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.

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??????/

Well when I want an idea of something to develop, I hit sites like download.com and other shareware sites and that usual gives me some inspiration. Of course there are places like http://www.rentacoder.com[^] which have hundreds of project ideas.

Hi,
How to trap file reading and writing in Shared Folder over a Network for Workgroups in Windows? Further more, may I trap browsing event in Shared Folder?
Thanks.
|
|
|
|
|
Is this to run on a Windows For Workgroups machine? If so, you'll be needing a 16-bit solution. 
Otherwise, if the machine is NT-based, check out ReadDirectoryChangesW() and FindFirstChangeNotification().

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.
|
|
|
|
|
Thanks for the reply.
Yes, you're right CreateFile() and the WIN32 Comms API can be used.
My problem is that I receive data that is between 40 and 45 bytes in length far too late. The instrument on the other side sends the data at 9600 baud every 100ms. My program must receive it by 65ms.
At the moment the data is received it at approximately 80ms, which is way too late. I have used the CreateFile() and ReadFile() with the necessary time-out, threads and event operations to read the data.
I also wrote a utility in Delphi which seem to work fine (54ms). Unfortunately the code must be in C++ as it fits into a bigger Visual C++ program.
Any ideas.
Thank again.

My application have to offer a dialog to select a file to be deleted.
I've tought to CFileDialog but it is useful only to open or to save a file.
Is there a way to have a dialog to browse files in order to select a file to be deleted ?
Thank you very much !
|
|
|
|
|
You can just use CFileDialog to select the file, by just display the "Open" dialog and with the filter flags OFN_HIDEREADONLY | OFN_FILEMUSTEXIST and just change the title of the dialog (I think there is a member function to do that) or that a look at m_ofn member data.
|
|
|
|
|
You can still use a File Open dialog to ask for a file name to be deleted; you'll need to change the title and the caption on the action button to Delete.
To change the title, set the m_ofn.lpstrTitle member. Changing the action button's caption is harder: I think you'll have to create a hook procedure which handles WM_INITDIALOG; in the handler, call SetWindowText for the button with the IDOK control ID (which you can get with GetDlgItem).
Stability. What an interesting concept. -- Chris Maunder

I would use CFileDialog to select the file, show the path in an editbox and let the user press delete.
This way the user can rethink his/her decision.
so my advice would be:browse button to select (show path in editbox)
delete button for the obvious action of deleting the selected file;)
MessageBox to confirm.
hope it helps.

here your solution->
Use this little Piece of code
CFileDialog a(TRUE);
a.DoModol();<br />
CString sr=a.GetPathName();<br />
::Unlink(sr);
