hi
i'm trying to write a code for an application. this app will be installed on two or more computers and i want that the changes on the app on a computer will occur on other comp. at the same time. for example when a checkbox is checked on a comp., at the same time, the checkbox on other comp. will be checked.
i don't know can i explain the case but i need any help.
i think i must use sockets but how Smile | :)

thanx

It could be done using sockets or .NET Remoting. But, you have to implement some kind of command system in your app that can respond to these changes being made on the other instance. This is going to be a LARGE part of your project.

Why are you doing this? I can't see any possible reason that you would want to this...

First, thanks for the answer. It was just an example. Actually i want to develop an app that using a dataset. And this dataset will save entries that i entered with a form for entering data. This app will be installed on another comp and when we enter data, we would see the entries simultaneously.

I think this is a kind of an instant messagging.

Another idea is using xml web services. Is this suitable for the case? Or is the remoting the answer?

thanks again.

winform datagrid specific cell color

Remoting is probably going to be the best answer. Instant messaging is only a small part of the system you want to put together.

IM only sneds a message to another client. The client doesn't have to worry about which control to modify and how to modify it. THIS is the complexity you're adding, and you're adding a LOT of it. Your biggest problem is going to be concurrency. What if two people are entering something in the same field at the same time? Who wins and why? This is what you must deal with. Messaging is easy compared to this.

Creation of dynamic forms in visual basic 6.0

20-Dec-06 4:29

If it uses a HID-based driver, then yes, but how you do it depends on the driver and the functionality that it exposes.

You can find an example of doing something like this here[^]. There's also more resources on The HID Page[^].

What do you mean by "dynamic forms"? Creating new instances of a Form? Creating controls at runtime? What?

what actually my problem is i am working on microsoft project client project ( for project master planning). its like a tree structure.parent(Master plan) child(sub Masterplan, tasks) kind.here if one of the child get some update then every child and parent also required some changes.
ex: time period for one child is 2 days, but it took some around 5 days let us suppose. thin i need to modify the time period for every thing.
this is b'cas materplan have some limited time period

And what does this have to do with "dynamic forms"?

I don't do Office Interop stuff at all, so my help is going to be very limited.

I have no idea because the explanation you gave doesn't tell me anything about your application or how it's used or how your forms interact with the Project data or anything. It sounds like you have a serious data management problem that is at the root of your data model, but there's no way for me to tell you what that problem is.

Flatten the scrollbar??? That is somewhat ambiguous...do you mean flatten it's visual style or make it tak up less space?

I like to flatten the visual style of the scroll bar

Re: how to flatten scroll bar of a combo box in vb.net

I'm not sure that this is possible without creating a custom control (which i can't help with). Setting flat style to flat doesn't do it, so i don't think there would be another way.

Is there any code to create custom combo box with flat scroll bar?

The ANZAC19-Dec-06 21:08

Re: how to flatten scroll bar of a combo box in vb.net

19-Dec-06 21:08

That presents another issue, i don't believe that the scrollbar supports a flatstyle, this would probably mean the creation of a custom scrolbar to incorporate into your custom combobox.

If you don't mind me asking, what is this for? There may be alternatives. Does it need to be a combobox? and if so how many items does it need?

Actually i am developing an application in VB.net where each control in my forms are flat except Combo box. So i searched for flattening combo box where i could found only the text area and arrow button of a combo box are repainted in WndProc function of an inherited class of a combo box but not the scroll. So,Is there any solution for it?

Re: Maybe someone else can help you

As far as i know, scrollbars don't support flat look, that does not mean there is no solution, but i do not know of it. I've told you all i know.
