  • howto launch my application like MS-Office applications do using automation.

    - by Alan
    I am writing a c# application which references a separate dll which contains all the automation features i am trying to implement such as Application Object Model, doing all this by using delegates and events. What i want to be able todo is to reference my dll containing the application object model in a different process and for it to automatically launch my application, like MS-Word does when you call its application. Example: Microsoft.Office.Interop.Word.Application wordApp = new Microsoft.Office.Interop.Word.Application(); Word object model loads in the WinWord.exe running its own process how can i achieve this as well. Thanks in advance

  • Jmeter Query new user

    - by Sri
    First of all apologies for the below question. Am from a Testing background for the past 8 years and very novice to Jmeter. I went through the Jmeter site, and ran a sample recording using the jmeter.apache.org site and it went fine. I want to test my knowledge and understanding. So, I did the following way. Created a thread group. Added a config element HTTP Default Requests with server name as mail.google.com. Added a Sampler as HTTP request, set the METHOD to POST and gave the username and password, and i ran the test. When i see the Results Viewer, i could see the login page of gmail, I need to know how to pass my username and password and simulate the clicking of Submit button and getting the next page. Please help, am very new and will really appreciate if it's explained as simple as possible.

  • plld Prolog C++

    - by H.J. Miri
    I have a large Prolog program with lots of predicates. I need to connect to this Prolog code from C++ (VS2008) to obtain certain query results. So I am not trying to embed Prolog in C++ as a logicasl engine, but for my C++ program to connect to my Prolog code, consult (compile) it, obtain query results, and pass them back to C++. Running the following command at the VS2008 Command Prompt generates so many errors: plld -o myprog.exe mycpp.cpp mypl.pl Is there any way I can get my C++ program to consult my Prolog program, by including a command or makefile, etc...? I am aware that if you use VS2008, you are better off not using plld, so I am trying to include everything in one master C++ program, then press F5 to build and compile, and then call Prolog, then C++, and so on... Cheers,

  • In XHR, is it possible to distinguish network errors from cross-origin errors?

    - by greim
    http://www.w3.org/TR/access-control/ Reading the CORS spec linked above, it seems to be the case that it's impossible to reliably distinguish between a generic "network error" and a cross-origin access denied error. From the spec: If there is a network error Apply the network error steps. Perform a resource sharing check. If it returns fail, apply the network error steps. http://www.w3.org/TR/access-control/#simple-cross-origin-request0 In my testing, I couldn't locate any features of Firefox's implementation that seem to indicate that the resource sharing check definitely failed. It just switches readyState to 4 and sets status to 0. Ultimately I'd like the ability to pass a success callback, a general fail callback, and an optional cross-origin fail callback, to my function. Thanks for any help or insight.

  • any open source instant messenger?

    - by George2
    Hello everyone, I need to develop an instant messenger (like MSN Messagner, but only simple and basic function is fine), based on .Net (C#). I want to integrate the instant messenger with my current web site user. I want to know any open source (better C#) instant messenger to reference? BTW: some of the users are using internal IP address (behind a gateway or proxy, like 10.10.xxx.xxx) -- so in this scenario two users can not use point to point message transfer if both of them are behind a gateway? And I think I have to develop a server which acts as an intermediate party to transfer message between two users, correct? thanks in advance, George

  • Howto take a glimpse into mscorlib?

    - by panny
    Hi all! I want to read data into RSAParameters structure ( RSAParameters ) and did check twice, that the data is correct. But still, I get an error "invalid data" exception for this: bei System.Security.Cryptography.CryptographicException.ThrowCryptogaphicException(Int32 hr) bei System.Security.Cryptography.Utils._ImportKey(SafeProvHandle hCSP, Int32 keyNumber, CspProviderFlags flags, Object cspObject, SafeKeyHandle& hKey) bei System.Security.Cryptography.RSACryptoServiceProvider.ImportParameters(RSAParameters parameters) How can I take a look into the source code to check why _ImportKeys is throwing an exception? I have no experience with .dll 'decryption'..are there any symbols to reference somewhere for visual studio 8.0? Thank you.

  • What is the universal way to use file I/O API with unicode filenames?

    - by dma_k
    In Windows there is a common problem: the filenames should be converted to local codepage, before they are passed to open(). Of course, there is a possibility to use Win32::API for that, but I don't want my script to be platform-dependent. At the moment I have to write something like: open IN, "<", encode("cp1251", $filename) or die $!; but is there any library, that hides these details? I think the local codepage can be automatically detected, so I just want to pass unicode filename and forget about the details. Why is it still not in the box?

