Reading A Text File In Separate Labels?
Dec 4, 2011So my issue is that I created program that writes a text file in several lines but I am having trouble reading those lines in separate labels on another program. I don't want them in one label but separated with one word to one label.
how can I put a counter on the time a new file is added to the program? I can't seem think of a code for it.
This is my coding so far but I feel like it's not really giving me anything

Reading Data From A CSV File?
Nov 24, 2009I am working in VB.NET 2003 and here is the issue of the day (for me):
I have an application which is supposed to read data from a CSV file one line at a time then pick out the 9th item ( a number) in the line and then add these numbers together for a total. The problem is the routine does not get beyond the first line. The code is as follows:
Dim total As Decimal = 0
Dim reader As StreamReader
Try

How do I get this routine to advance to the next line of the CSV file and continue to do so until it has read the last line?

Reading In Data From A Text File?
Dec 4, 2009Ive made a program that reads in data from a txt file that has 4 columns, but it doesnt work if there are headings to the columns or any other kind of text at the top of the file. I basically just want to be able to skip any text at the top of the file, either by the user specifying how many lines to skip, or by code that can calculate how many lines to skip.
At the moment, the code opens the file, calculates how many lines there are in the file, redims an array to this size, closes the file and then reopens it so its ready to have the data read.
This is how the data is input into the array at the moment:
ReDim data(lines, 3)
i = 0
While Not (EOF(1))
[Code]....
I was thinking a possibility would be to use a try statement so that if the data is a string, then it skips over that line, but i couldnt figure out how to put it together.
Reading Only Certain Data In A Text File
Mar 31, 2008I am currently trying to write a program that will do the following. 1. The user will open a .txt file that needs to be converted into a CSV file. 2. The user will then click on a button to convert the file. 3. The program will parse the .txt file for the necessary data and will then write the data to a new CSV file. So far I am sure that I can write the code which will open the file and which will save the file to the new format. Where I am having problems is with the .txt file format that I have to work with. [Code]
Each field is fixed length with the empty space in front of the starting numbers being a field. I have been unable to find any code that would show me how to parse only certain data from this .txt file. What I need it to end up looking like is this: [Code] The program itself needs to be pretty simple as the .txt file will only have at most 25 to 30 records. I was thinking of using a StreamReader to read the data into an array, but I can't figure out how to get just the data I need out of each record.

Reading And Writing Data To A Text File?
Sep 28, 2009The program that I am writing has three default variables that I would like it to store and also be able to change. I have them in a text file called "settings.txt" The format of the text file is as follows:
Default Source "I:DCIM101MSDCF"
Default Destination "C:Documents and SettingsChristyMy DocumentsMy Pictures"
Default Backup Destination "D:My DocumentsBackupMy Pictures"
The field descriptions eg "Default Source" take up 30 characters, so the variable data starts with character 30. I know their has to be an easy way just to pull out the data from a particular line starting with character 30 but I can't find it.

Reading Name And Numeric Data From Text File
Apr 27, 2012I'm working on a program for a side business I run with a friend, who is a non-programmer.I've done a program before, using IO.StreamReader and IO.StreamWriter to read and write lines to a text file.
But now, I'm working on reading text data (it's output from an old legacy program) that reads a first and last name, and the customer number (6 digits) from one file.
Then, it uses the data (customer number) read the first time to cross reference the zip code and status from a second file, and display it.
The Data in the Text Files are as follows:[code...]
How would I begin parsing for the first and last name, and the customer number to assign to different variables?In the line that references names.txt I meant to put customers.txt.
That's a snippet of code I took from a previous program, so I know how to read the data, just don't know how to extract it.
VS 2008 Reading BigEndian Data From A File?
Jul 28, 2009Is there a way to set BitConverter to produce Int32 values from BigEndian-encoded bytes?I feel like there might be a way to temporarily "set" the encoding to BigEndian before calling BitConverter, but I haven't figured it out.Right now I'm just reversing the 4 bytes before calling BitConverter, I guess I could create my own function that adds the bytes with the appropriate multiplier, but it seems a little inelegant if it can be done simply with BitConverter.

