VS 2008 Invalid Parameter Error When Trying To Get Favicon In Stream
Aug 24, 2009
I am using VB.Net 2008 Express and trying to build a favorites list for a webbrowser I am working on.I get an invalid parameter error on the line that reads favicon = image.FromStream(stream).[code]the urls are stored in an array after they are taken from an xml file.I checked the url that was being used when the error occurs and it seems fine. I can even navigate to it in IE.The error I get is that "stream" is an invalid parameter, at least that is where it points to.It also shows that stream is a type System.NET.ConnectStream.Stream was originally set to System.IO.Stream.I don't know if this is a problem but it processes several urls before it gets to this one.I am wondering if this may be a permissions issue and the site is blocking the WebRequest or if it is something else.
I am running the same program on two workstations. One reveals no errors while the other shows a "COM exception error: invalid parameter." The offending line of code is shown below.Is there an explanation for the inconsistency?

I'm making a tabbed browser and I want to get favicons in the tabs. I have a picturebox by the address bar that shows it just fine, but I want it in the tabs also. The tabs are owner drawn. Can I use the image key to display the favicon? If so, how? I've tried drawing the image in, but it draws it to every tab instead of just the one. Is there any way around this?
Me.PictureBox1.Image.Save(memStream, System.Drawing.Imaging.ImageFormat.Jpeg) Dim imSource() As Byte = memStream.GetBuffer Dim imStatus As Integer = publicStream.Read(imSource, 0, streamLength - 1) imSource.GetValue(memStream.ReadByte)

I am creating a web browser just for fun and am trying to show the favicon. If you dont know what the favicon is it is the little icon that you see next to the url when you go to sites like [URL]

When i execute the code i get an error "Invalid Parameter : Name handle" in the line outFile = New FileStream(_SafeFileHandle, FileAccess.Write) . As this is a USB port So i shared the printer and used the UNC path. But still i get the error. Below is the complete code

UploadData(Username as string, Pwd as string, XMLdata as String)The XMLData will be xml data 2-5mb.Is String the best data type?I've tried the stream datatype and that does not work as a parameter on a webservice.
I have created a windows Service which invokes executables on remote machines, waits for it to complete and then proceeds to the next machine on the network.
The Account type for the windows Service is "Network Service". For monitoring if the process is completed on the remote machine, I am using ManagementEventWatcher class. I get the following error when I start the Management event watcher object.
I'm using WMI code and VB 2008 to see NIC status. So far the queries are working, but the methods aren't. For example, I'm trying to set a network card to use DHCP, I get invalid function with this code:
Dim classInstance As New ManagementObject("rootCIMV2", "Win32_NetworkAdapterConfiguration.Index='7'", Nothing) Dim outParams As ManagementBaseObject = classInstance.InvokeMethod("EnableDHCP", Nothing, Nothing)
Here is my problem: I developed one application in VB.Net in VS 2008 Express Edition on MS Vista. I published the application and created the installation setup. Now when I install this application on any Vista machine, it runs without any problems, but if I install it on an XP machine, the installation is clean, but when I launch the application, it ends abruptly without any warnings/error just after the splash screen.
Then to investigate further what I did was that I copied the source project from my VS 2008 Express Edition on Vista to an XP machine having full (VS 2008 Team System) version , and when I try to compile it there (XP/VS2008 Full), I get one error in one of the forms resx file. Incidently this is the same form that gets loaded after the splash screen. So I see there is some correlation between my application ending just after the splash screen and failing to compile the main form of the application. The error that I get reads like: "Invalid resx file. The parameter is incorrect Line 1374, position 5."
Following code doesnt work and raise error "A parameter is missing. [ Parameter ordinal = 1 ]".What s wrong with it?I am developing pocket pc application in vs 2008 and sqlce 3.5 sp1.
I am trying to write a small app that will read images from an database to an image list. It does the first one, but then after that i get a "Parameter is not valid." exception ... see code below.
vb Dim cn As New OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Application.StartupPath & "states.qmw") Dim cm As New OleDb.OleDbCommand("Select * from tblStates", cn) Dim rd As OleDb.OleDbDataReader
Visual Basic 2008 rookie question. I am getting the error message 'Error 1 The item "objDebugCIT163Lab1Cdrb.WeatherReport.resources" was specified more than once in the "Resources" parameter. Duplicate items are not supported by the "Resources" parameter.CIT163Lab1Cdrb'when I debug. I am familiar with Visual Studio 2008 having used it for my previous C# course. Zipped and attached the project below. I hadn't finished the coding, but this problem seems to be of a setup nature I should either resolve before I continue or start from scratch
I'm trying to decrypt some data but I get this error: Padding is invalid and cannot be removed. It highlights the _streamWriter.Close() line. This is the code I'm using to decrypt a file:
vb.net Imports System.Security.CryptographyImports System.TextImports System.IO Public Class EncryptFile Private Shared Buffer(4096) As Byte Private Shared _Rijndael As New RijndaelManaged Private Shared _Hash As New SHA256Managed Private Shared _Encoding As New UTF8Encoding Private Shared IV As Byte() = {12, 4, 58, 74, 52, 33, 69, 87, 47, 8, 23, 69, 85, 47, 85, 21} Private
[code]....
When I encrypt a file it gives me no error, but when I decrypt a file it gives me this error: Padding is invalid and cannot be removed. In this line:
vb.net cStream.Close()
I don't understand why, because I'm using the same IV and the same key, I've even checked the generated hash, and to me, it seems the same.
I want to have a "template" function that can receive different parameter and a type parameter, like:[code]But Vb told me that tupeList is not defined... is there a way I can do that?
However, I now have the problem when I loop the code string I get the following error: "Parameter '?PassVar' has already been defined.". I never had this problem before I upgraded.
