View 1 RepliesI have a leagcy application written in VB6 which makes posts to URLs using the InternetExplorer.application object.Once a post is made i would like to be able to see the status which was returned (i.e. 404 - page not found)
I can't find any properties of the object which will give me this information,
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?

Out of 70 users of my application 2 are getting the following message when they to run the application... That assembly does not allow partially trusted callers. The reason for the error is that by default .net applications run from a network location have limited permissions. You need to use caspol.exe to add the network folder where your application is being run from to the Trusted Zone. If you do a search on these forums you will find plenty examples of how to do this. It is fairly simple. It will have to be done on every machine that will be running the application and a simple cmd file can be made to do this. The only difference is that I've asked our service desk to install the application to the local C drive which I believe they did.

In my vb.net applications, I do a lot of reading/writing to excel files.This is one of the simpler bits of code I use:
Dim objApp As Object, objBook As Object, objSheet As Object
objApp = CreateObject("Excel.Application")
objBook = objApp.Workbooks.Open("C:maid2cleanM2CPrinters.xls")
objSheet = objBook.Worksheets.Item(1)

It's never been fast but in the last few weeks it seems to take forever.The "createobject" line is taking 4 seconds to run. is there any way I can find out why it's slowed down?
I am having a Friend Class InterceptingChannelBase class.It has a property as below:
Protected ReadOnly Property InnerChannel() As TChannel
Get
Return Me.innerChannelT
[code]....
This class is being inherited by (Friend Class InterceptingInputChannel) class which in turn contains another (Private Class TryReceiveAsyncResult) class.The property above is being used in this private class as below:
Public Sub New(ByVal channel As InterceptingInputChannel(Of TInputChannel), ByVal timeout As TimeSpan, ByVal callback As AsyncCallback, ByVal state As Object)
MyBase.New(channel, callback, state)
[code]....
I am getting the error on the above underlined statement saying that Protected Readonly Property InnerChannel is not accessible in this context because it is declared asa Protected.As far as i think,if i declare a property in class as 'Protected' then if this class is inherited by 'another' class then i can use this property and it should not throw an error.
Dim box As MultiTextBox = New MultiTextBox
Dim i As Integer
for i = 1 to 3 Step 1
lengthWidthHeight = MultiTextBox.GetItemValues()
Next i
This excerpt of code is using the NXOpen API. In the NXOpen API, the MultiTextBox class is public. However, when I compile the code I get the message:
'NXOpen.UIStyler.MultiTextBox.Protected Sub New(ptr As System.IntPtr)' is not accessible >in this context because it is 'Protected'
My question is, how am I getting an error about protected scope? Could it also be that the API documentation is incorrect?

I want to create an application that can run in both GUI and CLI mode. Basically what I want is when a user double clicks an EXE they get the GUI but when they run it through a command prompt they can supply CLI arguments and run entirely in the command prompt. I know that VBScript has the difference between Wscript and Cscript, but I don't know how to do that in VB.

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

{"Collection was modified; enumeration operation might not execute."}
The error flags up on the "Next" line in "ThreadedPing"

View 16 RepliesI'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.
