I'm making a personal program (So it doesn't have to look nice or be super sleek) that is basically an alarm clock. I set the time and date, it writes it to a text document then it reads it from the text document back into another textbox that is hidden and compares it to label1.text which is my system time and date.the problem is, I have it so that I can add multiple dates in one document so when I enter one it'll do as so [code]how can I make the program read 1 line, wait for it to match the label, (I already make it display a message box) and then after that is all done, go to the next line and wait for it to match. etc etc.

How Can I make my textbox1 show the continents of a text file but I do not want it to show it right a way I want it to write one character at the time like typing it.
View 11 RepliesI'm having trouble reading in the file and populating the textboxes accordingly. After loading the file (I think that is) nothing is being populated in any of the textboxes listed below. Basically I'm not sure if the file is being read or not.
If OpenFileDialog2.ShowDialog() = DialogResult.OK Then
If My.Computer.FileSystem.FileExists("path_to_file") Then
Dim ioFile As New System.IO.StreamReader("path_to_file" + "filename")
TextBox1.Text = ioFile.ReadLine() 'Adds the first line
TextBox2.Text = ioFile.ReadLine() 'Adds the second line
TextBox3.Text = ioFile.ReadLine() 'Adds the third line
TextBox4.Text = ioFile.ReadLine() 'Adds the fourth line
TextBox5.Text = ioFile.ReadLine() 'Adds the fifth line
End If
End If
I can retreive all items in my notepad but when I am adding them up in my listbox, and trying to print them in the console. I can only display two strings. I don't know why. My string is a combination of a name, space & score. ex: "luke 300". That is the pattern of all strings per line in my text file. I am separating the name and the score using space as the indicator. When ever a space is found, string before and after the space is retrieved and added to the listbox
Here is my
scorelist = New ArrayList
reader1 = My.Computer.FileSystem.OpenTextFileReader(My.Application.Info.DirectoryPath & "scores.txt")

I've setup a TextWriterTraceListener which outputs the debug messages I've written to a file.This works fine however what I am trying to do know is output the content of this file to a textbox using a streamreader object.I originaly thought it may because I did not set the text file to allow read/write access so I changed this by setting the following:[code]
View 4 RepliesI have a txt file, that i want to read into my program. The problem is this:The textfile is a stats file for a game and looks like this:
Code:
ip:port wins username points
ip:port wins username points
ip:port wins username points
ip:port wins username points
ip:port wins username points
etc.
The main thing i want to do is sort these things out and then add to mysql database table that would have these columns:
Code:
ip authid wins username points
So what i wanna do is splitting this textfile data up and then adding everything to a mysql table.
If I do the following
FileOpen(f, Application.StartupPath & "data.txt", OpenMode.Input)
While Not EOF(f)
Input(f, t) 'read data line how do I get to keep the leading whitespace
ie in the file there is
"one"
"two"
" three"
I want to keep the space at the beginning ie t=" three" but t="three"

View 1 RepliesCan you look at my coding and let me know what I'm missing or doing wrong?I have a SSRS report that is called from a ReportViewer control and the ProcessingMode for this control is Remote. The report also has 1 parameter in it's DataSet.In the code I placed a MsgBox to make sure the code is finding the parameter and returning the parameter name. I am trying to stick the value of 10 into the parameter for playerID 10. Data for this player does exist.
I believe I need to add some more code to make this work but I'm not sure what else to add.
When the code executes the report is displayed but no data is shown in the report.

