most ease of development and ease of modification? Can you folks suggest some useful ways to approach this problem, both for my own thinking process and to help me facilitate some brainstorming among my coworkers?

  • Calling an Excel Add-In method from C# application or vice versa

    - by Jude
    I have an Excel VBA add-in with a public method in a bas file. This method currently creates a VB6 COM object, which exists in a running VB6 exe/vbp. The VB6 app loads in data and then the Excel add-in method can call methods on the VB6 COM object to load the data into an existing Excel xls. This is all currently working. We have since converted our VB6 app to C#. My question is: What is the best/easiest way to mimic this behavior with the C#/.NET app? I'm thinking I may not be able to pull the data from the .NET app into Excel from the add-in method since the .Net app needs to be running with data loaded (so no using a stand-alone C# class library). Maybe we can, instead, push the data from .NET to Excel by accessing the VBA add-in method from the C# code? The following is the existing VBA method accessing the VB6 app: Public Sub UpdateInDataFromApp() Dim wkbInData As Workbook Dim oFPW As Object Dim nMaxCols As Integer Dim nMaxRows As Integer Dim j As Integer Dim sName As String Dim nCol As Integer Dim nRow As Integer Dim sheetCnt As Integer Dim nDepth As Integer Dim sPath As String Dim vData As Variant Dim SheetRange As Range Set wkbInData = wkbOpen("InData.xls") sPath = g_sPathXLSfiles & "\" 'Note: the following will bring up fpw app if not already running Set oFPW = CreateObject("FPW.CProfilesData") If oFPW Is Nothing Then MsgBox "Unable to reference " & sApp Else . . . sheetCnt = wkbInData.Sheets.Count 'get number of sheets in indata workbook For j = 2 To sheetCnt 'set counter to loop over all sheets except the first one which is not input data fields With wkbInData.Worksheets(j) Set SheetRange = .UsedRange End With With SheetRange nMaxRows = .Rows.Count 'get range of sheet(j) nMaxCols = .Columns.Count 'get range of sheet(j) Range(.Cells(2, 2), .Cells(nMaxRows, nMaxCols)).ClearContents 'Clears data from data range (51 Columns) Range(.Cells(2, 2), .Cells(nMaxRows, nMaxCols)).ClearComments End With With oFPW 'vb6 object For nRow = 2 To nMaxRows ' loop through rows sName = SheetRange.Cells(nRow, 1) 'Field name vData = .vntGetSymbol(sName, 0) 'Check if vb6 app identifies the name nDepth = .GetInputTableDepth(sName) 'Get number of data items for this field name from vb6 app nMaxCols = nDepth + 2 'nDepth=0, is single data item For nCol = 2 To nMaxCols 'loop over deep screen fields nDepth = nCol - 2 'current depth vData = .vntGetSymbol(sName, nDepth) 'Get Data from vb6 app If LenB(vData) > 0 And IsNumeric(vData) Then 'Check if data returned SheetRange.Cells(nRow, nCol) = vData 'Poke the data in Else SheetRange.Cells(nRow, nCol) = vData 'Poke a zero in End If Next 'nCol Next 'nRow End With Set SheetRange = Nothing Next 'j End If Set wkbInData = Nothing Set oFPW = Nothing Exit Sub . . .

Here the code: \begin{tikzpicture}[node distance=1.5cm, auto, text centered] \tikzstyle{every node}=[draw,ball,align=center]; \begin{scope}[xshift=1.5cm] \node (A) {A}; \node [right of=A] (B) {B}; \node [right of=B] (C) {C}; \node [right of=C] (D) {D}; \end{scope} \begin{scope}[yshift=-1.5cm] \node (AB) {AB}; \node [right of=AB] (AC) {AC}; \node [right of=AC] (AD) {AD}; \node [right of=AD] (BC) {BC}; \node [right of=BC] (BD) {BD}; \node [right of=BD] (CD) {CD}; \end{scope} \begin{scope}[yshift=-3cm,node distance=2cm,xshift=1cm] \node (ABC) {ABC}; \node [right of=ABC] (ABD) {ABD}; \node [right of=ABD] (ACD) {ACD}; \node [right of=ACD] (BCD) {BCD}; \end{scope} \begin{scope}[xshift=4cm, yshift=-4.5cm, node distance=2cm] \node (ABCD) {ABCD}; \end{scope} \end{tikzpicture} Is there any other way to do it? Do not like to change xshift values every time.

  • sql query to return items based on text and group ID

    - by mattgcon
    I am not sure how to best describe what I am trying to do (or search for it for that matter) but I am going to try. I have a pre-existing query (stored procedure) that returns items based on 3 specific ID's. What I want to do is to be able to reduce the results even further based upon a column within the results having the exact same string. For some reason I am confused about how to do this, I am drawing a complete blank about this. Please help

  • FLEX: the custom component is still a Null Object when I invoke its method

    - by Patrick
    Hi, I've created a custom component in Flex, and I've created it from the main application with actionscript. Successively I invoke its "setName" method to pass a String. I get the following run-time error (occurring only if I use the setName method): TypeError: Error #1009: Cannot access a property or method of a null object reference. I guess I get it because I'm calling to newUser.setName method from main application before the component is completely created. How can I ask actionscript to "wait" until when the component is created to call the method ? Should I create an event listener in the main application waiting for it ? I would prefer to avoid it if possible. Here is the code: Main app ... newUser = new userComp(); //newUser.setName("name"); Component: <?xml version="1.0" encoding="utf-8"?> <mx:VBox xmlns:mx="http://www.adobe.com/2006/mxml" width="100" height="200" > <mx:Script> <![CDATA[ public function setName(name:String):void { username.text = name; } public function setTags(Tags:String):void { } ]]> </mx:Script> <mx:HBox id="tagsPopup" visible="false"> <mx:LinkButton label="Tag1" /> <mx:LinkButton label="Tag2" /> <mx:LinkButton label="Tag3" /> </mx:HBox> <mx:Image source="@Embed(source='../icons/userIcon.png')"/> <mx:Label id="username" text="Nickname" visible="false"/> </mx:VBox> thanks
