You need to include <string> to use the string class.

Use the IXMLDocument interface.

Hi,

I want to draw a rectangle in a Rich Edit Text control (CRichEditCtrl) which is embedded on a Tab Control.

I am using CFormView (form as my container to place all my controls TabCtrl, RichEditCtrl, etc.) I need to get the correct Device Context to do the drawing in my CFormView::OnDraw(CDC* pDC) method.

Can someone help me out?

Thanks in advance,

Ahmed Kabir

Perhaps you want to subclass your CRichEditCtrl and override OnPaint()

Hi !

My C++ app needs to read an external text file and display it on screen. But, this text file can contain specific commands to change what has to be displayed by my app.

For instance, the text file could be :

Hello
[if foo]
Foo
[else]
Bar
[endif]

and my app should display (depending of foo) : Hello Foo.

The problem is that I don't know where to start. Should I just parse the text file and just check each [] ? Should I write a real interpreter (I have no idea how to do this). Can I reuse something existing ?

Any help, suggestions or idea are welcome !

THanks !
Jerome

How to add a Bitmap image for background of titlebar

26-Jul-05 3:01

Depends how hardcore you want to get. If it's simple you could get away with just parsing and using a simple hash table for your variables. Either way you'll want to take a look at these

Hi,

I'm working on an SDI application using MFC.
I'd like to change the background of titlebar and toolbar by adding a small bitmap image which looks like a short vertical line.

I found some source codes to change background color of titlebar.
But I don't know how to change the background of titlebar by a bitmap image.

Please let me know how to add the bitmap image as a background.

problem displaying bitmap

26-Jul-05 2:48

Look into WM_NCPAINT, LoadImage and BitBlt.

Hi
I am doing a project on image processing with VC++. When I try to display the bitmap(8 bit) on the screen using SetDIBitsToDevice() the actual color is not mapped correctly. The same code works fine with 24 bits bitmap.

Pls help

Thanks in advance

Hi guys,
I am writing a simple Windows Spy untility (like in VStudio tools),
I am having problems when dragging the cursor over different windows.I manage to draw a rectangle over them but when i move mouse to another window the retangle still stays on the previous window. I tried to store the previous windows handle and when mouse was over another window i simply called the Invalidate() function to the previous window.
For some strange reasons this worked only for 90% of the windows , but in some cases the retangle still remained over some windows.
Can anyone suggest any other way of achieving this??

Regards

To get message from Windows if user writes on hard disk

26-Jul-05 2:56

Try calling UpdateWindow() after Invalidate(). If this doesn't work you can try hiding and then showing the window.

My program has to get the message from Windows, if the every user wants to save his information on hard disk, or if the every user wants to connect to my computer by local net. How I can make this function?

I would have a look / search for FindFirstChangeNotification. This lets you monitor any
changes to files in a directory. If that is not enough, look at FileMon on www.systinternals.com[^] and
be impressed at the amount of work that took... As I understand it, they had to write a filesystem
driver to sit below the user processes. Gnarly.

Construct 2 CTime objects (cTime1, cTime2):

CTime::CTime( int nYear, int nMonth, int nDay, int nHour, int nMin, int nSec, int nDST = -1 );

then you'd compare them (cTime1 > cTime2).

wat do u mean by construct 2 ctime object?

do u mean like
int ctime1;
int ctime2

CTime::CTime( int nYear, int nMonth, int nDay, int nHour, int nMin, int nSec, int nDST = -1 );

like this?

In this example it's compared the current time with a fixed date .

<br />
CTime ct1, ct2;<br />
ct1 = CTime::GetCurrentTime();<br />
<br />
ct2 = CTime(2005, 07, 30, 23, 01, 00); //CTime::CTime( int nYear, int nMonth, int nDay, int nHour, int nMin, int nSec, int nDST = -1 );<br />
<br />
// Now you can compare them.<br />
if(ct1 > ct2)<br />
{<br />
  // current time is greater than the fix one<br />
}<br />
else<br />
{<br />
  // fixed time is greater or equal than current time <br />
}<br />

I hope that it's what you wanted,
Marc Soleda.

In addition to Marc's suggestion, if you'll simply put the dates in YYYYMMDD format, then you can easily compare them.

//     YYYYMMDD   YYYYMMDD
ASSERT(20050726 > 19680906);
