Is Possible to hide the page count pop-up that is showed when previewing
a document in the printpreviewcontrol ?
|

No it's not. You'll have to write your own print preview control to to do that. You'd want to look into the PrintPreviewControl class before starting on your own PrintPreview Dialog.

Hi,
I'm trying to access a SQL server in a newly created worker thread. This doesn't seem to work (can't even open a connection!). Is this by design? Can I only access the server in the initial thread?
Thanks for any help!

You don't give us a lot to go on. What is the Exception thrown, how are you connecting. Us knowing these things might be useful..

Sorry!
I'm trying to execute a fairly long list of SQL Commands and I don't want my GUI to hang while dealing with the database. So I've created a seperate thread, which should take care about business.
In this WorkerThread I'm connecting to the Database using an SqlConnection object and a valid connection string. When calling the Open() method, nothing happens. Using the SQL Profiler tool I can't see anything going on at the SQL Server and there is no Exception thrown.

This usually works, and I do this a lot. Please post some small piece of code which reproduces the problem so we may be able to help you...
Yes, even I am blogging now!

It seems to work for me:
using System;
using System.Collections;
using System.ComponentModel;
using System.Drawing;
using System.Windows.Forms;
using System.Data.OleDb;
using System.Threading;
public class WindowsForm : System.Windows.Forms.Form
{
public static void Main()
{
Application.Run(new WindowsForm());
}
public WindowsForm()
{
Thread t = new Thread(new ThreadStart(GetData));
t.Start();
}
private void GetData()
{
string query = "SELECT * FROM users";
string constr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\\test.mdb;";
OleDbConnection conn = new OleDbConnection(constr);
OleDbCommand cmd = new OleDbCommand(query, conn);
conn.Open();
try
{
OleDbDataReader reader = cmd.ExecuteReader();
while (reader.Read())
{
MessageBox.Show(reader.GetString(0));
}
reader.Close();
conn.Close();
}
catch(Exception e)
{
MessageBox.Show(e.Message);
}
}
}

Hi...
I have a pictureBox i would like to use as a button!
I want it to be pressed when i press the enter button, and when i press the Tab button it have to get Focus or something (maybe change image) so the user can see he is at the "button"!
I have the Cursor.Hide() Enabled so the mouse dont work!
Thats why i want the pictureBox to could use TabStop!
First i tried to set the BackgroundImage on the Button, but it didn't look good at all!
So if anyone can help me to make a pictureBox to use tabstop and/or work as a button i would be very happy!

Have you tried using a BUTTON with the IMAGE property set to your graphic???

Yes... it still don't look good!
A black line is all around the button!
And it don't look good with that line

I would think then that your only other option is a bit uglier.
Mark the button as OwnerDraw = true and do your own graphic drawing of the button.
You could create your own button inherited from button ... but then again you still are doing your own drawing of the graphics. Hmm...guess it is really only one option.
Just using a picture box will not inherently give you the behavior of a button. It is doing what it is intended to do which is display a graphic and probably inherits from the same base object as label.

You could use a PictureBox as a button, it's just a LOT more complicated than using an actual button and customizing it the way you want.

I'm creating a website mirroring tool that allows you to filter html and image files by thier file size, but I'm trying to figure out the best way to do this. Is there any way to determine the size of a remote html or image file? Or would one have to download the file and then check the file size? Help is greatly appreciates!!

Correct, or you could have a remote object on the server check it for you and simply return the value.

Not an option - trying to code it from the perspective of people not having the rights/capabilities/knowledge to have a program on the remote server like that, just plain site mirroring via HTTP

|

If this were the case how would people even know what files existed and where?

You could write a remoting object on the webserver and have the client open a channel to that object. By implementing an interface on the remote object....then the user could access info via the methods GetList() and GetSize(string item) where item is a file exposed via GetList. The user would not need any 'special' security if you set it open as such. However this should only be exposed in an internal application and not for Internet Consumption.

One way to do it is to make a request for the file, the content-size is one of the headers sent back so you get the size without the contents, but you still have to make a request per file rather then get a list.
I'm not sure, but there might be a head request to get the content size as well. Or if the server supports WebDAV, it might have methods to get that information as well.

You can use the following HTTP Headers:
Content-Length and Content-Type.

How would I capture the X and Y point location of the user's insertion point in a System.Windows.Forms.RichTextBox instance?

I've been hesitant to answer this since I don't have all of the specific calls to make...but lets assume this:
You have an RTF box and the cursor is positioned somewhere inside a valid location in that control.
You have a button which they press and it that button is [Insert Clipboard] for example.
First you get the cursor location by getting this.Cursor.Postion and maybe even you can get this.Cursor.Position.X and .Y but it's not important.
The part I cannot remember is you make a call (into the control?? or into Application???) which translates the relative location of the cursor on the desktop to the relative position of the cursor within the control.
Maybe Nick can add to the reply as to the specific call....but if not, you have a starting point.

Thanks for your help. I finally figured out how to do this and it might help others who might need or want to know how to do this. Below is the bit of code I used to get the Point location of the insertion point.
rchEdit.GetPositionFromCharIndex(rchEdit.SelectionStart)
This did it. GetPositionFromCharIndex(...) when passed the selection start index, returns a Point instance at the insertion point's index (or at the beginning of a selection).
Happy Programming and may God Bless!

I have need to authenticate users using windows authentiateion. I am using following code to do that. But problem with this is after three unsuccessful attempts, it locks user out from other applications using Directory Service, the same way when we try to login to windows machine and three consecutive wrong passwords locks the users out.
Does anybody know how can I use Directory Service to make non-blocking call upon wrong password
DirectoryEntry entry = new DirectoryEntry("LDAP://RootDSE");<br />
String str = entry.Properties["defaultNamingContext"][0].ToString();<br />
MessageBox.Show(str);<br />
DirectoryEntry domain = new DirectoryEntry("LDAP://" + str, txtLogin.Text, txtPassword.Text);<br />
<br />
<br />
try<br />
{<br />
Object native = domain.NativeObject;<br />
MessageBox.Show(txtLogin.Text + " Authenticated. Hurray!!!");<br />
}<br />
catch(Exception )<br />
{<br />
MessageBox.Show(txtLogin.Text + " INVALID user :-((");<br />
}
Thanks you very much,
Ruchi
