The dialog is in a separate class on it's own. Te view class creates an instance of it and calls the doModal() function to display it.

This will assume it is a modal dialog.
You mention needing to update the document, so
you need to add a command handler to the doc.
Either using ClassWizard, or manually, add
a command handler to the document.
BEGIN_MESSAGE_MAP(CMyDocument, CDocument)
...
ON_COMMAND(IDC_MYCOMMAND, OnMyCommand)
...
END_MESSAGE_MAP()
...
void CMyDocument::OnMyCommand)
{
}
You've already got a dialog box. I'll pretend
it has a few member variable that you store
data in.
void CMyDocument::OnMyCommand)
{
CMyDialog dlg (AfxGetMainWnd ()); // Make the dialog a child of the application window - doc don't have one.
dlg.m_bFlagOfSomeKind = FLAG_FOO | FLAG_BAR;
dlg.m_nVariable = m_nVariable; // Copy over a variable from the doc.
if (dlg.DoModal () != IDOK) // Do the dialog.
return;
// Use the results.
m_nVariable = dlg.m_nVariable.
m_nOtherVar = dlg.m_nResultData;
UpdateAllView (); // Sync view(s) with new contents of document.
}
Done!
Iain.

Yes, the dialog is a modal dialog.
Here are some follow up questions:
- What does AfxGetMainWnd() do?
- Can I create an instance of the dialog in the view and display it from there based on some menu choice by the user?
Thanks for the help!

AfxGetMainWnd
If you look it up in the help, it will tell
you that it returns the main CWnd * of the program.
Look in you CMyApp::InitInstance function for
the place it is set.
You *could* run this the function from the
view class (CMyView::OnMyCommand),
and replaced (AfxGetMainWnd ()) with (this).
You would need to look at the CView::GetDocument () function also.

Hi,
I am using this to get the time a file was written to and it looks like it always gives me the GMT time and not my local time.
So...
If I write this
<br />
SYSTEMTIME *sys_time=new SYSTEMTIME;<br />
FileTimeToSystemTime (&fd.ftLastWriteTime,sys_time);<br />
Now, sys_time->wHour will not be the eastern time but GMT,so it will be 5 hours forward.
I can easily take off 5 hours, but if it gives me 0 then I have to rull bakc a whole day or year and I don't know of an easy way to do so...
any idea ?
|
|
|
|
|
See SystemTimeToTzSpecificLocalTime. Or, call FileTimeToLocalFileTime before calling FileTimeToSystemTime.
onwards and upwards...
|
|
|
|
|
Cool !
Exactly what I needed.

i just need a conversion like if i give 1200.25
the class must give a CString like
One Thousand Two hundred and twenty five..
i need this urgently, but i didnt want to re - invent the wheel. , so if you know this please help me..!!
Ninety-eight percent of the thrill comes from knowing that the thing you designed works, and works almost the way you expected it would. If that happens, part of you is in that machine.

how do i represent 1225.25 ?
Engineering is the effort !

I'm a bit confused. Wouldn't "One Thousand Two hundred and twenty five" be represented as 1225, or should the text read "One Thousand Two hundred dollars and twenty five cents" (assuming American currency here)?

I have been trying to get a simple Client/Server application running using the TAO Corba, but having building and then running problems.
Are they any simple
(Get you Started) examples for Visual Studio .Net out there.
I have found some examples on the web, but either cant get them built or dont run.
Thanks.

Hi!
I have this problem with vc++ 6, under windows XP:
Wher running my application (is a Dll!!) on Debug mode running ,in release mode don't work. The same application under windows 2000 don't have problem!!!
You know this problem?????
Tank's all!!
Hi! I'm very happy to talk with everybody about VC++.

The devil is in the details.
Your "application" is a DLL.
But you cannot simply run a DLL.
How is it run? Is it a com server, a DLL for
an EXE you've written?
How is it not running? Is it never being used?
That may be a security thing.
Does it start to run, then dies horrible?
Pepper your code with OutputDebugString (...) and look at DebugMon(?) on sysinternals[^].
etc.
|
|
|
|

Of course!
I have a EXE application that call a DLL!
Are two different applications.
The DLL application code when goes in execution i receive a message that "The memory cannot read".
Now, the same code under windows 2000 works without problem!
Tank's you!

