I am working with MFC to read the file system and populate all directories, subdirectories and files in a tree. I am using a recursive function to do it. When this function finds a directory, it calls itself for searching that directory for its inner directories and files. I included objects of HTREEITEM as root and TVINSERTITEM as tvInsert in CFileSysDlg.
I wrote following code to populate the tree
int CFileSysDlg::FindFiles(HANDLE fp, unsigned long ino, unsigned long itable_blkno)<br />
{<br />
HTREEITEM newitem = root;
if (file_type == 2)
{<br />
tvInsert.hParent = root; <br />
tvInsert.hInsertAfter = NULL;<br />
tvInsert.item.mask = TVIF_TEXT;
tvInsert.item.pszText = (LPSTR)file_name;<br />
newitem = pCtrl->InsertItem(&tvInsert);<br />
FindFiles(fp, inodeno, itable_blkno); <br />
}<br />
else<br />
{<br />
if (file_type == 1)
{<br />
hPA = pCtrl->InsertItem(TVIF_TEXT,(LPSTR)file_name, 0, 0, 0, 0, 0,newitem, NULL);<br />
}<br />
}<br />
}
Problem is that it shows me directories and subdirectories at the same level.
Please tell me how can i correct it. Please reply me as soon as possible
Thanks

Hello Auueel.
The standard way to solve this problem is to use a variable which holds an "indent level number".
For every directory found, increment the "indent level number" variable. For every directory you back out of, decrement the "indent level number" variable.
Then use the "indent level number" variable when you display an item.

Hello
Mr. Kakan
I got your point but my problem is different. Check sample directory structure.
root
dir
innerdir
files of innerdir
..
..
but my program is showing parent of dir and innerdir as root while parent of innerdir is dir. How can i solve this problem.

Hello again.
I'm not familiar with the tree control, but as far as I know, you have to create the braches (and leafs) yourself, true?
If that´s the case, then the value of the indent level variable will tell you how many braches you have to create.
Or am I totally missing the point?
regards
Kakan

I have DLL library and .h file but it has been created in Borland
and i can not use its .lib file. And only thing, DLL exports is one class.
So I am lost.
Does somebody know how to do run-time dynamic linking for
such library - how to reach its class?
Or is there any way or program to create(generate) proper .lib for MSDEV,
just from DLL and H file?
Thankx lot

you can do Runtime Linking of A function.. For class it is not possible as you don't address of a function till your object of class is created

Hi,
I'm looking for ways to to paste Windows Clipboard content into MSHTML including images. I've come to the conclusion that using RTF from the Clipboard and converting that to HTML is the only sensible way to tackle this. Any other ideas most welcome.
So I'm looking for code to convert RTF to HTML. It must do images and support all of the most common RTF stuff. I prefer to get the source, but failing that a DLL would do.
I've googled and there are commercial components which are all pretty pricey, especially if you want source.
Suggestions, tips, pointers???

You could try these people[^]. They do a full RTF editor, and RTF to/from HTML conversion tools as well. We used a version of this in the past, and you can get source as well as a DLL. Still not cheap though.

Thanks Graham. I had come across that. As you say a bit pricey though. I use their SpellTime product in ED4W.

Hi,
I have a form view class derived from CFormView. In this class I have a thread which does some processing for every 30 seconds and generates a status message which is of type CString. I need to show this message in the Status Bar. From within the form view class I am calling a method names UpdateOnlineStatusMessage in the Frame Window class which updates the status bar.
void UpdateOnlineStatusMessage(CString strMsg)
{
PANEINFOEX pex;
pex.iIndex = 0;
pex.strText = strMsg;
pex.iFlags = SBP_ID | SBP_TEXT;
m_wndStatusBar.SetPaneInfoEx(&pex);
}
Here m_wndStatusBar member that represents the status bar in the FrameWindow calss. I am getting an assertion while trying to access m_wndStatusBar member.
Can anyone please help me to solve this.
Thanks
Madhavi.

Could you please show us! How do you connect the StatusBar member of MainFrame with m_wndStatus? i believe that the root cause of problem...
you can try this too ->
CMainFrame* pMain = (CMainFrame*)AfxGetMainWnd();
if(pMain)
{
PANEINFOEX pex;
pex.iIndex = 0;
pex.strText = strMsg;
pex.iFlags = SBP_ID | SBP_TEXT;
pMain->STATUSBAR_MEMBER-> or . SetPaneInfoEx(&pex);
}

The status bar is a member of mainfrme class itself and the function that updated the status bar is also in the main frame, so I use it directly. I'll call the function that updates the status bar from my form view calss

Are you using your custom CStatusBar Class. as i couldn't found SetPaneInfoEx and PANEINFOEX in My Local MSDN Copy (APril2004)!

In WinXP SP2, there is a service called "DCOM server process launcher" run via svchost.exe. Today I noticed in Process Explorer that there is a "iexplore.exe" process running as a child of this svchost.exe, and tracking back how I started this instance of Internet Explorer, I had clicked on "2 new email messages" in the MSN Messenger (6.2). This is very interesting and I dont know why internet explorer does not show up as a child process of MSN Messenger itself. Anyone any ideas?
I was curious, I then attached windbg to this svchost.exe and put a breakpoint on NtCreateProcessEx, and you know what, the breakpoint is hit even if I start IE from the Windows Explorer shortcuts. Infact, the breakpoint is hit for every process that I start from windows explorer. The difference, however, is that the process is still created as a child of explorer.exe and not as a child of svchost.exe when I start from Windows explorer.
The questions I have are:
1. How exactly does this DCOM server process launcher work?
2. How do you communicate with it to start a new process?
3. What decides on who is going to launch the new process? svchost or calling process?
I'm not sure if this is good forum to ask this question, if it is not and you know an alternate forum, please let me know.
thanks!

Hi All.
If I create a Panel, then we got a white line that distinguish your Menu and the Panel.
Now my question is, Can I get rid of this White line? If NOT then Can I change the color of this line to any other color?
Thanks and Best Regards.

CToolBar, and handle the WM_NCPAINT message in it, and practically do nothing in the function. Hence the white line will not be seen; instead, the window in the background will show, which is definitely not wanted.
You can:
Derive a class from CToolBar. e.g, "CMyTool". Handle its WM_NCPAINT message and do nothing in it.
Derive a class from CDialog. e.g, "CMyChildDialog". Give it child style, no border, no caption bar.
Create the toolbar as a child of the CMyChildDialog.
Then create a member variable of CMyChildDialog in CMainFrame, and handle CMainframe's OnSize() function to size the CMyChildDialog dialog to the top of the window, about 24 pixels height. You will also need to handle the toolbar button messages in the CMyChildDialog class, and route the messages to the right window.
Following the above difficult-to-follow guidelines, the white line can be removed.
But still the info you have given is not enough.
I created the toolbar dynamically using AddBitmap() and InsertButton() etc.
this is this.

I am sorry, I have never used wxWidgets before.
However, it could be that the child dialog has its border set to some weird color. As there are no panels in VC that I know of, so I don't think I can help more.
this is this.
