Refer this one
Sample code is
string printerName ="HP LaserJet M1522 MFP Series PCL 6 (Copy 1)"; // this is my printer name
memoPrintDetail.Clear(); //memoPrintDetail is richTextBox to show my complete printer status later on
memoPrintDetail.AppendText("Printer Name : " + printerName + "\n");
ManagementScope scope = new ManagementScope(@"\root\cimv2");
scope.Connect();
// Select All Printers from my computer
ManagementObjectSearcher searcher = new
ManagementObjectSearcher("SELECT * FROM Win32_Printer");
ManagementObjectCollection collection = searcher.Get();
string filename="text1.txt";
File.WriteAllText(filename,"");
//File.Create("text1.txt");
foreach (ManagementObject printer in collection)
{
//if (printer["Default"].ToString().ToLower().Equals("true"))
//{
// printerName = printer["Name"].ToString();
//}
//else
//{
// continue;
//}
if (printer["Name"].ToString() == printerName)
{
if (printer["WorkOffline"].ToString().ToLower().Equals("true")) // This code is working

memoPrintDetail.AppendText("Status : Offline\n");// This code is working
return;
}
else
{
memoPrintDetail.AppendText("Status : Online\n");// This code is working
}

Hi,
do you host every website in a different application pool? If yes, then you can kill a website by killing the process for the app-pool. I know there is a command-line tool to get the name of the process running a single application pool, so I guess this is also possible using WMI or something similar.

Sebastian

I want to disable print screen on the webpage.
I have tried the option of Clearing the Clipboard after regular interval, issue with this is, it also clears the text data from clipboard
I want to disable only the print screen, whereas user can copy/paste the text data from other windows

I am writing a winform application that allows the user to define a range in a HTML document by selecting two anchor points: beginning and end. I'd like to graphically display the selected range by programattically inserting HTML into the in-memory version of the HTML, which should then render in my WebBrowser control. Ideally, I'd like to draw a box around the selected range, maybe with a nice colored background. Unfortunately, the beginning and ending anchor points may not reside in the same HTML block, and I'm not sure how to write the HTML to make a box span HTML blocks like that.
Clear as mud? Any thoughts or ideas would be appreciated.

I'm working on making tables look nice in CSS, but I'm running into some difficulties:
If I do
td.TD2
{
padding:5px;
}
then I get a class for a single cell with the padding space that I want. However, applying the padding property to a tr class or a table class appears to do nothing.
Anyway, I'd rather not specify a new class for every single td on the page. Is there an elegant way to make the padding property work for an entire table?
|
|
|
|
|
table.T2 td
{
padding:5px;
}
Funny how I tend to figure out the answer to my own question the second after finally resorting to posting on the forum.

(edit: crap, it's in the web forum, wanted to put that in the lounge... possible to move it ?)
Howdy'
Dad wants to have his own presence on the web.
His main use will be to publish fiction and non-fiction texts, articles and stuff like that.
His main requirements are that the layout be as simple as possible (NOT myspace-ish) and that it should be as easy as possible to manage his "site";he also wants to have a domain registered to his name.
I'm pushing him towards blog engine like wordpress or typepad.
Comments ? suggestions ?
Thanks.

Blogspot is a good choice too. If you know html and css, you can change the design to your own.

Anyone telling you the "best" will be giving their opinion, there is no objective winner. I use blogger.com, but wordpress.com and livejournal.com are also popular.

Hi All,
I just want to know which is the best way to retract user of a web page from saving the images displayed in webpage.
The ways I know are
Disable rightclick save image using javascript
Using transparent image in from of the image.
Using flash.
Can anyone suggest the best method for this?
Thanks
|
|
|
|
|
If you want greatest security(of images  ), use flash.
But if you want your site to be compatible as well, then choose 2nd way.
Using flash would be more secure, but not everybody's browser has flash installed.
Therefore I would choose 2nd way.
|
|
|
|
|
Well Yes - We can't expect to have flash on all machines.
Though even if I use second method, the images will be present in the temporary internet file folder.
Any thoughts??
|

That's the way the internet/browsers work.
You put a picture up on a web page then be prepared for the fact that every person that views your picture now has it stored on their own hard drive.
Don't want them to have it don't put it on the internet.

