I was wondering if this was possible....i know i can use a VB Variable in javascript using <%= strRandom %>. But it doesn't seem as easy to pass a javascript variable to a VB variable.

You can't. They are two entirely different runtimes that don't know anything about each other and provide no methods for communication between them. What you're doing in your code example is actually replacing the <%...%> tag with the value of the variable in the HTML. The Java code doesn't even know VBScript exists.

Yeah, I just used a hidden object to store the value and take it from that.
But thanks for the reply

I have a question... I have a datagrid populated with a large list of information. I have a text box above the datagrid and i want it to be possible for the user to click inside the textbox and type a letter and the list jumps to the row on the datagrid beginning with that letter. As the user continues typing in letters it brings matches up to the item on the list that most closly matches what is being typed.
The way I have it now is that the user can type in a word and it finds that row in the datagrid. I want it to match up to the letter. any clues?
This code is what i have now...it finds the item by number or acronym typed in the text box but you have to type in the whole number or acronym...not just one letter.
Private Sub txtSearch_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtSearch.TextChanged<br />
Dim intItemFound As Integer<br />
This will search the programlist for whatever the user is inputting in the textbox<br />
If Me.rbAcronym.Checked = True Then<br />
intItemFound = Me.m_bndProgramList.Find("REVISION_ACRONYM", txtSearch.Text)<br />
Me.m_bndProgramList.Position = intItemFound<br />
ElseIf Me.rbNumber.Checked = True Then<br />
intItemFound = Me.m_bndProgramList.Find("BASE_PROGRAM_NUMBER", txtSearch.Text)<br />
Me.m_bndProgramList.Position = intItemFound<br />
End If

The Find method doesn't support wildcards and will match onlt the entire search string, case-insensitive.
If you want to narrow down what the user sees, then you can use the Filter property of the BindingSource and use something like:
Me.m_bndProgramList.Filter = String.Format("REVISION_ACRONYM LIKE '{0}%'", txtSearch.Text)
This will return all of the records that have a value in the REVISION... column that starts with the text entered in the TextBox.

I have a series of windows that have windows inside and I wish to lock them together so if the outer window is expanded the inner window will follow.
|
|
|
|
|
Handle the Resize event of the outer window. In there, calculate the new size of the child windows appropriately for your situation and set the Size property of the child windows.
|
|
|
|
|
Do you have an example of this.....
|
|

Dude, seriously?
Look, I remember being a beginner too but when someone tells you what to do you really need to have the where with all to go figure it out form there.
If we do it for you then you will not learn anything.

HI all,
I want to declare dyanaic arrays.How can I. I am trying like this but it is giving error ?
Dim Names() As String
Sub New(ByVal st As List(Of String))
st.CopyTo(Names) <-- value cannot be null error
End Sub
How to solve this
Thanks in Advance

I believe your problem is you haven't created your Names array yet.
So I think your code should be something like:
Dim Names() As String
Sub New(ByVal st As List(Of String))
if Names is nothing then
Names = new String(st.Length)
end if
st.CopyTo(Names) <-- value cannot be null error
End Sub
Anyway, hopefully you get the idea.

Thanks Ben,
But it is giving RunTime Error.Becuse these method (Names = new String(st.Length)) is not supported in Vb.net
Dana
|
|
|
|
|
Ok try this:
private Names As String()
Sub New(ByVal st As List(Of String))
st.CopyTo(Names) <-- value cannot be null error
End Sub

It doesn't work because the Names array doesn't have any elements in it. If you delcared the array as:
Dim Names(10) As String
it would contain 11 elements of type String, all with the value of String.Empty.
The way you've done it, there are no elements in the array. You'd have to ReDim the array to the proper size, then call CopyTo
Sub New(ByVal st As List(Of String))
ReDim Names(st.Count - 1)
st.CopyTo(Names)
End Sub
But, I highly recommend changing the array to a List.
Private _names As List(Of String)
Public Sub New(ByVal st As List(Of String))
_names.AddRange(st)
End Sub

