I have a text file containing 10 pieces of information. I want to read the information from the text file and put it in text boxes on a form, so that the user can view the information and edit if required. What is the best way of approaching this?

i have 5 textboxes in a form. I have a streamwriter that writes all of their text to on text file like this:
Code:
Dim xfile As String = Application.StartupPath & "/Set.txt"
If File.Exists(xfile) = True Then
Dim writex As StreamWriter = New StreamWriter(xfile)

I was wondering how to get the text under the each number and place it in the corresponding textbox.
I know how to load a txt file into a single text box, but im having trouble loading a text file with multiple output information into multiple text boxes using commas to separate the information.
ex)
txtfile:
123, Employee Name, Employee DOB

how to move info from text boxes on one form to binding source text boxes on another form. I am displaying array info in text boxes on one form and i need to add them to the database on another form. How do I do that?
View 5 RepliesI 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?
View 14 RepliesI have code which saves DGV contents including check box columns as a comma separated text file. I also have correct code which will take the text file and re-insert it into the DGV at a later time. This all works.When I'm working on the DGV, I have this
Private Sub DataGridView1_CellValueChanged(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellValueChanged
If DataGridView1.Columns(e.ColumnIndex).Name = "Column12" Then[code]....
So that when the check box is true, columns 1 and 3 turn different colours, and when false, go to a yellow colour.However, when I "re-insert" my DGV info from my text file, the check boxes come back correctly - as true and false on the right rows - but columns 1 and 3 don't change colour. I've tried a "DataGridView1.Refresh" option but not getting it to work.The DGV is unbound. I need it to recognise which check boxes are true and update automatically when the information is opened from a text file.
I need to read information from excel and them put them into a text file,I have the part for text file done and write to it but I dont know how to go and read from an excel file where every row is a diferent record, so I need to read the entire row and put every cell on variables so I can get my fixed text file done.

After I have entered data into 12 textboxes and pressed a button to execute the code, the data from the text boxes goes into a database.I want to clear the information in the text boxes after the button has been clicked, at the moment I have 12 lines of code which are similar to this.
MsgBox("Data Has been Added to The Database")
tbeventId.Clear()
tbtitle.Clear()
tbstartdate.Clear()
tbvenue.Clear()
is there a easier/simpler way to remove all data from the text boxes without using 13lines of code
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 think the problem arose because of Windows 7, but when I was at school the program worked. The program fills in the text boxes with information from Microsoft Access. However, my laptop has Windows 7, and when debugged, the information doesn't fill in the text boxes like before. Also, for added information, the school's computers run with Windows XP.
View 2 RepliesI have a problem in that I have five text boxes pertaining to a customer/client, where there is a txtbox for each: Name; Address; City: State; Zipcode. Of course all the txtboxes are "" at initialization. I also have 2 combo boxes and a 2D array for prices which I have finally been able to understand the array logic. I have also been able to do my necessary calculations for.
My problem. The customer information is first to be validated as all being strings and not empty. The combo boxes I was able to get to tie to my 2 dimentional array and get good output and calculations for a finished product. I am just having problems with the error messages. Also I don't want summary totals unless the data is valid. In other words, the user must enter a complete address and make decisions about the two combo boxes, both of which are needed to use the price array. I will change the comboBoxes to represent dress sizes,"S" "M" "L" and "XL" and the other combobox to describe colorRedSatin or colorBlackBroadcloth with a two dollar difference in price between them. 'That would be similar enough to the problem I need to solve.
Basically I do not want any numbers to appear for price of the dress or addons to the dress unless all validation is complete. I do understand how the radio objects work for discounts and check boxes for accumulating accessories. The program should not give any totals untill the user has input all customer information and made decisions about input from combo boxes and selected calculate from menu. Right now it calculates and puts zeros in when choices are not made from the combo boxes by the user. It will include correct amounts for radio buttons and checkboxes if anything is entered. I need error messages for customer inputs and combo box inputs (if not selected from list of option in drop down for choices) (basically if nothing was put in a text box, the text box is empty. Of course the problem is the user must enter something in all 5 textboxes and not get multiple error messages in rapid succession to fix. We can't always count on our users putting in good data.. When I tried a Do While False with ORs I was getting endless looping. I could not get it to work because it will never execute because the control never passes back to the user.
I don't want to list a series of If/Thens becauser the user will see about 7 messages, where he/she only needs to be fed one at the time. I hope someone can give me some direction. I just need guidance on how to validate the text boxes and combo boxes. The code is analyzed with a "Calculate" on the menustrip. I would like for the calculation not to calculate and put outputs into the summery text boxes unless all textboxes are filled and combo boxes are valid for all the customer information and combo box choices for my two combo boxes describing what is needed for the order to calculate. There are also the radiobuttons and checkboxes, DIMs, Const, Variables, but not having problems with that part I have my indexing problems on the combo boxes worked out also, so I am not concerned about those now except for getting the error messages when I should. I hope that I have described my issues fully. I am using visual studio 8 with Windows 7
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)
View 39 RepliesI 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]
