I have my static RegistryAccess class which reads and sets values in the registry. I want to be able to set/get the value that contains the space (Default) in the registry. However if I access it with key="(Default)" it creates another registry entry with that key value instead of accessing the default registry key.
(In otherwords this is what I see in regedit:
(Default) REG_SZ (value not set)
(Default) REG_SZ true
Do I access it with key = string.Empty ???
Thanks.

How can i make my program to loop for .5 second before moving on to next line of code.
Is it the same as using Thread.Sleep(500)?
Yes, it's running on a thread but i don't know doing that how it's gonna affect other threads.
Appreciate

The whole point of threads is that doing something in one does not affect any others.
So you are right, Thread.Sleep(500) will wait for half a second.

Is there some kind of code to delay .5 seconds instead of using thread.sleep()?

What's wrong with Thread.Sleep?
How about this (untested code):
DateTime start = DateTime.Now;
TimeSpan ts = DateTime.Now - start;
while (ts.TotalMilliseconds < 500)
{
ts = DateTime.Now - start;
}
But that would be silly. Use Thread.Sleep.

Thread.Sleep(500) has only effect on the current thread.
It doesn't have any effect on the other threads.

string query = "Insert Into Users(username,password) values(' + "\"" txtusername.Text "\" ','"\" txtpassword.Text"\"')";
adp1 = new OleDbDataAdapter(query, conn); > firstly, is this correct ?
secondly: how should i change this values(' + "\"" txtusername.Text "\" ','"\" txtpassword.Text"\"') ? it gives error ;( dont know how to modify ?

Once you get it working you really should make a method to go through the textboxes and strip out some characters. Right now you are vulnerable to a sql injection attack.
If I put: bob'; delete * from user; --
I just deleted everything in the user table.

You should never strip out and limit the user´s possibilities. You should escape the characters instead.

Hi,
Does anybody know how to calculate/extract the Pitch values from a Wave (*.wav) file?
Thanks,
Gidon
|
|

Hi!
For this you'll have to perform a fourier transformation.
Basically, your try to approximate the wave form you have by adding many sinus waves. That way you get the volume (amplitude) at certain frequencies, which will ultimately give you the pitch.

Thanks for the explanation.

Hi ,
I succeeded in performing the FFT on my wave file and even printed the results into a nice Spectogram.
But I don't know how to extract the pitch from these values. Do you have any pointers at to what function I need to perform on the FFT data?
Thanks
Gidon

Hi!
I'm afraid I don't have any further pointers on how to calculate the pitch value.
You should be able to get a pitch value by multipyling each frequency with the amplitude for this frequency and summing up the values.
That way you'd get a high value if you have many loud, high-frequency bands and a low value if there are more low-frequency bands.
But I must admit I don't know if that'll suite your needs.

mav

Hi all
How i can to get access to default value or MinValue of an system type.
Or constuct byself an MinValue (or default value) value for each type.
I understand this is possible to make with switch\case but i wont know is exist more convinet way.In run time.
Exmpl:
<br />
<br />
object GetDefaultValue(object SysTypeValue)<br />
{<br />
object defVal;<br />
<br />
......<br />
<br />
return defVal;<br />
}<br />
<br />
void Main()<br />
{<br />
System.Date dt = System.Date.Now();<br />
int i = 100;<br />
char c = 'a';<br />
byte b = 8;<br />
<br />
System.Console.WriteLine(GetDefaultValue(i).ToString());<br />
System.Console.WriteLine(GetDefaultValue(c).ToString());<br />
System.Console.WriteLine(GetDefaultValue(b).ToString());<br />
System.Console.WriteLine(GetDefaultValue(dt).ToString());<br />
<br />
<br />
}<br />
<br />
console:
0
0
0
01.01.0001 0:00:00
THANK

Not sure if the following works, but it should create an instance of passed type by using its default constructor.
object GetDefaultValue(object SysTypeValue)
{
return Activator.CreateInstance(SysTypeValue.GetType());
}

Hi,
i want to check the existence of an integer value in the textbox control with the following code:
if (Convert.ToInt16(tbStockTypeId.Text) <= 0)
works fine when an intger value is entered. but when i enter 'abc' it raises FormatException "Input string was not in a correct format."
Need help for its correction.
With Thanx

First check if the Text value is numeric before trying to convert it.
This can be done with a RegEx, or Char.IsNumeric

thanks for reply! J4amieC
Char.IsNumeric
is fine for a character, while i'm working with textbox string.

try{<br />
int stocktype = Convert.ToInt16(tbStockTypeId.Text);<br />
if(stocktype <= 0) { <br />
}<br />
}<br />
catch(FormatException fexc){<br />
Messagebox(tbStockTypeId.Text + "Is not a number");<br />
}
Coulda, woulda, shoulda doesn't matter if you don't.
