<H1>Subject: Embedding GN-Tools in Visual BASIC 5.0
</h1><pre>From: "Open Mind Productions" <openmind@bigfoot.com>
A while ago I promised to send you the code to embed your tools in Visual
BASIC.
Well, here it is !
As an example I use MIDINOTE, but it should work with all DOS executables.
--------------------------------------------------------------------
' Change the work directory to the application directory
' midinote.exe should be located there !
ChDir App.Path
' Copy the original midi-file to the work-file "temp.mid"
' This solves the long filename problem for DOS
FileCopy lblFileName.Caption, App.Path & "\temp.mid"
' Create a batch file to run midinote.exe
Open App.Path & "\PlugIn.bat" For Output As #1
Print #1, "midinote -values temp.mid > output.tmp"
Print #1, "copy output.tmp 0.tmp"
Close #1
' Run the PlugIn batch file
runPlugin = Shell(App.Path & "\PlugIn.bat", vbHide)
' Make the Visual BASIC application wait for "0.tmp" to be created.
' This means that the batch file has finished and "output.tmp" has been
created.
On Error GoTo plugInWait
plugInReady:
Open App.Path & "\0.tmp" For Input As #1
Line Input #1, xx1
Close #1
Kill App.Path & "\0.tmp"
Kill App.Path & "\temp.mid"
GoTo startProcessing
plugInWait:
Close #1
Resume plugInReady
startProcessing:
' This is where you can put code to process "output.tmp"
...
...
...
...
' Erase "output.tmp" when it's not needed anymore
Kill App.Path & "output.tmp"
--------------------------------------------------------------------
This code can be copied directly into a VB application.
I hope the embedded comment lines will do.
Thanks for your great C++ apps !!
Alex
