I have RTB witch I can edit with text by using .
RichTextBox1.text = RichTextBox1.text & "stuff" & VbcrLf
Great but I loose any editing to colour/font I may of done previously. Is there a way of just adding a new line. I am thinking along the lines of finding the last character then adding my new line.
I want to loop the lines of my RTB and add a vbTab on each line.How do i do this?

View 4 RepliesI have a program that reads a text file tab delimted using OLEDb I need to be able to allow the user to insert a user created record into the file which I can do. The problem is I need to be able to let the user edit that record. From my understanding you can not edit or delete with OLEDB only insert So I thought I would read the file using stream reader, find the line I want to edit and just delete it, rewrite the file, then let the user insert a new record?

I am loading a listbox with lines from a txt file. Now I would like to be able to edit values within that listbox by going there with the mouse cursor and type a new value..
E.g. the listbox displays:
7226218; Hemlock; 22.55; 4
0822722; Pine, Sugar; 11.55; 7
After editing it looks like:
7226218; Hemlock; 22.55; 2
0822722; Pine, Sugar; 11.55; 7
After pressing an "accept button" those values should then be written back to the txt file.
I am trying to speed up the process of changing flags within an INI file used for a program. Ideally i want a simple form with ON/OFF radio buttons which are specific to different options within the ini file. For example, if i wanted to turn Printing off in the ini file, i could select OFF for which this will edit the ini file and change the setting "Printer=0"

Dim file As System.IO.File
Dim reader As System.IO.StreamReader
Dim line As String

Ok so i have a uni assignment to delete lines of text out of a text file, so far i have figured out how to search the text file for specific bits of text, i,e name of user, ive also used a loop to find out what line in the text file the specific line exists as...my
code so far is
Dim line As String
Dim Input As StreamReader
[code]....
the selected policy is what im tryin to use to write over the line of texts that already exists however i think that maybe instead of deleteting what exists it will just move it down a line and make a blank line
I am trying to make the code edit the a line in a text file, but it ends up deleting all the text and add the line at the begging of the file.

View 1 RepliesI have a multiline textbox from which I would like to read each individual line and store it in an array. I don't want to store each carriage return, I want the line itself.I have been using this, but it only records lines followed by carriage returns.
Dim arra() = txtReceipt.Text.Split(Environment.NewLine)
Here is a visual example: [URL]From that top right textbox, I would want arra(0) to be "Type some stuff here (and hit the return and" and arra(1) to be "tab keys...)"
When in "Add" mode, I have all controls on the form enabled with the exception of a listview that is disabled until the record is saved. The listview needs the primary key from the saved record in order for items to be added to the listview.
When in "Edit" mode, the form is populated when a record is selected on a search form. Specific controls are disabled. When a value in a control is changed, I have a RecordModified property that is set to True and then the Save button is enabled. I also have combo boxes that need to be populated but the selected value needs to correspond to the value pulled from the database
I'm trying to edit my sql database using VB Forms.I went ahead and connected my database to VB and I see how to pull data from my database to VB, but I'm not understnading how to use a form to add/edit/delete data from the database.Basically I would be looking to add to a table:
Table Name: People
Row 1: First Name
Row 2: Last Name
Edit would be the same type of thing except I think I would pull the data from the database to populate a table, than how would I save the changes after I changed the information To delete I'm assuming would be similar to edit I would simply pull the data from the database than using a delete button would delete it.What I don't understand is how to create the SQL statement in VB so that it'll execute it properly in my database.
I was playing a game recently and saw that they could use args in the shortcut, and I decided to try to impliment this into my application...so far, I got: (runs this sub on load)

Dim path As Array = Environment.GetCommandLineArgs

just to see what it returns, but the application crashes. I also tried path.tostring(), but that didn't work. When I did:
If Evnironment.GetCommandLineArgs.Contains("+game") Then
Dim path as string = Environment.GetCommandLineArgs.tostring
MsgBox(path)

but that returned the value "SString.Array[]"...

