  • Microsoft Enterprise Logging Application Block - Reading Log File

    - by Or A
    Hi, I'm using MS log application block for logging my application event into a file called app-trace.log which located on the c:\temp folder. I'm trying to find the best way to read this file at runtime and display it when the user asks for it. now i have 2 issues: it seems that this kind of feature is not supported by the framework, hence i have to write this reader myself. am i missing something here? is there any better way of getting this data (w/o buffering it in the memory or saving it into another file). if i'm taking the only alternative that left for me, and implementing the reader myself, when i'm tring to do: System.IO.FileStream fs = new System.IO.FileStream(@"c:\temp\app-trace.log", FileMode.Open, FileAccess.Read); i'm getting "File being used by another process c#", probably the file is locked by the application block. is there any way to access and read it anyhow? Thank

  • Read Velocity Tokens/Tag from .vm file

    - by user1801660
    I have an application where in I am trying to create a velocity template repository which will help me centralise all my email templates and will allow me to create a communication hub. All templates will be called at runtime and populates with data via services. My problem is that I need to provide users with optional and compulsory params list when they define the template inputs for the velocity template. Is there a way to read the tokens/tags from the velocity template file and extract them?? Like I want a list of tokens $name.address.streetName to be available to me from .vm file. I do not want to go for Regex . I do not have to cache or reuse them , its just going to be a one time read and store the default,compulsory & optional params in the database. I am following these patterns : http://kickjava.com/src/org/apache/velocity/test/view/TemplateNodeView.java.htm How to use String as Velocity Template? Please advice.

  • NSMutableRequest skd problem

    - by user2164
    Hi, I am trying to make a web call with the iPhone. I have done this before and it works fine but now I can't make it work. I am trying to use the following method call which the documentation says is availble in 2.0 and later: - (void)addValue:(NSString *)value forHTTPHeaderField:(NSString *)field; I am attempting to build for version 3.2 and 4.0. NSMutableURLRequest *request = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:30]; [request addValue:@"0" forHTTPHeaderField:@"Content-Length"]; The error that I'm getting is a runtime error that says "-[NSURLRequest addValue:forHTTPHeaderField:]: unrecognized selector sent to instance 0x600e0c0" Can anyone tell me what I am missing that stops this code from working? Thanks.

  • Entity Framework .Include() with compile time checking?

    - by Mikey Cee
    Consider the following code, which is calling against an EF generated data context: var context = new DataContext(); var employees = context.Employees.Include("Department"); If I change the name of the entity Department then this code is going to start throwing a runtime error. So I'll have to do some kind of find and replace throughout my code to replace each occurrence of "Department". Is there any way to call the .Include() method in a safe manner, so I get compile time checking for all the entity names being referenced?

  • How do I dynamically create Flex 4 AddChild actions for States?

    - by TK Kocheran
    I have an application in which I need to create mx.states.State objects on the fly, as I'm reading external data in order to create the states. Each State only has a single child, so here's my code which I was using to accomplish this: var state:State = new State(); state.name = "a"; state.overrides = [new AddChild(parent, DisplayObject(view))]; this.states.push(state); However, when I actually change a state, I get a runtime error relating to the fact that you can't call addChild on a spark.components.Group component. Is there an equivalent AddElement action for adding elements to a Group during a state change?

  • [dynamic] Different behaviours between .NET 4.0 beta 2 and last release of .NET 4.0 !

    - by yogi4ever
    Hi. I've identified a difference of DLR between .NET 4.0 Beta 2 and the last release of .NET 4.0. In .NET 4.0 Beta 2, this code perfectly works at runtime : var dateTimeList = new List(); dynamic myDynamicObject = dateTimeList; object value = DateTime.Now; myDynamicObject.Add(value); Now, with last release of .NET 4.0, I have an exception at run time (to solve myDynamicObject.Add(value);) :-( In my real code, 'myDynamicObject' is a dynamic (but I know that it is always an ObservableCollection where T can be anything). 'value' is an instance which was got by some reflexions. As 'value' can have any type, the type of 'value' is Object. Do you see how can I solve this new limitation of .NET 4.0 ? Thanks

  • How reduce dll size again

    - by cemick
    My dll have been bigger multiplied up many times than early for some reason. I begining to size up the situation: A source hasn't changed. Debug information everywhere turned off. Dll use package "Pack", but not include in Runtime Packages options. I've compared new dll with old version dll thought the instrumentality of PE Explore. In new dll I find out many modules with prefix 'ec' implicitly imported unlike old dll. Package "Pack" using ecControls components Dll doesn't using explicitly call to ecControls units. Why ecControls units imported in dll? Have anybody some advice?

