You're converting Delphi to C# ? Is it Delphi.NET ? Sounds like a rewrite to me....

Yup. Convert - is in fact rewrite.
Project itself is not a vector editor. It's more like Infopath with additional features (one of which is user editable sketches). I was thinking about Ink, but there is a requirement for regions, filled shapes and so on.
Here is what I have in mind (only for .NET WinForms)

Looks like a lot of fun.

Why not take a look at this[^]? You can also find a version of Netron on Sourceforge called Netron Unloaded.

I developed a drawing program.
I use GraphicsPath, now i wantto erase what i drawn. how could i do.
Drawing code is above.
Dim mousePath As New System.Drawing.Drawing2D.GraphicsPath()<br />
Dim SelectRect As New Rectangle()<br />
Dim ps As New Point()<br />
Dim pe As New Point()<br />
Private Sub PictureBomcp1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles pbImage.MouseDown<br />
SelectRect.Width = 0<br />
SelectRect.Height = 0<br />
SelectRect.X = e.X<br />
SelectRect.Y = e.Y<br />
ps.X = e.X<br />
ps.Y = e.Y<br />
pe = ps<br />
If e.Button = Windows.Forms.MouseButtons.Left Then<br />
mousePath.StartFigure()<br />
End If<br />
<br />
End Sub<br />
<br />
Private Sub PictureBomcp1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles pbImage.MouseMove<br />
If (e.Button = MouseButtons.Left) Then<br />
Dim thisform As PictureBox = CType(sender, PictureBox)<br />
Dim g As Graphics = thisform.CreateGraphics()<br />
mousePath.AddLine(e.X, e.Y, e.X, e.Y)<br />
g.DrawPath(New Pen(MyConstants._C, MyConstants._W), mousePath)<br />
End If<br />
End Sub<br />
<br />
Private Sub PictureBomcp1_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles pbImage.MouseUp<br />
Dim thisform As PictureBox = CType(sender, PictureBox)<br />
Dim g As Graphics = thisform.CreateGraphics()<br />
Dim p As New Pen(MyConstants._C, MyConstants._W)<br />
g.DrawPath(New Pen(MyConstants._C, MyConstants._W), mousePath)<br />
mousePath.Reset()<br />
g.Dispose()<br />
End Sub

May I suggest looking at these articles on CodeProject for good ideas on drawing programs:
Draw Tools[^]
Draw Tools Redux[^]
The second article is an extension of the first, both illustrate drawing objects, resizing, erasing, moving, saving to and restoring drawings from disk, etc.

Hi again,
I aim to do a simple eraser for deleting what i draw as mspaint.
I searched CodeProject for erasing code, but i couldnt find.
|
|
|
|
|
In that case, you wouldn't want to use a GraphicsPath to do the drawing, instead just draw on your canvas and implement the erasing code by drawing over existing objects with the background color, which is what MSPaint does.
Sincerely,

Do you know how to sort a listview? If not do some searching there must be a million sources that show how to do it.
However if this is your problem:

hi all,
I am using a datagridview to display data.i am creating a datatable dynamically and set it as a datasource. i am contatenating values of two columns and displaying in a single column. i need to highlight one of the values as a bold text.
i am using VS 2005 with C#.net in windows application.
How can i implement the same?
Thanks in advance. 
Regards
Anuradha

Handle the DataGridView's CellFormatting Event and write code to change BackColor of the value of want to Highlight.

This is my code to save something from a textbox:
StreamWriter msgStreamWriter = new StreamWriter("message.txt");
msgStreamWriter.WriteLine(textBox1.Text);
msgStreamWriter.Close();
is it possible to save different messages and also in different files?
for example,
message1 into notepad1
message2 into notepad2
message3 into notepad3
help please!
Thanks.
|
|
|
|
|
What are message1, message2, message3?
|
|
|
|
|
For example, if a user decides to save the first message "hello" as message1.txt
Second message "how are you" as message2.txt
Third message "Goodbye" as message3.txt
What would the code be?
Because for now all i can do is to save the first message message1.txt. But saving the rest would be overwritting the contents of message1.txt.

I want to subtract the time. For example I have two timing; one is FROM TIME and the other is TO TIME. I want to get the difference of the timing. Is there any option thro' TimeSpan or DateTime
Regards,
LEE

The DateTime structure has a Subtract[^] method.

TimeSpan timeSpan = [firstDate].Subtract(secondDate);
then you can get the diff like
timeSpan.Minutes;
timeSpan.Hour etc.....
Hope that is what you are looking for

I don't know how to do this via code exactly, but what you can do is install the same printer into Windows 4 times and give them each a different name, although each will point to the same physical printer. For each printer set it to use one of the trays. You could then code against each of these printers - so if you require to use trays 1,3,2 print to Printer 1, Printer 3, Printer 2.
Me: Can you see the "up" arrow?
User:Errr...ummm....no.
Me: Can you see an arrow that points upwards?
User: Oh yes, I see it now!

in a textbox i want to get only chracters as input, prevent symbols , to do this i tried a fuction which takes the string in the textbox and check it using Char.isletter() and returns true or false.
But i want to know whether there is any other method with String to do this.
|
|

|

What you're doing is correct. No, there is no method that does the same on an entire string, nor would you want that. By handling the keychanged event and checking char.IsLetter and char.IsControl to set the handled property, you can stop users entering invalid characters in the first place.

Hi
I am trying to compile a workspace using Msdev.exe (Visual Studio 6) .
I am using the command line and want to redirect the output into a rich textbox on my form.
When an error in compilation occur the process is hanged until i stop my application and only then the Msdev is showing the error.
System.IntPtr PrHndle;<br />
Process Prc = new Process();<br />
<br />
Prc.StartInfo.FileName = VS6EXEPath;<br />
Prc.StartInfo.Arguments = WorkSpace + CompileCommandString;<br />
Prc.StartInfo.UseShellExecute = false;<br />
Prc.StartInfo.RedirectStandardOutput=true;<br />
<br />
Prc.Start();<br />
PrHndle = Prc.Handle;<br />
<br />
StreamReader SR = Prc.StandardOutput;<br />
<br />
while (SR.EndOfStream != true)<br />
{<br />
rtbCmdOutput.Text = rtbCmdOutput.Text + "\r\n" + SR.ReadLine();<br />
}<br />
Prc.WaitForExit();
Same code works good with appliaction.
Please help
Have a nice Day

Instead of blocking the thread waiting for output, use an event to listen for output:
Process proc = ...;
proc.OutputDataReceived += OutputDataReceivedHandler;
...
void OutputDataReceivedHandler(object sender, System.Diagnostics.DataReceivedEventArgs e)
{
rtbCmdOutput.AppendText(e.Data);
}
