Re: Possible to organize the ClassView in Visual Studio…?

Right-click the project, select New Folder. Name the folder. Start dropping classes into it.

In VS 6.0, the folder structure is stored entirely in the workspace .opt file (.vco if you're using eMbedded Visual C++).

Visual Studio .NET's folder structure exactly matches the on-disk structure. You can't create folders in Class View, but you can create folders in the Solution Explorer. The Class View can be organised by namespace; it represents the logical, not the physical, view of the code. Often it's a good idea to match namespaces and disk folders.

Stability. What an interesting concept. -- Chris Maunder

Ehm, the USB connectors can usually be found at the backside of your computer. They're small rectangular connectors.
If your computer is not equipped with these, it's massively outdated. A remedy is a plugin PCI-USB controller.

If that's not the answer you've hoped for: be more specific when attempting to formulate a question.
What do you want to do by what means?

If you are using winXP or 2000 you are going to have to use a kernal mode driver to do the middle man work. I suggest you get a Cypress EZ USB board to learn on.

Running a Batch file Froma a Program

sweep12312-Jul-04 0:48

12-Jul-04 0:48

Have I got this scheme right for running a scripting batch file from my program.

The program that is associated with the batch file is CSL.EXE and the following procedure will run when the selected TreeView file is double clicked:-

void CScriptingDlg::OnNMDblclkTree1(NMHDR *pNMHDR, LRESULT *pResult)<br />
{<br />
   BOOL bSuccess = FALSE;<br />
    SHELLEXECUTEINFO sei;<br />
    ZeroMemory(&sei,sizeof(sei));<br />
    sei.cbSize = sizeof(sei);<br />
    sei.hwnd = AfxGetMainWnd()->GetSafeHwnd();<br />
    sei.nShow = SW_SHOW;<br />
    sei.lpFile = m_strPath.GetBuffer(m_strPath.GetLength());<br />
    sei.fMask  = SEE_MASK_INVOKEIDLIST;<br />
    bSuccess = ShellExecuteEx(&sei);<br />
    m_strPath.ReleaseBuffer();<br />
}

m_strPath is the full path name of the batch file; e.g. C:\Work\ABC.CSL.

The reason for this post is, if I double click a CSL batch file (i.e. C:\Work\ABC.CSL) from Window Explorer the CSL program runs OK, but if I do the same from within my program a DOS Window appears for a second then closes. The batch files appears not to have run.
So is this the correct way to do this?

Per MSDN:

The lpIDList member must point to an ITEMIDLIST structure.

What is the value of bSuccess? If it is FALSE, what does GetLastError() return?

The code was lifted from the FileTreeCtrl sample on the code project site.

http://www.codeproject.com/wtl/wtlfiletreectrl.asp

When I place a breakpoint at the statement:-

m_strPath.ReleaseBuffer();

The bool is 1 and last error is zero.

Both this sample and my version are able to run up Notepad when double-click on a txt file. An image editor will run up for bitmaps.

But neither runs the CSL program associated with the ABC.CSL file.

While I doubt it's related to the problem at all, the calls to GetBuffer() and ReleaseBuffer() are not necessary.

What value are you assigning to lpVerb?

If I use

sei.lpVerb = "open";

then the files is opened with QuickView and that includes .txt and .log files.

The code does not generate any erros, just dont seem to be able to run the program CSL.EXE in the correct manner with this code.

As I said if I use Windows Explorer then the CSL.EXE runs OK with the selected file.

Any ideas?

My question may seem a bit lame. But I always twist my mind when trying to start a new project; i always have projects as they try to help me learn more.
But it takes me some time to come up with one, itried seaching the net for sites which offer list of project titles as a start point for fellows like me who waste their time wondering what to do ??
So pls if u know a site of this kind or have a list of possible ideas tell me.
Now i am finished with the project i was developing
"Digital Power System Simulation" and now ready to another??????/

Is this to run on a Windows For Workgroups machine? If so, you'll be needing a 16-bit solution. Dead | X|

Otherwise, if the machine is NT-based, check out ReadDirectoryChangesW() and FindFirstChangeNotification().

Asynch Serial Comms

Hi there,
Is there any other way of implementing asynchronous serial communication in Visual C++ than the MFC way. The MFC way is too time consuming.
I so far have seen that _inp and _outp are only for WIN95 platform.

Any suggestions will help.

Thanks.

You can use CreateFile and the Win32 Communications API which contains functions like BuildCommDCB(...) etc.

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