how do you call other programs from a c++ program? 1

[tchkid832]

hi, 1st year comp. si. student,

I just wrote a real simple c++ program from class. I wrote a perl script to prep the input file for my c program. Once the perl is converted to and exe how can I include it in the c++ program?

Do you want to "include" it like a library or "call" it from the C++ program?

I am the Unknown lead by the Unknowing.
I have done so much with so little
for so long that I am now qualified
to do anything with nothing.

I do not want to include it, I want to know how to call it.

Check out the ShellExecute function - windows.h -gerrygerry

#include <shellapi.hpp> //used with ShellExecute

void __fastcall TForm1::Image1Click(TObject *Sender)
{
char szPro1[160];
if(GetPrivateProfileString(&quot;BUTTON_1&quot;, &quot;1&quot;,
&quot;&quot;, szPro1, sizeof(szPro1), NewIniFile) > 2) {
char *s1 = szPro1;
fnsplit(s1,drive,dir,file1,ext);
char szDf1[160];
sprintf(szDf1, &quot;%s%s&quot;, drive, dir);
if(DirectoryExists(szPro1) == true) {
String S1;
S1 = ExtractShortPathName(szPro1);
ShellExecute(Form1->Handle, &quot;open&quot;, S1.c_str(), NULL, NULL, SW_SHOWNORMAL); }
else {
ShellExecute(Form1->Handle, &quot;open&quot;, szPro1, NULL, szDf1, SW_SHOWNORMAL); }
}
}

I hope this helps you to understand how the ShellExecute function is used.

Not quite what I was talking about but it should do the job! -gerrygerry

This works for me

HWND Switch;
Switch = FindWindow( NULL , &quot;Program_Window_Name_Here&quot; );
if ( Switch )
BringWindowToTop(Switch);
