Importing Data From Text File Into Text Boxes?
Jan 2, 2010
I have a text file containing ten pieces of information (5 prices and 5 descriptions) I want to load the information from the text file in to the text boxes, so that it can be viewed and edited if required.
I've declared the filename, and various variables, but I'm not sure how to get the info from the file to my form?
filename = CurDir() & "/charges.txt"
Could I use something like this:
fileopen(1, filename, openmode.append)
do while not EOF(1)
...

I want to export data from a DataGridView to a CSV/text file. I then also want to be able to load that same CSV/text file and populate that same DataGridView at a later point in time. My information is loaded into columns in the DataGridView. That is, I am not using rows to represent records, I am using columns. As such, I need to load all the data in each column and export this, by column to the CSV/Text file. Likewise, when I load the control from the CSV/text file, I need to load each column with this information.How do you export/import from/to a DataGridView controlHow do you organize the data in the CSV/File

So I'm in the final stages of finishing a program I've been working on for nearly a year now, and this is basically my final hurdle. The Save dialogue is working beautifully, with 'flags' in order to switch it over from the regular input into text boxes to the Listbox input protocol.
However, I'm having a *** of a time getting it to take lines from the text file and put them in the proper text box. Here is an example file:
Quote:
SHOWNAME
CALLNAME
BREED
[Code]....
So with the sample file I provided above, in the textbox named callNameText would appear "SHOWNAME", and so on and so forth. With this build, I get a NullReferenceException on the "Me.Controls(strboxNames(i)).Text() = strAllText(ati)" line.

I'm in the middle of creating an application that will be used to input customer information whilst the customer is speaking to someone over the phone. This involves the customer giving the employee information such as name, address, postcode etc and the employee inputting that information into text boxes and combo boxes that are in the application.
What I would like to be able to do is after the customers information is given over the phone, I need to be able to send that information to a database which will probably most likely be done by button click. In this case, I'm using Microsoft Access. I'm also hoping that I can do this within Visual Basic coding.
The database is set out with multiple tables which include a customer table and a ticket table and both have multiple fields such as first name, surname in the customers table. Both of these tables are in use with the information that the customer gives over the phone.
I've already asked on other forums and people are where replying giving me third party programs that I could use to implement this, something I don't really want to do.

I've been writing a weight program for flooded pressure vessels and I'm having trouble retrieving the data from the text files I've been saving. I know how to write the data to the text file, but retrieving it with OpenFileDialog is not so easy for me.The user has individual text boxes that they input strings or numbers into and when they save the file, each text box input is written to one line in the text file. For example, the first text box is for the username, therefore the first line of text that is saved is the person's name, the second text box is the customer, thus the second line in the text file is the customer name, and so on.
(Actually, the first line of text in the saved file designates whether English units were used or Metric units because when the user retrieves the saved file, English units will open one form and Metric units will open a separate form, so some If...Then statement will need to occur).I need to be able to read the first line, have either my "EnglishForm"form open or my "MetricForm" form open, and then have each subsequent line of text be displayed in their corresponding text boxes. I know I need to use ReadLine or LineInput, but I don't have a clue what to do.Assuming the syntax I've displayed below would just magically work (if only life were that easy), it would look something like this
If FirstLineOfTextInFile = "English" Then
EnglishForm.Show()
ElseIf FirstLineOfTextInFile = "Metric" Then[code]....
And so on...I read a lot of articles from the MSDN library and exhausted each link that I've looked through from Google and Bing, but most only retrieve data from the file to a single text box through some loop or streamreader and don't take into account multiple forms.

I'm trying to read a text file that contains info like this:
ACX-101-011 , J2168
BTXR-130A-013, D6733
AJ4-233-614, T8211
I want to split each line at the comma and write the left side to a textbox and the the right side to another textbox. I'm close, with the code below, but I can only post results from the first line in the file. How do I loop this and append the text results in each of the textboxes.
Dim TempFile As String
TempFile = "temp.txt"
Dim sw As StreamWriter

how to permanently save to text files then re-open all of the information again using SFD and OFD. Now my teacher has come back at me and said that i need to be able to save the information from multiple text boxes and have the text in certain labels to also be saved into the one text file (the labels need to be done because it is a database and these labels are like the fields and the right text box needs to match the right label)

I need to to able to save multiple text-boxes and a combo-box to a text file. the thing is, when I go to save, I check out the .txt file manually and its saved all in one line, no spaces. when I go to "read" it with the 2nd part (<-----this is a 2 part Challenge) it even reads all from that one line in the text file. What i'm asking is how can I make my text-boxes saved in the text file on different lines. [Code]

I am trying to follow the book 'Sams teach yourself VB 2008'. It was going well until the end of hour 4. For exercise 1 I have created the form with a button and two text boxes, but cannot work out the code I need to move text between the two boxes. The Object Browser does not seem to help - am I reading it wrong?

I have been able to load up the file, in to one txt box, but am unable to separate the items in to their own box. Should I be using arrays for this?

When the connections is successful (which it does when ran). Button 1 Writes to the text file (which it does successfully). Button 2 deletes the contents of the table and not the table itself (which it does successfully). Last, button 3 is supposed to read the text file and insert each field which is separated by a comma back into the existing table. However, at the "addComm.ExecuteNonQuery()" step I receive an error (An unhandled exception of type 'System.Data.SqlClient.SqlException' occurred in system.data.dll). I have spent many hours trying to find a solution but can't seem to get it to rewrite the text file back to the table.[code]...

I have a large text file that I want to use in my project, that data in the text file has about six items for each location. Now I had thought of importing the text file into a database using Access, but not had a lot of luck making it work. The question is is it better to load the data in the project as a text file then search for the string required or to convert it into a database. (The text file is a list of airports and related data.) Can a text file be converted to a Microsoft compact SQL database?

I have a data set with a parent child relationship between a patient table and an insurance table. There can be up to 4 insurances for each patient. I want to display them in 4 separate panels of a vb.net form. So if a patient had 2 insurances, then txtName1.text on panel 1 would have the company name of the first insurance, txtName2.text on panel 2 would hold the company name of the second insurance, and so on.
How do I display only the insurances related to the current patient? I've tried moving through the rows of the related table, but that gives me all the rows, not the ones I need. Everything I see on the internet suggest using a datagrid, but that's not an option in this case.

im having a issue where not all the data from my dgv is being loaded into text boxes on a 2nd form. What im doing is using the "DataGridView1.CellDoubleClick" event to open another form and pass the selected row into seperate columns, this works great but as i added more columns to the DGV it seems that the form is loading and not all the data is loading into the text boxes. Is there a way to halt the opening of the 2nd form until the loading is complete? i tried to simple "sleep" at the end right before the form is made visible but that didnt work. heres the code im using to load the DGV into text boxes, there are 16 columns, this is just the first one:
Code:
Edit.Item.Text = DataGridView1.Item(1, i).Value
as i said before, 13 or so of the 16 work fine, its the last few that refuse to load

Basically what I'm trying to do is read a text file line by line. After each line is read, it will put each line into a separate text box. I've been trying to do this for a while and so far I haven't been able to. I tried using a for loop, but that just put all my lines in to one textbox.