  • How do you detect an area that can be filled in in a bitmap in ActionScript 3?

    - by 1.21 gigawatts
    I am having a tough time figuring this out. I need to be able to detect a fill area for something similar to a coloring book picture. The user will click inside the area that needs to be filled. The image is user created bitmap content and so the fill area must be detected at runtime. Any help would be tremendously appreciated! Posting Flex 4 code for review: <fx:Script> <![CDATA[ protected function myImage_clickHandler(event:MouseEvent):void { myImage.imageDisplay.bitmapData.floodFill(event.localX,event.localY,0xFFFFFF); } ]]> </fx:Script> <s:Image id="myImage" click="myImage_clickHandler(event)" source="/images/square.gif"/>

Could any one help me what could be wrong in this?

  • How can i create a ModalPopupExtender control dynamically from a server control?

    - by Colour Blend
    I have a composite server control that does quiet a number of things; one of which is to display a ModalPopup OnClick of a dynamically generated HtmlAnchor control. I need to create this ModalPopupExtender control dynamically in my server control and trigger it from within. I have been able to create it and trigger it from a button created at design time but not at runtime. This is as a result of the ID assign to the link is always not found by the ModalPopupExtender control. I have tried assigning a static ID but no success. Can anyone help?

  • How to make a resolution independent camera preview on android?

    - by histeria
    Hi all, I'm making an android 1.6 app that uses phone's camera. In order to do this app resolution independent, I need to set a compatible aspect ratio for previewing camera on a SurfaceLayout. In 1.6 sdk there is no way to get supported sizes for the camera preview. It is possible to use a 4:3 or 3:2 aspect ratio and get no errors whith that? On the other hand, I need a way to make a xml layout that represents this Surfacelayout in this (unknown) aspect ratio in every resolution. I assume that is not possible to change the SurfaceLayout size in runtime. Can I do it with "dp" units? The other way is making this layout programmatically? There are some apps like Vignette or android camera application with some tricks to make something like that, like black bars (vignette) or fixed buttons bar, but I don't know how to do it in any kind of resolution. Any ideas? Thanks!

  • Generically creating objects in C#

    - by DrLazer
    What I am trying to do is load in objects from an XML save file. The problem is those objects are configurable by the user at runtime, meaning i had to use reflection to get the names and attributes of those objects stored in an XML file. I am in the middle of a recursive loop through the XML and up to the part where I need to create an object then thought ..... ah - no idea how to do that :( I have an array stuffed with empty objects (m_MenuDataTypes), one of each possible type. My recursive loading function looks like this private void LoadMenuData(XmlNode menuDataNode) { foreach (object menuDataObject in m_MenuDataTypes) { Type menuDataObjectType = menuDataObject.GetType(); if (menuDataObjectType.Name == menuDataNode.Name) { //create object } } } I need to put some code where my comment is but I can't have a big switch statement or anything. The objects in my array can change depending on how the user has configured the app.

  • Pattern Matching of Units of Measure in F#

Is there any way how to pattern match units of measure?

