Hi
I wrote some winforms app which seems to work but has very ugly problem - it needs near 30 seconds to start.
Application starts in 3 steps -
- splash window is initialized and shown
- main app window is initialized and shown
- splash is hidden.
There is no any data connection touch or any other similar operation at the start.
Measured times to start the app are:
1. splash is shown in 6 ( ) seconds at first and is reduced to 4 seconds in next run
2. Main app window needs about 16 seconds to show.
I am mostly shocked by time to show the splash which is just plain, frameless window with some bitmap loaded from resources.
I have tried different tricks with the assemblies - signed them, added to the GAC and even precompiled, but it doesn't change situation in any significant way.
Time has been measured on my development machine which is Ahlon 2.2 GHz with 1.5BG of RAM so I don't think it is the hardware/os/environment problem.
Could anybody tell me what's wrong?
Any ideas are welcome - I'm getting mad on this 
Thanx
H.

Hi H
Do you compile the application in Release mode?
This can change the startup time dramatically.
If you are already in release mode, then try inserting a few Trace lines here and there and add a System.Diagnostics.TextWriterTraceListener to your application, to find out where all those CPU cycles are going.
TextWriterTraceListener myTextListener = new TextWriterTraceListener(@"C:\debug.txt");
Trace.Listeners.Add(myTextListener);
Trace.Write("BEFORE doing something - the time is: " + DateTime.Now);
...
Trace.Write("AFTER doing something - the time is: " + DateTime.Now);

Hi Jacob
I have tried 3 time measuring methods - user measured time, console output and JetBrains dotTrace.
dotTrace is most detailed, but it has huge influence on measured time.
Your method is probably best since, it has permanent storage of results - thank you for the idea
I have included it in my project and measured times are very similar to those posted before. But I have found something pretty interesting.
There is SplashForm creation in the Program.cs. The SplashForm is derived from NiceDialog class (which is some pre-customized form). Here is part of the log file created with Trace listeners:
2006-09-18 11:44:49; Start of creating splash form
2006-09-18 11:44:52; NiceDialog InitializeComponent start
2006-09-18 11:44:52; NiceDialog InitializeComponent end
2006-09-18 11:44:53; SplashForm InitializeComponent start
2006-09-18 11:44:53; SplashForm InitializeComponent ends
Following code is executed here:
Program.cs
Trace.WriteLine(string.Format("{0}; Start of creating splash form", DateTime.Now));<br />
SplashForm splash = new SplashForm();<br />
splash.Show();<br />
NiceDialog.cs
<br />
public NiceDialogForm()<br />
{<br />
Log("NiceDialog InitializeComponent start");<br />
InitializeComponent();<br />
Log("NiceDialog InitializeComponent end"); <br />
}<br />
protected static void Log(string message)<br />
{<br />
Trace.WriteLine(string.Format("{0}; {1}",DateTime.Now, message));<br />
}<br />
SplashForm.cs
<br />
public SplashForm()<br />
{<br />
Log("SplashForm InitializeComponent start");<br />
InitializeComponent();<br />
Log("SplashForm InitializeComponent ends");<br />
this.lblVersion.Text = "version: "+Application.ProductVersion;<br />
}<br />
Well - it is strange to me. SplashForm constructor is called but its first method is called 3 seconds later. And it's not the time to load next library - they are all declared in main exe file.
There is picture box with some resource based bitmap on the NiceDialog form. I have heard that resources may make program execution slower, so I decided to reset pictureBox Image propery - so it doesn't show anything right now. Here is part of log file with this operations:
2006-09-18 12:25:45; Start of creating splash form
2006-09-18 12:25:45; NiceDialog InitializeComponent start
2006-09-18 12:25:49; NiceDialog InitializeComponent end
2006-09-18 12:25:49; SplashForm InitializeComponent start
2006-09-18 12:25:49; SplashForm InitializeComponent ends
As you can see, NiceDialog execution time become normal, but NiceDialog InitializeComponent gone much higher (4 seconds!!!)- I have no idea why.
Best regards

