I have something similar handling keypress event of the control, a combobox in my case.
Although not is a "beautiful" code, it works fine enough for my problem, find the first letter entry. I hope you can modify it for your owm problem solution:
Private Sub ComboBoxMacge_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles MyBase.KeyPress
Try
Dim cb As ComboBox = CType(sender, ComboBox)
Dim findString As String = String.Empty
If (Not e.KeyChar.IsLetter(e.KeyChar, 0)) Then Exit Sub
findString = Char.ToUpper(e.KeyChar)
If cb.DropDownStyle <> ComboBoxStyle.DropDownList Then
If cb.SelectedText <> cb.Text Then
findString = cb.Text & Char.ToUpper(e.KeyChar)
End If
End If
Dim IDX As Integer = -1
With cb
Dim ELE As Integer = 0
Dim R As DataRow
Dim DW As DataRow() = Nothing
Try
DW = CType(.DataSource, DataRow())
Catch
Try
DW = CType(.DataSource, DataTable).Select()
Catch ex As Exception
End Try
End Try
If DW Is Nothing Then
Dim s As String
For Each s In cb.Items
' Se distinguen los que tienen codigo o los que no:
Dim idxGuion As Integer = s.IndexOfAny("-")
Dim pos As Integer
If idxGuion < 0 Then ' no hay guion
pos = 0
Else
pos = idxGuion + 2
End If
If s.IndexOf(findString) = pos Then
IDX = ELE
Exit For
End If
ELE += 1
Next
Else
For Each R In DW
' Se distinguen los que tienen codigo o los que no:
Dim idxGuion As Integer = R(cb.DisplayMember).IndexOfAny("-")
Dim pos As Integer
If idxGuion < 0 Then ' no hay guion
pos = 0
Else
pos = idxGuion + 2
End If
If R(cb.DisplayMember).IndexOf(findString) = pos Then
IDX = ELE
Exit For
End If
ELE += 1
Next
End If
If IDX > -1 Then
.SelectedIndex = IDX
e.Handled = True
End If
End With
Catch
End Try
End Sub

I have a problem. I have a report that in design time link with database with an odbc (Oracle provider). In runtime if i don´t change connection it works fine. My problem is that if i change de odbc (i try other odbc with other name but with same dns) at runtime, it doesn´t work.
Only works if i change odbc connection in report at design time...but i need do it programtilly because i need user choose between two equals databases: real and testing.
I try with code like Me.rptDoc.DataSourceConnections.Item(0).SetConnection("ODBCNAME", "", False) and other codes like that:
Dim crConnectionInfo As ConnectionInfo
Dim crDatabase As Database
Dim crTables As Tables
Dim crTableLogOnInfo As TableLogOnInfo
Dim crReportDocument As ReportDocument = Me.rptDoc
crDatabase = crReportDocument.Database
crTables = crDatabase.Tables
crConnectionInfo = New ConnectionInfo()
crConnectionInfo.ServerName = "ODBCNAME"
crConnectionInfo.DatabaseName = ""
crConnectionInfo.UserID = "USER"
crConnectionInfo.Password = "PASSWORD"
For Each aTable As CrystalDecisions.CrystalReports.Engine.Table In crTables
crTableLogOnInfo = aTable.LogOnInfo
crTableLogOnInfo.ConnectionInfo.AllowCustomConnection = True
crTableLogOnInfo.ConnectionInfo = crConnectionInfo
aTable.ApplyLogOnInfo(crTableLogOnInfo)
Next
Could you help me?, thanks in advance

Why would you want to do this? The only reasons I can think of would not be legitimate reasons.

ya OS doesnt allow u to hide ur deamon fron process viewer......

