C# - File Header Comment At The Start Of Every Human-created Code File?
Mar 11, 2011I'm going through All-In-One Code Framework Coding Standards document and one of the recommendations is to add a file header comment at the start of every human-created code file. This is the first time I've seen such a recommendation and to me it's just an unnecessary and ugly clutter but I'm wondering if someone could explain why M$ recommends this?

Page Header Of An Excel Spreadsheet - Using Header Text As Tab Name
Oct 21, 2009I'm using the following code to populate a DataGridView with a worksheet. This is working fine, however, I'm unsure how I can get the Text from the page header. (not to be confused with the column header). Later in my code when I am exporting into an existing workbook with a new worksheet, I'm wanting to use the header text as the tab name. The header text being "September 2009" so that when I import/manipulate/export october, the new tab will be "October 2009" etc. [Code]
View 1 RepliesFile I/O And Registry :: Binary Reader For File Header?
Oct 23, 2011however, I am stuck at BinaryReader.actually this is what i am trying to acheive through VB.NET.say for the following file type :
JPG file = FF D8 FF E0
BMP file = 42 4D BE 4E
PNG file = 89 50 4E 47
GIF file = 47 49 46 38
the above are the 4-byte headers in Hex(raw) I need to read these headers of any given file using OpenFileDialog using Button1_click event,on selection of any given file(*.* filters ON)it should use the BinaryReader and look for only 4-bytes starting from offset 0, and it should not go to EOF marker (-1).and have a variable to hold this 4-byte header value, to run this in a database table which will check the same header value in the table and would display the corresponding extension of the file. from the table.
I can do this using case, if then...etc.however, I have to do it using Database and also i need to check for testing purpose to use MsgBox() to display this variable which is holding the 4-byte header.however, the MsgBox doesnt allow anything other than String.
PS: I tried studying the methods like:
FileOpen/Seek/Peek/ReadBytes().
but still not sure how to get them work.

I have to verify whether column names are in order, if not i have to produce a error. I have to use a script task for this one.

View 1 RepliesGet AVI Header Info Without Playing File?
Mar 18, 2010I have been working off and on for a year on my own media browser that I created in VB.NET. My program will play MP3 playlists as well as supporting drag and drop
Getting fileinfo of an mp3 is no problem but I have discovered that it is more complex when I try to get file duration of video files (.avi,.mpg) etc.
My code listed below uses a timer. In order for me to get a video duration value, I must actually play the file in axwindowsmediaplayer1 for one second. This seems not practical.
I have seen many examples on the internet in C# that read video metadata without need to play/load the file. Why are there no examples in vb.net of this? Is it too difficult to achieve in vb.net?[code]...

C# - Nlog - Generating Header Section For A Log File?
Nov 16, 2010Just recently got into experimenting with NLog, and it occurs to me that I would like to be able to add header information to the top a log file such as:
Executable name
File version
Release Date
Windows User ID
etc...
After some searching I have been unable to find anything in the existing on-line documentation or code forums which indicates this type of functionality. Is this possible? I have always previously included this sort of information in log files, and have found it useful on numerous occsions in the past, when sourcing information on production issues at customer sites. Admittedly, this functionality was custom built for the solutions and not based on any of the current .NET logging frameworks.

How To Create Header File Containing Class Functions
Mar 6, 2010I'm wondering how I can go about creating something like a header file to contain some verbose functions I don't want to have to look at after I get them created. Something like in c++ like..

Magic Numbers - File Header And Footer
Feb 12, 2011For my project, I need to develop an app, which will have MS-SQL db with 4 tables
a>FileHeader
b>FileFooter
c>Extension
d>Detail about the file.
This is all to do with the Magic Numbers, or File header and footer, found in all files. The first 4-byte and last 4-bytes.
Example:
Suppose a word DOC file when read using this app should return and match the values
D0 CF 11 E0
So, how can I read the files using vb.net, fileIO, FileStream/StreamClass/FileReader? I just need to open the file and read the first 4 and last 4 bytes of any given file. And then it should connect back to the SQL database and lookup for the matching values from the tables as I had mentioned. And return a match found or not found.