I would put a lot of OutputDebbugStrings in your code, and run Dbgview from www.sysinternals.com[^].
That may help track down the problem.
It is likely to be bad initialisation.
In Debug mode, uninitialised memory gets filled with 0xCD [*], but its filled with NULL in release mode.
So they do behave subtly differently.

[*] I'm not 100% sure of the value, but its close.

Hi Ian!
Tank's you for your disponibility. I have found a solution, but not the problem! I have try to create a new exe and i'have call a part of code.
Now running! I belive that part of the source code are written with "the feet" (sorry for my expression but in my country we say!!). Now i must found the different code from the first application and the new application.
I hope to talk with you again.
Patrizio.

No, in release mode uninitialised memory is undetermined. It can be anything that was at that memory location previously. For this reason you should always initialise memory within your applications.

Turning brain on, you're right.
If its any consolation, I don't trust uninitialised data anyway, so I haven't been caught
but my own misinformation. Hopefully other people ignore me too!

Hey, im trying to write some C++ code that will monitor when a certain usb device is plugged in/ plugged out. I've been on the MSDN website and good idea of what i need to do. However, I'm having trouble with RegisterDeviceNotification. The RegisterDeviceNotification is always returning NULL. I would very much appreciate if someone could point out where ive gone wrong with this code:
Code:
#include <windows.h>
#include <stdio.h>
#include <stdlib.h>
#include <dbt.h>
#include <setupapi.h>
int main()
{
bool result;
HWND hWnd;
char szMsg[80];
GUID InterFaceClassGuid;
void **hDevNotify=NULL;
//CLASSGUID FOR USB DEVICE
InterFaceClassGuid.Data1 = 0x8D948EE9;
InterFaceClassGuid.Data2 = 0xD0AA;
InterFaceClassGuid.Data3 = 0x4A12;
InterFaceClassGuid.Data4[0] = 0x9D;
InterFaceClassGuid.Data4[1] = 0x9A;
InterFaceClassGuid.Data4[2] = 0x9C;
InterFaceClassGuid.Data4[3] = 0xC5;
InterFaceClassGuid.Data4[4] = 0xDE;
InterFaceClassGuid.Data4[5] = 0x36;
InterFaceClassGuid.Data4[6] = 0x19;
InterFaceClassGuid.Data4[7] = 0x9B;
DEV_BROADCAST_DEVICEINTERFACE NotificationFilter;
ZeroMemory( &NotificationFilter, sizeof(NotificationFilter) );
NotificationFilter.dbcc_devicetype= DBT_DEVTYP_DEVICEINTERFACE;
NotificationFilter.dbcc_classguid = InterFaceClassGuid;
hDevNotify=(void**)RegisterDeviceNotification(hWnd,&NotificationFilter, DEVICE_NOTIFY_WINDOW_HANDLE);
if (!hDevNotify)
{
printf("RegisterDeviceNotification failure: %d\n", GetLastError() );
MessageBox(hWnd, szMsg, "ResisterDeviceNotification", MB_OK);
result= false;
}
result= true;
return 0;
}
Thanks

Hi
The first parameter to RegisterDeviceNotification wants a valid window handle to where a WM_DEVICECHANGE message will be sent - if that's all the code you have, this window is invalid.

I found various articles about creating and sending emails and about sending attachments.
However I need something simpler: I have an email address and want the resident mail system to create an email with the normal user interaction, i.e. my contribution is only waking the mail service and supplying the address.
It has to be in C++, dialog-oriented (non-SDI, non-MDI).

Have a look at Articles on MAPI. You can't guarantee that a MAPI client is available however.

Thanks, but my program does not have the message content to send.
In fact, I have only an email address in my hand.
|
|
|
|
|
The simpliest way is to use the ShellExecute() function, specifying the email address in the lpFile parameter
ShellExecute (NULL, "open", "mailto:who@where.ever", NULL, NULL, SW_SHOW); You can also specify the subject, cc, and bcc in the lpFile parameter
ShellExecute(NULL, "open", "mailto:who@where.ever&cc=you@them.org&bcc=them@you.org&subject=hello", NULL, NULL, SW_SHOW); If you want to add text or attachments then have a look at SIMPLE MAPI