Hi Hubert
Could you dump the contents of InitializeComponent from NiceDialog here - so we could have a look.
We should be able to find the problem

Here is the code of NiceDialog InitializeComponent:
<code>
private void InitializeComponent()
{
System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(NiceDialogForm));
this.pictureBox1 = new System.Windows.Forms.PictureBox();
this.panel1 = new System.Windows.Forms.Panel();
this.panel2 = new System.Windows.Forms.Panel();
((System.ComponentModel.ISupportInitialize)(this.pictureBox1)).BeginInit();
this.SuspendLayout();
this.pictureBox1.Dock = System.Windows.Forms.DockStyle.Left;
this.pictureBox1.Location = new System.Drawing.Point(12, 12);
this.pictureBox1.Name = "pictureBox1";
this.pictureBox1.Size = new System.Drawing.Size(131, 264);
this.pictureBox1.SizeMode = System.Windows.Forms.PictureBoxSizeMode.StretchImage;
this.pictureBox1.TabIndex = 0;
this.pictureBox1.TabStop = false;
this.panel1.Dock = System.Windows.Forms.DockStyle.Fill;
this.panel1.Location = new System.Drawing.Point(155, 12);
this.panel1.Name = "panel1";
this.panel1.Size = new System.Drawing.Size(228, 264);
this.panel1.TabIndex = 2;
this.panel2.Dock = System.Windows.Forms.DockStyle.Left;
this.panel2.Location = new System.Drawing.Point(143, 12);
this.panel2.Name = "panel2";
this.panel2.Size = new System.Drawing.Size(12, 264);
this.panel2.TabIndex = 3;
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.BackColor = System.Drawing.Color.Gainsboro;
this.ClientSize = new System.Drawing.Size(395, 288);
this.ControlBox = false;
this.Controls.Add(this.panel1);
this.Controls.Add(this.panel2);
this.Controls.Add(this.pictureBox1);
this.DoubleBuffered = true;
this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
this.Icon = ((System.Drawing.Icon)(resources.GetObject("$this.Icon")));
this.MaximizeBox = false;
this.MinimizeBox = false;
this.Name = "NiceDialogForm";
this.Padding = new System.Windows.Forms.Padding(12);
this.ShowIcon = false;
this.ShowInTaskbar = false;
this.SizeGripStyle = System.Windows.Forms.SizeGripStyle.Hide;
this.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen;
this.Text = "SplashForm";
((System.ComponentModel.ISupportInitialize)(this.pictureBox1)).EndInit();
this.ResumeLayout(false);
}
</code>
There is nothing unusual for me - it's just what VS2k5 has made.
I still think about this release/debug issue - you have mentioned it in the first post. I haven't seen such a big difference, so maybe this is my problem? How can I check if the final assembly is optimized or not? The project seems to be ok - "Optimize code" flag is set.
Best regards
Hubert

Hi Hubert
If I were you, I'd set the Trace.WriteLine statements at the beginning and end inside the InitializeComponent method.
Then move the Trace.WriteLine "end" halfway up, then halfway again, etc. until you find THE line that takes all the time.
I'm pretty sure there is one or two single lines taking up all the time.
Let me know when you're closer to the problem.
Kind regards - Jakob

Yes! I have probably found it. I decided to comment following line from the InitializeComponent method:
this.Icon = ((System.Drawing.Icon)(resources.GetObject("$this.Icon")));
Application needs just 1 second to show SplashForm now, so it is 4 times better than in the early begining of the optimalization.
But I don't have idea how to set icon and image in the picturebox faster than loading from resources. I don't want to have them in separate files in the app directory - I think it is not profesional.
Best regards
Hubert

Hm.... weird!
Is it a homemade icon..? There may be some bug in the icon file.
Try setting the icon to the standard icon and check again for speed comparison.

