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?
View 8 RepliesWell my problem is so far the favicon shows up. But some sites don't have one and what i want is for a picture box to become visible when that happens.But i can't get the code to work (i suck at coding no surprise there).[code]Problem is it doesnt work. What happens on sites that dont have a favicon is that the last favicon loaded is the favicon of that site without a favicon.

I found this code but it's for non-tabbed webbrowser.How would you change it to work for a Tabbed Webbrowser?[code]...
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]
View 1 RepliesI've got a webbrowser. It's prettey advanced, given that I've spent quite a lot of time coding it, and here is my code which will get the Favicon of the current website when a the webbrowser has finished navigating:
frmBrowser.BrowserTabs.SelectedTab.Icon = Controller.GetFavicon(Me.Url.Host & "/favicon.ico")
Sometimes, a user has switched tabs before the webbrowser has finished navigating. So my question is: Is there any way in which I can determine what tab the favicon belongs to and set it to that tab, rather than just setting the favicon to the selected tab?
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 have a VB windows Form project that connects to several DataTables in an Access DB. On my form I have several textboxes, comboboxes and datetimepickers that are bound to those sources. With one table in particular when I try to update the tableadapter after editing one of the textboxes the update method fails. No exceptions are thrown, but the update method returns a zero value and the data is not updated. The update will work when just the comboboxes or datetimepickers are edited, but as soon as a textbox is edited also, update will not work.
Other DataTables within the project are set up in the same manner but are not having update issues. I can't figure out what about this one particular table is causing an issue. Can anyone give me any thoughts on where or what to troubleshoot?
I am currently trying to write a little wrapper around post-review to automatically post however this function fails when it comes to Dim results As String = sOut.ReadToEnd() and I can;t suss out why,
Edit: It doesn't produce an error it just seems to go into ReadToEnd() never to return
Function postReview() As String
Dim psi As ProcessStartInfo = New System.Diagnostics.ProcessStartInfo("cmd.exe")
psi.UseShellExecute = False
[code]....
Further Info: The actual command is working as I can see it posting to Review Board. But it just seems to get stuck in a loop while waiting on the Stream to complete. I have tried with Read and Readline with no luck?
I have a dropdown list that I am binding to a datatable. Here is the code I am using to do it:[code].....
Unfortunately, the line ddlBuildAddr.SelectedIndex = addressId is failing. Looking at this line through the debugger, the SelectedIndex goes to -1, while addressId goes to 2. What gives? Why would the assignment operator flatout not work?
My understanding of assert.fail was that if the line is executed, the test will fail.owever, I have found an instance where the assert.fail is executed, but the test passes.If the Assert.Fail statement is within a try block, the test will ALWAYS pass, even if the code execution executes the assert.fail. For example, the following test will always pass, even if the sub fails to throw an exception.

I am working on a mdi project and I have a few different xml files that I need to read in and I would really like to use multiple datatables, but only one dataset. I have always struggled to get a datatable.readxml(filename) call to work without an invalidoperationexception b/c of the schema stuff. I don't understand it very well and in the past my workaround was just to make another dataset. I am trying to avoid doing that from now on. I have written a routine called readxml which will take a xml file name, xml schema file name, and a datatable name and return to you a populated datatable..but I can't get it to work.
Here is my call to the read xml method (comes from my main mdi form class during form load)
Dim dt As DataTable = globals.xml.readxml("SqlConnectionString.xml", "SqlConnectionString.xsd", "sqlConnection")
Here is my readxml routine, I will post two versions of what I tried attempt #1: use a string of raw xml and a xmlreader

I do an dns test before i send mail to ensure i dont get errors.But there is a problem, when i try to send an email to an adress xxxxx@eco-log.sei get an error from the dns function. when i try to delete the "-" in the mail adress it works.at first i tohught it was because of the "-", but i made an email at zzzzzz@eh-design.se and it works like a charm, what could be the problem then? It is 100% sure that "xxxxx@eco-log.se" is an existing email/dns.The error message im getting is "No such known source"(freely translated)
Heres the dns check code:
Public Function testDNS(ByVal dnsstring As String) As Boolean
Dim email As String = dnsstring
Dim host As String() = email.Split("@")

View 2 RepliesI have an application that requires several threads, otherwise the main UI thread would end up frozen.i am after a little advice as i have not really don alot of threaded applications.
First Question;
I have a thread which handles data coming in from the serial port( this wil become much more complicated), is it safe to use a synclock on the serialport object : -

Unless the person actually gets into the source code they can't get the password am I right? Is it actually possible for them to get into the source code.
Basically what I'm asking is, is this safe and if not why not and how can it be made secure?
I'm calling a c++ dll I made myself - and it appears to be very VERY not thread safe!
I'm referencing it like this
<System.Runtime.InteropServices.DllImport("D:ACS DesktopdcxdcxDebugStringLibrary.dll", EntryPoint:="firstIndexOfKeyword", CallingConvention:=Runtime.InteropServices.CallingConvention.Cdecl)> _
Public Shared Function firstIndexOfKeyword(ByVal s As String, ByVal substr As String(), ByVal substrLength As Integer, ByVal markers As Integer()) As Integer End Function
Is there a way to make this IMPORT create something more threadsafe?

I'm dropping into this function - from several threads - to add an OBJECT to a dictionary collection
Private Delegate Function ReaderRegisterDelegate(ByRef rrFSOb As FSObject) As FSObject
Private Function ReaderRegister(ByRef rrFSOb As FSObject) As FSObject
Try[code].....
It's getting Object reference not set to an instance of an object.The FILEID key being added is F1. F2, F3 and F4 are in the dictionary. Seems like F1 arrived and the object wasn't properly setup. Or thread-slice caused me to see a partially messed with dictionary list?How can I make that a thread safe operation? I thought dropping out to the UI thread was a safe place to mess with code like this? Oddly enough I can go to the immediate window and do this
m_FSObCollection.Add("F" + rrFSOb.FileId.ToString, rrFSOb)
?m_FSObCollection.Count 4
ex.data is a dictionary list that looks like this
directcast(ex.Data , System.Collections.IDictionary).Count 0

Question: I'm looking up the account name and SID for each WellKnownSidType enum member as shown below.
Why does it fail sometimes?And why does it sometimes fail in converting the WellKnownSidType to a sid?As far as I understand it, only the conversion from sid to accountname should sometimes fail, and even that only when the account isn't local and not in the domain.
For example, when translating the enum LogonIdsSid to a SID, i get:
Bekannte SIDs des Typs LogonIdsSid können nicht erstellt werden.
(Known SIDs of type LogonIdsSid cannot be created.)
