Are you able to read the data? if Yes
Use SetWindowText() to set the data in the text box.

Somethings seem HARD to do, until we know how to do them.

Hi,
Thanx for replying.
I do not understand what you mean. Which namespace holds this method? I do understand that the method takes an id to the form it´s suppose to set text to and the text parameter. But I do not no how to implement it. I would be grateful if you could give me a clearer explanation.

cheers

Thanx for your reply.
Kind of embarrassed right now...

m_edit is the name of the TextBox? What am I missing here?
If the id of the TextBox is idTextBox how do I apply the SetWindowText method on it?

cheers

hey, are you using MFC ? Unsure | :~

it seems that you are using Managed C++ (for the .NET framework).

it seems also that you should teach yourself to the basics of C++ Wink | ;)

I think TextBox is CLI/C++ and m_edit is CEdit m_edit in MFC you can use m_edit.SetWindowText(values);

No problem. Larger crimes have been committed! It just helps to fully qualify your question so that you/we are not off chasing rabbits.

Hi,

How can I add a circle on top of the bitmap image?
I added the following code to draw a rectangle on top of bitmap image. But rectangle is underneath of the BMP image.

CCLientDC pDC(this);
pDC.MoveTo(100,100);
pDC.Rectangle(20,20,30,30);

Please help me.

thanks in advance

is it just for drawing purpose? or do you want to save it to the file?

it is easy to place a rectangle over bitmap. first draw teh bitmap using BitBlt or StretchBlt, then draw the rectangle over it. it will work

Hi Sarath,

Following is the code ... I'm new to VC++/MFC.

m_hBmpNew = (HBITMAP) LoadImage(AfxGetInstanceHandle(),
"bng4.bmp",IMAGE_BITMAP,
0, // desired width
0, // desired height
LR_LOADFROMFILE);

if( m_hBmpNew == NULL ){
AfxMessageBox("Load Image Failed");}

// put the HBITMAP info into the CBitmap (but not the bitmap itself)
else{
m_st1.GetClientRect( &rectStaticClient );
rectStaticClient.NormalizeRect();
m_size.cx=rectStaticClient.Size().cx;
m_size.cy=rectStaticClient.Size().cy;
m_size.cx = rectStaticClient.Width(); // zero based
m_size.cy = rectStaticClient.Height(); // zero based
// Convert to screen coordinates using static as base,
// then to DIALOG (instead of static) client coords
// using dialog as base
m_st1.ClientToScreen( &rectStaticClient );
ScreenToClient( &rectStaticClient);
InvalidateRect(&rectStaticClient);

// Added to draw a rectangle
CCLientDC pDC(this);
pDC.MoveTo(100,100);
pDC.Rectangle(100,100,110,110);

i'm loading bitmap image using LoadImage(). Rectangle image is coming underneath of the bitmap image.

Thanks & regards
Ravi

<pre><br />
void CAnswerDlg::OnPaint() <br />
	{<br />
	CPaintDC pDC(this); // device context for painting<br />
	CRect     Rect;<br />
	GetWindowRect(Rect);<br />
	ScreenToClient(Rect);<br />
m_Image.BitBlt(pDC.m_hDC,Rect.left,Rect.top,Rect.right,Rect.bottom,0,0);<br />
  pDC.MoveTo(100,100);<br />
  pDC.Rectangle(100,100,210,210); <br />
