hi
try out this class System.Windows.Forms.ControlPaint
|
|
|
|
|
Thankyou but unfortunately I did have a bash at that and could not resolve it. That class seems to work well with everything bar text boxes!
Thankyou for the idea though.

Hello 
I've got a problem ... as you can imagine ...
I have a WinForm with MaximumSize defined, and MaximizeBox enabled ...
My problem is that when user click on Maximize box, the winform got upper-left corner of the screen, and take the maximize size as defined, it's very weird ...
Is it possible to force the form centered when MaximizeBox is clicked ?
How to override this event ( MaximizeBox clicked ) ?
Thanks in advance for your help.
Sebastien.

Hello
There is no Maximized event to override. Instead try overriding SizeChanged event.
Something like this:
SizeChangedHandler(params...)
{
if(WindowState == Maximized)
{
if(Height > Screen.PrimaryScreen.WorkingArea.Height)
{
Top = 0
}
else
{
Top = Screen.PrimaryScreen.WorkingArea.Height / 2 - Height / 2; //To center the Form vertically
}
if(Width > Screen.PrimaryScreen.WorkingArea.Width)
{
Left = 0;
}
else
{
Left = Screen.PrimaryScreen.WorkingArea.Width / 2 - Width / 2; //To center the Form horizontally
}
}
}

As you said ur winform in MaximumSize then so u want ur winform in always maximized state right.. use Form's MaximizeBox property to disable Maximize button.
this.MaximizeBox = false;
Hope this helps u..

Hi!
I'm building a big xml string with a for loop and it takes veeeeeeeeeeeeeery much to complete this process. Later on I load it in an XmlDocument and save it in a file. This last thing takes no time.
The loop is something like:
<br />
string xml = "<Top>";<br />
for (int i=0; i < <ArrayList>.Count; i++){<br />
<br />
xml += "<Something>";<br />
xml += bla bla;<br />
xml += "</Something>";<br />
xml += <Object>.ToXml();
...<br />
...<br />
<br />
}<br />
xml += "</Top>";<br />
I know than the process may not be linear in time, but is there any known way to speed up this proccess? When the thing gets big (2MB xml file) it's really annoying to wait tons of minutes for this to save.
Thanx for any help!

For this you should use the StringBuilder Class.
Here I made a Method wich gives back a string.
public string CreateText(string[] textarray)
{
if(textarray != null)
{
StringBuilder lsb_Format = new StringBuilder();
for(int x=0; x < textarray.Length; x++)
{
lsb_Format.Append(textarray[x]);
}
return lsb_Format.ToString();
}
return "";
}
All the best,
Martin

hi,
Y dont u directly write it into file?
By adding string it consumes much more memory, try using StringBuilder.
Its available in System.Text namespace.

How can i use RowFilter Property of DataView in C#?
|
|
|
|
|
RowFilter is used when you want to display some but not all rows of datatable based on some criteria. This criteria is specified in RowFilter. It is similar to that of using WHERE clause in your SELECT query.

See this example:
ArrayList arrayList = new ArrayList();
arrayList.Add(1);
arrayList.Add(2);
arrayList.Add(3);
DataTable dataTable = new DataTable("Table1");
dataTable.Columns.Add(new DataColumn("Column1", typeof(int)));
foreach(int i in arrayList)
{
DataRow dataRow = dataTable.NewRow();
dataRow["Column1"] = i;
dataTable.Rows.Add(dataRow);
}
this.dataGrid1.DataSource = dataTable;

Hi,
I have a big solutions which includes many c# projects and c++ projects. Some c++ project use the dll files generated by the c# projects. Now I begin to migrate the whole solution to 64-bit platforms. After setting the project, I found all the c# projects in this solution can not generate the expected dlll files.
I am a little confused. Could you help me if you are familiar with this?
Thanks a lot.

As far as I know, there is no 64 bit compiler for C# or C++.NET. But for C++ (unmanaged) you can use for example Intel C++ Compiler.

I'm currently working on a monitoring system for tank overflows. I am using C#.net on a windows CE. How can I read and write to IO ports on Windows CE? What dll should I use?

Namespace: System.IO.Ports

Hope this helps u

Hello,
Thanks for replying to my message. I can already read and write to serial port. My concern now is how to read and write to ports other that serial ports. Like if I want to write to an IO port with address (0x378) and I want to write the data 0xFF; something like that.
I tried to add to my project the following codes,...
[DllImport("inpout32.dll", EntryPoint = "Out32")]
internal static extern void Out32(short PortAddress, short data);
[DllImport("inpout32.dll", EntryPoint = "Inp32")]
internal static extern short Inp32(short PortAddress);
public void PortOut(short address, short data)
{
Out32(address, data);
}
public short PortIn(short address)
{
Inp32(address);
}
but it is not working, maybe I used the wrong dll. By the way I am using WindowsCE and VSC#.NET 2005 version.Can you give me any ideas or maybe sample codes on how to do this. Thanks
