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 ?
manu sharma

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.

Yes, indeed. Sorry if this wasn't clear.
Subframe is a struct containing other structs (there are actually several levels of nested structs).
Pyt.
|
|
|
|

I was thinking, the exception thrown probably has inner exceptions, that might give you more detail. Failing that, try Marshal.SizeOf() on the SubFrame, if u get a number back and no exception, then it should work.
Finally failing that, you can define 8 structs in a 'row' perhaps.
|
|
|
|
|
Well, there was no inner exceptions. I finally put the 8 structures in a row, and it worked. Not very handy, but it'll do the trick for now. Thanks.
Pyt.

Hi,
I'm converting char[] to double using
Dlength = System.Convert.ToDouble(strdata);
But its throwing exception called "Unable to cast object of type 'System.char[]' to type 'System.IConvertible'.
Any idea?
|
|
|
|
|
Assuming that the char[] contains something like { '9', '.', '2', '5' } then you should convert the array into a string, then pass that into the ToDouble method.

<br />
char []ch = {'1','2','3','.','2','3'};<br />
String str = new String(ch);<br />
Console.WriteLine(Convert.ToDouble(str));<br />
Hope this would solve the problem.

I have a sequence of 8-9 non ADO.Net operations needs to be done as a transaction. All of these should happen together or none of them. Is there any transaction support in C# for non ADO.Net operations?? If not what would be the best way to code this situation.
|
|
|
|
|
If you are using .NET 2.0 there is the System.Transaction namespace. Otherwise, you could use COM+.

I have a gridview on a webform. The table with the data I want it to display has a column with contents like: "Item1 Item2 Item3". What I want to do is make each one of these items appear on a new line in the cell that they are in. How would I do this?
eg.
Some Column
------------------------------
| Item1 |
| Item2 |
| Item3 |
| ... |
|___________________|___________
| |
| |
| |
| |
Thanks for any help 
|
|
|
|
|
Well, have you tried to format the text of the cell as : "Item1\r\nItem2\r\nItem3\r\n"?
