Yes i want to embed a combobox in a listview so that i select items directly from listview For example In an order filling form .
|
|
|
|

I doubt you can do that. A datagrid may allow you to do that, I'd give that a 95% chance of being the case.

Is there a single command that will tell me if an Array = nothing i.e. no data in array
This would be a 2 dimensional array. What I am looking for is something list this
If Array <> Nothing then
****do something
else
****do something else
endif
|
|
|
|
|
(In .NET) You are right about the <> Nothing part, but if the array has been initialized then this will not work. You could try If (Array.Length > 0 Then), this will tell you if anything is in the array if it has already been initialized.

Hi
Could anyone help me with a small problem. I am trying to print using vb.net. I can use the following line of code to print using vb6.
Printer.Print "Reference No.: " & frmWorkOrder.txtFindWO.Text
How do I do the same in VB.net
Thanks

Is it possible to simulate the following key press sequence in a VB program.
Sequence <alt> <prnt scrn="">
i.e. so it acts as if these keys were actually pressed.
Thanks,
|
|
|
|
|
The sequence was ALT PRNT SCRN, but used angle brackets so not show in original post.

hi , can anyone help me please?
i'm new to the vb.net
i want to download web pages from the web into local files , i used URLDownloadToFile from the microsoft site :
Private Declare Function URLDownloadToFile Lib "urlmon" Alias "URLDownloadToFileA" _
(ByVal pCaller As Long, ByVal szURL As String, ByVal szFileName As String, _
ByVal dwReserved As Long, ByVal lpfnCB As Long) As Long
Dim llRetVal As Long
llRetVal = URLDownloadToFile(0, "http://www.yahoo.com", "c:\Temp.htm", 0, 0)
but nothing happened .
why?

You used the declaration for VB6, which won't work in VB.NET because the type names are now different sizes. By this, I mean that in VB6, a Long is a 32-bit signed integer. In VB.NET, the Long type is a 64-bit signed integer. The declaration should be:
Private Declare Auto Function URLDownloadToFile Lib "urlmon" _
(ByVal pCaller As IntPtr, ByVal szURL As String, ByVal szFileName As String, _
ByVal dwReserved As Integer, ByVal lpfnCB As IntPtr) As Integer
You'll call this with:
Dim returnCode as Integer
returnCode = URLDownloadToFile( IntPtr.Zero, "http://www.whatever.com", "C:\MyDownloadedStuff", 0, IntPtr.Zero )
I don't know if it'll work exactly like this because I haven't tried it...

Are there any ways to delete a directory that is NOT empty? (In Vb.Net)
I used System.IO.Directory.Delete, but the directory has to be empty..
|
|
|
|
|
Or are there other ways to delete a folder that is NOT empty as well?
|
|
|
|
|
If your supply the Directory.Delete method with the name of the directory and True, it'll delete everything inside the directory you want to kill off.
System.IO.Directory.Delete("C:\TEMP", True)
will delete C:\Temp and everything inside it.

Don't you just use SQL to add a record ?

You need to pass a string in here, you're passing in x, which is also the name of the variable you're trying to create.

Hi,
Can someone please help me in understanding why this code will not work in visual basic .net 2003 ?
I have generated a text file from an access database and I'm trying to read it with my program so hopefully I can manipulate it and write it back to a file. I am having issues with textfieldparser it doesn't appear to exist. Is there an easy way to do this? A working example with a simply txt file would be wonderful or a very step by step tutorial on a website. Thanks for your time.
[code]
Private Sub MenuItem1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MenuItem1.Click
Dim oFileDlg As New OpenFileDialog
If oFileDlg.ShowDialog() = DialogResult.OK Then
Dim sr As New System.IO.StreamReader(oFileDlg.FileName)
MessageBox.Show(oFileDlg.FileName)
sr.Close()
End If
Dim reader As Microsoft.VisualBasic.FileIO.TextFieldParser
reader = My.Computer.FileSystem.OpenTextFieldParser _
("C:\TestFolder1\test1.txt")

reader.delimiters = New String() {","}
Dim currentRow As String()
While Not reader.EndOfData
Try
currentRow = reader.ReadFields()
Dim currentField As String
For Each currentField In currentRow
MsgBox(currentField)
Next
Catch ex As System.Text.Parsing.MalformedLineException
MsgBox("Line " & ex.Message & _
"is not valid and will be skipped.")
End Try
End While
End Sub
