Debugging I can see that I get the error on the DDX_Radio function that I call in the DoDataExchange of my DialogBar.
The error is a "simple" Debug Assertion Failed!

You should really try to provide all the useful information:
- Code snippet + where the code is crashing
- Exact error message (if there is a message in the assertion, it is probably for a reason, no?)

well... i'll try to explain better the situation...
i have a CDialogBar with this DoDataExchange:
void CMyDlgBar::DoDataExchange(CDataExchange* pDX)
{
CDialogBar::DoDataExchange(pDX);
DDX_Radio(pDX, IDC_RADIO1, miRadio);
}
i create my CDialogBar in my MainFrame and then i call a function for the initialization of my class.
int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if(CFrameWnd::OnCreate(lpCreateStruct) == -1)
return -1;
mMyDlgbar.Create(this,
IDD_DLGBAR,
CBRS_LEFT | CBRS_HIDE_INPLACE,
IDD_DLGBAR);
ShowControlBar(&mMyDlgbar, FALSE, FALSE);
mMyDlgbar.InitDialog( );
return 0;
}
My InitDialog function calls the UpdateData(FALSE) (or UpdateData(TRUE), it's the same).
void CMyDlgBar::InitDialog()
{
UpdateData(FALSE);
}
the UpdateData function calls the DoDataExchange of my class, i get the error on the DDX_Radio function.
No particular message is provided when i get the error.

Hello people!
I know this sounds sick, but...sadly in our project the requirement arose to let the user click on a control "behind" a modal dialog. This control is on the main window of our application which is also the parent of the modal dialog and the requirement says that the user should be able to click around this one control in the main window but he should not be able to use anything else that is not on the modal dialog.
I know i could make the dialog modeless and disable everything on the main window except for this one control but this solution doesn't sound all that "sophisticated" and i am hoping for a better one, not to mention that if i disable everything else on the main window the user will still be able to move it around and resize it while the dialog is up and that is also not acceptable but hacking into the moving-sizing functionality also sounds disgusting. Another problem with this aproach would be that certain things around the main window might change enabled-disabled states while the dialog is up depending on certain events (mostly triggered by changes in hardware) so simply disabling everything and re-enabling them once the dialog is closed is not that obvious as it sounds.
Another thing i can think of is capturing the mouse input to the dialog and checking what is under the mouse when it is clicked and if it is that certain control, post/send the mouse messages to it, this might or might not work and also this causes problems when the user tries to move the dialog itself around or when it clicks on a button in the dialog.
I tried catching the needed mouse messages in CWinApp::ProcessMessageFilter or CWinApp::PreTranslateMessage but these don't seem to get called if the user clicks outside of the dialog.
So, any of you have a better idea how to do this if it is possible at all? Is there maybe a filter method i could overwrite somewhere that filters out clicks outside of the modal dialog?
Thanks in advance.

Why don't you move/copy the control on the modal box?

That idea crossed my mind too but this control is very much integrated into its surroundings not to mention this solution would cause a huge crowd of angry willagers chasing me with pitchforks and torches. Thanks for the idea though.

This shouldn't be a problem: just copy the needed context and functionality.

In the DialogBox() or DialogBoxParam() call set hWndParent to NULL: this creates an 'unowned' dialog, which decouples it somewhat from your main window. Also set EXSTYLE WS_EX_TOPMOST in your dialog resource definition: this will keep the dialog on top of all other windows. You should then be able to click a button on the main window. You will probably also need to disable all the controls on the main window except the one allowed one if the dialog is active.

Thank you for your suggestion but this seems to be the same thing as the first possible solution i described in my post which i don't want to use. Correct me if i am missing something obvious here.

Nothing I can think of, but I still think that the effort required to achieve what you are suggesting is not worth it.

don't know whether i am on the right track.. when you click outside a modal dialog the message it is posting will be 0x118.. with wParam 0xfff8 by handling that you can check for your mouse pointer position and check whether it is the area where the component fall in the parent. You don't have to wait for a click on the button but for the mouse click on that area you can trigger that function.. I think i am clear.

I don't think this is quite true, the messages posted on a mouse click are dependent on where the mouse is positioned: a menu item, button, task bar etc.
This will not provide consistent or reliable results. If this click happens to be on another open window, then that window will be given the focus and receive the message. This is a very unsafe way to handle messages; if you bypass the rules prescribed by Microsoft, then you must be prepared to accept that it may not work as you wish.

I didnt get your exact need but still i think you are looking for something mentioned
below:-
Before i answer i have small doubt regarding the type of applicaiton.
so a question.
Whether your application is SDI application with CEditView or
From assumption
If it is CEditView then override OnChar(UINT nChar, UINT nRepCnt, UINT nFlags) function of CView by choosing WM_CHAR from classwizard.
And simply check the character with nChar value.
if it is "s" then simply load the bitmap corresponding to it, but i think CRichEdit will support Bitmap loading.
If Edit box(CEditCtrl) then
Firstly override the PreTranslateMessage of Dialog and
you can use the below code if only one edit box else
get the position to to get the exact edit box before checking for the message WM_CHAR.
BOOL CYourDlg::PreTranslateMessage(MSG* pMsg)
{
if( WM_CHAR == pMsg->message )
{
AfxMessageBox( "sa" );
}
return CDialog::PreTranslateMessage(pMsg);
}
Величие не Бога может быть недооценена.

Please use the code block button when posting code snippets.
Whenever a COM error happens, the HRESULT return value is quite informative, please report it.