  • Cleaner way to store to replace a scalar hash value with an array ref?

    - by user275455
    I am building a hash where the keys, associated with scalars, are not necessarily unique. I want the desired behavior to be that if the key is unique, the value is the scalar. If the key is not unique, I want the value to be an array reference of the scalars associated witht the key. Since the hash is built up iteratively, I don't know if the key is unique ahead of time. Right now, I am doing something like this: if(!defined($hash{$key})){ $hash{$key} = $val; } elseif(ref($hash{$key}) ne 'ARRAY'){ my @a; push(@a, $hash{$key}); push(@, $val); $hash{$key} = \@a; } else{ push(@{$hash{$key}}, $val); } Is there a simpler way to do this?

  • Which class will be instantiated

    - by Michael
    Say I have 2 subclasses from UIViewController, class A and class B. In Main nib file an object is representing class A and it is set to load file from Secondary nib file. The owner of Secondary nib is of class B. The question is - from which class an object in Main nib file will be instanciated once the nib files unarchived in the memory? The reason this question arised is that I have to take care myself if such reference to external NIB file present, to ensure that the first nib's object and second nib's owner is same. Please correct me if my statement is wrong.

  • There is more then one Point class

    - by Dmitry
    Today I hit something very annoying while working with one of my colleagues. It seems there are two Point classes in .NET and by mistake we were trying for a good few minutes to figure out why our "Point(x,y)" wouldn’t take double, but only Int. Turns out we were using the wrong one since the XAML element in question needed the version with Double. So, based on what you actually want to do, make sure you’re using the right namespace. Please see below for MSDN reference links for each namespace version of Point, hope this saves you some time. System.Windows Point (MSDN Ref - Double version) System.Dawing Point (MSDN Ref - Int version)

  • using dummy row with NOT NULL to solve DEFAUT NULL

    - by Tony38
    I know having DEFAULT NULLS is not a good practice but I have many optional lookup values which are FK in the system so to solve this issue here is what i am doing: I use NOT NULL for every FK / lookup valve field. I have the first row in every table which is PK id = 1 as a dummy row with just "none" in all the columns. this way I can use NOT NULL in my schema and if needed reference to the none row values which should be null. Is this a good design or any other work arounds?

  • Are there any good materials or examples on creating a custom Designer in the Delphi IDE

    - by Mark Elder
    I am working on creating a custom form designer in the Delphi IDE. I'm trying to use the RegisterCustomModule, TBaseCustomModule, and ICustomModule functions, classes, and interfaces. My first question on this pointed me to the Delphi Developer's Handbook and the idea that I could even create a custom form designer. However, that book seems to be all Delphi 3 information and things have really changed since then. I'm not finding any material in the Delphi Help file, and searches have not returned very much. I did find the Accidental Programmer's page on the Open Tools, but that looks like it was last up dated in 1998? It does at least have the correct unit names and uses the new interfaces. I'm willing to track down and buy an older book if that is the best reference.

  • Ext.Button handler config option

    - by ppecher
    someClass = Ext.extend(someClassB, { _someFunctionC{ someButton = new Ext.button({ handler: function () { this._onClick('click'); } }), _onClick(someMessage){ Ext.Msg.alert(someMessage); } } } _onClick eats one parameter; in the above code you put in the 'click' event because you want _onClick to be executed after the user clicks on the button. However, how do you specify this specific 'click' registration AND pass in a local variable as the _onClick parameter at the same time? As an aside, why do you even have to specify 'click', when the API states that handler always pertains to a click? Is this additional information not unnecessary?

  • What features do you expect from a Java (Rich) Client Framework?

    - by Peter Walser
    I'm intending to design (and provide a reference implementation for) a new Swing Rich Client Framework. My job and personal experience covers many project-specific Swing client frameworks as well as the Eclipse RCP, and every one of them had some original and clever concepts, but also drawbacks and rigid realizations. My plan is to incorporate the best of those concepts and features into a new framework whose core is very open and extendable. For my must-have-features list, I'm counting on your input and hope you can share some concept pearls & diamonds you've encountered in other frameworks, or features you always wanted to have or have in a better way. The framework is intended for very simple to very complex and sophisticated projects for clients that need full i18n for richt clients that execute some or all of the non-presentation logic on the server to be very lightweight to be easy to learn and use Thanks in advance for sharing your insights :)

  • How do I create a create and execute an SQL command using OleDB directly?

