How to trigger Paste in terminal server window? - C# Discussion Boards

Take your pick from the following (result == "0010" in all cases)...

int j = 10;
string result;
result = j.ToString().PadLeft(4, '0');
result = j.ToString("D4");
result = j.ToString("0000");
result = string.Format("{0:D4}", j);
result = string.Format("{0:0000}", j);

Sounds like somebody's got a case of the Mondays

Display limited items in listbox using C# from xml

What, you don't think he intended to have "0-99" as one of his integer strings? Yes, but in an if statement, (0-99) == -99, so I think this is exactly what he was looking for! Poke tongue | ;-P

Hi,
I have a xml file.I am trying to display the specific contends in a list box. for example::this is my xml contend.In the below items i want my list box to display only whatever is in "connection name".

connectionname>Anet
subnetmask>x.x.x.x
defaultgateway>x.x.x.x
dns1>x.x.x.x
dns2>x.x.x.x
dns3>x.x.x.x
dns4>

<con>
connectionname>BL
subnetmask>x.x.x.x
defaultgateway>x.x.x.x
dns1>x.x.x.x
dns2>x.x.x.x
dns3>x.x.x.x
dns4>
/con>

My code is displaying the full contend.
XmlTextReader textreadobj = new XmlTextReader(@"C:\Documents and Settings\j\My Documents\Visual Studio 2005\Projects\InternetApp\InternetApp\XMLFile1.xml");

textreadobj.Read();
while (textreadobj.Read())
{

lstProvider.Items.Add(textreadobj.ReadString());

}

So how can i make it display the items in connection name only.
Thanks in advance

Regex.....Problem...........

string sPattern = @"[^\p{Cc}\\r\\n\\a\\e\\b\\t][\S]*[\w\p{Po}\s-`\p{Sm}]*[^\p{Cc}\\r\\n\\a\\e\\b\\t]";

try
{
if (Regex.IsMatch(txtText.Text, sPattern, RegexOptions.Multiline | RegexOptions.IgnoreCase))
{

objMatch = Regex.Match(txtText.Text, sPattern, RegexOptions.ECMAScript | RegexOptions.Compiled
| RegexOptions.Multiline | RegexOptions.IgnoreCase);

if (objMatch.Success)
lblDone.Text = objMatch.Value;

}//end (if (Regex.IsMatch...)

}//end(try)

finally
{
sPattern = null;
}//end (finally)

input string is :-- \r\nloadplayer "playername=test_1"\r\n

output string should be :-- loadplayer "playername=test_1"

want to neglect all newline,tabs.. etc from the input string.

Now its doing fine, but also removing "r,n,a,e,b,t" from the starting of the input string.

Means, if the input string is:-- roadplayer "playername=test_1"\r\n
output becomes:-- oadplayer "playername=test_1"
it should be:-- roadplayer "playername=test_1"

so, tell me what i should do for better working.

Thxx...

Enjoy!!

The 'escape characters' are all in the format '\x'.
\n is new line... etc.

'\\' in a string represents a '\', a single '\' will look like an escape character.
So you need to use: \n \r etc instead of \\n \\r.

I've never use Regex before but I assume this is right.

Hope it helps.

How to trigger Paste in terminal server window?

Re: How to trigger Paste in terminal server window?

14-Dec-07 2:58

Hi!
I've asked a similar question some time ago, but unfortunately without usable results, so I try again.

I put some text into the clipboard and want to trigger a paste action inside a terminal server session (i.e. programmatically do what happens when you press Ctrl+V inside a mstsc window).
Yes, I know that you can't programmatically see the different windows inside the WTS session and that the currently active application will be the target for my paste, but that's exactly what I want.

So far I tried using SendKeys, P/invoke to SendInput and keybd_event, posting WM_PASTE or even WM_KEYDOWN and WM_KEYUP with the exact parameters Spy++ reports, but I can't get it to work.
The first 4 ways simply give no visible result at all, with WM_KEYDOWN/UP I get a plain "v" instead of Ctrl+V.

Does anyone have any further idea?

Regards,
mav

Like this?

SendKeys.SendWait("[Clipboard content here]");

or like this:

// simulates a Ctrl+V keypress
SendKeys.SendWait("^a^v");

If you've tried the second one, it wont work - as you probably have noticed. Console windows doesn't accept pasting of text. Try getting the content of the clipboard somehow, store it in a string and then write it out like this:

SendKeys.SendWait(clipboardContent);

Hi!
First of all, thanks for you reply.
Unfortunately, neither the first nor the second version has any visible effect on the mstsc window.

Why not do the following, where you know how to write a single char to the console (as indicated in your question where you said you can send a 'v' character):

if (Clipboard.ContainsText()) {
    string ct = Clipboard.GetText();
    foreach (char c in ct)
        WriteCharToConsole(c);
}

I know it is a hack, but it will work. Sorry for not getting back to you on your original post, but I got kind of sidetracked. I still plan to look into how to do this the "right" way, but this will suffice until then.

No problem here - you're not obliged to solve my problems Smile | :)

The main reason why this "hack" won't do, I'm afraid, is that the clipboard contains RTF...

Nevertheless, thanks for the suggestion.

What if you read the RTF into the RichTextBox.Rtf property, then read it back out from the RichTextBox.Text property? This raises the hack level to about a 9 out of 10, but again, I think it may work for you. Also, isn't there a way to get RTF text from the clipboard without the formatting? You may want to check into that as well.

Re: How to trigger Paste in terminal server window?

14-Dec-07 20:25

Sure, there are easy ways to retrieve plain text from RTF, but that's not the point.
The requirement is to paste the contents of a RichTextBox into the terminal server session, just like one would with a local application. Formatting etc. has to be retained.

What I cannot understand is that I don't get the same results when sending the same messages with the same parameters Spy++ is recording...

Windows Forms DataGrid View Clearing Problem

15-Dec-07 6:40

Victory is mine! (as Stewie Griffin would say)

Finally, I got some code from a guy in an MCE forum who was sending keystrokes to an mstsc window in response to IR remote control events.
He also used keybd_event (which didn't work in my tests), but also used AttachThreadInput, so I think this was the missing piece.
With this code I was able to send Ctrl+V to mstsc, thus triggering paste into the current application. Works like a charm!

Anyway, thanks for your support!

mav

Hi,
I am using a DataGrid View on my windows forms.
I want to clear all the rows of the grid on certain event, for that i tried to set the data source property to null. But it also cleared the columns.
I also tried to use the clear function of the rows ut it was of no help;
How can i just clear teh rows and let the columns be intact in there.

Thanks.

Clearing a row would surely clear columns too?

Can you give an example of what the result you are looking for?

deepaks314-Dec-07 1:35

14-Dec-07 1:35

Ok,
There are cerain no of rows in the grid, so when i click on the clear button i want that only the column names should be visible but not any rows.

And i have aded the columns on the design time, so i want to retain those columns.

Isn't there a Rows collection that you can clear? AFAIK, it shouldn't change the column headers...

You may clear the value in loop using row index and column index;
for example: setting null to Row index 0, Column index 0
dgvItemList.Rows[0].Cells[0].Value = "";

I think, u got it. Best of Luck.

Instead of trying to clear the rows on the dataGridView, try clearing the rows on it's data source. lets sat the source of the datagridView is in a DataSet. Lets just make this one up: this.YourDataSet.YourDataTable. Clear the rows from the DataTable, and the DataGridView will see the changes in the DataTable and reflect the cleared rows. Try this:
this.YourDataSet.YourDataTable.Clear();
