BitConverter.GetBytes() accepts only several types. It seams that the type that you are substituting T with cannot be expected by BitConverter.GetBytes(). Msdn has more information about this function

Thanks for the response
However this I understand, but I was hoping to overcome the need to duplicate a function for each type that I need to add to the bit array. Hence the attempt with Generics.
My understanding is that the type T will become what ever T i pass in to it!
Is the problem because the base function will only accept 9 types and generics potentially means that far more types could be passed in??

Yes, T will become the type that you pass but GetBytes can accept only 9 types. So either the type of T should be one of them or you should write a new class like that acts like bitconverter and has a function called GetBytes that accepts many types but that means quite a lot of work
|

|

Is it possible to limit the types that T can become??

Yes you can by adding the where clause and specifying the restriction you want to apply but I'm not sure if you can limit T to only those nine types. For the constraint that you can apply have a look at this: Types of generic constraints[^]

Is there a C# programming question in the post somewheres I missed? If not, you are in the wrong forum. General Discussion Forum might be better.

You need to be more specific.

Hi all
I want to make a very basic rythm game in c#. What would be the best way to get the grahics to run in time with a music file? Some basic ideas of how it could be done would be great to get me started.
thanx
|
|
|
|

The easiest and most accurate would be to simply use known music and store the time offset and duration of the beats for each song.
To use it with any music, you would typically do fourier analysis of the music waveform to detect patterns in the intensity at different frequencies.

You obviously know what your talking about but sadly i had no idea ... any chance you could break it down a bit for me (which music file is best to use?, how do i find the beat durations? etc.)
I was thinking of having an editor and plotting the notes on a timeline ... saying that I dont think there would be another way to do it!
Thanks for your response

how can i store this values into array
|
|
|
|
|
Create an array with the same length as the number of records. Loop through the records and copy the values into the array.
How you loop through the records depends entirely on how you fetch the records from the database.

this is the function written in javascript to load pictures.
function loadPics()
{
pic0=new Image();
pic0.src="1.jpg";
pic1=new Image();
pic1.src="2.jpg";
pic2=new Image();
pic2.src="3.jpg";
pic3=new Image();
pic3.src="4.jpg";
pict=new Array();
pict[0]=pic0.src;
pict[1]=pic1.src;
pict[2]=pic2.src;
pict[3]=pic3.src;
}
i retrive the image src from database and stored it in the array like this..
try
{
if (con.State != ConnectionState.Open) con.Open();
cmd.Connection = con;
cmd.CommandText = "select varImageSrc from mtblGallery";
dt.Clear();
ada.SelectCommand = cmd;
ada.Fill(dt);
recCount = dt.Rows.Count;
string[] imgArray = new string[recCount];
for (i = 0; i < recCount; i++)
{
imgArray[i] = (dt.Rows[i][0].ToString());
}
if (con.State != ConnectionState.Closed) con.Close();
}
and now my problem is how can i load the imagesrc from this imgArray to the javascript function to make the loadPics() function dynamically load the images.
can anyone help.. its urgent.
thanks in advance

Hi All,
I am facing two problems while accessing the Sharepoint server URL using HttpWebRequest/HttpWebResponse.
Sample Code:
try
{
string Url = "http://<sharepoint server>/<site>/<docment library>;
Uri destUri = new Uri(Url);
HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(destUri);
CredentialCache cache = new CredentialCache();
cache.Add(req.RequestUri, "Negotiate", new NetworkCredential(strUserName, strPassword, strDomain));
cache.Add(req.RequestUri, "NTLM", new NetworkCredential(strUserName, strPassword, strDomain));
req.Credentials = cache;
HttpWebResponse ores = (HttpWebResponse)req.GetResponse();
ores.Close();
if(ores.StatusDescription.ToLower() == "ok")
{
MessageBox.Show("Success");
}
else
{
MessageBox.Show(ores.StatusDescription);
}
}
catch (WebException we)
{
MessageBox.Show("Web Exception : " + we.Message);
}
catch (Exception ex)
{
MessageBox.Show("General Exception : " + ex.Message);
}
Issue #1:
I have created the folder inside a folder under sharepoint document library(ex: DocumentLibrary\Folder1\Folder2)
Using the above code I am testing the connection, it returns Success up to Folder1(ex: http://<server>/<site>/DocumentLibrary/Folder1)
I am trying the add the Folder2 in URL, It returns web exception UnAuthorized for the same credential.(eg: http://<server>/<site>/DocumentLibrary/Folder1/Folder2)
Issue #2: If there is any space in document library name, it returns web exception "Bad URL"
(eg: http://<server>/<site>/Shared Documents)
Can any one know how to fix these problems?
Thanks
Ram

