How to set the TAB ORDER of a control in runtime manually?

The tab order is simply the Z-order of the windows, so to change it use SetWindowPos() as David suggested.

Hi everyone,

I have a problem with hiding the vertical and horizontal scroll bars of the CHtmlView in a CFrameWnd or CDialog.

How to do it?

I did try with this code in CMyHtmlView::PeeCreateWindow function

cs.dwExStyle &= ~WS_EX_CLIENTEDGE;
cs.dwExStyle &= ~WS_EX_RIGHTSCROLLBAR;
cs.style &= ~WS_BORDER;
cs.style &= ~WS_VSCROLL;
return CHtmlView::PreCreateWindow(cs);

but it does not work!

General Another Main Dialog

sweep12315-Dec-04 6:22

15-Dec-04 6:22

I have a MFC Dialog application, but now I would like to create and display an identical dialog, but with different initialisation when its created.

I thought I could use pointers to share/modife data between the displays I think thats OK.

But if I use the following to create the new dialog (in at the bottom of the dialogs OnInitDialog routine):-

g_pIDU[0] = this; // Main dialog pointer 
// Now create the 2nd dialog 
g_pIDU[1] = new CIDU_Dlg(this); 
g_pIDU[1]->Create(CIDU_Dlg::IDD, GetDesktopWindow()); 
// g_pIDU[1]->InitNextDlg (q); Not a member ??? 
g_pIDU[1]->ShowWindow(SW_SHOW);

I am in a loop as never reach ShowWindow as go back into the OnInitDialog routine (which is the Main dialog initialisation).
Also problem with the InitNextDlg hence it commented out!

I dont want to add another dialog (and all the code/resources etc) to my solution as a copy of the main dialog is what I want, but is that the only way?

Any suggestions please.

where you call your dialog, you create a CmyDialog (for example) object before the dialog is displayed (DoModal() or Create()).
You could make a specific constructor that receive the specific datas to initialize the dialog with. you should also have data members to store the constructor parameters, because you cannot do what you do in OnInitDialog() in the constructor (The dialog don't exist yet). Then, OnInitDialog() will be able to read the data members and create the dialog consequently.

Sorry I dont understand what you are saying.

I declare an array of pointers to the dialogs:-

CIDUDlg g_pIDU[4];   // Ponters to the dialogs

Then in the OnInitDialog()
of the main dialog I set the first pointer:-

g_pIDU[0] = this; // Main dialog pointer

So how and where do I create the second dialog and then set the pointer:-

g_pIDU[1] = ???; // Second dialog pointer

This is speculation - something to try if you get desperate Unsure | :~

I think the problem here MIGHT be that you can not get the Create to work from within the OnInitDialog of the first dialog. Sometimes Windows has limitations of what functions are permitted while others are executing. So... You can post your FIRST dialog a special message to create the secondary dialogs. When the first dialog processes the message, it will no longer be within the OnInitDialog handler, and the other dialogs might create just fine.

Otherwise, I can't see anything inherently wrong with what you are doing, given that you can create child controls within an OnInitDialog call, so it might have something specifically to do with Createing the other dialogs. Or else thee is more to the problem not revealed by your code snippets.

ok, let's say the datas to pass to the dialog are a bool, a CString, and int.
then, you create a specific constructor :

CmyDialog::CmyDialog (<font color=#0000FF>bool </font>bFlag, CString strTitle, <font color=#0000FF>int </font>iSize) 
            : CDialog(CmyDialog::IDD),
            m_bFlag(bFlag),
            m_strTitle(strTitle),
            m_iSize(iSize) {
}

of course, you had previously added the correct members to your class :

<font color=#0000FF>class </font>CmyDialog : <font color=#0000FF>public </font>CDialog {
    <font color=#008000>//...</font>
<font color=#0000FF>protected</font>:
    <font color=#0000FF>bool     </font>m_bFlag;
    CString  m_strTitle;
    <font color=#0000FF>int      </font>m_iSize;
<font color=#008000>//.....
</font>};

then, you can call you function, let's say, when "Open" Button is clicked on the first dialog :

<font color=#0000FF>void </font>CDialog1::OnSClickOpenBtn() {
    <font color=#0000FF>bool </font>b = 0;
    CString str = <font color=#808080>"This is the title of my dialog"</font>;
    <font color=#0000FF>int </font>iSz = 5;
 
    CmyDialog dlg(b, str, iSz);   <font color=#008000>// Implicit call of the constructor
</font>    dlg.DoModal();                <font color=#008000>// Assuming that your dialog is modal
</font>}

the last thing you have to implement in you code is the following :

BOOL CmyDialog::OnInitDialog() {
    <font color=#0000FF>this</font>->SetWindowText(m_strTitle);
    <font color=#0000FF>if </font>(m_bFlag) {
        <font color=#008000>// do some action if the flag is set...</font>
    }
    <font color=#008000>//...
</font>    <font color=#0000FF>return </font>TRUE;
}

hope you understand better now Wink | ;)

You can disable precompiled headers for SPECIFIC source files wihtin your project, leaving the C++ files to continue to use the precompiled headers Big Grin | :-D

They don't have to be disabled for the entire project just because you added one o rmore C files to an otherwise perfect C++ project.
Just expand the project tree so that youc an see the source files, right click on the C source files, and adjust the precompiled header settings for that specific file.

Hi!
I want to add manage extension to my exiting c++ MFC application.
and I found the following link but I couldn't find Compile As Manage property at all.
I chose YES for Use Manage Extension in General property of Configure Properties Folder.
How can add manage extension to my exiting c++ dialog based application so I can use System, System::Text, and other System properties?
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vcmex/html/vcconaddingmctoexistingapplication.asp[^]

Right now.. even I add

 <br />
using namespace System;<br />
using namespace System::Text;<br />
<br />
...<br />
...<br />
Text t;<br />

and the error is Text is not a namespace. I dont 'know why.

Thank you.

i have a win32 app - it runs at background, no any user interface such as dialogs or windows.

are you sure because I have an application with a lot of dialogs (4) and also a large code and it only has 112 KB (114.688 bytes). Are you sure you compiled it in release mode ?
The thing is that there is a program (i don't kn ow its name right now) that makes your exe's 200% smaller.
Good luck

Hi,

I have a problem with sorting duplicate items in a treeview.

I retrive some info from a database and the resultset look something like this :

Date....|City.....|Code
---------------------------
20041012|London...|123
20041012|London...|456
20041012|New York.|763
20041013|Boston...|236
20041013|London...|983
20041012|Oslo.....|923

And I want the treeview to look like this :

+20041012
...+London
......+123
......+456
...+New York
......+763
...+Oslo
......+923
+20041013
...+Boston
......+236
...+London
......+983

How can i put the correct nodes in the correct level and do this in a easy way?
