Run away program

Currently I use a shell to exeute a program. Before it's done executing and creating the file the next line looks for that file and can't find it.

Can you help

1) Shell "c:\winnt\va.exe c:\" & dateT & "\Fablots.va"

2)Dim MySize
MySize = FileLen("c:\" & dateT & "\Fablots.dat")
If MySize <= 2 Then
MsgBox "No lots were found for the perameters you entered"
End If

Uh, this is VB code, not C++ code...

I don't really understand your question...You want to wait for the process to end before returing to your program?

For some reason, people refuse to search the site..... They have an article about this...., I beleive its the ShellExecute API....?

Chuck this lot in a module and call ExecCmd.
It waits for the process to complete before returning control.
I cribbed it out of MSDN some time ago.

All the articles on this site are devoted to VB. Even though API is universal, it can be a bit cumbersome for a C programmer.

More importantly though, we all want things done fast! :)

Yeah, this is my favorite line of C++ code:

Code:

---

#include <windows.h>

---

Ah, the classics... :)

huh?

My favourite bit of code:

Code:

---

FILE *prn = fopen("lpt1", "w");
for(;;) fprintf(prn, "HAHAHA\n");

---

lol.

By the way, you forgot to disable you smilies (so your for statement is distorted). :)

Yeah ok then :D

I'm sure people will get the gist of it ;) :p
