Sorry I dont understand what you are saying.
I declare an array of pointers to the dialogs:-
CIDUDlg g_pIDU[4]; Then in the OnInitDialog()
of the main dialog I set the first pointer:-
g_pIDU[0] = this;
So how and where do I create the second dialog and then set the pointer:-
g_pIDU[1] = ???;

This is speculation - something to try if you get desperate 
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 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>
</font> dlg.DoModal(); <font color=#008000>
</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>
}
<font color=#008000>
</font> <font color=#0000FF>return </font>TRUE;
}
hope you understand better now

I am trying to add a "C" file to a C++ program. I get
"fatal error C1010: unexpected end of file while looking for precompiled header directive"
and it will not compile. How do I get around this problem. Conversion to C++ will be very difficult to complete.

disable precompiled headers with the VC++ settings > Debug, don't use precompiled Headers.
this error has no relationship with convert C to C++.

You can disable precompiled headers for SPECIFIC source files wihtin your project, leaving the C++ files to continue to use the precompiled headers  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 may have posted this earlier... Anyway... this was written in Borland Builder. This code was written in c++ language. I'm trying to clarify on what's going on. I"m trying to send the message text to the printer. This code did work in Win98. BTW, is there any Borland c++ anywhere in the 'net? The Bynamic-c website is no longer there.

i have a win32 app - it runs at background, no any user interface such as dialogs or windows.
the size of the app is very important, but it is almost up to 60K, i need to make it much smaller - do you have comments for me?
thx
includeh10

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?

tree-view has a sorting function, it is good enough for your case.

HTREEITEM htiParent = m_pTreeCtrl->InsertItem (strTreeItems[0]);
HTREEITEM htiChild; // child item
htiChild = m_pTreeCtrl->InsertItem (strTreeItems[1], 1, 1, htiParent, TVI_LAST);
m_pTreeCtrl->SetItemState (htiChild, TVIS_BOLD, TVIS_BOLD);
// add the children of the parent item
for (int i = 1; i < 4; i++) {
m_pTreeCtrl->InsertItem (strTreeItems[2], 2, 3, htiChild, TVI_LAST);
}
the code works as you wish, strTreeItems[x] is the Itemtext, that's looks like
+strTreeItems[0]
++strTreeItems[1]
+++strTreeItems[2]
+++strTreeItems[2]
+++strTreeItems[2]
+++strTreeItems[2]
you can do it yourself i think~~~~~~~~~enjoy
cheer up!!!!!

I want to invoke ON_BN_CLICKED event of a button named bn_test manually from my code. Is there any possibility to invoke in this way?
|
|
|
|
|
if the button has an unique ID, i think you can add it as code auto generated by MFC.
includeh10
|
|
|
|
|
Why not just call the handler function directly?
BEGIN_MESSAGE_MAP(COptionsGeneralPage, CPropertyPage)
ON_BN_CLICKED(IDC_XB_ODBC_ENABLED, OnXbOdbcEnabled)
END_MESSAGE_MAP()
...
OnXbOdbcEnabled();
