I have a CSV file where the values are in double quotes and seperated by a comma. I'm getting incorrect data if I try to seperate the string with my Split function. How do I do it?
Example:[code...]
I'm trying to read a csv file with comma separated. Problem is inside the file, it has one column which original value already contains Comma. Here is the example
[Code]....
So, when I Split the string with Comma, it gave me problem. Actually total it has 6 columns. But because of internal comma, it gave me 7 columns. And this CSV format can't change so I must deal with this problem. And so here I come out with a solution (because of its too long, I looking for better idea and solutions from you guys ):

View 6 RepliesI have a problem that seems trivial. In an argument to an activity I need to supply a path.
This is done by this code:
String.Format("a
-bd -y -tzip {0} {1}* -r",
Path.Combine(BinariesDirectory,
"output.zip"),
BinariesDirectory)
However, the directories parameters contain spaces so they have to have quotes around them. I tried with single quote ' that works fine to put in the string, but the command shell executing the command ignores these. So it has to be double quote "
I have tried all methods I have fount on the Internet, for example to have a backslash before the double quote and to have three double quotes, but nothing seems to work. I get a compiler error as below.
Error 4 Compiler error(s) encountered processing expression "String.Format("a -bd -y -tzip "{0}" '{1}*' -r", Path.Combine(BinariesDirectory, "output.zip"), BinariesDirectory)".Comma, ')', or a valid expression continuation expected.

How would I do a replace to replace a double quote with a blank space
What would I put in the ( ):
NameValueArgs.Item(i).ToString().Replace( )
I noticed that if I leave off the terminating double quote for a string constant in Visual Studio 2010, there is no error or even a warning, i.e.
Dim foo as String = "hi
However, the continuous integration tool we are using flags an error:
error BC30648: String constants must end with a double quote.
Is there some language rule in VB.Net that makes a terminating double quote optional "sometimes"? Is there some setting in Visual Studio that will make it flag this as an error, so I can avoid "breaking the build" in this way?

I do not necessarily wish to define the split to interpret double space as separator as I do not know whether this is always the case. I would rather like to tell the program that there are three double format numbers -> go and parse.

View 1 RepliesI have a DGV with a column bound to a Double. When I enter "1%" I get:
System.FormatException: Input string was not in a correct format.
I then try: MsgBox(System.Double.Parse("1%")) and get essentially the same error. (same for "$")
Is there a setting that will allow "$" & "%" as not only valid Double input but also do the correct adjustment for "%"?
I have a htpc project that I am working on. The main program loads dll plugins which are basically other win forms. On each of these forms, including the main program, I use a picturebox (a double buffered picturebox) for the background image and then draw everything on it by hand. Whenever I load the form from the dll and show it, I get a weird flicker. It looks like it is the previously used double buffer. Is there any way to clear the background double buffer before the flicker? Or am I going in the wrong direction?

I am new to creating websites for people on a money-earning basis.. I created my Dads website for my final year project, and he will pay me eventually but obviously I cant charge him as much as anyone else.I have just been to a trade show where I picked up 1 definite and 2 possible sites to do. The definite one is as follows:They want a site which:Has a catalogue for the customer to view, as well as being able to order products at a retail price.Has an administrative section with order tracking, catalogue management and page view stats.Has other basic pages such as Contact Us, Terms etc (all the usual).Enables customers to post comments about items, as well as manage their accounts (addresses, payment details etc).Is linked up to sage pay or paypal (or something similar).My task is to design this site from scratch and launch it for them. They already have the hosting sorted out, so no need to worry about that in the quote. I am planning on using .net and SQL Server, if this makes any difference.Basically what I would like is to get some quotes for what other people would charge if they were given the task.

I have this block of code that sets up my sql parameters for a stored proc that does an insert.
Dim sproc As StoredProcedure = New StoredProcedure("UsersInsert2", DataAccessConfiguration)
sproc.AddInput("@ID", SqlDbType.NVarChar, 10, entity.UserId)
sproc.AddInput("@PCode", SqlDbType.SmallInt, entity.PriviledgeCode)
sproc.AddInput("@Pwd", SqlDbType.NVarChar, 10, entity.Password.ToString())
[code]...
I've tested the stored proc in SSMS and it works.The problem is when I try to call it from the application. it fails. the @@rowcount = -1. I've tried returning an error code from the db... no dice. keeps coming back as -1 what is going to get executed looks like this
sproc = {EXEC UsersInsert2 @ID=ruxtest7, @PCode=0, @Pwd=1234, @Lang=E, @Name=ruxpint, @Notice=1, @CreatedBy=ruxpint}
I've re-used this code several times. only difference being I'm using NVarChar and it's vb.net.
