  • How to force visual styles when using .NET forms Interop from VB6

    - by Matt
    I have created a VB.NET Class Library that exposes some COM Interop sub routines. These in turn show various forms that are contained within the Class Library. When the forms are shown from VB6 they do not inherit the visual styles of the operating system and act like VB6 controls. I gather that this probably by design but is there some way to force/control visual styles manually in the .NET assembly? I would imagine that if I use a manifest in my VB6 app then everything will use the correct style but I would like to be able to control this myself if possible because we are using 3rd party controls in VB6 that do not require a manifest.

  • Is there an equivalence to CDOSYS AutoGenerateTextBody in .NET

    - by AnthonyWJones
    I'm porting some VBScript code which generates emails using the standard CDOSYS Message object. The Message oject has a property AutoGenerateTextBody which when true will cause it to automatically create the TextBody property value when you assign HTML to the HTMLBody property. Hence creating the typical text/plain and text/html alternatives in the message body. However .NET appears to be missing this function. The MailMessage object does have the ability to create alternative views but there doesn't appear to be a way to easily create the text body content from the HTML content. I'm not necessarily looking for an auto-magic option but I do need a solution to taking what is an HTML string and converting it to a reasonable plain text representation. Just dropping all the HTML markup doesn't cut it. Is there a tool buried somewhere in the existing .NET framework that can do this?

  • Google bot .net and AspxAutoDetectCookieSupport dilemma

    - by nLL
    Hi, i have a .net mobile web site where i use sesion state and due to nature of mobile networks/phones (not all supports session cookies) i had to use <sessionState cookieless="AutoDetect"/> It works fine but because each new session redirected with "AspxAutoDetectCookieSupport=1" i have a feeling that google won't like this. Here is a small sample from my server logs supportForumReadTopic.aspx id=38 80 - 66.249.71.80 Mozilla/5.0+(compatible;+Googlebot/2.1;++http://www.google.com/bot.html) 302 supportForumReadTopic.aspx id=38&AspxAutoDetectCookieSupport=1 Mozilla/5.0+(compatible;+Googlebot/2.1;++http://www.google.com/bot.html) 200 As you see each new hit from google will get 302 to itself. I have a genericmozilla5.browser file where i define google bot as cookie supporting browser in order to get .net not to use cookieless urls but not sure how this 302 would effect me. Any one had smilar exprience? Any ideas? Suggestions? Thanks

  • Writing a Compiler for .net - IL or Bytecode?

    - by Michael Stum
    I'm currently diving into the inner workings of .net, which means IL. As an exercise, I want to build a brainf..k compiler for .net (yes, they already exist, but as said it's for learning purposes). For the moment I'm just writing some text files that contain .il and compile them with ilasm, which works. But I wonder if I could/should go one level deeper and write bytecode directly? My "concern" is the Windows PE Stuff when compiling an EXE - instead of ilasm I would need some sort of Bytecode linker that would take my MSIL/CIL bytecode and generate the PE Stuff for it? Or do compilers "only" compile their language to IL and execute ilasm? Is there a managed version of it that I can call/embed from my compiler?

  • .net 4.0 concurrent queue dictionary

    - by freddy smith
    I would like to use the new concurrent collections in .NET 4.0 to solve the following problem. The basic data structure I want to have is a producer consumer queue, there will be a single consumer and multiple producers. There are items of type A,B,C,D,E that will be added to this queue. Items of type A,B,C are added to the queue in the normal manner and processed in order. However items of type D or E can only exist in the queue zero or once. If one of these is to be added and there already exists another of the same type that has not yet been processed then this should update that other one in-place in the queue. The queue position would not change (i.e. would not go to the back of the queue) after the update. Which .NET 4.0 classes would be best for this?

  • VisualBasic.net Database Boiler Plate

    - by Shiftbit
    Is there any built in .net Classes to assist in the reduction of boiler plate code? I have numerous database operations going on and I find that I am reproducing the connection, command, transaction and occassianlly data set. I am aware of the Java Related Question, however, the solutions pertain to Java. I was wondering if anyone was aware of a .net solution? http://stackoverflow.com/questions/1072925/remove-boilerplate-from-db-code Public Sub ReadData(ByVal connectionString As String) Dim queryString As String = "SELECT EmpNo, EName FROM Emp" Using connection As New OracleConnection(connectionString) Dim command As New OracleCommand(queryString, connection) connection.Open() Using reader As OracleDataReader = command.ExecuteReader() ' Always call Read before accessing data. While reader.Read() Console.WriteLine(reader.GetInt32(0).ToString() + ", " _ + reader.GetString(1)) End While End Using End Using End Sub MSDN

  • How to call an ASP.NET WebMethod using PowerShell?

    - by Domenic
    It seems like ASP.NET WebMethods are not "web servicey" enough to work with New-WebServiceProxy. Or maybe it is, and I haven't figured out how to initialize it? So instead, I tried doing it manually, like so: $wc = new-object System.Net.WebClient $wc.Credentials = [System.Net.CredentialCache]::DefaultCredentials $url = "http://www.domenicdenicola.com/AboutMe/SleepLog/default.aspx/GetSpans" $postData = "{`"starting`":`"\/Date(1254121200000)\/`",`"ending`":`"\/Date(1270018800000)\/`"}" $result = $wc.UploadString($url, $postData) But this gives me "The remote server returned an error: (500) Internal Server Error." So I must be doing something slightly wrong. Any ideas on how to call my PageMethod from PowerShell, and not get an error?

