I seriously doubt anyone has used that in VB6, or any VB for that matter. Why would you want to stop executable code from loading? You do realize that when your callback is called, the image is already loaded but has not started execution yet. You can't use the callback to stop an image from being loaded or executed. It's just used to notify your code that an executable image was loaded and is about to start.

What, exactly, are you looking at stopping?

Is there any way to intercept an image and be able to stop it. I am writing a security application and I am using the registry to stop applications running. By adding a gate in the HKCR\exefile\shell\run\command key I have successfully been able to block applications but the main problem is when an application is not loaded using the ShellExecute API i.e. it is loaded using the Shell("") command in VB instead. Do you have any ideas? Or are you going to tell me it can't be done based from your own knowledge?

VB.NET and Outlook's "BeforeItemPaste" Event signature

I am trying to respond to Outlook's "BeforeItemPaste" event. However, I am being notified by visual studio that the calling signature is wrong.

I think this is because the event's signature includes the param "clipboardcontent as Variant". Obviously VB.NET no longer supports a Variant data type. I have tried Object and VariantType, to no avail. How do I work around this? Thanks for the help.

.................
Dim WithEvents olExplorer As Outlook.Explorer

Private Sub olExplorer_BeforeItemPaste(ByVal ClipboardContent As VariantType, ByVal Target As Outlook.MAPIFolder, ByVal Cancel As Boolean) Handles olExplorer.BeforeItemPaste

MsgBox("got it! ")
Cancel = True

End Sub

Hello EveryBody
I implemented one ActiveX Control in Visual Basic 6.0. And I want to add instances of this control (Dynamically) in new control or new form. But VB is not allowing me to Set object to ActiveX control. (it allow to declare object but problem is in set operation). Eek! | :eek:

...every suggtion and help is regreated..

You might want to post the code your using so we can see what's going on. Adding the control is as easy as Dim myControl As New myActiveXControl and then adding it to the Form's controls collection.

Here try this it should allow you to create infinate instances of and object using a dynamic array... (First of all set the index property of your ActiveX object to 0)
{

Private Sub CreateNewActiveXObjectInstance()<br />
<br />
    Load ActiveXObject(ActiveXObject.UBound + 1)<br />
    'Object Upper-Boundary increases by 1 now<br />
    <br />
    ActiveXObject(ActiveXObject.UBound) = ActiveXObject(ActiveXObject.UBound - 1)<br />
    'If the previous line gives you an ERROOOOOORRRRRGH! then try setting<br />
    'the properties of the new object, bearing in mind you have just created<br />
    'a new instance in memory, all of its property values will be empty.<br />
    <br />
    'e.g.<br />
    ActiveXObject (ActiveXObject.UBound).[Property] = [Value]<br />
<br />
End Sub

Call this routine everytime you want to create a new instance of the object Smile | :)

For using dll in the another project you have two ways:

One way is to add ur dll project in the client vb project and make references Project -> References. In the references window it will show you the dll project's name select that name and say ok. Now you can use your dll in your client project.

--Or--

Make the dll of your dll project. By making the dll vb6 automatically registers it on your system. If you want to use or deploy it on another computer you need to explicitly register it using regsvr32.exe. Then open your client project Goto Project -> References in the references window look for your dll name and select it and click on ok. Now you can use your dll in the client project.

The former is best way to debug your dll project from the client project.

Interface Question

Are interfaces disposed when the go out of scope? Are the dispose methods of objects implementing the interface called when the interface goes out of scope?

