For a window on the desktop it would be
window.Location=Control.MousePosition;
and for a moving Control held in some container Control it is
movingControl.Location=containingControl.PointToClient(Control.MousePosition);
as Control.PointToClient[^] translates screen coordinates to coordinates relative to the Control.
BTW: if you apply your (or my) logic to just one object, there is no way it could oscillate. And generally it is wise to test new techniques on one object only, until it works satisfactorily; this helps observation and understanding of what is going on.

Thank's that very informative.

really? all PointToClient does is subtract the screen location of the containing Control. I admit MSDN could have made that clearer (as usual), but if you think about it, it can't be doing anything else. So pick the right sucker before calling PointToClient.
Homework: how does a container figure out its screen location?

|
|
|
|
Yes, that is the method that does it if you feed it (0,0), but the question really is how does it do so? what is inside?

To expand slightly on what I said above (inserting some of the bits I glossed over with "yada yada":
bool catchme = false;
private void frmMain_MouseDown(object sender, MouseEventArgs e)
{
catchme = true;
}
private void frmMain_MouseUp(object sender, MouseEventArgs e)
{
catchme = false;
}
private void frmMain_MouseMove(object sender, MouseEventArgs e)
{
if (catchme)
{
Location = System.Windows.Forms.Control.MousePosition;
}
}
Top left corner of the form follows the mouse. If you want some other part to follow it, you need to offset the Location by the start co-ords of the mouse when first pressed down - not too difficult!
I really wouldn't use a timer for this, unless you want the form to move around on a pre-set (or random if you must) path.You should never use standby on an elephant. It always crashes when you lift the ears. - Mark Wallace
C/C++ (I dont see a huge difference between them, and the 'benefits' of C++ are questionable, who needs inheritance when you have copy and paste) - fat_boy

You would need to move the form relative to your cursor position.
Catch the mouse move event and then move the form relative to your co-ordinates.Me, I'm dishonest. And a dishonest man you can always trust to be dishonest.
Honestly. It's the honest ones you want to watch out for...

I've got a bit closer, I modified the code a little. Now I have a form that jumps when the cursor moves over it. I've now realized that the mouseover event may not work since I want the form to follow the cursor anywhere about the screen.
void Form1_MouseMove(object sender, MouseEventArgs e)
{
if (posx != e.X || posy != e.Y) {this.DesktopLocation = new Point(e.X - posx, e.Y - posy); }
posx = e.X;
posy = e.Y;
}

Hello guys,
I want to make a multi finance application and i need some example for my basic ground about multi finance. I had tried to search it on google but i didn't find it.
Maybe you guys know multi finance application whether it's a shareware or freeware?
Or maybe some good books for starting? the calculation related to multi finance etc?
Thank you guys for the attention.

Hi..,
Can anyone pls tell e how to convert the lat/long values to mils and also to georef?
|
|
|
|
|
|
Pls help me.. I am not able to find any apllication that converts lat/long to mils.. I am sure there is such example codes available
|
|
|
|
|
Look at the links in my reply. The last link is article on this site. Or are you looking APLICATION instead code?
|
|
|
|
|
Thank u but that just show the distance between two lat/long vlaues. I actually want the conversions. I'll go through it again and try to find if ther's any conversion used in it.
|

From what into what do you want to convert?
How to convert lat/long values to mils???
(From Title)
this kind of conversion is not possible. From lat/long you get only a fixed cordinates. while miles is a distance. They are not related. If you have 2 cordinates of lan/long, you can easly get distance and miles
|
|
|
|
|
I have no idea what you're talking about -- what's a mil?
|
|
|
|

A mil is 0.001 inch..45 ACP - because shooting twice is just silly

A degree of longitude (east/west) is a different size (in mils) depending on the associated latitude (north/south). Latitudes are about 111 kilometers apart, so converting kilometers to inches and multiplying by 1000 will give you the mils of latitude. The math is more intense for calculating the mils of longitude.
I think the best approach would be to determine how far a degree of longitude is from the next one at the equator, and then do some geometry based on the distance you are from the appropriate pole..45 ACP - because shooting twice is just silly

First, read this[^].
There are places on the Web to find the calculation of great circle distance, in kilometers, you can then convert.
On my last job I had to calculate the distance between two points, given latitude and longitude, but the points were generally within a hundred miles of each other (taxi trips within a metropolitan area). As such, we wanted the rectilinear distance, not the "great circle" distance, and we wanted it in miles. If that is of interest to you I could post it.

Am using MapwindowGIS with c#.net. How to connect legend and the map control?
|
|
|
|
|
in C dll:
void foo(unsigned short** buff)
{
*buff = &StaticArray[0];
}
in C# interop:
[dllimport : ...]
[May I know the method signature here ? ]
I want to make use of the memory allocated in unmanaged.
Thanks

I realy don't know, but acording to these articles:
Using Platform Invoke[^](In VB.NET with larger list)
Essential P/Invoke[^](In C# with short conversion list)
Acording to these, Int16 (UInt16 for unsigned) is used to marshal from c++ short. I do not know what these 2 characters '**' do, maybe you would need to use in, out or ref keyword
