I am looking for al line-control for VB. (maybe VB.NET - But I still haven't switched to)
Ideally it would work like the "connections" between shapes in Excel.
The line should present a connection between some self-made controls. The user should be able to edit the lines, so that he/she can make a little network (1 to 2 screens full).
Up to now I've done some experiments with the existing line:
Determing the distance between the click(x/y) and a line => self-made "click" event ...
Thanks in advance.

Hi Everybody,
I need your help regarding Subclassing in VB.NET. I am developing a project in which I am using Web Browser Control as Winodws Explorer. Means I am providing most of the functionalities of Windows Explorer in my Web Browser control through my application. 
I would like to SubClass the Web Browser Control and want to get the DELETE notification when user clicks on a button provided by interface. Or when user Right Click and chooses the "Delete" option from popup menu provided by Windows. Or, in Windows XP, user clicks the left panel entry "Delete this file" option.
I try to Subclass the Web Browser Control and try to get the DELETE notification. But application is not stable and also I am not able to trap the notification.  While debuging or EXE of the application crashes as soon as I try to enter the mouse in the Web Browser Control. 
Please, could you help me in this context?
I shall be very thankful to you for the same. Waiting for you early reply.
Best regards,
Vilas Shewale

Subclassing in VB Classic is notoriously unforgiving. One time I had a program with a subclass that brought down the whole computer whenever it was run. 
I've had a lot of experience with subclassing in both VB Classic and C# so I might be able to help you.
Could you post your code? I might be able to spot a bug in it for you.
By the way, subclassing is much more stable when using an already-compiled dll like the SubClassing and Timer Assistant available at vbAccelerator[^].

Strange - I sent an email to you both direct and through CP the same night you posted here first. CP had an error, but the direct email wasn't returned, so I thought I had gotten through. Anyway, here it is.

Your problem probably has to do with the fact that the listview control that shows the files/folders is the one getting the delete message rather than the WebBrowser window which is its parent.
Fix: Get the child window's handle and the enumerate the windows to find a window with the classname "SHELLDLL_DefView". If this window doesn't recieve the delete messages, enumerate its child windows to find a window with the classname "SysListView32" and subclass it. Hefty fix, huh?

Hi,
Thank you very much for your help. It's working properly. I subclass "SysListView32" object of Web Browser Control and getting the messages from it throught VB.NET's "System.Windows.Forms.NativeWindow".
Thank you very much for your help.

Hi,
I am facing the same problem again but in different way now. I subclass "SysListView32" object to get the messages. It's working for other messages like mouse move, mouse over, etc. But I am not able to trap DELETE notofication in the same object.
MSDN help says the WM_DELETEITEM message is sent to the owner of a list box or combo box when the list box or combo box is destroyed or when items are removed by the LB_DELETESTRING, LB_RESETCONTENT, CB_DELETESTRING, or CB_RESETCONTENT message. So I try to trap the same message in my code. I am not able to get the DELETE notification by "SysListView32" object.
Could you help me in the same context? I want a message which will trap the DELETE message as soon as user will click on "Right click\Delete" or "Delete this file" from the left panel of Web Browser control.
Thank you very much for your help. I look forward to hear from you very soon.
Best regards,
Vilas Shewale

A listbox and a listview are to different things. List view notifications start with LVN_ rather than LB_.
BTW, you might want to try using the folder view's object model to intercept delete messages rather than trying to subclass the control.

Soon I might be able to do this, but for now, look at the code in the file "folder.htt" in your Windows directory. This code deals with selecting, deleting, etc, of files/folders in the list view in explorer and the folder view.

Hi
What are the limitations of Visual Basic as compare to Microsoft Foundation Classes(MFC)?
e.g.
What we can't do in Visual Basic but it can be done using MFC.
Thanks

Just curious, but why aren't you asking this in the C++ Forum? Don't you think you'd get better answers there?

You're also not asking a question that has a direct answer. MFC is a bunch of classes/wrappers that make Win32 programming easier for C++. VB has access to about 90% of the Win32 API.
What are you thinking of doing?

Why only 90%? In my humble experience, there are no WIN32API calls that cannot be made throuhg VB - at the end of the day, the WIN32 API itself is just a collection of C dlls - admittedly, it is necessary to funk about with custom types etc from time to time, but there you go - if you use a screwdriver to hammer a nail, you expect it to be difficult!
Totally open to correction on this one BTW....

(VB.NET not included!) I was thinking more along the lines of mere mortal abilities. Multithreading, Shell Extensions, drivers, and such, are beyond the capabilities of VB6, or at least capable of being done by mere mortals!  . VB6 and below can only make ActiveX .DLL's. Not, IMHO, the more useful library .DLL's we all love to use.

Actually, Multithreading is possible in VB - have done it before - fairly straightforward in fact (and within the reach of a mere mortal (which is how I'd classify myself lol!) Ditto shell extensions. Drivers - yeah well, good point! Seem to remember that there is actually a way to do a straight .dll in VB, but may be wrong on that one!

Hi,
Is there a way to compile my VB6 project on a machine that does not contain the VB6 IDE? I've copied all of the files over and thus ported the VB6 environment, but I'm still having hang-ups. Has anyone crossed this bridge before?
Thanks!

It would be nothing like easy. You would have to have VB compiler and the linker console apps and would have to set all the compiler switches yourself.

You also have to port over the environment variables that get set, registry entries, path statement, any controls that your compiling with must be registered, ...
It's alot less time consuming to just install the thing...

If you have VB6 installed yourself anyway, wouldn't it be easier to just build it on your machine and use the resulting images - and in any case, simply copying files from one machine to another will NEVER work for anything more complicated than a standalone .exe - will need to register all sorts of components, ensure that the runtime files are present - big headache!

Hi folks,
I am kinda new to this .NET world. I am basically trying to inherit datagrid and create a class library with custom events and functions. Everything works fine expect when i make anychanges to the datagrid properties in design mode using the properties window. It comes up saying 'Object not set to an instance'. I am able to manipulate the code programatically, but not able to set any properties to my derived datagrid control in desing mode.
Did anybody had any similar experience??
