Apparently I don't understand what PointToScreen() is actually returning. I'm thinking it should be absolute screen co-ordinates. In a form, I have some labels in a panel, which itself is in a panel and am trying to derive the screen co-ordinates for the labels in one statement without adding the X and Y co-ordinates of the panels. Why does PointToScreen(Label.Location) return the same value as PointToClient(Label.Location) and the same as Label.Location? Shouldn't PointToScreen() return absolute SCREEN co-odinates?

When two computers are connected through TCP, and one of them closes and breaks the connection, it throws error 10054 "Remote host forcibly closed the connection".I want to handle this error because I know it will happen more often than not with the application I'm building. In System.Net.Sockets.SocketException, there is an on the error code. But when I run the program, the exception that is being thrown is System.IO.IOException, and the GetType for IOException is the socket exception. I don't know how to handle the socket exception if it's not the root cause of the exception.

What I need is a code that can read from database (*.accdb). Form example if I select LG from Form4, it should read from a table from the database the price of
the LG, then we press "save", then should return to the Main Menu, then we select, for example, Scanners from the Main Menu that will take us to Form5. There we select, for example 24", that should take the price again from the data base and
add it, after save, to our first LG price, and return back to the Main Menu, and so on. The total price should appear in a new form, form7, after clicking (Total Price).

View 1 RepliesI have been developing my application for a while and need some advice on the closing. I want a code to be run when the close button is clicked but ONLY when it is clicked.
I have dried the form.disposed but that fires whenever the form is closed from the code. I just want it to do it when the close button is clicked.If you don't understand it I will give an example. I have a registation form that is the first thing a user who has not used the app before can see. When they click the close button I want the application to exit through Application.Exit(), however when they have registered the form is closed from the code through
formlogin.show()Me.close()However the Me.closE() triggers the form.disposed event and thus the application exits completely which I don't want. I know I can use the form.hide() but that keeps it running which makes the app more resource intensive.
What is the code for Hiding a mouse and make it go back when going to
Desktop1.vb
Cursor.Hide()
works
Cursor.Show()
is not working when going to Desktop1.vb .vb its still hiding what am i doing wrong here is my code.

My Front end is VB.net 2008.I have a form. In this form, I have a menu control, this menu control has four buttons.On clicking the first three buttons, open the window with Show() event. and the fourth button open the screen with ShowDialog().Now, One by one I am clicking the button , so finally i have now four windows of this application.(Three with Show() and one with ShowDialog())Right?
Now I am minimizing all the windows with the help of Window + D Button.After this, If I use the keyboard(Alt+ Tab) keys. This is opening the showDialog window on top because , Show dialog's TopMost = True.Now I come back to my problem. That's why I cannot use the show/Showdialog overloaded menthod to pass the Me/form-id .Again, I use the keyboard(Alt+ Tab) keys, to minimized all windows. In the taskbar and Startmenu properties ,I have selected the Group Similar Taskbar buttons.This resulted in the heap of my application windows, one on the other.Now i click on one of my application window , and If I click the window other then the Show Dialog opened Window, this is not bringing the show dialog window to topMost.
Note:- There is no parent child window requirement. That's why I can't use the Show/Show Dialog overloaded method to pass the Me/Form-id

if its possible to have mouse events like mouse movements, mouse clicks and so on in a specific window only. I'm not sure if you understand this so ill give you an example.
Okay lets say i want this program to only click within a window like Firefox or windows media player only. So that means if i minimize the window it will still click inside that window while its minimized, and i could continue doing other things while its clicking inside that window.
how do i check if a mouse was clicked in a specific coordinate plane on the form"?

When I deployed my project on a server, in certain circumstances, I get an error page that indicates I should create a custom error page. I was wondering how exactly I would implement this custom error page the server asks for to give me a precise and helpful message or preferably, how I would get the error to just display on the main page?This is the error message I got below
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
<!-- Web.Config Configuration File -->
<configuration>
<system.web>

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

I want to convert British OSGB 36 co-ordinates to WGS 84 (i.e. "standard" latitude and longitude), in order to plot them into a KML file for Google Earth.I should probably add that my question is not "How do I write a KML file?". My question is "How do I convert between these 2 co-ordinate systems?"!!I was hoping there would be a library that I could use, rather than rolling my own function - it seems like the sort of thing some-one else would have implemented.
