Publishing Vb Application With StreamReader/StreamWriter .txt Files
Mar 4, 2012
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.

I am using streamreader and streamwriter to read a text file , change the text, then write to the same text file. This all happens in a loop every second or so.Currently I use:
Dim csetpointfileread As New System.IO.StreamReader("C:webcsetpoint.txt")and Dim csetpointfile As New System.IO.StreamWriter("c:webcsetpoint.txt", False)before every file read / write operation, it gets dimensioned every loop. To me this seems like a waste, and should only have to be dimentioned once. If I try to run both statements in the beginning, outside of the loop, the second statement wont work because the "file is allready open". Am I missing something or am I doing it correctly to begin with?

Using: VB 2008 Express?I created an application that connects to my MySQL, and everything works fine, but...
1. On my development computer, Windows 7, 64bit, I add the MySQL.data.dll file as a reference. I publish the program, run the setup.exe, and sucess.
2. I then copy my published folder to my test computer, Windows Vista 32 bit, and upon running the setup, the program fails to work because it cannot find the Mysql reference.
3. I then transfer my entire project over to my Vista computer, publish the program, run the setup.exe, and sucess.
4. I finally found out what was happening. My Windows 7 comptuer was not including MySql.Data.dll.deploy file in the Application Files published directory; but when I compiled it on the Vista machine this MySql.Data.dll.deploy was included.
So, in the end, I cannot compile the program on Windows 7, because it fails to create the .deploy file, and use it on Vista or XP (for some reason Win7 doesn't need this .deploy file?); but I can publish it on the Vista machine and install it fine on Windows 7, Vista, or XP. My targe CPU setting is Any computer.

I am writing a click event to delete an item selected from a list view which will utlimately be deleted from the csv file the information is coming from.Currently I am having streamreader read each line and then replace the selected line with a blank line. This creates blank lines in my csv files. Is there a way to delete a line using sr or sw without creating blank lines?Or is there a way to have them read/write a file skipping any empty lines?

I'm creating a text file and, among other things, I need to write the text of the parent and child nodes of a TreeView to the file. I know how to write the contents and read them just fine, but what I can't seem to figure out is how to write the contents if I don't know how many parent nodes or child nodes there are. When I do, I usually do the following:

To automate mailmerge function in word, i need to join different elements to complete the mailmergedatasource. In one of these file are words with special characters like ©, §,¨, .... When openng these files for reading, streamreader transfoms the characters to unreadable signs. When i give a type to use to open like ASCII, Unicode,it works for one or tho characters but not for all. I have the same problem when the character is read correctly, with streamwriter output to a textfile. Word cannot read the textfile and ask to define which type of coding should be used. In most of the cases not all the characters can be converted to readable characters.

I am trying to use filestream and streamwriter / streamreader to have a simple text box where the text entered is written to a text file, and then a button can be clicked to read the file and present the text back to the textbox. It works, but the problem I'm having is that if i change the text to something smaller in length (less text) than what is currently in the file, then press the button to read the file, it still contains some of the old text that was previously in the file.
Dim strmReadFile As New FileStream(txtPath.Text, FileMode.Open, FileAccess.Read, FileShare.Read)
Dim readHandle As New StreamReader(strmReadFile)
'read the entire text, and set it to a string
Dim streamFileContents As String = readHandle.ReadToEnd()

When a project is built in VB, the executable file is created in the \bin\Release folder. Apart from the executable there are other files that get created:
MyProject.application
MyProject.exe.manifest
MyProject.pdb
MyProject.xml
Are these files required to run the executable? Is having just the MyProject.exe file in the setup enough? And what are these files for?

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 am reading data from an API feed and saving the chunks into files. When the files reach 2 MB I start a new file and write to that file. What happens now is that an entry (<entry></entry>) can get cut off at the end of a file and continues into the new file. I try and reconstruct the files by taking the last entry and combining it with the first entry of the next file but this is tedious handling the data transmission and file creation.
Do
timestamp = DateTime.Now
numbytesread = responseStream.Read(bufferread, 0, BUFFER_SIZE)
If numbytesread > 123 Then
'timestamp = DateTime.Now
responseData = Encoding.UTF8.GetString

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.
StringForTextFile = "C:" & Folder4PS & "" & IDCodewDashOrN & "Series" & Series & "ScreenNumber" & ScreenNumber & ".txt"
LblTesting.Visible = True ' Testing
LblTesting.Text = "StringForTextFile = " & StringForTextFile
[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 could not figure out the key to installing folders/subfolders/.rtf files during deployment/installation. The key here is to 'add' folders and subfolders to the project in solution explorer, then adding existing item (.text (.rtf files in my case) files) then selecting the .rtf file in solution explorer.go to its properties and under 'Build Action' select 'Content' (very Important!). Then under 'Copy to Output' select 'Copy if newer'!Then in code to access these files you use the following code:
Me.RichTextBoxDisplay.LoadFile(Path.Combine(Application.StartupPath, "KJV BibleOTExodusExodus KJV.rtf"))
Finally after 3 days of research and 2 days at the msdn forum picking peoples minds (smarter than mine) and lots of prayer, I got it!
