Hi all:
I need to get mouse position information which is easy enough to do with the form's mouseMove event. I've noticed, though when the mouse passes through a control, the flow of x,y coordinates stops.
How do I get a continous flow of information? I suppose I could add a mouseMove event to each control, but that seems like a kludgy way of doing things.
Thanks,
Norm

You could add a handler in your form for the controls when you add them. Something like this:
Public Sub AddControl(ByVal Control as UserControl)
AddHandler Control.MouseMove, AddressOf HandleMouseMove
Me.Controls.Add(Control)
End Sub
Private Sub HandleMouseMove(ByVal sender As Object, ByVal e As MouseEventArgs)
'handle your mouse move stuff
End Sub
Hope this helps. As well, don't forget that if you use AddHandler to add an event handler, always have a RemoveHandler when you close your form, otherwise your application will have a memory leak.
Public Sub RemoveAllControlHandlers()
For Each Control as Control In Me.Controls
RemoveHandler Control.MouseMove, AddresOf HandleMouseMove
Next
End Sub

Why not create a module that contains global variables? In form2, you can place the information into a global variable. Then, when you close the form and/or get back to form1, it will be there.

i suggest you start here[^] and follow through the different links, do a few exercises, etc. the basic concept is pretty easy
connection object > data adapter > dataset
if you know how to work with these data access is a breeze. there are other methods as well (of course) but get started with these and have fun

i create a Class that creates an excel file from a datatable. but the final sheet in the excel workbook looks awful!!? the columns of datatable are sorted alphabetically in the excel worksheet.here's my class source code:
Imports Microsoft.Office.Interop
Imports System.Globalization
Imports System.Threading
Public Class CreateXLS
Public Sub GenerateXLS(ByVal Table As DataTable, ByVal TargetXLSPath As String)
Table.WriteXml("C:\tmpxls.xml")
Dim oldCI As CultureInfo = Thread.CurrentThread.CurrentCulture
Try
'Start Excel and open the resulting file.
Dim oExcel As New Excel.Application
Thread.CurrentThread.CurrentCulture = New CultureInfo("en-US")
oExcel.Workbooks.Add()
oExcel.Workbooks.OpenXML("C:\tmpxls.xml")
oExcel.ActiveWorkbook.SaveAs(TargetXLSPath)
oExcel.Application.Quit()
Catch
Throw New ArgumentException("Error in File Saving")
Finally
My.Computer.FileSystem.DeleteFile("C:\tmpxls.xml")
Thread.CurrentThread.CurrentCulture = oldCI
End Try
End Sub
End Class
Can you help me to save target worksheet as it is on the source datatable?
thanks

You might want to just open the XML file in Excel yourself and see what it's doing. Since none of us here can see your XML file, it's about the only way you're going to see what you need to do to get in in the format you want.

Hello to all
I have a computer used as PDC and File-Server. SUSE Linux 9.3 is installed on it and the files are released for the net with Samba.
MS Visual Studio 2005 is locally installed on my notebook whereas I would like to save my projects on the file server.
Now, when I open a project I always the message that the location for the projects isn’t confidential/ protected enough and that when processing the application actions could occur which need “”full reliability”.
It’s possible to ignore this warning message and to continue but when testing the programm a new message appears: “Never enter personal information or passwords unless you can check the source and rely on it”.
I’m programming an application in Visual Basic which accesses the SAP System via RFC. When giving the command Create Object(”SAP Functions”) I get an error message “Security Exception wasn’t treated”.
When saving the project locally, everything works smoothly. Does anybody has any idea for solving the problem?
Thanks a lot in advance!

This is because of Code Access Security[^]. Code running from an untrusted network source runs in a restricted sandbox. This is why you're getting all these errors. Move the project to a local folder and you won't get any of these errors.

I have package my application and install to another machine, if the user just click Start --> Run and then type short word after that run my application automaticial. Example as notepad
Thanks
................

in your deployment you will need to install a shortcut to the app in the client machine's system folder. give the icon the short word you would like to use as its name, when users type this word into the Run dialog it will call the app to run.

|
|
Should i install short cut application system folder 32?
Thanks
................
|
|
|
|
|
yes.
you can install to this folder in your setup project by:
1. right-click on setup project. select "View > File System"
2. on the main menu bar click on "Action > Add Special Folder > System folder".
3. create a new shortcut to your primary output in the system folder you have created and name the shortcut the short word you wish to use.
4. build and test.
hope that helps.

Registry.CurrentUser.OpenSubKey(path,true)
Registry.LocalMachine.OpenSubKey(path,true)
both return nothing, i do not know the reason, pls what will i do for getting result
(i am trying to get the IE properties of Header and footer)
pls help me

|

is path correct?? same path cannot be run on both LocalMachine and CurrentUser, LocalMachine is used for HKEY_LOCAL_MACHINE and CurrentUser is used for HKEY_CURRENT_USER. path should be relative to them. when wrong path is provided, these functions return nothing.
