Visual Studio 2008 - Split When A Character Is Found ( Txt Not Delimited)
Apr 15, 2011
I am trying to populate a datagrid from a .txt file. I managed to do it with the split function Split(sr.ReadLine, " ") when I have all the rows identical with only one space, but the problem I have is that the txt file is not delimited and the "spaces" varies some time. This is a sample of my data:
Col1 Col2 Col3
1 Mary Yes
1234 John Yes
999 Leo No
So my question is how to delimit or split the line based when it finds the next character and ignore the empty spaces. This is the code I have.
are loaded in listbox1 and i split the "," and its value to textbox1 when i select the index 1 in listbox i get the same value as first index here is my code for load the textfile to listbox
Dim linereader As New System.IO.StreamReader(OpenFileDialog.FileName) While (linereader.Peek <> -1) ListBox1.Items.Add(linereader.ReadLine.Split(",")(0)) End While
Will i be able to successfully install 2010 beta 2 side by side 2008? because i want to test 2010 features and some development toolkits such as silverlight while i don't want to uninstall my visual studio 2008 professional.
I have a Visual Basic project and when working and modifying code, the compiler will crash and then a message will say something like "Microsoft visual studio encountered a problem and was shut down." I've tried editing code from the solution and the project. Both produce the error. Usually occurs when adding an "IF...Then..." condition. May work for hours but then crash. Solution will compile and build.
I have spent a long time debugging an application that occasionally goes awry, it ends up that the problem is that the comma delimited text files that I am looping through occasionally inserts a comma within one of the fields.
At any rate, I was loading the text file into Excel to try and spot the error which was of no help, somehow Excel parsed out the field correctly and didn't use that extra comma as a delimiter. Is there any way I can get my application to do the same?
And example field value is: "7-8-ALL (1,2&3)", but of course my split code turns this into two separate array values.
In a while loop, I am writing a progressively increasing integer value (between 0 and 100) to the Value attribute of a ProgressBar control, when it disappears from the window in which it resides. I have verified at the time that it disappears that the Min is 0, Max is 100, and Value is a valid integer in range.
How do I disable the background compiler for Visual Basic in Visual Studio 2008?
For my sins, I have to work on a large VB.NET project and it often locks up for 20 seconds at a time whilst doing the very helpful background compilation
I'd rather work blind between compiles and be able to do some work.
I am trying to make a console program in Visual Basic on Visual Studio 2008. I want to ask the user of the program if he wants the premium version or the standard version. If he chooses the premium version, then I want it to say premium in his "receipt" later on and if he chooses standard, then standard in the receipt.
I have Visual Studio 2008 Professional and I'm trying to make it so I can click a button to send the application to the System Tray and then click the icon in the System Tray to make the application come back.
Can anyone provide me a method or sample code to do this?
I am very new to Visual Studio Application Development. I'm mostly a DB guy. I used Visual Studio as a Report Designer, not much of an .Net guy though I can understand it. I am now asked to create a .net application and I'm trying to create a "Hello World" starter app. I opened my Visual Studio, click File-New Project and all I see is Business Intelligence Projects and Other Project Types. My step-by-step guide says choose Visual Basic, Windows Forms Application. But I can't see it as an option.
I recently loaded my copy of MS Visual Studio 2008 Standard Edition, with Visual Basic, on to my new laptop, one with a Windows 7 operating system. This version of Visual Studio had been on my other laptop, a Windows Vista machine. When I attempt to run any of my Visual Basic applications which has a MSFlexGrid container on it, I get this error message "Unhandled exception has occurred in your application... The error is: Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG). Also,
whilst trying to debug a sample program, get error code bc 32400. Also error code Class 'CLSID_CorSymWriter' could not be created system error &H80040154&
WebMatrix is a web development and deployment tool by Microsoft so how is this compared to Visual Studio? which Use C# Razor Syntax is that more better coding.
I have been working on a game development program for a few days now. And have come to a halt on one part, and thats adding a 3D space in the program. I do not know the code for this, would some one please provide something i could use for adding 3D space in my project? for example, i have a panel set up to be the view port in to the 3D space. Now i need to figure out how to program it so you can see a 3D space, click on the mouse and drag and the grid will follow the mouse.Likecreate a grid, i wish to give it a grid of 150 x 150 grid pixles.