I am needing to write to a "rtf" file, and always insert my text on line 3 of either a new or an existing rtf document.I'm familiar with vb, but have not done much with the system.io functions. I have been testing several examples from the internet using the streamreader and streamwriter but still having issues finding a way to "insert text" on a specified line number. My questions:
1)I will always need to write on line #3, do I need to read all lines as this example shows "lines.AddRange(System.IO.File.ReadAllLines("C :/test/myrtffile.rtf"))"

I am busy with a project converting VS2005/2008 sln files.
I am quite far but have came acroos a problem with my source code.
I have found the files I need to change, I have changed them to the version that I need.
I now need to read the files back into my program and delete the line I have changed as it contains project numbers that are irrelevant. Then I need to save it.
I have got as far where I have searched for lines that begin with 'Project'. I have changed this also so it's now a question of reading the files in, Deleting the line with the 'Project' number and saving them.

I am working on an application and I want the user to be able to enter commands into a textbox, and when they press enter, the command is printed in a rich text box, executed, and the output is printed. For instance: the user types move{file1}, {location} into the text box and this happens:
>command: move{file1}, {location}
>$ moving file1 to location
>job completed
How would I write lines to the rtb and execute commands when the enter key is pressed?
This works, partly.
Private Sub TextBox1_KeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles command.KeyPress
If e.KeyChar = Microsoft.VisualBasic.ChrW(Keys.Return) Then
RichTextBox2.Text = Environment.NewLine + command.Text
End If
End Sub
it erases everything in the textbox before adding the line... I would also like to be able to make a database of commands, maybe a .dll or something, so that when the user types in something, it checks that database to see if the command exists, if it does it executes, if not, error.
I am working in VB. I have a fairly long and detailed explanation that I'll avoid posting but what I'm looking to find is quite simple. I'm looking for information how the command line executable LAME.EXE (the Mp3 encoder) returns information to the host program/form.
I am a VB novice and a novice to programming in general and am looking to learn more about as much as I can on the whole but basically I have a Windows form that gathers all the necessary information as a front-end:
The input .wav file path
The output .mp3 file destination
The encode settings (bitrate, frequency, etc)This information is pooled in to a string like this: lame.exe -v -b 112 input.wav output.mp3 or any variant on the settings selected in the GUI which is then in turn used to execute LAME.EXE with the set of parameters in a command line console...That's all well and good and it is quite functional but what I'm looking to do is to 'hide' the console in itself and have the encoder feed back its progress, say as a percentage inside the GUI.
The problem is that it doesn't appear that LAME in itself has this kind of functionality explicitly built in. I know it's possible however, as every single front end in the world has this functionality.I have tried a few ways of doing this with avoiding the issue of not being able to find the functionality within the codec. Perhaps I'm looking in the wrong place entirely or I'm not thinking correctly 'outside the box' as it were.
what I'm looking for is to use a command like this within the script itself: lame(v,b,112,"C:input.wav","c:output.mp3") or even pass the parameters obtained from the GUI a string formatted dynamically on the fly itself.I expect of course that this kind of functionality won't be available anywhere at all, what I'm really looking for as a workaround that reports the actions/progress/console output of the executable back in to the VB program somehow.
Private Sub StreamInput(ByVal Text As String) m_Process.StandardInput.WriteLine(Text)

I am writing an application in which a user is doing a file conversion. I have a set of tools that can perform the conversion on the fly via command line, but I'm not entirely sure of how to go about passing the parameters I need to the command line and running them. Can someone point me to the right direction?Would I just create a System.Diagnostics.Process and use that? If so how do I do the line by line command? For instance if I need to issue a cd command to change the directory and then execute a command after that how would I do that?
View 1 RepliesI'm creating a GroupBox at runtime and setting its Text property. Usually, the text is only on one line, but sometimes it wraps. The problem is that the controls contained in the GroupBox cover up the GroupBox's text.
What I'd like to do is determine if and when the text wraps. Specifically, I'd like to determine how much extra height the wrapped text takes up as compared to a single line. That way, I can reposition the GroupBox's controls and adjust its height.
Initially, I thought I'd do this by calling the GroupBox's CreateGraphics() method, and using the Graphics to measure the string. Something like this:
[Code]...
The problem is that the size generated by g.MeasureString(text, grp.Font) doesn't seem to be accurate. I determined that it wasn't accurate by putting enough of a single character to cause a wrap, then measuring the resulting string.
For example, it took 86 pipes (|) to until a wrap happened. When I measured that string, its width was ~253. And it took 16 capital W's to force a wrap - its string had a width of ~164. These were the two extremes that I tested. My GroupBox's width was 189. (a's took 29 and had a width of ~180, O's took 22 and had a width of ~189)
What this line means? Inherits System.Windows.Forms.Form