May 23, 2011Here's what i've got so far, i've written all of the data that i'm going to put into my config file, however i'm having trouble reading the specific string values that I need from that ini file. The parts of the ini lines I want to get are the values in between the I've tried using streamreader a couple things but i'm having trouble figuring that out. I need to parse each line of the ini file to get that value in between the single quotations, so that I can set the value for my richtextbox background and text color as well as a few other things that i've set up in my notepad including tab spacing and so on. lots of these different values need to be converted from a string value to integers, and boolean values as well. (4 of them, the rest of them don't have to be changed because they are already string values when my application reads them to determine it's application load settings.
EDIT: I just noticed in the preview that this is from the version of the app where I had streamwriter write "______ value=" & Something to a file. lol some of the (')s are still in this version, so please excuse that little part. I had them in, but took them out so that I could trim data to get a value easier, but I want to use (')s hopefully when all is said and done.For example, just to restate what I want - in the ini file it will read [setting name] value='VALUE'I want to be able to "get" the string value of "VALUE" within the ini file between the 2 single quotations '

VB Express 2008 - Reading File And Use Data And Average Them Out
Nov 29, 2009I have a text file that the first part of my program writes data to, but for this second section, I need to read that file and use pieces of that data and average them out. The text file is setup up with 90 lines of data starting with the first 9 lines containing data and the 10th is a blank space. I need to read line 6, 8, and 9. I need to Loop through the file so I am using the Do While Loop. Where I am confused is when using the For...Next Loop to tell the program to read a specific line. If you have any info that can lead me to the answer that would be great. I would prefer you just point me in the right direction because I would very much like to somewhat figure it out in the process.

Reading In Data From One Excel File Write That Data To A Different Excel File?
Sep 28, 2011I am reading in data from an excel file that is only viewed inside the program. This excel file is being populated by data from multiple PLCs (7) through DDE links via RS Linx Gateway. I would like this data to be written to two different excel files and specific sheets within those so that it can be viewed later on.
My program has a form that will allow the user to view the data live, meaning they look at the first excel file from the program so that they are not able to edit the DDE links or change the file in any way. The other excel files (there will be two, one for good parts, one for bad parts) have specific sheets for each part and each tester station. For example, if the part is a ABC part, and it is a good part, and it was tester on tester station 1 then it needs to be saved to the good parts excel file, in the ABC sheet and in the good tester station 1 sheet.
If part XYZ comes along and is a bad part (fails testing) then it needs to be saved to the bad parts file, the XYZ sheet and the bad tester station 1 sheet.I might have added more detail than is needed to solve the problem but I thought I would add it anyways to help you all understand my problem a little better.

View 3 RepliesCreate Separate Object Instances For New Objects In Separate TabPages?
Sep 17, 2010I have a TabControl object on my form with many tabs created in code (TabPages) and my problem is that the same objects that are in the initial TabPage needs to be in the other TabPages created in code, I have this done in code when the user clicks the 'New Tab' menu option, however the same code is used for any new tabs created. The problem created here is that I have an event against one of the objects that appear in the other TabPages, but because the same code is used to create any new tab pages, the event will only work on the newest tab page, if that makes sense? By the way these objects that appear on the other TabPages are properties at the top so events can be handled against them in the respective subroutine.

Possible To Have Separate Combo Boxes That Will Give Separate ID Values But Using Same Table?
Apr 30, 2010I'll get straight to my problem - I'm currently coding in Visual Studio.I have a table (countries) with the columns ID | Name. The table is filled with around 28 records.I also have a form with 4 combo boxes (set up as 1,2,3 & 4) that I want the user to select. These combo boxes will display the names from the table countries. I then want to use the selected names in the combo boxes to Insert into their corresponding ID into another table. For example England would have the ID 1, USA the ID 2 etc.So, is it possible to have separate combo boxes that will give separate ID values but using the same table? At the moment I can't seem to find a solution.Eventually the form will have more than 4 combo boxes so I don't want to use separate bindingsources for each combo box.
