The USB port doesn't work like a serial or parallel port. You have to write your code to communicate with a specific device attached to the bus. How you do that depends entirely on the device your trying to do something with.

Hello
I am using VS 2005 CR 10.
I am using typed datasets to populate a report.
From my database I have 1 field called incidentDate, this is a smallTimeDate datatype.
My reports always displayes the correct date, but is followed by the time which is always 12:00. For example 18/12/2006 12:00 AM.
I don't want to display this time. I have tried setting the DateWindowsDefaultType in the report properties for that field. But this did not work.
Does anyone have any other ideas,
Thanks very much,
Steve

Imports WMPLib<br />

i can create a play list, play selected media and all that but i can't get it to select a play list from file and play it . i looked briefly at the "currentplaylist" and other IWMPPlaylist but they only have functions that adds to a play list. i just want to simply select a play list from a storage area of choice.
any help would be appreciated. thanks in advanced.

Hello,
I am writing a problem that populates a combo box. When the user selects something from the combo box, they will press a tab key that will take them to the next control. However, i have tried using the keydown, keyup, and keypress. All these capture the other keys but not the tab key.
Sample of what I am trying to do.
Private Sub ComboCompany_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles ComboCompany.KeyDown<br />
If (e.KeyCode = Keys.Tab) Then<br />
MessageBox.Show(Keys.Tab)<br />
Else<br />
MessageBox.Show(e.KeyValue)<br />
End If<br />
End Sub<code><br />
<br />
many thanks for your help,<br />
<br />
Steve

What exactly are you trying to do?
You could use the leave event of the combobox to know when the focus moves from the combobox to any other control on the screen.

Yes the leave event would be a better option because a windows form intercepts the tab key. Leave event would be a hassle free workaround.

Hello All!
Seems pretty simple, but this is my first attempt at printing. There are alot of options when it comes to printing. All I need to do is click on a button, and have that event print a pre-selected text file. Just a file created in notepad, 4 lines of text. I don't need to preview it, and just use the default printer. I don't need the user to set up any settings, just hit the print button, and that text file will get printed. What is the easiest way to accomplish this?
I'm working in VS 2003, vb.net.
Thanks!

you can use 'print document' component from the toolbox and handle the printing event for that component. something like using grapics.drawstring function

I am working on a project that requires the ability to view a tiff file and be able to zoom in and out. Anyone know of a control that can do this in VB.Net 2005?
Thanks

If you want that kind of functionality written for you, then you'll either have to look for a 3rd party component to do it for you or write it yourself.
Either way, you'll need to either write or find a 3rd party component to support TIFF files anyway, because TIFF support in GDI+ is limited. There is no support for JPEG compressed TIFF files in GDI+, and hence, no control that depends on GDI+, like the PictureBox control, will work with them.

Hi,
does anyone know of some sort of freeware program that can analyse a .net component or application so see how its made up?
Im guessing some sort of reflection?
Regards

There is nothing that will "analyze" it for you. I have no idea what you mean by "see how it's made up". But, there is always the most indispensible tool on the planet Earth -> Lutz Roeder's .NET Reflector[^]

Why not write up your component with source code and publish an article here at code project. That is what the spirit of the site is all about sharing code. No one is interested in spam in the message boards, which is what your post is.
I'd love to help, but unfortunatley I have prior commitments monitoring the length of my grass. :Andrew Bleakley:

i am using dynachart activex on a form. when the chart is refreshed the whole form flicker.

Is DoubleBuffer active on the form. in .NET 1.1 you can use the SetStyle command. If you use .NET 2.0 you can use SetStyle and/or the DoubleBuffer property. Either of these two ideas might help with the form flickering.
Another possibility would be to see if the activeX has a refresh event and set a handler for the event that will also refresh the form before the flicker.

The Windows API call for LockWindowUpdate will control your form flickering when you do a lot of updates to controls.
In a code module, put this in your declaration section:
Declare Function LockWindowUpdate Lib "user32" _
(ByVal hWnd As Long) As Long
Then add this Sub to the same module.
Public Sub LockWindow(hWnd As Long, blnValue As Boolean)
If blnValue Then
LockWindowUpdate hWnd
Else
LockWindowUpdate 0
End If
End Sub
When you are about to update the chart, call LockWindowUpdate:
' Lock the form's window to prevent refresh
LockWindowUpdate Me.hWnd, True
' Do your thing with the chart...
' Unlock the window to show the updated form
LockWindowUpdate 0, False
I haven't tried this with chart controls, but it works OK with TreeViews and ListViews.

visual studio 2003
i wrote a custom container control for my project.
i compiled it to .dll, inserted it into 'windows forms' in toolbox, and then into my form.
now i moved the folder that is containing the original dll, thinking there will be no trouble, since my project folder also contains that dll.
didn't work, of course.
so how can i make sure, the programme always uses the dll that is included to my project folder, instead of using the original file in some folder that might not exist any more or at least not on the currently used computer? i have to develope my programme on different computers and everytime i copy the project to another computer, the source code doesn't work anymore, because the dlls are "missing" (i.e. the original dll's folder is on another computer).
what can i do?

Be sure the dll is in your project directory, delete the reference to the dll in your project, add the reference back to your project; but from the dll in your project directory, right click on the reference and select propertys set 'copy local' to false

Hi, I've been trying to add abutton to the outlook commandbar and have a problem with the following code
Dim commandBar As Office.CommandBar
Dim firstButton As Office.CommandBarButton
Dim secondButton As Office.CommandBarButton
Private Sub AddToolbar()
Try
commandBar = Globals.ThisAddIn.commandBar
Catch ex As ArgumentException
End Try
If commandBar Is Nothing Then
* commandBar = Globals.ThisAddIn.commandBar.Controls.Add_(Office.MsoControlType.msoControlButton, 1)
End If
It generates an error on the line with a * saying "Object reference not set to an instance of an object." Any ideas why?
