Re: Strange problems with DataGridView with Panels in the heading

I solved issue #1. The problem was probably that the scrollbar belongs to the Control it is inheriting and the DataGridView doesn't know if the scrollbar is present or not. If I let the Table-class inherit DataGridView instead of Control then issue #1 goes away.

Did you try DrawToBitmap()[^] method?

I tried the following in the webBrowser1_Navigated handler, but the image is blank:

Bitmap bitmap = new Bitmap(webBrowser1.Width, webBrowser1.Height);
webBrowser1.DrawToBitmap(bitmap, new Rectangle(new Point(), webBrowser1.Size));
bitmap.Save("C:\\test.jpg", ImageFormat.Jpeg);
bitmap.Dispose();

any ideas?

thanx

last time I did that with a WebBrowser, the image was black, not blank!?
And no, I haven't found a solution yet (I haven't been looking very hard either).

Hi,

Apparently using DrawToBitmap on WebBrowser control works only for some sites. [^]
I also found this[^], which might help you. But i haven't tried it yet.

Components written by a third party; that is to say not by the provider of your development environment (e.g. Microsoft) and not by you. How you integrate them into your program depends entirely on what sort of components they are and what they are designed to do.

Example of what? I just explained that third party products are made by other people, I have no idea which ones you are interested in. There are thousands on the internet for everything associated with computing.

need suggestion for the code

Project 1

I have four classes

class1
this contains the variables, properties and constructors
suppose

private string abc;

Interface2
This contains interfaces

void a1();

class3
this will have function definitions. basically this will contains functions to do the
database interactions

public void a1()
{
 // code.....
}

class4
this will inherit Interface 2 and will override the definition.

public void a1()
{
 class3 a = new class3();
 a.a1();
}

Project 2

class5
this will have function

public static Interface2 Getclass4_Details()
{
    return new class4();
}

Project 3

In the form button click

i am doing

Interface2 Obj = null;
Obj = project2.class5.Getclass4_Details();
obj.a1();

I am approaching in the above way to do database interaction. Am I approaching i the right direction ?

I suspect not, but it is difficult to understand what you are trying to achieve. The only thing I would say is that this looks extremely complicated; are you sure you need so many classes and interfaces?

I would suggest looking at some of the links here[^]. It is not a simple matter of a few lines of code, you will need to study the subject in some depth to get a workable solution.

It's not immediately clear to me why you need class4 as well as class3. What value do you gain by having class4 in there instead of having class3 implement interface 2? Class 4 seems to do nothing but bucket-pass calls straight on to class 3.

By the way, better names might make the example a bit easier to understand.

Reason - I am implementing the multiple inheritence concept in class4
by overriding the function

Both classes are in the same assembly, I too see no point in having class4 there, btw i think you should subclass Class3 instead of creating a new instance in the function in class4.

Good morning.

I have an app which uses the Windows Media Player control, but I am using customized buttons instead of the player controls.

I wan to increase and decrease the volume with a TrackBar control, but I am not sure how to access the volumn properties of the axWindowsMediaPlayer1.currentMedia.

Any suggestions? Thnak you, WHEELS

Re: C# VS 2008 3.5 Controlling volume with TrackBar

Covean13-Jan-10 4:25

You can read and write the volume by accessing the volume property of the media player settings.

axWindowsMediaPlayer1.settings.volume = (range 0 - 100)

Hope that helps (not tested)!
