In VC6, you will find it here:
Goto Project->Settings->C/C++->Preprocessor.
Put them in "Additional include directories:"
If you want more than one, separate the with commas.

Please Guide

Hello.
I feel I must respond, since noone else does. Smile | :)

I'm not in any way DB expert, but I have a faint memory that a real expert once told me that all table and column names are stored in a special "system" DB table.
I'm not sure if this is true for all DB's, but it might me worth investigating.

Good luck.
Kakan

No wonder about it. Your problem statement is not clear.

If you do not connect to the database, how do you plan to get information about the database?

Thanks Rajesh,

i was just trying to use access automation(functionality provided by access to manipulate access without making any connection) to achieve that.However, couldn't find an answer to that.

Thanks,

Hi All,
// Build the SQL statement
SqlString = "SELECT Name FROM MsysObjects where type = 1 AND (Left([Name],4) <> \"Msys\") AND (Left([Name],1) <> \"~\")";
// Execute the query
recset.Open(CRecordset::forwardOnly,SqlString,CRecordset::readOnly);

I have found this piece of info. MsysObjects table contain all the info about tables, queries,reports in access database.

when i try to query MsysObjects table "Access is denied". I don't know where is it located & also it is undocumented. How can i query MsysObjects table?

Please Help!

Problem using Tree

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;  // initializing root<br />
if (file_type == 2)   // if directory detected<br />
{<br />
   tvInsert.hParent = root;	<br />
   tvInsert.hInsertAfter = NULL;<br />
   tvInsert.item.mask = TVIF_TEXT;	//LPCSTR<br />
   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)   //if file is detected<br />
  {<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?

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.

Problem updating the status bar

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)!
