Private Sub CheckBox1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged<br />
If Status.Text = "Not Connected" Then<br />
MsgBox("Interface is not pluged in", MsgBoxStyle.OkOnly + vbCritical, "Error")<br />
CheckBox1.Checked = False<br />
<br />
Else<br />
'The Code to Run My Program '<br />
End If<br />

Set a form level flag before you do the check bChecking to true, inside your event code return if the flag = true, this will short circuit the recursive loop. Then the last line (after setting the checkbox) set bChecking to false so it is ready for the next event. Something like the following
Private bool bChecking
Private Sub CheckBox1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged
if bCheckeing then return
bchecking = true
If Status.Text = "Not Connected" Then
MsgBox("Interface is not pluged in", MsgBoxStyle.OkOnly + vbCritical, "Error")
CheckBox1.Checked = False
bchecking = false
Else
'The Code to Run My Program '
End If
End Sub

Ok i tested it and that part you showd me works perfect now i have a other problem
When click the check box with the device not conectted i get the error msg box and the check do not stay thare that part works good
When click the check box with the device conectted it runs the code
If CheckBox1.Checked Then
NumericUpDown1.Value = CType(CTemp.Text, Integer) + 1
NumericUpDown2.Value = CType(CTemp.Text, Integer) - 1
and it works
But when you click to take the check out of the check box it will not run this code
Else
NumericUpDown1.Value = 0.0
NumericUpDown2.Value = 0.0
phidgetIFK.outputs(0) = False
phidgetIFK.outputs(1) = False
End If
witch it was working before i put the bChecking
Private Sub CheckBox1_CheckedChanged_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged
If bChecking Then Return
bChecking = True
If Status.Text = "Not Connected" Then
MsgBox("interface is not connected. Connect USB cable and try agine.", MsgBoxStyle.OkOnly + vbCritical, "Error")
CheckBox1.Checked = False
bChecking = False
Else
If CheckBox1.Checked Then
NumericUpDown1.Value = CType(CTemp.Text, Integer) + 1
NumericUpDown2.Value = CType(CTemp.Text, Integer) - 1
Else
NumericUpDown1.Value = 0.0
NumericUpDown2.Value = 0.0
phidgetIFK.outputs(0) = False
phidgetIFK.outputs(1) = False
End If
End If
End Sub
Thanks for every ones help

Look into Docking and Anchor properties of your controls.
There are some articles here on CP that may be useful, try searching.

for example on button click opendialogue file to select the document and parse it back to the textbox and then save it to the database..mind you it will be in byte..

I suggest you read the guidelines on how to ask a question - this request just irritates those who answer.

Why do you want to do this, you will lose any formatting in the word document. Then you intend to save it back to the database as a binary. Do a search on saving documents to SQL Server. I did this recently and found some excellent examples.

Using VB 2008 Express and MySQL 5.1.36 community server I created a database application whose idea is to keep some data about digital pictures (place taken, description, filepaths for the picture and so on). Works well to suite my needs. Through the app I can also create backupfiles using mysqldump. It is a standalone app. supposed to be used locally. MySQL uses MyIsam not InnoDb.
Via the mysql commandline it is possible to restore the database using the backupfile like this:
"mysql> source C:/dump.sql;" and that also works for a more complex path with more slashes in. It does not work with underscores in the path (or I did not bother to find a solution, I changed the actual paths instead to avoid that problem.)
Via the command line it also works like this:
"mysql> source C:\dump.sql;" however the beep sounds but the restoration takes place. So best use is the forward slashes /// in the first example to avoid the beeping.
The dump file is written to Create Database if not exists and the corresponding drop tables if exists is there. As I said, the dump file works to restore by the commandline.
Through VB then? Not a chance so far. I have read TFM but it doesn't have much to say. Google has been used but without success so far.
Friend Sub RestoreIt()<br />
Dim ArgumentString As String, UserString As String, PasswordString As String <br />
Dim str4Q As String = """"<br />
Dim p1 As New ProcessStartInfo, FilePath As String = App_Path()<br />
FilePath = Replace(FilePath, "\", "/")<br />
Dim DumpFile As String = FilePath & "dump.sql"<br />
UserString = "root"<br />
PasswordString = "blabla"<br />
ArgumentString = " --user=" & UserString & " --password=" & PasswordString & " source " & DumpFile<br />
<br />
Try<br />
With p1<br />
.UseShellExecute = False<br />
.FileName = "C:\Program\MySQL\MySQL Server 5.1\bin\mysql.exe"<br />
.Arguments = ArgumentString<br />
End With<br />
Process.Start(p1)<br />
<br />
Catch ex As Exception<br />
MessageBox.Show(ex.Message, _<br />
Me.Text, _<br />
MessageBoxButtons.OK, _<br />
MessageBoxIcon.Error)<br />
End Try<br />
<br />
End Sub<br />
Public Function App_Path() As String<br />
Return System.AppDomain.CurrentDomain.BaseDirectory()<br />
End Function<br />
The process starts but nothing happens. I dont know how to go on. Is it possible to read the process line by line and see where the errors occcurs? It rolls on like an thunderstorm with some lines. Or does someone have an direct answer to solve my problem? Where the dumpfile is located could not be the problem cause it works from the commandline from different locations such as C:/dump and C:/Whatever/Dump/Anotherdump/dump.sql
I tried with and without the """" (as in str4Q) before and after the filevariable but nothing works. Those four quotes is necessary when creating the dumpfile via mysqldump. I have also tried to write a batch file to run instead of the System.Process but no result.
As could be seen in the code I have replaced the back slashes with forward slashes. Tried the opposite and also with double slashes but no result.
Any hints are more than welcome,
leif, sweden

