VB6 - Call A Function With CreateObject ( Type )?

Sep 1, 2010

I have a dll ( vb6 ) containing a public class with a public Type ( named Test ) and finally a public function that wants a variable passed by ref of Test type. Obiouvsly, if I reference that dll in a new project ( vb6 ) I can see the public function and the Test type I must use...the problem comes when I must call that dll creating it at runtime without any reference, using in example CreateObject. Can I reference in some way the type Test inside the dll by having created it at runtime? If I declare a type IDENTICAL to the Test type in a public class in my new project, VB issues a TypeMismatch error even if both data type are the designed the same say, have the same name and so on! how it comes?

Cannot Create ActiveX/CreateObject(). - Permissions?

Jun 30, 2011

I am troubleshooting a program that normally works, and has worked in the past on the machine I am working with.I am a very novice programmer, I didn't program this myself I am just trying to get it to work.I have done as much research as I can, which has lead me to believe it is permissions problem with the CreateObject command.I have tried a fix in the .net 2.0 machine.config file, changing the processModel user to System, that didn't help.The machine does have norton on it, and norton was installed since the program stopped working. However I have tried disabling norton and running the program. A friend suggested it might be some settings on the computer that Norton changed hence disabling it not helping.Here is the error:See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.[code]... When JIT debugging is enabled, any unhandled exception will be sent to the JIT debugger registered on the computer rather than be handled by this dialog box.

In .net, If A Function Returns An Object, Is It Wrong To Just Use The Function, _as_ An Object

Apr 30, 2009

I've got a f(x) that returns a collection of user controls. .Net lets me just treat the f(x) name as the collection.

ex)

Function - Pass Object Versus Reference Object In Parent?

Dec 1, 2011

I am working on a application that has quite a few functions involved and have been thinking of the following: If I have a function that has a few paramaters, is it more efficient to pass the objects to the function(Example 1) or reference the objects in the parent(Example 2)? Does it matter if the objects are large or not?

Example:

Class mainform
Public myGenericList As New List(Of String)
Public myDatarowArray() As DataRow

Updated. I'll see if I can update with the DataAccess.GetData code. I didn't originally put it in there because our shop use it all the time and have no issues with it.

Dynamically Change The Function Of A Delegate In .NET?

Jun 18, 2009

Suppose I have a class that represents a product to be priced using one of a number of different pricing strategies. This pricing occurs hundreds of times per second, so to eliminate repetitive if/else statements I am instead using a delegate to launch the appropriate strategy, like so:

Private Delegate Sub PricingModel(ByVal params As PricingParameters)
Private myPricingModel As PricingModel
Private myPricingParameters As PricingParameters[code].....

But this doesn't look right to me (though it seems to work). Is there an accepted/better way of doing this? Or is this the standard way? Or is this just simply a doomed approach from the start?

Dynamically Pass Values To An Object?

Mar 28, 2011

How can I do this:

Dim oMyObject As New MyObject
oMyObject.DoSomething("Parameter1","Parameter2")

The "DoSomething" and the two parameters are dynamically provided from another script. They are stored in a string object in this script: sAction & sParameters. My question is how can I dynamically pass the "sAction" to the object oMyObject.For example oMyObject.sAction (where sAction should be the value stored in the sAction string). The example will probably not work. Is there a way to do this? The idea behind is to avoid having to write each function hardcoded, like:

If sAction = "DoSomething" then
oMyObject.DoSomething(sParameters)
ElseIf sAction = "AnotherThing" then

Forms :: How To Call Unkown Function In Another Class Dynamically

Jan 20, 2012

I've created a dialog which I'd like to popup from any function or sub in any class or form that I have in a project. It would nice to have it work exactly like a messagebox except it's got a progressbar and a cancel button on it. It's job is to display the progress of other functions so it should just stay open until I close it or the user selects cancel.Now I've found many of the basic examples on the net and have got the dialog working exactly as they have shown it. The trouble is that the examples are using a counter or thread.sleep which simply adds +1 in the DoWork sub. In other words, it validates that a worker thread can update a progressbar but it's a closed loop that only exists in the dialog's class.The examples don't show how to call an unkown function in another class dynamically, they're simply a hard coded 1+1 in DoWork. To me it's not a real world example because it doesn't show how to plug into the dialog or get a communication stream from other classes and functions that are running and wanting to increment the progressbar.[code]

Stopwatch - Selecting The Most Recently Dynamically Created Object With .NET?

Feb 3, 2012

Below is some code that I'm using to create objects with Visual Basic:

For indexCounter As Integer = 1 To TotalParticipants Step 1
participantClock = New Label
participantClock.Size = New Size(100, 20)
participantClock.Name = "participantClock" & indexCounter

[code]....

I'm creating a label, a button, Timer, and Stopwatch. (Though I have sinking feeling I don't need BOTH a timer and stopwatch since I'm counting time.)What I would like to do, is create the label and set that label's text to be the value from the stopwatch. The button that will be created will stop THAT stopwatch.

The problem that I'm having is that I cannot call the stopwatch by name since it wasn't created yet and VB throws a hissy fit at me for it. (After all it wasn't really declared.)So the question becomes, how do you call the most recently dynamically created control and assign events using that control. If it's not possible to do, I do not mind dumping the form and starting over creating 30 stopwatches instead (but I'd like to avoid that, if possible).
