Hi!
I'm looking for a library or API that can help me to extract video component such as I-Frame, P-frame.
As a matter of fact, I would like to modify the DCT of I-Frame of a MPEG4 video file.
Thanks

How can i add scroll bar to my form?
|
|
|
|
|
Set the forms AutoScroll property true and make the form so small that at least one control is located outside the form's client region.

hi all,
i have a msaccess database with 3 fields 'case', 'dateopened' (day,month), houropened(hour,minute,second) and 'whoopened'.
i have such a data text:
******************** CASE OPENNING RECORDS OF 80 ENTRIES ********************
***************** (MONTH/DAY-HOUR:MINUTE:SECOND-#AUTHORITY) *****************
------------------------------- CASE NO: 9876 -------------------------------
05/12-17:25:05-#3 05/12-17:24:56-#3 05/12-17:24:44-#0 05/12-17:24:32-#3
05/12-17:24:22-#3

how can i parse this text and get case No and other datas from ?
many thanks in advance.

Well, it depends on if you can format the text as you want..
If your text is a bit small (something like few kilobytes), and performance is not an issue here you may want to directly use the (IndexOf) function to locate cretain Keywords (eg. "RECORDS OF ", "CASE NO: ", or "DATA END"), also then you may reformat your data text to be something like this:-
[CASEOPENNING] [RECORDSOF] 80 [ENTRIES]
[DATA]
[CASE NO]9876[/CASENUMBER]
05/12-17:25:05-#3[NEWENTRY]05/12-17:24:56-#3[NEWENTRY]05/12-17:24:44-#0[NEWENTRY]05/12-17:24:32-#3
[NEWENTRY]05/12-17:24:22-#3
[CASE NO]6675[/CASENUMBER]
05/12-17:25:05-#3[NEWENTRY]05/12-17:24:56-#3[NEWENTRY]05/12-17:24:44-#0[NEWENTRY]05/12-17:24:32-#3
[NEWENTRY]05/12-17:24:22-#3
[/DATA]
where you can look to for the index of "[NEWENTRY]".
Then it's easy!!
If your text data is a bit large & you want to boost the performance you may want to try the "ReadLine" function to read your text line by line. Then in the read text parse it with (IndexOf) in a way similar to the above.
There are many other ways to parse and format any text. This was merely a suggestion , Good luck.

Hi,
haven't tested it but you could try:
Icon icon = new Icon(responseStream, 16, 16);
Bitmap bitmap2 = icon.ToBitmap();
This should give you an Icon with 16x16 size but I don't know which color depth will be used...
Probably looking at MSDN[^] would also be a good idea.

I write next code:
System.Net.WebRequest request = System.Net.WebRequest.Create("http://microsoft.com/favicon.ico"); this image is Ok!
System.Net.WebResponse response = request.GetResponse();
System.IO.Stream responseStream = response.GetResponseStream();
Icon icon = new Icon(responseStream, 16, 16);
Bitmap bitmap2 = icon.ToBitmap();
TabPage1.Image = bitmap2;
it is don't work
in this line error
Icon icon = new Icon(responseStream, 16, 16); ->This stream does not support seek operations.
but:
Icon icon3 = new Icon("D:/Program Files/EasyPHP1-8/www/e107n/favicon.ico", 16, 16);
Bitmap bitmap3 = icon3.ToBitmap();
TabPage2.Image = bitmap3;
is work (16, 16: Ok)
how to fix this problem?
I need load image from Internet.

You should try loading the whole response into a byte array (GetBytes), create a new MemoryStream with these bytes and use this stream in the Icon constructor. The MemoryStream should be capable of doing seek operations.

Hi,
I need to hit-test a graphicspath object, the path could have had any number of transformations applied to it. For example, I've added a rectangle (X=50, Y=50, W=200, H=200) to the path, it's been rotated at 45degrees. Now, while it draws correctly, the hit-testing (GraphicsPath.IsVisible) doesn't seem to work with the rotation, if the path hasn't had any transformations applied, the hit-testing works perfectly (the same as Rectangle.Contains it would appear), but when it's transformed...nadda. Doesn't work.
Thanks in advance for any light you may be able to shed!

You should be transforming the mouse coords too I think... it's been a while since I worked with that.

 How to rollback the installation process in case of wrong serial number in c#.net under deployment project ?

Reinstall and install again

There are no ways to change the serial number of visual studio. If you want to change the serial number, you must reinstall your visual studio. That's what Microsoft said.

Hi. I'm trying to use p/invoke on some standard C library. The library defines a struct:
<br />
typedef struct {<br />
FLAC__FrameHeader header;<br />
FLAC__Subframe subframes[8];<br />
FLAC__FrameFooter footer;<br />
} FLAC__Frame;<br />
where FLAC__FrameHeader, FLAC__Subframe, and FLAC__FrameFooter are other copmlex structures.
The library declares a function that consumes a FLAC__Frame as argument, such as :
void someFunc(FLAC__Frame frame);
[These are snippets from libFlac, for those in the know, but this is not really relevant; see here for more on FLAC.]
The question is: how do you marshall the struct to pass it back and forth between C# code and the C library function ?
I've tried to describe the FLAC_Frame structure as this, among other things:
<br />
[StructLayout(LayoutKind.Sequential)]<br />
internal struct Frame {<br />
public FrameHeader Header;<br />
[MarshalAs(UnmanagedType.ByValArray, SizeConst = 8)]<br />
public Subframe[] Subframes;<br />
public FrameFooter Footer;<br />
}<br />
<br />
[DllImport("libFlac.dll")]<br />
private static extern void someFunc(Frame frame);<br />
but I keep getting a TypeLoadException with the comment "Cannot marshal field 'Subframes' of type 'Frame': There is no marshaling support for this type."
It does not seem to like the array of Subframes embedded in the Frame structure.
Anybody would have hints ?
Thanks,
Pyt.
