Why on Earth would anyone write a converter to convert modern code back to something used in the Stone Age??
No, there's no such thing.

Hello,
I am trying to write a VBscript that allows me to search the file names of every file in a folder and rename them accordingly. For example, I'd like to find all files that begin with RX345678 and replace that name with Bob & MMDD & counter & .txt The counter will allow for the multiple factor. I already have the code for the date, but, it's pulled from an old script and it's been forever since I wrote in VB so my naming is poor.
This is also in Visual Studio 2005 (yeah, I know!  )
Thanks for any advice!

Where is the code you already have, and where are you stuck? Should the serial-number reset after each date, or would you be satisfied with a single range?

Sub FormatDate
'Set datepart("yyyy",date()-1) & datepart("m",date()-1) & datepart("d",date()-1)
If len(datepart("m"))=1 Then
monthstr = "0" & datepart("m")
Else
monthstr = datepart("m")
End If
If len(datepart("d")=1 Then
daystr = "0" & datepart("d")
Else
daystr = datepart("d")
End If
objDatestr = datepart("yyyy") & monthstr & daystr
End Sub
Is the current date code. I'm stuck on the proper language to use in order to read the file name and rename it. What I am thinking I would like to have is a routine for each name that could occur. Max = 9. I don't know the number of files per name, so, that's why I was going to add the counter. In each routine, it would search for a specific name and turn that into what I expressed before. I know I sound stupid, but, I know how to code and I know what I want but, this got dumped into my lap and we have no resources here to assist me.
The counter will be set to 0 before each routine. (in my version).
Thanks for anything that points me in the right direction!

I suggest you start with a routine that lists all the files, and sorts them. Loop through them after that, reset your counter when the date changes.
Most code you'll need can be found here[^].

Thanks for the suggestion and the link. I checked it out but, not really sure I'm searching on the right things. Oh well, guess it's off to the book store for some blurry-eyed late nights.!

Hello,
I've developed a .net dll and made it com Visible and also i've added register for com interoperability.
I need this COM object in visual basic 6.0.
It works fine, when i build the .net component. It generates a .tlb file and i could get my result as expected.
But when i executed this on the other machine it shows error.
i've copied my dll to the other machine and generated a .tlb file by using 'regasm'.
I can see the tlb file in references of my Visual Basic 6, but it is giving error that "Could not load file or assembly 'thirdpartydll' or one of its dependencies".
i've tried by registering with GAC but could not solve my problem .
please help me !
Thanks,

Did you reference any other libraries in your control?

Which assemblies does your .net dll reference?

No. He meant did you have to add a reference to anything in your VB.NET code that you wrote this COM component in?
|
|
|
|
|
I did not add the references in vb6 application.
but my component has references in it.
do i need to add those references which are in my component ?

You do indeed. Anything used by your dotNet component must exist in any environment that you deploy the component to. Dependencies are not going to be compiled into your assemblies.
I wasn't, now I am, then I won't be anymore.
|
|
|
|

Not quite. Any unresolved references in the VB.NET COM component will NOT be resolved by adding a reference in the VB6 project using the component.
He's still stuck on adding references to his VB6 code to fix this, which we all know won't work.
|
|
|
|

Sorry. Maybe I wasn't clear enough. If the assemblies required by the COM-Interop assembly are available in either the install directory of the component that requires it or in the GAC, then his reference of the COM component through VB6 should work. I'm working from memory here as I haven't done anything like this in a couple of years.
I wasn't, now I am, then I won't be anymore.
|
|
|
|

Oh, no, you were clear. I'm just saying if the assemblies were present, he wouldn't be have the problem in the first place and hence wouldn't need to add references to them in his VB6 project.
|

Understood. I reread your response and that was clear. I just must have read it too quickly. Cheers.

That's probably why it's claiming that one of the dependencies cannot be found; your component references something that's not available (or registered!) on the target-machine.
VB6 isn't interested in what your component uses; but the things that the component uses "should" be available on the target-machine. The .NET runtime will then load them for you.

Thank you Eddy and Marcus Kramer..

Again, we're not talking about your VB6 code at all. All we're interested in is the VB.NET code you wrote to write this component.
If you added references in your VB.NET project to other libraries, you MUST copy those libraries over to the target machine at install time for your component. If your component code is using something in a library, how is the code going to work if the item referenced is not on the machine?? It'll throw the very error you're getting, specifically, the part about "or one of its dependencies".
You do NOT need to add any references in your VB6 code, other than the one to your COM component. Those references won't work for your component anyway. You DO need to make sure that everything your component uses is installed on the target machine.

Let's put things in other words, maybe you'll understand then.
You created a dll in .Net for COM interop, let's give it a name here: MyCOM.dll.
When you created MyCOM.dll, you referenced ThirdParty.dll. That means, MyCOM.dll depends on ThirdParty.dll to be available.
On your machine - where you developed MyCOM.dll - ThirdParty.dll is available.
But on the other machine, it is not.
How to solve: copy ThirdParty.dll into the same directory as MyCOM.dll.

