I�m using the my.computer.network.downloadfile (something like that) to download the html source to a text file. It has been working for about a year now.
Today it stopped working and the downloaded files are empty. I�ve talked to the people at the website, and they say they haven�t done anything. But they always say that.
Is there a way to "block" an automated download process of this kind, and how do I get around it?
I'm having trouble getting my archive service working. The service counts files in a directory and sends a email. Pretty simple. However, it randomly stops working. I debugged the service and found nothing wrong. I also have it writing to the eventlog so that I can use it to determine where it fails It progresses through each function normally. I thought my program was failing at on point, because it was only posting "Email Notification Service is Running". However, I realized it wasn't posting to the eventlog source so I've been playing around with different ways to post the message to the eventlog. Am I missing something from my code below? I'm really scratching my head with this one.

i tried updating my application on a vista home basic laptop. i get "myapp.exe has stopped working" then i restore back to the old version, it still give the same error. I am sure the old version is working because I tested it before updating it.

I want to download xsd specifications from a web service and automatic converting (serialize) these schemas to classes (visual studio - vb.net). If the organization that is responsible for the xsd schemas alter them in a way that only my class corresponding to the xsd have to be altered (not the rest of my code) I would like to automatic update my xsd corresponding class.
I use vs2010. What I want to do is: call a web service where I can send in an input parameter to the service which specifies the xsd I want to retrieve (the service is GetShemaDefenition and returns an object with the schema specification in a string property of the object). I den have to read the xsd string from the string property and convert this to a class representation of this xsd specification. Is it possible to do this automatically? I have done this manually by using xsd.exe. If the owner organization of the xsd has altered the xsd specification, I have to test if there is a new specification, and if there is I have to build a new class representation of this xsd? Is it possible to do what I want? And how would I know if it has been a big change in the xsd which also affect other parts of my code, not just the class representation of the xsd?
Update:I use one web service where one of the properties is a string. The string is an XML inside a CDATA block. The organization which provides the web service will not pares the xml inside the CDATA block but instead forward this to another organization that will use the xml data. The organization which uses the xml data specifies the xsd schem that I have to follow to generate my xml correct. This is the xsd schema I can get from another web service. I don't really understand what I can do with this xsd file from the web service. What can I do with it and why do I want to download it from the web service, when I can't use it automatically? Because I have to manually do the changes when the xsd changes I can easily download the xsd schema from the organization's home page and make the new class with xsd.exe.
So, I made an app on visual basic 2008, all cool and stuff, but now I'm experiencing a major problem. When I run my program it just works fine, but after some time (when I don't use the app) it suddenly changes from 42,5 KB to around 100 - 130 KB, and when I try to run it I get this error;The application failed to initialize properly 0xc000007B Click on ok to terminate the application.
So if I extract it again (zipped it), it works again and after some time I get the error again, so the file in the ''zip'' doesn't change.I can ensure I got no virus whatsoever on my computer, nor in my application.I just reinstalled my pc to see if it fixed the problem, it didn't
After successfully running an executable file several days ago, I am suddenly encountering a number of inexplicable errors. One concerns the lack of recognition of two libraries:
microsoft.office.core
microsoft.office.interop.excel
How could they previously be found but not now?I am using another workstation but loaded (so I thought) the same application and references.
ive been building a app, and have a beta tester who is on xp, im on vista x64, the app works great t my end, an dive also tested it on another pc with vista x64, and on a laptop wit win7 32, Now my beta teste has been testing fine on hes xp rig, up untill today when the WIP build i sent him started kicking up errors all over the place, try as i might i cant narrow it down to were the error is, heres how the app looks on vista and win7:[code]So i thought it might of been something i changed in between the working xp version and the wip but, all i changed was the page title, nothing else, no code etc.
View 4 RepliesThe user has been running the app in question for over a year with no issues like this (this is a VB2008 business/database application with an executable 4.6 MB in size). Starting last week, "all of a sudden", the user started getting INTERMITTENT error messages like the following:
Exception has been thrown by the target of an invocation.
Creation of the ImageList handle did not succeed.
Out of memory.
Parameter is not valid.
The last two have been accompanied by the big "red cross" on the form (in the screen shots the user sent me).The fact that the one message mentions "ImageList" and poking around on the Internet for answer on "Parameter not valid" points in the direction of a graphic problem, but nothing has changed in this area for a long time, and the app only uses graphics in a very straightforward way, using images on buttons and menu items, but not doing any in-line graphics methods.

