VS 2008 Reading A Custom File Format?
Oct 20, 2009
The file format has already been explained to me, and I can easily view it in notepad to understand it. It's basically a text file with a fancy extension and what not. The only problem is that I need to read it and pull a certain span of data from it.Here's the basic format:
8200
3251
1
[code].....
This is the first 10 lines, which is useless data for me. However, right after the first 10 lines, is a span of an unknown quantity of lines that I do need that are formatted like so:grassC:Program FilesMicrosoft GamesHalo Custom itiondatalevelsestlood_creekitmapslood_creek groundThe first line is the name of a bitmap assigned to the ID, while the second line is the path to the bitmap.Finally, after the unknown span of lines, there are two lines that go in this order:01Which I can safely assume at this point that the list no longer needs to be read.What I need to do is be able to open this file, skip over the first 10 lines which are completely useless, and then pull out the unknown gap of lines, and then stop reading when the line is '0', or at the end of the list.

OK, for those that saw my previous one, this one is different than that, much different.The program I'm making is basically an offline, open source Po, which will allow for people to create their own Databases of Pon, even custom ones, without any hex editing as long as they use the program to create the files. developing a custom format for my program, the ".pid" format, which stands for "Pokex Information Data-File". Yes, I know it's for Poon, but it's a program I promised to end with, and I'm also kinda doing this for myself (Still being a fan of the game series.)w, the file format is done something like this:

I'm trying to build an app that will read custom properties set in an accdb file. Basically, I'm trying to build a Front End updater (Yes I know there are others already built, but they don't work the way I want). The Custom properties are initially set manually by pressing the Office button, going to Manage, then Database Properties and selecting the Custom tab.
I've got most of the code set up, but my sticking point is how to read the custom properties.
Following is the function I use within Access VBA to get the properties, but obviously this is not going to work in VB.Net.
[Code].....
I think I need to replace one or more of the 4 lines after the On Error (yes I know I need to change the Error trapping too). I'm guessing I need to connect to the database file (an accdb, btw) and then go from there to define the container and documents collections.

I came across this great article on creating a custom datagridview column which creates a graph-like effect in the cells of a custom datagridview column:[URL]..Does anyone know how you would edit this to format the number in the cell as a percentage? And does anyone know how you would set this up to take 0 values which do not create any graph effects at all.I have been trying to do this but keep getting errors.

The bottom line on a dropped-down datetimepicker shows the date different then in the text-part.In my case, the text-part format was yyyy/mm/dd, but the bottom part of the dropped down part stated Today: dd/mm/yyyy, what is probably the format set in the regional settings.

I want to format the Timespan to have format like this 49 hr 34 mn 20 sec
I used the String format below :
String.Format("{0:00}:{1:00}:{2:00}", theTimeSpan.TotalHours, theTimeSpan.Minutes, theTimeSpan.Seconds)
It formats the Timespan to this format 49:34:20. How can I add hr mn sec to the String.Format above? or there's another easy way?

I created a new cursor (it works properly, I tried it in windows 7) but is not working for me in the program.I took the Windows cursor (aero_helpsel_xl, from C:WindowsCursors) and it appears to me the same error.i use with this code:
Me.Cursor = New Cursor("Patch..")
The problem say:: "{"Image format is not valid. Image file may be corrupted.
Parameter name: stream "}"
edit: I realized what the problem ... It can read only cur files with 24-bit color and lower - but it shows only two colors: black and white.

I'm new to Visual Basic. I'm trying to get this code to read a .txt file line by line. If the only thing that the line says is "B" it should add one to the intTotalBoys integer and so on with G for Girls, F for Fathers, and M for Mothers. I'm not sure why it won't work. [code]

I need to read in each line of a file that is comma delimited and I know how to do this.ut for this file, some of the values have quotes around them that contain commas and others do not. For example, the name field has "Doe, John and Lisa" and the other fields do not. How will this be handled? Will it read that whole field in as one or will it still seperate it as seperate fields?

What is the right way to use a custom format string on .e.g a zip code?
The zip code in the database might have 9 characters, but the program should only output five. Using string.format("{0:#####}","322318825") will output "322318825", the entire 9-digit code.
Zip codes are only an example. This is actually for a dynamic format function that takes two arguments, one is the format and the other is a database field value. Therefore, it cannot work by being strongly typed.

Code:TimeTo_dtp.CustomFormat = "dd/MM/yyyy - HH:mm:ss"This works fine, but what I also want is for the the user to be able to select their time more precisely using miliseconds. After searching around I came across this web page:It has all the different formats on there. If you scroll down you will see format 'f' then format 'ff' then format 'fff', 'ffff', 'fffff', 'ffffff', 'fffffff.'What I am asking is how do I use that in my example?
I tried
Code:
TimeTo_dtp.CustomFormat = "dd/MM/yyyy - HH:mm:ss.fff"

I have several quesions about reading/writing structures from/to files.In a scenario when I open a data file having its own header and variable data fields I create a structure that represents a header consisting of 9 bytes:
Public Structure HeaderInfo
Public DataField1 As Integer
Public DataField2 As Byte
Public DateField3 As Integer
End Structure
I'm using this code for the time being:
vb.net
Public Function ReadHeader(ByVal FileName As String) As HeaderInfo Dim ReturnInfo As HeaderInfo Try Using br As New IO.BinaryReader(New IO.FileStream(FileName, IO.FileMode.Open, IO.FileAccess.Read, IO.FileShare.Read)) With ReturnInfo
[code]....
The first question is - can I fill the structure directly somehow? Some structures are very long and filling them this way will be tedious. For example, if I know the length of the structure I could read the needed number of bytes in a byte array and somehow marshal these bytes into the structure.I can use Marshal.PtrToStructure, but then I would need to get an IntPtr of my byte array. I use <Serializable()> attribute for my structure.

Ok so there is an XML file for a program that already exists that stores a list of files along with other information.I need to open this file and read the file names and then potentially add files to it if they DO NOT already exist in the file.It is very important that I not wipe the XML file and have to write it from scratch every time.
