Well whatever API you are using to send data already should be configurable to work via a proxy. Check the docs for the particular API you are using. I think the standard .net http stuff uses the WinINet API underneath which I believe fiddler will just pick up automatically anyway without any config.

There's an MSDN article here on proxy configuration in .net: http://msdn.microsoft.com/en-us/magazine/cc300743.aspx[^]

There's a fiddler FAQ here on how to configure different types of app: http://www.fiddlertool.com/Fiddler/help/hookup.asp[^]

(Or you can configure fiddler as a reverse proxy http://www.fiddlertool.com/Fiddler/help/reverseproxy.asp[^])

Oh, and there's a whole article on fiddler debugging on MSDN here: http://msdn.microsoft.com/en-us/library/bb250446.aspx[^]

There's loads of info on this. Just Google it.

Great Simon!

Just want to confirm with you from what I learned, we can use WebRequest.Proxy to explicitly set the proxy to be used for each web request?

You're going to get it as a stream from DirectX, same as the video, if the webcam has an audio stream.

CodePrimitiveExpression Class

Hi All,

Regarding this C# statement:

CodePrimitiveExpression stringPrimitive = new CodePrimitiveExpression("Test String");
System.Console.WriteLine(stringPrimitive);

the output will be "Test String", is there anyway that i can get rid of the double quotes, so the output can only be:

Test String
instead of
"Test String"

Many Thanks

Andie

Did you actually try it?

This code:

CodePrimitiveExpression stringPrimitive = new CodePrimitiveExpression("Test String");
System.Console.WriteLine(stringPrimitive);

Outputs this:

System.CodeDom.CodePrimitiveExpression

This code:

CodePrimitiveExpression stringPrimitive = new CodePrimitiveExpression("Test String");
System.Console.WriteLine(stringPrimitive.Value);

Outputs this:

Test String

No quotes, see. Cool | :cool:

Is that what you want?

Does anybody know what the equivalent function is for ldexpl in .Net?

ldexpl is from math.h in C++, but I want to use it in .Net.

Thanks

center picturebox inside panel

hi,
(this is only a design issue).

In a particular form i load pictures to a picturebox from a Database
(or when uploading with browse).
That picturebox is inside a panel.
The picturebox as the sizemode propriety set to AUTOSIZE (remember this).
What i want is to center the picturebox inside the panel!!!
It looks simply right? Wink | ;)

I got width and height of both panel and picturebox and did the math,
but ... because it is AUTOSIZE, couldn´t center it because i got width and height of the picture original size(the one i load in picturebox)!!!
I can´t get the width and height of the picturebox when AUTOSIZED in order to center it

Want is the propriety to get width and height of AUTOSIZED pictures??? Confused | :confused:

Thanks

Re: center picturebox inside panel

Christian Graus31-Jul-08 13:43

There is none. Autosized means the control is redrawing your pic at the size it wants to.

To get that sort of control, you should draw the pic yourself.

Can't you just dock the picture box in the panel, and let the picture box center the image?

Can't debug CLR locally in VS 2008

JMichael246831-Jul-08 10:54

I have a CLR UDF that I created a while back and I could debug it locally and remotely. However, I can no longer debug, or step into, it at all. In the output window in VS it says that the attachment succeeded, but, it never makes it to the break point in test.sql or any other break point. I have checked and rechecked the properties and all is in order. I know I haven't changed anything. I also followed a simple tutorial from the web (a couple of them) that don't do anything but return a string saying "hello", and the same problem occurs.

Funny thing to mention is that I was having the same problem yesterday, but it would work off and on. It worked three different times but doesn't seem to want to work at all now.

I have also deleted the binaries and redeployed and that doesn't seem to work either.

Convert DateTime to Date

Verghese31-Jul-08 8:59

31-Jul-08 8:59

In my DataSet, I have a field called "ADMISSION_DATE" in the format of DateTime, which upon displaying in my Report showz up as, lets say, "08-29-08 12:00:00".

3rd Line displays the Date (08-30-08) as required but 4th line displays it as DateTime (08-29-08 12:00:00).

But I want only the date thing (i.e. 08-29-08). And in dataset I don't see any direct DATE conversion methods. Please help.

row["ADMISSION_DATE"] = DateTime.Parse(row["MM"].ToString() + "/" + row["DD"].ToString() + "/" + row["CC"].ToString() + row["YY"].ToString().ToString()) ;

DateTime newDT = new DateTime();                         //Line-1
newDT = Convert.ToDateTime(row["ADMISSION_DATE"]).Date;  //Line-2
MessageBox.Show(newDT.ToShortDateString());              //Line-3

row["ADM_DATE"] = newDT.ToShortDateString();             //Line-4

Thanking you in anticipation.

Hi,

If your column ADMISSION_DATE is datetime, you cannot store only the date portion. Time is set to default if it's not specified. However when you get the datetime from the row, you can truncate it just as you have done.

A DateTime value always has a time component, even if it's zero. The Date property returns a DateTime value where the time component is set to zero, just as you do in line 2.

Verghese wrote:
row["ADMISSION_DATE"] = DateTime.Parse(row["MM"].ToString() + "/" + row["DD"].ToString() + "/" + row["CC"].ToString() + row["YY"].ToString().ToString()) ;

If you already have the components of the date as numbers, don't format them into a string just to parse into a date. There is a perfectly good constructor for the DateTime structure that takes numbers:

row["ADMISSION_DATE"] = new DateTime((int)row["CC"] * 100 + (int)row["YY], (int)row["MM"], (int)row["DD"]);

Verghese wrote:
3rd Line displays the Date (08-30-08) as required but 4th line displays it as DateTime (08-29-08 12:00:00).

You are storing a string in the field, so if you display it as it is, it can't display in any other way than the way that you formatted it. The only chance that it would display with a time component, is if it's parsed into a DateTime value and the formatted into a string again using a different format.

Despite everything, the person most likely to be fooling you next is yourself.

Guffa, I understand that, storing a value as string cannot be displayed in any other formats unless until we parse it into some other formats.

But that's the reason why I'm parsing it into DateTime format. see the code one again......

row["ADMISSION_DATE"] = DateTime.Parse(row["MM"].ToString() + "/" + row["DD"].ToString() + "/" + row["CC"].ToString() + row["YY"].ToString().ToString()) ;

The row["MM"].ToString is a String, but I'm finally parsing it into DateTime. And after execution I could see that the "ADMISSION_DATE" field type in DataSet changes to DateTime. So from this its clear that it's getting stored as DateTime and the field type is also DateTime.

But the problem is to extract only the date thing, when I call the DataSet rows.

Hope I dindn't confused you.

Yes, you are storing a DateTime value in the field, and the value has a time component that is zero. Then you read the field, convert the DateTime value to a DateTime value, and use the Date property to get a DateTime value where the time component is zero from the DateTime value where the time component already is zero. Then you convert the value into a string using a format that does not even include the time component that is zero.

As the value that you finally store as a string in a field doesn't have any time information at all, the problem is not in the code that you have shown. As I said before, the only chance that this value is displayed with a time, is if it's once again parsed into a DateTime value and then formatted into a string with a different format.

Despite everything, the person most likely to be fooling you next is yourself.

Dates and times should always be stored as DateTime (when available). If they aren't, then you run into these kinds of problems.
Any formatting should be performed when the value is displayed (or written), not in the database.

And please use an ISO 8601-compliant format, e.g. YYYY-MM-DD

you said Reports
So if its just a question about displaying the data on the report ,
use string functions to eliminate the extra time .
