I'm trying to read an entry in an ini file; if it reads "ShowInvoiceRequiredMsg=NO" then my program is going to give the option to change that line to "ShowInvoiceRequiredMsg=YES". My code below reads the file and picks up if the option is set to 'NO' but I can't seem to modify that line to change it to 'YES'....... (in red is where I'm trying to modify this text)
Dim file As System.IO.File
Dim reader As System.IO.StreamReader
Dim line As String
reader = file.OpenText("c:file.ini")
I'm fiddling around with trying to make a sort of map/world. I'm using 16 x 16 pictureboxes named PictureBox1, PictureBox2, etcThe issue is that when I put the images into all the pictureboxes, I have to have a line for each picturebox (so say I have 100 boxes, I have 100 lines).The only difference in each line is the picturebox number, the rest is identical. I'm basically telling it to set that picturebox's image based on the number that a variable I've created has stored.I've got a game idea, and I'm just trying to figure out how to do the map. I want it to work like the old school RPG games like Dragon Warrior, or the more recent Dwarf Fortress. I'm still not sure if I want to use graphics or letters. At this point, I'm just trying to figure out how I can create the main screen where the user moves around. This is what I've come up with, as it works with what I know. I'm pretty new to this, although I've messed around with VB6 a lot.
Dim tile(30) As Integer Dim tilelocation(3) As String Dim x As Integer
what i need to do is open a txt file, read line by line, decode each line into an array and display. Now all works ok apart from one line.
sTextLine = objReader.ReadLine() <-- Value of string cannot be converted.
full code here ------------- Dim objReader As New System.IO.StreamReader(sOpenFile.Text) Dim sTextLine As New ArrayList() Dim sText As String = "" Dim i As Integer = 0
How would i go about reading a file Line by Line that within that line The values are delimited by " Example of the data:
"bob" "cat" "1243" "steve" dog" "6789"
I've started this with this code but not sure how to go about the next stage:
Using MyReader As New _ Microsoft.VisualBasic.FileIO.TextFieldParser(My.Application.Info.DirectoryPath & "Records28112011.jd") MyReader.TextFieldType = FileIO.FieldType.Delimited
i am working on an application called logonscreenchangerxp i made my program and when i run it on xp virtualmachine i get errors the program is made using vb 2008 and using .net framework 2.0 i am not able to get full permissions to modify boot.ini file and a regisrty value and to delete a file
I am developing an application that Monitors a specific folder for file changes such as modify deletion, update, etc. The only problem I have is , the application doesn't fire up File events.
I'm reading a text file with StreamReader, line by line. If a condition is met, then I do an operation and then start reading the file again from the first line. I realize I could close and then re-open the file, but surely this would be very slow.
I could do this easily in VB6, but pulling my hair out trying to do this in vB.net. It seems that 'Seek' is the function to use, but it doesn't work.
I've seen other examples, where it works, but you must open it a different way -- with a file number.
Imports System.IO Dim I as Integer Dim LineText as String
I have (with help from you) got 'full' control of Canon image capture and processing with feature recognition, and USB cam capture including frame modification on the fly. I now want to read an avi file and modify it on the run. I have found several C# and C++ routines as a good basis, (Especially the steganography example) if only I could successfully convert them. Unless I understand what I am doing wrong I don't stand a chance. So - start with the absolute basic Open/Close avi - This fails - Protected memory eror
[Code]...
I can hardly think about streams til I can open a file, but when it is functional to the access to frames I'll submit a final copy for othersto use
I have a CSV file with many rows in which I need to update/replace column four's value using VB.NET. There are no headers on the columns so the loop can start on row one.
infile.csv "value1","value2","value3","value4"
After much googling, there are lots of examples on how to read and write CSV files, but none quite what is needed. I know there are multiple ways to accomplish this task, but a requirement is that it's done with VB.NET.tFinal code ported from Marco's C# answerPrivate Sub CSVmod(ByVal strFileName As String, ByVal newFileName As String)
Dim strLines As String() = File.ReadAllLines(strFileName) Dim strList As New List(Of String) Dim strReplace As String = "test"
I have an application using Visual Basic 2010 Express. Basically I load an XML file into a datagrid and then wish to modify it. Now the following code works fine:
Private Sub Modify_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Modify.Click Dim da As New XmlDataDocument da.Load(Environment.GetFolderPath(Environment.SpecialFolder.Desktop) & "/events.xml") Dim path1 As String = "/calendar/event/title[text()='" & DataGridView1.CurrentRow.Cells(0).Value.ToString & "']" Dim path2 As String = "/calendar/event/text[text()='" & DataGridView1.CurrentRow.Cells(1).Value.ToString & "']" [Code] .....
Now the modify button does what it is intended to do as far as load the "title" and the "text" elements into the text boxes. However I want to load the other attributes into the text box. I.E. date, timeStart, timeFinish etc. Also, the just of this is to be able to modify an xml file without going into the xml file using a text editor.

