As per the subject, does anyone have even the faintest idea, using C#, of how I make a thumbnail screenshot of a webpage programatically? There are one or two ActiveX components out there that do this, and they render it exactly as IE would, which leads me to believe that it's some kind of functionality in IE. Perhaps it's somehow loading the website into an invisible browser window and taking a screenshot that way? I need to work this out for at least two or three tasks I'd like to implement solutions for. Please note that this has to be able to be completely automatic and doable from nothing more than a given URL.

I'm trying to set the text of an item of a TreeView to bold. When i set the node font, the node continues to use the same width space for drawing the text as where the font was "plain", so the label is trunked at the end. There's a way to update correctly the space of the node?
i've used this code before adding the node to the Nodes collection:
<br />
TreeNode node = new TreeNode("Test", 0, 0);<br />
node.NodeFont = new Font(treeView.Font, FontStyle.Bold);<br />
<br />
treeView.Nodes.Add(node);<br />
|
|
|
|
|
Yes there is a workaround:
node.Font = new Font(someotherfont..);<br />
node.Text = node.Text;
I know it looks silly, but it's the only workaround I found to force the treeview to recalculate the size of text with the new font/style etc.
|

This makes sense, since setting the Text property actually causes the class to send the TVM_SETITEM message to the underlying Tree-View common control with the TVIF_TEXT flag to set the text. If you set the text first, the underlying tree view probably isn't sent the text mask and hence the text is not sent. This would best be called a bug, but why it is necessary does make sense if you understand how the TreeView class works (i.e., it encapsulates its respective common control, as do most controls in Windows Forms).

i cant see any differencies using that workaround. However i'm setting the new font before adding the node to the treeview, so the text area'd must be already recalculated, or not?

This is a simple problem. You treat each tab page as a separate class and add them to your TabControl. Expose what properties you need to from each tab page so that the TabControl can access them. A better OO design is to pass each tab page an object (such as a DataSet or whatever is appropriate so that each tab page can assign its own properties to its controls), which is best done by deriving from another base class that derives from TabPage. You need to create a good OO design.

I've been porting code to C# while using Managed DirectX 9.0b. To access memory surfaces directly i used the Surface.Lock() method, which should return an Array, but returns a byte[,]. Annoyingly, the size of this array is the size of the surface in pixels, not in bytes. E.g. working with a 100X100 pixels surface with 16bits per pixel, the method returns a byte[100,100] (half the size). Using the array position as a pointer, and navigating it manualy using SurfaceDescription.Pitch didn't help either. If you had the patience to read this, read the code:
<br />
int stride = back.SurfaceDescription.Pitch;<br />
byte[,] barr = back.Lock (Microsoft.DirectX.DirectDraw.LockFlags.SurfaceMemoryPointer );<br />
unsafe<br />
{<br />
fixed (byte* pbdata = barr)<br />
{<br />
for (int j=0; j<100; j++)<br />
{<br />
for (int i=0; i<100; i++)<br />
{<br />
*(pbdata+j*stride+2*i+1) = 0xF8;<br />
}<br />
}<br />
}<br />
}<br />
back.Unlock(barr);<br />
this should paint my surface red, but it only paints half of it red.
What am I doing wrong?
|

|

There used to be a bug regarding this that didn't actually lock all of the surface memory. Not sure if they've fixed it or not...
ok, that said, the Pitch property is the distance *in bytes* to the next line of the raster. So one "line" in the raster is actually Pitch bytes long. Hence, one pixel is (Pitch/width) bytes long. Methinks you're addressing the wrong chunk of memory as a result.

Thanks, u'r absolutely right about the pitch. sorry that my code is ugly that way (the "j" index came before the "i" somehow). but i think i've tried what you've suggested:
<br />
for (int line_no=0; line_no<100; line_no++)<br />
for (int column_no=0; column_no<100; column_no++)<br />
*(pbdata+line_no*Pitch+2*column_no+1) = 0xF8;<br />
Do I understand what you mean, or am i missing something?
You say the bug is not locking the whole surface memory? in desperation i've tried to access bytes seemingly outside my surface (like: line_no = 120); to my surprise nothing crashed (as if i've accessed something legal), but the app seemed to be in a deadlock (so maybe it was not locked)

