Hi! Guys,
I am learning VB.NET. I have an MDI Application, I have put toolbar and menubar on MDI Parent.
Now, whenever, user presses any of the button or clicks on any menu, I would like to catch that event in MDI child. Is it possible? I also would like to change states of buttons and menus as per the user selection.
Like, if user selects to add new record, do not allow user to navigate, print etc.
Which is the best way to work in this kind of situation? Some one told me to create individual menubars and toolbars on each MDI Child. Is that a good way?
I am really confused. Because, most of the applications are MDI, but I don't have any proper method to communicate between MDI parent and child.
Always, welcomes your comments and suggestions.
Ritesh.

I am getting info(Cal.SelectedDate) from form Calendar.aspx and sending it to TodayStudy.aspx to populate a datagrid. I am using a session called "GetPKIn". That part works fine, but when I go back to Calendar.aspx and change the info(Cal.SelectedDate) I'm sending to TodayStudy.aspx, the datagrid won't populate with the new info, it just keeps showing what it was populated with originally. The code is below. Thank you!

I have to write e programm similar to chess in VB.Net.Anybody can tell me where I find sourse for that or maybe help files and sites

Start by analysing the problem, then break it down into discrete areas. Then break it down some more...then some more....ad infinitum....
Problem with chess is that the logic on the opponent side (assuming it's a computer player) will be a BEAST.....probably some components / classes to help on t'internet though...

Do a google search on chess +"vb.net" - there are a few examples out there but you might have to convert from another language. I would do the search for you but my IE has been hijacked and I can't access most web pages anymore - I get taken to a Lycos search.

What are your goals? What features do you want?
I'd suggest you start by breaking your problem in to small manageable portions and then seeking help on any that still remain a problem.
First, write down a list of features that you want, if any are still vague then subdivide it again.
Second, prioritise the list - What is important to you? What is a must have? What is a nice to have?
Third, see if you've left anything out and add it in. Does it all glue together? How will it respond in the event of a system failing somewhere (for example, a network connection goes down)
Now, see if there are any area which you require further assistance on and you can post more specific problems, which more people will help with.

Does anyone know if you can control the harddrive directly. I want to beable to read or write to a specific sector to see what is contained in that sector. And can this be done with VB 6 or .NET or would you have to use a C type language. Thanks for any help

i thought with win 2000/xp/nt you couldnt control it directly because of the core design of the os [shell/kernel].
i know sum1 will help you about this, because i sure cant lol.
sum1 can reaffirm this or disprove it, as they will know more about it than me.

I know that you can not access the memory because of the protected mode that the OS operates at, but im not sure about the hard drive i think it is possible.

i thought it was all hardware, and in contrary i thought u could access the memory.
we'll have ta wait and c for a more knowledgeable response.

It's possible in VB6 and VB.NET, but not easily done. Since the hardware is abstracted from your app, there is no direct way of doing this. You have to go through the drivers sitting in the kernel to get the sectors for you. You'll be declaring a bunch of API calls and structures to get this to work.
C++ is a much better choice...

Hello,
I want to use a grid in VB6 that is capable of being bound to an ADO data source, and also is capable of hosting comboxes and other controls in the grid columns. Do the native Datagrid and Hierarchical FlexGrid in VB6 do this? As far as I can see, all the grids that come with VB are incapable of "hosting" other controls. Any comments or recommendations?
Thanks,

Looking to find how I can get a remoted object to contact client applications. I need to reference the application from the server process but there is no such thing as referencing an application. How can I get this done?
|
|

you need to have a bidirectional remoting channel.
I think the standard .net channel classes are only unidirectional. Search the web for "bidirectional remoting channel". I've seen such a tutorial but I can't remember where it was.

If I am not mistaken I just found a simple chat application. I believe it is raising an event on the objects that instantiate em. Is this the way to pull it off?
Thanks for your input Klaus.

It depends if the chat app is using remoting.
