here is my problem.
i have a RichTexBox with a document in it. after some modifications it needs to be printed. however in the printed version no white spaces must be left from the end of a paragraph to the end of the line.
i have tried to adjust the size of the RichTextBox to the size of the paper used by the printer (usualy A4) and set left and right indentation of text (making a copy of the rtf before this in order to print it unindented, otherwise it will just double the indentation) accordingly to printer settings indentation values.
however print preview and printed version text differs from the one shown on screen. the text is printed as formated text with justified align and different fonts and sizes, using a control derived from RichTextBox witch has such printing support described here
now if anyone has any ideas as to how i can atleast hadle this problem ..

hi,
i found something rather odd and was simply wondering if anyone can explain this. I have a thread responsible for displaying a Form (in an event driven manner). When trying to display this form, i've notived that usage of .Show() causes the new form to hang (the frame is displayed, but the text field in it is empty, and the mouse shows an hourglass when hovered over this form). On the other hand, use of .ShowDialog() seems to display it fine. Given that it's displayed in its own thread, it doesn't matter which method i use, as the application continues fine. But i was just wondering if anyone can explain why the behaviour is different in this context?
In case it's of any relevance, here's the code
(running on XP Pro, developed in VS .Net 2003 against SDK 1.1)
<code>
public PopupFactory()
{
Thread t = new Thread(new ThreadStart(waitForEvents));
t.start();
}
private void waitForEvents()
{
while ( true )
{
lock(al)
{
Monitor.Wait(al);
l.log("got a pulse from another thread on al");
string[] z_details = (string[])al[al.Count - 1];
ZTransparentWindow z = new ZTransparentWindow(z_details[0], z_details[1]);
z.ShowDialog();
z.Show();
}
}
}
</code>
thanks!

The reason Show doesn't work is because your thread doesn't have a message pump. Without a message pump, your window can't respond to user actions. ShowDialog runs its own message pump on the calling thread, so it works. See this[^] article to know more about message pumps and stuff.

I too have come across this seemingly odd error, however the solution is pretty clear once you figure out what's happening. An example solution would be as follows:
private delegate void ShowFormDelegate(string[] details);
...
public PopupFactory()
{
Thread t = new Thread(new ThreadStart(waitForEvents));
t.start();
}
private void waitForEvents()
{
while ( true )
{
lock(al)
{
Monitor.Wait(al);
l.log("got a pulse from another thread on al");
string[] z_details = (string[])al[al.Count - 1];
this.ShowForm(z_details);
}
}
}
public void ShowForm(string[] z_details) {
if(this.InvokeRequired)
{
this.BeginInvoke(new ShowFormDelegate(ShowForm), new object[] z_details});
}
else
{
ZTransparentWindow z = new ZTransparentWindow(z_details[0], z_details[1]);
z.Show();
}
}
Although I haven't tested the code, and therefore cannot guarantee that it works, you should be able to get the idea behind it. I myself am still not QUITE certain why the Show() method doesn't work the way you had it, but I assume it has something to do with the thread that it's being called from. This method guarantees that the form is spawned from the main window. Good luck.

In richtextbox has Undo(), but it clear all text
I want it excute such as notepad program
hello
|
|
|
|
|
The Undo function in a RichTextBox behaves like the one in a TextBox (what Notepad is, basically).
If you want anything else you'll have to specify it more clearly.

Dear everybody
I am programming with DataGrid control in C#. The problem is that when my column header text is too long. How can I make this text wrapped into another line? The same problem with the column header but in the case I want the text showed vertically.
Thank you very much

|
try it by increasing header font size.
|
|
|
|
|
Font's size doesn't affect anything. When the text is too long, it is just hidden by other columns. And if you want to show the text vertically, you have no way???
|
|
|
|
|
for increasing the column header we can use this code
but i could not find to wrap it.
DataGridTableStyle dgTbStyle = new DataGridTableStyle();
dgTbStyle.MappingName = tb.ToString();
dataGrid1.TableStyles.Add(dgTbStyle);
dataGrid1.TableStyles[0].GridColumnStyles[0].Width = 100;
dataGrid1.TableStyles[0].GridColumnStyles[1].Width = 150;

Thank you for you timely help. It's easy to change the width of the column's header. But there is no place in DataGrid that support us to change the height. It seems that DataGridView in .Net 2005 has this features. However, I want this for my application. Can you give me the answer?

The code is as follows:
this.client = new RTCClientClass();
this.client.Initialize();
this.client.EventFilter =RTCConst.RTCEF_ALL;
this.client.IRTCEventNotification_Event_Event += new IRTCEventNotification_EventEventHandler(OnRTCEvent);
void OnRTCEvent(RTC_EVENT rtcEventType, object rtcEvent)
{
Trace.WriteLine("Entering RTCPresenceCore.OnRTCEvent " + rtcEventType);
switch (rtcEventType)
{
case RTC_EVENT.RTCE_REGISTRATION_STATE_CHANGE:
this.OnRTCRegistrationStateChangeEvent((IRTCRegistrationStateChangeEvent) rtcEvent);
break;
case RTC_EVENT.RTCE_CLIENT:
this.OnRTCClientEvent((IRTCClientEvent)rtcEvent);
break;
case RTC_EVENT.RTCE_BUDDY:
this.OnRTCBuddyEvent((IRTCBuddyEvent2)rtcEvent);
break;
case RTC_EVENT.RTCE_ROAMING:
break;
case RTC_EVENT.RTCE_PROFILE:
this.OnRTCProfileEvent((IRTCProfileEvent2)rtcEvent);
break;
case RTC_EVENT.RTCE_PRESENCE_PROPERTY:
break;

break;
case RTC_EVENT.RTCE_MESSAGING:

I have a registry search launch condition in my deployment project that store the value that it retrieves in a property called DAVERSION.
The problem is that I need to use that property to get another value in the registry based on that value.
e.g. if DAVERSION = "1.0.3 (en-US)"
i need to go to
HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla\Mozilla Firefox\1.0.3 (en-US)\Main
and get certain keys from it.
The problem is that apparently the regkey property cannot take in the DAVERSION property like so
HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla\Mozilla Firefox\[DAVERSION]\Main
Is there a way to do this??

Hi!
I am working on a Storage Area Network (SAN) performance mesuarement system by simulating Microsoft Word usage.
I've used Filemon to get the fileoperations MS Word are using during open/write/save/close on a document stored on another computer. I'm gonna use this information to create a program that simulates many MS Word users at the same time, accessing a file on the Storage Area Network. What is the best way to do this? Should I create a file filter for these operations?
Thanks for any help.
