Hi Colin,
yeah you're right
i know GIS would be the most logical solution but i think the people that have to manange those stations have no gis,
i guess the solution should be an application that perform only that specific "GIS like" analysis.
so my question was about the calculation and data structure to do it
thanks!

It is not a trivial solution. I spent 5 years writing GIS software (the core of a GIS system) and a further 2 on the business application end.
You could go for a simple as-the-crow-flies measurements, but that won't take into account things like the road network and so on.
If you can, I'd get a plug in component for your application and put all the data in that and get it to do the hard work.

you are very kind,
but the app i need is just a favour to a friend of mine, i guess you are thinking of serious "pro" application.
it has got to be as much easier as possible so the as-the-crow-flies measurements might be ok but i need to figure out how to take into account the portion of county covered by each station, to decide wich station belongs to a group instead of another or even if i can or not build up such groups.
i know, it'not trivial at all.
you seem to be quite skilled in geographical information systems, do you think that an "easy way exists" or not?
thank you, cheers!

Hi I am converting a C# code of the Office 2003 Menu by Mohammed Halabi to vb.net. But i am not been able to convrt some of the code. zhere is the code that i am not been able to convert
foreach ( MenuItem mi in menu.MenuItems )
{
// Add MesaureItem event handler
mi.MeasureItem += new System.Windows.Forms.MeasureItemEventHandler(mainMenuItem_MeasureItem);
// Add DrawItem event handler
mi.DrawItem += new System.Windows.Forms.DrawItemEventHandler(mainMenuItem_DrawItem);
// Set the OwnerDraw property to true
mi.OwnerDraw = true;
// call InitMenuItem Method to apply changes to child menus
InitMenuItem(mi);
}
The MeasureItem and DrawItem are events and they are not comming in vb.net how can i show events in the intellisense. This is a problem in vb.net. Events are not shown in vb.net.

In the Form's Load event handler, use AddHandler to set event handlers for each of the context menu's items' Click events.
' Use one event handler to select all line widths.
AddHandler mnuLineWidth1.Click, AddressOf _
LineWidthMenu_Click
AddHandler mnuLineWidth2.Click, AddressOf _
LineWidthMenu_Click
AddHandler mnuLineWidth3.Click, AddressOf _
LineWidthMenu_Click
AddHandler mnuLineWidth4.Click, AddressOf _
LineWidthMenu_Click
AddHandler mnuLineWidth5.Click, AddressOf _
LineWidthMenu_Click
|

|
|
|
sorry
AddHandler mnuBlack.MeasureItem, AddressOf _
ColorMenu_MeasureItem

I am trying to simulate a tool tip just like the one on windows explorer.
System.Windows.Forms.ToolTip shows the tool tip based on where the cursor is. I want the tool tip over the label regardless of the position of the cursor.
Thanks for you help.

how can i paste an item from a listbox to a textbox in the same form with a click of a button?
|
|
|
|

Without further detail, it's impossible to know exactly what you want. But, in the Click event of the button:
TextBox1.Text = ListBox1.SelectedItem.ToString()

I have installed Active Reports, now how do i get them to work with vb.net
Active Reports help file only tells you how to add it in VB6. I cant figure it out.
|
|
|
|
|
A better bet would be to ask Data Dynamics support to see what you have to do. As I understand it, it may not be supported under .NET, though, they do have a version specifically for .NET.