  • vb.net Object Initialiser List(Of T)

    - by Tim B James
    I have been looking at some C# code: List<Employee> Employees = new List<Employee>{ new Employee{firstname="Aamir",lastname="Hasan",age=20}, new Employee{firstname="awais",lastname="Hasan",age=50}, new Employee{firstname="Bill",lastname="Hasan",age=70}, new Employee{firstname="sobia",lastname="khan",age=80}, }; Now when I convert this to vb.net Dim Employees as List(Of Employee) = New List(Of Employee)() With { New Employee() With { _ .firstname = "Aamir", _ .lastname = "Hasan", _ .age = 20 _ }, _ New Employee() With { _ .firstname = "awais", _ .lastname = "Hasan", _ .age = 50 _ }, _ New Employee() With { _ .firstname = "Bill", _ .lastname = "Hasan", _ .age = 70 _ }, _ New Employee() With { _ .firstname = "sobia", _ .lastname = "khan", _ .age = 80 _ } _ } I get the error "Name of field or property being initialized in an object initializer must start with'.'." Now I can get an array of employee using the code: Dim Employees = { New Employee() With { _ .FirstName = "Aamir", _ .LastName = "Hasan", _ .Age = 20}, _ New Employee() With { _ .FirstName = "Awais", _ .LastName = "Hasan", _ .Age = 50}, _ New Employee() With { _ .FirstName = "Bill", _ .LastName = "Hasan", _ .Age = 70 _ } _ } But I would like a List(Of Employee) as it is bugging me as to why this doesnt work in vb.net?

  • How can I do rapid application development with ASP.NET MVC?

    - by Erik Forbes
    I've been given a short amount of time (~80 hours to start with) to replace an existing Access database with a full-blown SQL + Web system, and I'm enumerating my options. I would like to use ASP.NET MVC, but I'm unsure of how to use it effectively with my short timetable. For the database backend I'll be using Linq to SQL as it's a product I already know and can get something working with it quickly. Does anyone have any experience with using ASP.NET MVC in this way and can share some insight? Edit: The reason I've been interested in ASP.NET MVC is because I know (100% confirmed) that there will be more work to do after this first round, and I'd like my maintenance work to be as easy as possible. In my experience Webforms applications tend to break down over repeated maintenance, despite discipline. Maybe there's a middle ground? How difficult would it to be for me to, say, build the app with Webforms, then migrate it to MVC later when I have more time budgeted to the project? Edit 2: Further background: the Access application I'm replacing is used in some capacity by everyone in the building, and since it was upgraded from Access 98 to 2003 it's been crashing daily, causing hours of lost productivity as people have to re-enter data since the last backup. This is the reason for the short amount of time - this is a critical business function, and they can't afford to keep re-entering data on a daily basis.

  • Best disassembler tool for the .NET reflector?

    - by Joan Venge
    What's the best disassembler tool for the .NET reflector? By best I mean, saving a .NET assembly in a disassembled state in most readable, most likely to compile with fewer changes. The current one I use doesn't show simplified enumeration but shows the full IEnumerable implementations with MoveNext, etc with member names like: this.<4_state CS$<9_CachedAnonymousMethodDelegate3 Btw I am not trying to steal code, just trying out certain things on an already existing assembly instead of writing a similar thing from scratch. In the end, it's what I will learn from this that will stay, not the modified assembly.

  • Key logging in .NET

    - by Moshe
    Is it possible to write a key logger in Visual Basic.NET? Is this the right language to be using? So far, I've gotten a console app to read input and append to a file. 1)How can I make a .NET program "catch" all keyboard input? 2)How do I make a process not show up in Task Manager? This is not for a virus, but rather a parental control program for a specific clientele. No malicious intent here.

  • .NET library for generating javascript?

    - by Rune
    Do you know of a .NET library for generating javascript code? I want to generate javascript code based on information in my .NET application. I would like to be able to create an AST-like datastructure (using C#) and have it turned into valid javascript. I need to be able to create functions, statements, expressions etc., so I need something more than a JSON serializer - but I guess you could think of this as a (very) generalized JSON serializer. Do such libraries exist and if so, could you recommend any? Thank you.

  • Embedded web server and gui framework for .NET applications

    - by Toad
    Hi, I'm looking for a framework which allows me to manage my application through a webbased GUI (using an embedded webserver) instead of winforms. Something like this: http://www.webtoolkit.eu/wt but then for .NET In my code I should be able to instantiate classes (like buttons, forms etc), and when a user browses to a given port, the app should render it as javascript/ajax etc etc. preferably, when buttons are pushed, a notification in my code should be called. this is a less specific question than another one I posted about extjs. I hope this will attract more viewers since it is more generic Thanks. Update: cassini like solutions don't fit the bill. Since the webbrowser is embedded in my application, there is no need for ASP.NET server side scripts. I would rather have the framework, call functions inside my application when things happen on the page. onButtonClicked() for instance.

  • Strategies for Error Handling in .NET Web Services

    - by Jarrod
    I have a fairly substantial library of web services built in .NET that I use as a data model for our company web sites. In most .NET applications I use the Global ASAX file for profiling, logging, and creating bug reports for all exceptions thrown by the application. Global ASAX isn't available for web services so I'm curious as to what other strategies people have come up with to work around this limitation. Currently I just do something along these lines: <WebMethod()> _ Public Function MyServiceMethod(ByVal code As Integer) As String Try Return processCode(code) Catch ex As Exception CustomExHandler(ex) 'call a custom function every time to log exceptions Return errorObject End Try End Function Anybody have a better way of doing things besides calling a function inside the Catch?
