I want to know how long a particular function in my program takes to run. How can I get the number of milliseconds between two DateTime objects? Or is there a better way to do this?

I'm no .net expert so I can only give you the Win32 way.
Use QueryPerformanceCounter() and QueryPerformanceFrequency()
Very high resolution timer, I used it all the time when doing game development on Win32. Milliseconds aren't really good enough for this sort of timing btw.

|
|
|
try this (C#)..
double totalMillisecs = (dt2-dt1).TotalMilliseconds;

Thats what I was after. Thank you.

U can use the following idea..
int t1= Environment.TickCount;
function();
int t2=Environment.TickCount;
int t3=t2-t1;
Console.Writleln("Time consumed : " + t3.ToString());

Hi,
I would like my web app to output to a webpage via Response.Write() upon pageload... But i dont want it to just blurt it out at the top of tha page as it seems to always do.
Could anyone please tell me how I go about making sure my Response.Write() only outputs between given points/Html tags/etc?
It's not somthing i can simply output to a pre-placed text object as it contains HTML formatting which Response.Write handles and it must also output between specific CSS class tags to recive the correct formatting.
Is Response.Write() what i should be using? or is there another method i should consider?
Thanks

You can position labels in your HTML and set their text instead. Otherwise, you have no option. it's all to do with in what order the code is called.

If i want to select some icon or a part of text in word or visualstudio editor or select item in the itemlistbox i see a select blu rectangle.
How can use that in my application? i don't want to create it creating a alpha blu fillrectangle with gdi+.
But i want to use methods like ControlPaint
tnx

Which control do you use ?
if label, then you cannot select the text.
if textbox or richtextbox, then you can select the text using method "Select(int start, int length)".
e.g.
this.textbox.Select(0, 2);

a small problem
i have two forms one mainform and one frmtoolbar ,
mainform has a menuitem mnu1 and frmtoolbar has a button btn1
in the mainform i am calling frmtoolbar as follows
myToolbar = new frmToolbar();
this.AddOwnedForm(myToolbar);
myToolbar.Visible = false ;
myToolbar.Show();
i want to call menuitem mnu1 from mainform
on the button click event of frmToolbar the btn1
i am getting non - static field error if i make the menu item public in the main form
i am not sure if this can be solved using delegate
please give me an exxample if this is
thanks

In you're event handler for the button on the frmToolbar Form you can use the Owner property to access an instance of the MainForm. So something like this will work (in frmToolbar)
private void OnButtonClick(object sender, EventArgs e)
{
((MainForm)this.Owner).mnu1_Click(sender, e);
}
You're getting a non-static field error because (I'm taking a logical guess now) that you are referencing the class (hence you have to use a static property / method) when you really want to reference an instance of the class (and get member property / methods).
You don't need to use delegates, you're just not referencing an instance of the MainForm class.

I have a repeater control to display thumbnail pictures. The itemtemplate is made of a web image control. When user clicks on the thumbnail picture, I want it to display a larger image in a web image control and display the image description in a label( the image description is saved in database).
My current code is :
I have a getPhoto function which will get the thumbnail pictures through IhttpHandler and bound to the repeater control.
Then I have a repPhotoG_ItemDataBound function, here I add the javascript to the image html control and call a javascript to pass the thumbnail imagename as parameter and show the large image.
Now, I can get the thubnail picture and display the large images, but I just don’t know how to get and display the image description. Please help!!
private void repPhotoG_ItemDataBound(object sender, System.Web.UI.WebControls.RepeaterItemEventArgs e)
{
//finding repeater item Image
System.Web.UI.HtmlControls.HtmlImage img=(System.Web.UI.HtmlControls.HtmlImage)e.Item.FindControl("iPhoto");
//create a relative path for image and add onclick function
img.Src=img.Src.Replace('\\', '/');
string Description="";
string Image;
Image=IMGpath(img.Src);
img.Attributes["onclick"]="showImg('"+Image+"')";
}
function showImg(imgName)
{
imgOn = ("" + imgName);
document.imgLarge.filters[0].Apply();
document.imgLarge.src = imgOn;
hdr.innerHTML=imgName;
document.imgLarge.filters[0].Play();

my project is to implement a basic inventory system using an array of structs.
the struct contains an int, itemNumber, and a method, AddItem.
if i create an array of 100 of the structs, it seems to mean i have 100 copies of the method.
i could make the method static but i'm limited to accessing only static members.
i'm wondering if there isn't a better way.
it seems i should keep AddItem in the same struct definition as itemNumber so i can make itemNumbers' access private.
with this scenario:
1) would i have 100 occurrences of AddItem?
2) is there a better approach than what i've outlined?
i appreciate any comments.
thanks.

I'm really lost on why you have an AddItem method inside the struct. If you want the itemNumber to be read only, just set it in the constructor and have a property with only a getter. If you want to automatically increase the itemNumber, you can have another static number in the struct and when a new item is created, assign the itemNumber to the static number and increase the static number by one.

No, the instructions which constitute a given type's methods only exist in one place per AppDomain.

Maybe  (the context is not defined well enough)

The method is not stored in the data of the struct. Not even a reference to the method. Not even if the method is virtual.
If the int is the only data in the struct, the total size of an instance of the struct will be exactly the same as the size of an int, e.g. four bytes.

Hey All,
Not quite sure where I should post this as I'm not really sure what is going on nor can I find anything out there that really helps me with my problem, hence why I'm posting this :\
I have an windows application written in c#. I needed to have the ability to show a certain web page depending on actions taken by the user and I wanted to make it look and feel like the web page was actually part of the windows application so I created a form and added an instance of the Microsfot Web Broswer control to it after having seen an example online using this.
Pretty much everything worked perfectly with it until I went to distribute an installer for the application. The problem is that the installer won't include the Interop.SHDocVw.dll and I have to manually copy this dll to the install folder. A major pain when trying to install this on numerous client machines to say the least. It has no problem with the AxSHDocVw.dll and this is copied in.
I've tried removing and adding the references a number of times. I've refreshed the dependencies to the installer. I've tried to add this dll to the installer manually, both the Interop.SHDocVw.dll and the SHDocVw.dll to no avail. I always get an error message that it is already included in the references, which it is, and the installer build fails.
Can someone please tell me what I need to do to resolve this? Or if not, maybe another way of doing what I'm try to acheive.
TIA,
Brian

What are you using for the installer, if you're using the one bundled with VS.NET then I think you can just open up a filesystem like view and use the context menus to add the dll, install it to the same directory as the application (as you're doing manually at the moment).
If you're using a "third-party" installer then I'd expect you'd know what you're doing unless there was a wizard provided which built up all the references. If you're using something like NSIS then I'd expect you to know better since you wrote the script .

Hi:
I'm using codedom to generate source code and I need to generate something like the ternary operator in C# ( ? : ) but I don't know how to do it, I can't find any class in the System.CodeDom namespace to do this.
Thanks

friends i m having problem in displaying the form in a loop:
do
{
this.boardRenderer.DisplayBoard(gameBoard);
<other code>
}while(<the game doesnt ends>)
the DisplayBoard function draws on the form but when it is called in from a loop, the main form is not displayed until the processing of the loop is over (END OF GAME IN MY CASE :'( ) how can i make it display the form while processing other code?? PLZZZZ HELP!!

That is normal, the repaint happens in the same thread. You will need to have a worker thread that draws on the form using delegates.
I am sure there is a tutorial here on code project.