No, because there is really nothing to dispose. An interface is an implementation that a class must follow and the class disposes any resources it has to. The interface declaration itself doesn't go out of scope. An interface is essentially saying, "This is the framework your class must implement."

hello
i have this problem with auto generation number via using function
the coding below is converted from vb6 and it is working in vb6
Public Function autoorderno() As String

Dim orderno As String
    Dim ordering As New Class1
    Dim order As New ADODB.Recordset
        order.Open "SELECT * FROM orders", cn, adOpenDynamic, adLockOptimistic, adCmdText
            auto = "000000"
                Do While Not order.EOF
                        order.Find "orderno ='Ord" & auto & "'"
                    If Not order.EOF Then
                        auto = Format(Str(Val(Mid$(auto, 5) + 1)), "000000")
                    Else
                        autoorderno = "Ord" + auto
                            Exit Function
                    End If
                Loop
                    autoorderno = "Ord" + auto
            Set order = Nothing
End Function

but some how in vb.net it say "value cannot be generated"
may i know what is wrong with the coding

Where does this message come from? It will not be generated by the code you posted, which is VB6 code, not VB.NET...

There is nothing wrong with this code other than it is not very effecient. Order numbers should never be reused, even if they have been deleted. This code will find holes in the order number sequence and re-use them. The detabase should have been written to generate ID's itself.

There is no one article that will do what you want. Your requirements are a combination of a bunch of smaller techniques that need to be put together correctly.

What's with the "random" order number? I've never seen a requirement where the order number must be random. I've only seen "serial number" type order numbers.

How I've seen it done in the past, and I've done this myself, is to have a seperate table in the database that holds your databases status and statistics, such as the last used order number. Your code would call a stored procedure in the database that retrieves the last used order number, increments it, stores it back in the table and creates a blank order record in the "orders" table, using the newly created order number. Then this record is sent back to your program as a dataset (SELECT statement). Your app then fills in the details of the order and writes back the order record, without having to worry about the order number at all.

Just to store it? You can't. That's not what this site is about.

If your sending your code to another person on the board, you can't. You'll have to put the .ZIP file for your project where someone else can get to it and then post the link to the download.

CE VB.Net Owner Drawn ListBox

Greetings to all,

I am in need of some sample code. I've just been thrown into the CE development arena and need to write an Owner Drawn ListBox Control that will run under CE. It needs to display different fonts, fontcolor, and background colors on a line by line basis. I've not done this before and need a place to start. Any suggestions would be appreciated.

Issues with owner drawing in the .NET Compact Framework would be better handled in the Embedded/Mobile forum. There are considerable differences between the two frameworks to justify having a forum just for mobile development.

A complicated string...

Brad Fackrell13-Jul-04 10:11

13-Jul-04 10:11

So much for figuring this out on my own Hmmm | :|

I’m trying to change the following string:

C:\this\directory\is\always\different

To:

C:\this\directory\is\the\new\one

I wanted to do this:

filePath = “C:\this\directory\is\always\different”

newFilePath = filePath.Replace(“is*”, “\is\the\new\one”)

Notice that I’m trying to use * as a wild card to include everything to the right of ‘is’. I don’t think its working.

'Is' – is always the same but filePath can be different each time the application is run. The only constant is the word 'is'. What I would like to do is find ‘is’ chop ‘is’ and everything to the right of 'is' and then add the new string, including ‘is’, to “C:\this\directory\”.

Did I say 'is'... Roll eyes | :rolleyes:

Brad

Re: A complicated string...

Dave Kreskowiak13-Jul-04 12:19

13-Jul-04 12:19

There is no wildcard support in the .Replace() method. All you have to do is find the directory "\is\" using the .SubString() method. THis will tell you the legth of the string to need to start with, then you can append the new path to the beginning of the starting path.

Dim filePath As String = "C:\this\directory\is\always\different"
Dim newFilePath As String = filePath.SubString(1, filePath.InstanceOf("\is\")
newFilePath = Path.Combine(newFilePath, "\is\the\new\one")

You can only do that if the Word document you are talking about is saved in .RTF format. If it's still in it's .DOC format, the RichTextBox will not display it properly. In that case, you'll have to either Shell launch the document so Word will open a display it or use the Word Object Library to open the document and display it.

If you are using VB6 you can use the web browser control instead of rich text box. This will display it as a word doc and even allow edits\saves etc. Dont know if VB.net does this though.
