.Net doesn't have PDF support. You have several options

1) Read the PDF spec, and the Word doc spec and write your own converter.
2) Find a commercial PDF library. There are several around.
3) Use ITextSharp[^]. It's an open source PDF creator. It allows you to create PDF files on the fly from C# (Note, it is not a converter, you'll have to process the word file and manually work out what to put in the PDF)
4) Automate software that does the conversion for you. (Like openoffice) There is an article on CP about this http://www.codeproject.com/KB/files/generatepdf.aspx[^]. You would either need to ensure the user has open office installed on the system, or provide the conversion as some form of web service which you can call. (This is good if it's an internal only company app, and you can host a service on the network)

If that could be done, that would be an excellent CodeProject article

It would indeed be a insane task. (Although, there are clearly people who have done it).

I thought I'd take a quick look at the PDF spec.
http://www.adobe.com/devnet/pdf/pdf_reference.html[^]

Turns out it's provided in some sort of "PDF package" where multiple PDFs are bundled together into one file. It's a new feature, and Foxit doesn't seem to support it, and I refuse to use adobe reader. I'm convinced they just do things like this to annoy the hell out of developers. Why on earth are "PDF packages" needed? If you want multiple files in one, zip them.

Progress Bar Problem

No, you can't.

The progress bar is a base windows control. When you request that the API create one, you will get a progress bar in the windows style. There are different themes available that change the styles. If you run your app in vista, you'll see the progress bar will adopt the vista style.

Your only option would be to create a custom/user control and manually create a progress bar. The disadvantage of this though is that it won't automatically fit the users theme, or change style for vista.

See Ravi's reply below.

You have to write (or find) a custom control that does that. There just happens to be one here on CP. Search for "SmoothProgressBar".

Other than looking for a progressbar custom control on the CodeProject, you can always modify the .NET 3.0 progressbar color scheme(WPF).

Assuming he wants to use WPF, of course. I wish the questions posted here would be more complete.

But I'd already checked that property.

Both Blocks and Continous shows dotted line.

Have u checked that?

Running object table changed event

Hey everybody!

I'm trying to find an event that will be fired every time there is a change in the ROT.
Does anyone know about such a function (WIN32 API maybe?!) ???

If there is no such event I was thinking about creating a thread that will re-enum the ROT every 500ms and notifies me if there is such change, but I still hope there is a better way...

Thanks!!!!

Modeless Form with invisible controls [SOLVED] [modified]

#realJSOP31-Jul-08 0:41

#realJSOP

31-Jul-08 0:41

Yesterday, I posted a message here about creating a modeless form with a single label control that was not being rendered by the form. Towards the end of the work day yesterday, we had all thought it might just be a problem on my computer (VS2005/SP1 on Vista). However, when I brought the code home and tried it, it happened there too (VS2005/SP1 on XP). It also happened on VS2008 using .Net 2.0 and then using .Net 3.5.

What's really disturbing is that two people here on CP tried the same code, and it did not occur for them.

--------------

This morning, I figured out how to force it to render the control. I added this function to the modeless form:

public void UpdateForm()
{
    this.label1.BringToFront();
    this.Update();
}

and then modified the code that opens/closes the form (remember, this code is in the DoWork() handler of a BackgroundWorker object) looks like this:

private void splashWorker_DoWork(object sender,DoWorkEventArgs e)
{
	BackgroundWorker thisWorker = sender as BackgroundWorker;
	SplashPanel splashPanel = new SplashPanel();
	splashPanel.Show();
	splashPanel.UpdateForm();
	while (!thisWorker.CancellationPending)
	{
	    Thread.Sleep(500);
	}
	splashPanel.Close();
	splashPanel.Dispose();
}

I couldn't find ANYBODY ELSE on the net that had experienced the non-rendered controls problem that I've experienced. In the process of trying to figure t=out the problem, I tried using calls to MessageBox.Show() within various form event handlers, and discovered that the act of displaying a message box caused the label control to be properly displayed. Invalidating the control didn't have any effect. Hiding/showing the control didn't work. It was only out of desperation that I finally discovered that calling BringToFront() would show the control.

I want to know WHY this is necessary, or what is wrong with my Visual Studio (or .Net) install that would cause this problem.

[EDIT] I've come to the conclusion that this is a bug in the .Net framework, starting all the way back at .Net 1.0, and is probably related to the Event loop not being fired correctly. I added a bunch of other types of controls and all of them exhibited the same behavior as my original label control. Everything is fine as long as you are using a modal form (using ShowDialog() to display the form). However, displaying the form as modeless, you get screwed up up results.

normalize URL

George_George31-Jul-08 0:13

Hello everyone,

Some URL representations, like "www.google.com" is not legal and will cause format exception when we use it to form URI class. In this specific case, it is because http:// is missing.

My questions are,

- Is what URI class doing conforming to industry standard about what is legal form of URL? Or URI class is doing something special to decide whether or not format exception will be thrown?

- Suppose we have URL strings like "www.google.com", how to make such strings "good format" to URI class? Any utilities' class to transform?

thanks in advance,
George

That's because it is not an URL, its a hostname. Prefixing a protocol will turn it into an URL. IE and browsers, normally help the user out with this (by prefixing http:// automatically).

Thanks leppie,

Using IE is a manual solution. Is there any ways (e.g. .Net built-in class or some other samples) to automatically convert URL into good format? Smile | :)

George

I don't think there is one as it would never be definitive.

IE assumes http:// if it's ommitted, but it could be https://, ftp://, etc... etc...

You need to decide yourself what you expect and check/format it as needed.
