I have a txt field that is used for comments that is stored in a SQL Varchar(max) field. No matter what I put in there it always is limited to 50 Characters. I was told that it was unlimited pretty much. I need to be able to put in up to 200 characters.
View 6 RepliesA string can contain from 0 to approximately 2 billion (2 ^ 31) Unicode characters. Does this mean the length field for the string is a 4 byte unsigned binary field, or is it a 4 byte signed binary ?
View 4 RepliesI 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.
I have a question, how would i have a button, then when you click it, it puts the text at the text cursor in the RTF?

The structure needed a fixed size of 10 items (9 in programming terms starting from 0) And also out of the 5 items allowed to be chosen as one of the member types for the structure a limit of 5 items of that particular type.

I have two text files with various columns, each column is separated by a tab (" "). What I'm trying to do is the following:-If the values in text file 2 column 1 does not contain any value in text file 1 column 1 then add that field to text file 2 and add a 1 to the second column, like so
String 1 If the value in text file 2 column 1 already appears in text file 1 columns 1 then just add +1 to the value, so if the above value is already in Text File 1 Column 1 and Text File 2 Column 1 then it would appear as.
String 2 And if it was to happen again then
String 3 and so on.I have the following coding so far.
Dim lines1 As New List(Of String)(IO.File.ReadAllLines("File1"))
Dim lines2 As New List(Of String)(IO.File.ReadAllLines("File2"))
IO.File.WriteAllLines("File2", lines1.ToArray) & +1)

I use the above coding, but it removes the second column?

View 5 RepliesI'm trying to simply prove here that this simple function isn't good enough to prevent every sql injection in the world:[code]I know its not secure, because of googling and looking up other questions on url...[code]I then coppied a Chr(8) from the clipboard and replaced the Chr(8) in the textbox with the clipboard contents and still a no-go.It puts the whole string directly into the field w/o problems.I'm using MS SQL Server 2005, and VB .NET 2005.the Text1 field in the database is a Varchar(600) field (don't ask my why its not MAX, its pointless, i know)There are certain triggers on the table that would prevent a mass update such as this and throw some errors if the injection actually worked right.I know parametrized queries are the way to go here and I'm not looking for answers like "well i dunno why it doesn't work, but parametrized queries are the way to go".I'm looking for the ability to prove that our software is broken and that we need to rewrite it using better principles.how to better filter your text fields, the answer is DON'T! Use the parameters! they are much better, safer, and easier!
View 5 RepliesI'm working on this project, and when the form loads it should automatically put the Focus on the username field if it is empty, however if there is a username - put the focus on where you write your message.Below is the code, and it simply doesn't seem to work for whatever reason. I have tried several methods of it, and even commented out every other line of code in the application to make sure there was no interference, and there was none. is there anything that could possibly overwrite the ability to do this? Some setting I need to change? etc etc?

I have been trying to figure out how to take text i have in a SQL text field and create the correct document from it. Here is the info i have in SQL: MIMEType is a string field that contains one of the following "application/pdf", "application/msword", "application/vnd.ms-excel" or a few others. DocumentBody is a text field that looks like "0M8R4KGxGuEPgADAP7/CQA" this continues for quite a bit. FileName is a string field that contains the original file name such as "test.doc" or "test.pdf"
I have tried using the System.IO.FileStream and System.IO.StreamWriter but in the document it actually writes the text that is desplayed in DocumentBody. I assume I am missing some way to decode this using the MIMEType but i just can not seem to find it.
What I need to do is query an iTextSharp AcroField to check if it is rotated, and if so capture the value of the rotation.So If I have the following field:

afi = af.GetFieldItem("fieldName")
What do I need to do to get the rotation (in degrees) of that specific field?

I'm trying to design a words game that's give you the first two letters from the word and you insert the rest to make a word (for now I'm just using "co" as example and I have just one table in the database for it). The word will be written in textbox to be compared to a database field. If the word exist in the field the word will be displayed in a label with blue color and the score will increased by one if not the word will be displayed in the label with red color. This should happen three times with three words and I have different label for each one.
the name of my database is database1 and it have one table "A" wich contain "Comp" and "word". I tried this game with array of word before and it was working. Now I'm trying to use database instead of arrays but its not working. [Code]
