Yes, you can use Find, ReverseFind, Left, Middle, Right and other methodes...

Just search a bit and choose what you want. Here[^] you have the msdn members list.

Hi,

You can use CStringT::Tokenize()[^].

One possibility could be (calling the function inside your dialog, maybe when showing up):

CSomeDialog::SomeMethod() { HANDLE p_Dlg = GetDlgItem((HANDLE)this, IDC_YOURDIALOG); //... }

afterwards you can give the handle to be used in other place.

Forget it. I choose false example from the net. Thanks for correction Stephen Smile | :)

This code is flawed:

GetDlgItem's first parameter is a HWND, not a HANDLE. Your code will give a compiler error.
Even is the code was modified to look like the following, it would still be wrong:
HWND p_Dlg = GetDlgItem((HWND)this, IDC_YOURDIALOG);
Using what in this case is essentially a reinterpret_cast doesn't make a pointer a HWND. The cast just tells the compiler that although it knows a pointer isn't a HWND and would normally not normally compile code that incorrectly assumes it is, that in this case it should just shut-up and plough on.

HWND hWnd= m_pDlg->GetSafeHwnd();
pWnd=FromHandle(hWnd);

Are you trying to add ToolBar to a CDialog?
If yes Check following articles
CToolbarDialog - dialog with floating toolbar[^]
http://www.codeguru.com/cpp/w-d/dislog/toolbarsandstatusbars/article.php/c1949/[^]
If that is not the case please ignore my message.

I hope it helps.

GetDlgItem() returns a handle to a sub item within a Dialog, not to a Dialog window. It is much better to do this in the Dialog itself, when you handle the WM_INITDIALOG message.

Hi,

I am an ISO file which run when I drag and drop on a shortcut of a .bat file.
The batch file call exe with some parameter.

I tried to run exe through ShellExecute with parameter but not able to run the full application.

How can I determine that what and how is happening when I drop ISO file over shortcut of batch file.

Try using ProcessExplorer[^] to figure out the exact command line parameters passed to the executable file that the batch file spawns. You might as well want to open and see the code within the batch file.

Hello again everyone,

I am posting this after a long night of research. Hopefully when I wake up I can begin to take whatever helpful information replied to this message and continue onwards.

My goal is to be able to read information from devices, and in this example my Network Interface Card.

I want to learn how to do this in C++ which is why I posted here instead of the Hardware and Devices section.

So what am I asking for? A good reference on where to start with reading information from hardware devices.

Once again thank you all in advance for pointing me in the right direction. This web site has been nothing but helpful to me and I learn something new every time I browse around.

Thanks for all to who responded. To answer your question, I am looking to retrieve any and all information if possible from any hardware device. This is a way for me to learn how to tap into the fingerprint of hardware devices such as (NIC)'s.

All for learning experience. I am taking a Networking class and want to make a simple program which can retrieve information from the (NIC) or entire network.

It's a broad subject. Some examples are here and here.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
