Sorry to have to ask these, but Project Sheets (and working with tabs in general) is completely knew to me and the MSDN is vague on some of these things.

Okay, so I have my Property Sheet set up and I've added 5 Property Pages to it. In each page is a list control (report style) that has to have headers for each column. I can set the headers with the first one (PropertyPage) but none of the others (PropertyPage1, PropertyPage2, etc). Is there something that I'm missing as how to reference those particular pages?

Next, adding buttons (yes, I asked this before; sorry for the repeat question). I know how to create the buttons, but for some reason they're not showing up in the Propery Sheet at all. I don't want buttons in the Property Pages, but rather outside of them on the Sheet itself. Right now, it looks something like this:

pWnd = GetParent();
m_btnRead.Create("Text Goes Here", WS_VISIBLE | BS_PUSHBUTTON, CRect(10, 50, 100, 208), pWnd, 1);

I've also tried replacing "pWnd" with "this". Nothing. No button anywhere. Again, am I missing how to correctly reference the Sheet?

Any help is greatly appreciated.

How and where are you inserting the columns in each list control?

For the first Property Page, I have this:

m_lstPage1.InsertColumn(0, "Text here", LVCFMT_CENTER, 50, -1);
m_lstPage1.InsertColumn(1, "Text here", LVCFMT_LEFT, 100, -1);
m_lstPage1.InsertColumn(2, "Text here", LVCFMT_CENTER, 100, -1);
m_lstPage1.InsertColumn(3, "Text here", LVCFMT_CENTER, 100, -1);
m_lstPage1.InsertColumn(4, "Text here", LVCFMT_RIGHT, 100, -1);
m_lstPage1.InsertColumn(5, "Text here", LVCFMT_CENTER, 100, -1);
m_lstPage1.InsertColumn(6, "Text here", LVCFMT_CENTER, 100, -1);

Now, if I try to say something like:

m_lstPage2.InsertColumn(0, "Vol #", LVCFMT_CENTER, 50, -1);

I get an error that says "m_lstPage1 : undeclared identifier" even though it is declared.

But where are you trying to insert these columns from?

Oh.

Here's the code:

BOOL CPropertyPage::OnInitDialog()
{
CPropertyPage::OnInitDialog();

// TODO: Add extra initialization here
SetColumnHeaders();

return TRUE; // return TRUE unless you set the focus to a control
// EXCEPTION: OCX Property Pages should return FALSE
}

void CPropertyPage::SetColumnHeaders()
{

m_lstPage1.InsertColumn(0, "Text here", LVCFMT_CENTER, 50, -1);
m_lstPage1.InsertColumn(1, "Text here", LVCFMT_LEFT, 100, -1);
m_lstPage1.InsertColumn(2, "Text here", LVCFMT_CENTER, 100, -1);
m_lstPage1.InsertColumn(3, "Text here", LVCFMT_CENTER, 100, -1);
m_lstPage1.InsertColumn(4, "Text here", LVCFMT_RIGHT, 100, -1);
m_lstPage1.InsertColumn(5, "Text here", LVCFMT_CENTER, 100, -1);
m_lstPage1.InsertColumn(6, "Text here", LVCFMT_CENTER, 100, -1);

}

This is all inside the Property Page class.

I think I got it figured out. I needed a separate function for each page in the Property Sheet.

But I'm still having a problem with placing buttons on the Property Sheet. No matter what I do, the button will not show up.

Any ideas or suggestions are appreciated.

Correct. For each page/tab on the sheet, a separate CPropertyPage object is needed.

You need the WS_CHILD style, WS_TABSTOP would also be helpful if you want to be able to use the tab key to get to your buttons. Also, make sure the rect you specify is in your sheets client coordinates, and not off the sheet somewhere.

Hello gurus,

I would like to know how to read and write bytes on a USB connection device?

I do ::CreateFile(strUsb, GENERIC_READ|GENERIC_WRITE, 0, NULL, OPEN_EXISTING, 0, NULL) where strUsb contains the path to the port "\\.\[path] I obtain my handle, then when I try to read and write bytes via ReadFile and WriteFile, nothing happens.

Can any one show me how to read and write bytes on a usb port?

Thanks.

Best regards.

Switch between Unicode and ANSI

Hi,

I've got a project where for some reason unicode support is turned on in the code, I've come to this conclusion because it is using the "W" versions of certain functions. I've done a search for #define UNICODE but didn't find in the code. I don't see an option for this in the Visual Studio Preferences either. Is there another way to turn it off?

Thanks

Did you search for both UNICODE and _UNICODE in the .h, .cpp and .dsp files?

Yes I searched for both UNICODE and _UNICODE.

I found it!!

My project was generated by another program and it set the Preprocessor define UNICODE in the project. So it was in the Project Properites setting under C/C++ > Preprocessor > Preprocessor Definitions. This is the reason it didn't show up when I searched the code for #define UNICODE.

Thanks for the help!!

You EnumWindowsProc function is declared wrong. It has to be either a global function

BOOL CALLBACK EnumWindowsProc(HWND hWnd, LPARAM lParam)

or a static class member

static BOOL CALLBACK EnumWindowsProc(HWND hWnd, LPARAM lParam)

//Get Desktop window Title

            Str.Format(\"%s\",lpString);

Add buttons to a Property Sheet

bcemick25-Feb-05 4:44

Re: Add buttons to a Property Sheet

25-Feb-05 4:44

I've been reseaching Property Sheets for a couple of days now and I'm starting to get the hang of them. I have created a Property Sheet with 5 Property pages; each page contains some controls for displaying and manipulating data.

What I'm wondering is how do I go about adding buttons and a menu to the Property Sheet, not the Property Page? I've read a few things here and other places, but nothing seems to fit (or work) with what I'm working on.

Any help would be appreciated.

PJ Arends25-Feb-05 6:47

Everything is done in your propertysheet's OnCreate() member function.

For a menu, add a CMenu variable (m_Menu) to your property sheet class. In OnCreate call

m_Menu.LoadMenu(IDR_MENU1);
SetMenu(&m_Menu);

For buttons, add CButton members to your property sheet class. In OnCreate call m_Button.Create(...) for each button.

You can handle the commands from the menu and buttons using regular MFC message mapping.
