[RESOLVED] Select all/Find/Open with?

I'm working on a program like notepad.

However, I will need to know the codes for the following actions:

1) Select all text in a textbox called txtTestFile

2) Find a certain word or phrase in the document and highlight it and make the textox scroll down to that part of the text

3) When I select a .txt/.vbs/.html document and make it open with my program, it just shows a blank text box. How do I make the text show?

Your help will be greatly appreciated

lngPos = prtbName.Find(pstrWord, 0)
 
Do
 
    blnRetry = False
     
    prtbName.SelColor = plngHighlightColor
    
    If pblnBold = True Then
        prtbName.SelBold = True
    End If
    
    lngPos = prtbName.Find(pstrWord, lngPos + prtbName.SelLength)
 
Loop While lngPos > 0
 
prtbName.SelStart = lngSelStart
prtbName.SelLength = lngSelLength
 
End Sub
 
Private Sub Command1_Click()
If chkBold = vbChecked Then
    ColorWord RichTextBox1, Text1.Text, vbRed, True

How are you selecting and showing it?

This says to me that you are already at the point where you are selecting a file and attempting to read it into your richtextbox.

This is a pretty simple task, so if it is just showing a blank, I'd like to know how you are selecting it, and, after selection, how you are reading it into your textbox.

Hack, I think he is asking how to associate file extensions with his program. Also, I think he means highlight as in select not highlight as in color it.

I am opening it through windows using "open with". otherwise, I open them using my "open" button (in my program) using this code

VB Code:

Private Sub openmenu_Click()
 
    Dim strBuffer       As String
    Dim intDemoFileNbr  As Integer
    Dim strFileToOpen   As String
    
    On Error GoTo openmenu_Click_Exit
 
    With dlgDemo
        .CancelError = True
        .InitDir = mstrLastDir
        .Flags = cdlOFNHideReadOnly
        .FileName = ""
        .Filter = "Text Files(*.txt)|*.txt|All Files(*.*)|*.*"
        .ShowOpen
        strFileToOpen = .FileName
    End With
  
    On Error GoTo openmenu_Click_Error
    
    intDemoFileNbr = FreeFile
    Open strFileToOpen For Binary Access Read As #intDemoFileNbr
    strBuffer = Input(LOF(intDemoFileNbr), intDemoFileNbr)
    txtTestFile.Text = strBuffer
    Close #intDemoFileNbr
 
    mstrLastDir = Left$(strFileToOpen, InStrRev(strFileToOpen, "\") - 1)
 
    Exit Sub
    
openmenu_Click_Error:
    MsgBox "The following error has occurred:" & vbNewLine _
         & "Err # " & Err.Number & " - " & Err.Description, _
           vbCritical, _
           "Open Error"
           
openmenu_Click_Exit:
End Sub

however, It refuses to open if I open it through windows

ajames, use the second link I posted above to get it to open through windows. If you have trouble implementing that code, post here and we will help you.

I cannot access the registry to do this.

If you are creating a Notepad like program why are you opening a text file for Binary Access Read?

If you are going to read a text file into a textbox you should be opening the file for Input.

I'm not sure what you are talking about, but this is what i mean:

If I open a file IN my program (using my code above) it works fine. HOWEVER if I want to open them from OUTSIDE the program, it does not work.

Please put some kind of code, I don't understand lots of this technical jargon

Opening a text file for binary is just another way of opening things. It tends to be faster. You get the same result.

To get openwith to work you have to load the file that is in Command$ when the program starts. For example:

VB Code:

Private Sub Form_Load()
    Dim strBuffer       As String
    Dim intDemoFileNbr  As Integer
    Dim strFileToOpen   As String
    If Len(Command$) > 0 Then
        intDemoFileNbr = FreeFile
        Open Command$ For Binary Access Read As #intDemoFileNbr
        strBuffer = Input(LOF(intDemoFileNbr), intDemoFileNbr)
        txtTestFile.Text = strBuffer
        Close #intDemoFileNbr
        mstrLastDir = Left$(strFileToOpen, InStrRev(strFileToOpen, "\") - 1)
    End If
End Sub

These may seem like similar tasks but they are actually quite different.

You MUST access the registery to have .txt or .html files automatically open with your program. The link I posted earlier in this thread teaches you how. Have you read it? If you don't understand it then ask questions, but at least try to read it.

