I was wondering if there was any way to see what functions are availble in dll's. For example how can I find out the available functions for the user32.dll?

If you really want to get oldschool, use the dumpbin[^] utility.

1) Open up your form in design view
2) In the toolbox, Right click and select "Choose Items"
3) When the dialog pops up, click the "Com components" tab
4) scroll down to "Microsoft Visio x.x Drawing Control" and tick it.
5) Hit OK
6) The control will appear in the toolbox under General.
7) Drag the control onto your form.
You can use this control to display a Visio drawing and allow the user to edit it. See the MSDN article above for a tutorial of using the control.
Note that this will bind to a specific version of Visio. The user must have that version installed to use your app. There is a way of bundling up a lite installer with your app, that the article talks about. I would assume the user still has to have a Visio license, but I'm not sure.

You need to do this by inspecting the website using the DOM. It's not a simple thing, the web browser is it's own world, it doesn't expose stuff like a windows app

You will need to define the connection parameters to the report within your code.

hi
i need a control that display my image maps and panning and zooming it in my control.
i was create a userControl named ImageMap, and add a panel to it and set Doc to Fill and wrote this code to get result :
public partial class ImageMap : UserControl<br />
{ <br />
Bitmap bitmap; <br />
BufferedGraphicsContext currentContext;<br />
BufferedGraphics myBuffer; <br />
PointF viewPortCenter;<br />
float Zoom = 1.0f;<br />
<br />
bool draging = false;<br />
Point lastMouse;<br />
public static Rectangle rec;<br />
<br />
<br />
public ImageMap()<br />
{<br />
InitializeComponent();<br />
currentContext = BufferedGraphicsManager.Current;<br />
setup(false);<br />
rec = this.panel1.DisplayRectangle;<br />
} <br />
<br />
private void setup(bool resetViewport)<br />
{ <br />
if (myBuffer != null)<br />
myBuffer.Dispose();<br />
myBuffer = currentContext.Allocate(this.panel1.CreateGraphics(), this.panel1.DisplayRectangle);<br />
if (bitmap != null)<br />
{<br />
if (resetViewport)<br />
SetViewPort(new RectangleF(0, 0, bitmap.Width, bitmap.Height)); <br />
} <br />
this.panel1.Focus();<br />
this.panel1.Invalidate();<br />
} <br />
<br />
private void SetViewPort(RectangleF worldCords)<br />
{ <br />
if (worldCords.Height > worldCords.Width)<br />
{<br />
this.Zoom = worldCords.Width / bitmap.Width;<br />
}<br />
else<br />
this.Zoom = worldCords.Height / bitmap.Height;<br />
<br />
viewPortCenter = new PointF(worldCords.X +(worldCords.Width / 2.0f), worldCords.Y + (worldCords.Height / 2.0f));<br />
<br />
} <br />
<br />
private void PaintImage()<br />
{<br />
if (bitmap != null)<br />
{<br />
float widthZoomed = panel1.Width / Zoom;<br />
float heigthZoomed = panel1.Height / Zoom;<br />
<br />
if (widthZoomed > 30000.0f)<br />
{<br />
Zoom = panel1.Width / 30000.0f;<br />
widthZoomed = 30000.0f;<br />
}<br />
if (heigthZoomed > 30000.0f)<br />
{<br />
Zoom = panel1.Height / 30000.0f;<br />

<br />

Rectangle drawRect = new Rectangle(<br />
(int)(viewPortCenter.X - wz2),<br />
(int)(viewPortCenter.Y - hz2),<br />
(int)(widthZoomed),<br />
(int)(heigthZoomed));<br />
<br />
<br />
myBuffer.Graphics.Clear(Color.White);
<br />
myBuffer.Graphics.DrawImage(bitmap, this.panel1.DisplayRectangle, drawRect, GraphicsUnit.Pixel);<br />

}<br />
<br />
protected override void OnResize(EventArgs e)<br />
{<br />
setup(false);<br />
base.OnResize(e);<br />
}<br />
<br />
private void panel1_Paint(object sender, PaintEventArgs e)<br />
{ <br />
PaintImage();<br />
}<br />
<br />
private void panel1_MouseWheel(object sender, System.Windows.Forms.MouseEventArgs e)<br />
{<br />
Zoom += Zoom * (e.Delta / 1200.0f);
if (e.Delta > 0)
viewPortCenter = new PointF(viewPortCenter.X + ((e.X - (panel1.Width / 2)) /(2* Zoom)), viewPortCenter.Y + ((e.Y - (panel1.Height/2)) / (2*Zoom))); <br />
this.panel1.Invalidate(); <br />
}<br />
<br />
private void panel1_MouseDown(object sender, MouseEventArgs e)<br />
{<br />
if (e.Button == MouseButtons.Left)<br />
draging = true;<br />
}<br />
<br />
private void panel1_MouseMove(object sender, MouseEventArgs e)<br />
{<br />
if (draging)<br />
{<br />
viewPortCenter = new PointF(viewPortCenter.X + ((lastMouse.X - e.X)/Zoom), viewPortCenter.Y + ((lastMouse.Y- e.Y)/Zoom)); <br />
panel1.Invalidate(); <br />
}<br />
lastMouse = e.Location;<br />
}<br />
<br />
private void panel1_MouseUp(object sender, MouseEventArgs e)<br />
{<br />
if (e.Button == MouseButtons.Left)<br />
draging = false;<br />
} <br />
}
but in runTime, when i panning image in my control, it has a flicker and very bad result, for solve this problem, in top of above code, i define a new class that derived from Panel and wrote this code :
public class overRidePanel : Panel<br />
{<br />
protected override void OnPaintBackground(PaintEventArgs pevent) <br />
{<br />
<br />
}<br />
}
then modify my panel to instanciate from new overRidePanel class, as u can see in above code, i was override OnPaintBackground event only, then run my app, it gave me best result and remove flicker when i panning and zomming my images in app, but when my app run, the ImageMap does not have a any image to display it, and my control in runTime does not display white color correctly(it show back of the my app and not good for me), i want when i start app, it is white color before selecting image, but how to do ?
thanks

Hello,
I've been trying for while now to upload a picture and get it to be displayed in an Image control. I still can't get the code right. I used
FileUpload1.PostedFile.SaveAs(filepath);
Image1.ImageURL = filepath;
after performing the necessary checks. The ASP.NET debugger says the path format is not supported. I need help.
Thanks.

You need to store it within your web app, then your imageURL needs to be a URL to the file, not a path on the file system. Server.MapPath is how you convert them,

In .Net, Text box control is in square shape. I would like to change the shape of the control to Circle from square shape. Is it possible to customize the shape of Textbox control as circle?
Thanks in advance.

By overriding OnPaint method

Not really, no. The textbox in windows sucks because it paints itself often outside it's paint event. It can be done, but it's hard work. Why not just draw a circle of white around the edges of a textbox with no border ?

*grin* for any other control it would probably be right. It still is, excepting that you need to handle a bunch of other events and force repaints, and you'll never get rid of the flicker.

Thanks 
Meanwhile, was the reply for the earlier thread (disable copy paste) correct?

Yes, it looked like it to me. I'd have to try it to see if it worked, but that's what I had in mind.

Thanks for your reply. But how to draw circle in windows form design? Please guide me.

The FillEllipse method of the Graphics class. You'd create a control with a textbox and a circle drawn around it.
