There is no isAlphabetic function anywhere. You'll either have to write your own where the function will go through the string, character by character, and verify that it is an alphabetic character, or you could probably use a Regular Expression to verify that it is in the proper format. I'm far from an expert on Regular Expressions, so I don't know what the expression string would look like.

You have to write your own code. In my opinion you should write the code as the following concept.

1. Write the code in the KeyPress or KeyCode event to check whether the textbox is blank or not.
2. If the textbox is blank, then any letter between a to z have to plus with 32 (I mean the ascii code of that letter must pluse with 32, Roll eyes | :rolleyes:

maybe 32, try to check in the ascii code table). Then the small letter between a to z will display in capital letter A to Z.
3. If the textbox is not blank, then don't do anything.

Try to do it and wish you good luck.

msscript.ocx question...

I don't know if this is the right forum but I have a question about microsoft script control (msscript.ocx). I need to call scripts (VBS,JS...) from my app (C++ or whatever). I wonder if msscript.ocx is the right tool for that. Is there a more supported by Microsoft API for that?

They talk a lot about Scripting host but in terms of writing the scripts, not how to call them.

Thanks a lot!

Hi all,

I use DDE with API and it runs fine with texts. Now I need to "transfer" a picture from my app to MS Word. I have a picture in the PictureBox, and I need to move it to a ByteArray.

How may I do that ?

Best Regards

Do you have any examples of retrieving a Word Document (Blob) stored in SQL Server into Microsoft Word using VB.NET?

You'll have to convert the BLOB back into a file, then open it with Word. Three distinct steps. There are many example of retrieving blobs all over the Web. Try this[^] for a start. The rest is easy, save it to a temporary file and the launch it using ShellExecute.

how Can I use events from base classes?

gaesquivel10-Dec-04 2:45

10-Dec-04 2:45

I try, but a message appears! "Can't use event from base classes (or similar)"

so I wrote a shadows Event in the inheritate class to replace the original Event, but no other object what subscribs to the shadows Event don't capture it!

What can I do?

Example

Class BaseCls

public Event OnMessage()

End Class

Class A
Inherits BaseCls

Public Shadows Event OnMessage()

......

Sub DoSomething
Raise Event OnMessage
End Sub

End Class

Class Other

private withEvents Obj1 as A

sub new
...
addhandler Obj1.OnMessage, AddressOf SubDel
end sub

.....

sub SubDel()
'this don't work???
'Event capture don't work
End Sub

....

End Class

Hi Gabriel,

Just implement a function or sub in your base class that actually contains the code to raise the event, then call that function or sub from your derived class.

You'll need to locate a 3rd party "viewer" control you can drop on your form an use. Or you can use the components that are installed with Office. There's a catch with that though, the controls are heavy and are a pain to use if all you want to do is view a document.

How to check " charector in VB

You have to use a regular expression :

<br />
Imports System.text.RegularExpressions<br />
<br />
Module RegExpTest<br />
<br />
    Sub Main()<br />
<br />
        Dim Str As String = "fazerty""uiopqsd"<br />
<br />
        Dim RegQuote As New Regex("""")<br />
<br />
       Console.WriteLine(RegQuote.Match(Str).Success)<br />
<br />
        Console.ReadLine()<br />
<br />
    End Sub<br />
<br />
End Module<br />

And, by the way, it's "character", not "charector" Wink | ;)

If you use the InStr func, it will look something like this:

Dim WhereIsTheQuote As Integer

WhereIsTheQuote = InStr( 1, original_line, Chr$(34), vbTextCompare)

As you might have guessed already, 34 is the ASCII Chr$acter code for the quotes. If there are any quotes, the place where they first appear on the string will be returned. If there are some more quotes, other than the first ones, they will not be reported by InStr(), keep that in mind.

Linking DLL's

How do I link my basic exe VB program to a dll in order to access the prototypes available in the dll?
I downloaded the DLL and now it's sitting around cos I don't know how to access it...

Re: Linking DLL's

Dave Kreskowiak10-Dec-04 3:24

If it's a plain library .DLL, you'll need the docs on it. Without them, you'll be groping around in the dark. You can get the function names using the Depends utility that came with Visual Studio 6, but you won't be able to get the parameters that each function takes. It's simply not available from the .DLL itself.

There are exceptions to this, of course. First if it's a COM registered .DLL, you set a reference to the .DLL instead of using Declare yada yada yada. All public functions will be available with their parameter lists. Or, if the .DLL comes with a .TLB file, you can import that as a reference instead.

prevent form from closing

Nadroj9-Dec-04 10:12

Nadroj

9-Dec-04 10:12

im wondering how you can setup a form so it cannot be closed?

i am trying to have a form so that the only way to get rid of it is to press a button on the form, which will only .hide() it. and another button on different form will .show() it, restoring all of it's window settings, etc. this is including when the user presses alt+f4 or hits the X (close) button, to hide rather than close the form.

...

i was just reading up on it, and it seems to work like this:

Private Sub BrowserForm_Closing(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles MyBase.Closing<br />
    e.Cancel() = True<br />
    Me.Hide()<br />
End Sub

this the proper way to do this?

thanks for any input.

If your application goes through a web service, it won't have any direct connection to the database. The web service should handle all interaction with the database.
