ResultForm.richTextBox1.Text += "Return Result # " + (beginResultPage + i + 1).ToString() + "\r";<br />
ResultForm.richTextBox1.Text += gresult.resultElements[i].title + "\r";<br />
ResultForm.richTextBox1.Text += gresult.resultElements[i].snippet + "\r";<br />
ResultForm.richTextBox1.Text += gresult.resultElements[i].URL + "\r\r";<br />
Hi
from the codes above, i want to bold some of the results that is recieved through the richTextBox control in the form.
For eg, if i want to make bold the title that is produced using this line of code,
ResultForm.richTextBox1.Text += gresult.resultElements[i].title + "\r";
What do i need to add in to ensure that the title is in bold?
I tried with FontStyle.Bold but i can't seem to get this right.
Help!,

I would try selecting the relevant text then:
richTextBox.SelectionFont = new Font(richTextBox.SelectionFont, FontStyle.Bold);

Problem: Hidden text not being set for RichTextBox initialized in an MDI Child Form.
Initialize a RichTextBox in an MDi Child form:
RichTextBox rtb = new RichTextBox();
rtb.SelectedRtf is initially set to empty string. Expected result is (rtb.SelectedRtf == "{\\rtf1\\ansi\\ansicpg1252\\deff0\\deflang1033\\uc1 }\r\n").
Also set rtb.SelectedRtf = @"{\rtf1\ansi " + "visibleText" + @"\v " + "hiddenText" + @"\v0}";
The result is rtb.Text = "visibleText". (rtb.Text should be "visibleTexthiddenText").
i.e. the hidden text is not being updated when rtb is initialized in an MDIChild.
Anyone know the cause/workaround? Your help is appreciated.
Thanks, B

Hi
Is there a way to change the Form look so it will have round corners - or change it to a shape that I like? Draw it myself?
Is there a way to change the controlBox look as well - set different colors and different buttons?
I know that in c++ it's possible
thanks in advance

Of course you can do it!
For example, in the Form1_Paint() handler you could use:
System.Drawing.Drawing2D.GraphicsPath gPath = new System.Drawing.Drawing2D.GraphicsPath();
System.Drawing.Rectangle formRectangle = this.Bounds;
gPath.AddEllipse(0, 0, formRectangle.Width, formRectangle.Height);
this.Region = new System.Drawing.Region(gPath);
This will turn your form into an ellipse.
Just use your imagination

By the way.
Usually, when I want to drag a winodw, I click and hold the ControlBox and drag the window.
How can make move the window when I click and hold on a place in the window itself?

Here is a code which might helps you.
I used the methods in a basic form and my inherit form called the public method. (Just in case you are wondering why it's public)
private Point _startDragPoint;
private System.Timers.Timer TimerMovePad;
this.MouseUp += new System.Windows.Forms.MouseEventHandler(this.yourFormMouseUp);
this.MouseMove += new System.Windows.Forms.MouseEventHandler(this.yourFormMouseMove);
this.MouseDown += new System.Windows.Forms.MouseEventHandler(this.yourFormMouseDown);
public void MovePadMouseDown(System.Windows.Forms.MouseEventArgs e)
{
_dragModeEnabled = true;
_startDragPoint = new Point(e.X, e.Y);
}
public void MovePadMouseMove(System.Windows.Forms.MouseEventArgs e)
{
if (_dragModeEnabled == false)
return;
MovePad(e);
}
public void MovePadMouseUp(System.Windows.Forms.MouseEventArgs e)
{
if (_dragModeEnabled == false)
return;
_dragModeEnabled = false;
MovePad(e);
}
private void MovePad(System.Windows.Forms.MouseEventArgs e)
{
if(TimerMovePad == null)
{
this.TimerMovePad = new System.Timers.Timer();
this.TimerMovePad.Interval = 100;
this.TimerMovePad.Elapsed +=new System.Timers.ElapsedEventHandler(TimerMovePad_Elapsed);
}
if (TimerMovePad.Enabled == false)
{
TimerMovePad.Enabled = true;
}
if(_movementok == true)
{
_movementok = false;
int delta_x = e.X - _startDragPoint.X;
int delta_y = e.Y - _startDragPoint.Y;
this.Location = new Point((this.Location.X + delta_x), (this.Location.Y + delta_y));
}
}
private void TimerMovePad_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
TimerMovePad.Enabled = false;
_movementok = true;
}
private void yourFormMouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{
MovePadMouseDown(e);
}
private void yourFormMouseMove(object sender, System.Windows.Forms.MouseEventArgs e)
{
MovePadMouseMove(e);
}
private void yourFormMouseUp(object sender, System.Windows.Forms.MouseEventArgs e)
{
MovePadMouseUp(e);
}
Hope it helps!
All the best,
Martin

hi..
how to set a button as default..
that when i press the Enter button, the button event should occur
regards,
hiremath

I don't know how you can set a button as default... But instead of this, you can set the KeyPreview property value "true" and add handle the KeyDown event of the form, and call the same method that you call with the button click event.

Hello,
I think the AcceptButton property is what you are looking for.
yourform.AcceptButton = yourbutton;
All the best,

Did you notice that CancelButton appears on Intellisense and the property grid at design time but AcceptButton doesn't appear on either both.

Forgive me if this has been covered somewhere before, but searching here for "COM Interface" or "COM Object" did not return anything interesting...
I have an out-of-proc COM server. It has been around for a little while and has been used by other (native) applications without issue. However, I now have a C#-based component using my server. When this happens, the memory requirements for my server start to climb at a rate that matches the times when the C# application is making periodic calls into the server. This is only being observed on two particular machines at a particular installation. The footprint can grow to more than 400MB(!) over its normal size of about 28-48MB.
The particular method being called returns data via out parameters. Actually, the method being called takes a series of VARIANT objects as in parameters and returns a series of VARIANT objects as out parameters, and different data can be returned depending on how the method was called. In this case, the data being returned is being returned as a BSTR-in-a-VARIANT.
This has never been an issue before. Oddly enough, this issue is not being reported anywhere else and cannot be recreated on my development system. I am thinking it may be connected to the C# code's memory management, because if that client disconnects (but remains running), the memory footprint slowly starts to reduce back to its normal size, making me think that that GC invocations are then taking place and recovering resources (the GC can also run at idle periods, not just on demand, right?). The COM server's implementation does not do anything with memory that would explain this, although I find it odd that the memory growth is being seen in the server and not the client. No performance impact is being observed, either.
Does anyone have any ideas as to why this may be happening? So far, this is the first .Net application that is using my server, and at the risk of sounding conceited, I have no reason to believe that the problem is on my end because of the past history of use with the server. Both the server's logging and examination under the debugger do not show any unnecessary allocations.
Has anyone experienced any strange memory-related behavior when working with an out-of-proc COM server? One special thing about this interface is that it uses a callback interface, which is optional. This particular C# client is not using the callback interface, passing the equivalent of a NULL interface pointer. This is an accepted use of the server.
Peace!

If your COM objects are holding session for clients memory use in the server is directly related to the client behavior, otherwise no.

The per-client memory that is allocated is being managed correctly. The reason I think it may have to do with GC activity is because the following has been observed:
1: When the C# portion of the application is made idle (or at least, more idle than normal), memory is slowly reclaimed.
2: If the other application is closed, the memory comes back much faster.
Another reason is because of how BSTRs have to be managed to pass them out-of-proc. When copies are made by the COM subsystem, where is that memory being tracked? If it is showing up in my process, because that is the "side" where it is being allocated, but it coorrelating BSTR on the client-side is not being freed until later on, would that cause what I am seeing?
This is the strangest thing...
Peace!

I would like to create a new instance of a class, but I would like the user to tell me the name of the object they want to create, and the code uses that (stored as a string) name and creates the object.
This is done as a method. This is what I thought about, but it creates it called the name of the variable:
public void createTextBox(string textBoxName)
{
// Create a new text box
TextBox = textBoxName new TextBox;
}
I am going about this all wrong!
OK, what I want to do, is create a DLL, that is for a programming language created with C#, that allows them the make a GUI, they can create different components, how do I do this?

This is not possible, a variable name needs to be hard coded, but you can use an ArrayList to store an unkown number of TextBoxes.
