Something like ::OpenStreamOnFile(...)?
Peace!

How could I have missed that? I been searching like crazy.
And after search for the one you gave me I also found SHCreateStreamOnFile that is even better.
Thanks !

Just be sure to pay attention to the minimum shell version required for SHCreateStreamOnFile...!

I'm having trouble getting the date when the user picks a date from the drop down calendar.
I added the control as an activex control to my dialog box. i created a member variable to it. So now i want to retreive the date. I created by events and they work. When a user picks a date from the drop down calendar it drops to that event. But I'm not sure how i get the date back from the control.
Thanks

hiho@ll
i need some resources (tutorials, ...) for CDO programming using C++
i want to sync apointments/calendar and contacts with an web application (most programmed in php)
i found a interessting project here for outlook, to read the contacts and mails, ...
but i need some infos about writing such contacts back to outlook and doing both (reading and writing) using the exchange server
i found only a few articles which helped me not much for this (caus, i'm at a beginning level in CDO)
so, anybody knows good resources for tips, tutorials (or a opensource prog, which does the sync for me!?)
thx@ll

Is there any way to display window created in another application inside the frame (window) in other application. Circumstances are:
- Application obtains frame-applications window handle with FindWindow(...)
- Application (MFC) creates a window (CDialog ancestor) with Create and gives queried handle as a
parent parameter
- Application notifies frame-application with PostMessage that window is created. frame-application then tries to move the window in right position inside its frame
Dependding on tricks (SetParent, SetPos etc...) best I can do is that window appears inside
frame-applications frame in weird location and does not move regardless what I do. Window is also
not displayed properly (transparent caption etc...)
In general (if possible) what would be a proper way to achieve this kind of behauviour ?

I like to do a component ActiveX with the following characteristics:
-a method carried a file
-the information of the file were presented in a propertysheet for alterations
-the propertypage didn't have size restriction
-the file was returned to who called the ActiveX
For that I have as tools:
Visual C++ 6.0
After researching in the internet I verified that the information on propertysheet inside of component ActiveX are confused. If it was
possible to present a sample with the general idea of as to do this I would be thankful.

I have class, all of my database functions are in it. I wonder, using all these functions as static and calling them staticly or make it as standart object and declare it in document class and call the functions by GetDocument()->....
which one is better? What are the advantages of static funtions?
|
|
|
|
|
Static functions in a class means that they are 'not bound to a particular instance of the class'. That means you can call this function directly like that:
CMyClass::StatFunc();
In fact the function is 'shared' across all instances of the class. But that also means that inside this function, you cannot make call to other non-static function of the class or use non-static member variables of the class. So I really don't understand what you try to achieve by doing this ? 
Why don't use a normal class for doing that ?
|
|
|
|
|
Just i thought if there'll be a large class full of functions (all database part take place in this func) may use a lot memory, so i thought that may be it is better to call them staticly so there wont be an object in memory everytime.
|
|
|
|
|
If the function itself is not written well and it abuses memory, it is going to do so regardless of being a normal class member or a static member.
If you end up having static data members used by the functions, make sure you protect them against concurrent access if you have multiple threads running.

I guess its better using classic functions.
|
|
|
|

Why is it better to use classic functions? If you don't need "this", don't use it. Make the functions static, that is what they are. If they need to call non-static methods, then your class isn't well defined. If you have static variables in these static methods, then your class isn't well defined.
If you don't need "this", make the routine static. If you do need "this", make it a thiscall. Use the right thing in the right place.

I'm going to patent thought. I have yet to see any prior art.

"Better" is a subjective term. Static and non-static methods each have their place. It all depends on the nature of the problem.

Look into the Singleton design pattern and see if that will work for you.

Hello,
i´m trying to create a program that creates several independent windows with CreateWindow, each one will handle it´s own events, and will run completely independent, and i don´t know how to create all the windows, i tried with several CreateWindow in the WinMain, but the second window is created only if the first is closed, and the same with rest.
How can i do this, creating several threads or there is a way to create a window with the event loop, but return the control to the main application?
|
|
|
|
|
Why not create a number of CWinThread objects, and let each one run its own window message pump - just make sure that the primary thread (that creates the others) sticks around until the other threads terminate.

Hi,
I need help on passing arrays from VB to VC++ function through a macro written in VC++. I want to pass an empty array by reference from VB to a VC++ function and modify the ubound of the passed array in the VC++ program. Can I redimension the empty array within VC++. Can I get back multidimensional arrays.
Thanks in advance.

pls help me in my trouble.i want to convert double value to ascii.can u give code for that?if it is not possible how can i do it?

<font color=blue>double</font> d = 5.4E3;
<font color=blue>char</font> str[50];
sprintf(str, <font color=gray>"%f"</font>, d);

MFC:
double dblValue = sqrt(2);
CString csText;
csText.Format("%f",dblValue);
C:
char Buffer[256];
double dblValue = sqrt(2);
sprintf(Buffer,"%f",dblValue);
|
|
|
|
|
%g or %f in sprintf:
%f => double Signed value having the form [ – ]dddd.dddd, where dddd is one or more decimal digits. The number of digits before the decimal point depends on the magnitude of the number, and the number of digits after the decimal point depends on the requested precision.
%g => double Signed value printed in f or e format, whichever is more compact for the given value and precision. The e format is used only when the exponent of the value is less than –4 or greater than or equal to the precision argument. Trailing zeros are truncated, and the decimal point appears only if one or more digits follow it.
Extract from MSDN doc.

This makes no sense. With the exception of Unicode, all of the characters, numbers, and symbols you can type are ASCII. There is no such thing as converting from any of those to ASCII. Please explain further what it is that you are attempting to do.

CString sr=m_edit6.Left(3);
//ch=sr.GetAt(0);
char *t;
double dt=::strtod(sr,&t);
CString str1;
str1.Format("%g",dt);
MessageBox(str1);
this str1 contains a double value.i want to convert this double value into its ASCII value.plz help mw with this.
|

|

Why the extra step?
sr --> dt --> str1 
How about:
str1.Format("%g", (LPCSTR) m_edit6.Left(3));If you need the intermediate step, why not use atof() instead of strtod()?

Let me see if I have this right. If str1 contains the value 123.45, what exactly is it that you want it converted to? The ASCII value of 1 is 49, 2 is 50, etc. The ASCII value of the decimal is 46. How are you wanting to store these values?
