I tryed this.
private int pointCount = 0;
private int iterationsCount = 0;
public System.Timers.Timer tmrLoading = new System.Timers.Timer();
public frmLoading()
{
InitializeComponent();
}
private void frmLoading_Load(object sender, EventArgs e)
{
tmrLoading.Interval = 100;
}
private void frmLoading_Shown(object sender, EventArgs e)
{
tmrLoading.Start();
tmrLoading.Elapsed +=new System.Timers.ElapsedEventHandler(tmrLoading_Elapsed);
}
void tmrLoading_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
Application.DoEvents();
if (iterationsCount <= 2)
{
if (pointCount <= 10)
{
this.lblLoadingText.Text += ".";
pointCount++;
tmrLoading.Start();
}
else
{
this.lblLoadingText.Text = "Loading";
iterationsCount++;
pointCount = 0;
}
}
//throw new Exception("The method or operation is not implemented.");
}
but i had an error in this row
- this.lblLoadingText.Text += ".";
"Cross-thread operation not valid: Control 'lblLoadingText' accessed from a thread other than the thread it was created on"
what i do incorrect?

Like I said, you have to invoke the method.
Invoke() is a member of control.
this.Invoke ... when this is your Form

Hello,
I would add a method which sets the Text, and check there if Invoke is required.
private delegate void SetLoadingTextDelegate(string actText, bool append);
privat void SetLoadingText(string actText, bool append)
{
if(InvokeRequired)
{
Invoke(new SetLoadingTextDelegate(EnableTimer), new object[] {actText, append});
return;
}
if(append)
{
this.lblLoadingText.Text += actText;
}
else
{
this.lblLoadingText.Text = actText;
}
}
void tmrLoading_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
if (iterationsCount <= 2)
{
if (pointCount <= 10)
{
SetLoadingText(".", true);
pointCount++;
tmrLoading.Start();
}
else
{
SetLoadingText("Loading", false);
iterationsCount++;
pointCount = 0;
}
}
Application.DoEvents();
}
Hope it helps!
All the best,
Martin

aha.. i tryed to use property but not method...
ok. i'll it to. thanx!
but why thys code dont work?
public partial class frmLoading : Form
{
private int pointCount = 0;
// private int iterationsCount = 0;
private System.Timers.Timer tmrLoad = new System.Timers.Timer();
public frmLoading()
{
InitializeComponent();
}
private void frmLoading_Shown(object sender, EventArgs e)
{
tmrLoad.Interval = 1000;
ChangeLabelText();
}
private void ChangeLabelText()
{
for (; ; )
{
if (pointCount <= 10)
{
lblLoadingText.Text += ".";
tmrLoad.Start();
pointCount++;
Application.DoEvents();
}
else
{
lblLoadingText.Text = "Loading";
iterationsCount++;
pointCount = 0;
}
}
}
}
main form --------------------
private void frmMain_Load(object sender, EventArgs e)
{
this.Visible = false;
}
private void frmMain_Shown(object sender, EventArgs e)
{
frm.Visible = true;
LoadSettings();
LoadImages();
LoadControlsPositions();
frm.Dispose();
this.Visible = true;
}

Sorry, I have no idea what you try to do here!
What is the timer doing here? You haven't added a eventhandler forthe timer.
All the best,
Martin

ok. timer can go to hell 
I want that main form is invisible while images are loading. so I do this:
private void frmMain_Load(object sender, EventArgs e)
{
this.Visible = false;
}
right?
and after images are loading - form must be showed. so
private void frmMain_Shown(object sender, EventArgs e)
{
LoadSettings();
LoadImages();
LoadControlsPositions();
this.Visible = true;
}
right?