A routinely used application suddenly became impossible to access, with and error code indicating that the "VB Backup\Backup" file cannot be found. When I click File Open, the projects display as always. I select the application, double click the .sln file--and nothing happens. When I try to access the .vb file in Solution Explorer, it says "Cannot find VB Backup\Backup Files."
What are the Backup Files, when are they created, and why would they suddenly be "gone?" Is there any way to rebuild the Backup Files? I used the application last night and it worked fine. Today it can't be opened because the Backup Files cannot be found.
I have backups of the application folders, but get the same error message. Cannot be opened because the Backup FIles cannot be found.

I am new in forum and in VB 2008 as well, I have a little background in VB6 I am making a program for a project and I need to calculate some mathematical formulas and the results I want to send them in an external device via serial port. To be more specific I have a function, like y(x)=a*x+y0. I get the starting and ending x and y from textbox and I calculate the respective y but I want to store each x and the resulting y(x) in order to send them after the completion of the complete calculation to the serial port.I have tried with datagrid view and dataset but I cannot fill the tables with the results.Does anyone have any idea what I can do.

View 1 RepliesI am trying to create a program that will have an option to automatically log you into a couple sites when you press the Start button. I have a separate form that you can open and put in your Username and Password for each site. There is a button that when you press it it is supposed to write to a file (C:DesktopAccounts.txt) you username and password so that when it is opened again you will not have to type them again. I had it working perfectly until I added some code so that it will remember if you had the check box checked and have the text box as read only (if check box is not checked). I even tried deleting the new code but it still will not write to the file, but it can read from it if I put the information in manually.

I have a VB.NET 2008 program that crashes about once a month at a customer location. My log file does not include any clues of the crash, the program just dies with the infamous SEND / DONT SEND window.So I need to setup my customers so that in the event of a program crash, a DUMP file is created automatically, without any user intervention. Everything I read on internet indicates that the drwtsn32.exe program does that.
View 3 RepliesI'm using Visual Studio 2008 on an XP machine and am trying to develop a web app that can interact with websites and carry out automatic tasks.One problem I have is trying to recreate the web requests for automatic interaction.
For example:I use a webBrowser control to allow me to surf a page manually. Then, once I am at a specific location, I'd like the automatic interaction to take over.Part of the website requires a log-in and exchanges cookie data.When I try to read the cookie info from the webbrowser control to build the subsequent automatic requests, the cookie content is incomplete.Upon further investigation, it appears that the site sets one of the cookies to "http only". This stops the value being visible to the webbrowser control.Is there another control or method I could use to retrieve this info?
For no reason I can discern my Visual Studio 2008 app (MyApp), which had many forms and reports, suddenly contains only one form, a simple test form I was experimenting with. I am unaware of any problem with the app. I use it to maintain an Access database which is still functional and is in the same place on the disk as it always did. This app and its data are all contained on my laptop computer. The form files all remain where they always did. I used to be able to control my earlier VB6 version of this application if it went off the rails, but I'm in the dark with VS2008.
View 7 RepliesI recently had to format my PC, So I moved my project files and build files to my External Hard Drive, and continued to work on my project..I started to receive emails saying that the application is saying "Cannot download the application. The application is missing required files. Contact application vendor for assistance." After clicked view details, I found this:+ Downloading file:///C:/Users/myuser/Downloads/Browser.application did not succeed.I was confused, the .application file is not in Downloads, its supposed to download it from my website. And if I were to open my project on a computer with it already installed, it won't check for updates - it opens really quick without the "Viewing Application Requirments" window.

View 2 Repliesi have this application, that creates various custom AppDomains, each app domain executes a assembly and its dependencies, like a plugin, a separated assembly, that manipulates database, own resources, etc.
the application runs fine for a while, but suddenly, it locks up... the process does NOT die, it just freezes, i ran a remote debugger on top of it, on the thread window i can see EVERY thread, they are with the status "running" (not "thaw") but, in the same place, not executing. i can pause and run the debug, and it remains in the same place. there are NO locks, synlocks, monitors, on the code and the code for loading the appdomains is very simple, no big deal on it. like i said, its working, but after a while, it locks up. Any ideas on this environment?
I've been cloning my objects using serialization for awhile, and typically its been quick, at least for my purposes. After a series of updates to these objects, however, now the serialization process is much slower. Trial-and-error has so far failed to pinpoint the cause. Some of the added elements to my object are:
1.binding lists
2. an inherited dictionary class
3. more internal references (the object is actually group of nested objects, and these internal objects have more references to each other than before)
I have been careful to avoid/eliminate references to external elements when cloning, as that can lead to a cascade of extra cloning. So I think the problem is with the object structure itself. This is my serialization routine:
Friend Function CloneObj(ByVal obj As Object) As Object
If Not obj.GetType.IsSerializable Then Throw New Exception("Object not serializable")
Dim bf As New System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
