I am facing a situation where i need to change the border of a rich textbox ontrol from shrp corner to rounded rectangle. Can anyone help me to solve this problem in a easier way using C#.net 2005.
Is it needed to use GDI and painting to change the border to rounded rectangle.
Any replies will be great. thanks in advance.

I strongly doubt you can do this by modifying a RTB.
You could create a rounded rectangle Panel and place a regular RTB with BorderStyle=None on this Panel.

I will try it and inform you.

Hi,

At the time of closing the application, it gives System.NullReferenceException. I had tried by calling destructor and base class dispose method but this exception is still coming.How can I resolve this exception?
Thanks In Advance

Do you know which line of code and even more interesting which object causes this exception? If not, try to find out and afterwards explore where this object is previously set to null or why it wasn't initialized.

Hi,
I had a default role for a new member in my web.config file. Something with a value like "Member", but now I changed it to the corresponding ID (auto incrementing value):
<add key="DefaultRoleForNewMember" value="2"/>
I have a public method that goes and retrieves this value. When the value was still a string and not the 2, my function worked like this:
public static int DefaultRoleForNewMember
{
get
{
string strRole = WebConfigurationManager.AppSettings["DefaultRoleForNewMember"]);
if (string.IsNullOrEmpty(strRole))
throw (new NullReferenceException("DefaultRoleForNewUser configuration is missing from your web.config. It must contain <appSettings> <add key=\"DefaultRoleForNewUser\" value=\"Member\" /> </appSettings>"));
else
return (strRole);
}
}
Now that I have the value of 2, I will have to convert it to an int when getting the value for the web.config file. But now my confusion comes in where I throw an exception, like I had for if (string.IsNullOrEmpty(strRole))
I hope this is clear enough. Please let me know.
Regards,
ma se

I would do the conversion to an integer inside the else branch. If the conversion goes wrong you could throw another exception there telling that the DefaultRoleForNewUser exists but is invalid.

What exception must I try and catch?

Look at the error message, it will tell you exactly what class it has problems with. Then you look up the class in MSDN Library[^], there you will see what namespace the class is in.

Hi,
I hope I'm not the only one hit by this: in some window forms I have a DataGridView having a DataSet (filled from a select) and AutoSizeColumnMode set to Fill. Before the form is showing up I get an unhandled exeption message with "This operation cannot be performed while an auto-filled column is being resized" - I have no clue about what operation we talking about and the exception is thrown randomly (and never if step through the application in debugger). If click Continue everything is OK, the form comes up filled, aligned and resized.
Somebody please give me a hint.

Hi,
I have a Win Form with a Main Menu, and I need to open one of these menu options via code.
I'm trying to password protect a menu. I've got it set up so that when a user selects a particular menu option, a Form pops up asking for a password. The trick is to open the menu without a select event happening (after the password is verified).
If you know of a better way to go about this, that would be great. I could have all the SubmenuItems Enabled=false by default and then change to true, but I think it would be better not to show the SubmenuItems at all.
Thanks,
Ron

Hi!
Simply set the Visible property of the menu items in question to false and change it to true once the password has been verified...

Thanks Mav,
I put the menu as not enabled. I didn't think that you could have a click event on an unenabled menu... but you can. When the password is verified, the menu becomes enabled.

Do you mean scanning a the resume on a paper using a scanner? 
If yes then you could always scan a document and store it in word format, then use the Word API to read the contents of the file and store them in your native format.
Hope this helps.

hi all,
I need to split below string using another string "
"
MINIMUM STAY:
NILL
MAXIMUM STAY:
1M
DATE/ROUTE CHANGES:
REBOOKING
Before departure - Charge GBP30
After departure - Charge GBP30
when I am doing like this
string[] lparr=lstrFileContent.Split("
".ToCharArray());
when I am doing like this, string spliting it using char '<','H','R','>'.
But I need to split using whole "
".
So can any one please tell me how to split a string using another string?
thanks in advance.....

public String[] ConvertString(string Str)
{string [] StrArray = Str.Split(new Char [ ] {'H'});
return StrArray;
}
the only thing is, this splits a string into an array,
you could then pluck out each of the values out of the array
|
|
|
|
|
If you are using the .net 2.0 framework you can use the following call:
string[] lines = "Line1<HR>Line2".Split(new string[] { "<HR>" }, StringSplitOptions.RemoveEmptyEntries);
|
|
|
|
|
You could replace the string "<HR>" with a single character that's not used elsewhere (even '\0' works, btw.) and then use a regular string.Split with the substitute character:
string tmp = lstrFileContent.Replace("<HR>", "\0");
string[] lparr = tmp.Split('\0');

Nice, I like this idea, should come in handy when working on .net 1.1
static string[] Split(string stringToSplit, string seperator)
{
char sep = '\0';
while (stringToSplit.IndexOf(sep) >= 0)
{
sep++;
}
stringToSplit = stringToSplit.Replace(seperator, sep.ToString());
return stringToSplit.Split(sep);
}
Usage:
string test = "Split this<HR>here";
string test2 = "Split here<HR> but ignore\0 null<HR>\x01 yea";
string[] lines = Split(test, "<HR>");
string[] lines2 = Split(test2, "<HR>");
