Some time ago in VB6, I wrote a recipe program that basically stores all the recipes as text files. I was going to rewrite it in .NET and use an Access DB. I figured this would help in searching and other things, ratings, etc. But I'm a little stuck. I don't know if:
a) I can or should store all the text files in the DB
b) convert the text files to some other file format
I can already use GetFiles with a mask to search the filenames, not sure if I need or want full text search. So, should I flush the DB idea or how to move forward? I really don't want to use SQL, but if that's the way to go then...
I'm doing a project where we are re-creating a very old system.The client wants the same base functionality and some improvements.One of the things I'm currently working on is the note-system. These are used as flags of some sort, but are also used as a comment field for some products or client profiles.In the old system you could write the text and save it like you would get in a .txt file. They want the new one to be able to do word formatting such as:
Different font sizes (Only some parts of the text) Different font colours (Only some parts of the text) Underlining of words Bolding Italics Tab-spaces
Those are the specs they want. What I need to know is the following:
1) How do I do that?
2) Currently they store all these files on the server as text files and the database have paths that refers to each file. I want to be able to save a text file with that formatting to the HDD of the server like in the old system.
3) If possible I would like to save that text to the database with the formatting.
I need to scan either a drive are folder and search for .theme .VStyle and shellstyle.dll and there folder/subfolder names.The code scans for all .Theme files on the drive or in a folder, when it finds it it stores the folder name that file is in and also the name of the .theme .
i know that integer is a variable to store whole numbers and that a string is a varialbe used to store any text, but what variable type would you use to store a number that has decimals?
To improve performance, when one has many files to readwrite it is better to save them in smallergroup in different folders. Is there a magic number over which it is better to start splitting the folder? for example below "10.000" (invented number) files can be stored in one single folder, while above that it is better to start storing files in multiple folders.
I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Me.Close() End Sub
I'm trying to store all my files into one file. I have quote huge file but the file stops at 194,000 KB and it doesn't save beyond that but the problem I've built says that the file has been saved. I would like to know if there is a way to go beyond this limit? And for the file to just keep getting bigger.
I'm writing an application that will be used to generate reports from a database and I want to have several predefined reports/queries built in but also offer the user the option to create their own query and be able to save it and run it whenever they want without having to set the query up again each time.
So I figured I would just store the query parameters in an XML file for the ones that a user has created themselves and I would store these XML files (one for each query) in the user's Application Data folder.
I'm wondering what I should do with the built in queries though (bear in mind that the parameters of these built in queries should not be configurable). As I see it, these are my options:
1. Have the query parameters hard coded in the application 2. Store the query parameters in XML files in the location where the app is stored (ie Program Files) - the installer would create these files when the app is installed 3. Store the query parameters in XML files in the user's Application Data folder with any queries they have created themselves.
I'm leaning towards option 2 for the following reasons: All queries (user defined or predefined) would then be in the exact same format and the program could then run them all in the exact same way. Option 1 would mean I would have to release a new version of the application if I ever wanted to change these parameters. Option 3 would mean that the program would have to create the XML files each time it was launched by a new user so it would be a bit pointless and the values for the parameters would still have to be hard coded in the application so that it could create the files correctly.
I want to store large files(over 100mb) in a sqlite database. I noticed, that its not good in performance.Do I have to store the files in a local folder, or do i have to rewrite my code?
Shared Sub BlobToFile(ByVal Blob As Byte(), ByVal file As String) Dim MyData() As Byte = Blob Dim K As Long[code].....
I'm writing a program that reads randomized test questions from a text file. The text file includes information about how to set up the screen including which pictures, videos or buttons etc. to show for each question. The user responds to the questions and another text file is created logging the results. would it be better to read in all the data from the text file into an array to work with during the test, or should I just read the questions one at a time keeping the text file open while the user responds. The amount of data that would be read into an array for an average test would be about 200 lines which range from a single character to 20 sentences (whose length would of course vary).
I have an ASP.NET application (vb.net codebehind) that has serious performance problems because of its storage of TIFF files in one server share. There are over a million .TIF files there now! The application tracks the scanned images of property with a corresponding row in an Oracle database table. We have this idea that it might be better to store the images themselves in a new Oracle table.
The alternative solution we are thinking of is to split up the server share into multiple folders by State (an OH folder, a WV folder, a VA folder, etc.) Seems like the database option might make more sense long-term, but how do we do it? Can a TIFF be stored in a BLOB column and then extracted back into TIFF format using .NET?
As I'm working with some image files for my project, where should I store it ?I mean, they will be displayed frequently to the user. What I do currently is store in the app directory and when needed, I use:
For some background images, I used to set it at design time. That is, selecting the image needed using the Image property and never changes it at runtime.So, what will be best place to store it efficiently.
Im designing a program that will read from various text files (preferably RTF files) and then put them into the RTF box in the program when a button is clicked.
Here is the portion of my code that i am referring to.
Try Dim fileText As String = My.Computer.FileSystem.ReadAllText("c:\" & selectedHero & ".rtf")
Catch MsgBox("Selected Hero currently has no File with us.") End Try
Now heres the problem. In the file i have a few pictures and its formatted and what not. I thought since its a RTF file and the Box is RTF it would auto format.... but anyways. It appears like this in the RTF Box.
On a image file (PDF), the OCR has recognised the picture and text. However on Visual Basics, how do you search for a text on this image file? The primary goal is to allow a text search (i.e POxxxxx) on all the image files (PDFs). The returns of the search will be the assciated image files where the text (i.e POxxxxx) is found on.
I want to create an application which acts like a file cabinet, where in i can store all my files viz. xls,doc,msg. So that i do not have to look for my files in hard drive, i can open an application and retrieve it from there.My application will be a standalone application whose data is stored on the location i mention in the application.Is it possible to build an application like this.
We're making a project named personal digital library. It works like an automatic file organizer, which organizes files accdg to different topics, which falls under document categorization. The problem is we don't know what algorithm will be used in our project, we're using VB.NET 2008. Another is do we need to create a database to store the files to be organized?
how i need to store data to the program files directory, but i couldnt becuase it required adminstrator privileges. After searching around i found an appdata folder with the path "C:UsersCristian RiveraAppDataLocalVirtualStoreProgram

