when trying to click on a listbox created in runtime over an edit control in a formview, the existing edit control under the listbox control gets a focus. so i can't select an item in a listbox. somebody help me... 
by peng-you.
|
|
|
|
|
hmmmm
try either setting the z-order of the listbox to be in front of the edit control ... maybe destry the edit control ... disable it ... or use a combobox that allows the user to type stuff into the list control portfion and add some custom behaviour to stop the item being added to the list

How can I make my CFileDialog to accept directories and return the full path name of the directory. Something like what I get when I select File / New option in the MSDEV IDE and click on the "..." button next to Location Edit box ??

You don't need CFileDialog for that. Use SHBrowseForFolder instead.

Hi,
If you look on the menu of InternetExplorer:
FILE | SEND -> here you get a popup menu
i need to do the same but do not know how 
m_menu.LoadMenu(IDR_MENU1);
SetMenu(&m_menu);
CMenu* pContextMenu;
//Get sub menu - index 0
pContextMenu = m_menu.GetSubMenu(0);
pContextMenu->AppendMenu(MF_STRING | MF_POPUP, ID_MENU_ADD, "NEW ITEM");
pContextMenu->AppendMenu(MF_STRING | MF_CHECKED, 5001, "NEW ITEM2");
this code will add two new items under the first position in my IDR_MENU1.
How can add new items to position "NEW ITEM2" ?
thank you

In your dialog editor, you do this by checking 'pop-up' for the item, then you can build a menu underneath it. I'm sure it can be done programatically, from memory by adding a menu to another, but I forget the details.

it can be done dynamically. i did it with the following code. (IDR_MENU1 - has only captions of my menu)
m_menu.LoadMenu(IDR_MENU1);
SetMenu(&m_menu);
CMenu* pContextMenu;
CMenu pPopMenu;
//Get sub menu - index 0
pContextMenu = m_menu.GetSubMenu(0);
pPopMenu.CreatePopupMenu ();
pPopMenu.AppendMenu (MF_STRING, 5001, "shortcut to desktop");
pPopMenu.AppendMenu (MF_STRING, 5001, "email");
pContextMenu->AppendMenu(MF_POPUP , (UINT) pPopMenu.m_hMenu , "SEND");
thanks

hi there
i want add an activex control into my project.
its a little bit complicated to explain.
on the start of my program i start all of my windows and minimized them to 0,0,1,1 most of them are CDialog
some CFrame... i dont use mfc ... only a very little bit.
now i want to insert a activex same way. start "minimized" without data. this works. but if i want to insert data. then i hang up.
how can i insert an activex "without mfc" ... or only little little bit of mfc ...
thx

Hi, I'm working with a composite control in Visual C++...
Among other things I have a button on the dialog..
The problem is that I can't get it to react on me pressing the enterbutton.
I've tried overloading the pretranslatormethod but that doesnt work so good....
HELP

Assign the IDOK identifier.
(By default the OK button captures the [Enter] key)

Does anyone know how to pass parameters into an sql command?
Either prompting or just straight in?
Sample code or KB would be very useful.
Thankyou verymuch

catch( CException* e)

}
catch (...)
{
m_pDoc->GetLog()->LogTime();
m_pDoc->GetLog()->Log("\nDATABASE ERROR: Unknown Exception in CCaseDataBase::GetCaseCoverageTypeStatisticsAll()");
}
I took this code out of one of my recent projects, I hope this helps.

CString strQuery = _T("");
strQry.Format(_T(sp_StoretClientFields_ps '%s', %d"), (LPCTSTR)strParam1, nParam2);
//strParam1 is String and nParam2 is numeric.
if you want see:

Here you can see a sample and a class, for use this.

Are there any reusable datetime classes that are freely distributed.
I'm currently using the tm struct & CTime in MFC to work with dates.
I'm looking for a good datetime class with validation on dates built-in.
Thanks,
Gerry.

My dialog agree to apear whole only in specified resulution.
How can I do that its size will be fit to every resulution.
URGENT !!!

