The first post gets the point of reading input... from the mouse. I might implement it somewhere else, so thanks anyway. The second post is a little bit more close to what i need... definitely will take a look. I'll post results when i try it

Ok. So.

I'm trying to develop an application to capture the input buffer to identify a device's input commands to build a user control that uses this commands for further use.

I'm actually developing a project that simulates Guitar Hero, and I want it to recognise the Guitar Hero Controller's input.

I know there are already several controls that work with the guitar hero controller. The thing is i MUST develop this control myself.

What i've done so far only recognises input from the keyboard using Console.OpenStandardInput() . The thing is, as the class name says, it reads input from the Console... not from all sources possible, such as mouse, and other peripherals (joystick, and as i need it, Guitar Hero Controller)

Here's my code:

Sub Main()
        Dim Data As System.IO.Stream
        Dim buff(32) As Byte
        Dim buffOut() As Byte
        Data = Console.OpenStandardInput()

        'Dim DataBuff As System.IO.BufferedStream
        'DataBuff = System.IO.BufferedStream.Synchronized(Data)
        Using memoryStream As New System.IO.MemoryStream
            Dim count As Integer
            Do
                count = Data.Read(buff, 0, buff.Length)
                MsgBox(buff.GetValue(0))
                memoryStream.Write(buff, 0, count)
            Loop While count <> 0
            buffOut = memoryStream.ToArray()
            Debug.Print(buffOut.ToString())
        End Using
    End Sub

I guess (since i don't really know) all i need is guidance towards the right input buffer to use for this purpose, since the Console Input Buffer is not working for me.

Thanks in advance!!

Actually, i'd rather choose a portable hd... since they come in sizes such as 100 Gb, which is 3 times bigger than dell's flash drive, and, as well, cheaper... so... taking the theory of Infarction, which says, install an OS in 10 Gb, you still have 90 Gb left for whatever you would like...

So... i don't know u guys, but i would prefer buying a 100 Gb portable hd...

Hi guys...

you see, not a long time ago, my computer worked fine... absolutely fine... about a week and a half in, something odd started happening... when i play any flash embedded games online (say... facebook), after a while (when the game gets too loaded) my pc goes berzerk, moving my cursor all over the screen and making beeping error sounds, to finally crash and shut down... any ideas?

Solved... thanks!

I knew i was close when i thought about IDictionaryEnumerator... now... should i use IDictionary or Dictionary

Hi all. Is there any collection object that will let me create a list of items which I could call by name, instead of by number? so instead of soing this:

//Create List
List<ClassType> list = new List<ClassType>();

//Assign values to list
list.add(new ClassType(params, [params, [params]]));

//Call list items
list[0].method();
list[1].method();

i do this:

//Create List
List<ClassType> list = new List<ClassType>();

//Assign values to list
list.add(new ClassType("id", [params, [params]]));

//Call list items
list["id1"].method();
list["id2"].method();

I have a query manager class which has a string for every table, in order to call just the tables i need, so, by calling the List items by id makes the association easier, since i assign an id for the table, as much as for the List item referencing the table.

Thanks

so, after reviewing some notest on SQL connections for c#, here's the final code...

string conStr, cmdStr;
conStr = "--Copy Connection String Here--"
System.Data.OleDB.OleDBConnection con = new System.Data.OleDB.OleDBConnection(conStr);
cmdStr = "Delete YourTable Where ID_Primary_Key = ?"
DataRow row;
int rowcount, registryID;
rowcount = YourDatabaseDataSet.YourTableName.Rows.Count;
for (int i=0;i<rowcount;i++)
{
    row = YourDatabaseDataSet.YourTableName.Rows[i];
    for (int j=0;j<rowcount;j++)
    {
        if(row == YourDatabaseDataSet.YourTableName.Rows[j])
        {
            registryID = Int32.Parse(YourDatabaseDataSet.YourTableName.Rows[j].ItemArray[0].ToString());
            using (System.Data.OleDB.OleDBCommand cmd = new System.Data.OleDB.OleDBCommand(cmdSTR, con))
            {
                cmd.CommandType = CommandType.Text;
                cmd.Parameters.AddWithValue("ID_Primary_Key",registryID);
                con.Open();
                cmd.ExecuteNonQuery();
                con.Close();
            }
            rowcount--;
        }

my bad... it's your DataSet... so it represents the DataSet created by c# when you add a datasource

that is because detailsAdapter is not a DataTable, its a TableAdapter. What you should do is, instead of reading a DataTableAdapter, reading a DataRow and run a nested for loop within another for loop, gather the information from the outer's for loop index row and compare it to the rest of the table. That way you remove the duplicates in the table, and you can update the database using a sql query. What database areyou using?

the nested for loops would go something like this:

DataRow row;
DataTable table;
int rowcount;
table = yourDataBinding.yourTable;
rowcount = yourDataBinding.yourTable.Rows.Count;
for (int i=0;i<rowcount;i++)
{
    row = yourDataBinding.yourTable.Row[i];
    for (int j=0;j<rowcount;j++)
    {
        if(row == yourDataBinding.yourTable.Row[j])
        {
            table.RemoveAt(j);
            rowcount--;
        }
    }
}

this is no place for us to do your homework... why don't you check your notes and come back later?

char ch;
string str1,str2;
int num;
num = str1.IndexOf(ch);
str2 = cadena.Substring(num);

actually, computers are neither men nor women... they're machines, so... where am i supposed to place my vote?

sounds like you could use some ajax or javascript, since html is much of a static code: once it's loaded, you can't change it.

