How to open a file and put its contents In a TextField?

Question

I'm trying to learn how to open a file, and put its contents in a TextField, using a Common Dialog, only a command dialog in Visual Basic 6.

I need this using a only a common dialog, because I'm trying to do the same application in eVB, and eVB does not support things like these, that makes the VB6 development more simple:

Dim objFSO As New Scripting.FileSystemObject
Dim objStream As Scripting.TextStream

Check out eVB File Access through the WinCE API. Sample code from the article (assuming you already got your filename (myFileName) from the Common Dialog):

Public Const GENERIC_READ As Int32 = &H80000000 
Public Const OPEN_EXISTING As Int32 = 3

' CreateFile will open a file handle (hFile) to the file in the myFileName variable
hFile = CreateFile(myFileName, GENERIC_READ, 0, 0, OPEN_EXISTING, 0, 0)

lFileSize = GetFileSize(hFile, 0)

' String(lFileSize, 0) will prepare the sContents string variable 
' to hold the contents of the file
sContents = String(lFileSize, 0)

' ReadFile actually reads the file we opened earlier and puts the contents
' into the sContents variable
ReadFile hFile, sContents, lFileSize, dwRead, 0

' Put the contents we read into the textbox
myTextBox.Text = sContents