I have to compile projects which was compiled in Visual Studio 6 in Visual Studio 2005. When i compiled i got a set of same error. I opened the project for VS6 by selecting File->open->project/solution and tried to build a solution by Build option but i am getting the following error.
I have to develop an application using MS Visual Studio 2005 or above with the following objective:
* The application should allow users to create as many new forms as they want and each form should behave like a MS Visual Studio WinForm. By saying that it should be a container for drag and drop of controls from the toolbox that I will develop....
* Once the user design's each screen to his taste by placing various controls on the form, he should be able to save the form as a screen. Of course I have to provide functionality for each of the controls such as if he drags a button on to the form, he should be able to specify what action it has to perfom when clicked when the application is put into run mode. Quite similar to regular windows form button.
* My application should have two modes: a DESIGN MODE, where user can drag, drop controls and specify what they should do when put into RUN MODE. This is quite similar to MS Visual Studio designer.
* Last but not least is to be able to access the application via the browser with the same look and feel his desktop version.

I'm trying to split a Yahoo historical stock price csv file, downloaded into a string, by what looks like a space character. I want a new row for each split. The split function works for other characters I see in the string. I suspect the characters may be a non breaking space character but I've been unable to split on them. This is the test csv file that is downloaded into the string: [URL] I'm trying to split the string like this:
i am using the Webclient and Streamreader in Visual basic 2008 to retrieve data from the web. I access Yahoo and download stock information this all works well except for one area. All the indices symbols on Yahoo start with a circumflex character ^ so for example, the Dow Jones Index code is ^FTSE. When I include the ^ in the URI string sent via the Webclient it does not send the ^ it sends the code for ^ instead which Yahoo sees as %5E. Having made some tests is seems that certain characters do not get converted to their hex code and some do. A * gets sent just fine but a % also gets sent as its code 25.If I manually enter this from my browser it works just fine.
How can I "Split" a string in every 2 character? What is the fastes and easiest way to do it? (every string is 12 characters) exampel: 123456789011 I want it to be 12-34-56-78-90-11.
When I am looking at code examples sometimes they are in .vbp Now I know that is vor visual basic (.vbp) But How do I edit it in Visual Studio 2008. Should I use Microsoft Office's Version of Visual Basic?
I have had to do other things in life but recently I have been able to return to my project of getting a FFT for images using Visual Basic.I found that there are several things that can slow it down and as such I have found ways to greatly speed up the DFT without the further
step of using a Radix2 method. I will try to implement the Mod twiddle/twaddle later.But first I found that I can use just cos terms or just sin terms without having to use both.First I found that I can create all the analysing frequencies and their Cosines angles with the following code.The addition of (PI/4) allows the use of only the cosine terms( or only sine terms).The first part of the code test for the size of the rows of the picture and if not an even multiple of two it resizes the image so that the number of pixels is an even power of two. I dont care if the number of rows in the picture is or is not an even multiple of two at this point.
i'm running Visual Basic 2008 Express Edition (latest service pack ... 9.0.30729.1 SP) on XP Pro SP3 with .Net Framework version 3.5 SP1 I have a rather large project I've imported from Visual Studio 2003 (Standard).The project compiles and runs just fine ... my compiled program itself never crashes.
But while I actually have the code up in the IDE, and simply adding/deleting code the whole IDE will randomly crash (usually without warning) and I loose my changes since last save.If/when I do get some hint of why it crashed, I get a window about illegal whitespace or something.... but that's rare ... usually it just crashes without warning and the whole IDE completely shuts down instantly. just deleting/adding a character is enough to trigger it maybe once every 30 minutes.
This is on a computer that is otherwise very rock solid .... no other program ever crashes, etc.
I need to read this data into a string array. In my new file I need to write Name,Sal and Location columns only. Here is my code:
Dim ioReader As New System.IO.Streamreader("C:old.csv") ioLines="Name,Sal,Location" Dim ioWriter As New System.IO.StreamWriter("C:
[Code]....
When I am splitting the above data, the sal column values which already contains "," is splitting into 2 cells. I want to keep the sal column value as a single cell by ignoring "," in between numbers.
