Only some CSIDLs are supported with SHGetFolderPath(), and CSIDL_DRIVES is not one of them. You can, however, use CSIDL_DRIVES in conjunction with SHBrowseForFolder().

Hi
When I try to open .vcprj files which were created by converting c++ prjects I get this error: "The application for project '<project name="">.vcproj' is not installed. Make sure the application for the project type (.vcproj) is installed"
I have been expermenting with addins for the last couple of days, and handled the registry myself (for cleaning addin leftovers) so I probably erased one tto many registry entries.
Could you help me restore the right entry?
Thx

Hello everyone:
How to get back color of a dialog? Please help me.
Thank you.

In OnInitInstance you can call SetBkDialogColour(i am not sure if the syntax is right) maybe there is a function also for getting the background color.
|
|
|
|
|
Have you looked at GetSysColor()?

Great! What COLOR_xxx value did you end up using?

Hi
I did as the following:
GetSysColor (COLOR_3DFACE)
I hope it can be useful for you.

rresponding category.Attached to
the definite category in the tree in the list
on the right side the goods of this
category have been appeared.The window of
adding of goods is called by right click
of mouse in the right window and the window
of adding of category is called
by right click of mouse in the left window.

Ok, so which part specifically of this overall design are you having trouble with?

Hello,
I created a class inherited from CBitmap to add some functionality like rotation, blur and so one.
Now I need to create a function that changes the color depth of the bitmap.
I need to convert the 24 bpp color bitmap into B/W, 8, 16, 256 Colors and 16 bpp I also need a function that converts from all the above color's depths to 24 bpp bitmap, the function perform save directly.
Any ideas
thanx in advance
Enjoy.
Ouss.

That u fnd dsgning toolbrs in th rsrc-edtr 2 dffclt & instd wanna do it mnlly snds lke a bad wy of lrning.
The toolbar is a bitmap and a part in the resorce file (*.rc). If you want to see how it works, create a simple project with a toolbar. Then open the rc-file as text (it is a textfile) and search for your toolbar ID - if you have changed it, or just the word "toolbar". You'll see that it is composed of a bmp (that you can edit with another paint application), and a TOOLBAR-resource. You'll immediately understand the syntax

maybe it's an option to create one in the resources and customize it later? You can add-remove buttons, set a location, change the bmp's ......
using BMP's or ICON's is easy, you can use a CImageList.
Good luck.

Can anyone please tell me why "C" and "C++" does not support nested functions?
|
|
|
|
|
Haven't you asked this before? What is a "nested function" -do you mean where you define a function inside a function, givinge the inner function access to the outer function local variables? Have you ever maintained such code? Then you don't need to ask
|
|
|
|
|
I have not used such a code defining function inside function. but i am eager to know why such a thing cannot be done. wht r the problems tht we come accross. does ur statement "givinge the inner function access to the outer function local variables" hold true?? I may sound silly, but i want to get it clarified.

Of course it can be done, you just redefine the language

It is you asking about nested functions, I have no idea if you mean the Pascal flavour of this (slightly bizarre) concept. They give access to the local variables in the "function parent".
Why isn't this included in the C++ language definition? Who knows, I wasn't consulted - and if I had been, I had most certainly advocated against it
It leads to long and difficult-do-read functions, giving functionality that can be replaced by other constructs.
|
|
|
|
|
It does. Just put a class within another class, and hey presto - instant nested functions.
|
|
|
|
|
Probably because it is never necessary to have such a construct in C++.

In MFC,can somebody explain me how the mapping takes place.I mean where does the info comes -list of messages?
Does it come from a database?
I know that DECLARE_MESSAGE_MAP() creates 3 entries.
One of which is structure of array which consists of eventsid and functions call.
|
|

hello blacktiger
mapping of messages happens in the message map (im not trying to be smart it really does )
DECLARE_MESSAGE_MAP is only half the story
in your cpp file there is something like this
BEGIN_MESSAGE_MAP(FxMarginsDlg, VDialog)
//{{AFX_MSG_MAP(FxMarginsDlg)
ON_BN_CLICKED(IDC_BUTTON_CLOSE, OnButtonClose)
//}}AFX_MSG_MAP
END_MESSAGE_MAP()
this is the message map. Entries are added by the Wizard in Visual Studio or you can edit it manually.
In this example the control with ID IDC_BUTTON_CLOSE is mapped to function OnButtonClose
Your best bet in understading how this works is to insert a command in an empty app, add a handler as above and set a breakpoint in the handler function. When the code hits the breakpoint you can look at the call stack and trace into the MFC code.
Hope this helps

How should I map my own events and notifications in MFC?
In my app I created a Dialog box in a SDI app where I have events in one Combo Box and Notifications in another Combo Box?
Now I wish to map events and notifications,
How should I proceed?
|
|
|
|
|
Events and notifications are really different names for the same thing. I would recomend you spend some time reading MSDN and online tutorials or a good Win32 programming book.
