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.
using the StreamReader / StreamWriter code. I want to store a new password in a .txt document that will later be printed. Here is the code I have so far. The code runs but I cannot find the .txt document.[code].....
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?
I have added some files that I need to be downloaded to the Application start up path. So I set Build Action as content now the files have been copied some where C:Documents and SettingsTestUser.ANNAMLocal SettingsApps2.0DataHVDRBMY5.8AA858AT9VM.TNP est..tion_2d7cfc137d9c2c74_0001.0013_432bd4561850d290Data How can access file from the application. My problem since it is a dynamic path will it be same folder count so that we can use like ....Data Some think like this
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?
My If ListView1.SelectedItems.Count = 0 Then MessageBox.Show("Please select a class from the upcoming schedule list.", "Error", MessageBoxButtons.OK, MessageBoxIcon.Exclamation) Else
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:
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 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()
I made my own advanced networking system which uses System.IO.Streamwriter and Streamreader but offline. I would like to let this use a directory online, I have a webhost available for that, now how do I say to the program it has to look at a specific map with all the users information?
I now have already this into my login form:
Private Sub btnLogin_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLogin.Click On Error GoTo A
[CODE]...
Just curious if I can let my network grow out international instead of pc. Also I have a second question. I made a create account page which is supposted to make a text file with the txtUserName and txtPassword inputs, but it does create the file, but doesnt write any lines into it.
Code here:
Private Sub btnCreate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCreate.Click Dim UserGenerator As System.IO.StreamWriter
I want that clicking the btn1 it shows the OpenFileDialog and read file that it has got this structure: SKI10 1 71 0 0 18 101 19 0 29 101 30 0 40 101 41 0 50 101 51 0 62 101 63 0 81 101 82 0 95 101 2 0 0 95 165 3 0 1072 01 4 2 1 93 15
I want that it reads all Line of the File and it add an Item in ListBox for line.For example the first Item of the ListBox in this case is
SKI1
And the 2th Item is in this case.
0 1 7
I want using the StreamReader classes.And i want that when i click an Item of the ListBox it shows the Text in the TextBox and I can edit the Line and that clicking antoher button the Item will come updated with new Text of the TextBox.I have also another button for saving the Mod.I can use the AppendText and it create a new file writing ListBox1.Items line for line.
If SaveFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then Dim file_esistenteD As StreamWriter[code].....
i made an application vb.net 2008 express edition when i am debugging flash files r working fine when i am publishing the app flash files are not running?
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?
Is it possible to change the application version without publishing the application? Because I'm going to make an auto updater which needs some version information to work, but I don't want to have an installer.
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:
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 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 [Code] .....
I have recently created an application with Visual Basic.NET. I published my application and installed it. Now the question is that I need to know where exactly does the application gets installed on my system ?
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 need to get data from one text file and use it for a calculation in another text file.The first file has the students' current grade and the second file has the students' overall GPA,.I need to get that current grade(named 'qp') out of the first streamreader so I can use it for my calculation but it only gives me the 'qp' of the last student in the first streamreader.[code]
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:
