hello, i want you help, how can i let a windows gui program run in background, don't tell me use ShowWindow(SW_HIDE), i have tried that one, it's not a good method.
There's such a function, SetForegroundWindow(), can i use SetBackgourndWindow...
And several monthes ago, when i telnet to another pc, and run Notepad.exe in that computer, i found Notepad.exe is really in that computer's background, i want that effect also, can anybody help me.
Thanks very much.

Have a look at the BackgroundWorker class. That should be what you need.

thanks, but seems this one belongs to other vb.net, or C#

I hope a standard win32 api or such functions, not such a component.
But thanks for your help.

You could launch a GUI app from a windows service application using CreateProcess().
I suppose the telnet session did that with notepad.

Edit: Also you could use ShowWindow(SW_HIDE) Big Grin | :-D

What exactly do you mean by this? Unlike Unix, Windows does not have the capability to run processes in the background. They are either running or they are not. A window's Z-order has no bearing on whether its process is running or not.

You'll need to recompile it.

I doubt there is a simple solution, I'd be looking at sourceforge or something.

I need to develop simple code to print the contents of a directory and the contents of all sub directories. The files to be printed will be selected according to a user defined extension. Which library and commands will be most useful?

i guess the Boost filesystem library will suit me, but am still unsure how to sort files by extension

you can use of FindFirstFile/FindNext for read files but what do you need exactly?

FindFirstFile will not help me. i need to navigate through a filesystem and print the contents of each directory to the screen, counting the number of directories in each level.

Do you have any idea for read them?

I've installed VS2005, but some of my projects can't be compiled to
debug version, the program will fail on "can't find msvcr80.dll"
message, when launched. However, the release version is ok. And
also some projects can run debug version correctly.

I know 'can't find msvcr80.dll' problem exists on system without .NET framework installed, but that's not my case.

Does anyone know the probably cause???

parameter 2 of GetDlgItemText must be CString, but these you use are not.

GetDlgItemText(IDC_EDIT1,m_TQuote.m_DateTimeStamp);
~~~~~~~~~~~~~~~~~~~~~~~~~
GetDlgItemText(IDC_EDIT1,m_TQuote.m_MarketNo);
~~~~~~~~~~~~~~~~~~~~
GetDlgItemText(IDC_EDIT1,m_TQuote.m_Bid);
~~~~~~~~~~~~~~
GetDlgItemText(IDC_EDIT1,m_TQuote.m_MarketName);
~~~~~~~~~~~~~~~~~~~~~
GetDlgItemText(IDC_EDIT1,m_TQuote.m_Ask);
~~~~~~~~~~~~~~
GetDlgItemText(IDC_EDIT1,m_TQuote.m_MarketState);

change the table or convert the data type to CString first.