I've got the following txt file:
[code]...
Now I want that presented in the listbox with the semicolon and it should be aligned per column so that the numbers, the names, the prices and the quantity are exactly aligned per column.If I read the file like this:
[code]...
Then the semicolon is not presented in the listbox and I don't have any alignment per column. As the names of the woods are not equally long the prices and the quantity are not aligned directly below each other...
My questions are:
1) How to add the semicolon in the listbox as seperator of the columns
2) How to align the 4 columns in the listbox (as I have an array Item(3) )
Later on I need to be able to change the quantity (last column) from 0 to > 0 (that's why I have to use an array)
I am starting to learn reading and writing to textfiles. One quick problem. My code here
'Read is the variable that will read the kp.txt file"
Dim read As IO.StreamReader
read = IO.File.OpenText("C:2/kp.txt"[code].....
however when it is read into the listbox those 3 words appear on one line in listbox
How can i make it so that each line of the textfile is placed in each line on the listbox?
I'm making a program which has 7 textboxes. I intend the program to be used for classes in school, so the text would be like 2D Art, Geology etc... whatever your classes are. I have figured out how to use the streamwriter to take the text in the textboxes and write them to a .txt file however, my issue is with loading the text from the .txt file back into the textboxes. I did figure out how to write it so that all the text in the .txt file is loaded back into textbox1 but I have 7 textboxes... Here's the coding for the Load button:
Private Sub Button46_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button46.Click
Dim MainWindowLog As String = "V:Users(O.o)~(--_--)~(o.O)DocumentsVisual Studio

What I'm working on now is a basic telephone directory.a Directory text file contains the names of all of the subdirectories.The subdirectory files contain the names and numbers of all of the students/employees etc.Anyways. I've actually completed the program itself I just need to get the output formatted properly.Which leaves me with my problem. I want to output the data to some sort of grid. I'm going to assume DGV since it allows my to name columns(the column headings are simple: Name and Phone number)However, I cannot figure out how to take data from a textfile and throw it into the DGV. I know how to do it for a listbox, But I don't want a listbox since it isn't a grid. is there any way I can read my textfile data into an array and then iterate the data and output to the datagrid?

View 2 RepliesI am trying to create a textfile and write some lines into the textfile. However, the code that i am using can only write when the textfile is already created in the directory.
For this case, can i actually allow my script to search if a textfile is being created, if not create a textfile ???

I've made a browser project and beyond making it a default browser, I am having a problem with the Favorites feature TreeView control saving, loading and repopulating it with the users data. It's tough finding the correct code as there are so many variations of this control in various languages, but I did find sample code for loading and populating the TreeView with a text file using tabs to signify the node structure in VB.Net. (Most others I have found are VB6 or some other variation.)

What I am trying to do may be better for use with SQL Server but I have seen many applications in the past that simply work on text files and I am wanting to try to imitate the same behaviour that those applications follow. I have a list of URL's in a text file. This is simple enough to open and read line by line, but how can I store additional data from the file and query the data?
E.g.
Text File:
link1 - 0
link2 - 0
link3 - 1
link4 - 0
link5 - 1
Then I will read the data with:
Private Sub ButtonX2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonX2.Click
OpenFileDialog1.Filter = "*txt Text Files|*.txt"
If OpenFileDialog1.ShowDialog() = DialogResult.OK Then
Dim AllText As String = My.Computer.FileSystem.ReadAllText(OpenFileDialog1.FileName)
Dim Lines() = Split(AllText, vbCrLf)

Am I going completely the wrong way about storing the data after importing from a text file?

View 2 Repliesi was wondering if it possible to have a condition where lets say you have a column in the datatable called amount and a textbox acting as the filter called say maxamount to set it so the rowfilter when filtering the table will sum the number in the amount column until the number in maxamount is met, then stop and only return the rows where the total sum of the amount column is equal or less than the maxamount value, so i guess if the next row takes us over the maxamount it discards this row and returns the rows previous to it. is this possible using datagridview rowfilter or should i be loooking elsewhere to achieve this?

I have a form called FrmPracDetails which is built up with a List view called LvwColProc. Therefore when you click a field on the LvwColProc it takes you to another form called FrmColProcessing, here you can make changes to certain fields which are also present on FrmPracDetails. What I want to do is when you make changes on FrmColProcesing and Click the Save Button (which calls the Save function)the changes appear instantly on FrmPracDetails. Please note, FrmColProcessing will always be open next to FrmPracDetails. I have tried to put this code in the Save function present in FrmCol Processing as shown below, but it doesnt Refresh FrmPracDetails form. [code]
