 |
|
Hello
I try to use CreateProcess to launch an application built with BCB6 from my
application (also created with BCB6)
I use this code :
Tha called application's name is "Optitool"
//--------------------------
STARTUPINFO si;
PROCESS_INFORMATION pi;
ZeroMemory(&si,sizeof(si));
si.cb=sizeof(si);
ZeroMemory(&pi,sizeof(pi));
if(!CreateProcess(NULL,
TEXT("Optitool.exe"),
NULL,
NULL,
FALSE,
0,
NULL,
NULL,
&si,
&pi)
)
{ShowMessage("Process loupé"+AnsiString(
GetLastError()));
return;
}
WaitForSingleObject(pi.hProcess,INFINITE);
//-------------------------------------
I click the button calling the CreateProcess method (I have a break point
far away) I obtain the CPU window stopped on a line and at the caption of
wich there is error in "optitool.exe"
I clik the line on wich is the debugger to see the caller and obtain another
CPU window with only "??????????"
If I click the green run button of BCB6 (to execute) my optitool application
appears correctly an run well.
And when I close it My first application from wich I have called optitool is
always here running all is ok.
I don't understand why the CPR window appears
I have looked at the debugger options and checked "managed by debugger" at
SE exception and also for the go on check box.
I don't understand
I have looked at the microsoft's developper support for the use of
CreateProcess and the sample is the same.
I try to load other applications with it and it is the same thing
I don't understand
If you can help me please
Thank you in advance
Patrick

I have BCB 5, not 6. But I'll make a wild guess. There is a
check box under 'Debugger Options" that says "Debug spawned
processes". If it is checked, you'll break at the entry point to
Optitool with the CPU assembler/registers window open.
