I have been trying to use vb2008 to automatically update CustomDocumentProperties fields that I have set up within a pro-forma document. I can load the Word application and word document without problems.I want to update the CustomDocumentProperties fields with data read from a dB. To do this I am assuming that I need to iterate through the CustomDocumentProperties fields within the word document and when one is "found" that matches the data I wish to merge then assign the dB value to the field.The problem is that I am getting an exception error when I try to reference the document customdocumentproperties
"Error : Unable to cast the COM object of type 'System._ComObject' to interface type 'Microsoft.Office.Interop.Word.CustomProperties'. ...... "
my code looks like;
Dim WordApp As Word._Application
Dim odoc As Word._Document
Dim BContinue As Boolean = True
[code].....
We have currently upgraded our development machines to Windows 7 and Office 2007. We have a vb 2008 app that references 2003 Office components to use for mail-merging to word.We loaded up our app in the vb environment today and were instantly greeted with missing components/functions which are related to the 2003 Office components. We can update these to use the Office 2007 components/functions instead, however we are unsure whether after doing this our vb app will work with machines only with Office 2003 on. can machines with Office 2003 on work with our vb app that references Office 2007 components?
View 5 Repliesi was wondering if someone could give me the final explanation on what i might be doing wrong here.I spent a lot of time reading around the net and the forum about how to add Threading capabilities to a VB project.
Nos, i've got .NET 4 installed, and i've added the system.tsr and mscorlib.dll files as reference in, say, Excel 2007 (see screenshot).However, when i try to make a thread with anything as basic as "Dim Thread1 As System.Threading.Thread", i get a user-defined type not found error.Indeed, when i use the object browser to see what's in the System file, theres nothing remotely linked to any Threading, and in the mscorlib file, nothing under "Threading" either, just a few Thread related functions, but nothing defining a data type
I've developed shared addin for Microsoft Word. I distribute this addin with my application and using Inno setup for installation. The Inno setup installs my application and then runs "myAddin.msi" file in order to install addin.
how to uninstall this addin programatically?
Right now, in order to uninstall addin, the user has to to it manually through control panel.

View 1 RepliesI've made Add-in for Word 2007 in VS2005.It worked well with Word 2007 and now it works well with Word 2010 32 bit.However it doesn't work with Word 2010 64 bit. The installation is successful, but the ribbon button doesn't show up.
Do you have any experience with add-ins for Office 64 bit?
I have used VB.NET and Microsoft Offices Interop to create an application that will run on a server and will print files for different users.My problem is that I need to find a way to impersonate different users so that when MS Word opens and prints, the resulting print job is recorded under that user. I found this link that lets you run .net code as a different user - unfortunately it doesn't work with this code. The username recorded is still the user that is logged on the server.Code Removed by moderator. Any ideas how I can make the Office app I'm automating run under a different user to the .net program that is calling it?

So I'm guessing it has something to do with the fact that I don't have office loaded on my computer. Now I have another laptop, with office that I loaded this project on, and it works fine. So do I have to load office on this computer, or can I just reference something?

How to simplify this, 2 method in class are identical.First class.
Public Class Gui
Inherits System.Web.UI.Page
Public Sub CreateStyleLink(ByVal StyleArray() As String)
[code].....
I have classes setup similar to this:
<DataContract()> _
Public MustInherit Class SystemTaskProcessBase
Public MustOverride ReadOnly Property Name() As String
Public MustOverride ReadOnly Property Description() As String
Public MustOverride Property Result() As SystemTaskResult
[Code]...
I need to use these classes on the client system, but also need to be able to create these "tasks" through a management interface. Each class (Task) that inherits the base, could have its own properties that are unique to each class, but at the same time, share the same common base class properties. For example, the above shows a reboot task and a delete file task, the delete file task needs to know which file to delete, so has a property for that. But the reboot task does not need this property. So when the management application is creating these tasks, it shouldn't provide a text box for the file property for the reboot task. There may be more tasks created at a later date with completely different properties.
How would I go about providing the WinForms management application a way to enumerate each class into a ListView for example, and allowing the user to create these tasks and filling in the dynamic properties that each class would have? Desired functionality would be to create a task form that creates dynamic controls available for the properties as needed, depending on the public properties in each class, but at the same time have the base class properties available as well.
In the code below I recieve the compile error "Error Too many arguments to 'Public Sub New()'" on the "Dim TestChild As ChildClass = New ChildClass("c")". I do not recieve it on "TestChild.Method1()" even though they are both on the base class I am inheriting from.
Public Class BaseClass
Public ReadOnly Text As String
Public Sub New(ByVal SetText As String)[code].....
As suggested below but I do not have to do that for Method 1 or other inherited methods and I am looking for the cleanest code possible. This may be a limitation in the system with inheriting parameterized New statements but I can not find it documented anywhere. If it is required then I would like to see the documentation.
I would like to inherit a UserControl I created.I use to C#, is this possible in Visual Basic? [code]The error I am getting is on the inherit BaseObject: Base class 'BaseObject' specified for class 'BaseLeftObject' cannot be different from the base class 'System. Windows.Forms.UserControl' of one of its other partial types.

View 4 RepliesI have a project, let's call it "BASE", that has a bunch of .CSV files as Resources. The project makes references to My.Resources.XXXXXXX in different methods where XXXXXXX is the CSV filename. I am working on a class that derives from "BASE" and I would like to change some of the .CSV files and replace the ones that are in the "BASE" project with mine. I would like the methods in the base project to use my CSV files when it calls My. Resources. XXXXXX instead of the files that are in "BASE"'s Resources. Any tips on how to do it? (any .NET language is welcome)
View 1 RepliesI have the following sample code in a VB.NET console application. It compiles and works, but feels like a hack. Is there a way to define EmptyChild so that it inherits from Intermediate(Of T As Class) without using the dummy EmptyClass?
Module Module1
Sub Main()
Dim Child1 = New RealChild()[code].....
The other way to do this would be to move the generic code out of the Base class and then create 2 Intermediate classes like this [code]...
Then RealChild would inherit from the generic Intermediate and EmptyChild would inherit from the non-generic Intermediate. My problem with that solution is that the Base class is in a separate assembly and I need to keep the code that handles the generic type in that assembly. And there is functionality in the Intermediate class that does not belong in the assembly with the Base class.
i'm working with different classes and different constructors. It's working fine until i try to inherit a class that also has a constructor. vb asks for mybase.new but when i add that vb says that a constructor cannot call itself, when i try it in a different way vb asks the parameters of the constructor of the class that i want to inherit.

Is this possible? Must be surely but I've tried and come up short. I've created a very basic class (person) with 2 public properties, forename, surname. My user control is databound to this class and has 2 textboxes to store the properties.
I've built the control and can add the user control to a windows form but how can I add to a new user control (Staff) which will show my 2 existing textboxes and I can add dateJoined datepicker also??
I'm in the process of creating my own version of the Combo Box as MS version does not give me the flexibility I need, this is work fine. I just had a little niggle
The List box contains/uses ObjectCollection to hold all its objects, but it does not have the facility to inform by the way of events that an item has been added etc.
If I inherited from this collection could I add the necessary code to make this happen, I have done this in my previous controls I�ve created when I wanted this facility.
I use visual basic 2008, I use Groupbox1, In the Groupbox1 in have two labels: label1 and label2. I have change the font of label1 with properties to size 12, No i change the font size of Groupbox1 with properties to size 8, Only label2 inherit font (8) format from GroupBox1 and label1 inherit not font change. I want that label1 and label2 inherit font from GroupBox1, always! I how can i do this?
