Have you called GetWindowText in that Function or UpdateData(FALSE) !

Use:

GetDlgItem(IDC_WORD)->GetWindowText(m_WORD);

There is another way to do it Smile | :)

Assign a "Control" variable to your edit box (CEdit m_textEdit).
Use the method GetWindowText() for retrieving the results

void CDemo::OnBnClickedSearchButton()
{
    ...
    CString userResponseText;
    m_textEdit.GetWindowText(userResponseText);

    // userResponseText now contains user response..
    ...
}

Here you don't need to worry about UpdateData that usually has side effects.

Just wanted to give you another way to do it.

.ncb and .pch file

Hi all

I have a project, created in VS2005.

When I enter its directory, inside I have 2 files and 3 folders : Debug, MyProject, Release, MyProject.ncb, MyProject.sln

Strange is that MyProject.ncb is 16 MB in size.
And other files(folders), together are only 4 MB(If I clear the debug and release folders).

Strange is also that MyProject.pch file is 12MB, when Debug folders of my project is not empty.

Why are these files so large ?

Size of total source files I use is only 3MB.

Thank you.

NCB is the Intellisense Database. This sometimes messes up BADLY. I have had a NCB-File with a size of 1.2 GB (!!!). Sometimes the Parser will get a hick-up and go crazy. Just delete the file, it's automatically recreated when you reload your project. Looking stuff up (code completion etc.) might be a bit slow, but will soon get back to its old self.

The PCH-File is the precompiled header file. You can delete that one as well, it also will be recreated. If it is not there, compiling might take a bit longer (because it has to be recreated).

If you do not need recompiled headers, turn them off in the project properties.

Cheers,
Sebastian

Are you talking about the control which looks same as Grid Controls in VB?

if so then there is CListCtrl class which provides such tabular information sroring

Ok,
Then you may use the CListCtrl by setting the style property to report
and after that insert the columns programatically

Release : release mode without unicode support, linked with MFC in DLL.
Release Unicode : release mode with unicode support, linked with MFC in DLL.
Release Static Unicode : release mode with unicode support, with MFC statically linked in the app.

"#pragma hdrstop" directive which terminates the list of header files eligible for precompilation in order to reduce the amount of disk space used by precompiled headers.

Precompiled header files can be shared between the various source files of your project only if the header files listed prior to the #pragma hdrstop are identical.
This is more specific to C++ Builder

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

#pragma hdrstop may be inserted in the primary source file at a point prior to the first token that does not belong to a preprocessing directive. This enables the user to specify where the set of header files that is subject to precompilation ends. For example,

#include "xxx.h"
#include "yyy.h"
#pragma hdrstop
#include "zzz.h"

Here, the precompiled header file includes processing state for xxx.h and yyy.h but not zzz.h . (This is useful if the user decides that the information added by what follows the #pragma hdrstop does not justify the creation of another PCH file.)

Hi all,
I have created a DLL and its header name is simple.h which contains a global variable multiplier n a function multipy. For testing this dll i created a dialog based application n #included simple.h in CheckTestDll.h.
This CheckTestDll.h is #included in CheckTestDllDlg.h in which i m using the structure defined in header file of DLL.
But when i compile this test application i get this error

error LNK2005: "long multiplier" (?multiplier@@3JA) already defined in CheckTestDll.obj

Can anyone help me.
Thanks in anticipation.

Global variables are not recommended to host in header files.

Since the DLL is written by yourself. I suggest you to move that global variable(s) into a .CPP file of that DLL project.