  • NSTableView doesn't populate with array objects until a new object is added via the controller

    - by Luke
    I have an NSTableView and an array controller set up as shown here, using cocoa bindings: https://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/TableView/PopulatingViewTablesWithBindings/PopulatingView-TablesWithBindings.html#//apple_ref/doc/uid/10000026i-CH13-SW3 In my app delegate during applicationDidFinishLaunching I have the following snippet in here, initialising the array and filling it with objects array = [[NSMutableArray alloc] init]; SomeObject* foo = [[Object alloc] init]; foo.text = @"sup"; [array addObject:foo]; //Repeat this a few times However, when I build the app and run it I end up with an empty table. However, if I bind a button to the array controller's add: input and click it during runtime (this adds a new object to the array and table) then the table will show the new object first, with the objects added during applicationDidFinishLaunching following it. Why does this happen? And is there a way to make my table populate without having to add an element first?

  • "Make" system for Actionscript?

    - by Ender
    In working on larger Actionscript/Flash projects, I've started to really feel the need for some kind of "make" system, but I haven't found it yet. Does anyone know if it exists? Required features: Ability to associate SWCs with their source code and/or FLAs i.e. "this swc is compiled from this source" Ability to mark my current project as depending on these SWCs (either as compile-time or runtime libraries) A single, big shiny button, that when pressed does the following: Checks to see if any of the source files have changed, and if so, recompiles their associated SWCs Recompiles and relinks the main .swf, if necessary Runs the main .swf Have yet to find a way to get something like FlashDevelop to do this (but I don't know it well enough to be sure). Support for both code and FLA sources is preferred.

  • Using Boost statechart, how can I transition to a state unconditionally?

    - by nickb
    I have a state A that I would like to transition to its next state B unconditionally, once the constructor of A has completed. Is this possible? I tried posting an event from the constructor, which does not work, even though it compiles. Thanks. Edit: Here is what I've tried so far: struct A : sc::simple_state< A, Active > { public: typedef sc::custom_reaction< EventDoneA > reactions; A() { std::cout << "Inside of A()" << std::endl; post_event( EventDoneA() ); } sc::result react( const EventDoneA & ) { return transit< B >(); } }; This yields the following runtime assertion failure: Assertion failed: get_pointer( pContext_ ) != 0, file /includ e/boost/statechart/simple_state.hpp, line 459

  • Access variable value using string representing variable's name

    - by Paul Ridgway
    Hello everyone, If the title was not clear, I will try to clarify what I am asking: Imagine I have a variable called counter, I know I can see its current value by doing something like: std::cout << counter << std::endl; However, assume I have lots of variables and I don't know which I'm going to want to look at until runtime. Does anyone know a way I can fetch the value of a variable by using its name, for example: std::cout << valueOf("counter") << std::endl; I feel being able to do this might make debugging large complex projects easier. Thanks in advance for your time.

  • About first-,second- and third-class value

    - by forest58
    First-class value can be passed as an argument returned from a subroutine assigned into a variable. Second-class value just can be passed as an argument. Third-class value even can't be passed as an argument. Why should these things defined like that? As I understand, "can be passed as an argument" means it can be pushed into the runtime stack;"can be assigned into a variable" means it can be moved into a different location of the memory; "can be returned from a subroutine" almost has the same meaning of "can be assigned into a variable" since the returned value always be put into a known address, so first class value is totally "movable" or "dynamic",second class value is half "movable" , and third class value is just "static", such as labels in C/C++ which just can be addressed by goto statement, and you can't do nothing with that address except "goto" .Does My understanding make any sense? or what do these three kinds of values mean exactly?

  • Load python module not from a file

    - by user575061
    Hello, I've got some python code in a library that attempts to load a simple value from a module that will exist for the applications that use this library from somemodule import simplevalue Normally, the application that uses the library will have the module file and everything works fine. However, in the unit tests for this library the module does not exist. I know that I can create a temporary file and add that file to my path at runtime, but I was curious if there is a way in python to load something in to memory that would allow the above import to work. This is more of a curiosity, saying "add the module to your test path" is not helpful :P

  • Interesting or unique types encountered?

    - by user318904
    What is the most strange or unique type you have seen in a programming language? I was thinking the other day about a "random variable", ie whenever it is evaluated it yields a random value from some domain. It would require some runtime trickery. Also I bet there can be some interesting mapping of regular expressions into a type system. It does not necessarily have to be a built in or primitive type, but some random class that implements a domain specific type won't really be interesting just unique.