As the subject states I am having some trouble with implementing a delegate to solve this issue that I am having.
The error that I am receiving is that cross-thread operation is not valid. I have windows form that we will call Form1 for example that has many buttons. For one those buttons opens up another form that we will call for this example Form2 that will display some data. Form2 has a COM obj that is similar to a datagridview, but it displays the data which is similar to a pdf viewer that can allowing zooming and formatting. Before I start posting where my problem is in code I did some searches and everyone suggests to use Delegates to prevent the cross-threading problem. I am quite new to delegates so I have been reading the MSDN Documentation[^] about delegates, but I am still not understanding it quite well. Also, I have read this great article A Beginner's Guide to Delegates[^] about 3 times. I understand it's a introduction article.
Here is snippet of code that is causing me problems while I am using delegates (incorrectly???)
Note: This snippet of code is from Form1
Public Delegate Sub StoreDetailedOutputID(ByVal strID As String)
Private strKey1 As String
Private Sub AnalysisResultsEngineName(ByVal strEngineName As String)
frmAnalysis_Results_Form.Set_Engine_Name(strEngineName)
End Sub
Private Sub cmdSpreadSheetOutput_Click(ByVal eventSender As System.Object, ByVal eventArgs As System.EventArgs) Handles cmdSpreadSheetOutput.Click
strKey1 = "Please work!"
Dim dEngineName As StoreDetailedOutputID
dEngineName = AddressOf AnalysisResultsEngineName
dEngineName.Invoke(strKey1)
End Sub
With that I have a few additional questions so that I may understand what delegates are all about.
-Where should the delegate be created within my program? Form1? Form2?
-Should the Delegates be created on both forms?
-Should I use BeginInvoke instead of Invoke?
-Is Delegates indeed the correct route to go? Should I use Threading?
Any help to clarify my misunderstanding of delegates would be greatly appreciated.

A Delegate is a method-pointer, you could look at it as an interface on a method-only-level. That means that it defines a Type, like an Integer, but not for data, but for methods. That means you can store a reference to a method.
When a single-threaded application is executed, it's the UI-thread or the main-thread that builds the controls. A thread executes the instructions in the code one after another. That's why you sometimes see a form go completely white when it is doing a lot of processing; the UI thread is too busy to do the drawing. To prevent that from happening, and have a responsive UI, we do the heavy work on a separate thread.
Clark Kent123 wrote: -Where should the delegate be created within my program? Form1? Form2?
On the place where you intend to call it, you'll need an instance. That instance could be passed using a parameter, as a Delegate is a Type that "acts" as a variable.
Clark Kent123 wrote: -Should the Delegates be created on both forms?
No, but the delegate is often public, so that it's Type can be used in other forms (from where it's called, for instance)
Clark Kent123 wrote: -Should I use BeginInvoke instead of Invoke?
Invoke should execute it on the same thread; that Exception you mention should only occur when you use BeginInvoke, as that creates a new thread. In that case you'll also need the Invoke-pattern[^].
Clark Kent123 wrote: -Is Delegates indeed the correct route to go? Should I use Threading?
You should be able to answer that by yourself now; threading is for heavy tasks, delegates are method-variables. Here's an example that uses both;
Imports System.Windows.Forms
Imports System.Threading
Public Delegate Sub MyCallbackProto(Count As Integer)
Public Class TheThreadClass: Inherits Object
Private mySomeCallbackRoutine As MyCallbackProto
Private myThread As Thread
Public Sub New(aSomeCallback As MyCallbackProto)
mySomeCallbackRoutine = aSomeCallback
myThread = New Thread(AddressOf Work)
myThread.Start
End Sub
Public Sub Work()
For i As Integer = 0 To 100
Thread.Sleep(50)
mySomeCallbackRoutine(i)
Next
Application.Exit
End Sub
End Class
Public Class Form1: Inherits Form
Private myProgressBar As New ProgressBar
Private myThread As TheThreadClass
Public Sub New()
Controls.Add(myProgressBar)
myThread = new TheThreadClass(AddressOf OnUpdate)
End Sub
Sub OnUpdate(Count As Integer)
myProgressBar.Value = Count
End Sub
End Class
Public Class MyApp
Public Shared Sub Main()
Application.Run(New Form1())
End Sub
End Class
Another cool intro to delegates is the A Beginner's Guide to Delegates[^] article. There is a series (5 articles I believe) on threads called Beginners Guide to Threading in .NET: Part 1 of n[^].
Enjoy

I appreciate that answer. Yeah, I do agree that by now I should be able to answer whether threading or Delegates is the way to go. I am going to stick with Delegates and take some time to digest all this information. As well as go reread all those delegate articles.
I am sure later on I will look back and think of how easy it was to set this up.
Thanks again.