    - by Pagis
    I want to use the OleDB interfaces directly to open a connection to a DB, create a command and executing it (for example using the ICommandText interface). The main thing I can't find is how to create the connection and the command object and how to connect the object that implements the ICommandText to the connection. In ADO I would just use the ActiveConnection property but I want to do this directly on the OleDB interfaces. Also, if anyone can recommend a tutorial to OleDB, ether online or a book, free or not that would be great (but a tutorial and not just a reference / API) I'm using C++ but any native code would be fine.

  • A problem with .NET 2.0 project, using a 3.0 DLL which implements WCF services.

    - by avance70
    I made a client for accessing my WCF services in one project, and all classes that work with services inherit from this class: public abstract class ServiceClient<TServiceClient> : IDisposable where TServiceClient : ICommunicationObject This class is where I do stuff like disposing, logging when the client was called, etc. some common stuff which all service classes would normally do. Everything worked fine, until I got the task to implement this on an old system. I got into a problem when I used this project (DLL) in an other project which cannot reference System.ServiceModel (since it's an old .NET 2.0 software that I still maintain, and upgrading it to 3.0 is out of the question). Here, if I omit where TServiceClient : ICommunicationObject then the project can build, but the ServiceClient cannot use, for example, client.Close() or client.State So, is my only solution to drop the where statement, and rewrite the service classes?

  • Help with SQL query

    - by user154301
    Hello, I have list of DateTime values, and for each value I need to fetch something from the database. I would like to do this with one query. I know it's possible to pass a table (list) to the stored procedure, but Im not sure how to write the query itself. Let's say I have the following table: CREATE TABLE Shows( ShowId [int] NOT NULL, StartTime DateTime NOT NULL, EndTime DateTime NOT NULL ) and an array of dates DECLARE @myDateArray MyCustomDateArrayType Now, if I were fetching a single item, I would write a query like this: SELECT * FROM Shows WHERE StartTime > @ArrayItem and @ArrayItem < EndTime where @ArrayItem is an item from @myDateArray . But how do I formulate the query that would fetch the information for all array items? Thanks!

  • Transparently storing class state without exposing implementation

    - by RoToRa
    I have a model (MVC) class whose internal state (which basically contains of private int fields) I want to store. The program is running on Android (for now) so I need to store the in a Bundle, but I'll be using the same class later in a desktop application where I'll have to store the state some other way, so I can't reference Bundle directly in my class. So my question is: What is the best way to store (and retrieve) the state of a class without exposing it's implementation? The best I could think of removing the private access modifier so that the fields become package accessible and create read/write helper classes in the same package, but that somehow seems wrong.

  • Passing arguments to javascript file, how does it work?

    - by vietean
    From the tutorial ScriptJSONOptions of FirebugLite page, I found the below: Script JSON options It is possible to set options using a JSON object inside the linked script: <script type="text/javascript" src="https://getfirebug.com/firebug-lite.js"> { overrideConsole: false, startInNewWindow: true, startOpened: true, enableTrace: true } </script> It means that we can pass the arguments to javascript file. But I don't know how does it work? Update: My question is how to get the arguments inside the js file? P/S: I also looked into code, but I could not find the code is implemented this feature.

  • Windows development: x86 to x64 transition

    - by Kerido
    Hi everybody. Are there any guidelines how to transit to x64 with as little pain as possible? Suppose, I have a windows native x86 executable written in C++. The EXE works fine by itself, but there is also DLL that is hosted by both, the former EXE and an outside x64 process. With setup like this, what parts would I need to rewrite? I would appreciate a more general answer or maybe a link to a reference where some theoretical background is given. Thanks

  • Django: do I need to do HttpResponseRedirect to render a simple string after a POST?

    - by AP257
    I've got a mobile app that makes POST requests to a Django site. I want to return a simple string (not a template-based page) after the app makes the POST request, saying 'Success' or 'Failure' as appropriate. However I know that after a POST request in Django you're supposed to do a HttpResponseRedirect. But, do I really need to redirect to another page and write a new function to handle it, all to output a string? And if so, how do I pass the success/failure status of the app in the HttpResponseRedirect, since it's only supposed to take one argument? Thanks!