The reason it is *urgent* is that you've failed to apply the good advice on this question given several times already.
The function you need to call is called MoveWindow, the function that tells you the size of the screen is GetSystemMetrics, and you can override your OnSize function if you want to move your controls relative to your new window size.
If you find yourself still unable to fix this simple problem with the oodles of help you have recieved, consider posting the code you have written, so we can offer suggestions based on where you are going wrong.

Please! who can show me what I need to change here for that problem
void CRegWinDlg::OnPaint()
{
if (IsIconic())
{
CPaintDC dc(this); // device context for painting
SendMessage(WM_ICONERASEBKGND, (WPARAM) dc.GetSafeHdc(), 0);
// Center icon in client rectangle
int cxIcon = GetSystemMetrics(SM_CXICON);
int cyIcon = GetSystemMetrics(SM_CYICON);
//this->MoveWindow(cxIcon, cyIcon, m_hIcon, true);
CRect rect; //this->MapDialogRect(&rect);
GetClientRect(&rect);
int x = (rect.Width() - cxIcon + 1) / 2;
int y = (rect.Height() - cyIcon + 1) / 2;
// Draw the icon
dc.DrawIcon(x, y, m_hIcon);
}
else
{
CDialog::OnPaint();
}
}
|
|

The paint handler effects how the area is painted, not how big the dialog actually is. The handler under the check for IsIconic draws the icon.
You need to over ride OnInitDialog, where you can do what I suggested ( get the dimensions using GetSystemMetrics and call MoveWindow ), although MapDialogRect looks like a better idea, I have never used it before so I cannot comment. ( I intend to though, it looks useful ).
I'd suggest trying MapDialogRect first, and doing it in OnInitDialog.
Christian

I did so and this problem remain
BOOL CRegWinDlg::OnInitDialog()
{
CDialog::OnInitDialog();
// Set the icon for this dialog. The framework does this automatically
// when the application's main window is not a dialog
SetIcon(m_hIcon, TRUE); // Set big icon
SetIcon(m_hIcon, FALSE); // Set small icon
int cxIcon = GetSystemMetrics(SM_CXICON);
int cyIcon = GetSystemMetrics(SM_CYICON);
CRect rect;
MapDialogRect(&rect);
//GetClientRect(&rect);
int x = (rect.Width() - cxIcon + 1) / 2;
int y = (rect.Height() - cyIcon + 1) / 2;
CPaintDC dc(this); // device context for painting
// Draw the icon
dc.DrawIcon(x, y, m_hIcon);
//this->MoveWindow(cxIcon, cyIcon, x, y);
}

I'm not sure why you expect this to work, but I'd suggest that when people give you advice you seek to learn *how* something works so that you don't have to ask again. You have copied a lot of code that came for free in your OnPaint, which, as I explained before, has nothing to do with what you want.
Here is the total solution. Please take the time to understand how it works, it is with the hope that people will *learn* that I spend time here answering questions.
MoveWindow(0, 0, GetSystemMetrics(SM_CXFULLSCREEN), GetSystemMetrics(SM_CYFULLSCREEN));
This moves the window to fit exactly onto the screen - you will probably have to subract from the last parameter in order to allow for the taskbar. I am not sure at this late hour how to go about figuring out the available screen area taking into account the taskbar - read up on GetSystemMetrics, it's probably there. Also, all of your individual objects in the dialog will remain where they are relative to 0,0 and may need to be resized. They can have MoveWindow called on them as well, by default they are derived from CWnd.
Hope this helps.

If I have an EXCEL file and I want the VISUAL C program to read data from that EXCEL file....Do you know how to do it?........I have tried the function fopen but they said I put the source code at the wrong function or something like that do you have any idea?
Thank you

Have you tried using the ODBC Excel Driver found under System DSN. At least it is there on my machine, I believe from the instalation of VC++. You should then be able to access like a database using CRecordSet derived class.

I have an OpenGL application app based on MFC. I have a requirement that I need to redraw the whole scene every second(some sort of animation). When I use the standard method of invalidating the client area every second, the CPU usage is very high and my app does not respond to any other commands.
Can someone suggest any better ideas?
Thanks
