Asp.net - Cannot Create A Process In A COM Object (written In .Net4) From An Asp (vbscript) Site?
Jan 14, 2011
I'm updating an old process that already exists, which works as follows:The user submits a form which runs the following asp (simplified, names changed):
I am trying to run simple application (e.g. generated from template by VS.NET 2010) on IIS6. I changed it to run with .NET 4.0 (its application pool) and checked with regiis (this pool has 4.0). I also changed all possible httpHandlers (svc etc), to run with NET4.0. All possible rights are checked (i think so). Almost every request results in "Server Application Unavailable" (sometimes it is empty page with -2146232576 (0x80131700) value) and "...Please review this log entry to discover what caused this error to occur." but EventViewer and IIS Log are empty.
We have a site and a logged in section of the site that all was written in classic asp. We are starting to convert the site pages to asp.net 3.5. We are starting with the easiest pages (text mainly) first then we will rewrite the web application part of the site.My question is - Is it possible to run the new asp.net 3.5 pages with classic asp pages? Or will we need to rewrite everything before deploying?
I have been struggling to get vbscript working for last three days of relentless effort. I have windows 7 ultimate and upgraded from windows vista. searched the web for solutions and tried out all the options I think I have, but yet no luck.
I tried registering vbscript.dll and I get a succeeded message back. Everything seems to be fine. but, I just cannot run vbscript on my computer. It complains that "can't find script engine vbscript for script ....". I have a hunch that it is something to do with "microsfot security essentials (my virus protection software)" or with UAC.
I am trying to use my web browser control to get retrieve date from a specific page, including all sub-page content. Problem is some of the sub-pages are on a separate domain and thus I am getting a permission deigned error when i try to access the frame [through document.windows.frames(i).document].Is there any work around to do this, even if I have to manually change security settings? I tried turning all my settings in IE to allow and still same error. I will only be running the app locally and no one will be browsing on IE so I can literally change anything needed to get this to work (even install older version of IE which may allow it but can still handle JS processing).
Note the reason I am using web browser is a great majority of data I will be accessing is JS generated, so I need to access the DOM after JS processed / generated the HTML. Because of this, simply using SOCKETS to get the HTML is really not an option. Even if I had the HTML, I still need some type of engine to process all of the DOM elements based off javascript.
I am trying to start the process with the following parameters When I try to start it though I get an System.nullreferenceexception: Object reference not set to an instance of an object
Dim exepath As String = Application.StartupPath + "inffmpeg.exe" Dim sr As StreamReader Dim cmd As String = " -i """ + input + """ -ar 22050 -y """ + output + """" Dim ffmpegOutput As String
I am trying to have multiple threads run through an arraylist of object and process each object. My problem is that each thread processes every object in the array.So they are not working together on the job. I made sample application to show my problem. I think the problem is somewhere in my ThreadSub() Here is the
Imports System.Threading Public Class Form1 Dim myitems As New ArrayList
Im trying to convert the nServiceBus PubSub .net4 example into vb and I'm struggling at one point which I think is a language issue but I thought I would ask the experts. The code in question is from the publisher:
In my code I can easily use "where Obj.Feld = String", but using "where Obj.Feld.StartsWith("a")" doesn't work. See the following two functions:
[Code]...
The first function (byFileName) works fine. The second function (LikeFileName) doesn't. Using Startswith I get "Object reference not set to an instance of an object." What am I doing wrong?Database is an array of Objects, a structure consisting of strings
I am having trouble with the insert command, my code is:
Protected Sub btnTestator_Click(sender As Object, e As System.EventArgs) Handles btnTestator.Click Dim WillsDataSource As SqlDataSource = New SqlDataSource() WillsDataSource.ConnectionString = ConfigurationManager.ConnectionStrings("ConnectionString").ToString()
[code]....
aatblWills1 is my sql server table with 3 fields: WillID(PrimaryKey, integer auto increment); UserName(nvarchar(150)) and TestatorName(nvarchar(150)) (there are some other fields in the table but I've set them to allow nulls)I am not getting an error message, it is just not inserting any records into the database.
Im trying to create a program that will login to a site for me, and cant get it to work for some reason. The code on the site im logging on to looks like this
<!--<p class="pleaselogin">Please Log In!</p>--> <div style="MARGIN-TOP: 1px; COLOR: rgb(153,0,0); FONT-SIZE: 12px" ><b>Member Login</b></div> <br>Sign in for more FREE features and tools!<br><br> <form method="post" action="http://my.domain.com/login

I am not sure if this is possiable but I am looking to build an application that will login to a web site, navigate the site and download files. I would like to do this all in code and able to run multiple instances of the program to get information from many different web sites. Is something like this possiable in VB.net?
