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);

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.

No, if you just want the window to move a bit, DirectX is certainly not required. In fact, I'm not sure how it could help.
All you need to do is create a loop and set the window position within it to differing values, and possible call Application.DoEvents() to make sure the app responds to the events for you.

 Hi Good to See you.
For shaking two windows form in same machine or remote machine you can use Remoting Concept of .NET.In Three steps you can achieve this.
1. Create Server:That handle your request
2. A client: request Sender
3. your From.
For details mail me.

Please always search on your own before posting.
If you would just have searched for 'shake form' with this little field right beneath the CodeProject logo you would have easily found this.

Hey!
I am using System.IO.serialport(Framework 2.0 beta 1) to communicate throw the serial port(com/USB).
I have connected a function to the event DataRecived, and there is a steady incoming dataflow on this serial port. To be able to read the data I had to set DTEnabled = true.
Problem: Now I need to send some data back out on the serial port, but as long as I have a steady dataflow in to my program (that im reading) I cant send?
The data is not received on the other end.
