Modify the query to be count(*) instead of a data retrieval operations then you will know the "basic" round trip time. Then, realize, if you are using a Data Set or a EF, or any code generator, there is likely a double trip to load schema information on the query. IE, use data-readers if you like speed and utilized field indexes and native types instead of the column name pseudo index.
Also, remember, local connections can use named pipes, but remote are forced to use TCP-IP under SQL Server or some such.

Is it really only ONE (and exactly one) query to the database?
Or do you get a dataset with many records, then iterate thru the records, and retrieve additional information for each of them by an additional query each?

I need to know how to do a mass insertion from a oracle database into a access database through c#.net coding.
|
|
|
|
|
Access doesn't really have a bulk insert. You'll have to insert the records into the Access database one at a time.

The word is not in the form of smooth throughout, with the following code:
private void Form1_Load(object sender, EventArgs e)
{
label1.ForeColor = Color.Violet;
label1.Text = "From trong suốt";
label2.ForeColor = Color.BlueViolet;
label1.Text = "Màu chữ của form";
label3.ForeColor = Color.DarkOrange;
label1.Text = "Màu chữ của form";
this.TransparencyKey = Color.Wheat;
this.BackColor = Color.Wheat;
}
why not borrow the word transparent form? way to overcome this is not the case? image link: http://freakshare.com/files/1lh6461j/formtran.jpg.html

I have absolutely no idea what you're talking about. "Word is not smooth"?? You haven't given use any kind of context for this problem, like what you're trying to do.
I'm not clicking on a "FreakShare" link. That place has a history, and not a good one.

Yes, I'm not sure I'd like to be asked that as an interview question...

The picture isn't visible; there are plenty of hosts that allow the display of a picture without the need to download it.
The characters will always be drawn one at a time - it's not handwriting where one letter flows into the other. If you're talking about a pixelated word that needs smoothing, then you're looking for what's called "aliassing".

Hi,
Is any way to manage multiple snap shots in single vm using Vestris.VMWareLib in c#.

Wouldn't this question be more appropriate on the VMware forums?? The chances of you finding someone who has experience with this are far FAR greater over there.

Hi,
I have a Windows 8 App , which calls to Twitter via Azure Mobile Service. Intially I was able to get the user's json information ( Name and Profile picture ) by passsing the ID to the following URL:
https://api.twitter.com/users/
However with the change of twitter API 1.1 this doesnot work. I am able to login but unable to retreive the user information in JSON format.
Please help me getting the correct signature in C# in the following format.
https://api.twitter.com/........................................................
I have the following data with me:
User ID
oauth Token
Consumer Key
Consumer Secret
I would need the output in a URL format which when I put in my browser returns the user information in JSON format. I tried refering https://dev.twitter.com/docs/auth/creating-signature but I am unable to get it in URL format.
Your help will be highly appreciated.

This is not a C# question; you should be asking this at the Twitter developer site.

Its typically used by design-time code to get designer services, like the IComponentChanged service or the IWindowsFormsEditorService. Basically it provides an interface for an object to obtain services from another part of the application.
The only time you (almost always) use this is during development of design-time rich controls. For example if you want to add custom property designers to the property grid, you would create a UITypeEditor for your property and override some of the methods, as in this example[^].

I tried to capture webcam video into a mp4 file using the following code.

//capture.FrameRate = 30;
//capture.VideoCompressor = filters.VideoCompressors[0];
//capture.AudioCompressor = filters.AudioCompressors[0];
capture.FrameRate = 29.997; // NTSC
capture.FrameSize = new Size( 320, 240 ); // 640x480
capture.AudioSamplingRate = 44100; // 44.1 kHz
//capture.AudioSampleSize = 16; // 16-bit
//capture.AudioChannels = 1; // Mono
// capture.Filename = "C:\MyVideo.avi";
capture.PreviewWindow = panel1;
if (btnStartVideoCapture.Text == "STOP")
{
counter++;
if (!capture.Cued) capture.Filename = filename + ".mp4";
capture.Cue();
}
capture.Start();
panel1.Visible = false;
}
catch {}
}

if (capture != null) capture.Stop();
if (timer.Enabled) timer.Stop();

{
btnStartVideoCapture.Text = "STOP";
btnStartVideoCapture.BackColor = Color.Maroon;
panel1.Visible = true;
try

capture.Cue();
capture.Start();
timer.Start();

Just replacing an extension of a file does not at all cause a format conversion.
Why did you comment those lines out:
I do not know where exactly you have to set the format you want to get instead of the default format, but that looks like a good place.

There are many resources here on CodeProject for inter-operating with Microsoft Word. Just search for terms like "Word Automation," "Microsoft Word," etc.
You could make your question much more specific, and describe what you've done so far.

This product would have access to everything ever written or recorded, know everything the user ever worked on and saved to his or her personal hard drive, and know a whole lot about the user's tastes, friends and predilections." 2004, USA Today interview

I suggest you put bookmarks in the source document and then insert the text into the relevant bookmarks

Well, Could you tell me your specific word file format? Without that, nobody can insert it.

Hi,
Its some contract agreement with the header , picture and some other agreement details. I need to fill the Customer Name, Date and address from the database.
I already tried the find and replace codes, but since that document has to be reused , finding and replacing text wont solve the problem.
Is there any way i can create an object from one existing document and save it in another name with the replaced texts ?
