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 that is what i want
When click the check box with the device conectted it runs the code
and most of the time it only runs the code once i have to stop and start my program to get it working agine
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
This is my code for the check box
<br />
Private Sub CheckBox1_CheckedChanged_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged <br />
If bChecking Then Return <br />
bChecking = True <br />
If Status.Text = "Not Connected" Then <br />
MsgBox("interface is not connected. Connect USB cable and try agine.", MsgBoxStyle.OkOnly + vbCritical, "Error") <br />
CheckBox1.Checked = False <br />
bChecking = False<br />
If CheckBox1.Checked Then <br />
NumericUpDown1.Value = CType(CTemp.Text, Integer) + 1 NumericUpDown2.Value = CType(CTemp.Text, Integer) - 1<br />
Else <br />
NumericUpDown1.Value = 0.0 <br />
NumericUpDown2.Value = 0.0 <br />
phidgetIFK.outputs(0) = False <br />
phidgetIFK.outputs(1) = False <br />
End If<br />
End If<br />
End Sub<br />
I want to thanks everone for your help

I'm not entirely sure what you are trying to achieve but I think I see a problem with your code anyway.
* You first check bChecking, if it is not 'True', then you run the rest of the code
* Then, later on in the sub, you set CheckBox1 to checked, which I believe will then run this event again because after all, this sub runs when CheckBox1's check state changes!
* You now check bChecking again, but it is now 'True' therefore the event will exit (I think)
Maybe a better event handler would be CheckBox1.Click

How about simplifying things by scraping this and enabling/disabling the controls depending on if the device is connected/disconnected or not? That way, you're not trying to change the value of a checkbox inside the checkbox's own changed event.

you got me thare i thot i was on the right track here
do you have some information i can look at for the idea you have ??

I would probably be looking for a Connected and/or Disconnected event in the phidgets library. Something that tell's you a new device has shown up or been removed.

is it possible to show a pps or ppsx file in my form? I don't want to run it outside my application. I want to set the size of the show as my form size.

There's no way to do this if powerpoint is not installed. It *may* be possible to embed powerpoint as a control, but I have never heard of it being done. You'd have to read the microsoft tools for office docs to see if they support that.

Hi all,
I am newbie in outlook programming using vb.net.
i m facing write event problem of outlook.
The code is below. What i am doing in this code. i m getting all contacts form outlook and create write events for all contact. When i m trying to edit any contact from outlook 2007 and save that contact, then it is showing last contact name and body of contact which is last write by for loop given below. But i want to show those contact full name and body info which i edit.</b> I am using vb.net2005.
For i1 As Integer = 1 To contactFolder.Items.Count
contact = DirectCast(contactFolder.Items(i1),Microsoft.Office.Interop.Outlook.ContactItem)
AddHandler contact.Write, AddressOf Contact_write_Event_
Next
Public Sub Contact_write_Event_(ByRef cancel As Boolean)
MsgBox(contact.FullName & "-----> " & contact.Body)
End Sub
Where i m wrong please guide me.
Thanks a lot

Your post is hardly readable.
1 - Please don't use unnecessary bold letters.
2 - Wrap your code inside <pre lang=vbnet> </pre>.
3 - Indent your code properly.

First of all sorry for that
I think expert programmer don't see this type of thing like bold and alignment. They just concentrate on problem and write desired solution.
So please if you have a solution than reply otherwise no.
Again sorry for that Navaneeth

Errm, No we're human too, and in fact expert programmers will expect well written code and within set convensions.

With this sort of attitude, I will be suprised if anyone will help you now.

Hello Steve Jowett
you are right,
Actually i have posted near about 5 types of outlook problem in codeproject.com.
No one give desired solution of my problem except bold and italic and alignment issue..

I've got a VB.Net windows program that monitors a database
This progam sits in a repetitive loop. I would like to be able to output some data about what the program, had been doing in each loop.
The problem is that the listbox on the user interface does not display anything until the process has eneded.
Does any onw know how I do this?

Looks like you have only a single thread. Try to run the operation on a different thread. If you are adding items continuosly in a tight loop, use ListBox.BeginUpdate()[^] and once finished call ListBox.EndUpdate()[^]. This will prevent unnecessary drawing the listbox.

Thanks Navaneeth
I've tried using the update. It doesn't seem to do what I'm trying to achieve.
What I need is to be able to update the listbox realtime eg to show data flowing through (mid loop) rather then render the control with all data when the sub completed execution.
I want to build a data flow monitoring tool that sites on a desktop.
For the below code I'm aiming forthe application to pump a new item into the listbox visually in every iteration of the loop. I've added the thread sleep to slow it down and spread the timestamp apart.
Dim counter As Integer = Nothing
Do While counter < 100
counter += 1
ListBox1.Items.Add(" timestamp output " & Now)
Threading.Thread.Sleep(200)
Loop
Does anyone have any ideas?

Again, you have to move the code that is generating the data to a new thread, then Invoke a method on the form to update the ListBox on the UI thread. Don't worry about the BeginUpdate and Endupdate methods just yet. Worry about getting the data to the control from a background thread first.
You may want to look into the BackgroundWorker component if doing your own threading is a bit intimidating.

Hi,
as others have said, you need a separate thread to keep things running AND your GUI alive.
Choose one of Thread, ThreadPool, or BackgroundWorker.
The former is the most flexible, the latter often is the most comfortable. You could implement a loop in its DoWork handler, include a Thread.Sleep if you want to, and call ReportProgress() to report progress on the GUI; i.e. your Progress handler could add data to the ListBox. That would seem the easiest way to avoid cross-thread problems. And you might want to read this little article[^] if you would consider another way (Thread, ThreadPool; or even BackgroundWorker without ReportProgress).

I need to decorate my VB 2008 db app with icons for command buttons, data grid views etc. But I don't know where to go for a library of Icons to suit most situations. Can I have a top 10 with best value as a factor?
Thanks

There are free icons available on the Internet. You can get those if you search.

I recommend you use the fugee icon set. It's free and has a lot of icons.
http://www.pinvoke.com/[^]
Have you tried the Krypton Toolkit? http://www.componentfactory.com/free-windows-forms-controls.php

The Icon Factory do some excellent icon sets:
http://iconfactory.com/stockicons[^]
Not free, but not hugely expensive for what you get. Some very nice designs, too.
The fugue and diagona icons are nice (I have used them myself in the past) but if you use the free version you must include an acknowledgement in your application (that's what the $50 licence is all about, if you don't want to do that).
The crystal icon project is also very nice, but more Apple-oriented. They are covered by the LGPL licence. I've used these as well in the past, with good results.

Thanks for these suggestions. I'll be loking into the packages as these will give me choice and consistency. I appreciate there are lots of free sites where you can search for Icons.
My preference is to pay for a package that has a good library of styles and themes.
Any more suggestions for "Pay for Packages" with good choice would be useful.

My VB code has been successfully reading and writing to MS Access for a long time on 32-bit machines. In the code, the instructions for the connection string include
"Provider=Microsoft.Jet.OLEDB.4.0".
When I try the same code on 64-bit machines (Vista - Service Pack 2), it does not work and my error message says that Microsoft.Jet.OLEDB.4.0 is not registered on the machine. However, MS Access 2007 does work by itself. Any suggestions?
