I am trying to learn how to open and save text files with visual basic 2010. Here is code I have for now:
vb.net
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[code].....
So I have made a text editor using rich text boxes and it is made to save/open rtf files. I have 3 issues I was hoping to get answers for...
1. Can I (and if so how) make it able to open/save text files and rtf files (so the user can choose which way to save it)?
2. I added the ability to color the words, but instead of coloring just the highlighted parts - it colors everything in the file. How do I change that so it only colors selected text?
3. I also added the dialog for Font changes, but it does not seem to work correctly. I want it to change font/size/etc of whatever is selected. Right now when I highlight stuff and then go into Font it allows the dialog box but does not actually change the font size/type/etc in the file it has open.
Here is the code for the above 4 mentioned areas...
Save...
Try
Dim dlg As SaveFileDialog = New SaveFileDialog
dlg.Title = "Save"
dlg.Filter = "Rich Text Files (*.rtf)|*.rtf"
[Code] .....
im used to C programming.
Private Sub SaveAsToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveAsToolStripMenuItem.Click
timedate.Stop()[code]......
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 for example i save ppt in OLEDB OLE Object and i need to open this powerpoint file in my program how can i do that?
View 4 RepliesI 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 want it to do the following: When they click the import button, open multiple files (done) then save them as a settings. Then on form load, open those files so I do not have to re-import them!

I current have an app that I am trying to create. I have 2 List boxes, a textbox, and a command button.What I am trying to do is take about 100 text files that all have certain text in them that I need to change at run time to whatever I put into the textbox. For instance Each Text file has my old company name and I want to be able enter my new name into the textbox and click the command button and the app will open each text file, find the text that I specify and replace it with my new name then save the file into a specified folder.What elements should I be studying to make this happen? So far this is what I've come up with:
OpenFileDialog - to open the file
StreamReader - to read the text files and find the text that I specified
**Not sure on the replace method**
StreamWriter - to write the text from the textbox to the new file
SaveFileDialog - to save the file to the specified location

I am making a word processor, in VB 2008 and one problem I'm having is creating a save, print and open features. I have done the dialog bit, so when I click my save, print or open buttons the open, print or save window opens, but it's just the next bit that's mind boggling; writing a code so the file will actually open, save or print!

View 5 Repliesi would like to know if it's possible to save text files into my app. that way there is no folder to contain those files. i'm thinking that i might need a separate form to hold such information, like creating a new textbox for each saved file and it's content, then loading the files from that form's textboxes.

I have searched, but failed to find a suitable answer to this. My small app saves a text file using a savefiledialog and stream writer. Then if successful, displays a messagebox confirming sucess and asks if the user wants to open the text file now. and this is the problem... How do I determine if the user has changed the filename and or path in the savefiledialog when saving? I'd prefer not to hard code a path and file name if possible.... but that seems like the only option? and therefore I can't show the file straight after saving reliably??

View 11 RepliesThis is a new question based on the response from an older post. I needed to save a value when my app is run for the first time that would be applicable to all users who logon to the PC and use my application. The setting is only known at the time of the install so Application settings with application or user scope are unsuitable. I was advised to save the setting to an external file and save/read it as needed. The obvious choice was to save the file to the projects application path (keeping things tidy). Everything worked fine during testing but when the application is installed on a PC, the application path becomes C:program files application nameetc. When I try to execute the code that saves the file, I get a permissions denied error. I understand that it's part of the UAC control but when did it become acceptable to stop developers programmatically creating files in their own application folder?

I am currently writing a program in VB 2008. Here is what the program is intended to do: I need it to have two forms of input, so I want it to open existing text files and create new ones. Once the user has selected what input to be taken (either a file is opened or a new one is made, guessing multiple forms need to be used here) the user will then take the text file either created or opened and then be able to click a button which will sort all the text in the text file into alphabetical order and then display the results to the screen. While this happens, I need the words in the file to be counted by a counter (so a loop i guess) that then displays on which line each word appears on. I then need this information to be displayed in a text box on screen.
View 2 RepliesI'm trying to make a Doctor's program where the doctor has to enter the patients detail into several text boxes (Name, Age, Address...). So, after he has entered all the information, he would want to save it somehow so he could open up the information
again. How would i do that. I thought it could be saved in a database, or even in a text file.
i've been busy with a program and it has worked out quite well. The only thing I still want is that it is possible to customize things and save that in a text file. Normally if i want an other background for one day, i need to change it in VB or make a checkbox to do that. if i then restart the program all the settings are lost and i have to set it again. so i was wondering if the program can make a text file and put codes like 1 for theme 1 and 2 for theme 2 etc. in it, then save it and load that file when it starts up again. and is this also possible for a login form? if yes, i can also add a "Create Account" button for my program instead of adding codes in VB.
View 6 RepliesI want to save datetimepicker value of date and time in two separate text files. Currently, when I select a date from datetimepicker and save it in a text file it saves both date and time as below:
5/11/2011 8:25:06 PM What I would like to happen is as below: Datefile.txt saves 5/11/2011 Timefile.txt saves 8:25:06 PM Alternative solution that can work for me would be, if the time (only the TIME) can be modified after saving as below: saved datetime into text file is 5/11/2011 8:25:06 PM
How can I modify the time only to say 12:00:00 PM. By doing so I would like to keep time as 12:00:00 but date can be changed by the user using the datetime picker.
