You can run your installation with /q as parameter to let windows installer work without showing dialogs. If you need the values of some variables in your installation, these can be added as arguments to your call to msiexec like this:
msiexec /i mypackage.msi /q VALUE1=ABC VALUE2=123

You can put this call into an executable as well (for example, using Process.Start to run windows installer).

Perhaps the Windows Installer command line options[^] will help as well.

Printing Rich Text Box to printer

Good Day,

I am printing a form to a printer, but when I type in text, to my Rich Text Box, I noticed that the printer prints the size of the box (616,64), but if there is any text that you need to scroll to see, it prints it below the box! It's really kind of funny....

How can I change my code (below) so that it prints all the text in the box, without going outside the box, I guess it needs to dynamically change the size of the Rich Text Box being sent to the image....

Any help would be great!

case "RichTextBox":

RichTextBox rtb = (RichTextBox)c;

g.FillRectangle(new SolidBrush(rtb.BackColor), rtb.Left+1, rtb.Top + 1, rtb.Width+2, rtb.Height -2);

g.DrawString(rtb.Text, rtb.Font, new SolidBrush(rtb.ForeColor), rtb.Left + 2, rtb.Top + rtb.Height/2 - g.MeasureString("a", rtb.Font).Height/2, new StringFormat());

break;

I am assuming I need to change the g.DrawString, but not sure to what.

Thanks,

G

That way you'll never get an accurate picture of your RichTextBox.
You're printing a string with a constant font, although the RichTextBox can contain many different fonts and the text inside the RTB (or a TextBox) can be a lot longer than what is visible in the control.

I'd suggest you search CP for "hardcopy" (there are some articles on the topic) and then use the actual image you grab for printing.

Thanks for the reply Mav, upon searching the site for 'hardcopy', all I found was one project that was similar, but it was mostly in French. I'll keep looking...

Thanks,

Ok, "hardcopy" wasn't the best of all search terms, "screen capture" should find you more and more appropriate results.

There's TWAIN support in C# ? Or are you using an external API ? If the latter, I'd be checking their docs to see what they return. If the former, please tell us where the built in TWAIN stuff is.

Use the WaitForExit method. Like this

void RunProcesses(string[] executableNames)
{
   foreach(string executableName in executableNames)
   {
       System.Diagnostics.Process.Start(executableName).WaitForExit();
   } 
}

Wait for the Process to finish, then start the next one.

Or indeed try: System.IO.Path.GetDirectoryName(string path);

For your example calling System.IO.Path.GetDirectoryName("c:\\gello\\txt.xtx"); will return the string "c:\\gello".

Good evening,
I have a problem in retrieving active ip addresses(with computer name) in a network, using C#. I could able to retrieve through dns entry, but it has to retrieve only if the computer is active. But my code retrieves even if the computer is off.
can someone help in this view?

Amar

DNS doesn't work that way, AFAIK. There are designated name servers which your computer will use to resolve IP addresses, so you'll get the addresses regardless of whether the PC with that IP address is alive.

You can always try connecting to the IP address (say ping) to see if the other side is really alive.

Regards
Senthil

Senthil is right. DNS resolves address and names regardless of the hosts actual status. You can resolve addresses and names for machines that don't even exist, so long as there is an entry in the DNS tables.

If you want to resolve a host name, you'll have to do the DNS lookup first to get the address(es) of the host, then ping that address to see if it is alive. For an address, you'll just ping the address first to see if it's alive, then if it is, do the DNS lookup for the host names.

But, keep in mind, that not all machines will respond to a ping, even if it alive and reachable.

Open Google.

Search for "Gina DLL".

Click the MSDN-Entry.

Sorry, no more help to offer, I just looked this up myself. I just wanted to make sure we were not talking about desktop dancers/strippers.

Cheers,
Sebastian

I'm trying to capture text from a rich edit textbox. I have a section of code I took from the PInvoke website. it correctly determines the length of the text to be captured, however it doesn't actually capture any text. I'm using this code:

<br />
private static String GetWindowText(IntPtr hWnd)<br />
   {<br />
	IntPtr txtLength;<br />
	IntPtr retValue;<br />
	IntPtr zeroVal = new IntPtr(0); <br />
	//Get the length of the text<br />
	uint WM_GETTEXTLENGTH = 14;<br />
	txtLength = SendMessage(hWnd, WM_GETTEXTLENGTH, zeroVal, zeroVal);<br />
        //textBox2.Text = txtLength.ToString();<br />
<br />
        //Setup the size of the sb<br />
	StringBuilder sb = new StringBuilder(txtLength.ToInt32() + 1);<br />
<br />
	//Get the text of the window/control t<br />
	uint WM_GETTEXT = 13;<br />
	retValue =  SendMessage(hWnd,WM_GETTEXT,txtLength,sb);<br />
<br />
	//Return a string<br />
	return sb.ToString(); <br />
}<br />

The retValue variable equals zero after it is updated and sb contains no characters. Any help would be greatly appreciated.