Finally, a nightly session with Google did it.
Thanks to the signatur "Guid" in the posted link here and his C# solution which was easy adaptable to VB.

In the above linked forum it also suggests to use a stored procedure within MySQL. Has to be tested...
But this code did it. Two namespaces had to be imported as well as a DLL import of "kernel32.dll".
Directory for batfile must exist. No error handling yet.
Imports System.Runtime.InteropServices<br />
Imports System.Text<br />
Public Class Admin<br />
<br />
<DllImport("kernel32.dll", CharSet:=CharSet.Auto)> Public Shared Function GetShortPathName(ByVal lpszLongPath As String, ByVal lpszShortPath As StringBuilder, ByVal cchBuffer As UInt32) As UInt32<br />
End Function<br />
<br />
Friend Sub DeKomp()<br />
Dim buffer As New StringBuilder(256)<br />
GetShortPathName(Path.GetDirectoryName("C:\Program\MySQL\MySQL Server 5.1\bin\mysql.exe"), buffer, buffer.Capacity)<br />
Dim shortfilename As String = buffer.ToString<br />
Dim batchfile As String = "c:\XBatch.bat"<br />
Dim sw As New StreamWriter("c:\XBatch.bat")<br />
sw.WriteLine("cd " + shortfilename)<br />
sw.WriteLine("mysql -uroot -pXXXX testbDB< C:/VB9/MyBkUps/Data/dump.sql")<br />
sw.Flush()<br />
sw.Close()<br />
Environment.CurrentDirectory = "c:\windows\"<br />
Process.Start(batchfile)<br />
End Sub<br />
End Class

0) What have you tried? (we don't just give you the entire program you know)
1) Please explain a little bit better.
1.1) is there a user interface (I'm guessing yes)?
1.2) are you using a openfiledialog to determine your original file or not?
1.3) are you using a savefiledailog to determine the destination or not?
2) look at the following namespaces:
2.1) system.io.file
2.2) system.io.path
2.3) system.io.directory
3) Your really going to have to explain your question better and post what you have try'd so far.

I have a USB drive which i want to monitor.At this time when i am copy the data and Paste in USB Drive i want to know the main source of coping data.
I want to know the main source of data where from it copied.
if u have any solution or idea please help.
Thanks
If you can think then I Can.

Unless your program is doing the copying I don't think you can find the original path of the data.
|
|
|
|
|
Since the copy originator can be anything, there's no way to find out who's copying what files from where.

For GMail, you can make use of Google Contact API[^].
For rest, I guess there should be something similar. You can also check out this[^] link.

Hi All,
I am tring to create a small application Screen Recorder in video format. Please give me the idea for doing this.
I try it by using Windows Encoder and DirectX.But i do not want to use any others Software Component.
Is this possible create video from Images.
Please suggest me.
Thanks
If you can think then I Can.

The most universal way to capture the screen and next write the result into file is using DirectX.You have to use Microsoft Screen Capture filter as source filter.Next just add renderers and grabbers to your graph as needed.You could use DirectShowLib to access DirectX from VB.NET of C#.Test the graph configuration with GraphEdit.
