Well, this is not a common question. In fact, we use version information to store the file's abstract, such as version, company, name, etc.

So far as I know, it is possible to obtain the abstract info, rather than modify it via C#. Maybe you need to look for windows native api to tackle this issue.

If you don't know any applications for it, why do you want the code ?

Oh, it's home work. Do it yourself then.

Custom Open Dialogs with WebBrowser Control

public Key GetKeyBasedRandomPermutation()
{
int baseFileNum = 42;
Key keyz = new Key(New RandomPerm("BaseValue"));
While baseFileNum > 0
{
   keyz.Permutation.Randomize(baseFileNum);
}

return keyz;
}

That should do what you want (don't forget to include the Ms KeyPermute namespaces!)

One of the applications would be in a teaching environment, where you need to create Key-based random permutations in order to facilitate the development of non-pseudo responsive transitional processing. Optional modular concepts are, of course, optional!

Good luck!

Hi,

I have a WebBrowser control in my C# application, and I am trying to show a custom open dialog when the user the user tries to upload a file or attach a file to a website or gmail.

I am clueless in this case, I have my custom open file dialog which should come up instead of the typical windows common dialog file open dialog.

any ideas?

As the WebBrowser control is just a wrapper for IE, then your application will have little, if any, control over what pops up.

So unless there is away to make the web browser use a different file selector (which will probably require a hack to windows to make it do so) I think you may be onto a loser.

(Caveat - I probably don't know what I'm talking about)

Ok, i figured out most of it...

What I am doing now is that I am parsing out all the input tags with type=file... these are the file upload input tags using HtmlElement and setting their mouseup and keypress event handlers to my custom handler.

Now that i am done with this I am trying to do this:

HtmlElement elm = .....;
if (elm.GetAttribute("type") == "file")
{
elm.SetAttribute("value", myString);
}

this is not working! is there any way set the value attribute on the input tag?

Using IAccessible to navigate across Datagrid rows

Hi to all,

I'm having a problem... i have to get child rows from a Datagrid control on another application, i'm using IAccessible interface to get Datagrid control (it works Laugh | :laugh:

), but i'm don't have any idea about get child rows Confused | :confused:

. In another words, i have to get datagrid content and later use it for another operations.

There is the method used to get DataGrid IAccessible interface:

IAccessible FindAccObj(string controlName, out int childID);

Thanks in advance to any help. Thumbs Up | :thumbsup:

Graphs disappear from panel

StuffyEst5-Mar-09 10:58

Hello there,

First of all I know this is a question asked many times etc. But still I'm quite stuck since I haven't found an answer that would work for my case.

So, my project is made in Borland (C# Builder) and consists of following:

- I have a panel where graphs are generated (note: 2+ graphs)
- I have sliders to change the values inside graph function (to make them longer, move them up or down, etc.)

The problem I'm having is that, when I move the window out of bounds, or place another window over my graphs, they just disappear.

I've read about the OnPaint, but I'm not sure how I'm suppose to add this to my code, since my graphs are updated every time trackBarNR_Scroll event occurs.

Oh and finally, of course it's suppose to be a Windows Application Laugh | :laugh:

Hopefully someone could guide me, how to make those graphs not disappear Smile | :)

Where/how are you creating the graphs?
Are you not drawing using the Paint event of the Panel?

StuffyEst5-Mar-09 11:54

As a matter of fact, I'm not (and besides I'm not that familiar with C# yet Big Grin | :-D

)

One of the Graphics function is here (and that is called every time I have trackBarNR_Scroll):

		private ArrayList GraphPointsList2 = new ArrayList();<br />
<br />
		private void DrawGraphic2(int k3, int k4)<br />
		{<br />
			int i=1;<br />
			int j=1;<br />
			int x=0;<br />
			int y=0;<br />
			double value=0;<br />
			double sin=0;<br />
<br />
			Point GraphPoint2;<br />
<br />
			System.Drawing.Graphics graph2;<br />
			graph2 = GraphPanel.CreateGraphics();<br />
			graph2.SmoothingMode = SmoothingMode.AntiAlias;<br />
			Pen penCurrent2 = new Pen(System.Drawing.Color.Red, 2);<br />
<br />
			for(x = 0; x<GraphPanel.Width; x++)<br />
			{<br />
				GraphPoint2 = new Point();<br />
<br />
				GraphPoint2.X = x;<br />
<br />
				sin = Math.Sin((0.01*k4)*x);<br />
				value = 50*-sin+k3;<br />
				y = GraphPanel.Height - (int)value;<br />
				GraphPoint2.Y = y;<br />
				GraphPointsList2.Add(GraphPoint2);<br />
				i++;<br />
				j++;<br />
			}<br />
<br />
				Point[] pointArray2 =<br />
			   ( Point[] ) GraphPointsList2.ToArray( GraphPointsList[ 0 ].GetType() );<br />
<br />
				graph2.DrawCurve(penCurrent2, pointArray2);<br />
		}

Well, you may use this function in Paint event.
Add an handler for Paint event of GraphPanel and use e.Graphics (instead of GraphPanel.CreateGraphics())
In this way, your graphs will be drawn every time when the Form is repainted. Now, call GraphPanel.Refresh() in trackBarNR_Scroll() in order to refresh the graph when scrolling.

Hi,

here are a few simple rules that should guide you:

there are several steps to draw something so it becomes visible on the screen:

1.
decide upon what object you want to draw; it normally is a Control (e.g. a Panel) or a
Form itself. I prefer to add a Panel to a Form, then draw on the Panel.

2.
create some variables (Rectangle, struct, class, whatever) that hold the parameters of
your drawing. For a rectangle that could be top and left coordinate, and width+height,
or just a Rectangle. etc.

3.
create a Paint handler (either add your own paint handler to the Paint event, or
override the OnPaint method) for that Panel, and do all your drawing in there,
using the Graphics class and your variables.

4.
when you want to change things, modify the variables and call Panel.Invalidate() or
one of its overloads (for selective invalidation).
5.
If you want to animate things, perform the move (step 4) inside the Tick handler
of a Windows.Forms.Timer

BTW: if you need to create some objects (Fonts, Pens, Brushes, ...) either keep them
alive in class members (hence create them only once); or create them inside the Paint
handler and don't forget to call Dispose() on them.

Smile | :)
