Hi,
could you please tell me the advantage of including a file in stafx.h. Does it play a difference role when included in stdafx.h than in other parts of the project?
Thanks In Advance

The difference is that these files only get recompiled if you use "Rebuild All", otherwise they are assumed to be without any changes unless you make these changes from within Visual Studio.
Usually you will include in stdafx.h all libraries and other code that won't be modified by you during development.

|
|
If you change things in a header file (.h), all files that include this header file will be recompiled again because they depends on this file.

Hi All,
Can anyone of you help me out for the below requirement.
I just want to desing an application that has the same functionality as a print application. Meaning that, if I enter the number of pages to be printed in a textboc or so how to manipulate the same internally.
Are there any VC++ classes available for this??
Reply at the earliest please.

You can do this with MFC, see MSDN for CYourStandardKindOfView printing support. Basically, it's about overriding several virtual functions in your view implementation.

Hi,
Sorry 
Can you be more specific in the class name or some thing. The one that you have mentioned "CYourStandardKindOfView" is it a MFC class? I dont find any with this name.
Sorry for the trouble.
Thanks

Does anybody know how to count all the files on a windows environment.
Currently i have a recursive method that goes through all the folders counting the number of files. It takes too long
Any faster method would be appreciated
Thank You

AFAIK this is the only way.

Something makes me think there is no faster way. I mean if there was one why would it take Explorer so long to count the number of files when you invoke Properties command for a particularly huge directory?
Try optimizing your recursive function instead. After all, it gets called over and over again and if by chance it contains unoptimized code... well, it'll slow down for a reason.

Show us the function and maybe we can make suggestions.

Hi there,
I wish to know when printer settings are changed and which printer (in a users session), in a server environment (win2k3), I know about WM_SETTINGSCHANGE but lparam seems to get only "devices" and not the printer name.
What I can do is enumarate all printers and keep track of their DEVMODE and each time the notification WM_SETTINGSCHANGE happens i will enumrate AGAIN all printers and compare with the previous list of devmodes to check if a setting has chhanged. As you can see this is very inefficient.
In your opinion are there other ways to this, at least detect from which user this change has happened, so to check only his/her printers.
Thanks

I made a program that used the gethostbyname(hostname); function in MFC. it worked fine. now when i tried to do the same in a win32 project it is returning null. before this i added the header file "winsock2.h". which showed some errors as redefinition of this xxxxxxx . then i removed it and added the ws2_32.lib reference, after which, it showed no errors but at gethostbyname(hostname); function it returns NULL. have i done anything wrong ? the hostname string contains a genuine hostname. Please answer this

Try to find the error that occurred using WSAGetLastError.
Go through this[^] to find out what happened.

Imediatly after filling a listview with all my data I wish to set the first item as selected.
I use the folowwing:
ListView_SetItemState(GetDlgItem(hwnd,ID_DATA_LIST),0,LVIS_SELECTED,LVIS_SELECTED);
ListView_SetItemState(GetDlgItem(hwnd,ID_DATA_LIST),0,LVIS_FOCUSED ,LVIS_FOCUSED);
This is setting the list item as selected, but it does not give it the focus. i.e. Selected items usualy are highlighted in blue, but mine are simply highlighted in grey until the item is clicked.
Is there something I am missing?

You should have to call the SetFocus function of the list view control.

I understand that I need to use the SetFocus function, but where exactly should it be called?
WM_SETFOCUS // doesn't work
WM_INITIALIZE // doesn't work
When text is being updated within contols via WM_SETTEXT, would that cause a loss of focus? I thought these sort of procedures would pass the focus back if set at all.

u should have to set focus to the list control before you set an items selection state.
SetFoucs(GetDlgItem(hwnd,ID_DATA_LIST));
ListView_SetItemState(GetDlgItem(hwnd,ID_DATA_LIST),0,LVIS_SELECTED,LVIS_SELECTED);

a) There is a style flag for listview that forces it to show selection in blue even when the control is out of focus
b) I guess you can call SetFocus(hwndOfYourListView) in WM_CREATE handler
WM_SETTEXT causes no loss of focus I believe.

If it's a dialog then OnInitDialog
If it's a view then OnInitialUpdate

according to MSDN:
LVS_SHOWSELALWAYS
The selection, if any, is always shown, even if the control does not have the focus.
This is true but it isn't highlighted in blue. Nomatter where I place the SetFocus call, nothing is happening. I have tried before setting item state, after setting state, beginning and end of WM_INITDIALOG, WM_CREATE, WM_SETFOCUS, WM_IMNOTGIVINGYOUFOCUSHAHAHA. Infact the only place it is working is within WM_PAINT, but this is just wrong.
This control is on a dialog along with sevral other controls. The only other thing I can think of is to change the tab order, but still, SetFocus should be unrelated to the tabs.

Is this a dialog? If so then you must return FALSE from OnInitDialog if you are explicitly setting focus or else focus will be set to first control in the dialog.
