launching a program without black DOS box

[kahkaha]

I tried system("c:\\....exe") and ShellExecute("c:\....exe") but both of them shows a black DOS box.. I want do launch the program directly

[Mitsukai]

first this shuld be in win32 forum .
second the block box is from the exe?
third tried createproccess?

[kahkaha]

yes it is an exe file. How can I use createprocess?

[Mitsukai]

the black box is from the exe?

Pass DETACHED_PROCESS as dwCreationFlags in CreateProcess.

Don't forget to call CloseHandle on both PROCESS_INFORMATION::hProcess and PROCESS_INFORMATION::hThread

Or CREATE_NO_WINDOW as dwCreationFlags. Either way.

the black box is from the exe?

no. it is a windows application.

Maybe SW_HIDE in ShellExecute (not sure, didn't do Win API programming for some time).

I want to launch an application with path C:\Program Files\Firm Name\Program Name.exe. I think it does not work because path contains spaces

i tried system(c:\\program files\\firm name\\program name.exe);
also system(C:\\progra~1\firmna~1\progra~1.exe (not compiling));

Forgot ""? Also you should enclose it in "" in command line, to distinguish path to executable from its command line parameters, so it'll look this way:

system("\"C:\\Program Files\\Firm Name\\Program Name.exe\"");

(note \")

[kahkaha]

thank you it worked. also I found the total solution

to launch a windows program witout a black dos box, with parameters:

WinExec("C:\\Program Files\\My Application\\My App.exe C:\\foobar.tmp",SW_SHOWNORMAL)

It really works with spaces in directory names?

It really works with spaces in directory names?

Yep, that's a security flaw.
In order to avoid bugs written by bad programmers (especially Windows 3 programmers who assumed that most people don't put spaces in file names which was false, even in those early days), Windows first tries to search for a C:\Program.exe or C:\Program.com file, and if it doesn't exist, it tries C:\Program Files\My.exe (or .com), and then, C:\Program Files\My Application\My.exe (or .com), then, C:\Program Files\My Application\My App.exe. And, if it didn't exist, it would try C:\Program Files\My Application\My App.exe C:\foobar.tmp which is an invalid path, anyway.

This flaw can be exploited by malicious software.

One more example of "silently accept buggy input" strategy - though with such approach something sloppy is simplier to make work it tends to stay at that sloppy level.
