You need to use the Controls property, which all forms have, and it seems all controls have. So your panels can have a collection of controls. You can do this
dim lControl as Control
for each lControl in Me.Controls
...
Next
Me is a form or Panel or any control.
The typeof works the same.
Hope this helps.

may i know if there is any sample codes on how to link vb.net GUI with c++ DLL functions? thanks
|

That is hellishly difficult. C++ compilers mangle the names of classes and functions so that they can be uniquely identified. The names exposed by the DLL will be the mangled versions such as "@MyClass@#SomeFunction@$%$@%@@". The mangled format is different for most compilers, and sometimes different between different versions of the same compiler.

Like Colin said, LINKing is hellishly difficult. Or are you trying to CALL functions in a C++ .DLL. If so, you can start reading up on it here[^]. This is an article showing how to call DLL functions using P/Invoke in VB.NET. VB6 is very similar to this.

Hello All..
I guess you have see attachments embedded in Word Document like email having attachments.
I use MSWord automation with VB to get those attachments. I can only get the name of the attachments but can't find the way to save them.
If you have the word document which contains attachments like .jpg, .pdf, .xls, .ppt files, select one of the attachment files and either right click or go to Edit menu of Word application and you will see
File Object-> save as, open, print, convert.. etc.
I think there should be the function that allow me to save those attachments programmatically since you can save them mannually in MS Word.
I want to save as the attachment.. and cannot find the way to do it in Word reference.
does anybody know how??

This doesn't make any sense to me. Do you want to create a new font? Or do you want to use fonts that have the same character sets? Or are you talking about typing chracters in a text box in the local language?
In any case - I think what your getting at is "localization". For more information on localization and VB6, you might want to start here[^].

hi rage
thanx for your reply. yes i am "talking about typing chracters in a text box (or in any editable intrinsic control) in the local language?. is this possible ? can you show me a way out here please ?

OK. Now your definately talking about localization, not to mention depending on the keyboard the user is using. If your going to be accepting input in German or Arabic, it's best to use a German or Arabic keyboard. You can change the font to something that supports the language your using, but no font supports every character of every language your using.
You can change the input language and font using the "Regional and Language Options" control panel in Windows 2000/XP. But your app is also going to have to be designed to handle such a situation. How to do this is covered in the topic of "International Issues" in the VB6 documentation, here[^]. It also includes an example application that demonstrates how to resolve the issues of localization and accepting input in different languages.

Is there a way to get an up/down control to appear on a property grid such that I can use it to edit numeric values?
All the UITypeEditor stuff seems intent on popping up dialogs and showing dropdowns. I can't believe that the grid doesn't offer this as a default choice for numbers, it would be soooooo nice.
Perhaps there's a way using child controls, but then you have the nightmare of what to do when the property grid scrolls and aligning an up/down control with a row in the grid.
Any ideas would be appreciated.

Hi,
I'm working on a VB.NET project and my objects should be reachable using COM. My problem is that these objects have overloaded methods, properties, which seems problematic.
For example I have a collection class with two item properties:
Default Public ReadOnly Property Item(ByVal Key As String) As Object
and
Default Public ReadOnly Property Item(ByVal Index As Integer) As Object
When I try to use an object of this class in a COM only environment - like MS Word - there only one Item can be seen, and allways the first. So using the order above I can query collection items only by Key, when I change the order I can query only by Index.
This problem does not occour under .NET.
My question is: how to do VB.NET overriding, polymorphism to satisfy COM requirements?
(K)

|

COM can't expose overloaded methods through Automation - it's not part of the specification. The .NET Framework selects one of the method overloads to be exposed to COM.
I think you can select a different overload to be exposed by using the ComVisibleAttribute attribute to hide the ones you don't want COM/Automation clients to see.
The other alternative is to give each overload a unique name (removing the overloads).

Is there some way to cause a RaiseEvent in an ActiveX EXE to fire with out using the firing of some other event as the trigger ?
Every example of a RaiseEvent that I have been able to find uses a timer to fire it.
The books go on to warn that it is necessary to kill the timer when you're done with it and that there could be other programs that are using it and killing it can strand them.
The same problem applies if you use a form whether it contains a timer or whether you use a click event or something.
Of course it's possible to write code to check to see if any other programs are using it, but that of course is also not foolproof.
Also, is there any other way for an ActiveX EXE to initiate contact with a client (or multiple)? 
I posted this befor but somehow screwedup the subject so it made no sence .

Sure! All that's required is a RaiseEvent statement. It doesn't have to be inside an event handler for some control. You could put it in a loop, if you wanted, or any other construct. I've put them in puzzle solving code that uses RaiseEvent to notify of status changes. This was done inside of a LONG running solver loop running on a seperate thread (VB.NET.)
firefalls wrote:

Define "contact"? Is the client running some sort of server that our ActiveX must use? Your "clients" must be listening for something in order to respond to your ActiveX's request for a connection.

What ???????????????????????????????????????????????
Then how do I do that ?????????????? ...........
I asked the question, not just because I do not find any other examples in the books (or other guide sources)
but because I have tried to do this numerous times in the past few months,
my clients just do not respond to the RaiseEvent unless it IS part of an event handler which is executing
due to its event having been fired. (But even when it is part of an event handler, the client still ignores the RaiseEvent
if the event handler is executing due to having been called from somewhere else even if that is another event handler)
Also, I am using VB 6 rather than VB.net I have no idea whether that makes a difference are not I did not think it was supposed to but...
So, can you help me please thank you... John

It should work without any problems. Let me take a look at the code you've got. Send me what you've got and I'll see what I can find out.

Send you what I have............ OK..........
One: send it where? I clicked on the e-mail link at the bottom of your first response
and attempted to send something to you, but there was never any reply. I am assuming that for some reason it never got to you though I have no idea why.
Or should I just go ahead and posted below this? I am new to this site and don't really know how it all works.
Two: what I have is very little because most of what I had was on a second hard drive which fairly recently died (completely and without warning, all of a sudden its controller card would no longer recognize it)
thanks for your help so far.