The way it works is like so:
* You double-click a .txt file in Windows
* Windows looks in the registery to see what program it should open this type of file with
* It then executes that program using the command line. This means that things are passed to your program via the command line (like the DOS).
* When your program is run this way, the command line will hold the path of the file that called it. You have to get that path and then use it to open the file you want.

I do not wish for it to AUTOMATICALLY open those type of files. Just for it to open a certain file type once using the "open with" button on windows.

Also, neither "find" commands worked.

And did you try my suggestion? This is how it is done when you select Open With and Browse for a program.

In that case then you don't need to access the registry. but you do need to what moeur said (and what I mentioned). You need to parse the string held in the "Command". That is the only way your program will know what is going on. How else would it know which file to open?

Here is how the process works
* Go to "Open With > Browse..." and select your EXE.
* Windows executes your program using a DOS command that would look something like this: "C:\dev\VB\Projects\test project 2\main.exe C:\My Documents\myfile.txt" (that isn't exactly how itlooks like, but its something like that).
* You can then use the string held in Command in VB to get the path of that file and open it.

Do you understand now?

You didn't say you were using a RichTextbox so heres the code for a normal Textbox.

VB Code:

Dim nPos As Long, nPos2 As Long
 
Const PHRASE As String = "Waddup"
 
With txtTestFile
    nPos = InStr(1, .Text, PHRASE)
    If (nPos) Then
        nPos2 = InStr(nPos, .Text, " ")
        .SelStart = nPos
        If (nPos2) Then
            .SelLength = nPos2 - nPos
          Else
            .SelLength = Len(.Text) - nPos
        End If
    End If
End With

Right, we're getting there. Penagate's find command works, except for two things, the line
".SelStart = nPos" needed to be ".SelStart = nPos-1"
and the line
".SelLength = Len(.Text) - nPos" needed to be ".SelLength = Len(.Text) - nPos + 1"

But moeur's open with command came up with an error like "Error 53 : Bad command or file name".

okeydokey,

do you start in Sub Main(), or in a Form_Load()? If it is the latter, I suggest you make your startup object Sub Main (Project menu -> Properties).

Then, you can parse the return value of Command$() in there.

VB Code:

' In a .bas module
 
Private Declare Function PathFileExists Lib "shlwapi.dll" Alias "PathFileExistsW" ( _
    ByVal pszPath As Long _
) As Long
 
Private Sub Main()
Dim sFilename As String
Dim sBuffer As String, hFile As Long
    sFilename = Trim$(Command$())
 
    Load <MainFormName>
 
    If (PathFileExists(StrPtr(sFileName)) = 1) Then
        hFile = FreeFile()
        Open sFilename For Binary Lock Write As #hFile
        sBuffer = Space$(LOF(hFile))
        Get #hFile, , sBuffer
        Close #hFile
 
        <MainFormName>.txtTestFile.Text = sBuffer
    End If
 
    <MainFormName.Show
End Sub

That should work.

On what line of code did you get this error?

Penagate's one doesn't come up with errors but the text box is still blank when I open a file through windows

Before the Load <MainForm> line, put this line in

VB Code:

MsgBox sFileName

and post what it says when you use Open With.

It says nothing

That's impossible, as long as you definitely selected the file and chose to "Open With" and navigated to the latest build of your application. Windows will pass the path of the file as a parameter, which will turn up in the result of the Command() function.

aha, it now shows "C:/Documents and Settings/All User/My Documents/test.txt", but when i press "OK" there is nothing in the textbox

Is there text in the file?

(I'm not being funny, it's happened before... :))

Yep. About three sentences

Can anyone help?

This does work

VB Code:

Private Sub Form_Load()
    Dim strBuffer       As String
    Dim intDemoFileNbr  As Integer
    Dim strFileToOpen   As String
    strFileToOpen = Trim(Replace(Command$, Chr(34), " "))
    If Len(strFileToOpen) > 0 Then
        intDemoFileNbr = FreeFile
        Open strFileToOpen For Binary Access Read As #intDemoFileNbr
        strBuffer = Input(LOF(intDemoFileNbr), intDemoFileNbr)
        txtTestFile.Text = strBuffer
        Close #intDemoFileNbr
    End If
End Sub

I'll also attached the project

Thanks! It works!
I cannot see why the other ones didn't work. Anyway, that's it, thanks you everyone for all your additions, especially the one's that work
