VS 2010 : Parameter Count Mismatch?
Jul 19, 2011Im trying to create a per user installation for my program made in vb.net I have .net 4 as a prerequisite which im going to download if its not installed The problem ive run into is admin rights is there a way to install the framework as an admin/elevated user then install my application as the current user so basically user launches bootstrapper -> pre-reqs run as admin -> application runs as current posibbly limted user.Im making the installer for my application using Wix (3.5), then im using dotNetInstaller to bootstrap and deal with the prerequisites.
If an admin installs application from the limited users profile he takes over the installation, which is what I dont want, but if the .net isnt installed the admin has to do this. The admin could install the pre-requesites then close the bootstrapper then the user could install the application but this doesn't seem like a great idea.

View 3 RepliesPossible To Instantiate And Invoke Delegate By Name?
Mar 5, 2009I'm trying to figure out if it is possible to instantiate and invoke a delegate by name, rather than explicitly. I think the code below explains it fairly well. I want to accept a function name and then instantiate the delegate based on that. In the example I use a select case, but I want to eliminate that and just use the methodName argument itself.
Private Delegate Sub myDelegate()
Private Sub myDelegate_Implementation1()
'Some code
End Sub
Private Sub myDelegate_Implementation2()

Why Isn't Invoke Via Delegate Built Into .NET
Sep 1, 2011I understand that .NET is multi-threaded and that is a good thing, but I continually run into issues when I have a background worker for example that is updating some control on my form and I have to do:[code] My question is why is this not built into the framework - surely if I am trying to update a DataGridView it should be intelligent enough to know when the update is from another thread and it could do all the above itself?
View 3 Replies.net - Control.Invoke Never Calls Delegate?
Oct 1, 2009I'm working with the DevExpress XtraGrid control.I have a routine that goes thru and adds all the controls on the current form dynamically, and launches on a seperate thread the routine for a given control to initialize it to the value that will be displayed to the end-user. Some of the controls are displaying calculated values, and take some time to return their values, so that's why we are doing it on a seperate thread.
[Code]...
I'm using a similar snippet of code for any control properties that have to be updated, and all work fine. On the above code when the actual Invoke is called, it APPEARS that the thread just ends and never calls the delegate, and doesn't return to finish either.
Method Invoke Use Delegate As Argument?
Aug 16, 2010I have some code in c#
BeginInvoke(new MethodInvoker( delegate() {myAppMethod_Tick(sender, e); }));
Now, When I tried to convert that code to vb.net I have below..
BeginInvoke(New MethodInvoker(Function() Do myAppMethod_Tick(sender, e) End Function))
But it does not compile.. What's problem for it?
Because my c# application works ok without any problem..

View 9 Replies.net - Call Winforms-style Invoke/Delegate From MVVM?
Oct 12, 2010I'm hacking away at some code which seems to have been started, at least in theory, as an MVVM project in Expression Blend, by my predecessor at this company.
I've got a thread running in the background, which is running some operations on items as they happen. In order to prevent any clashes, I've also got that thread running any operations my users call for.
Once those operations are completed, I'd like to bring up a MessageBox to give a summary of the user-initiated operations, but now that they're running off in their own thread, the finishedProcessing event handler is now running on the background thread instead of the interface thread and it's causing my MessageBoxes to appear non-modally.
Back in the WinForms days, I'd have handled that using InvokeRequired, Invoke and a Delegate. I've read that this has been replaced by something called "Dispatcher", but the ViewModel class I'm using doesn't seem to have a Dispatcher object.
The "thisViewModel" class I'm using inherits a class called "WorkspaceViewModel", which inherits "ViewModelBase", both of which look generated to me...
where I can link up to this "Dispatcher" from here?

VS 2008 Passing EventHandler Delegate As Parameter
Jan 13, 2010I have a Dialog Box that creates a Link Label for each item in a list.When one of those LinkLabels is clicked the DialogBox raises a LinkClicked event.Before, I was using code like this in the Form that was instantiating the Dialog:[code]But I don't like that for several reasons.What I want to do, and what I thought would be straight forward, was to pass the AddressOf the UserClicked PoLink Method into the ShowClickableLinksDialog Constructor and do an AddHandler within the constructor and also assign the Delegate to a Property on the Dialog so as to RemoveHandler when the Dialog is Disposed.[code]But I get a squiggly on the tempLinkClickedEventHandler after the AddressOf Operator saying: "AddressOf operand must be the name of a method (without parenthesis)"I don't get it.I've played around with a number of permutations and can't get what I feel ought to work, to work.

Multicast Delegate: Represents A Multicast Delegate; That Is, A Delegate That Can Have More Than One Element In Its Invocation List?
Jan 30, 2010from the documentation we have this: Multicast Delegate: Represents a multicast delegate; that is, a delegate that can have more than one element in its invocation list.
so am i right to say that Multicast delegate is no different from a normal delegate other than the fact that it has arguments. so System.Action is a 'normal' delegate whereas System.Action(T)(Byval obj as T) is a multicast delegate?

For Each Next Statement : Type Mismatch Error
Sep 10, 2010I have tried repeatedly to use a For Each Next statement inExcel 2003. The intent of this is to ititerate through a predefined selection of cells and set the value of the cell 3 columns to the right based on the value of the cell in the selection.
The latest code I have tried to use is the following:
SR.Range("a5").Activate
SR.Range("a5", ActiveCell.End(xlDown)).Select
Selection.Offset(0, 5).Select
[code]....
Where SR is the active sheet. (I have only been introduced to VBA and code language for a few weeks, so I am learning as fast as I can. Please excuse my ignorance!)When I get to the 'If x.value' line I get the type mismatch error. I have tried to set my "each" to variant variable types and my "collection" (or selection as it were) to different variable types and constantly I am getting this same error regardless of my efforts.
