VS 2010 How To Store Unlimited Multi-row Strings Without Need Of Extra Files
Dec 9, 2009
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.

So my program works off a few templates in a folder called "Templates".So far, i have been deploying my program as though it would run from a CD. Deleting the autorun file, inserting the Templates folder myself, and then using a self extracting ZIP to make it easy for the user to install.While this works, i would like to make it easier on myself by just including the Templates folder and the two template files (both .xls files) in the program every time i deploy.I've tried dragging and dropping the folder + files into my solution explorer bin folder but it doesn't work.I'm using Visual Basic 2010 Express.

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:
vb.net
PictureBox1.Image=New Bitmap(Application.StartupPath & "ImageName.png"
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.

First it might sound like an ordinary task but keep reading it isn't. I can't figure out how to find a phrase in a text file, and replace it with something else. Tried lots of things but always ending up with empty hands.
Suppose there's a text file in this order:
valueabc=6000.0000
valuettt=200.0000
valuexyz=7000.0000
I want to;
1) Find the phrase (e.g. valueabc) by scanning the whole text,
2) Replace the number that starts after "=" and ends before ".", namely "6000" in the middle with any number value i want.
I don't need the parts before "=" and after ".", only the number in the middle.

Does Anyone know How to read multi-line strings? I am using XmlWriter to write a Multi-Line Textbox to an Xml Document. The Trouble Is I can't figure out how to get the reader to read that multi-line element. I know the writer is writing it in multi-line, but the read just squashes the lines together. Does anyone know how to read that multi-line element properly?

I'm concatenating data files, but the problem is that I'm seeing some extra bytes where the files are joined. The new file has extra bytes. I had thought this was maybe a problem with encoding.Here are the methods that I've tried to use to concatenate the files. The first example I'm getting extra 0xA0 0x00 bytes.
Dim inputfiles() As String = Directory.GetFiles(sourcedir, pattern)
Dim bufSize As Integer = 1024 * 64
Dim buf As Byte() = New Byte(bufSize) {}

I created a simple BMI calculator through the guide.I have built it and published it on my laptop running Vista Home Premium with .net 3.5 SP1 installed.I can run the setup and subsequent exe file fine on my machine but when I try it on my girlfriends netbook (one of those fiddly little things) it wont install saying that some of the files are missing. It is running XP and also has .net 3.5 SP1 on it.There are only 2 extra files in addidtion to the setup.exe that vb 2008 creates and they are the application manifest and the program icon, both of which are located with the setup.exe but it still won't install. It is an offline installation but won't run.I copied the bin folder from the project to the setup folder and tried that, still no joy, yet if I try and run the actual program directly it works?

For my website I've just implemented tinyMCE for my site (just a word processor). Everything works fine except when i try to store the string variable input into a sql server database. I want to store a string and not have the html tags make me exceed the 8000 length limit(the html tags take up most of that space). My question is, is there a solution so I can store my document with the html tags without shortening my document? Create an if statement that will determine the length If > 8000 than split the string apart and insert into separate fields. Maybe their is a compression feature which I'm unaware of?

In the past I've used a Singleton Pattern to load the connection string when the application starts via the global.asa file.
I have a project now where each user has a unique connection string to the database. I would like to load this connection string once. The issue is that the singleton pattern will not work for me since each user has there own connection string. Basically the connection string is created dynamically.
I do not want to store it is session. If anyway has a clever way of doing this in .NET let me know ?

In .NET which data type do you use to store list of strings ?Currently I'm using List(Of String) because it's easier than Array to manage and add/remove stuff. I'm trying to understand what are the other options, when they become handy and when I should avoid List(Of String) usage.

I'm just getting started with Visual Studio (2005), and my aim is to write a fairly simple application in Visual Basic that will need to store some data to disk.What I really want is to be able to send the application to the end users (xp, vista, win7) and have them just be able to use it without having down download all kinds of extras. For example I'm guessing that if I use an SQL database in my application they will need to download SQl server express or some other sql downloadable?
If so is there a similar downloadable for MS Access?I'm just in the 'seeing how things work' stage at the moment and I don't want to waste time going down the SQL track just to find it won't actually work unless my users all download SQL to their machines (which they won't want to do).

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'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.

1. I get an empty page at the end of a report. I have 4 pages instead of 3, 8 instead of 7 and so on. I see and print these empty pages. The report width less than the page width minus margins, so this cannot be the reason of my problem. How can I get rid of these pages?
2. If I have a few controls ReportViewer then to print the report I must to press each print button on each ReportViewer, and each ReportViewer prints with a new page. Have I possibility to print all the ReportViewers consequently pressing one button and to continue the report?

I wrote a small API gui to communicate over foundation fieldbus.I've used a While loop that constantly reads some parameter values from the bus. At the end of the While loop, I put Application.DoEvents()so that I can use another button to stop the reading process. It all seems good and easy.. but there's one problem: when I get the While loop running and wish to stop the process, I have to first click somewhere on the form, anywhere, before I could click any buttons(either 'stop reading' or 'reset' button mostly). That extra click makes my form seem unresponsive and lame.I wonder whether this is a problem pertaining to DoEvents() or my use of Foundation fieldbus.

I have an rdlc report that always produces the last page in blank. In this page, the header and the footer are printed but no data is shown (all data finishes in the previous page). I already checked and re-checked the horizontal and vertical printable areas and all the report definitions fit into these areas (if not, a blank page will be produced in between each page, I guess). If the report has one page, two pages are printed, if there are ten pages with data, eleven pages are printed