Like Christian said at the beginning, you should use "Application.DoEvents();".
private void frmMain_Load(object sender, EventArgs e)
{
this.Visible = false;
Application.DoEvents();
}
tradakad wrote: private void frmMain_Shown(object sender, EventArgs e)
{
LoadSettings();
LoadImages();
LoadControlsPositions();
this.Visible = true;
}
Again, DoEvents. But which event are you connected too?

while main from is hiding - i show loadingForm
private void frmMain_Shown(object sender, EventArgs e)
{
frm.Visible = true;
Application.DoEvents();
LoadSettings();
LoadImages();
LoadControlsPositions();
frm.Dispose();
this.Visible = true;
}
and if dont write Application.DoEvents(); label ot the loading form is not visible 
when LoadControlsPositions(); is complete - i kill frm and show the main form again..

{
this.Visible = false;
frm.Visible = true;
Application.DoEvents();
}

The following line of code:
this.lblImportFile.Font = new System.Drawing.Font("Tahoma", 8.25F);
is throwing the following exception:
{"Exception has been thrown by the target of an invocation." }
and I have no idea why. does anybody have any ideas?

Sorry forgot to mention I am using Visual Studio 2003 with .NET Framework 1.1
|
|
|
|
|
I have narrowed it down to an "Overflow or underflow in the arithmetic operation." but I still don't know why.
|
|
|
|
|
then u can see the inner exception, then u came to know whats the problem.
Ex.InnerException.Message
With regards

if you can catch the exception, show it with ToString() method.
DO NOT USE MESSAGE PROPERTY
ToString() shows everything there is, Message only gives a short one-line summmary.

Hi to all,
I want some information about the playing the multiple video clips on the web page one by one. Please help me how can i do it.

you might want to take a look at Silverlight. I remember seeing a demo at the Remix convention about several video clips being play simulatenously on a webpage. Go to http://www.silverlight.net
Edit:
Here is a tutorial which explains how to use Silverlight and streaming videos via webpage
http://aspalliance.com/1342_Streaming_a_Silverlight_Media_Application_from_Silverlight_Live#Page5
In particular go to the section titled " Invoke multiple video files from a single web page" which is the answer you are seeking.
Silverlight rocks when it comes to media streaming.

But i am using shockwave flash player object/component here. It does not shows the properties and events. so how can i use it.
Pravin

It doesn't expose properties that you can natively hook into through C#. The properties are all controlled through HTML using the PARAMS and EMBED tag on the object. Here's an example:
<OBJECT classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0" WIDTH="550" HEIGHT="400" id="superflashMovie"><PARAM NAME=movie VALUE="superflashMovie.swf"><PARAM NAME=quality VALUE=high><PARAM NAME=bgcolor VALUE=#FFFFFF><EMBED src="/support/flash/ts/documents/superflashMovie.swf" quality=high bgcolor=#FFFFFF WIDTH="500" HEIGHT="350" NAME="superFlashMovie" TYPE="application/x-shockwave-flash"
PLUGINSPAGE="http://www.macromedia.com/go/getflashplayer"></EMBED></OBJECT>

Well, the only way that I can think (off the top of my head) to do this would be to use javascript to play the next movie in a sequence after a period of time. Assume that you've given the Flash object an id of "mySecondMovie", you could do this to trigger the movie:
<SCRIPT LANGUAGE = "JavaScript">
<!--
var secs
var id = null
var isTimerRunning = false
var delay = 1000
function InitializeTimer()
{
secs = 15
StopTimer()
StartTimer()
}
function StopTimer()
{
if(isTimerRunning)
clearTimeout(id)
isTimerRunning = false
}
function StartTimer()
{
if (secs==0)
{
StopTimer()
playMySecondMovie()
}
else
{
self.status = secs
secs = secs - 1
isTimerRunning = true
id = self.setTimeout("StartTimer()", delay)
}
}
function playMySecondMovie()
{
if (document.mySecondMovie)
{
if (document.mySecondMovie.Play)
document.mySecondMovie.Play();
}
}
</SCRIPT>Then, in your body onload, you would call InitializeTimer.

Thanks for it. but how can i calculate the length of the first movie. Is there any event occures at the end of Video clip? so that I can check it?
Pravin

Not that I'm aware of. Mind you, if you have the flash itself, you could always call the javascript to play the next movie using an ActionScript command:
getUrl("javascript:playNextPage();")Then, you would implement the playNextPage javascript in your page to play the next movie as outlined above.
