Hi all,
I recently wrote some code for a company to import contacts into Outlook from an access database. This cannot be done via Import.
My problem is that with the VBA code running at a stupidly slow speed through a macro I decided to use Visual C++ and automate Outlook. It runs much better but I have one problem, how do I add extra user properties to an outlook contact?
The code in VBA is:
Set Prop = c.UserProperties.Add("Yours", olText)
How do you do it in C++ though?
Any help appreciated.
Cheers,
James.

Anyone know hot to check a machine to see if IIS is installed programatically? A CD we're putting together for a customer has several installs on it and so they've requested it have a little pop-up (autorun) with buttons for installing each. Sure, no problem. However, I'd like it to do some of the checking for me as well and recommend things they need to install that I can't package with the CD (like IIS). So, I want to try and determine whether IIS is already installed... Same question for PWS?
Thanks in advance.

Hello, the codegurus around the world.;)
This job is related to your problem solving skill.
Maybe, we find the answer in MSDN knowledge base soultion.
Otherwise, you may find the answer by yourself.
I guess that IIS and PWS are the system level of application, and
we can't change the installed directory.
Even though we can change the installed directory, we can find the
customized installed directroy in the registry.
So, as far as I am, I try to check the exe file or DLL version of
each IIS or PWS.
But, this is another problem. When I upgrade from NT worksation with PWS to Windows 2000,
I found that PWS and IIS coexists. Ooops.
In this case,
Please, don't send me your email about your questions directly.
Have a nice day!

Hi all, I want to round a float/double number (to an integer)so that when its less than number.5 it is rounded down and when its greater than or equal to number.5 round up. At the moment I have discovered ceil and floor, but these are no good, as it is an either or solution. VB has a dedicated round function, is there one in VC++?
cheers all
Alan.

Why don't you use sprintf? Here's two functions. One returns an int (after rounding), and the other returns a double after rounding to the nPrecision'th decimal point.
int _rounder(double n)
{
char st[16];
sprintf(st, "%.0lf", n);
return atoi(st);
}
double _rounder(double n, int nPrecision)
{
char st[16];
sprintf(st, "%.*lf", nPrecision, n);
return atof(st);
}

As far as I know, there's no "round" function, but here's a modified version of the one I use:
#include < math.h >
double round(double dValue, unsigned uDecimalPlaces)
{
dValue *= dValue;
dValue += 0.5;
dValue = floor(dValue);
return (dValue / pow(10.0, uDecimalPlaces));
}

Thanks for the responses guys! You solved my problem! All I needed to do was add 0.5 on and then floor it because that would, in effect round it exactly how I want it.
Many, many thanks

Hi, everybody, i need some help for writing an operator=
:::::::::::::::::::::::::::::::
class aa
{
public:
int var;
virtual aa& operator=(const aa && c ) throw();
};
:::::::::::::::::::::::::::::::
class bb : public aa {
public:
int varbb;
bb& operator=(const bb && c )
{
varbb=c.varbb;
return *this;
};
};
int main()
{
aa * xx = new bb();
aa * yy = new bb();
*xx=*yy;
};
Problem:
Ok, so when i execute this code "*xx=*yy" the aa operator= was called, but i want to use the bb operator=.
How can i do that?
Ho, sorry for my english.
|
|
|
|
|
In that case you must declare the operator in class bb the same way than
in class aa. Did you notice that they are not compatible?
They both must be virtual. (In fact, that's the first time I saw someone
using virtual operator but hey, it's good to know. Thanks).
|
|
|
|
|
Since the bb operator is not declared exactly as the aa operator, they're not treated polymorphically. In other words, they appear as two different functions and the compiler uses the one that most closely matches.
Regards,
Alvaro

|
|
|
|
Ok , thank's a lot
But do you know the solution for my problem.
|
|
|
|
|
The solution is to add another assignment operator inside bb that looks exactly like the one in aa. Then you can call bb operator from there by casting the parameter to bb&:
virtual aa& operator=(const aa& c) throw()
{
return operator=((bb&)c);
}
Regards,
Alvaro

|
|
* reinterpret_cast<bb *>(xx) = * reinterpret_cast<bb *>(yy);

Thank's, but sometimes i don't know the real type of xx and yy, and i dont want to know.
I don't write this code with a switch.
Other idea ?