I've noticed that getting data from a resource can be expensive. IIRC it tries to locate explicit resources for the current language (such as en-us)in a subfolder and takes a file not found exception if it's missing, and then goes on to do a lot of other stuff too. If you run a profiler on the code you'd see some of this going on by looking at the objects that get created behind your back.

Sorry for long time no answer, I am still in time-tracing business
Loading icon from external file (plain .ico) takes near no time. Loading it from the dll's resources takes 4 seconds. The same situation is with any other bitmap. I am sure it is my mistake but question is WHAT'S WRONG?

Do you mean MS CLR Profiler?
I have downloaded and tried CLR Profiler from Microsoft, however it doesn't work with my project. I run the CLR Profiler, loaded and started my app and bang - the profiler shuts down without any message. Have you noticed such kind of behaviors?

Frndz,
I have a image control of type html in DotNet2.0.
I want to create the object of that HTMLImage control in my codebehind.
This is how I try creating the object the HTMLImage object
CType(Me.FindControl("ctl00_cphMaster_imgDate"), HtmlImage).Disabled = True
My control and its runtime generated name is listd below:

Hi,
I have a C#.net application. I have two C++ dlls with same name (but different version numbers that i see in the dll). When I use Dll Import to invoke methods on each dll separately in two different applications, all the methods in both the c++ dlls work fine.
But if i tend to use dll import and invoke the functions in the two dlls, the first dll's methods are executing fine but when the second dll's methods are invoked, there is an error stating "cannot load the second dll. method not found".
I wonder if it is something to do with loading two same named dlls in the same memory of an exe...
Please help in identifying the cause and kindly clarify my doubt.
Many Thanks.

I am dealing with something related to .NET and C# and wonder about your comment. Hope you are clear in understanding my problem.

By cross posting you minimize your chances of getting relevant help, partly because you annoy other people, partly because you don't use the message boards in the best way.
If you feel that you have to draw attention to the question from different message boards, post the question in the most relevant board, and post links to the question in the other boards. That way you get the replies in a single thread, and people can see what other have replied so that they can cooperate in helping you.

Is there any "approved" method of controlling the order in which delegates are invoked when an event occurs, other adding them to the event in the "right order".
Phil Daniels
|
|
|
|
|
You could try delegating the delegate such that the there is exactly one delegate within the event and the other delegates are called by this ?
event calls B (single)
B calls others in the desired order. The other delegates could be internally maintained, perhaps as using a order::delegate value in a Dictionary
[?]
namaste,
Nitin

I've done something similar, which is to create another event that's fired first, the two hi-priority delegates subscribe to it, the rest subscribe to the other event which is fired (ie the On.... method is invoked) after the first is done. It'll do for now.
Thanks for your assist - rgds phild

Hi,
Im creating Setfile for my Windows application and i can able to install it after creation, i want to add uninstallation option also with this how can i do it.
Thanks in Advance...

You don't. It is already handled by Windows Installer, look at your Add/Remove programs.

I have done my project in .net
When i run my defualt.aspx, sometime it will show runtime error at web config. But sometime it will not.
What will this issue cause by?
the description of my error is:
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Try following in your web.config file and you should be able to see more descriptive error.
customErrors mode="Off"

Hello there
I had this fun idea about writing a program were you can set rights on other accounts(if you are admin etc), and also list what accounts exists on the computer. Everything I intend to do you can already do in windows xp but I want to do it anyway and do it in my program instead. One example would be to set account x so you cannot login afer 10pm.
Problem is, I know very little about what I suspect is needed to do that. I'm suspecting I will have to manipulate the windows shell in some way perhaps?
Anyway, if anyone has any suggestions were I could start looking for information or suggestions how to do this feel free to reply. I know mostly c# but have played around with c/c++ and I guess I could learn it again if needed.

the upper one is the JavaScript code and the lower one in HTML code that I am using in ASPX file for applying the onmouseover functionality on the login button.
Now I would like to use this button (login) as to navigate to some other page (main.aspx ) after clicking it.
Can somone please tell me the function that I should write in the codebehind page for doing as above................ (I am working in C#)
