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)
ON_WM_CREATE()
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?

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.

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.

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?!
|
|
|
|
|
Hi,
Can u please elaborate
Thanks,
Lakshmi.

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.

I am developing a palm conduit in VC++, but I'm kinda stuck.
There are 3 parts to my question:
1. How do I connect to a URL and give it access to a page that requires a username and password?
2. How do I extract JUST certain peices of data from the web page (I know exactly where they are)?
3. How do I send back that data (download it)?

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!

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();

In MFC, if I use _spawnl( _P_WAIT, process 2, str2, str3, str4, NULL ) function to call process 2 in process 1. How can I get the str2, str3... in process 1? Thanks. And can I hide the window of process 2 when the process 2 is running?

Don't use _spawnl(). Use CreateProcess(), which is well-documented in the Win32 API documentation.
