Saving Information From Different Form Into Same Line Of Text
Jan 29, 2010
I am creating a save function for my program and need to save information from different form into the same line of text in a text document. I have to get the date (from vb), the persons name (on frrmDataCollection.tbName) and their BMI (its calculated on frrmDataCollection from a button so i dunno how to do this bit). I then need to put it in a text document on my hard drive (C:BMICalculator). Here is the code that I have got at the moment 1st for the conversion and 2nd for the save function.
HeightAnswer = CType(tbHeight.Text, Single) * 2
WeightAnswer = CType(tbWeight.Text, Single)
BMIAnswer = WeightAnswer / HeightAnswer
frmBMIResults.tbResults.Text = (tbName.Text & ", your BMI is " & BMIAnswer)
frmBMIResults.Show()
Me.Hide()

using as an example DPText = "AxBxCxD"; I am looking for simple VB.net routine/commands to:
(a) Return the positions of particular character(s) within the text (in this example, return 2, 4 and 6 as numerals for the positions of "x"), and;
(b) Return a portion of the text when providing the position within the text (example, return "C" when providing 5 as the starting position within the text and 1 as the length of the text sought).

I have a form that contains a RichTextBox control that I have set to multiline. I also have a menu item that allows the user to save the contents of the RichTextBox as either a .rtf document or a .txt document. Here's the code I'm using so far:
If sfdSaveTextFile.ShowDialog() = DialogResult.OK Then
m_strDocFileLocation = sfdSaveTextFile.FileName
m_strDocFileExtension = System.IO.Path.GetExtension(m_strDocFileLocation)
[Code]....
into the RichTextBox control (rtb) then saves as a text file this would save the text file like: "TempTemp"
Is there any way to write to the text file with line feeds included?

I have a form in an application that I'm building and in it I have a datagridview that when a user clicks a checkbox on a line in the datagridview and "submits" the data, then the form will insert all of the data on that line (along with the code "Holiday") into a database. Currently if I click in the checkbox on any line other than the first line and put a line break on the "Try" statement, and then fire the submit_onclick event, I'm never reaching that break point but if I click on the checkbox on the first line and submit that data, that works and it behaves at I stated above. Here is the code as it stands currently:

Basically iv got a form, and the fields are
"Full Name":
"Amount Contributed in �":
below the form i have a button that saves the data to a text file called 'mailinglist.txt'
So i enter the data into the fields and click the button like as follows:
Full Name: John Smith
Amount Contribted in �: 40
However..... when i go view the text file it displays John smith40, which i want a space between the name and the numeral.
Also as i want a maximum of 5 people added to the mailing list, i would like a function that lets me somehow "adds" an extra 4 people to the text file without overwriting the 1st name, and uses the same "current" form displayed to the user.
Here is the code as follows:
Public Class Form2
Private Sub TextBox2_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox2.TextChanged

I have a Form with a TextBox, and a Save button that saves the text as a .rcp (txt) file. Now I want to add a button that browse for an image that accompany that txt file, and load it into a Picture Box. When I click to Save the txt file, I want it automatically to also save the loaded image With the txt file as the same name as the txt file, without needing to save the image and text separately.
I have this code for my save button:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
SaveFileDialog1.CreatePrompt = True
SaveFileDialog1.OverwritePrompt = True
' Set the file name to myText.txt, set the type filter

I've been looking through the FCL for a method that will allow me to erase a line of text from a text file and replace it with another line of text. Neither the StreamReader nor StreamWriter have a method for replacing or removing Text from a text file, as does the string object. Are there any available methods for erasing just certain lines of text from a file, and then replacing them with others?
In my code, I'd like to locate a certain line in the text file, and then at that point in the text file, use a For...Next Loop to replace each successive line of the text file with new text:
Dim user_data_file As String = "user_data.txt"
edit_input = New StreamReader(user_data_file)
Dim edit_line As String = edit_input.ReadLine
[CODE]...
However, I can't find any methods that will allow me to do this.

I am trying to create a program that will have an option to automatically log you into a couple sites when you press the Start button. I have a separate form that you can open and put in your Username and Password for each site. There is a button that when you press it it is supposed to write to a file (C:DesktopAccounts.txt) you username and password so that when it is opened again you will not have to type them again. I had it working perfectly until I added some code so that it will remember if you had the check box checked and have the text box as read only (if check box is not checked). I even tried deleting the new code but it still will not write to the file, but it can read from it if I put the information in manually.

I'm trying to remove a line from a text file that begins with a set value.
The idea would be to paste values into a Windows form, which then finds each line that begins with that value (a 5 digit number) and removes those lines from the file, and then removes the gaps.

I have run into a problem with saving to database when running the program I am making.
I have an mdf file called prices.mdf and have set the "copy to output directory" to copy if newer setting and set this for the ldf file build action is set to content.. should it be compile or a different setting??
I access this database thru a dataset called pricelist dataset and when the program runs and you go to forms to update the prices, each form has a datagrid with the toolbar and the save icon. Mostly I followed tutorials to help me put it together.
When you run the change price menu for each part of the database, they appear to save each time u re run the program. But once you close down vb2010 and reopen it a day or so later and rerun, the new prices are gone and the old prices are being used.
I thought changing the setting on the mdf file to copy if newer is the usual fix for this, but as I said I have already got it set to copy if newer.
I can't figure out how to track what the dataset is accessing to make sure it is going to that database, or if i have made some sort of other database that it is accessing instead as well as the mdf database.
when I look at the dataset and the column entries for each part of the prices database, as to whether i need to check the dataset itself, or the forms the datagrids are on with the toolbar save icon, or whether there is another place to check to see if it needs to be changed to something like change if newer.
Obviously the program is working and doing the changes, but not storing them in the right place, so I am losing the changes once i shut down my project and reopen it.
also I have looked at the file propertiesand made sure they all set to copy if newer PricelistDataSet.xsd, pricelistdataset.designer.vb, and also the pricelist dataset.vb, xcs and xss ones are all set to copy if newer when I look in the solution explorer.butsome of the build part is set to compile on some and none for others As I am not experienced with VB 2010 or databases I am not sure how to track it down
Update: Just looked under each of the forms the data grids are on. and see the copy to output directorys on these are set to do not copy for each of the designer.vb, vb and resx. I am bit hesitant to change these without getting some advice from more experienced people if the forms also need to be set up to copy if newer.
This is what is shown in the coding on one of the forms if u double click on the save icon in toolbar
Private Sub TimberpricesBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TimberpricesBindingNavigatorSaveItem.Click

It was coded by dragging the things from the dataset as a datagrid onto the form. It is not coding I worked out, in case more needs to be added to the coding

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.

I have the same problem that Niphoet had in this thread: vb .net overwrite a specific line in a text file
I am trying to implement the code that Axarydax showed in C# that I am trying to translate to use into vb.net. My problem is that the code will make my new text file but will not write any of the lines from the other text file to it and just leaves it blank. I think my problem is with the while loop statement but I am not sure.

i want the user to login, and the first thing is, having the text document for that(if theres a safer way to do it, let me know) then it goes to the weekly sales page, but theres also the goals for the sales, which rarely change, but if they do i would like them to be able to change them, then next page is the list of the workers, and if they need to i would like them to be able to add workers. so my question is: is there anyway that maybe i could save both the goals, and the workers in the text document, and when they need to change it/add workers it will save it in the text document and the next time they sign in the changes will be permanent? also is there a way to delete the user once they have been created, other than going into the txt document and deleting it.
