"A" and "T" are strings not characters.
'A' and 'T' represent character values.
if(text.GetAt(0) == 'A)) <- no error
text.SetAt(0,'T') <- no error.

This program reads .bmp files and like types them in a game screen. I would like it so to be activated by dragging a crosshair over the game screen so the program knows where the screen is
The game I am talking about is runescape.
This program would read the .bmp and type the word in and then press the key enter
If you would like to see a program like this I will show you

Hi,
Can anyone please help me with this problem?
I have a dialog with a CRichEditCtrl and a button.
The user highlights a piece of text and clicks the button.
When the button is clicked, a modal Dialog is created.
This modal dialog has a CEdit and a button. The CEdit contains a variable of type CString.
The user enters text in this CEdit.
When the OK button is clicked, the text in the CEdit should replace the highlighted text in the CRichEditCtrl in the initial dialog.
When the program is executed it gives a "Debug Assertion Failed" error.
The assertion is as follows (from AFXCMN.H):
<br />
AFXCMN_INLINE void CRichEditCtrl::ReplaceSel(LPCTSTR lpszNewText, BOOL bCanUndo)<br />
{ASSERT(::IsWindow(m_hWnd)); ::SendMessage(m_hWnd, EM_REPLACESEL, (WPARAM) bCanUndo, (LPARAM)lpszNewText); }<br />
My code is as follows:
<br />
void MyModalDialog::OnBtnOk() <br />
{<br />
CString returnStr = m_edit;
MyProjectDlg dlg;
dlg.m_fileContents.ReplaceSel(returnStr, FALSE);
}<br />
Thanks very much,

Do not try to replace the text from within the dialog. Replace the text after the dialog closes, it is easier.
MyProjectDlg dlg; // dialog type now exist
// but the window does not exist yet
// therefor, you can not send it any messages.
According to your comments: The MyProjectDlg should already exist and it should be lunching the MyModalDialog, but here you are asking MyModalDialog to create a new MyProjectDlg and replace the selected text in that (which also does not exist).
void MyProjectDlg::SomeFunction()
{
MyModalDialog dlg;
dlg.MySetText(...);
if( dlg.DoModal() == IDOK )
m_fileContents.ReplaceSel(dlg.MyGetText(), FALSE);
}

Thanks in advance..

programatically or by using the windows explorer search/find ?
programatically, use CFileFind ( or FindNextFile and FindFirstFile )

Get a copy of "Agent Ransack", it can find anything. There know there was an article here some where, but I can not find it.
You could write your own using the MS-C functions _findfirst() and _findnext() or the SDKs FindFirstFile() and FindNextFile(). The hard part is switching directories, for further searching. All the "File I/O Functions" functions are listed in the MSDN, you'll have to do a search for that exact string (not listed in index - as usual).
P.S. There is an article on "Agent Ransack" at CP.
Good Luck!

I have made simple program for HTTP download in the Visual Studio .NET (VC++
7.0). I have overriden MFC class CAsyncMonikerFile. I have overriden method
OnStopBinding(HRESULT hresult, LPCTSTR szError) in my derived class , but
this method wasn't called at the end of the bind operation (when all data
came). But overriden method OnStartBinding()was properly called. Can you help
me with this problem? Is there any serious bug in the MFC class
CAsyncMonikerFile in VC++ 7.0?

I do not know why you overrode the OnStopBinding() function/method, but is sounds like you need to call the base version in your overriden version.
OnStopBinding(...)
{
BaseClass::OnStopBinding(...);
}

Hi John,
I have to call some functions, when all data are downloaded and the OnStopBinding is right place for it. But the problem is that OnStopBinding is not called in VC++ 7.0, but in older VC++ 6.0, everything was all right (OnStopBinding is called after OnDataAvailable()).

Hi
I want to change the default cursor in my app. I tried following code.
bool m_bcursor;
BOOL CTestDlg::OnInitDialog()
{
CDialog::OnInitDialog();
// TODO: Add extra initialization here
lhCursor = AfxGetApp()->LoadCursor(IDC_CURSOR);
SetCursor(lhCursor);
m_bcursor = true; //set to true
return TRUE; // return TRUE unless you set the focus to a control
}
BOOL CTestDlg::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message)
{
// TODO: Add your message handler code here and/or call default
if(m_bcursor)
return true;
else
return CDialog::OnSetCursor(pWnd, nHitTest, message);
}
But whenever I open About Dialog, cursor it changed to default cursor.
What should I do to change cursor the moment my main dialog gets focus?
|

|

You need to set the cursor each time the OnSetCursor message is triggered. Dump the boolean member variable, and make the handle to the cursor a member variable of the dialog box:
HCURSOR m_hCursor;
Initialize it in the constructor:
CMyDialog::CMyDialog() : m_hCursor(NULL)
{
m_hCursor = AfxGetApp()->LoadCursor(IDC_MYCURSOR);
}
and in OnSetCursor()...
if (m_hCursor != NULL)
{
SetCursor(m_hCursor);
return TRUE;
}
// default stuff here
 Pssst. You see that little light on your monitor? That's actually a government installed spy camera. Smile and wave to big brother!

Good advice! But you do not need to maintain a copy of the cursor handle.
From MSDN:
"The LoadCursor function loads the cursor resource only if it has not been loaded; otherwise, it retrieves the handle to the existing resource."
In other words, the system maintains a copy of the cursor handle for you.
SetCursor(AfxGetApp()->LoadCursor(IDC_MYCURSOR));
The cursor is a resource included in the .exe (or sytem resoruces). Therefore, you do not need to test the handle. If the handle returned is not valid then there is a much bigger problem involved (and the program has locked up or crashed, do to lack of memory).