Please if someone can explain if this can be done/how it is done :
I want my program to automatically click a link for a website and then save the file with the defualt program that is assigned to it.(not my program)
For example, if the user writes "nero", I enter a search site that I choosed before, and I want it to click the first result that comes from the website's search engine, and afterwards to click open. (for example in my computer if I click open it will be downloaded with flashget/azuereus depends)
simply go for the defualt.

You may want to use winapi calls to simulate user clicks, but it will be very strongly coupled with the browser you choose. Why don't you just open a connection with the search engine you are using, and talk to it as though you are the browser. That way, all the data will pass through your code with no middleman. Then if you want to display what you found, you can open a third party application at that time with the file you saved to the hard drive.

How can I do that? I'm new to this stuff and I'm still learning.
How can I simulate user clicks?
and more important how can I open connection with search engines??
|

Here is an example to Simulating User Clicks. Just use the methods "GetWindowHandleWhoseTitleStartsWith" and "SimulateClick". The problem with this approach is that the external application must be active (I think) and visible (I think). Also, you develop a hard dependency between the location of buttons in your application and the third-party software, which is terrible practice. The alternative method I suggested is DEFINITELY the preferable way to do it, but I cannot give you an example because I have not used sockets or HTML communication in C#. Basically, the idea is that you would open a socket connection on the standard html port at the destination (probably some call like Socket s = new Socket("http:\\www.google.com", 54), send an html request to get the search page (probably like s.SendMessage(new HTMLRequest("http:\\www.google.com#searchstrings"))), then parse the return HTML to get the first link (see xmldocument or htmldocument), and finally load the data from that link into your own HTML browser. You will have to do some work to figure that out, but it will ALWAYS work and does not depend on third-party software (other than the search engine). Sorry I couldn't be more help in that arena.
private IntPtr m_Handle = IntPtr.Zero;
public delegate bool EnumWindowsProc(IntPtr handle, object data);
[DllImport("user32.dll")]
public extern bool EnumWindows(EnumWindowsProc proc, object data);
[DllImport("user32.dll")]
public extern int GetWindowText(IntPtr handle, StringBuilder title, int maxSize);
[DllImport("user32.dll")]
public static extern IntPtr SendMessage(IntPtr handle, uint op, uint keys, Point point);
public IntPtr GetWindowHandleWhoseTitleStartsWith(string title) {
m_Handle = IntPtr.Zero;
EnumWindows(myEnumWindowsProc, title);
return m_Handle;
}
private bool myEnumWindowsProc(IntPtr handle, object data) {
string searchTitle = data as string;
if (searchTitle == null)
return true;
StringBuilder title = new StringBuilder();
GetWindowText(handle, title, searchTitle.Length + 1);
if (title.ToString() != searchTitle)
return true;
m_Handle = handle;
return false;
}
public void SimulateClick(Point pos, IntPtr handle) {
SendMessage(handle, (uint)WM_MOUSEDOWN, 0, pos);
SendMessage(handle, (uint)WM_MOUSEUP, 0, pos);
}

Hi
I want to use a Windows Service to call certain stored procedures once a day.
It needs to pass the DateTime.Now as a variable to these stored procedures.
If someone could please help me out as to how i implement a timer and call stored procedures and pass the current datetime to the stored procedures.
Thanks
|

|

You can initialize a variable of System.Threading.Timer in the OnStart method as set up event handler for Elapsed event. In the event handler call the stored procedure using sqlcommand object and pass the parameter by adding it to Parameters collection
