Re: Linking Input to an email output - C / C++ / MFC Discussion Boards

(1) Add a CSplitterWnd to your CMainFrame class say m_split.

(2) Derive two view classes [say you have CMyTree and CMyList which are classes derived from CTreeView and CListView]

(3) m_split.CreateStatic(this,1,2);

(4) m_split.CreateView(0,0,RUNTIME_CLASS(CMyTree),CSize (150,100), NULL);
m_split.CreateView(0,0,RUNTIME_CLASS(CMyList),CSize (150,100), NULL);

Hope this helps

Thanks for replying,

This is what I had done for the original split window....

if(!m_ospltWindow.CreateStatic(this,1,2))
return false;
if(!m_ospltWindow.CreateView(0,1,RUNTIME_CLASS(CGraphView),CSize(200,200),pContext) )
return false;
if(!m_ospltWindow.CreateView(0,0,RUNTIME_CLASS(CChildView),CSize(200,200),pContext) )
return false;

I tried doing what you said for splitting one of the above splits but it didnt work. I have a menu option that when selected I want one ov the above splits to split again...know what I mean...

So in my OnSplitAgain function I had....

m_ospltWindow1.CreateStatic(m_ospltWindow,1,2);
m_ospltWindow1.CreateView(0,1,RUNTIME_CLASS(CGraphView),CSize(200,200),NULL);

m_ospltWindow1.CreateView(0,0,RUNTIME_CLASS(CChildView),CSize(200,200),NULL);

but it didnt work.... Dead | X|

Hi,
I have a slight problem copying a class whose pointer I have. I have an abstract base class, and several derived classes, and a pointer pointing to one of the derived classes, but the pointer is of BaseClass* type. I want to copy the derived. Can I do it using the copy constructor?

Here's a little code

class CBaseClass
{
protected:
    CBaseClass();
    CBaseClass(CBaseClass &src) {.... foo ....};
}

class CDerivedClass : public CBaseClass
{
public:
    CDerivedClass();
    CDerivedClass(CDerivedClass &src) {.... foo ....};
}

In the example how could I do this
CBaseClass *destination;
CBaseClass *source = new CDerivedClass();

.... how can I copy the "source" to "destination", and I don't mean a binary copy - there must be a proper C++ way of doing it.

With time we live, with money we spend!

Hmmm, what you're asking for is the equivalent of a virtual copy constructor, which C++ doesn't have. I'm not sure how common your scenario is, but I personally haven't run into it, as far as I can remember...

Anyway, you have one of two options:

1. Create a virtual "Clone" function in your base class and override it in your derived classes.

2. Find the type of the object to which the pointer points and create a new object of that type using the copy constructor. For example, you the code you give, you know that source points to a CDerivedClass object. You can then do this:

CBaseClass* destination = new CDerivedClass(*(CDerivedClass*)source);

I'd go with option 1; it's cleaner and safer.

Regards,
Alvaro

Is destination initialized to anything or do you just want to point destination at the same data source is pointing at? If the later then it's just

<br />
destination = source;<br />

or did you mean

<br />
CDerivedClass *destination;<br />
CBaseClass *source = new CDerivedClass();<br />

in which case it's

<br />
destination = dynamic_cast<CDerivedClass*>(source);<br />

could you provide more info on what you want to do? How are destination and source being used?

Hi,

I have an ActiveX control on top of a CFormView and I'm trying to use tooltips in my application. It appears that when the OnToolTipNeedText() method is called, it get's called once for the ActiveX control and once for the CFormView. I'm pretty sure of this because I get two tooltips in my application, one below the mouse and the other at the bottom of the window.

Does anyone know how I can tell if the message is coming from the ActiveX control or the CFormView? I tried looking at the pNMHDR->hwndFrom and compared it to myCtrl->m_hWnd but it is never equal, in fact, it never equals the CFormView->m_hWnd either. I basically just need to concern myself with the message from the ActiveX control and ignore all other messages.

Thanks for any help you can provide,

Craig

I am building a rather simple dialog program that receives input, however, I am having trouble linking this generated output to be transmitted in email form through outlook explorer. I am still pretty much a beginner programer in C++, so any help would be appreciated.

Thanks

I'm getting very frustrated with trying to send email from my computer programmatically. From what I've been able to find out, there are two choices:

- use MAPI:
problem: It pops up dialog boxes requiring user input when it is unable to send messages or when various errors happen. Therefore it is not useful to me since I want to run the program on a computer that isn't being looked at by a human.

