Well if you were using flash then maybe you would want user interaction? If so then the simple answer would be use a picture box now and a webcontrol when you need it.

Another suggestion, not tested, but you could try create a transparent panel that covers the webcontrol hopefully capturing any user interaction attempted.

Just like a piece of glass that stops passers by helping themselves to the pie that you left cooling on the side by the window.

I've tried that panel idea and it doesn't get transparent because I have more than one layers so Windows can't process it.

How can I make the webBrowser to seem like functioning just like a picturebox?

Then why not using Picturebox itself. Either download the Image from web site of set it to Picture Box. Or You can directly set the Picture box ImageLocation of that particular image.
Like

pictureBox1.ImageLocation = "http://www.codeproject.com/SiteRes/CP/Img/Std/logo225x90.gif";

I know it isn't the answer, but this snippet was great. I've used my own code to get an image and put it in a PictureBox for years, never noticing this property. Thanks

So you need help for turning a mediocre Control (WebBrowser) into a really bad one (PictureBox)?
I think I'll pass unless you manage to provide a reasonable explanation.

I am not actually trying to turn a webbrowser into a picturebox. I am just trying to make it feel like less webbrowser-ish Smile | :)

I'm guessing that there's more in the webbrowser then 'just' a logo. Text with markup, perhaps?

Maybe you could use the Control.DrawToBitmap function, to paint the contents of the webbrowser into a bitmap? You could then show the generated bitmap in a PictureBox[^].

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.

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

MCI Video Playback - How to get MPEG-4 to work

shultas24-Jul-09 3:22

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.

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.

Copy text to clipboard

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?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
