Hello
I don't think I fully understand your question, but if you want to browse through all properties of a certain type -not instance- and get their names then call Type.GetProperties() method. If you have a certain object of that type, and you want to check the value of that property, then get the PropertyInfo and call PropertyInfo.GetValue() method supplying it with the object you want to check for that value.
I hope this was helpful.

Hello,
Is your parent form a Standard System.Windows.Forms.Form?
If not, and you would like to get access to a user property, you would have to cast it to your userform.
UserForm userform = this.ParentForm as UserForm;
if(userform!=null)
{
userform.??? //Do youre stuff!
}
Hope that helps you!
All the best,
Martin

Hello,
Are you getting an Exception during runtime, or is youre code not compilable?
|
|
|
|

i hope my previous solution should work. here anothr for you
pass your parent form object in the child form and store it like;
object parmObj = parentObject;
and now access parent form public methods/variable by type casting it by ur parent form class name. ie.
((ParentForm)parmObj).Variable;<br />
((ParentForm)parmObj).Method();

That is not practically possible. That would require that all the computers use the same resolution, has the same windows theme, use the same browser, open the browswer window with the exact same size, have the exact same settings for browser toolbars, have the same setting for browser text size, et.c.
I would rather go for displaying an image of the teachers browser instead.

The best way to do this would be to embedd IE in your app and then control it from there. As someone else said, you cannot guarentee that everyone sees exactly the same thing, but you can host a web browser and interact with it.
And it would use a lot less bandwidth than sending images of the central PCs browser.

I'm trying my popup system by using the win32 call:
[DllImport("user32", SetLastError = true, CharSet = CharSet.Auto)]
public static extern int AnimateWindow(int hWnd, int dwTime, int dwFlags);
instead of myPopup.Show().
However when I use AnimateWindow al the child control disappear!
Some reappear when I click on the winodws.
Even more puzzling, I been checking the child control with the debugger:
they are there, visible, with the correct bounds (and parent!!)
Hey, what's happening!
Any ideas?

Solved with a call to myPopup.CreateControl()

Actually they are easily converted to Bitmaps several ways. A simple one
Bitmap MyBitmap = (Bitmap)MyPictureBox.Image;

You can achieve this effect by calling a special version of Graphics.DrawImage().
Create a Bitmap in the size of your cropping area.
Then get yourself a Graphics object to draw into this bitmap using Graphics.FromImage().
Using this Graphics object you draw the original image into the new bitmap in a way that the top left corner of the crop area is painted to the top left corner of your new bitmap.
Don't forget to dispose of the Graphics object afterwards or you'll create a resource leak.

row is already get selected by default behaviour of datagrid.
for any special color you can use
myDataGrid1.SelectionBackColor Property
and to access current row you can use
myDataGrid1.CurrentRowIndex