Can operators even be virtual? You certainly can't make = virtual, because = always operates on a object, not a pointer to an object, as is required for polymorphism.

Hello experts,
Well,I have a VC++ 6.0 developed application, supporting MBCS, which is the default for VC++ 6.0. Also, let me tell you I am using Windows 2000 platform.
Then, I have compiled it with UNICODE MFC dlls and static librarys[ UAFX*.lib and Unicode MFC dlls] and got the UNICODE version of application.
Now, my requirement is to develop one single application that can support both Unicode and MBCS[DBCS]....
Well, I dont know wehether this is possible, if Possible, please let me know how to go for.
Thanks & Regards,
Mr Prasad G.

While I'm not an expert, I will try to answer your question.
Use the TCHAR macro's for all your string manipulations (CString does this)
ie.
use 'TCHAR' instead of 'char' or 'WCHAR'
use '_tcscpy' instead of 'strcpy', '_mbscpy', or 'wcscpy'

I wrote database program,and my m_pSet(recordset) is snapshot and I can use AddNew() function;when I change m_nDefaultType to dynaset I can't use AddNew() and when I use CanAppend() it does not append!
How can I add a new record to dynaset record?
thanks
|
|
|
|
|
You only can set the type of recordset in the openrecordset. Is for this that the only way is close the recordset an open again, using a dynaset type...

Hi !
I have an app using the Doc-View architecture.
In my View class, I have a method GetDocument().
I would like to be able to access the document from my mainApp class, not from the view. GetDocument() is using the member property m_pDocument, but I cannot use it from my mainApp class. How can I get a pointer to my CDocument class from my App class ?
Thanks for your help !

How do I get those nice blue/white buttons and dropdown menus that most XP applications use in my MFC app?

Hi, All !!!
=======
Last time I asked: How to grayscale a picture, and didn't got an answer.
Well...
If you guys wanna know how, there is your answer:
I found out that in order to have a gray color,
all Red,Green & Blue must have the same value.
So...
<code>void</code> GrayscaleIt(MyPicture & pic)
{
for (<code>int</code> y=0; y<pic.height; y++)
for (<code>int</code> x=0; x<pic.width; x++)
{
<code>COLORREF</code> col= pic.GetPixel(x,y);
<code>unsigned char</code> gs= ((GetRValue(col)+GetGValue(col)+GetBValue(col))/3);
pic.SetPixel(x,y, RGB(gs,gs,gs));
}
}
BTW:
I have a question.
After the win32 AppWizard, In order to make my window "transparent" or "hollow",
I need to change the wcex.hbrBackground to 0 ;
Like this:
ATOM MyRegisterClass(HINSTANCE hInstance)
{
WNDCLASSEX wcex;
wcex.cbSize = sizeof(WNDCLASSEX);
wcex.style = 0;
wcex.lpfnWndProc = (WNDPROC)WndProc;
wcex.cbClsExtra = 0;
wcex.cbWndExtra = 0;
wcex.hInstance = hInstance;
wcex.hIcon = LoadIcon(hInstance, (LPCTSTR)IDI_GRAY1);
wcex.hCursor = LoadCursor(NULL, IDC_ARROW);
<code> wcex.hbrBackground = NULL;
wcex.lpszMenuName = NULL;
wcex.lpszClassName = szWindowClass;
wcex.hIconSm = LoadIcon(wcex.hInstance, (LPCTSTR)IDI_SMALL);
return RegisterClassEx(&wcex);
}
How do I do it in MFC ?????
Please, HELP!
BTW: come to #CodeProject on DalNet (mIRC)

Take a look at PreCreateWindow, which you can override in your CMainFrame class.

Call AfxRegisterWndClass() and save the returned string. Use that string as your window class name.