how to download folders and i know how to search for folders but how can i download a folder into the above directories without knowing the name of the user account.
I have created an updater for our clients application. The way the updater works is to download all the updated files and store them in a temporary folder then check the file hashes. If everything is ok it will copy the files to the applications installation folder. Once this is been completed it will delete all the updated files in the temporary directory.
My problem: I am looking for a directory that will be available for XP, Vista, and Win7. I was thinking about the 'temp' directory.

I'm trying to store and retrieve PDF files using SQL server 2008 and Visual Basic 2010.The Issue:i need to lookup a PDF file and store it to the DB using filestream and display it in Adobe Acrobat COM Control on VB Form?
Is it possible to store excel, word, pdf, .rar .zip files to a column in a table of a SQL Server 2005 DB.And also open the fie with excel, word, acrobat reader, etc????My other sollution would be to store the file on a location on a server and only sory the filename and location in my db and then open them with "Process.Start("filename")".My main problem with solution 2 is this:Lets say I install the programm on a pc called "manager". When I use the savefiledialog and I am on the manager pc the string C:/myfiles/test.xls will be stored
I have a process that's going to initially generate 3-4 million PDF files, and continue at the rate of 80K/day. They'll be pretty small (50K) each, but what I'm worried about is how to manage the total mass of files I'm generating for easy lookup. Some details:
I'll have some other steps to run once a file have been generated, and there will be a few servers participating, so I'll need to watch for files as they're generated.Once generated, the files will be available though a lookup process I've written. Essentially, I'll need to pull them based on an order number, which is unique per file.At any time, an existing order number may be resubmitted, and the generated file will need to overwrite the original copy.
Originally, I had planned to write these files all to a single directory on a NAS, but I realize this might not be a good idea, since there are millions of them and Windows might not handle a million-file-lookup very gracefully. I'm looking for some advice:
Is a single folder okay? The files will never be listed - they'll only be retrieved using a System.IO.File with a filename I've already determined.If I do a folder, can I watch for new files with a System.IO.DirectoryWatcher, even with that many files, or will it start to become sluggish with that many files?Should they be stored as BLOBs in a SQL Server database instead? Since I'll need to retrieve them by a reference value, maybe this makes more sense.
How can i store unlimited multi-row strings without the need of extra files?Example: the user enter a multi-row string into a textbox and clicks save. Then the program should save that somewhere. And then the user enters another string and clicks save. And then there is a combobox where it can choose between those 2 strings to load.Can i save them in some sort of collection like My.Settings.Collection? Where each text also has a header.

I Need to Store bunch of Jpeg files from local file system to a column with image datatype in databse.Can any one please provide me some code to do it?
i have an old VB6 system that generates plain text files. When this old system writes "A" into the file, it writes (hex) "41". For an "ä" (a-umlaut, special gernam character), it writes (hex) "E4".
Now i have to process files like this in VB.Net. when i open such a file in the IDE, it displays correctly "ä" (But not always!). To see what i mean, please open a notepad and create a new file "ae.txt" with content: äöü. Now your file contains exactly 3 bytes: (hex) E4 F6 FC.
But when i write code like Dim strTest As String strTest = File.ReadAllText("ae.txt") Debug.Print(InStr(strTest, "ä"))
i get 0 - so i cannot find back the "ä" - what do i need to do, to find it? And 2) for compatibility reasons, i have also to be able to create such files. How to do that? Seems the different encoding types do not work as i think.
I am trying to create a program which will read the files that exist in a directory, and then write in a text file the specific information (full file name, date created)i have found several code in the site but i cant make it work, the machine i am running the code is XP and i am using VB2008.The code i have found is the following:
