X and Y are array list.
Bitmap objBitmap;
Graphics objGraphics=Graphics.FromImage(objBitmap);
if(X.count==Y.count)
{
for(int i;i<= X.Count - 1 ;i++)
{
objGraphics.DrawRectangle(new Pen(new SolidBrush(Color.Red)),Convert.ToInt32(X[i]),Convert.ToInt32(Y[i]),2,2);
}
}
U can take help for this example.

hi
this is part of the code causing the problem:
XmlNodeList l = outputcopy.SelectNodes("//" + tagname);
foreach (XmlNode nod in l)
{
XmlNode parent = nod.ParentNode;
if (parent == null)
{
//break here
}
}
Whenever I try this the last node in the node list appears not to have a parent, even when its not the root node. Whay is this?? I'm totally stumped.....
cheers

It would be helpful to see the Xml file that you're querying in order to figure out what's wrong... 
Picture a huge catholic cathedral. In it there's many people, including a gregorian monk choir. You know, those who sing beautifully. Then they start singing, in latin, as they always do: "Ad hominem..."

Sorry, the xml is:
<xml>
<multiply>
<variable name="x" />
<variabel name="x" />
</multiply>
<symbol>=</symbol>
<multiply>
<number>2</number>
<number>5</number>
</multiply>
</xml>
and tagname is "multiply"
cheers

Your browser does that - only it renders it. You can, in your browser, select "File -> Save As" and save it as an HTML page, then open it up in a vanilla (plain) text editor.
If you want to do this programmatically, see the example in the documentation for the HttpWebRequest.GetResponse[^] method. Just save it to a file instead of using the Console.

You can also use RegEx to strip the html tags from the response.
<br />
public string cleanHtmlTags(string inputText)<br />
{<br />
Regex objRejex = new Regex("<([^>]*?)>");<br />
return objRejex.Replace(inputText, "");<br />
}<br />

I have a web page with dynamically geneated textboxes and buttons. On click of a button, I want to pull the values from the database and populate the textboxes. I am gettinng confused between the sequence in which the client and server side code gets called. If I call server side first and then client, practically it happens in opp order . For eg-
TableCell tblCell5 = new TableCell();
System.Web.UI.WebControls.Button btn = new System.Web.UI.WebControls.Button();
btn.Text = "Copy";
btn.ID = "btnFetch"+ count.ToString();
counter = count;
btn.CommandArgument = count.ToString();
btn.Command += new CommandEventHandler(RemoveFiles);
btn.Attributes.Add("onclick","setit(" + count + "," + crash +","+ cr +","+ cav+"); ");
tblCell5.Controls.Add(btn);
tblRow.Cells.Add(tblCell5);
Even if I call in this order and set the values of variables in RemoveFiles, the javascript functions gets called first and by that time, the variables are not set.
Also if I try to call javascript from server side function, he javascript function is not yet loaded. For eg-
protected void RemoveFiles(Object sender, CommandEventArgs e)
{
stag = 1;
Response.Write(" alert("+ e.CommandArgument.ToString() +")");
cr = 6;
cav = 9;
hrs=10;
crash = 6;
Response.Write(" setit(' + count + ',' + crash +','+ cr +','+ cav+'); ");
}
Any suggestions?

How to capture 'editing whichever cell in datagrid' event? And how to recover number of row and column cell that has just been edited?
thank you for help
|
|
|
|

I'm returning a datatable from the DB, I need to add a row to that datatable for display only. That piece is working fine, the issue is I need that record to be the first record displayed in the cbo box.
System.Data.DataRow dr = WorkTable.NewRow();
WorkTable.Rows.Add(new object[] {"ALL", "AL","","","","","","",-2,1,"UNKNOWN"});
cbo.DataSource = WorkTable;
--I need to have the added line first in the combo box.
Thanks

Instead of setting the data source of the combobox to the table, set it to a sorted view. Then all you need to do is make sure that the view is sorted so that your new row is first ... perhaps by adding a new column to the table that is null for everything other than your new row. I tried this quickly, and seems to work OK, but it looks like the sort put's null values ahead of non-nulls, so you'll need to do a descending sort.

We have an app that will not run on a single computer from the network (works fine locally). I have adjusted .NET security setting the Local Intrenet to Full Trust, but the app still crashes when trying to launch.
Any other ideas?
|
|
|
|
|
How do you start the application, exactly?
If you're trying to run it from a UNC path, then the internet zone security settings will apply, even if the computer is in your local intranet.
Regards,
mav

We browse to the network path (e.g. Z:\C# Stuff\Program Folder\Program.exe) and run it directly.
This is the only computer that will not run it from the network (we have 50+ that run it just fine).
-- modified at 14:04 Tuesday 4th October, 2005
The .NET internet security settings are full trust also.
|
|
|
|
|
The problem turned out to be some network glitch with the user's profile (on the network itself).
Our I.T. dept is checking into the fix.
Thanks for your help
