Everyone was a newbie once...
There are MANY (legions) of books available... I wouldn't promote piracy (no, not me!), but several are even available in various places on the net, if you know where to look...
Teach Yourself Visual C++ in 21 Days (ambitious title)
Visual C++ Unleashed
etc...
Both take you step by step through different projects and teach you WHAT you can do so you can learn HOW to do it...
If you are like me, you would want a real-print version of the book so you can thumb through it...
Good luck!

// TODO: Add your control notification handler code here
CString strTitle ;
int nIndex;
UpdateData(); // Transfer data from controls to variables
//get currently selected text
nIndex = GetDlgItemText(IDC_TITLE, strTitle); //assigning selected
m_strFullName = strTitle + " " + m_strFirstName + " " + m_strLastName;

Does this error happen even with a Rebuild All?

See this code
CDC m_dc,m_dc2;
m_dc.CreateCompatibleDC(GetDC());
m_dc2.CreateCompatibleDC(GetDC());
HBITMAP hbit=CreateCompatibleBitmap(GetDC()->m_hDC,800,600);
HBITMAP hbit2=CreateCompatibleBitmap(GetDC()->m_hDC,800,600);
hbit=(HBITMAP)m_dc.SelectObject(hbit);
hbit2=(HBITMAP)m_dc2.SelectObject(hbit2);
hbit=(HBITMAP)LoadImage(NULL, _T("c:\\1234.bmp"), IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE);
hbit=(HBITMAP)m_dc.SelectObject(hbit);
m_dc.TextOut(0,0,_T("And is this your answer"),23);
m_dc2.BitBlt(300,300,200,200,&m_dc,0,0,SRCCOPY);
hbit2=(HBITMAP)m_dc2.SelectObject(hbit);
CImage m_Image;
m_Image.Attach(hbit2);
m_Image.Save(_T("e:\\test.bmp"));
m_Image.Destroy();
m_dc.DeleteDC();
m_dc2.DeleteDC();
DeleteObject(hbit);
DeleteObject(hbit2);

That leaky piece of code helps the OP how?

Besides the fact that it has nothing to do with the question asked?
Like I stated, it leaks. "Only" one GDI object - you get lucky - the system
cleans up most of the problems. Here's an analysis:
CDC m_dc,m_dc2;
m_dc.CreateCompatibleDC(GetDC());
m_dc2.CreateCompatibleDC(GetDC());
HBITMAP hbit=CreateCompatibleBitmap(GetDC()->m_hDC,800,600);
HBITMAP hbit2=CreateCompatibleBitmap(GetDC()->m_hDC,800,600);
hbit=(HBITMAP)m_dc.SelectObject(hbit);
<font color="Red">
hbit2=(HBITMAP)m_dc2.SelectObject(hbit2);
<font color="Red">
hbit=(HBITMAP)LoadImage(NULL, _T("e:\\8bit.bmp"), IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE);
<font color="Red">
hbit=(HBITMAP)m_dc.SelectObject(hbit);
<font color="Red">
m_dc.TextOut(0,0,_T("And is this your answer"),23);
m_dc2.BitBlt(300,300,200,200,&m_dc,0,0,SRCCOPY);
hbit2=(HBITMAP)m_dc2.SelectObject(hbit);
<font color="Red">
CImage m_Image;
m_Image.Attach(hbit2);
m_Image.Save(_T("e:\\8bit_test.bmp"));
m_Image.Destroy();
<font color="Red">
m_dc.DeleteDC();
m_dc2.DeleteDC();
DeleteObject(hbit);
<font color="Red">
DeleteObject(hbit2);
<font color="Red">
<font color="Red">

Hi..
Previously I was using Modal dialog box with Thread, to continue one process and showing the dialog box continuously. But as I am getting problem with thread I need to use Modeless dialog Box. But when I replace the code of Modal Dialog box with Modeless Dialog Box. It hangs when redrawn.
i.e. When it redrawns nothing displays in the dialog box.
The Code I am using is as follows
My application is such, that continuously check the data from the server and displys on the dialog.
hDisOwnDlg=CreateDialog( g_hInst, MAKEINTRESOURCE( IDD_DISOWN ), NULL, DisOwnDlgProc );
ShowWindow(hDisOwnDlg,SW_SHOW);
Please Help me.

Did you use of any function or event like WM_SIZE on your project? does your previous problem solve?
|
|
|
|
|
No i am not using WM_SIZE. and my previos problem hasn't been solved.

What thread are you creating the dialog on?
What thread do you do the continuous checking on?

I have function that retrives the data from Internet Server throught Socket after some interval and show it on the dialog box. Previously I was using Modal Dialog box, calling this function through thread before creating dialog and termination thread when Dialog Ends.
But I think if I will use the Modeless Dialog box the above thing will be much easy. And So replaced the code of modal dialog box with Modeless Dialog box. But as I told earlier it gets blank when it redrawns.

Well if you're doing processing on the same thread the modeless dialog
was created on, then that can cause the dialog not to get its
WM_PAINT messages (and any others).

Hi,
I have created a Local User Account programmatically say "MyUser" and then Iam Creating a process as MyUser. From within this process( which means Iam working as "MyUser") I have created a Pdf file and then Iam trying to open it Programmatically using DOS command "cmd /c start myfile.pdf". But the Pdf file is not getting opened. Even when I click on it. It Says "Access denied". The Same file if I login using "MyUser" it is being opened.Then after If Iam trying to Open it Programmatically or Normally I could open the File from my current user Account.
So,Is it a must for me to login as "MyUser" atleast once to work with that user Programmatically?
What I observed is once I login as that user, In Documents and Settings a folder is created under the name "MyUser".
So Is there any thing more I need to do apart from creating a user Programmatically?
Any suggestions would be helpful.
Thanks in Advance.
Today is a gift, that's why it is called the present.

Firstly, do you know the freshly created pdf exists?
If so, it probably was created so that only MyUser can open it.
Forgetting acrobat etc - can you copy the file using explorer? If not, then you may need to modify the CreateFile code that MyUser runs to use a security context (one of the params that's usually NULL) to create the file with "everyone can read this" privileges.
*Then* worry about whether the file is decent.
You may even want to start testing by creating a text file with "hello" in it, so you can use simpler software to check things out.
Iain.

Why not just use ShellExecute(hWnd, "open", "myfile.pdf", ...)?

My application works as below.
Client sends its MAC address and Wait time(in seconds) to server and goes to sleep state.
Server receives them and sleeps for received no. of seconds. After that time period, server sends Magic Packet to client to wake it up.
Now the problem is, if Client sends Wait Time less than 120 seconds, server wakes up the client successfully. But if that time period is 120 or greater than 120, client does not wake up even if server sends magic packet successfully. What could be probable cause for the same.

Hello,
I have a CDatabase object.But the following ExecuteQuery doesn't work.It gives an error "Syntax error in field definition"
CDatabase CurrentDatabase;
CurrentDatabase.ExecuteSQL("Create Table Purchase (Amt decimal(10,2))");
but
the following works
CurrentDatabase.ExecuteSQL("Create Table Purchase (Amt int)");
I have checked with SQL both the statements have right syntax.
What must be the problem?

Can you execute this statement from within SQL itself? Have you tried:
CurrentDatabase.ExecuteSQL("Create Table Purchase (Amt decimal(10))");or
CurrentDatabase.ExecuteSQL("Create Table Purchase (Amt decimal)");