What you want to do is dynamically change the content of a Javascript string variable contained in the paragraph in question, so when the user clicks on an image, javascript assigns that variable the string desired (in this case, your paragraph).

if you want your whole background to be black, why don't you style the body instead?

<style type="text/css">

body
{
    background-color: #000;
}

</style>

Yes it is.

Anything else?

why don't you try MySQL?

can Swing run on web applets though?

What are the differences between both and which one should i consider for the different kinds of java-based apps?

you should make your det_max function an int instead of a void fucntion, returning the max value and assigning it to the max variable in yourmain function... like this:

int det_max(int yards, int max)
{
   if(yards>=max)
      return max;
   else
     return yards;
}
...
int main()
{
...
max=det_max(yards,max);
...
}

the code you have there asks for the name, week and yardage twice: once in the main function and a second time in the showRByards before showing the stars... maybe you should try removing it from the main function.

great, thanks!!

Hello...

is there any way of making java listen or capture an F-key input? i mean, like, if the user presses F5, a new panel will come up and that sorts of things...

thnx

k... so, here's the thing...

I'm creating a User's Interface to insert some data into a database, and there are some fields that have foreign keys to other tables, which i have listed in a <SELECT> form, so the user would just select the vlue from a list instead of inserting a new one, which might cause some trouble with the db's integrity... when i want to insert the value to the table, i must do a subquery to obtain the value that goes into the table... that's where i have the problem... mysql just returns an error telling me i have an error in my MySQL syntax...
here's the code for 'insertar.php':

<?php
if($_POST['submit_region']){
   if(mysql_query("
      INSERT INTO Region (Nombre, Cod_Pais)
      VALUES ('$_POST[nombre_region]', (SELECT Cod_Pais FROM Pais WHERE Nombre=$_POST[opcion_pais]))", $cos_s)){
      echo "Fila insertada en la tabla 'Region' existosamente<br />";
   }else{
      die("Error al insertar registro en tabla 'Region'<br />" . mysql_error());
   }
}
?>

and this is the code for 'insertar_datos.html':

<form action="insertar.php" method="post">
   Nombre de la Region: <input type="text" name="nombre_region" /><br />
   Pais de la Region: <select name="opcion_pais">
      <option>--Seleccionar Pais--</option>
      <?php 
         $resultado_pais = mysql_query(" SELECT * FROM Pais ORDER BY Nombre");
         while($row = mysql_fetch_array($resultado_pais, MYSQL_ASSOC)){
            echo "<option value=\"" . $row[Cod_Pais] . "\">" . $row[Nombre] . "</option>";
         }
      ?>
   </select><br />
   <input type="submit" name="submit_region" value="Insertar Region">
</form>

this is the output: Warning: mysql_query(): supplied argument is not a valid MySQL-Link resource in /home/www/lapuglia.awardspace.com/insertar.php on line 21

Hi silverside,

ever occurred to you we're not here to do your homework for you??

actually i don't know what happened... honest... the only thing i changed before reloading was changing the defaul font to arial... but, after noticing it was fixed, i changed it back again, and, voila!

dunno what happened, but it's fixed now... :D

they're not actually unmuted... but it won't let me raise their volume

all of them are unmuted except for Mic Boost , Optical Raw , Audigy Analog Output Jack , and External Amplifier

why not copying the documentation into a txt file?

it's no good using WYSIWYG html editors, because they turn your site into something less functional than what it should be...

though, if you want you can check out trial versions for coffee cup, or dreamweaver... i suggest trial versions since, as it is obvious, you don't need it for professional html editing, but just to come out of the rush... if you were truly interested in designing a site, you should get your hands in a html and css tutorial...

well, installing truetype fonts didn't fix the issue...

that's the lspci output...

will this mess up my HDD?

how specific do you need it? with hexadecimals and everything?

As i said on my other post, i recently installed Ubuntu 7.10 in my desktop computer... i have two HDD's, a master and a slave... before formatting my pc to install ubuntu, i moved some information from my master to my slave. But, when i tried to access my second HDD, it sends the message in the picture. It is fully recognized, and it even show's me the hardware details... but it won't let me access it, and i have very important information there... i was thinking extracting the information in a friend's computer, but it would be better if i fix the problem in my computer...

I recently changed my Desktop PC from Windows XP to Ubuntu 7.10 (yay for me!), but, i had several issues... one of them (the less urgent) is that my Creative Audigy SoundBlaster 0090 doesn't show any signs of life... though, the interesting part is that it is fully installed and fully recognized by ubuntu... i've tried installing every related package, including the ALSA related, but nothing works... so any help would be appreciated...

k... i'm on it

well, i'll try changing my browser's settings to other apart from the default ones, but i don't think it'll change anything. What about the gray boxes' rounded corners? They shouldn't be affected by the font's size...

@ Midimagic I haven't changed anything in my computer from its default settings... nor played any fullscreen games (actually i've played only the ones packed with ubuntu) so... i don't know...

yeah... that's not the problem... i tried Ctrl + 0 and no change... i even zoomed in and out, and same response...

here's a better look at the thingies...

not so long ago, i changed my desktop from Windows to Ubuntu... this is actually the first time i log in to DaniWeb since then, and then... it happened... i'm running mozilla, and it's rendering the gray boxes around some items in a very odd way... take a look at the screenshot.

Also, the LOGOUT button from the user's navigation menu, in the upper side of the page is in a new line, not with the rest of the buttons... probably these two rendering errors are caused by my desktop's resolution, but, either way, it shouldn't do that, right?

a syrup container in use? the top left part is the base, and the tip, is... the tip

a microwave?

found out where my problem was (besides that one)... thank you...

let me see... so, what you want to do is the list to appear directly below the tabs, or a hover menu to appear when you hover the tabs?