If it runs; It can be cracked!
That's a phrase i saw in a article about protecting software from crackers, and I'll use it here.
(Besides if it's not possible, how is the anti virus software doing it?)
Some time ago i developed a administrative application, and i wanted to implement a feature that would allow the boss to hide the process from the end users 'Task Manager' so they wouldn't kill it.
After some research, i learned that this was only possible with low level Windows API's, something I'm not that comfortable with.
There is basically two main idea's behind this, 1) hiding the process just from task manager, this requires hooking the massages that pass from Task Manager to Windows, then modify the result to exclude your process. 2) install a low level windows driver that monitors the internal windows process list and removes your program's entry.
Needless to say, method 2 is much more effective then method 1 but less stable, and knowledge of C programming is required to develop such a driver.
I hope thats enough info to give you a head's up for what to search for, and i hope your intentions are good ones.
Don't ask me for my results or code, I think if someone really needs to develop such an application he should know a lower level of programming, or be ready to break his head while searching for someone else's code.

My purpose of process hiding is, in my company have some computer that have time period for using so i develop software(VB.NET 2005) for automatic shutdown computer if it has been turn on befor xx:xx A.M. or after xx:xx P.M. and i need to hide this software process from process viewer. But if it can't perhaps i need to hide task manager from end-user.
:-DThank for all suggestion.

I'm using VB 2005 Express, and I'm looking for code that adds images to listview subitems (listview is in report view).
I've found C++ samples, like XListCtrl and Supergrid but I haven't a clue how to interpret them!
Any help much appreciated,

Hi there,
first of all thank you for your help in some of my previous questions. I have been able to work them out thanks to you.
I have one more question.
in my form i have a combobox and a listbox. now in my combobox i have attached the rest_type field of my database (types of restaurants available)
cbrest_type.datasource = dataset11.tables("Restaurants@) <br />
cbrest_type.displaymember = "rest_type" <br />
now if i want to list all the names of the restaurants that are of the same type in my listbox (by choosing it from the combobox), how can i populate it??
ex. i want to list all the restaurants that are al a carte in my listbox...
if you can supply me with code it will be fantastic as i have no idea on how to start :S

Let me give u a arough idea..
1. Bind the resturant type id with your combobox as well like,
cbrest_type.valuemember = "rest_type_id"
2. Get the selectedvalue from the combobox (in SelectedIndexChanged event of combo) to see which rest_type is selected. like cbrest_type.selectedvalue
3. Query the DB for that selected ID to find out the resturants for that ID.
4. Bind them with Listbox.

I have an order table in access.I want to print orders from 1 to 10 or like that.(values entered in two text boxes).I have created the crystal report,it is working smoothly when giving the range values.
But through Vb I wrote
orders.orderid>=value1 and orders.orderid<=value2
If I give value1=5 and value2=7 it is showing properly.I change the the value1 it is working.But if I change the value of value2 it is not refreshing.always the value of value2 remains the first value(the value given for the first time.)

Hi All,
We are porting the following VB 6 code in to VB.net
VB 6 Code:
NumChan = GetDppData(objDppApi, VarPtr(DataBuffer(0)))
Here GetDppData is the function declared as below
Public Declare Function GetDppData Lib "DppApi.dll" (ByVal objptr As Long, ByVal DataBuffer As Long) As Integer
Where DPPApi.dll is a registerable COM Dll.
VB.net code :
UseDll.DppApi.GetDppData(objptr, VarPtr(dp4DataBuffer(intMcaChannelCount)))
Where the above function is declared in a module with name UseDll as below
Public Declare Auto Function GetDppData Lib "DppApi.dll" Alias "GetDppData" (ByVal objptr As Integer, ByVal DataBuffer As Integer) As Integer
VarPtr function Definition in VB.Net is as below
Public Function VarPtr(ByVal o As Object) As Integer
Dim GC As System.Runtime.InteropServices.GCHandle = System.Runtime.InteropServices.GCHandle.Alloc(o, System.Runtime.InteropServices.GCHandleType.Pinned)
Dim ret As Integer = GC.AddrOfPinnedObject.ToInt32
GC.Free()
Return ret
End Function
Here the functionality that we are woking is :
We are passing the Address of array to the dll so that it can fill all the array elements using Base address of the array.
The VB 6 code is working fine.
In the case of VB.Net code array is not getting initialized.
Please Guide me How to proceed
