Yes there might be more than just a logo in the webBrowser control, like text or flash animations.
For everything except the flash animation DrawToBitmap is a great solution. But not completely suitable for me.
Thank you all for your answers by the way.

Last option[^] that I'm aware of would be to override WndProc and eat all messages regarding the mouse

That could be a little bit much. 
I will go for Picturebox.ImageLocation for now.

I like your thinking, keep up the good work

Hi SimpleData,
I think we're kind of "dancing" around here trying to guess what you are doing, but it seems to me that if your usage scenario is this :
1. I want a PictureBox, and under certain conditions I want a WebBrowser
Then why not write dynamic code so that when the right conditions are met you take the default control you are showing (either PictureBox or WebBrowser) and replace it with the other control.
You could pre-configure a WebBrowser, and hide it until required at run-time and then, when you make it visible, hide the PictureBox, or you could create a new WebBrowser on the fly, on-demand.
Why use a "heavy weapon" like a WebBrowser until you need it ?
If you've really got to make an un-clickable WebBrowser, use the very common JavaScript snippets that disable the click event and disable the context menu, etc.
best, Bill

Hello Everyone!
I am building a test application that plays video files. I found a tutorial and am importing WinMM.dll, and calling mciSendString to open the file and then play it back. It works great for almost all videos except MPEG-4. When I load an MPEG-4 file, MCI returns an error that the specified device is not open or not recognized by MCI. I originally thought this to be a codec issue, however I can open and play the file back in Windows Media Player just fine. I went and downloaded ffdshow just in case, but I still receive this error from the MCI device. Is there something I am missing to tie this together, or is it just not possible? If it is not possible, could someone please point me in the right direction to head so I can make an application that allows me to play back MPEG-4 video? I only need very basic control (Play,Stop,Pause,Seek). I am building an application that is going to view two video files side by side and display them simultaneously for evaluation.
Thank you in advance!
EDIT: I think they are using H.264 encoding on their MPEG-4 file if that helps, but none of the video inspectors that I have used on the file have been able to successfully tell me what codec exactly it is using.

sorry i couldn't get answer..properly..
what is meant by "yes"..

I qouted the part of question and thn said yes.
In between, once you close the form the timer control created inside that will dispose itself. You do not need to explicitly do this.

Hi, I want to copy selected text (e.g. from Firefox) to clipboard using hot key.
This is part of my code:
switch (m.Msg)
{
case WM_HOTKEY:
if ((short)m.WParam == hotkey.HotkeyID)
{
Clipboard.Clear();
SendKeys.SendWait("^c");
SendKeys.Flush();
if (Clipboard.ContainsText())
{
string text = Clipboard.GetText(TextDataFormat.UnicodeText);
RichTextBox rtb = new RichTextBox();
rtb.Text = text;
rtb.SelectAll();
rtb.SelectionFont = new Font(new FontFamily("Verdana"), 9.0f, FontStyle.Regular);
Clipboard.SetText(rtb.Rtf, TextDataFormat.Rtf);
}
else
{
MessageBox.Show("Error!");
}
}
break;
default:
base.WndProc(ref m);
break;
}
When I use my application first time it is working fine, but later I recive message "Error".
Can anybody help me solve this problem?
Thanks...

Well the error message your getting looks like the one you have in the messagebox in your else block. Which as every good programmer should no will only happen when your if statement (or any addition else if statements) fails. i.e. Clipboard.ContainsText() is returning false

I'm a bit puzzled about your intentions here.
So you are trying to convert text to formatted text, however when you execute Clipboard.SetText(rtb.Rtf, TextDataFormat.Rtf); the formatted test *replaces* the original text, hence the next time your code runs it doesn't find any text on the clipboard.
If what you want is having both unformatted and formatted text on the clipboard, there are ways to do that with DataObject IIRC; however even then executing your code twice wouldn't make much sense since it would replace the formatted text by the same formatted text.
Maybe all you need to do is remove the MessageBox?
or think about your functional requirements first and tell us about them.

My purpose is copy to clipboard selected text (for example in Firefox, Notepad, etc.) using hot key (for example (Ctrl+Shift+C).
I select text and use my hot key. Text is in clipboard, fine. But only if I use it first time. Later my clipboard is empty.
Why?

Don't know what this means. Is it going ok? Can you post block of your code? Is the timeout on the server it is copying to?
Excellence is doing ordinary things extraordinarily well.

Copy them in smaller blocks of records instead of all at once.

1 lac means one-hundred-thousand. From the Sanskrit lakshaya : most often transliterated into English as "lakh."

Below is some code that validates entries in a datagridview against entries in Active Directory and changes the color of the datagridview cells accordingly. A progressbar indicates how far the process is from finish. If the user then interacts with the form either by dragging one of the datagridview scrollbars or pressing a button, the program becomes unresponsive and the form doesn't refresh any longer until after the process is finished, thereby causing the progressbar to loose its functionality. How can I overcome this glitch? I would also like to implement a cancel button so that the user can cancel the validation process at any moment, but if a button is pressed I experience the problem mentioned above. Any help would be appreciated. Thanx.
private void btnCheck_Click(object sender, EventArgs e)
{
using (DirectoryEntry de = new DirectoryEntry(adPath, adUsername, adPassword)) //))
{
de.Username = Environment.UserName;
de.AuthenticationType = AuthenticationTypes.Secure;
//these are the attributes that will show
string[] attribs = new string[] { "displayName", "mail", "userAccountControl" };
for (int x = 0; x < dgvManager.Rows.Count - 1; x++)
{
ValidateDetails(4, 5, 6, x, de, attribs); //Second in charge
ValidateDetails(7, 8, 9, x, de, attribs); //Branch Manager
ValidateDetails(10, 11, 12, x, de, attribs); //Regional Manager
ValidateDetails(13, 14, 15, x, de, attribs); //General Manager
ValidateDetails(16, 17, 18, x, de, attribs); //Managing Director
progressBar.Value = Convert.ToInt32(Convert.ToDecimal(x) / dgvManager.Rows.Count * 100);
lblPercent.Text = Convert.ToInt32((Convert.ToDecimal(x) / dgvManager.Rows.Count * 100)).ToString() + "%";
this.Refresh();
}//for
}//using
}
private void ValidateDetails(int cell1, int cell2, int cell3, int row, DirectoryEntry de, string[] attribs)
{
DirectorySearcher ds = null;
string y = "", u = "", z = "", sFilter = "";

sFilter = String.Format(
"(&(objectCategory=person)(sAMAccountName={0}))",

u = sr.Properties["userAccountControl"][0].ToString();
if (u == "514" | u == "66050") // account disabled
dgvManager.Rows[row].Cells[cell3].Style.BackColor = Color.Orange;

Sounds like you need a background worker[^]
Basically, its another thread but fairly easy to work with. The problem you are getting is that your current code is running on the UI thread thus causing issues with user interaction such as button clicks etc.

You need to use Background worker in this case, which will help you show the progress of process with out any problem.
Here is an sample application
