ok thx,
I saw it in an example about how to use GDI+ to manipulate images, but there were no information that it was in CLI/C++.

If you find managed GDI+ code samples you can generally (if not always) translate them
into native C++ code with little difficulty. The class names are the same, some native GDI+
methods are properties in the .NET classes but the names are very similar.

Try asking at: CLI/C++[^]

Hi all,
How can I (with the use of C++) change the system volume? Like configuring a slide bar and as the bar changes the volume changes ... somelike that. What functions can I use?
Thanks in advance

USE Windows SDK functions
MMRESULT waveOutSetVolume(
HWAVEOUT hwo,
DWORD dwVolume
);
MMRESULT waveOutGetVolume(
HWAVEOUT hwo,
LPDWORD pdwVolume
);
Use NULL in to the HWAVEOUT hwo parameter.

hi,
I want to scroll window when someone press tab on text box. my problem is i have dynamically generated textboxes in a window and window size is fixed. so when there are more then 10 text boxes i am giving a scroll bar and allows user to scroll through the textboxes to enter the values. i want to allow users to press tab and go through all text box. so when user is at last visible text box and press enter, scroll bar should automatically scroll one textbox down.
how can i archive this ?? please help.

If you make your text boxes of a class you have derived from CEdit, then you can handle the WM_SETFOCUS message to know when a new edit box has gained focus after the user pressed tab.
Since you now know which edit got the focus, you can use GetWindowRect() (followed by ScreenToClient() on the window that holds the edit boxes), and compare this to your window's client rect - *after* the current scroll position has been used to offset the top and bottom of the window's rect. This will tell you if the new edit control is visible; if it is not, you can determine which way to scroll to bring it visible. This can be achieved by calling SetScrollPos() on the scroll bar.
I'm assuming you are comfortable with moving the edit controls to simulate being scrolled?

Thanks for ur Response,
I had tried LVN_ITEMCHANGED event. I write following code in MASSAGE MAP
as
BEGIN_MESSAGE_MAP(CSelectBusCategory, CPropertyPage) // Line 1
//{{AFX_MSG_MAP(CSelectBusCategory) // Line 2
LVN_ITEMCHANGED(IDC_PREVIEWLISTCTRL, OnSelectItemFromList) // Line 3
//}}AFX_MSG_MAP Line 4
END_MESSAGE_MAP() // Line 5
I also write definition for it as
void
CSelectBusCategory::OnSelectItemFromList(NMHDR* pNMHDR, LRESULT* pResult)
{
MessageBox(" Hiii");
}
When I compile this code, I got error in between
BEGIN_MESSAGE_MAP and END_MESSAGE_MAP(). These are
1)term does not evaluate to a function (Line 3)
2)syntax error : ';' (Line 5)
3)missing function header (old-style formal list?) (Line 5)
4)syntax error : missing ';' before '}' (Line 5)
5)syntax error : missing ';' before '}' (Line 5)
I could not find the reason why these errors are occure though the syntax are correct.I have solution then plz forward it.
Thanks in Advance

The proper way of handling a notification message is likewise
ON_NOTIFY(LVN_ITEMCHANGED, IDC_LISTID, OnListSelectionChanged)

Thanks Nibbu,
I can capture the select item event. Now I want to get the item text so for this I write following code in message function but returns me blank string. The code is as
CString strJPEGFileName = " ";
int nItem,nSubItem;
strJPEGFileName = mWebPagePrvListCtrl.GetItemText(nItem,nSubItem);
Is there any method to retrive text data of selected item.
Thanks in Advance

I am using VS2005 for VC++ application, and my solution contains many projects. I added project to source control using VS2005 "Add projects to source control" menu. It added all *.h & cpp files. But some other files having named "*.vcproj.vspscc" also got added to source control. Why? what is use of this file?
Also what all files from VS2005 project & solution to be added to VSS? I mean which files excluded from Adding to VSS, for a smooth working of group of people in a solution/project
Thanks
Anil

For Visual Studio 2005, you need to add these files to the source control (and of course, all your .cpp and .h files):
- .sln file: contains the information about the different projects that are in the solution. So, if someone adds or remove a project from the solution, it should be 'saved' for others also.
- .vcproj files: contains all the settings for each projects (you will have one vcproj file for each project). This contain for example the files that are in your project (so if someone adds a new file, it should be reflected), contains also the project properties (all the option that you can configure by clicking 'Project' -> 'Properties').
All the other files are not needed and will be automatically recreated.
