Just use printf:

char szText[255];<br />
printf(szText,"Red value: %i, Blue value: %i, Green value: %i",GetRValue(...),GetBValue(...),GetGValue(...));

Of course, you have to replace the ... by your COLORREF variable Wink | ;)

For the first one, just use COLORREF GetColour(); from the control.

Dude, when you use classes from an article here, first read how to use it (and there is also example source code with the article). If we don't use this control, we don't know how to use. It just took me 30 seconds looking at the text of the article to find how to use it.

I have service application which has to launch an application in the context of the current interactive user. If there is not interactive user, then the application will not be started.

I tried using CreateProcessAsUser, but then I need to have a token to that user's session. How do I get that?

Thanks!

I need to run my app on the same session as the current interactive session. LogonUser will create a different session. Furthermore, how do I get to know the username, etc.....

I want to achieve something of the sort that DCOM does. For DCOM servers, we have the option to specify to launch it in the interactive user's session. Similar kind of thing is what I am looking for...

Yep, sure. Depends on which IDE you use. For 2005, you go in the project properties -> c/c++ -> general -> additional include directories. It is almost the same for VC6 (except that is not displayed the same way).

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.

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.

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?

Problem using Tree

Aqueel30-Nov-05 23:36

30-Nov-05 23:36

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.

files of innerdir
..

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?

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

Pasting the Windows Clipboard into MSHTML = RTF to HTML Conversion

Neville Franks30-Nov-05 22:40

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.

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