Re: .NET-BroadcastEventWindow PaleyX12-Jun-04 6:30 PaleyX 12-Jun-04 6:30  Just looked this up on Microsoft.com - they don't appear to have heard of it although they must have written it. There are quite a few posts about it if you do a google search, nobody knows what it is and nobody has a solution. Oh well, my users will just have to do without charting.

This includes just instantiating it and not disposing of it properly before your app shuts down. THis is why you can't find an answer on any sites. Depending on the chart control, the answer to how to dispose of it will be different. What is probably happening is the chart control you are using, a COM component do doubt, is firing off an event that you subscribed to, but since your app is already being GC'd, the call to your event code is going to where the event handler WAS in memory, which is no longer valid.

It's a shame because it looks a decent chart control (there's a lot of rubbish out there) How can I dispose of it properly? Rugby League: The Greatest Game Of All. Re: .NET-BroadcastEventWindow Dave Kreskowiak13-Jun-04 8:30 Dave Kreskowiak 13-Jun-04 8:30  You don't need to subscribe to an event. I just read up on the control's documentation. It's almost 100% C#. The remainder is UNMANAGED OpenGL code. You'll have to dispose of the component yourself. Something like this: ChartGridControl1.Dispose() ChartGridControl1 = Nothing If that doesn't work, consult with the Xceed and see if they have a fix for it.

I have sent off an email to Xceed, they are usually pretty good at answering queries. I wish these things didn't happen on a weekend. Rugby League: The Greatest Game Of All. Help: Unicode in VB aida12_9912-Jun-04 3:36 aida12_99 12-Jun-04 3:36  Hi, I am Using VB6. I have to display UTF-8 characters in my TextBoxes, but It seems that VB6 does not support UTF-8. How Can I change the 'Encoding' of the TextBoxes into UTF-8? Please, Help Me!! Thanks. Re: Help: Unicode in VB Dave Kreskowiak12-Jun-04 7:12 Dave Kreskowiak 12-Jun-04 7:12  The textboxes cannot be converted to UTF-8 because that refers to the encoding of the string, not the object. VB6 will only use ASCII and Unicode strings, specifically, it uses BSTR as its native format. What are you trying to accomplish?

Its Unitoolbox tool. If you need Unitoolbox, please contact me: hapelec2003@hn.vnn.vn Good luck tramdtt Re: Help: Unicode in VB Dave Kreskowiak14-Jun-04 0:18 Dave Kreskowiak 14-Jun-04 0:18  The UI controls don't support Unicode.

Re: bitwise rotation Dave Kreskowiak12-Jun-04 1:58 Dave Kreskowiak 12-Jun-04 1:58  To move the data X number of bits to the left, you would use: Result = Value * ( 2 ^ X ) To move the data X number of the to the right, you would use: Resutt = Value / ( 2 ^ X ) VB6 and VS.NET 2002 don't have native bit-shift operators.

Ex: value : 1110001111000111 rotate : 5 bits result : 0111100011111100 But anyway thanks again, u want reply my question.It means to me.. Re: bitwise rotation Dave Kreskowiak13-Jun-04 8:24 Dave Kreskowiak 13-Jun-04 8:24  After a little research and testing, there is also a problem I forgot about. In VB6, the shifting doesn't work in all cases because VB works only with signed numbers. If you use the techniques on &hFFFFFFFF (-1 decimal) and shfit the number ANY number of bits to the left, you'll get &hffffffff (-1 decimal). To get true bits shift support, you'll need a C++ .DLL to take care of the bit shifting for you. This is because C++ can work on the numbers as unsigned, doing the shifting correctly, then sending them back to VB6. Even then, you won't be able to do reliable calculations with those numbers because the sign bit will not be valid. You may think you have a positive value after a bit shift operation when you don't.

Rugby League: The Greatest Game Of All. Re: AddHandler / RemoveHandler Dave Kreskowiak12-Jun-04 1:56 Dave Kreskowiak 12-Jun-04 1:56  Sure. Just make sure your not removing the handlers while they are still being used and remember to remove the handlers you don't need anymore.
