I am trying to load an rtf file which is created by using Wordpad into a richtextbox. However, the text seems lost some of its format information, e.g. text set to bold and different sizes, after been loaded into the richtextbox. How can I add these texts while retaining their format properties?

The RTB control doesn't support all of the formatting that Wordpad or Word saves into their RTF files.

OK, I have 2 questions about this function:
1. Why does this function stop working? On one machine (WinXP), this happened already, it won't beep. On another computer (WinXP also), it beeped fine until today that I loaded my project and tried it... I put that same project on another computer (Win2k) and it worked fine, so I grabbed its Kernel32.dll, renamed it, and then put it on the second PC I listed, but the program crashes, it returns to VS.NET without any exception message and then it puts the cursot on the "public static extern bool Beep();" line... How can I fix this? I really need this function! 
2. I used to code in a Windows scripting language that did all the datatype conversion stuff for you (http://www.autoitscript.com), and when I called the Beep function with decimal parameters, it worked, but when I try floats, doubles, and decimals in C# it doesn't beep!
If anyone can help, I'd be thankful for life! Thanks!

Is the PC speaker enabled? (Bios and Control panel) Does it work?
(Sometimes it really is a hardware problem  )
BTW, copying Kernel32.dll from one OS to another really is a bad idea...

I agree with Ron. Either you've got a hardware problem, or someone turned the volumn down on the speakers or in the Sound control panel or the little Volume slider, or muted either.
And yeah, copying Kernel32.dll from another machine is a REALLY bad idea. If you replaced with one in System32, it's amazing your machine even booted!
BTW: Beep takes two parameters: unsigned integers, NOT floats, doubles, decimals, ... floating point numbers will not work. The proper DllImport should look like this:
static extern bool Beep(uint dwFreq, uint dwDuration);

OK, what's the option in Control Panel, and what's the BIOS option usually called? I can't find 'em!
Thanks!

On XP:
MyComputer->manage->device manager
select the view menu and check (select) "show hidden devices"
expand the "non-plug and paly devices" node of the tree.
find "beep" and open its properties window. ensure it is enabled. (I hate the thing, mine is disabled)
Different BIOS will have differen places (or sometimes none at all) for this.
also, sttings->control panel -> sounds and audio devices: sounds tab - make sure the sounds scheme is not 'no sounds'. Make sure some sound is associated with 'default beep' On the volume tab, make sure 'mute' is not checked..

Uhh... "Show hidden devices"? Under View? Hmm... I don't have that! :S I have XP Home with SP2... Is there an alternative? Thanks!

Ahmed, perhaps a link to your article would be helpful, along with a description of your article.
Also, the C# forum is not the best location to post this.

You call that updated? You still aren't explaining anything your code is doing or why. It's still just a bunch of barely related code snippets, nothing more.

Guys, Gals
I can't find any info on how to search a treeView, basically I'm dreaming big and would like to find a way that as a user types in the textbox the search method scrolls thru the treeView to find the matching string of text... ie like you see in a windows help search.
any ideas,
|
|
|
|
|
Use a recursive function or a while loop to search through all the nodes in a treeview. When you find a matching TreeNode, call EnsureVisible() or some other function to make the treeview scroll down to it.
FindMatchingNode("http://judahgabriel.blogspot.com", this.treeView1.Nodes);
void FindMatchingNode(string text, TreeNodeCollection nodes)
{
foreach(TreeNode node in nodes)
{
if(node.Text.IndexOf(text) != -1)
{
node.EnsureVisible();
break;
}
else FindMatchingNode(text, node.Nodes);
}
}

Cool, Much thanks
but....
i can't seem to get it to highlight the node once it finds it....
???
|
|
|
|
|
Try setting the SelectedNode to the node you want selected. Also note that if you have HideSelection set to true that it won't show the selection if the tree doesn't have focus.

Can Some help me to make a textbox in which user can type only numerical or Uppercase charecters ?
|
|
|
|
|
|
Itis bretty easy just override the OnTextChanged event and check the new char if it is a number or uppercase,you can know about numbers by putting them in an array,or just trying double.TryParse() function,in a try-catch block;
|
|
|
|
|
Capture the KeyPress Event of TextBox
The following is for numeric. Add condition for Upper Case.
private void TextBoxInceptionANAKeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
try
{
//Handle only if the value being entered is NUMERIC
if (e.KeyChar >= (char) 48 && e.KeyChar <= (char) 57 )
{
e.Handled = false;
}
else
{
//Sound beep
MutualFundHelper.SoundBeep();
e.Handled = true;
}
}
catch (Exception exception)
{
MessageBox.Show(exception.Message);
}
}

Hello,
I have dynamically allocated menu items, and for eahc of these menus I have submenus.
foreach (object i in versionsAnddates) {
string[] splitStr = Convert.ToString(i).Split('~');
SubMenu = new MenuItem ();
SubMenu.Text = "Version: "+splitStr[0]+" --- "+splitStr[1];
this.projectsMenu.MenuItems.AddRange (new MenuItem[] {this.SubMenu});
this.projectsSubMenu.Click += new System.EventHandler(this.Version_Click);
}
How can I pass some of the parameters (some string for example) to the Version_Click event when menu item is clicked?
Thank you
