Re: String Escapes - C# Discussion Boards

I need to embved a quote(") into a string i tried \" but that doesn't remove the \ on runtime. I am trying to make a reuseable RegEx statement.

Regex rxFind = new Regex(szQuery);

When I run the code, szQuery contains the \" instead of just the ".

How do I fix this, or what is the better way to do this?

Embedding a quote into a string with \" does remove the \ on runtime, unless you are accepting input from the user, in which case, you do not need to escape the quote.

If you are trying to make a reusable Regex statement, you will always want to do:
Regex rxFind = new Regex(Regex.Escape(szQuery));
This makes sure that all characters that are part of the syntax of reguar expressions are translated so that they do not effect the expression.

Seperately, you could add more slashes (\\\" instead of \"), because they are significant in Regexes.

ToolTips for custom tabs

Is it possible to attach ToolTips for individual tabs of a TabControl?
I've tried setting ToolTips to TabPage and TabControl, but both attemps failed.

This works in Mozilla browser for both selected and unselected tabs.

The only solution I thinked up was to catch MouseMove events of a TabControl and look which tab is currently under mouse cursor. There's still a problem of how to show ToolTip (or something similar) statically. But I believe there's some cleaner and easier way.

You have to set the 'ShowToolTips' Property of the Tabcontrol to true before the Tooltips of the tabpages are shown.

This doesn't work:

<br />
      tabControl1.ShowToolTips = true;<br />
      <br />
      ToolTip tt = new ToolTip();<br />
<br />
      tt.ShowAlways = true;<br />
<br />
      tt.SetToolTip(tabControl1.TabPages[0], "1");<br />
      tt.SetToolTip(tabControl1.TabPages[1], "2");<br />
<br />
      tt.SetToolTip(tabControl1, "tabcontrol");<br />

ToolTip is shown on the tabs, but its the "tabcontrol" ToolTip. The "1" and "2" will show only when user moves cursor on the surface of the selected tab Frown | :(

Still thanks.

No you have to set the Tooltip directly:

tabpage1.ToolTiptext = "1";
tabpage2.ToolTiptext = "2";
tabcontrol1.ShowTooltips = true;

Then it should work.

Can anyone tell me why this isn't animating the window? It was doing it earlier but then it stopped for some reason Confused | :confused:

[DllImport("user32.dll")]<br />
static extern bool AnimateWindow(IntPtr hwnd, uint dwTime, uint dwFlags);<br />
<br />
enum AnimateWindowFlags : uint<br />

    Main_Form main = new Main_Form();<br />
            <br />
    AnimateWindow(main.Handle, 250, (uint)AnimateWindowFlags.AW_VER_NEGATIVE |<br />

Any help is appreciated. Laugh | :laugh:

Try calling AnimateWindow from the constructor of Main_Form

[DllImport("user32.dll")]
static extern bool AnimateWindow(IntPtr hwnd, uint dwTime, uint dwFlags);

enum AnimateWindowFlags : uint
{
    AW_HOR_POSITIVE = 0x00000001,
    AW_HOR_NEGATIVE = 0x00000002,
    AW_VER_POSITIVE = 0x00000004,
    AW_VER_NEGATIVE = 0x00000008,
    AW_CENTER = 0x00000010,
    AW_HIDE = 0x00010000,
    AW_ACTIVATE = 0x00020000,
    AW_SLIDE = 0x00040000,
    AW_BLEND = 0x00080000
}

public Main_Form ()
{
    ...
     AnimateWindow(this.Handle, 250, (uint)AnimateWindowFlags.AW_VER_NEGATIVE | (uint)AnimateWindowFlags.AW_CENTER);
    ...
}

That works, but only if I put it before InitializeComponent();
Which makes it animate but the form doesn’t start in the proper position because InitializeComponent(); hasn't been called yet Frown | :(

It's not that big of a deal anyway. Just weird that it would work and then decide not to Confused | :confused:

Probably something I did Laugh | :laugh:

Thanks anyway,

That is weird.

For me, it works both before and after InitializeComponent();
To get around it not starting in the proper position (at least in .net 2.0) you can do something like this:

public Form1()
{
    this.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen;
    /*
    //If you're setting the position manually:
    this.Top = 200;
    this.Left = 200;
    this.StartPosition = FormStartPosition.Manual;*/
    AnimateWindow(this.Handle, 250, (uint)AnimateWindowFlags.AW_VER_NEGATIVE | (uint)AnimateWindowFlags.AW_CENTER);
    InitializeComponent();
}

RegEx

Expert Coming7-Feb-06 12:21

7-Feb-06 12:21

I am using RegEx to find a section of a html document. The document can change, but the format is always the same.

I need RegEx to pull out:

>Name:VisualStudio

Then pull out VisualStudio (VisualStudio is a part of the page that may change)

Is there a way I can do this by passing strings to a function?

Thanks for any, and all help!

Help - Code

Expert Coming7-Feb-06 14:21

private static void InterpretData(string szProfile)
{
Regex rxFind = new Regex(@">Name Frown | :(

<szcharname>)");

MatchCollection matches = rxFind.Matches(szProfile);

foreach (Match match in matches)
{
if (match.Length != 0)
{
Console.WriteLine("Character Name: {0}", match.Groups["szcharname"]);
}
}

Console.WriteLine("RegEx'ed'");

Console.ReadLine();
}

It isn't finding a match. See anything?

I think that matches assumes you know exaclty the formet of the string. How do I FIND the string, then match it? Is there a better way?

You have specified that you want to find a question mark. That will match exactly one occurance of that character, nothing else.

Use a period to match any character (except line break), use a plus sign to specify that it should occur one or more times, and add a question mark after the plus sign to specify that it should match as few times as possible.

Regex rxFind = new Regex(@">Name:</td><td>(.+?)</td>");
