If you are bent at using crt routines, then _chdir would do that. Be aware that this routine would internally call the win32 api, SetCurrentDirectory.

SetCurrentDirectory(for set directory)<br />
GetCurrentDirectory(for get current directory)

We recently switched a rather large project (7 projects in this workspace) from VS2002 to VS2005. This was in anticipation of supporting 64-bit apps, so we had a lot of details to straighten out before we had a working build.
Once the dust had settled, I realized that the browse info for the system no longer works. Whenever I click a symbols name and press F12, for a symbol defined in one of our projects, I get the message "The symbol 'whatever' is not defined." Symbols defined by MFC are handled correctly.
Now, the wierd part: the settings for browse info are all correct, as far as I can tell; I get the correct progress message when thge browse info is created; and the browse info files are where they should be (in the same directory as my .objs). But for some reason, VS2005 can't find them!
Any idea what might be wrong here?

I am dynamically adding content to a CDialogBar - when the on-screen capacity is reached i want to add a scrollbar to allow the content to be visable.
I understand that CDialogBar will not allow a Scrollbar - so i'm not really sure what to do. I'm quite limted with a CDialogBar as i need it as part of MDI.
Any help appreciated!

I was trouble by this problem for a long time!
I insert a new dialog template which ID is IDD_DLG_MYDLG
and create a new dialog class named CMydlg;
and I use this dialog in my application :
ex:
void CMyapp::showDlg(CString str)<br />
{<br />
CMydlg *dlg=new CMydlg;<br />
dlg->Create(IDD_DLG_MYDLG, this);<br />
dlg->ShowWindow(1);<br />
dlg->SetWindowText(str);
}
Now, I click one button to show my dialog
ex:
void CMyapp::showMydlg(void)<br />
{<br />
showDlg("my dialog 1");<br />
showDlg("my dialog 2");<br />
}
then, I want to know that the first dialog I created is close or still active,
I don't know how to specify that the dialog , which has some mark to specify it, or else , I use the function showMydlg, it will create lots of dialog, I want to show it if it was not created, or create it if it is not showing!
if some one know ,please tell me , it was so trouble thing, that some one use my application, who continuously clicked one button , so many dialog show make me shy!
if you know what I mean , please give me a better way to solve it !
waiting for answers online!

First, the problem with your code is that you have a pointer local to a function (the CMydlg *dlg pointer which is in showDlg). You allocate memory for this pointer but when you reach the end of the function, you don't have any grasp over the pointer anymore. Thus, this will result in a memory leak. Instead of making it local in the function, make it a member of your class (CMyapp). This way, you can control if this dialog is already created (pointer points to a valid dialog class) and you can retrieve the status (if the dialog is visible or not).
And, furthermore, there is no need to make it a pointer, just show/hide it with the CWnd::ShowWindow function.

I know what you mean, you say that I make it a member of my dlg class.
that creating it when I use it ,and assert it , and show it correctly,
is it?
But the problem is that :
I create a CListCtrl,
and add many item at it !
You know the ICQ:
I simulate it ,
when I dbclicked one item, show a dlg(this dlg is diffrent by its content),
If I dbclicked the same item, show the dlg I just created!
but if the list has so many items, ex 1000,
shall I prepare 1000 pointer at my application as a member at a class?
so I want to find a way that I want to create it when I want to show it !
just I want to decrease the class member pointer!
If it's no way , I think I only use dlg* mydlg[1000] to solve it !

So, you have also 1000 different dialog templates ? 
Or is it the same dialog but with different data in it ?
In the latter case, you can simply pass the data to the dialog before making it visible.

I think it so long time, does the clist or ctypedptr can solve it?

hi i had written the code to block the specific port using packet filtering API,all work fine but "Pfbindinterfacetoindex" execute successfully but did not block the port so i googled and find another API pfbindinterfacetoindex but it still fails the only problem could be here where give index
GetIpAddrTable( NULL, &dwIface, FALSE);
pIpTable = (PMIB_IPADDRTABLE) malloc(sizeof(PMIB_IPADDRTABLE));
GetIpAddrTable(pIpTable,&dwIface,FALSE);
for (pIpAddr = &pIpTable->table[ dwIface = 0]; dwIface < pIpTable->dwNumEntries; ++dwIface)
++pIpAddr;
PfBindInterfaceToIndex(ihandle,pIpAddr->dwIndex,PF_IPV4,(PBYTE)ip);
tell me what is wrong with this why this is not working i had spend atleast a 1 and half week on that but was failing.

Maybe instead of
GetIpAddrTable( NULL, &dwIface, FALSE);
pIpTable = (PMIB_IPADDRTABLE) malloc(sizeof(PMIB_IPADDRTABLE));
. . .
you should try this:
dwIface = 0;
GetIpAddrTable( NULL, &dwIface, FALSE);
pIpTable = (PMIB_IPADDRTABLE)malloc(dwIFace);
. . .
I hope it helps.

My project's Classview has become cluttered with a lot of classes and global functions. Many of these are used internally by a component. Is there a way to remove the ones from Classview that I find unnecassary. I am using Microsoft eMbedded Visual C++. Thanks for any help.

You can create folders in ClassView - right-click the project and select New Folder. You can then drag classes into the folder. Unfortunately you can't manage global functions in this way.
An alternative is simply to remove the headers from the project. They aren't required to be part of the project in order to compile - dependency analysis will pick them up. Obviously you should not remove them from source control, if you're using IDE integrated source control.

Hello comunity,
i use an COleSafeArray to write data to an excel file, and this works fine, but seems like they(data) are not sorted!
Is there any way to sort an COleSafeArray?
Thanks!

Sort your items before putting them in the COleSafeArray container, or use Excel's automation features to sort the items after they are stored in the xls file. COleSafeArray doesn't have any built-in sorting functionality.

hi all
how to capture mouse movement over button event. Specifically i need a event when mouse moves over a button and another event when it goes away from that button.
I am doing this in Win32 C based application.
If u have any link to sample code pls specify that.
Thanks

have a look at _TrackMouseEvent
|
|
|
|
|
I am using this function, but not getting event when mouse moves over button.
The code i am using is,
TRACKMOUSEEVENT track;
track.cbSize = sizeof(TRACKMOUSEEVENT);
track.dwFlags = TME_HOVER | TME_LEAVE;
track.hwndTrack = bHandle; //handle to the button
track.dwHoverTime = 1000;
_TrackMouseEvent(&track);
And i am checking WM_MOUSEHOVER, WM_MOUSELEAVE messages.
Is it correct. thanks for ur suggestions.

You've not provided nearly enough information. For starters, what code do you have in place to create/display the dialog?
