U should have knowledge of remoting. Once a class is running in the server . U can create a instance of that object in ur client throw remoting then use it how ever u want. Knowledge of reflection is added benefit.
Pls get an idea from this.

Hi,
If you are referring to Windows Forms, you have to create an object of the form before calling it.
Example: Create an object of Form1 in Form2 and call objForm1.Show();
But you will get a new instance of that form. If you want to go back and forth like in a web browser, you got to use usercontrols. Just use one form, and load the other forms inside this form. For this you need to have a master form and make usercontrols for other forms. There is a UserControl Class available in .NET controls, you can find it when you try to add a new component from with in a Project.

I want to trigger a behavior for which a third party component provides a keyboard shortcut. The user can trigger this behavior with CTRL+SHIFT+V, but I want to do it automatically in certain circumstances.
Any ideas?

I am not sure it is a great idea, but you can do keystrokes with the SendKeys. I think a better solution would be when you want to call the same method if you can see the event that is getting called I would try to call it. Or if there is a button that can be clicked you can always do button.PerformClick()
Hope that helps.

I’m working in a big MFC application. I now have Several Forms to add into this application. The original developer says there is no reason to stick with MFC. So I need to convert this MFC application. I’m looking for websites and/or books on converting. Both the old and new application will need to be written in C++.
Any advice would help.
Thanks

Hello
how can drag a row from a datagrid and drop it into a panel
plz help me
regards
etretyertyery

I've never had a need to write code like that but you can probably do it this way:
Set your panel's AllowDrop property to True
Trap the OnDrop event for the panel and inside the handler check the SelectedRows property of the datagrid.
You would then use that property to display the data any way you chose.
Again, I don't know if that example alone will do it bit it will be very close.
You might even do a google search on DragDrop operations.

You can add checkbox to a DataGrid.

I'm working on a game API which uses potentially transparent controls for basic layering effects (I don't want anything too fancy just yet). My first problem was enabling transparency, but that was easily solved using SetStyle(). Unfortunately, when I then tried placing a transparent layer over another layer, it shows the form's background color (here, black) through the transparency, instead of the layer beneath.
I was finally able to get the proper effect by making the top-layer control a child of the bottom-layer control, but doing it that way makes some other effects nigh impossible. Is there a way to get transparent controls to display the other controls beneath them? Any help is appreciated.

I would advise you to create you own class for layered effects. Its not as hard as it sounds! My method for creating your app would be to draw all my layers from my custom classes.

This is exactly what it's supposed to do. The color Transparent is anything but. Transparent tells the control's background properties to match those of the parent container. It does NOT make the control Transparent. As you've found out, control-over-control transparency doesn't work the way the term "Transparent" would lead you to believe.
The way around this is to not use controls to draw your graphics. Instead, you should be drawing your graphics to an off-screen buffer and "flip pages" between what's being drawn on and what the user sees, or use DirectX, where you'll have FAR more control over your graphics.

I was afraid of that. Actually, I'm using a custom OnPaint handler, so I guess FillRectangle() et al. is where that "feature" lies?
Thanks for your suggestions. I'd rather not get into DirectX just yet, but if that's what it takes....
P.S. Are there ANY functions (preferably GDI) that handle transparent and semi-transparent colors properly?

Since Windows Forms is based on GDI+, no, there isn't.