Thanks Dave.....
It worked well

I'v created a report in visual studio using crystal reports.
And everything works fine as long as I test it on a machine wich visual studio installed.
Otherwise I get a error and the prog closes.
Ok so I went and googled this problem and found out that I need to install 'crystal reports for .net' onto the test machine.
The problem I have now is I can't find a download for this.
On the site of business objects I'v found information about this but it doesn't tell me wether or not I need to buy something or if it's a free download, or were I can download it.
http://www.businessobjects.com/products/reporting/crystalreports/net/vsnet.asp[^]
does anyone know if I need to buy one of there products and so wich one. The embedded crystal reports in visual studio is suficiant for me so all I need now is to be able to deploy it to another machine.
thanks in advance

[SOLUTION]
after a long search I'v found a possible solution
adding a merge module to my setup project appears to have solved the problem
since I had to search a very long time to find it here is a link in case anyone has the same problem:
http://support.businessobjects.com/downloads/merge_modules.asp[^]
the downside to this solution is that every time you install the programme this module is installed aswel (wich takes a bit longer) also the programmes size increases alot and the build time voor the setup project is alot longer.
But it works

You should be asking this in the ASP.NET forum.

I am developing a web application in that I need to record audio, for that I am importing "winmm.dll" and
using mciExecute function.(the following code is in vb.net). If I have posted in irrelavent forum please let me
know where should I post questions related to audio and video (for web development).
<code>
Imports System.Runtime.InteropServices
Imports Microsoft.VisualBasic
Imports Microsoft.VisualBasic.Devices
Partial Class audioRec
Inherits System.Web.UI.Page
<DllImport("winmm.dll", EntryPoint:="mciExecute", CharSet:=CharSet.Ansi, SetLastError:=True,
ExactSpelling:=True)> Private Shared Function mciExecute(ByVal lpstrCommand As String) As Boolean
End Function
Protected Sub BtnStart_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles BtnStart.Click
mciExecute("open new Type waveaudio Alias recsound1")
mciExecute("set recsound1 time format ms bitspersample 16 channels 1 samplespersec 8000")
mciExecute("record recsound1")
End Sub
Protected Sub BtnStop_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles BtnStop.Click
mciExecute("save recsound1 c:\\record.wav")
mciExecute("close recsound1 ")
Dim c As New Computer
c.Audio.Stop()
End Sub
Protected Sub BTNplay_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles BTNplay.Click
Dim computer As New Computer
computer.Audio.Play("c:\\record.wav", AudioPlayMode.Background)
End Sub
End Class
</code>
but when I am clicking the start button, A msgBox with "the parameter is out of range " msg is getting displayed. I need to to record an audio file in "8khz, 16 bit, mono" format. If I change the value of samplespersec to 11025 or greater frequency it works. But I am not able to save my audio file in 8kHz format.
How can I meet this requirement.
i will be thankful for ur suggestions..
with regards,
kiran

The code you've come up with is never going to work. Any ASP.NET code you write in VB.NET or C# or whatever only executes on the server-side.
You need an ActiveX control installed on the client-side and usable in your HTML page that your ASP.NET code generates in order to get at the hardware on the client. Your VB.NET code will have nothing to do with this.
This is a question best asked in the ASP.NET forum.

help I need to map from the server to the local host.
I am having problems with my web application, i am unable to make the application read on the hard drive of the client (local) machine, i need to be able to map the path such that this application is able to upload files from the client's C:\ drive.
Any ideas....it's a VB.net application running on a web server.
thanks,

An ASP.NET website cannot access resources on the client machines that are accessing it, nor should it for security reasons. It simply provides a means for producing MIME-encoded data streams that can be handled by a web browser.
If you need to provide the facility for the user to upload a file from their local machine, create a page with a FileUpload control on it. The user will need to pick the file to upload of course.
