How to play WAV file from resource ???

Hi,
you can try the code below
using System;
using System.Runtime.InteropServices;
using System.Resources;
using System.IO;
namespace Win32
{
public class Winmm
{
public const UInt32 SND_ASYNC = 1;
public const UInt32 SND_MEMORY = 4;
// these 2 overloads we dont need ...
// [DllImport("Winmm.dll")]
// public static extern bool PlaySound(IntPtr rsc, IntPtr hMod, UInt32 dwFlags);
// [DllImport("Winmm.dll")]
// public static extern bool PlaySound(string Sound, IntPtr hMod, UInt32 dwFlags);
// this is the overload we want to play embedded resource...
[DllImport("Winmm.dll")]
public static extern bool PlaySound(byte[] data, IntPtr hMod, UInt32 dwFlags);
public Winmm()
{
}
public static void PlayWavResource(string wav)
{
// get the namespace
string strNameSpace=
System.Reflection.Assembly.GetExecutingAssembly().GetName().Name.ToString();
// get the resource into a stream
Stream str =
System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream( strNameSpace +"."+ wav );
if ( str == null )
return;
// bring stream into a byte array
byte[] bStr = new Byte[str.Length];
str.Read(bStr, 0, (int)str.Length);
// play the resource
PlaySound(bStr, IntPtr.Zero, SND_ASYNC | SND_MEMORY);
}
}
}
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::;
To use the class, you can make the call as follows:
private void button2_Click(object sender, System.EventArgs e)
{
Win32.Winmm.PlayWavResource("chimes.wav");
}

Hi,
may i know how to disable alt+tab and windows key for my application?

If that's possible at all, it requires a system wide keyboard hook. There are articles on CP on how to do this, but I'm not sure if it will work. If not, then it's not possible.

Yes It is possible. You will definitely need a System Wide Hook.
Which version of VB are you using ¿
In VB 6, you will need to use the SystemParametersInfo API. You can implement it like this :
Private Declare Function SystemParametersInfo _
Lib "user32" Alias "SystemParametersInfoA" _
(ByVal uAction As Long, ByVal uParam As Long, _
ByVal lpvParam As Any, ByVal fuWinIni As Long) As Long 'API Function to disable keys
Private Sub DisableCtrlAltDel(bDisabled As Boolean)
' Disables Control Alt Delete Breaking
'as well as Ctrl-Escape
Dim X As Long
X = SystemParametersInfo(97, bDisabled, CStr(1), 0)
End Sub
Then the call to the Above function :
Private Sub Form_Load()
Call DisableCtrlAltDel(True) 'disable the system keys
End Sub
'Remember to Enable the system keys again, when the program exits, otherwise it will remain blocked. To re enable them, Just supply False to the DisableCtrlAltDel function.
With VB.NET it is a bit more difficult. Luckily there is a component called mclhotkey, which will give you the functionality of a System Wide Hook. You can find that component here :
http://www.codeproject.com/useritems/mclhotkey.asp?print=true[^]
Hope that helps!

Hi,

"end for" can break a for loop.
but how to continue a for?
for example:
For i =0 to 10<br />
if(i =4)<br />
continue<br />
Response.write(i)<br />
Next
the result should be:
012356789
But how to do it in vb??

That looks like perfectly good VB to me, except that I thought you needed 'then' and continue on the same line, unless you put end for.
Another way would be
if (i<>4) then Response.Write(i)

Hmm, isn't that Exit For ¿¿

If you have a textbox named Text1 in your form(VB), then this will do the job
For i=0 To 10
If i=4 then
GoTo ss
End If
Text1.Text=Text1.Text & i
ss:
Next

I need to fix an installation problem. I have created a setup programm using MS Windows Installer. My project involves VB6, Crystal Report 9 and SQL server 2000. I have used merged module. Setup is built successfully showing no error. I need to run the setup in user computer using admin previlege. It installs and runs successfully in admin previlege login. But when user(doesn't have admin previlege) logs in the computer and tries to use programm, gets runtime error showing message which says like msdatgrd.ocx or one of its dependencies are not registered correctly. When this user is given admin previlege the software runs nicely. Same thing happens for mscomct2.ocx. I need help in this regard urgently.

iam doing a project in vb.net (winforms) .I have a timespan variable which has a start time and a frequency.this is saved in the database.the field for time is defined as char(this is a must, i can't use datetime or timestamp for storing a time value)
I have a click event on a button called 'view', where a display form should come in which this start time is shown for 24 hrs, each time the frequency is added to the previous one.
For example if the start time is 06.00 and the frequency is 1 hr, then the display form will show from first 06.00 and then one hour added to it , ie 7.00..like this it is shown for 24 hrs from teh start time.
If the frequency is quarterly then 15 minutes is added to each time starting from the start time.
there is no date associated, only time.
So what should i use for this.
For houlry basis I tried using a timespan variable.but when the adding continues, once it reached 23 hrs then it goes to 1.00:00, 1.01:00, 1.02:00 etc etc..instead of 00:00, 01:00, 02:00 respectively
what should be done.please help.it is very urgent.
thanks
chepps.

Why can't you use a datetime or timestamp?
What is your code for incrementing this value?
Steve
|
|
|
|
|
i have used a timestamp variable only
if temp is that variable
then my code will be
temp = temp.Add(TimeSpan.FromHours(1))
this is in a loop for 24hrs.This is showing correctly till 23:00.
Chepps

You could try something like this:
Dim duration As System.TimeSpan
duration = New System.TimeSpan(0, 1, 0, 0)
Dim temp As System.DateTime
'Initialise temp here
temp = temp.Add(duration)
or you could just use:
Dim temp As System.DateTime
'Initialise temp here
temp = DateAdd("h",1,temp)
You will have to place the Dim's & methods in the appropriate place for your loop.
Hope that helps...

I tried this now.Inbetween i got an error.before going deep into the error, i just tried using temp as datetime variable as you suggested rather than a timestamp variable and tried this
temp = temp.Add(TimeSpan.FromHours(1))
and while displaying i suppressed the date part in temp as;
Dim ShowTime As String
ShowTime = FormatDateTime(temp, DateFormat.ShortTime)
and it worked!!!!Thanks a lot.
thank you for the suggestion. i was held up in this for such a long time, by using a timestamp variable and not trying any other options.
Thank you.

Great! Glad I could help.
One thing about the timestamp type is that it has a MinValue and MaxValue property which could have been giving you problems...
Steve

|

OK.i have not gone into that property.will go through.
Thanks a lot for ur timely help

Hello,
working on an app for a buisness...
Now that it's almost done, I'm going threw it again, fixing "details"...
One of those "details" is causing me major problems: pop ups.
I need pop up windows, which I made with the classic JavaScript window.open,
because it's easy to specify all sorts of properties, like no toolbars, sizing...
How can I make those pop ups WITHOUT JavaScript: it gets blocked by recent OS's like xp sp2...
So, pop up windows without javascript, that won't ever get blocked, and where I can specify similar properties as I could with the evil javascript...
(and it's hard to google a solution to this, because 99% of results are javascripts)
Pleeeease help?

You simply use target="_blank" on a link. The page opens in a new window, but you can't specify any properties for how the window should look.