this is my screen capture code:
Bitmap bmp = new Bitmap(800,600);
public static Bitmap GetDesktopImage()
{
IntPtr hBitmap;
IntPtr hDC = GetDC（GetDesktopWindow());
IntPtr hMemDC = CreateCompatibleDC(hDC);
hBitmap = CreateCompatibleBitmap(hDC, size.cx, size.cy);
IntPtr hOld = (IntPtr) SelectObject(hMemDC, hBitmap);
BitBlt(hMemDC, 0, 0,size.cx,size.cy, hDC, 0,SRCCOPY);
SelectObject(hMemDC, hOld);
DeleteDC(hMemDC);
ReleaseDC(GetDesktopWindow(), hDC);
bmp = System.Drawing.Image.FromHbitmap(hBitmap);//<-here
DeleteObject(hBitmap);
GC.Collect();
return bmp;
}
at the arrow place,get a bitmap instance. i think the bitmap is true color depth.
Here is my question:
1.After BitBlt method, can i get a 256 color bitmap instance directly instead of a true color bitmap ?
2.if i have to get a true color bitmap, How to convert it into a 256/16/2 color bitmap quickly ?
|

First, don't assume the desktop is 800x600. Use either SystemInformation.VirtualScreen or Screen.WorkingArea to get the Rectangle to use to size the Bitmap.
Second, you can create a 256-color bitmap by using the Bitmap.Bitmap(int, int, PixelFormat) constructor. Then create a new Graphics object for that bitmap and use GetHdc to get the DC which you could paint into. Make sure you call ReleaseHdc and then dispose your Graphics object, but do not call GC.Collect - just call Graphics.Dispose on anything you create. Calling GC.Collect can be very expensive and - if you dispose things correctly (in order to free native resources, which GC.Collect won't do) - is unnecessary.

This is a good idea, but it's not that simple if you're looking for a 256 colors bitmap.
You said:
Heath Stewart wrote:

But in such a bmp the colors are indexed, so that a code like:
<br />
dest_bmp = new Bitmap(width, height, PixelFormat.Format8bppIndexed);<br />
g = Graphics.FromImage(dest_bmp);
throws an exception with message:
<A Graphics object cannot be created from an image that has an indexed pixel format.>
|
|
|
|
|
Another idea, then, would be to save the true color bitmap to a MemoryStream using a 256-color format like ImageFormat.Gif, then either return that Bitmap or create a new one by reading that stream back in using the overloaded constructor (I'm not sure if when you save it the Bitmap is actually changed - just really never tried it).

cool. this works, something like:
<br />
public Bitmap ConvertTo256Bmp(Bitmap source_bmp)<br />
{<br />
if (source_bmp == null)<br />
return null;<br />
System.IO.Stream bmpStream = new System.IO.MemoryStream();<br />
Bitmap dest_bmp = null; <br />
try<br />
{<br />
source_bmp.Save(bmpStream,<br />
System.Drawing.Imaging.ImageFormat.Gif);<br />
dest_bmp = new Bitmap(bmpStream);<br />
}<br />
catch(Exception e)<br />
{<br />
Console.WriteLine(e.Message);<br />
return null;<br />
}<br />
return dest_bmp;<br />
}<br />
this returns a bmp with Format8bppIndexed pixel format.
only thing is, the resulting bmp, when written to disk, is much larger than the original. But that's somebody else problem ?

Can some one help me out with this C++ line of code, im trying to convert it to C#, im lost on the ** ? i look on the SDK and nothing
HRESULT CreateSession([out,retval] IMediaStatusSession** MediaStatusSession);
Parameters
MediaStatusSession
[out] Address of a variable that receives the IMediaStatusSession interface pointer.

If I undestand it correctly , for [out] , you should use ref in C#.

Furthermore you also need to define the IMediaStatusSession interface in you code. If this is a standalone method from a static DLL. But something tells me this line of code is from an IDL declaration of a COM object, in that case you just create a Runtime Callable Wrapper (RCW) with tlbimp and it will take care of converting all you interfaces and methods for you.

Grrrr... If you read the documentation on TlbImp, you will note that it works on Type Libraries (DLLs, TLBs) and NOT the Interface Definition Language (plain text files). Did a search MSDN and Goodle for these intrerface names and there is basically NO mention of these on the internet, because neither MSDN nor GOOGLE have come up with anything.... What IS this stuff?
