Re: Way to retain focus of transparent form application.

I do not want the window to loose focus at all, because user will be drawing on this transparent window.
Isn't there a straightforward way to do it, than to hack/tweak things?

Did you try setting the topmost property to true?

Yes, I tried that. It is not effective.

How about skipping all this garbage and taking a screen shot and drawing on that instead. No need to worry about transparency and mouse clicks going to the wrong form at all.

Yes, that's an option I am considering right now.
But if I could make it draw directly on screen it would have been much more better.

Thanks,

I got this from MSDN before

[DllImport("user32.dll")]
private extern static IntPtr SetActiveWindow(IntPtr handle);
private const int WM_ACTIVATE = 6;
private const int WA_INACTIVE = 0;


protected override void WndProc(ref Message m)
{
    if (m.Msg == WM_ACTIVATE)
    {
        if (((int)m.WParam & 0xFFFF) != WA_INACTIVE)
        {
            if (m.LParam != IntPtr.Zero)
            {
                SetActiveWindow(m.LParam);
            }
            else
            {
                SetActiveWindow(IntPtr.Zero);
            }
        }
    }

    base.WndProc(ref m);
}

ConfigurationManager - how to read/write into a custom section?

19-Jun-09 12:24

This does not work. I tried this one as well as the

  [DllImport("user32", CharSet = CharSet.Auto)]<br />
        private extern static int SendMessage(<br />
           IntPtr handle, int msg, int wParam, IntPtr lParam);<br />
<br />
        [DllImport("user32", CharSet = CharSet.Auto)]<br />
        private extern static int PostMessage(<br />
            IntPtr handle, int msg, int wParam, IntPtr lParam);<br />
<br />
        private const int WM_ACTIVATE = 0x006;<br />
        private const int WM_ACTIVATEAPP = 0x01C;<br />
        private const int WM_NCACTIVATE = 0x086;<br />
<br />
<br />
        /// <summary><br />
        /// Subclasses the owning form's existing Window Procedure to enables the <br />
        /// title bar to remain active when a popup is show, and to detect if<br />
        /// the user clicks onto another application whilst the popup is visible.<br />
        /// </summary><br />
        /// <param name="m">Window Procedure Message</param><br />
        protected override void WndProc(ref Message m)<br />
        {<br />
            <br />
                // check for WM_ACTIVATEAPP and WM_NCACTIVATE<br />
                if (m.Msg == WM_NCACTIVATE)<br />
                {<br />
                    <br />
                    // Check if the title bar will made inactive:<br />
                    if (((int)m.WParam) == 0)<br />
                    {<br />
                        xyz += m.Msg + " ";<br />
                        // If so reactivate it.<br />
                        SendMessage(this.Handle, WM_NCACTIVATE, 1, IntPtr.Zero);<br />
<br />
                        // Note it's no good to try and consume this message;<br />
                        // if you try to do that you'll end up with windows<br />
                        // that don't respond.<br />
                    }<br />
<br />
                }<br />
                else if (m.Msg == WM_ACTIVATEAPP)<br />
                {<br />
                   <br />
                    // Check if the application is being deactivated.<br />
                    if ((int)m.WParam == 0)<br />
                    {<br />
                        xyz += m.Msg + " ";<br />
                        // And put the title bar into the inactive state:<br />
                        PostMessage(this.Handle, WM_NCACTIVATE, 0, IntPtr.Zero);<br />
                    }<br />
                }<br />
                <br />
                base.WndProc(ref m);<br />
        }

code.

Later code actually does the reverse of what I want, but still it does not work.

Neither works.

My config file:

<?xml version="1.0" encoding="utf-8"?>
<configuration>

  <appSettings>
    <add key="sunshine" value="125" />
    <add key="moonshine" value="50" />
    <add key="seashine" value="10" />
  </appSettings>
  
  <Settings2>
    <add key="persistent" value="0" />
    <add key="smooth" value="1" />
  </Settings2>
  
</configuration>

I can read/write settings into <appSettings> but don´t know how can i read/write from <Settings2> .... and if i can create new sections like <SettingsN>
...
I´m using System.Configuration but only could read/write into the default section named <appSettings>... perhaps someone can give me a hand or point me to the right direction, thanks in advance.

System.Configuration only exposes methods which for the predefined section (i.e. appsettings).

For your purpose, you should rather consider it as a normal xml file and do the read/write.

As modifying configuration files directly can be very dangerous. You should also take a look at How to: Create Custom Configuration Sections[^].

There are also loads of articles, which you might find easier to understand. Just Google for Custom Configuration Section

Replace Function

Vimalsoft(Pty) Ltd19-Jun-09 7:01

Good Evening All

Am amazed that i cant use the Replace Function , its Probably the long that i had.

i have the Following code

String Username = "Vuyiswa";

          String Password = "secret";

          String strBody = @"<p>Thank you for using !obooking System <br><br> Username:(Username)<br><br>Password:(Password)<br<br>Kind Regards !oBooking</p>";

          strBody  = Regex.Replace(strBody,Username,"(Username)");

          strBody = Regex.Replace(strBody, Password, "(Password)");

          Response.Write(strBody);

i have tried the Normal replace Function, but the Variables are not returned with the Variables values.

Thanks

string username = "user1";
string password = "pass1";

string body = "something with a (username) and a (password)";

body = body.Replace("(username)", username);
body = body.Replace("(password)", password);

you saying that does not work?

you can also do...

string body = "something with a " + username + " and a " + password;

or...

string body = string.Format("something with a {0} and a {1}", username, password);

...I think your regex could have something to do with the brackets which are used in regular expression to specify a group, but I'm not sure about that

i used it this way

string Username = "Vuyiswa";

          string Password = "secret";

          string strBody = @"<p>Thank you for using !obooking System <br><br> Username:(Username)<br><br>Password:(Password)<br<br>Kind Regards !oBooking</p>";
      strBody = strBody.Replace("(Username)", Username).Replace("(Password)", Password);

          Response.Write(strBody)

but what is the Difference between this

strBody.Replace("(Username)",Username);

strBody.Replace("(Password)",Password);

and this working code

strBody = strBody.Replace("(Username)", Username).Replace("(Password)", Password);

Thanks

Hi,

string.Replace creates and returns a new string, so do strBody.Replace(...);
that also is why the second way does work.

Hi,

nothing gets replaced, since there is no match: "Vuyiswa" and "secret" are not present in the original strBody.

That means the Replace Function intellisense is misleading because it says

strBody.Replace(char oldchar,char newChar)

musefan19-Jun-09 7:38

musefan

19-Jun-09 7:38

that is just one of the functions signatures, the other is with string types instead of char types

your intellisense should show multiple signatures available that you can cycle through with the Up/Down arrow keys

that is completely irrelevant, your original post and my reply to it referred to Regex.Replace, not string.Replace; and there are no char variables present at all.
