Hi
Questions regarding ListView in VB6:
a) How can I display more than 1 icon in row?
b) how can I display an icon in a specific column? Using the SmallIcon propery always displays the list on the left. I want the icon to be displayed in the 5th column for example.
thank you.

I wonder if anyone can give me advice on the following?
On my PC I have visual studio 2003 and 2005. They work with no problems i.e. I have systems written in 2003 and systems written in 2005. I am now going to start a new project and this will be written in 2008.
1. Can you see any problems installing Visual Studio 2008 onto my PC i.e. will it clash with 2003 and 2005.
2. Will my previous systems in 2003 and 2005 still work?
3. Do you recommend this should not be done.
Any feedback would be most welcome.

I had all 3 installed on my system at one time and did not face any problems.
BTW - this question would have been answered better if you had asked it in Visual Studio[^] forum.

All three versions will coexist very happily on the same machine. Just be careful opening projects and don't convert projects you want to keep in the older versions of VS.

Visual Studio versions can coexist quite happily, however the last one installed will "steal" the relevant file extensions, e.g. when you double-click a .cs file in Windows Explorer, it will open in the VS version you last installed.

Once can right click and choose "Visual studio version selector". That picks up the right version (most times).

Hi all,
I have the below code I’m using [in VB.NET 2005] to populate three DataGridView’s I
have on my form without much success at the moment as the DataGridView
only displays one column of data once it has run :/
In the example I am just trying to get it working for one DataGridView
with the intention of passing in SQL to define the DataSet’s once its
working.
I am unsure weather I have missed something because I can view all the
data in the visualiser but it only seems to populate the one column in
the DataGridView.
Please help.
Scott.
Private Sub cboUserName_SelectedIndexChanged(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles cboUserName.SelectedIndexChanged
Dim lngUserID As Long
For i As Integer = 0 To ALWDBDataSet.Tables("tblUser").Rows.Count - 1
If ALWDBDataSet.Tables("tblUser").Rows(i).Item("UserName") = cboUserName.Text.ToUpper Then
lngUserID = ALWDBDataSet.Tables("tblUser").Rows(i).Item("UserID")
Exit For
End If
Next
'// Initialize a new instance of the OleDbConnection Class

Soooo where are you binding the new dataset to the DataGridView?? I don't see it anywhere.
|
|
|
|
|
On line 17 of the PopulateGrid sub
'// Bind the DataSet to the DataGrid
grd.DataSource = objDataSet
grd being the DataGridView that is passed into the sub "Call PopulateGrid(dgvLogInfo, "tblUserLogs")"

Have you defined your own columns in the DGV or are you using the automatically generated columns?
|
|
|
|
|
Ah, well this is where I might be going a bit wrong then – please forgive my ignorance but I thought [as I could see all the data in the visualiser maybe] that the columns would not need to be defined explicitly, when I look at the data in the DataGridView after the procedure has run the column headings of the table are in there, but as I stated in the original post only one column has data in it 
Tanks for the quick response.
EDIT: I used these two methods
grd.Columns.Clear()
grd.AutoGenerateColumns = True
And it seems to be working ok now.
Thanks for your help.

I have a Windows Form which uses a Timer to automatically close itself if no user interaction occurs within a given time.
The form contains a Label, a Button and a ListView control.
I basically want to run my UserHasClickedForm() sub if the user clicks anywhere in the form before the Timer ticks.
I've used the Click event of each of the controls as shown below.
The code works for each control except the ListView. If I click on the ListView control at run time, the click event does not get raised.
Anyone know why this is, and what I could do to fix the problem?
Private Sub MyPopupDialog_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Click
UserHasClickedForm()
End Sub
Private Sub MyButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyButton.Click
UserHasClickedForm()
End Sub
Private Sub MyLabel_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyLabel.Click
UserHasClickedForm()
End Sub
Private Sub MyListView_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyListView.Click
UserHasClickedForm()
End Sub

Did you click on an item in the ListView or a blank area??
Try wiring up the ItemSelectionChanged event as well as the Click event.

Thanks for the response Dave,
Using my code I've tried clicking on items in the ListView, blank area in the ListView control, Column Headers... Nothing seems to trigger a ListView_Click.
Ultimately I want to flag that the user has clicked somewhere on the form regardless of whether it's on a blank part of the form, a control on the form like a Button or a ListView Item, a blank part of the ListView control or a Header in the ListView control.
It seems to work as I would expect for all elements of the form except the ListView control, which has me stumped.
Then again perhaps there's an easier way than coding the click event of each individual element of the form?
Cheers
Paul

There is no easier way to do this. If you click on a control, you're no longer clicking in the form.
Like I said, wire up a different event for ListView.

|

you might try some other ListView event, such as MouseClick or MouseDown.
|
|
|
|
|
Damn! Forgot about those... 
|
|

|

You can also simplify your code by rolling up all the handlers onto 1 sub
e.g.
Private Sub ControlsClicked() handles control1.click, control2.click, control3.click
UserHasClickedForm()
End Sub
Even if your controls do something in their own click events, both will fire.
You could even remove the additional sub and attach the handlers directly onto UserHasClickedForm()

Thanks everyone for your help.
Using Dave Kreskowiak's and Luc Pattyn's suggestions for looking at other ListView events, with daveauld's suggestion for simplifying the code, I've gone from my bloat-code which didn't work, to the following elegant-code which does.
Public Class MyForm
Private Sub UserHasClickedForm() Handles Me.Click, MyLabel.Click, MyListView.MouseDown, MyListView.ColumnClick, MyButton.Click
MyLabel.Text="Clicked"
End Sub
End Class
- The MouseDown event is raised if you click in a blank area or Item of the ListView control, but not if you click on a column header if the View property of the ListView is set to Details.
- The ColumnClick event is required to handle clicks on the column headers.
Thanks again.
Paul

Sub SaveAsPDF_demo()
Dim oSM, oDesk, oDoc As Object 'OOo objects
Dim OpenParam(1) As Object 'Parameters to open the doc
Dim SaveParam(1) As Object 'Parameters to save the doc

Set oDesk = oSM.createInstance("com.sun.star.frame.Desktop")
Set OpenParam(0) = MakePropertyValue("Hidden", True) ' Open the file hidden
Set oDoc = oDesk.loadComponentFromURL("file:///C:/tmp/testdoc.odt", "_blank", 0, OpenParam())
Set SaveParam(0) = MakePropertyValue("FilterName", "writer_pdf_Export")
Call oDoc.storeToURL("file:///C:/tmp/testdoc.pdf", SaveParam())
Set oDesk = Nothing
Set oSM = Nothing
End Sub
Public Function MakePropertyValue(cName, uValue) As Object
Dim oStruct, oServiceManager as Object
Set oServiceManager = CreateObject("com.sun.star.ServiceManager")
Set oStruct = oServiceManager.Bridge_GetStruct("com.sun.star.beans.PropertyValue")
oStruct.Name = cName
oStruct.Value = uValue
Set MakePropertyValue = oStruct
End Function

In web forms - Is it possible to hide (visible=false) a complete row of controls with 1 command? And can this be controlled from code-behind? If so, pleasee show example...
Thanks in advance...

I'm looking for a way to monitor drive activity using Visual Basic 2008. I want to create a small utility to simulate an LED in the system tray for drive read/write activity. I've found several such utilities that do this, but they all lack one thing or another, or they are over bloated with stuff I don't want or need, etc. I want to write my own so it will be like I want it. To get started, I need to know how to monitor drive activity. Can anyone point me in the right direction?
Blessings
