How to make Shell() function synchronous ?

52 New Member
Hi everyone,
I am making using Shell() function to run a command line tool from my VB Application.

I am using it to archive a folder. So I am using the code :
Expand|Select|Wrap|Line Numbers
  1. Shell("command line argument as string")
  2.  
where "command line argument as string" is the DOS command for the particular command line zip tool.

The command is properly working but when the number of files are more in the folder, then the time taken to archive is more than some milliseconds or even more than some seconds.

Now the problem is that : I FTP this file to a FTP Server. But if the time taken to archive the folder is more then my execution of code reaches the FTP part and at that time it does not fine any .ZIP file in the specified location. Thus it fails to FTP the file.

One solution to this problem is to provide some delay after calling the Shell() function. But this does not provide a guaranteed time for all cases.

So I am searching for a way that I make this Shell() function synchronous (As it is Asynchronous by default, as they say in MSDN). In MSDN they say to include an Optional argument "True" to make it synchronous, but it is not working.

I am using VB6.

Please provide me with a way for this issue.

Thanks in advance

Thanks
But I found the ShellandWait code when I searched google for Shell + Wait. It solved my issue, the way I wanted.

Still looking for a unifying concept ;-) It struck me that @deco1 @deco2 def foo():pass uses '@' to register at-next-name-binding processing in a way similar to atexit's registering of processing to happen at ('@' ;-) exit.

Hi. I'm writing a command shell that reads commands from standard input. At this point I have the command in a std::string. Now I want to execute this command in the shell. From the Borland newsgroups I learned that there is a function in stdlib.h called system. int system(const char *command); First question, is the system command ANSI compliant. Because I include <cstdlib> and write std::system(command.c_str()); it looks like an...

Hi, It's seems that csh and tcsh acts a bit different when handling special characters in quotes. i.e: if i'll supply my program with the following arguments: -winpath "c:\\temp\\" tcsh will take it as -winpath "c:\temp\" and csh will take it literally (with the double-slashes). Is there a way for me to know what shell is currently running my

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
