  • parsing xml attribute value

    - by vbNewbie
    I have been parsing xml content using the xmlreader and cannot use the xml document but so far it works getting all elementcontent except for the attribute contents. I need to parse the link below found in the following entry; <title>XXXX UUUUUU posted a</title> <category term="NotePosted" label="Note Posted"/> <link rel="alternate" type="html" href="http://www.dfsddsfdsf.com/profile.php?id=sdfdfsfdsdfddfsfd&amp;v=wall&amp;story_dbid=dssdfasdfdasfdsafafafa"/> <source>......... <source> I need the href tag in the link attribute but it keeps coming back null. While ureader.Read If ureader.HasAttributes Then fId = ureader.GetAttribute("href") If fId.Contains("?v=wall&amp") Then fIdList.Add(fId) Exit While End If If String.IsNullOrEmpty(fId) Then fId = "NOTHING" End If End If End While

  • How is this inupt tag linking to another page?

    - by Matt
    Response.Write("<div><input type='submit' name='submit' value='Update Cart' /></div>") Response.Write("<div><input type='submit' name='submit' value='Shop More' /></div>") Response.Write("<div><input type='submit' name='submit' value='Checkout' /></div>") that is some example code from my teacher, but he hasn't answered my email in a couple days so I need some help. When you click the Update Cart button it just updates the cart page it's on, but when you click the Shop More button it links to Shop.aspx a different page, and the Checkout links to another page as well. I can't figure out how it is linking just from that code, anybody have any insights?

  • How to make Event visible?

    - by eflles
    Inside a Silverlight library project I have a public event, which is not visible for other classes. How can I make the event visible?

  • Managing tabs and their effects.

    - by VBeginner
    I have two separate areas in my form. Left side for radio buttons, combo boxes, etc. Right side for tabs and even tabs within tabs. For each tab selected, I'd like to display different controls on the left side for use in that tab. I've tried using many things, including focus, click, etc. Nothing seems to work the way I intend it to. Especially on the tabs within the tabs. Thank you.

  • How do you Bind to a ComboBox in a DataTemplate?

    - by discwiz
    I have a listbox that is bound to an observable collection of Audio (custom class). The Audio class has two properties, DisplayText (string) and a property called TarpIds (Observable Collection of Integer). I need to allow the user to change the TarpID in the combo box for each list item displayed and catch the selection change. I created a DataTemplate that styles the DisplayText property from the Audio object and adds a ComboBox to display the available TarpIDs for this audio (These are dynamic and unique to each Audio). The DisplayText works great, but I can not get the TarpIDs to display in the ComboBox. Here is what I have so far and thanks for any help. FYI I set the ItemSource at run time that binds the ListUploadAudio to the Observable Collection of Audio. <Border BorderBrush="Red" Background="WhiteSmoke" CornerRadius="8"> <Border.Resources> <DataTemplate x:Key="UploadLayout" DataType="Audio"> <StackPanel Orientation="Vertical"> <TextBlock Text="{Binding Path=DisplayText}" FontWeight="Bold" Foreground="Blue"> </TextBlock> <ComboBox x:Name="ListBoxTarpIDs" ItemsSource="{Binding Path=TarpIds}"> </ComboBox> </StackPanel> </DataTemplate> </Border.Resources> <ListBox x:Name="ListUploadAudio" BorderBrush="Transparent" Background="Transparent" Width="230" Margin="10" Height="200" IsSynchronizedWithCurrentItem="True" SelectionMode="Multiple" ItemTemplate="{DynamicResource UploadLayout}"> </ListBox> </Border>

  • Ways to make your WCF services compatible with non-.NET consumers

    - by Mayo
    I'm working on adding a WCF services layer to my existing .NET application. This layer will be hosted in IIS and will be consumed by a variety of UIs, at least one of which will not use Microsoft technologies. I can make a Web service in WCF that is consumed by my .NET application. However, I'm concerned about things that work in the .NET world but not with other technologies. For example, simply throwing an exception from my WCF service works fine in .NET. But according to this article, one should approach exception handling with fault contracts to ensure compatibility with non-.NET consumers. The author labels this lack of foresight as The Fallacy of the .NET-Only World. Does anyone have any high level suggestions or links to articles that cover interoperability between WCF and non-.NET consumers? I realize I'm potentially working against the YAGNI principle. I'm only really looking to avoid things that will be incredibly difficult to overcome later when the developers of the non-.NET consumer report problems to me.

  • How to break whenever any line of code executes

    - by Aequitarum Custos
    I have a very strange bug, which I believe is caused by some code we have executing, but I'm not sure where. We can reproduce it to the point it happens whenever we click Tab, but short of putting a break point at the beginning of every method in the project to find out what is executing. Is there a way to set visual studio to break whenever anything executes? For those curious about the problem, every now and then, we have a few Rich Text Boxes that refuse to lose focus. You can't click out of it or tab out of it. We have no On Validation or On Text Changed events attached to the control, and believe it's an event attached somewhere else to something we just aren't noticing.

  • Intercepting mouse events using a global hook. Stop an action from happening.

