text into sub?

Hi everyone,

this is a bit of a strange question and I don't think you can do it, but I thought I'd ask anyway.

say you have a text file which contains vb code, is there anyway to say import that text file into your program to say turn it into a sub?

for example say you had a sub called lets say crypto

sub crypto

end sub

and that was all we had for the particular sub, now the text file we have, has the following code in it lets say:

dim crypt as string
dim cryp as string

cryp = text2.text
crypt = instr(1,cryp,"blah",vbTextCompare)

if crypt <>0 then

'more stuff here etc

end sub

now is there anyway to make the sub crypto imports that information???

thanx for any help.

Why not just copy and paste?

I'm not sure but I think he means during runtime.

no, I think you can do it in Java though.

Yeah I mean at run time, I didn't think you could, it was just that my program gets data from a webpage, and if the webpages changes certain things in their layout and things then the way I get the data is invalid, and I have to make a new build sort of thing, I was just thinking instead of that maybe I could upload a text file to my site containg the latest code for extracting the code, and then download the text with the inet control, and import it into that sub, instead of having to keep making new builds sort of thing.

thanx for replying.

There are compiler issues trying to do what you've asked in VB alone, but a VB-VBA approach may work. Make sure your References include "Microsoft Visual Basic for Applications Extensibility"

For demo sake, say you have textfile named mystuff.txt in c:\tmp that has:
Attribute VB_Name = "Module10"
Public Function Gee()
MsgBox "hello world"
End Function

Now in VB:

Private Sub JamCodeByWayOfOmaha_VBA()
Dim xlapp As Object 'Excel.Application
Dim xlbook As Object 'Excel.Workbook
Dim xlmodule As Object 'VBComponents
Dim xlmodule2 As Object
Dim strCode As String
' Start Excel
Set xlapp = CreateObject("Excel.Application")
xlapp.Visible = false ' value may have to be true, I'm winging this.
' Add new workbook
Set xlbook = xlapp.Workbooks.Add
' Add a module
Set xlmodule = xlbook.VBProject.VBComponents.Add(vbext_ct_StdModule)
' Add text by line to a macro in module
strCode = "sub MyMysteryMac()" & vbCr & _
" msgbox ""Hmm."" " & vbCr & "end sub"
xlmodule.CodeModule.AddFromString strCode
' or save some grief and import from textfile
Set xlmodule2 = xlbook.VBProject.VBComponents
xlmodule2.Import "c:\tmp\mystuff.txt"
' Run macros
xlapp.Run "MyMysteryMacro"
xlapp.Run "Gee"
' Pause to pat self on back and watch purists' heads explode...
MsgBox "All done, click to continue...", vbMsgBoxSetForeground
' Release modules & clean up
Set xlmodule = Nothing: Set xlmodule2 = Nothing
xlbook.Saved = false
xlapp.Quit
Set xlbook = Nothing: Set xlapp = Nothing
End Sub

Hope this helps.

Thanx Mongo, I really didn't think that it was possible, I thought it was a bit stupid me even asking that question, great code.

But is there anyway to say put the function into a module you already have in your .exe? or make a module at run time in the exe and put the code in that sort of thing so that you can run the function in the module along side your form so you can send things to the form?

thanx again.

At runtime there's plenty of deadwood space in a VB exe where you can write characters, but no, to my pea-brain knowledge, you cannot add function/sub functionality via a pre-post-compile methodology. You could expand the example I gave to store values on a worksheet and then read them from you VB app for use on a form or whatever.
