Hi!!
I am working on an SDI MFC application. I have two dialog boxes. I want to pass some File name from one dialog box to another on clicking OK command button. The file name has to be displayed on the text box of second dialog, when the second dialog appears on the screen .
Can any body tell me , how to declare variables and wat functions to use. I am new to MFC.
Thanx
|

there are two methods
(1)use CWnd::SendMessage( UINT message,
WPARAM wParam = 0,
LPARAM lParam = 0
);
(2)you can add a variable in the CMainFrm. pass the File name of the first Dialog to the variable.then the second
Dialog access it.

You have probably two classes derived from CDialog for your dialogs. Let them be (it's just an example) CYourDlg1 and CYourDlg2.
I guess you are using them like that (supossing they are modal):
CYourDlg1 dlg1;
.
.
dlg1.DoModal()
and
CYourDlg2 dlg2;
.
.
dlg2.DoModal()
respectively.
Now, let's say you want to pass some CString data (containing a fully qualified name of some file), which you get from dlg1, to dlg2.
You must add some data member to each of those two classes: CString m_strFile.
In the OnOK() function of CYourDlg1 you add the line:
m_strFile = ... with the dots replaced by something you are using there ( ).
Before calling dlg2.DoModal(), you initialize the data of dlg2 with data from dlg1:
dlg2.m_strFile = dlg1.m_strFile

Hi All
I am writing one simple application atht will read unicode data from one file. For this i change project setting to _UNICODE. but it gives me error.
So tried solution given in MSDN : THe lines are as given below
Note The Unicode versions of the MFC libraries are not copied to your hard disk unless you select them during a Custom installation. They are not copied during other types of installation. If you attempt to build or run an MFC Unicode application without the MFC Unicode files, you may get errors.
To copy the files to your hard disk, rerun Setup and click Add/Remove Features. Click Language Tools, click Visual C++, and click Visual C++ Class & Template Libraries, and select both ATL MFC Shared Libraries Unicode and ATL MFC Static Libraries Unicode.
but when i run setup(or rerun setup) i doesnot get Add/Remove Features
option anywhere during installation.
CAn ny body help me what to do.
I am installing Micrisoft Visual C++ 6.0
Thanks in advance
Regards
Amit

Code snippet is
// Byte-order mark goes at the begining of the UNICODE file
_TCHAR bom = (_TCHAR)0xFEFF;
CFile* pFile = new CFile();
pFile->Open( strFile, CFile::modeCreate | CFile::modeWrite );
pFile->Write( &bom, sizeof(_TCHAR) );
pFile->Write( LPCTSTR(strText), strText.GetLength()*sizeof(_TCHAR) );
pFile->Close();
Actually i am trying stdiofileEX ex given under heading
Easy text document conversion - ANSI/Unicode and Unicode/ANSI

Search for this file in Ur PC "MFC42UD.dll" n let me know soon
if its not there then,
"http://www.microsoft.com/msdownload/platformsdk/sdkupdate/"
Go to the above link, you will be automatically redirected to the download page or click on the 'Click here' link.
On the redirected page there is a link for
PSDK-x86.exe
Click on the link and install the SDK. It takes some time for install.
I m too busy n cant look into Ur prob neatly.still U can send me Ur proj.
I might see once I m finished up with my work.
BYe

Err... I know you are well intentioned, but this is about Visual C++ installation of MFC libraries; it has nothing to do with the OS...

What do you see in the first screen? Do you see options for 'Typical' and 'Custom' installations?
Try going through the Control Panel - Add or Remove Programs, locating your Visual Studio installation there and invoking the setup from there.

while installing the VS you need to choose to install unicode libs so that you can develop unicode supported application.

but how to select to install unicode libraries?
|
|
|
|
|
I dont exactly remember now, but you need to do custom installation and check for all sub-installation of each option and check unicode libs, by default it is not checked so you dont get the unicode libs.

I have an SDI application with 2 Splitter window pane [(2x1)(rxc)]. The first row is having a view derived from CListView and second is derived from CFormView.
I want to disable the scrollbar in second row containing the Form.
