Asp.net - Determine File Size Before Upload?

Jul 8, 2010

So we're having this problem. A user goes to upload a file, and if it's above 10MB, it just kind of times out the page, and clears, and no good error is thrown to describe what happened. Ideally, we would like to examine the file size when the user chooses the file they want to upload but I don't know if this is even possible. Our framework is built with ASP.NET, VB.NET, and Javascript (and ExtJS 3.0), and it runs in IE.

Scan A Text File To Determine If It Is A Text File And If It Contains Any Non-ASCII Characters?

Jan 27, 2012

what would be the optimum code in VB2010 that check a file to determine:

1) is it a text file, and

2) if it is a text file, does it contain any non-ASCII characters

Note that LF, CR, and EOF would be expected, and should not be flagged. I can think of 3 - 4 ways to do it, but there may be a 'best' way in terms of simplicity and speed.

Determine Icon Size On Desktop?

Sep 6, 2010

I am running Windows 7 home premium (64bit) and writing programs using VB 2010 Express.

I have found a user can change icon display size using 'control panel' > 'appearance and personalization' >'Display' where they can select small, medium or large. The result, even though the icon heigth & width values are not changed, the apparent icon size on the desktop(and also text size in controls) is changed. Hence, if the user has chosen a larger icon size that I have on my machine, text in a button is larger and may not be completely visible.Knowing the user font size choice, I could adjust font size as required.[code]...

How To Determine Size Of Dynamic Array

Jul 28, 2011

I'm trying to find the sum of all the digits that make up the number 2^1000, which you may have guessed is from Project Eula. I think it's good so far except I'm just learning about arrays and dynamic arrays, so how will I know what the size of the index will be so I can specify when the Do loop should stop so I don't get an indexoutofrange exception?

vb.net
Dim BigNumber As Double = 2 ^ 1000
Dim DigitArray() As Char = BigNumber.ToString.ToCharArray
Dim Index As Integer = 0
Dim SumOfDigits As Integer = 0

Text - Ensure That A File Has Unique Line If The Size Of The File Is Very Big

Apr 4, 2012

Language: vb.net
File size: 1GB, and stuff.

Encoding of the text file: UTF8 (so each character is represented by different numbers of bytes).

Collation: UnicodeCI (when several characters are essentially the same, the most popular version will be the one unique.). I think I know how to handle t his one.

Because each character is represented by different numbers of bytes and each line has different numbers of characters, the number of bytes in each line also vary.

I suppose we have to compute hash for each line. We also need to store buffers location where the line each. Then we have to compare buffers. Then we will check whether the same line shows up or not.

Size Rich Text Box Using Size Of Text?

Oct 18, 2009

I have a rich text box that have a paragraph in it (the parragraph may change). The user is able to decide what type and/or size of font he whishes to view the text in. My problem is that not more that an average of four words per line should be displayed per line. My idea was to size the rtb so that it automatically wrap the text to and average of 4 words per line. This I would do by determining the average width of a word (number of characters) in the paragraph, multiplying it by the width in pixels or twips of a character and then multiplying by 4 to get the average required length of a line. It does not need to be exact as long as I can get as close as possible to 4 words per line. Sample text:

My Father walks to the market every day to buy fresh bread and milk for the house.

Result expected:

My Father walks to the market every day to buy fresh bread and milk for the house.

Notice some lines may be slightly longer as long as the average is 4 words per line.My problem is that I dont know how to determine the width of a character in order to ultimately determine the width of a sentence.

How To Determine A New Line In A Text Box

Mar 16, 2010

i have designed a form that generates e-mails for outlook. the form has a textbox which allows the user to write extra notes. these notes are then added to the e-mail body at the end.

here is the issue, suppose the user wants to enter the following as extra notes.but when i actually add this to the end of the e-mail body i get something like this

"Please send us a replyyours truly,user" i has similar issues when i was generating the e-mail body as i was not using the default SMTP client server but some other methods to generate the e-mail

i know how to make the characters come to the next line, but i do not know how can i determine when the user has moved to the next line is there a way to determine this, and if there is how can i replace it with this character " %0d%0A"

Text Phrase Identification - Determine Type Of Input?

Feb 22, 2009

I'm trying to identify if the input of a textbox is non numerical, which cannot be converted to an integer/double for calculation. I do this by converting the input1.text to ascii, and looking at the value to determine the type of input. My question is whether there is any way I can analyze the whole input character by character? Asc() only gives the ascii value of the first character, but what if the input is "9W" etc? Such inputs will pass my character test, but cannot be converted to an integer.

Determine If Row In File Is Date

Jun 13, 2011

When scanning a data file of this kind of form:

21/02/11 11:00:23, true, false
22/02/11 02:03:43 AM, true, false
22/03/11, false, false
2011-05-21T12:30:20, true, true

The 2nd and 3rd row are not important. How can you, by scanning a file, determine if a row comprises of dates, particularly when they have inconsistent formats? In the example above, for instance:

1) 1st line is date and time
2) 2nd line is date and time but also AM/PM
3) 3rd line is only date
4) 4th line is GMT format.

I'm not requesting code, but perhaps an algorithm or some guidelines on how to achieve this.
