I want to take the value of textBox1.text, pass it to a find routine and then display the results of all lines that have the given text.
The find portion I have figured out. the IndexOf routine I have not figured out.
Here is my find routine;
private void btnFind_Click(object sender, System.EventArgs e)
{
try
{
int StartPosition;
StringComparison SearchType;
if (chkMatchCase.Checked == true)
{
SearchType = StringComparison.Ordinal;
}
else
{
SearchType = StringComparison.OrdinalIgnoreCase;
}
StartPosition = mMain.rtbDoc.Text.IndexOf(txtSearchTerm.Text, SearchType);
if (StartPosition == 0)
{
MessageBox.Show("String: " + txtSearchTerm.Text.ToString() + " not found", "No Matches", MessageBoxButtons.OK, MessageBoxIcon.Asterisk);
return;
}
mMain.rtbDoc.Select(StartPosition, txtSearchTerm.Text.Length);
mMain.rtbDoc.ScrollToCaret();
mMain.Focus();
btnFindNext.Enabled = true;
}
catch (Exception ex)
{
MessageBox.Show(ex.Message.ToString(), "Error");
}
}
Lets say I want to search for and display every line that has the word "one" in it and then display it in a RichTextBox
one plus four
two plus four
three plus four
one minus four
one divided by four
two minus four
two divided by four
three plus five
three minus five
When the search is done, it show like this in the RTB with nothing else.;
one plus four
one minus four
one divided by four
Thanks in advance!

Hello,
I'm not sure if I understand you right,
but if you have a multiline TextBox and want to iterate over the lines to find the lines with a search string in it.
Then use a method like this:
using System.Collections.Specialized;
public static StringCollection FindLinesOverSearchString(string[] LinesToSearch, string TextToSearch)
{
StringCollection resultLines = new StringCollection();
if(LinesToSearch!=null)
{
foreach(string actLine in LinesToSearch)
{
if(actLine.IndexOf(TextToSearch)!=-1)
{
resultLines.Add(actLine);
}
}
}
return resultLines;
}
And call it like this:
StringCollection textboxresult = FindLinesOverSearchString(yourTextBox.Lines, "searchstring");
All the best,
Martin

Martin, if I understand you correctly,
The method will find what I want.
I am not sure I understand how I take the value of the textbox as a string and pass it to the above routine and then get it to the second textbox.
I understand the string collextion piece, as it looks fairly simple in that respect.
Thanks,
Brian

You don't need to do that.
The method I posted, takes a string[] as parameter for the lines to search.
The TextBox class has a property called "Lines" which is type of string[], and this will be passed as parameter.
FindLinesOverSearchString(yourTextBox.Lines, "searchstring");
The second parameter is quit simple the string to search.
The result is in my case a dynamic collection of the type: System.Collections.Specialized.StringCollection.
This class has an "Add" method, which will be used to add the matching line to the collection.
If you now have the result and want to show it in a second multiline textbox:
StringCollection resultLines = FindLinesOverSearchString(yourTextBox.Lines, "searchstring");
string[] resultAsStringArray = new string[resultLines.Count];
resultLines.CopyTo(resultAsStringArray,0);
yourTextBoxResult.Lines = resultAsStringArray;
Hope it helps!
All the best,
Martin

That explains it better. I will have to mull this over a little more before I get it to sink in and work the way we are talking about.
Thanks for the help!

Here's how you can use IndexOf()
<br />
int hasOne;<br />
<br />
string strWorkString = string.Empty;<br />
strWorkString = "one plus 3";<br />
<br />
hasOne = strWorkString.IndexOf("one");<br />
That will report where in the string "one" is found. Also,

When you do that, you should really use string.Format(). Do it like so:
<br />
MessageBox.Show(string.Format("String: {0} not found", txtSearchTerm.Text.ToString()), "No Matches", MessageBoxButtons.OK, MessageBoxIcon.Asterisk);<br />

hi
my application is written in Compact framework 2003. it works for both on desktop and device but i need to show tooltips for the desktop version. the tooltip control is not present as it is CF.
any help please...
thanks.
|
|
|
|
|
does the controls have the tooltip in its properties ?
|
|
|
|
|
this is what i do if the application is in .NET Framework
private void button1_MouseHover(object sender, System.EventArgs e)
{
toolTip1.SetToolTip(button1,"Hello World");
}
toolTip1 is an object of the ToolTip control present in the toolbox. but i dont have this control in the toolbox for compact framework.

Hi,
the tooltip will show itself automatically, you don't need to bother about
the hover event. Just do toolTip1.SetToolTip(button1,"Hello World"); once,
maybe in your form's constructor or its Load event.

My boss wants me to add a function in the customer sign up that checks a database against wanted terrorists and their alias names they are using. Anyone know if there is a public database to query for names and photos.

Why don't you ask him to give you the list?

Ha you should only know how many diffrent banks and service companies that runs checks against goverment databases for people who is suspected of terrorist acts or involment and is wanted by FBI and Interpol. Its not a 10 people list. this is 1000 of peoples and aliases that is used out there both here in the states and in Europe.

the question is not abt the list of ppl or whats happening in Europe or Interpol. Question is.. where have u specified the tables. You're just telling us, hey u guys my boss needs a list of terrorist and that... how in the world are we supposed to know where its gonna come from.