    - by fMinkel
    I'm attempting to intercept and interrupt mouse events. Lets say I wanted to disable the right mouse button down event, or even the mouse move event. I haven't been able to figure out the interrupting part. I am using the (I assume pretty widely used) following code for Global Hooking of the mouse. Private Structure MSLLHOOKSTRUCT Public pt As Point Public mouseData As Int32 Public flags As Int32 Public time As Int32 Public extra As IntPtr End Structure Private _mouseHook As IntPtr Private Const WH_MOUSE_LL As Int32 = 14 Private Delegate Function MouseHookDelegate(ByVal nCode As Int32, ByVal wParam As IntPtr, ByRef lParam As MSLLHOOKSTRUCT) As Int32 <MarshalAs(UnmanagedType.FunctionPtr)> Private _mouseProc As MouseHookDelegate Private Declare Function SetWindowsHookExW Lib "user32.dll" (ByVal idHook As Int32, ByVal HookProc As MouseHookDelegate, ByVal hInstance As IntPtr, ByVal wParam As Int32) As IntPtr Private Declare Function UnhookWindowsHookEx Lib "user32.dll" (ByVal hook As IntPtr) As Boolean Private Declare Function CallNextHookEx Lib "user32.dll" (ByVal idHook As Int32, ByVal nCode As Int32, ByVal wParam As IntPtr, ByRef lParam As MSLLHOOKSTRUCT) As Int32 Private Declare Function GetCurrentThreadId Lib "kernel32.dll" () As Integer Private Declare Function GetModuleHandleW Lib "kernel32.dll" (ByVal fakezero As IntPtr) As IntPtr Public Function HookMouse() As Boolean Debug.Print("Mouse Hooked") If _mouseHook = IntPtr.Zero Then _mouseProc = New MouseHookDelegate(AddressOf MouseHookProc) _mouseHook = SetWindowsHookExW(WH_MOUSE_LL, _mouseProc, GetModuleHandleW(IntPtr.Zero), 0) End If Return _mouseHook <> IntPtr.Zero End Function Public Sub UnHookMouse() Debug.Print("Mouse UnHooked") If _mouseHook = IntPtr.Zero Then Return UnhookWindowsHookEx(_mouseHook) _mouseHook = IntPtr.Zero End Sub Private Function MouseHookProc(ByVal nCode As Int32, ByVal wParam As IntPtr, ByRef lParam As MSLLHOOKSTRUCT) As Int32 'Debug.Print("Message = {0}, x={1}, y={2}", wParam.ToInt32, lParam.pt.X, lParam.pt.Y) If wParam.ToInt32 = 513 Then '''interrupt the left mouse button event here, but don't know what to return to do so.

  • Creating Modules for VB Program (Similar to firefox add on)

    - by Assimilater
    Hi all. I have a contact manager program that I'd like to design for multiple network marketing companies. My desired structure would include a core program which covers basic contact management functions. After that one could purchase a module for their specific network marketing company. This module would contain a variety of controls that the original program would need to be able to manipulate. Here is an example of what it would have to have: A group box containing buttons that link to a genealogy view, and the option to import one's donwnline from the back office provided by a company. A panel which is displayed on the contact page allowing the user to input business information or which will be filled by importing a downline from the back office: ie business ID, qualification level, sponsor information etc. a panel displayed when one searches for contacts on the contact list page which allows the user to sort based on information such as when they joined, what their business id is and so forth. a panel which is displayed in a personal business overview page which presents to an individual how many people in their downline are at each qualification level and develop a mailing list for individuals of a certain qualification level. I have the code developed to perform all these functions, I just wanted to give you an example of what needed to be done. I'm thinking that what I'm trying to create is a library that one can download and the program will recognize, but I'm not really sure where to go. What I'm really trying to do is figure out what kind of file I can make that will contain all this code and the GUI information that the program will recognize. Any ideas? With thanks, John

  • How to send data from an opened window back to its opener in WPF.

    - by TravisPUK
    In WPF I have one window opening a second window that allows some data selections to occur on. Once the selections have been made I then want to submit/close the second/sub window and have the data pushed back to the opening/parent window. I can push data into the sub window from the parent via public properties, but have not worked out how to get it back the other way. Can anyone help please? The code I am using to open the window and set some properties is has follows: Dim wdwContacts As New appContacts() wdwContacts.selClientID = selClientID wdwContacts.selEmailToCCType = selEmailToCCType wdwContacts.pullToAddresses = txEmailTo.Text wdwContacts.pullCCAddresses = txEmailCC.Text wdwContacts.Owner = Me wdwContacts.WindowStartupLocation = Windows.WindowStartupLocation.CenterOwner wdwContacts.Show() The basis is that I have the first window as an email composition page that has a button that when clicked brings up a list of email contacts. It brings through any previously selected email addresses from the first window and auto selects them on the sub window/email list. If further selections are made on the email list, when the op clicks the done/submit/close button it pushes the new selection list back into the relevant TextBox on the first/parent window. Thanks

  • Can I change properties of inherited controls at design time?

    - by Jeff Stock
    I am using visual inheritance and was wondering if there is a way to change the properties of inherited controls at design time, preferably in the form designer. If not, then in the designer code. I have my control declared as Public in the base class. I can access it in the child form code, but not in the form designer. Is this just not possible?
