Hi there.
I'm created a borderless window, on which I put 8 panels containing my custom window border. I want the window to be resized when the user clicks+ drags from the right border. I created 3 event handlers for the right border panel...mousedown, mouseUp and mouseMove. On mouseDown, a flag is set and I get the location of the click. On MouseUp I unset the flag. On mouse move I do the following:
<br />
if (this.resizeRDown) <br />
{<br />
int Xdiff;<br />
Xdiff = e.X - this.ResizeRXY.X;<br />
this.Width = this.Width + Xdiff;<br />
} <br />
But the resizing is acting very weird...making the window a single pixel wide.
Can anyone give me a hint on this(or an article for that matter) that can help out.
Thanks

What does the debugger say when you examine e.X and ResizeRXY.X? What values do they have at runtime?
Maybe you just calulate them wrong.

Well, that's what I actually prompted me to write here. I discovered that hovering was affecting this so I handled mousehover, so that it would unset the flag. It improved, but still acting kind of funny.
Well...for XDiff..the value is small.
What I want to know is whether e.X, e.Y (mouse location) is the coordinate with respect to the top,left (first location of window) or with respect to 0,0 of screen?

Depends on what e is. If it's a point from Cursor.Position, then MSDN says: A Point that represents the cursor's position in screen coordinates.
But you can use the PointToClient method to convert them into client coordinates.

Hi,
the code seems good at first glance but some parts are missing to clear this out. I assume you are setting ResizeRXY not correctly. Be beware of the affect that the X and Y coordinate of the MouseEventArgs are relative to the control which generated the event in relation to its parent (to the whole screen when working with a Form).
I quickly put together the following (where panel1 is a Panel docked to the right of a Form - but it shouldn't matter what kind of control it is):
private Point _resizePoint;
private void panel1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{
_resizePoint = new Point(e.X, e.Y);
}
private void panel1_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e)
{
_resizePoint = Point.Empty;
}
private void panel1_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e)
{
if (_resizePoint != Point.Empty)
{
this.Width += (e.X - _resizePoint.X);
}
}

Hi
I am beginner at C#.
I need to create two classes which will represent two picture models(like JPG and bitmap).It should look something like this
class JPGImage
{
..............
}
class BMPImage
{
..............
}
I don't know how to describe this classes.
In winForm I need 2 panels where I'll put this 2 models.
Can you help me with this?
Thanks

It depends what you want to do.
In .NET, you use the Bitmap class to handle not only BMP images but also GIF, PNG and JPG - so from most points of view there would be no difference as to what members you would use to describe them.

OK thanks,
Does it mean that I can inherit from Bitmap class my
class like this :
class JpgImage : Bitmap
{
....
}
and create object JpgImage?
Which methods I can use for working with my class (class JpgImage)?

No. the Bitmap class is sealed, which means you can't inherit from it.
You'd either need to use the Bitmap class, entirely write your own JpgImage class or use a mixture (a JpgImage class which uses a Bitmap instance and its methods)

Thanks, i am starting to understand this.
Using this mixture should look like this:
Image JpgImage= new Bitmap("image1.jpg");
am I right?
|
|
|
|
|
I acutually thought about something like this:
class JpgImage
{
private Bitmap jpg;
public JpgImage(string file)
{
jpg = new Bitmap(file);
}
}

I'm not sure I understand this,but it is ok.
Now with jpg I can create drawing(like rectangular or elipse,line etc),am I right?
Thank you again,you have helped me a lot.
Sorry for bothering you.

No you can't.
Sorry no offense, but I think you need to read a book about C# and take a lot of practice to understand how this stuff works

whats the point though? they all load in exactly the same way from Bitmap, no advantages / disadvantages from what you can do with them - just use the Bitmap class, or if you have to
public enum ImageType
{
JPG = 0;
PNG = 1;
etc
}
class Image
{
public bitmap itsBitmap;
public ImageType itsFormat;
}

hi guys,
how can i set the file that i create using c# (FileStream) to be automatically hidden or read-only? i dont want the client users to have access to that file that is why i want to hide it..
if there's a better way of doing this, im open to suggestions.. tnx in advance!

I think you have to use the File object in the System.IO namespace.
It would go something like:
<br />
File.SetAttributes(path, FileAttributes.Hidden);
See the following URL for reference:
File.SetAttributes Method
Hope this helps.

Thanks for the immediate reply.. 
here's a follow up question. is it possible for the folder which contains the file to set its attribute also to hidden?
|
|
|
|
|
Have you looked at the DirectoryInfo object in the System.IO namespace?
It also has Attributes member.
Your code would be something like:
DirectoryInfo di = new DirectoryInfo(@"c:\Test");
di.Attributes = FileAttributes.Hidden;
Hope this helps.

Hello,
is it possible to create a .NET DLL (using C#.NET or C++.NET) that exports functions in C-style?
In VC++ we can use extern "C" __declspec(dllexport) for that. And in C#.NET or C++.NET?
Thanks in advance and best regards
Dominik

<code>__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

All public marked types are avalible outside your DLL in .NET
Q:What does the derived class in C# tell to it's parent?
A:All your base are belong to us!

Thanks for your reply. How do I mark a type to be public? Note that I want the functions to be exported in C style, i.e. the other DLL won't have anything to do with .NET.
Best regards
Dominik

Works perfectly with C++/CLI. Here's some sample code:
extern "C" int __declspec(dllexport) Load(int *link)
{
Debug::Print("Load(int*) called");
...
}