Hi All,
I have a requirement to submit a web page (A.aspx) after filling the details in its field,which need to be done by a Web bot kind of program which will be called when a button click is evoked in my page(B.aspx).
B.aspx page is my page which contains the same fields as there in A.aspx, except that the user won't see A.aspx. When i click the Submit button of B.aspx, the program should fill in the same details in A.aspx and evoke the Submit button click of A.aspx.
Please help me in doing this using C# asp.net 2.0 web application development
Thanks in advance

Hi,
I am developing an application. i have 3 main tables in mysql database . tables are
table1 : products (1000 rows)
table2 : parts
table3 : products_parts (M:N relationship) contains over 40,000 rows with parts that can work with upto 1000 products.
I need to select all products that have no specific part assigned. I tried a left join
"select cols from products left join parts on products.id = products_parts.productid where partid!=3 and products_parts.productid is null"
The statement is correct to my knowledge but because of too much data in relationship table, fatal timeout exception is thrown. i also tried using not in and not exists... Again statements are correct but i get fatal exception. I say statements are correct because they work with small tables...
How will i get around this issue. For left join i would bring into consideration that product1 can work with part1,2,3 . At same time product2 can work with part 1,2 so with left join even if i say select products that doesn't work with part1 , i will get product 1 because association is with part3 this time... ( i don't know whether this was useful or not)
Actually , i want an exact inverse of inner join (not using left join coz too much data throws fatal exception, not in and not exists also not working...)
Is there any special command?
Please provide help in this regard (i am using Asp.net with mysql)
Thanks

If you are sure your sql is correct (and it does look OK to me) and your problem is actually the query timing out, how about either increase the query timeout (not sure how on MYSQL, but its probably part of the connection properties) or, better still, have a look at the indices. The table sizes your quote are very small, I would expect any database system to handle this volume of data with ease, but not if you are missing indices for your joins and there are tablescans going on.

Thanks for replying.
I used nested select statements and it worked. Left join wasn't returning proper rows because it was a many to many relationship table so product existed a number of times.

Hello,
I have a CGI script (written in C) which performs some fairly lengthy operations and I would like to display a page saying something like "Please wait while we process your request..." while the script executes.
If possible I would also like to display temporary results as the script runs (but this isn't that important).
Does anyone know how to do this using CGI?
Thanks,
Sylvain

Hello All.
I'm trying to take the index of one dropdownList, and force the other DropDown list to be equal to the first (in terms of selectedIndex and item selected)
I can successfully retrieve the index of the first dropdown by using:
<pre> var ddIndex1 = document.getElementById('mylist1').selectedIndex; </pre>
I have tried to assign the 2nd by doing the following:
<pre>document.getElementById('mylist2').selectedIndex = ddIndex1;</pre>
I then do:
<pre> alert(document.getElementById('mylist2').selectedIndex) </pre> and I can see that the index has been modifed however, when I view my page, it still displays 'Select One' which is at Index0. 
Any ideas?
-Here is how the Drop Downs are generated-
<pre>
// GENERATE DROP DOWN BOXES
function _generateDropDown(oname,bname,btype,bfield,bvalue,allOptions,numOptions){
this.o_name=oname;this.m_name=bname;this.m_type=btype;
this.m_field=bfield;this.m_value=bvalue;
this.m_allOptions=allOptions;this.m_numOptions=numOptions;
var x = "";
var myString = new String(allOptions);
var myOptions= new Array(numOptions);
var z=myString.length;
var y=0;
var currCharIndex=0;
myOptions[0]='';
try{
// PUT ALL OPTIONS FOR THIS DROP DOWN INTO AN ARRAY
for(i=currCharIndex; i<z; i++){
if (myString.charAt(i) != ";"){
myOptions[y]=myOptions[y] + myString.charAt(i);
this.m_value=myOptions[y];
}
else if (myString.charAt(i) == ";"){
y++;
currCharIndex=i;
myOptions[y]='';
}
}
//WHEN A DATE IS SELECTED
if (parent.dateIndex != -1){
complete_rs.movefirst;
var x = new String(complete_rs(bfield));
if (x == "null" || x == "undefined" || x == "Select One"){
x = "";
}
}
//WHEN NO DATE IS SELECTED
else if (parent.dateIndex == -1){
x = "";
}
if (this.m_name != "selectDate"){
document.writeln("<select name=",this.m_name," onChange=",this.o_name,".updateDB(value)><br />");
document.writeln("<option value=\"Select One\">Select One</option>");
for(i=0; i<this.m_numOptions; i++){
if (myOptions[i]==x){
this.m_selected="selected";
}
else{
this.m_selected="";
}
document.writeln("<option value=\"",myOptions[i], "\" ", this.m_selected,">",myOptions[i],"</option>");
}
}
document.writeln("</select>");
}//END TRY
catch(E){
//alert("generateDropDown()"+ E);
}//END CATCH
}
</pre>
and here are my attempts, all which do not modify the drop down to change.
(ps. the value of the dropdown is added to the database afterwards)
<pre>
var index1 = document.getElementById('mylist1').selectedIndex;
//this updates the index, however fails to change what is display in the dropdown list
document.getElementById('mylist1').selectedIndex = index1;
//this updates the index, however fails to change what is display in the dropdown list
document.getElementById('mylist1').options[index].value = index1;
//this updates the index, however fails to change what is display in the dropdown list
var tempDDL = document.getElementById('mylist1');
tempDLL.selectedIndex = index1;
</pre>
Any type of help or suggestions is greatly appreciated.
Cheers!!!