View 1 RepliesSort Of "header File" Or "dll References File" For .Net Languages?
Mar 6, 2009I'm making a small scripting engine in C# and I was wondering, is there some sort of #compiler directives or some sort of other header-like file I can compile with my script files to define what Managed Dlls my script files are referencing?
[Code]...
I would love to be able to eliminate this line of code:Parameters.ReferencedAssemblies.AddRange(References);and put that information in my scripts instead. The problem is I do not necessarily know ahead of time what .dlls the scripts are going to reference. My current solution right now is to parse a custom "script.cs.refs" file that looks something like this:"System.dll","System.Data.dll","SomeOther.dll","Ect.dll" where visual studio stores your references to dlls and if it has to be defined in a separate file, if there is a standardized format I should be using that I can load into the compiler that tells it this information,
File I/O And Registry :: AVI Header - Program To Download And Play AVI Files The Files Are Large In Size And Long Time Wise
Dec 11, 2011I wrote a program to download and play AVI files the files are large in size and long time wise. I have the files playing as they are being downloaded but i can't see how long the file is or seek reliably. i was reading that the AVI headers are in the last 512kb of the AVI file *why would't they put it at the start* lol so my question is is there a way to download the last 512Kb of the file i'm downloading. i have the Bytes Read and Length of the file while its downlaoding i'm just not sure where to go from there, or how to do it atleast. If i had the length in time of the Avi file i could set the trackbar to be able to seek properly. or if someone has an idea how i could get the time of the video by using fps and some math i could prob do it that way too but idk how i would tell how i can find how many kb are in the fps i'm sure it changes so think that way is't going to be reliable. how to get the last 512kb would be the best option not sure if it can be done even.
View 4 RepliesRead The "FrameSize" From The Header Of A SWF File?
Feb 12, 2012I am trying to read the "FrameSize" from the header of a SWF file. I know it starts from the 9th byte and that it is 9 bytes long. I am getting stuck on the next part though... What I now need to do is read the first 5 bits of the FrameSize ByteArray in order to determine how many bits make up the remaining 4 sections of the tag. Then I need to read each of those sections to get the data I need.
I've been googling for ages and trying different things, but I am still clueless on howto grab the first 5 bits and turn them into a usable value that I can then use to navigate the remaining bits.

DataGridView - How To Set Row Header Value
Apr 22, 2010I have an application where a datagridview is used to display some data, a datatable is bounded to it, and I want to put some text in the front of some rows to indicate that they are different from others. My code checks the rows and used the following
mydatagridview.Rows.Item(iCnt).HeaderCell.Value = "A"
To set the row header values, it was fine when the data was first loaded. However, when I sort the datagridview by clicking the column header, these rowheadercell values disappear. How to keep the row header values after the sorting?

View 5 RepliesTab Header Flickering?
Dec 6, 2010I am working with GDI+ to draw backgrounds for my forms. I have a main form with 4 tabs, which all flicker. There is a gradient background behind them (bitmap drawn in GDI+ at Form_Load). I have double buffering enabled in the following manner:
Me.SetStyle(ControlStyles.UserPaint Or ControlStyles.AllPaintingInWmPaint Or ControlStyles.OptimizedDoubleBuffer Or ControlStyles.ResizeRedraw, True)
Everything on the form rarely flickers. The only times are when I am resizing, the numerous docked controls on my piece-o-junk netbook flicker momentarily, which is hardly noticeable. On a normal laptop it runs quite smoothly.The problem of which I speak is right on the headers of each tab (the white rectangle with text on it). When I move my cursor on or off of it, it will flicker. What is actually happening is that it is momentarily disappearing then re-appearing. This seems to be a control paint bug.I've tried the following override, without success.
