You have to create the edit control in your view's OnCreate() handler.

int CTestView::OnCreate(LPCREATESTRUCT lpCreateStruct) 
{
	if (CView::OnCreate(lpCreateStruct) == -1)
		return -1;
	
	// TODO: Add your specialized creation code here
	m_myEdit.Create(WS_VISIBLE|WS_CHILD|WS_BORDER, CRect(10,20,30,40), this, ID_MYEDIT);
	return 0;
}

Thanks. I've successfully added it. I also added a combobox on the window, which dynamically contain some string. What I want is that when make a choice in the combobox, the code will do different things, how can I do that? It's simple in Dialog based program, but I have no idea how to do that in non-Dialog-based.

You do it exactly the same way as in a dialog. You just have to do it manually, classwizard will not help you. Add your message map entries and member functions.

BEGIN_MESSAGE_MAP(CTestView, CView)
	//{{AFX_MSG_MAP(CTestView)
	ON_WM_CREATE()
	//}}AFX_MSG_MAP
        ON_CONTROL(CBN_SELCHANGE, ID_MYCOMBO, OnSelChanged)
END_MESSAGE_MAP()

void CTestView::OnSelChanged()
{
        DoSomethingWhenSelectionChanges();
}

I tried but it does not work. I also tried to change ON_CONTROL to ON_NOTIFY, it does not work either. The function, say CTestView::OnSelChanged() should be declared with type "afx_msg", right? Is there any other trick besides what you said above? By the way, my application is a windows CE program, could this be the reason?

There is a WIN32 function GetFileVersionInfo to get file version information. Is there a "SetFileVersionInfo" or similiar WIN32 function to change the version information?

Re: Chang Dll Version

Up to my knowledge, this information is stored in the DLL as a resource! So you can change it at design time from within your compiler! What do you mean changing the value at runtime? In memory only or do you want the chage to be permenant?!

I know UpdateResource can be used to make the change. Do you know if there is an example showing how to change version information permanently using this function? In MSDN, there are some links about how to change dialog resource and string table resource using the function. But I didn't find anything about version.

Thanks.

Commenting code

26-Jun-01 9:09

Does anyone know how to comment out a LARGE chunk of code in a C++ file.

I know the /* comment here */ but if you want to comment out large portion
of a file and have /* comments */ within the file you have to make /* */ all over the place to do the large part. i.e. I would like to comment out the entire file (or close to it). Some thing like a symbol at the beginning of the
file and one at the end of the file, but nothing in the middle that will stop the comment short. Thanks a bunch in return.

NLS implementation

Hi,

I'm working on making an application NLS compliant which is mainly dialog based. What I've to do is I need to load the application's dialog from a resource dll based on the operating system's language. My implementation is as below.

GetUserDefaultUILanguage = (GETUSERDEFAULTUILANGUAGE*)GetProcAddress(hClusAPI, "GetUserDefaultUILanguage");
LANGID Language = GetUserDefaultUILanguage();

_stprintf(g_tcsTemp, _TEXT("res%x.dll"),Language);
if(strcmp(g_tcsTemp, "res409.dll"))
{
HMODULE hLibrary = LoadLibraryEx(g_tcsTemp, NULL,LOAD_LIBRARY_AS_DATAFILE);

if(hLibrary!=NULL)
AfxMessageBox("Other library has been successfully loaded in the system");
HRSRC ResInfo = FindResource(hLibrary,"#102",RT_DIALOG);
ResHndl = LoadResource(hLibrary,ResInfo);
}
else
{
HMODULE hLibrary = LoadLibraryEx(g_tcsTemp, NULL, LOAD_LIBRARY_AS_DATAFILE);
res = GetLastError();

HRSRC ResInfo = FindResource(hLibrary, "#102",RT_DIALOG);
ResHndl = LoadResource(hLibrary, ResInfo);
}

dlg1.CreateIndirect(ResHndl,NULL);
dlg1.ShowWindow(SW_SHOWNORMAL);

This method seems to work, but since CreateIndirect returns immediately the dialog is seen for a fraction of second. Then I used InitModalIndirect API instead of CreateIndirect making the dialog resource modal. Dialog comes up but it always gives assersion in ASSERT(m_lpszTemplateName == NULL);(DLGCORE.CPP line no.430).

nResponse = dlg1.InitModalIndirect(ResHndl,NULL);
dlg1.DoModal();
If any one knows about NLS implementation by loading dialog from resource dll, Please let me know.

Thanks in advance,
Lakshmi.

Why don't you use a message loop after createIndirect?!

Can u please elaborate

Thanks,

Re: NLS implementation

After CreateIndirect use something like:

MSG msg;

while (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE)
{
if (!IsDialogMessage(&msg))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}

If dlg1 is a local variable then this is might be your problem. The CDialog dtor makes a call to DestroyWindow, so once the end of the function's scope is reached, the dialog will be automatically destroyed.

Try makeing the dialog a data member.

Can't access varables in theApp!

26-Jun-01 4:06

Hello, I'm trying to access a variable in theApp from int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct) using theApp.m_variable to access it.
.. when I type the "dot" in theApp.m_variable I get the list of all the variables in theApp but when I compile the whole lot, I get the error: "left of '.m_variable' must have class/struct/union type"!

One being bugged!

Re: Can't access varables in theApp!

26-Jun-01 5:01

Place the following line at the top of MainFrm.cpp or in a header file if you use it a lot.

extern CMyProgramApp theApp; // This object is defined in CMyProgram.cpp

You could also use

CMyProgramApp* MyApp = (CMyProgramApp*)AfxGetApp();
