I have a Windows Forms application that is filtering out Visual Studio solution files.
I have the code thus far to search and find the correct files and to differentiate between VS2005 & VS2010 solution files.
Now I need to write/save these files so that I can retreive them all from the same location. I need to use Streamwriter but am not too sure how to code it.
I have included my source code so far and code for the Streamwriter write and save?
I want to develop an application which can Write, Save, Read text files(or html files) What I want the application to do is. When I open my application I can write stuffs and then it will save it to my hosting/server. Then, the application will read the text which I already save.. So far, I can only make the application read it by using WebBrowser control and navigating it to a specified URL. Example: [URL](or message.txt) Which I modified from the website not from the application. I want to modify the text or html files from my application.
I'm trying to write a CSV file with multiple fields. The data to be written is stored in a list(of string()). Using VB Filewriter.Write for each field, the process is real slow. Isn't there a way to format the data first and use Writeline once for each instance in the data store? Unfortunately, when I created a string with all the fields concatenated and separated by commas, the Writeline inserted quotes around the whole string. How do I prevent this behavior?
encountering a problem when trying to write data to a text file. If I put the output into a messagebox I can see it, but when I attempt to write it to a file it is just blank. What am I missing here? EDIT - This is just a simple winform that I specify a path to a local HTML file in Textbox1 and I'm attempting to parse some HREF tag data.

I have a code which reads a text file through streamreader,selects what is important and writes the same to another fileusing streamwriter. The problem is that the streamwriter stops writing beyond a certain line and just doesnt write ahead.What can be the problem? Do I have to make two seperate files?
I have successfully run a simple sql query in vb.net and basically wanted to know how I can export the results from the query to a .txt file? All I really know is that I should be using StreamWriter. "SELECT column1, column2, from table1 where column1 = '1'" to a .txt file? Would it be best to first bind the data to a grid or can I skip that step?
I need to update the students score with a new score but I cant get it to write to the line that the students current score it at. It just deletes the whole text.
I am trying to read the content from a .csv file and storing it in a variable. Later I am writing that content into a newfile. Code is executing successfully but the data is not appearing in new file. Here is my code:
I have the following code, which I run everytime I want to add a new line to my text file, but it is deleting the previous data in the text file every time I do it.
Dim stFilePath As String = "C:file.txt" If File.Exists(stFilePath) Then Else File.CreateText(stFilePath) End If Dim ioFile As New StreamWriter(stFilePath) ioFile.WriteLine("{0}: {1}", DateTime.Now, "test message") ioFile.Close()
Dim fs As New FileStream("C:est.txt", FileMode.OpenOrCreate, FileAccess.ReadWrite)Dim b As New StreamWriter(fs)
b.WriteLine("hellothere") : b.Close()
b.close is necessary to save changes to the file, but then, fs will be closed, too. is there any method that does the same thing but doesn't close fs, like "b.save"???
i need help with stream writer, i can get it read lines and stuff like that but now i need Streamwriter to write to a colour.txt file (already populated with data) and insert a line that isn't already in the file, into alph order eg combobox reads and displays list from txt file.
their is a colour thats isn't in the text file, so i would like it to take the colour from the combobox that was typed in by the user and place it into the colour.txt file in alphabetical order (these are car colours so their are 100's and 1000's per manufacturer, its not as basic as i want red blue black lol) i was able to find loads of data about streamreader but not so much about stream writer
I am writing code in hopes to develop a template for estimating the cost of concrete driveways. The program is going to take information from several box's on the form then save some of the info in a ".txt" file. Next I want to be able to print off the ".txt" file without reformatting it. This is where i am having my troubles. I can retrieve my file but its all in one line. Is there a simple way to add a carriage return?
So, im using streamwriter and i want to create a folder and then save the text file in that folder.Here is the code im using right now.Imports System Imports System.IO Public Class Form1 Dim nr As Integer = 0 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Using sw As StreamWriter = New StreamWriter(DateAndTime.Now.ToShortDateString & ".txt")Add some text to the file.
I want to create files based on the particular value of supplied recordset using the StreamWriter at RunTime. The files will be dynamic these will be create based on particular field.Example: If I have list of employees, I don't know from which city of the country they came from. I want to create a different files for every city and write those employees in to the corresponding files at runtime.
I have thios code that will load a php file (text file) into a sting via streamreader then its supposed to find and replace a portion of the text and write the changes back out to the file via streamwriter. I put my code together and after running it look at the file and it's unchanged. After looking closer it appears the problem is the find & replace operation I am doing on the string. Here is my code:
In my code I've allowed used to create their own mazes and save them, under whatever name they like. I've also included a few pre-created mazes. The mazes themselves are saves in .txt files in the bin/debug folder of the project, along with a .txt file containing the maze names.
I really need to publish this program to send it to my teacher, but when I publish it it doesn't include any of the .txt files in my bin/debug folder.
All right, here's my issue. I have a resource that is a text file. I'm trying to use a StreamWriter to edit it. I've done it in C# but can't find my example files.
I'm getting a problem when writing text files using StreamWriter. The files read fine and they write fine if I'm not overwriting an existing file. They also write ok as long as I'm not writing over a file that only has one digit at the end of the name. For some reason when there are 2 digits at the end it crashes when I'm trying to save over an already existing text file. Here's my code.
above but 've tried all the different Encoding possibilites. Unicode, UTF32, UTF8, UTF7 as well as without those parameters listed where the close parentheses is right after StringForTextFile. I get the same result. If I'm writing a new text file that doesn't exist, then no problem or if I'm writing over an existing text file but it has 0 to 9 at the end then I'm ok but if I'm writing over an existing file and there is 10 or above(haven't tried triple digits or all values) then my application crashes. You see the test label in the code above because I was looking at exactly what file it was trying to overwrite and it is just as it should be.
Should I be using a different procedure? An example of a string that would cause a crash for the string StringForTextFile would be:
C:Name of My AppSeries1ScreenNumber10.txt
If it was being written for the first time then no problem or if the 10 at the end was 0 to 9 then no problem also. I've also tried and originally had it set up where there wasn't an If File.Exists(StringForTextFile) = True Then statement. It just always used the same code whether writing or overwriting and I wasn't having a problem that I remember. For some reason I started having a problem recently and I put the alternate methods of writing in.
I am taking in two html files and creating one out of them. To do this I am opening the first html file and not writing out the closing </body> and </html> tag and opening the second file and not writing out the corresponding opening tags, as well as the <style></style>section. I start a streamwriter, and write the lines out to it, and then close the streamwriter. My problem is that the output file is filled with strange characters. I've tried opening the streamwriter with different character sets as the third parm, but all this does is change the characters to different strange characters.It says charset=windows-1252 at the tops of the input files (and the output files for that matter - since I'm just reading stuff in and writing it out - with the exceptions mentioned above).Questions;First, do you think I am properly approaching appending two .htm files together?Second, how can I eliminate these strange characters.