I am developing desktop applications using .NET 1.0,1.1 thru VS 2002. I need your help. I want to view/modify file metadata like Author, Title, Company, etc. that file may be a txt / doc / exe / xml / html / pdf any format... I found an example for this in CodeProject site. In that project they give dsofile.dll and source code for viewing/modifying file metadata. I tried to register that dll using regsvr32.exe (regsvr32 dsofile.dll). But it couldn't be registered. even i tried to download setup file from microsoft site but it was not found. Please help me to view/modify file metadata info.
I am getting the above error when I attempt to run setup.exe as a non-administrator on Windows XP (sp3). This is for an application I created, and I would like to know what permissions the users need to install the application and updates. I am trying to understand the security issues when installing a vb.net desktop application, the .NET framework, and other resources such as the visual studio crystal reports engine. Any good resource which explains how this works for different operating systems and privilege levels?
I want to modify the third column of an existing excel file. The problem with below code is a new file is prduced with the new values in Column C and erases all other values in the orginal file. I want to update the orginal file with the new values.

I have text files with X Y Z data. There are three columns, one each for X, Y and Z and the files are tab delimited.The value of X is constant over a (repeating) range of Y. Z is the dependent variable.
For example:
0 1 44 0 2 32 0 3 22
[code]....
I need something to take this file and break into multiple tab-delimited columns. In the output, I would like the initial range of Y to be the first column (ie 1 to 4). Then, the second column should have the Z values for that domain (X=0 in above example). Then, the next column should have the Z values for the next domain of Y (i.e. 1 to 4 again, but now for X=5 in above example) and so on. Also, I'd like the first line value in each of the new columns containing Z values to be the X-value they were originally associated with.Thus, I'd like the output file to look like
I currently have a nightly build system running as a windows scheduled task, calling at batch file, that works sort of like this: Check out the latest revision from subversion Modify the AssemblyInfo.vb file of the main executable and the librarys to set the version number to 0.0.0.revision Invoke MSBuild to build everything (including the installer) Upload the installer and a log of the build to an FTP server This works ok, but step 2 is dirty and fragile, and I can't imagine that this the only way to do what I want. Any ideas?
I am currently working on an application which requires reading, writing and modifying data from a TEXT file. I have searched a lot but was not able to find a simple way to achieve this. I have to use a standard VB form with textboxes for this text file operations.
1. I have a button, and registry entries, each tell me what version and where it is located. Example : (reg path = HKEY_CURRENT_USERSoftwareTNL) Path = c:program filesmyprogram Regan = us
The program its launching is called caw.exe. but it requires diffrent locations in a file named realms.*** file to work properly. Basically if Regan = us, do this, else if regan = eu do that, else if regan = tu do this. I need to basicly erase everything in that file and replace it, the file location is located under : "PATH"/data/en"Regan"/realmlist.*** The PATH and Regan need to be replaced with correct paths.
2. After it has finished modifying the File it saves it and then Launches Path/caw.exe
Dear Friends: I have some files in 1 folder directory that show "XML Configuration File" under type. But none of these files show the extension .config. The directory filesare like C0150,C0150_new,C0200,C0200_new etc. I need to change only 1 attribute of each of these files. I need to write a VS.Net project to do this. I have to send the .exe file(from bin directory of this VS.Net project) to my client and they will just double click the .exe file and it will change that attribute in all the .config files.
The C0150 file looks like this: <?xml version="1.0" encoding="utf-8"?> <configuration>

I'm trying to read an .rtf file one line at a time but I'm clearly missing something!The file contains 3 lines and I want each line to end-up in a different RichTextBox, so:
Open File RichTextBox1 = 1st Line in File RichTextBox2 = 2nd Line in File RichTextBox3 = 3rd Line in File Close File
What am I not understanding? I've tried using LoadFile to load the whole file into another RichTextBox first as I got the impression that RichTextBoxes are indexed - but what I got was strings not .rtf format. I've also looked to see if there's an equivalent of the text-centric ".ReadLine" and nothing seems to fit the bill.
