Progress Bar while copying, deleting files

Hi,

I would like to know if I can include a progress bar when I'm trying to copy files from one location to another with :

1. The file count unknown to me.
2. The size of each file is unknown to me.

For the above conditions, I'm able to get the normal progress bar which shows progress between the starting and final positions repeatedly.

The question is whether I can use a progress bar that shows the overall progress, just like the windows file copy progress bar...

Can anyone help me on this?

Thanks in advance,
ramzg

if you don't have the numeric information, you can't show progress information, all you can do is indicate it is still busy.

so figure out what you mean by progress, and once you know how to do it by hand, you can create some code that does the same.

Hi Luc Pattyn,
Thanks for the reply.. Ya, it is not possible to show progress information here... But I forgot to include this in my question... Would I be able to get the animation that windows uses (with a transparent background, so that I can place it on my form) to indicate that the files are being copied? Or do I have to create my own animation?

Thanks,
ramzg

this[^] and this (Using Windows Explorer Progress Dialog In Your Application)[^] could be relevant, but the Windows dialog is a dialog form and not transparant.

If you know the source of file the what is problem with counting file or File Size.

That seems like an odd thing to do.. But well, you could make an uint[] and use LockBits on a Bitmap and fill the array using unsafe code, then make a new Bitmap use LockBits again and then write the pixels back (unsafe code) to the new bitmap and then display the bitmap. Why? Because you asked.

Alternatively you could fill the array of uints with whatever else you want.

How to update button state

I'm new to C#.
I am using WebBrowser control in a form. I have a 'Back' button on the toolbar. I would like to disable the button based on 'webBrowser.CanGoBack' property. However, when browsing, I do not know when someone has clicked a link to a new page and I do not know how to create an asyncronous callback to check the property (other than using a timer; which I don't want to do). MFC C++ has MS custom WM_KICKIDLE message which could be used for such things. Can someone suggest a preferred method to do this?
thanks.

Tooting your own horn?? What's the point of constantly posting "Hey I wrote this cool article" every four hours?? You're not going to get MVP status by doing that, if that's you're motivation.

Filter out Restricted property from COM

Hi,
I have a COM component where i have declared restricted/hidden methods and properties.Using Reflection I am accessing these methods and properties.Is there any way to filter out restricted properties alone? I can able to do for methods but not for properties.

here is my code for methods:

foreach (MethodInfo mInfo in obj.GetMethods())
{
string FuncAttrib = "";
TypeLibFuncAttribute attrib = null;
attrib = (TypeLibFuncAttribute)Attribute.GetCustomAttribute(mInfo, typeof(TypeLibFuncAttribute));
if (null != attrib)
{
FuncAttrib = attrib.Value.ToString();
}

//Filter the Restricted methods.
if ((FuncAttrib.Contains("FRestricted")) || (FuncAttrib.Contains("FHidden")))
{
//here we will get only restricted.Hidden methods
}
}
This is working fine for methods.here I have used TypeLibFuncAttribute which is applicable to method alone.Can anyone help to apply this logic to properties?I have searched the attribute similar to method but not able to get......

Thanks,
Rajan.

well your query string look ok, apart from the fact you should be using command parameters to insert data from textBoxes. Is a row being created in the database at all? with just blank data?