The problem is that if I save a file I get "myfile.GDL" if I overwrite that I get a new file "myfile.GDL.GDL" ect.the other problem being that the filtering in the windows save/open dialog wont show .GDL files unless I select "all files".

I am trying to save multiple text files using a save dialog.
I can save one textbox
SaveFileDialog1.ShowDialog() Dim File As System.IO.File Dim Write As System.IO.StreamWriter Write = File.CreateText(SaveFileDialog1.FileName) Write.WriteLine(TextBox1.Text) Write.Close()
but I don't know how to save multiple textboxes and richtext boxes. Would I have to use a screenwriter for this?
I am trying to find a way to allow my users to choose the directory to save files into, THe file name is automatically generated as it has a naming convention and i am able to pre program a location to save to but i d like to be able to allow my users to decide themselves which directory they want to save the files to and to have the ability to choose which directory to save to
I have recently moved from XP Pro VS2008 to Win7 Ultimate VS2010 and all the sudden I am unable to debug code and I can't write log files (ex: c:mylog.txt) anymore. What am I missing here? I am using the same code that used to work.My biggest issue is my inablility to debug. I was writting a quick app to check a service on a remote machine and I wanted to debug this app to trap all the possible errors. So I pointed my code to check my service local. [code]
I am designing an interface using vb.net and the values inputted there should be saved in a database and I choose to design my database using mysql in phpmyadmin. I already made my database in php via localhost/phpmyadmin/index.php. But I do not know what commands / codes should I write in vb.net so that i.e. the value of textbox.text would be saved in database.
