Try more on:Geocities[^], free vb code[^] and kidware software[^]. Kidware software contain a free trail documentation about beginning vb6, vb.net. If you want to try to can go to this website. I can start programming on vb6 since the last 5 years by the tutorial from this website too. Good luck.

Hi,
I want to detetmin parent class
For instance there is a Cars collection with Car item.
Cars collection has some property that I need to access from Car item.
CarsCollection
Property_01
Property_02
CarItem(s) (Type, Name, Year, ...)
I want to obtain the value of Property_02 from CarItem(5).
Every CarItem is already inside Cars collection and I am sure that there is way to obtain parent class.
How to do that?
Do not send answers like "You have to hold a reference to the CarsCollection in the CarItem"
I think that is something about iComponent, Reflections or something similar. .

Hi,
I am using collection to bind data to datagrid.
Dim oCars as CarCollections = New CarCollections
DataGrid1.DataSource = oCars
Everyithing work fine but there is a sorting problem.
If I do so, there is no sorting features in DataGrid. When I bind DataSet to Datagrid I can Sort data in DataGrid by clicking on columns header. DataGrid automaticly sort filled data according to clicked colum.
When I bind datagrid to Collection that features is missing.
What should i do, in Collection class - CarsCollection, to have sorting features back
Thanks in advance
P.S. Sorry for bad English

Hi everyone, I am totally fed up of this, see if anyone can help me out..
1. I have a datatable which is bound to a datagrid,
2. I have a datepicker placed on the 2nd column in the grid,
3. I am able to assign the datepicker values to the particular cell.
4. but, when the use clicks the clear buttton in the datepicker, I have to clear the cell(which already has some date in it)
I am unable to do it. I searched everywhere (msdn, codeproject articles..)
In one case they have mentioned that the empty() property will clear the values, But it does not work with the date field.
so, if anybody has the solution for this prob, help me out.

Thanks

Try SndPlaySound function:
Public Declare Function sndPlaySound Lib "winmm.dll" Alias "sndPlaySoundA" (ByVal lpszSoundName As String, ByVal uFlags As Long) As Long
Find more help on the MSDN.

This function only works with sound cards, not TAPI compliant modems...

You'll need to use TAPI 2.0 to get it to work. Search the User Samples at www.GotDotNet.com for the term "TAPI" to find a project that wraps the TAPI 2.0 API into a nice little .NET Framework class library.

No I don't. I've never used TAPI and, more than likely, never will.

Ok, this is simply amazing. I have been a user of VB for years and can not belive that MS took a step backwards.
It took me 30 minutes to figure out how to add a custom toolbox icon to my usercontrol and I cannot belive the hoops I had to jump through to do it.
I had to add an attribute to my usercontrol class to point to an embdeded resource in my project that was an ico file the same name as my usercontrol class.
Simply amazing.. where the heck is the 'Toolbox Bitmap' property of my darn usercontrol in the designer!?!
UGH!

Dunno what's possible in VB, but once you click the X, the form is destroyed. If you can catch the close event, you can set the form to be invisible. It will need to be modeless, otherwise it will maintain the focus and your main window will not be responsive.

The reason the child form is destroyed is becuase you loss all references to it.
if your working in vb.net you need to create a variable in a different class, holding a reference to your created form, or the reference can be 'Shared' (which i don't reccommend)
if you are working in vb6, you can try do the same as for the .net (but i'm not sure if it would work) or try to create the form in a different parent form.
you can also monitor the form's 'Closing' event(.net) or 'QueryUnload' event(vb6) and then you can cancel the termination of the form and just hide it. in both cases you need to set the 'Cancel' parameter to 'True'.

Inside of the form_close event (or form_closing in VB.NET), you can cancel the unload, and hide the form instead.
Just remember to actually unload the form somewhere else in your code, or you will be sitting with a hidden form in memory.

If the program is still running, then on the form you are on use a button or a file menue option or some kind of event and recal the form you would like to open up. Its just like calling a form for the first time.
if that doesnt make sence feel free to email me at iamydd@bellsouth.net

How do a messenger server/clients updates the online/offline stat. in real time?
If the server has a connection for all the clients, (and there is a lot, 33000+ clients), you would need two or more computers??? I’m I right????
No good.
Server pings all of the clients??? Takes a lot of bandwidth from the internet line, and takes a lot of time.
Also no good.
Any ideas?

I'd have thought that there is a central database, which there needs to be to store IP addresses from login to login, and that each client requests the info for the users they have in their contacts.

But what if the client's internet connection is lost?
The client is stille online via. the database.

Our internet connection at work drops out quite a bit, and I've noticed it takes messenger about a minute to work out that I am no longer online.
