Dear spif2001
I mean the user resize my user control at form designer, not from the propertygrid.
|
|
|
|
|
try this:
Size s;
public AButton()//derived from System.windows.forms.button
{
InitializeComponent();
s = base.Size;
}//constructor
protected override void OnSizeChanged(EventArgs e)
{
base.OnSizeChanged (e);
base.Size = s;
}

The ControlStyles[^] enumeration has some elements to specify fixed width or height.
You usually set these control styles in the constructor of your control using SetStyle().
Furthermore, the actual sizing of the control can be influenced by overwriting Control.SetBoundsCore[^].
I think there are a few examples on MSDN for this, but the links above should get you started.

Even this method is not elegant as i expect, but yeah it works as i expect. Thank a lot. ^^

It is possible to do this from within a window.forms app, display some kind or message, and then cancel the action?
I need to prevent the user from inadvertly shutting down/logging off unless they are sure they wish to stop my app from running.
Thanks in advance.

Take a look at the Microsoft.Win32.SystemEvents class.
It has events for this.

hi
I'm a Korean student.
I'm studing C# and image processing.
I am reading a book, the book's name is GDI+ Programming wrote by you.
I'm studnig 16bit RAW image file.
But I did'nt display on screen.
How can i do?
please help and detail information.
-----my programming source is here -----
FileStream fs = File.Open(strFileName, FileMode.Open, FileAccess.ReadWrite, FileShare.ReadWrite);
BufferedStream buf = new BufferedStream (fs);
BinaryReader r = new BinaryReader(buf);
Bitmap bitmaps = new Bitmap (_Define._ImageWidth, _Define._ImageHeight, PixelFormat.Format16bppGrayScale);// .Format48bppRgb);
BitmapData bmData = bitmaps.LockBits (new Rectangle(0, 0, _Define._ImageWidth, _Define._ImageHeight), ImageLockMode.ReadWrite, PixelFormat.Format16bppGrayScale);
bitmaps.UnlockBits (bmData);
UInt16 *p = (UInt16 *)(void *)bmData.Scan0.ToPointer();
UInt16 swap;
int nTotal = _Define._ImageHeight*_Define._ImageWidth;
byte [] data = new byte [nTotal];
try
{
int nPer = nTotal / 10;
int nCnt = 0;
for(int y = 0; y < nTotal; y++) // 원본을 로드하기위한 For문...
{
if (y%nPer == 0) {
pLoading._Percent = nCnt;
nCnt += 10;
pLoading.Refresh ();
}
swap = (UInt16)(r.ReadInt16 ());
*(p) = swap;
p++;
}
}
catch(Exception fo)
{
MessageBox.Show(fo.ToString());
}
// m_pPanel is View
MDProcess.ImageObject pImage = new ImageObject (m_pPanel);
pImage._ImageName= strFileName;
pImage._rcBound = InitImagePT (iFiles);
pLoading._Percent = 100;
pLoading.Refresh ();
m_alImageList.Add (pImage);
pLoading._Counter = i;
pLoading._Total = alFiles.Count;
pLoading.Refresh ();
bitmaps.Dispose ();
fs.Flush ();
buf.Close ();
fs .Close ();
r.Close ();

Hi everyone
In the .NET Compact Framework (C#) I have created a TCP server socket using BeginAccept. After the connection is established (EndAccept) I use BeginReceive for asynchronous data receive. When the program exits the socket will be closed, but the thread: System.Net.OSSOCK.recv is hanging and the program after the exit still exists and is locked.
How can I terminate the asynchronous reading before closing the socket?
Thank you for any help.

Hi all 
I have a custom usercontrol in my window form "frmsett.cs" .
"initializecomponents" of "frmsett.cs" initialises usercontrol
This usercontrol is derived from a base component class.
Usercontrol populates printer informations.
we populate default printer related informations to usercontrol through Pinfo() method (a function in base component class )
Pinfo() invokes getinfo()(another function in base component class ) using methodinvoker and asynccallback
My "basecomponent" class definition starts with
[ClassInterface(ClassInterfaceType.None), ComVisible(false)]
when i call frmsett.showdialog() Applcation is developed and works perfectly in .NET framework 1.1
Then I installed .NET framework 1.1 SP1
Here the problem begins. When application executes ShowDialog(Only at first call) It hangs for some minutes (5-15 mins) before showing the dialog "frmsett" . If we clicked second time it will display the screen immedialtely.
Anyone come across this type of issues???
Is there any problems asynccallback with methodinvoker in .NET fx1.1 SP1
What is the reason for this problem in .NET fx1.1 SP1???
Thanks a lot for any tips !!!!
Regards

Hi,
How to have the SetItemData and GetItemData property like in MFC listview in
C# Listview ???
Any help will be appreciated.

Check the ListViewItem.Tag property. You can store anything in there, be it an int or a reference to a big object.
If you want to store more than one object, make a little class with public methods for each object, and then store a reference to that object in the Tag property of each item.

In C#, how to change/increase the size for a byte array buffer to be sent over a tcp stream?
on the server side, i have something like this:
while(i != 100)<br />
{<br />
streamWriter.writeline("data");<br />
}
Now, on the client side, i saved every data sent to me. However, only half or so of the data is being sent, the last line in my data.txt file says "unable to read data from the transport connection". And i think it has something to do with the buffer size. So i need to increase it...
THanks for the help.

hi,
what is the API or classes in c# which used to create a new folder ???
Thanks
|
|
|
|
|
Hi best_students,
We can use Directory class which is avaliabe in System.IO namespace for creating new folder. This class provide static methods for doing this.
string path =@"C:\Training\Test";
if(Directory.Exists(path))
{
}
else
{
DirectoryInfo drinfo = Directory.CreateDirectory(path);
}
Guess this will help you.
Thanks

Ok, so I have a number of ‘modes’ for a control I wrote (List View: Detail, Large Icon, and so on). In the designer it is convenient to have an enumerator drop down, consisting of these modes, which a user can select. However, each mode is actually a subclass. So, I was wondering if there is some cool and/or strange way to have an enumerator that contains all subclasses found in the assembly/dlls. This would allow someone to add a new subclass with out also editing the enumerator containing the names of all the subclasses. Yes/No/Thoughts?

It is possible to do this using Reflection. Use the GetTypes() method on the Assembly class, iterate through the types and filter subclasses using the Type.IsSubClassOf() function.

Does anyone know if it's possible to provide a command line switch to make the .NET framework install silently ? Also, does anyone know where ( presumably in the registry ) to check what versions are already installed ?
Thanks

No it's not (as far as I know, but I already researched this before.)

Check the folders in C:\Windows\Microsoft .NET\Framkework\v1.xx.xxxx. 1.1.4322 is 1.1 SP1, for example... and 1.0.3705 is 1.0 SP1 (not really sure on that one, but Heath mentioned it in this same forum some days ago.)

Please suggest how to convert DateTime.Now to FILETIME structure format?
Sandeep Naik

Hi Sandeep
Guess you can use DateTime.Now.ToFileTime(); method.
Thanks
SGS

DateTime.Now.ToFileTime() returns long.. FILETIME is structure. Pls let me if you have someother idea