Ive got an app that holds a list of site we have, At each site there are a few devices. The idea is when they click on a site all the details for the site are loaded and then a second thread sits and pings each device to see if its live. Im trying to do this in a seperate thread so if they click another site while its still pinging them it doesn't wait before it switches site. This all seems to be workling fine except if you click through the sites quickly, when you do that it will eventually come up with
Quote:
{"Collection was modified; enumeration operation might not execute."}
The error flags up on the "Next" line in "ThreadedPing"
Thread stuff
Public Sub ThreadedPing(ByVal dt As DataTable) Try
When i publish my program i choose to let the application check for updates via a website and if their is one update automatically when the program starts. Is their a way were on the main user form i can make it so that the user can change the update site with out me building the program again with the new site. I want to do this becuase the site i use goes down alot so when i changed the update url no one was able to download the update for the new update server.
I'm deploying a VB.Net app (VS 2010 Pro) that requiers the user click a command button to open IE to a financial WEB site and download informaion from the site. The app works fine in every detail when installed on the development computer. But, on the target computer when the command button is clicked an unhandled exception occurs which says: System.IO. FileNotFoundException:File Not found.My code behind the button is Shell("C:Program Files (x86)Internet Exploreriexplore.exe www,fidelity.com",AppWinStyle.NormalFocus)
This works fine on the development computer. Do I need a way to code this as a relative path? If so,can you tell me how this is done?Throughout the app I have written relative paths to needed files using paths like (Open(Environment. GEtFolderPath (Environment. SpecialFoldder.Desktop) + "File Name). They all work fine when deployed.
I'm being asked to maintain several internal-only web apps for my company. For testing, after making my changes, I've created some staging sites which make use of separate databases. As such, if my users were to mistakenly use this site as if it were the production site, they may enter important data and wonder where it "disappeared" to thinking it was the production server.
I'd like to create a big banner of some sort across the top of the staging site (which ONLY appears on the staging site) to remind my users that they are on the test site. I'd like recommendations on the best way to do this, with the following considerations:
IDE: Visual Studio 2008 Server: Windows 2003 with IIS 6 Language: VB.NET 2.0
I know this is not the right place for this question but still I would like to create in Visual Studio a small site with related links based on what the current page is displaying, from what I understand it's about MVP/MVC
I have an object that is defined as a global variable based on custom class. Within that class I have an event that gets fired a certain intervals. These events are fired on the same thread as where the object is declared. How do I create a global object, but have the events within that object fire on a separate thread?
I am trying to write an VBA application in Excel 2010 using "Microsoft Soap Toolkit 3.0" on 64 bit Windows 7 to consume an web service. But i got an error while initializing an object of SoapClient30.
I was create Access database with Access 2003. I create VB project with Visual Studio 2005 Standard With connection wizzard I create coonect with this Access database, select all tablesI see this database inside Data sources and inside Server explorer Test connection is OK When I drag and drop table from Data sources, Wizzard don't create DataGridView, DataSourceBinding etc .. and I see popup window with mesage: Object reference not set to an instance of an object and then "game over"
Under component services, a COM+ component is used by the company, right-clicking it and choosing 'Activation' tab will show the 'constructor string' that is used for DB server connection by all applications. How can I access it the simplest way possible?
I have a class library that contains a number of classes. I would like to dynamically create an instance of one of these classes, set its properties, and call a method.
Example:
Public Interface IExample Sub DoSomething() End Interface Public Class ExampleClass
This is not to manage my own application's GDI leak but another that runs in conjunction. Basically, I want to know if the number of GDI objects for a given process has reached a certain limit. I just need a pointer to the right direction. Should I be doing a "stack walk"?
I have a vb.net application which runs as a service. I also have another Windows application that serves as the service interface.In brief the service watches some folders for new files and imports them into various databases. In the service I have an class called 'importFile' containing basic properties such as 'FileName' and 'ImportStatus'. With each new incoming file I create a new instance of 'importFile' and add it to a list object called myFiles which is of the type: List (of importFile).Currently in my service im writing a few object details (such as ImportStatus) to an XML config file which is in turn read by the service interface application. I want to expose more information from the service to the interface, and communicating via xml doesn't feel like its the most efficient method.My question is how do I expose live objects, such as 'myFiles' in my service to my interface application? I think this can be done via the Process class but all my efforts have so far failed.I'm thinking that the solution may look something like the following, but im not too sure what im doing and could be way off:
