Hi,

this is what I would do for simplicity and performance:
- get rid of all those PictureBoxes, replace them each by a Panel;
- load the original images in Bitmap objects once;
- don't create new Bitmaps at different resolutions;
- in each Panel's OnPaint handler simply draw the corresponding image using one of the many
Graphics.DrawImage() overloads that allow to specify both the source Rectangle and the
destination Rectangle, resulting in automatic pan&zoom capabilities.
- when the pan/zoom parameters change, call Invalidate() on all Panels that need a repaint.

Smile | :)

Draw a box and extrude it. Then, draw a smaller box, and use it as a null object to cut it out of the bigger box. Finally, rotate the box. Here's a quick sample of an X file:

WPF: Rounded rects on only certain corners?

Hey all. I posted this here because I don't see a specific WPF forum.

I'm curious if anyone else has wanted to or figured out a way to draw rectangles with only certain of the four corners rounded (for e.g. the bottom corners only). I bet I could sit down and work out a way to do this, but I'm new to WPF so wanted to see if it's been done before.

Thanks,
Logan

You can do it, but you have to get a bit tricky. The window border itself can’t be changed, but you can make a borderless window with a shape inside of it that does what you want. You then have to enable dragging the ‘window’ based on dragging its contents, but it’s not a big deal.

Start by setting the following styles on the window:
WindowStyle="None"
Background="{x:Null}"
AllowsTransparency="True"
ResizeMode="NoResize"

Inside this window you’ll need to place a Border object. Inside the Border you can place whatever you want. Now on the Border set its CornerRadius to something like CornerRadius="0,22,0,22" and set your fill and stroke as desired.

Finally, you’ll need to be able to reposition the window regardless of where the user clicks. Fortunately WPF lets you capture events both on the way down (Preview) and on the way back up through the element stack (Element). So to complete your project, in your window class add the following code:

protected override void OnMouseLeftButtonDown(MouseButtonEventArgs e)
{
base.OnMouseLeftButtonDown(e);
DragMove();
}

And that’s it. You can use this trick for creating windows of literally any shape. Even animation should be supported, though I haven’t tried it. Disclaimer: I’ve only tried this on Vista. I think it SHOULD work on XP, but the Desktop Window Manager in Vista may make a difference.

Ha ha ha. I just realized you only needed the rounded rectangle and I took you all the way to the rounded window. Oh well, all you needed was the CornerRadius bit. And I think you even wrote an article already? Well, good job!

Haha, yes I wrote an article for a Shape-derived class called PartiallyRoundedRectangle before I found out about Border's ability to do essentially the same thing. I found out about that through the article though, so it wasn't a complete waste of time. Wink | ;)

Thanks for the in-depth instructions for making rounded borderless windows even if it's not exactly what I was asking for. Wink | ;)

Addind a Toolbar window into a MDI frame window [modified]

Tien-Thong22-Nov-07 12:58

22-Nov-07 12:58

Hi,

I'm actually writing a CLIENT/SERVER TCP/IPv6 application, under Microsoft Visual Studio C++. In which the SERVER is a file server application and the CLIENT is a "Multiple Document Interface (MDI)" and "RichEdit Text" application that can open multiple files from the server.

I would like to add a Toolbar window into my MDI frame window, to do this, I've created the Toolbar window with the "CreateToolBarEx" function.

But the created Toolbar window is located in the client area of the MDI frame window and each time a new MDI child window is created to hold a new document, it erases the Toolbar window in the client area.

My question is how can I do :
1) To change the client area size so that fits
height(MDI Frame window) - height(Toolbar window)
OR
2) To include the Toolbar window into the
non-client area like the Menubar and the Titlebar

So that the MDI child window can't anymore erase the Toolbar window in the client area.

Thanks,

Alain NGUYEN

Save animation to movie

Sorry if my english is not good.

I'm building a program on Windows that take in a table and draws chart, text and some animation effect(text running in bottom of screen). The program must export that to a .avi file.
How can i do that?Do you know any library that can directly manipulate a .avi file like draw on a frame.
Or a library can convert a list of pictures to .avi file.

In Windows, you can hold down the alt key and press the "print screen" key to copy an image of the active window into the cut/past buffer. Then you can bring up paint, use paste, and save or print the image. You can also use ctrl and "print screen" to copy the entire screen.

There's three System.Drawing.Bitmap constructors that take a System.Drawing.Image as a parameter...

Hi,

thanks for the reply. Im new with C# (started with TP and mainly work in php / MySQL) so constructors is all new to me... Been looking around and cant seem to find the right thing/way to do this.

if i have

System.Drawing.Image modimage;<br />
System.Drawing.Bitmap modbitmap;

changes are first done to modimage and then i want to do something like

modbitmap = modimage;

and then carry on with changes to modbitmap.

obviously the modbitmap = modimage; does not work as it is like trying to say
strSomething = intSomethign;

it would be nice if there was a thing like
modbitmap = modimage.tobitmap(); lol

anyway, my trials have proved fruitless so i am hoping that you would be kind enough to spare a min and help me out.

thanks in advance. Cool | :cool:
