Hi,
When i create a new form i set its MdiParent value to the main programs form. The problem is when im creating a form from with in that child.
eg main program - form1 - form created from form1
When creating the form, i do:
form obj = new form();
obj.MdiParent = this;
When creating the form from form1, i do:
form obj1 = new form();
obj1.MdiParent = Globals.MainForm;
Globals.MainForm is a static class which ref's the instance of main programs form.
The problem im having is that when clicking away from the form created within form1 - eg: obj1 - i cant un focus the form and go to form1.
Any ideas what could be causing this?
Regards,
Gareth.

Hello,
i came across this interesting article - http://www.codeproject.com/cs/miscctrl/SyntaxHighlighting.asp[^]
The article provides it's own rtb, control, so i was wondering, how do you replace my own rtb controls with the one provided in this article?
I already have a richtextbox on my form which i'd like to keep (because i build my application around that rtb), whilst using the controls provided by this article (for the syntax highlighting feature), how can i do this?
I am not asking for someone to write me a code or full detailed explaination, a quick instruction would be much appreciated. Many thanks in advance for your input.

assuming the replacement kept the same interface as the stock RTB, add the new control into your project's references, add it into the forms includes. replace the type and instantiation of the old RTB with those of the new control. IF the events and properties were changed you'll have to modify your existing code to work with the new interface.

Im not good at C# at all, so i'll try to explain this as clear as possible (from my point of view).
On the sample app provided in the article, it has a form without any rtb in it. BUT, the form us linked to an action form1_Load();
So, i had a look in there and this is the code i saw:
SyntaxHighlightingTextBox shtb = new SyntaxHighlightingTextBox();
shtb.Location = new Point(0,0);
shtb.Dock = DockStyle.Fill;
shtb.Seperators.Add(' ');
shtb.Seperators.Add('\r');
shtb.Seperators.Add('\n');
shtb.Seperators.Add(',');
shtb.Seperators.Add('.');
shtb.Seperators.Add('-');
shtb.Seperators.Add('+');
//shtb.Seperators.Add('*');
//shtb.Seperators.Add('/');
Controls.Add(shtb);
shtb.WordWrap = false;
shtb.ScrollBars = RichTextBoxScrollBars.Both;// & RichTextBoxScrollBars.ForcedVertical;
shtb.FilterAutoComplete = false;
shtb.HighlightDescriptors.Add(new HighlightDescriptor("Hello", Color.Red, null, DescriptorType.Word, DescriptorRecognition.WholeWord, true));
As you can see, the class inside the syntax highlighting textbox library is called to make a new instance called "shtb" and then only after, words to highlight such as "hello" is added to it.
My question orginally was, is it possible to have the ability to highlight text inside rtb (as i type), without creating a new instance such as "shtb", because i already have a rtb on my form. I just want to add the syntax highlighting functionality to the existing rtb box i have.
Did i confuse you guys with what i am trying to achieve? Is this even possible?...

can anyone out there help me out on this please..?

Spend some time to read the code from the article, learn how it works, then decide for yourself whether or not what you want is possible.

i have a Panel with autoscroll = true and some UserControls placed on it on runtime..
the usercontrols when added to the panel are given an OnMouseEnter event in which the some property is set to a proper value:
<br />
public TreeItem ActiveItem {<br />
get { return _activeItem; }<br />
set { <br />
_activeItem = value; <br />
<br />
if(_activeItem.ItemType == ItemType.Person)<br />
lbTreeItemType.Text = "Person:";
else if(_activeItem.ItemType == ItemType.Relation) <br />
lbTreeItemType.Text = "Relation:";<br />
}<br />
}<br />
the strangeness occures when the lbTreeItemType.Text is set.
the panel scrollbars' values are set to 0...
anybody knows why changing some property on a toolstrip resets panel's scrollbars?!..
life is study!!!

k. i switched from toolstrip to menustrip.. and the strange behaviour stopped..
so my only guess is that there is some bug in DockContent from WeifenLuo.WinFormsUI.Docking.dll which I'm using to host these controls..

I'm using an object created from a class that I've called Interval. The class consists of two private members (min and max) of type double and get/set (Min, Max) for each private member. When Min is set it is compared with Max to ensure that Min is less than or equal to Max. This comparison is working at run time but not at design time. At design time the value of Max is the same as I set as default value in the class (private double max = 0) and not the value that is set in the property window in the designer.
I hope someone could help me with this problem.
Thanks in advance

Hi,
I want to store a set of codes in an XML file and read the contents. I want each object to be a item consisting of a name and a code, so that I can put the name in and get the corresponding code out. What's a simple and efficient way of doing this?
I can't use my web.config as there may be many codes.
Thanks

Assuming your object value can be rendered as a string, XmlTextWriter and XPath are your simplest tools. A simple WriteElementString to write each object with the element name for your object name, and the element value your object value. Then for reading you load the file into an XmlDocument, and use an XPath query for the element with your object name, and get its value.
public static void Write()
{
using (XmlTextWriter tw = new XmlTextWriter(myFileName, System.Text.Encoding.Default))
{
tw.WriteStartDocument();
tw.WriteElementString("ObjectName", "ObjectValue");
tw.WriteEndDocument();
}
}
public static void Read()
{
XmlDocument xdoc = new XmlDocument();
xdoc.Load(myFileName);
XmlNode myObject = xdoc.SelectSingleNode("ObjectName");
string myValue = "";
if (myObject != null)
myValue = myObject.InnerText;
}

I have written a component called PlotPanel which inherits from System.Windows.Forms.Panel. When the control is used in the design window the default constructor "this.plotPanelReal = new PlotPanel();" is generated in "Windows Form Designer generated code". I want to use an overloaded constructor instead: "this.plotPanelReal = new SEA.PlotPanel(nbXMin, nbXMax, nbYMin, nbYMax);" (nbXXXX is number boxes which inherits from TextBox).
If I just change the row "this.plotPanelReal = new PlotPanel();" in "Windows Form Designer generated code" to "this.plotPanelReal = new SEA.PlotPanel(nbXMin, nbXMax, nbYMin, nbYMax);" it works until I do some changes in the designer then row is changed to the default constructor again.
If I just leave the row "this.plotPanelReal = new PlotPanel();" in "Windows Form Designer generated code" and instead place "this.plotPanelReal = new SEA.PlotPanel(nbXMin, nbXMax, nbYMin, nbYMax);" in, for example, the constructor of the main class the arguments is not making any difference. The reference of the number boxes is not passed to the PlotPanel object.
Please, help needed

Don't change the Windows Forms Designer generated code. There is a big warning message telling you not to.
If you instantiate the object in the constructor of the form the code in the InitialiseComponent method will replace your version with its own. This is evident if you step through the code with the debugger.
Two options:
* If you want to keep using the designer for this control then you should be passing this information as properties to the control rather than in the constructor.
* If you don't mind the loss of the designer control over this control then do it all manually in the constructor (or your own method called from the constructor)

I have made a Rss Reader (Windows app) - it takes one Url(i.e. watever.com/rss.xml) and reads its contents. But its not working with those sites which have authentication (e.g. those sites need userid/password to enter and read Rss feed).
My question is how can I authenticate to a site thru my application or thru programming ?
I need some help.

Depends on the kind of authentication the site requires, if the site uses cookies to set authentication, then use cookies in your code.

It requires http authentication.

Hi all,
This is the scenario: the user is able to initiate some process by selecting some data from a form, dragging it and dropping it onto another independent form. I want to add the option of introducing a context menu if the user were to use the right mouse button to do the drag&drop just before said process is initiated (using the context menu, the user can define how that process behaves).
My initial attempt looks something like this:
<br />
...<br />
private void HandleDragDrop()<br />
{<br />
doSomething<br />
...<br />
contextMenuStrip.Show();<br />
...<br />
doSomethingElse<br />
}<br />
Two problems with this:
1. contextMenuStrip.Show(); by itself doesn't appear to be blocking. It does display the context menu but then goes ahead and executes all subsequent commands without waiting for user input.
2. The selection made is handled elsewhere using a standard Click event handler so even if I were able to stop the program to await user selection, I wonder if the context would leap from the Click event handler back to the statement immediately following the .Show() command. Sounds too easy for it to be correct...
Ideally, I would like to be able to do something similar to
<br />
...<br />
DialogResult response = MessageBox.Show(...);<br />
if (response == DialogResult.OK)<br />
...<br />
...but using a context menu (because I want to be able to select from a list of options and not just Yes or No but mainly so that users do not get upset if they were to see a Message Box rather than a context menu...).
Any ideas or help would be greatly appreciated!
cheers!

that's because contextMenuStrip.Show(); doesn't work like ShowDialog.. it only presents you the menu..
if "...doSomethingElse" depends on what user does/selects in the menu you should put it in context menu items event handlers.. onClick for MenuItems for example..

cheers! that makes sense. The code will need a little refactoring though...

Hi, i'm creating a C# program that measures date differences. for example i have 2 text boxes, one text box contains the date 4/12/2007, the other text box contains 5/23/2008. I need to count the number of days difference from 4/12/2007 to 5/23/2008.
Im sorta new to C# and i have no idea how to do this, since i cant just treat it as simple numerical values, given that it must reference the calendar for the measurements to be exact.
thanks in adavance..