- use SMTP:
problem: You need a computer that you can connect to on port 25 and say HELO\r\nMail From: a@b.c\r\nRCPT To: x@y.z\r\ndata\r\nfirstline\r\nlastline\r\n.\r\nQUIT\r\n or whatever. In any case I don't have a computer that I can send this through so I can't do this either.

But check out the code below for an example of doing MAPI. You have to put a line of code each of mapi init and uninit and include mapi.h. The functions i call at the end here just display the appropriate error message according to a switch statement using strings taken from the msdn docs. hope it helps.

If you want to use Outlook Express or whatever it is, that is your default email client, try this.

Use ShellExecute and open "mailto:aaa@aaa.com"

replace aaa@aaa.com with your target email address

I hope I got your question correct.

How can I show the progress of an upload or download I have in progress in my program?
My program connects to my ftp and nagivates to a folder and uploads a specific file type, sdm.

I have a progress control in the same window which has time to complete underneath. How do I go about making it work for when an upload is being done or a download?!?

Hope that wasnt too broad!
Thanks
Ashman

Start off a thread which can update the progress bar till your upload/download finishes

Nish

or put your upload/download stuff in a thread. And update the progress bar in your main thread

Is there a way to align text in a status bar pane? I need to right align one of the panes in my status bar.

Also, I need to know how to include a tool-tips type display when the pane is scrolled over. Any help is appreciated.

Hi all,

I have two custom open file dialog. One is very large, and the other is approximatively the same size as the default open dialog.

My problem is under win2000, the open dialog remember it's last size. You see the problem, if i open the bigger one first, and after closing, i open the small one, suprise, it's not small, it's now the same size as the last one.

I can not find a trick to not let Win2000 remember the last size.

Can someone have some clues?

Is there a way to highlight the entire first column of a listview and not just highlight the contents of the cell?? LVS_EX_FULLROWSELECT highlights the entire row, which I don't want. But not using that means that only the contents of the first column are highlighted.

Is there a way to adjust the margin in either;
a subitem of a listview
or a combobox

like you can set the margin in CEdit?
What i'd really like to be able to do...is move, ever so slightly, the edit portion of the combobox. I paint a combobox in a subitem of a listview. When the row gets focus, I grab the text from the subitem and put it in the combobox. The text shifts to the right a couple pixels. Plus the combobox border takes up a lot of space and i'd like to shift the text shown up 2 pixels. Any ideas?

Anyone have an example of column resizing when the user drags the gridline. I don't have a listview header but still want the user to be able to resize the column width.

thanks
mike

Can a VB Active X dll be call from a win32 console application? I have managed to call it from a MFC but I would like to called it from a win32 console application. If the answer to the question is yes HOW????

thanks

How are you calling it from MFC? As far as I'm aware COM objects can be called from console applications. A simple call to CoCreateInstance with the IID and CLSID of your COM server should be prove either way if it works. Don't forget to call CoInitialize first though.

Create a new class from Importing library. This option will create a new class with the method in the dll

Any idea how to stop the MDI Child Windows from being able to be resized? I don`t want the cursor to change either when the user goes over the border with the mouse. I have tried using WM_SIZE with no joy. I`m sure theres quite a simple solution, can anybody come up with the goods?

Cheers,
Alan. Confused | :confused:

AEGC

Prevent resizing: handle WM_GETMINMAXINFO.
Prevent cursor changing over border: handle WM_NCHITTEST.
See MSDN for specifics.

WM_SIZE is send when the sizing operation is finished. That's why it doesn't work for you.

Cheers
Steen.

I found a couple more windows messages that might come in handy:
WM_ENTERSIZEMOVE
WM_EXITSIZEMOVE
WM_SIZING
WM_MOVING

Hi
I'm already getting mad, I hope someone can help me Big Grin | :-D

I want to send a sting beween two applications.
What I have so far is:

const UINT WM_MYAPP = RegisterWindowMessage("unique id");
.
.
.
char server[] = "something";
char ip[] = "111.222.333.444";

PostMessage(HWND_BROADCAST, WM_MYAPP, (WPARAM)server, (LPARAM)ip);

But in newsgroups I read that I is not possible to exchange strings using this method.
Here http://www.codeproject.com/threads/ipc_tute.asp is a good example that works but it uses memory mapped files and is a bit too complex for my purpose.

Is there no easier way to exchange strings between two applications?

regards Smile | :)

Use the WM_COPYDATA message. I believe there are a few articles here on CodeProject about doing just such a thing.
