I use a toolbar within an dialog. This toolbar is resized, whenever the dialog is resized via a call to SetSizes (the height and the width are changed). But sometimes if the dialog windows was inactive for some time, the toolbar gets the wrong size. Looking into the code of CToolBar::SetSizes I found the following:
<br />
if (::IsWindow(m_hWnd))<br />
{<br />
VERIFY(SendMessage(TB_SETBITMAPSIZE, 0, MAKELONG(sizeImage.cx,<br />
sizeImage.cy)));<br />
VERIFY(SendMessage(TB_SETBUTTONSIZE, 0, MAKELONG(sizeButton.cx,<br />
sizeButton.cy)));<br />
Invalidate();
}<br />
else<br />
{<br />
m_sizeButton = sizeButton;<br />
m_sizeImage = sizeImage;<br />
}
I think the problem is that the toolbar is only resized, but the new size isn't stored in the local variables m_sizeButton and m_sizeImage. I can't access them because they are private. It seems that sometimes, the Toolbar is completely redrawn with the sizes stored in m_sizeButton and m_sizeImage. I think this is a bug in CToolbar. It should always set the local variables to the current sizes (no matter if the window exists already or not). How can I get around this bug.
In which method the Toolbar is redrawn with the sizes from m_sizeButton/Image? When is this method called? And the most important question, how can get around this?
I use Visual Studio 2003 with the MFC 7.1. Thanks in advance, Konrad Windszus

I have got a CListCtrl (Report View) in a resizable CDialog. Whenever I resize this dialog, I change the column width via a call to CListCtrl::SetColumnWidth, so that the horizontal scrollbar isn't necessary.
Unfortunately there seem to be a bug in the CListCtrl. Whenever a vertical! scrollbar is showed (because there are more items in the CListCtrl than it can display) and I scroll down and then resize the CListCtrl that the vertical scrollbar disappears, the first row in CListCtrl is empty and not selectable. Seems that the scrolling doesn't work correctly in this specific case.
I use the following code in OnSize of the CListCtrl:
<br />
CRect rect;<br />
GetClientRect(rect);<br />
<br />
SetColumnWidth( 0, rect.right - nLengthWidth );<br />
SetColumnWidth( 1, LVSCW_AUTOSIZE_USEHEADER );<br />
<br />
CListCtrl::OnSize(nType, cx, cy);<br />
Even I can reproduce the bug and found also some postings in the newsgroups from developers which had the same problem, I don't know how to solve the problem.
Please help me. I had the problem with MFC 4, 7, and now even with 7.1
Thanks in advance

I have got a Toolbar in a CDialog. This dialog is a child of CFormView. The tooltips for the toolbar are working, but I would like to display the appropriate text in the CMainFrame's statusbar, too.
So far only the text for the Toolbar ID is shown in the statusbar, when I place the mouse cursor over it. But I would like to have the text regarding to the single buttons of the toolbar.
Any hints in which method the statusbar text messages are handled and how i can display the correct text in the statusbar?
Thanks in advance
Konrad

You should define a string with the same ID as the ID in the toolbar buttons.

I already defined some strings in the stringtable with the same ID as the buttons, but that doesn't work.
The problem is, that the toolbar is not child of the CMainFrame but child of an CDialog, which is child of an CFormView (the main view).

The mainframe handles the diplay of the toolbar/menu text in the function GetMessageString. You should investigate this function and see if you need to override it and provide your own implementation to get what you want working.
Searching for 'GetMessageString'...

Does anyone know if there is code available on the web that shows how to implement a fairly sophisticated street address parser? (street name, number, route, box...)
|
|
|
|
|
Work for the emergency services doing a gazeteer product - what exactly do you mean by parsing an address - surely it's just a string manip. thing.....
If on the other hand, what you need is something to look at an unformatted addr and split it into its constituent elements then will be in a world of hurt.....all it takes is a null locality / area / route or the like, and it all goes screwey!
If still looking for something, then mail me at richardgrimmer@hotmail.com, but please put Address Problem in the subject so I know not to bulk delete with all the other crap.....

hi,
i want to ask the Event handle returned from createevent method is shared among different process or it is secured of being used by different process.the first aurgument i 've supplied to the method is null.
if is not secured , then how can it be made protected of begin used by different process.
thnaks in advance

AFAIK the only way you can share HANDLEs between processes is by DuplicateHandle and starting the other processes as "children" from this "parent" process that created the handle.
This is AFAIK all documented in MSDN and other sources.

Hi all,
I want to find the details of all the clients in my network. How I can do that?? I feel SNMP is having the limitation of enable that service in all the clients. Is there any other option left?? I am a developer in C++. Can any body suggest some API's or Links.
Thanks in advance,
Regards,
Satya Prasad

What "details"? What "clients"? What "my network" (your CIDR/n subnet or "My Network" according to MS)?
To perhaps point you in the right direction:
Whatever information you want any single machine to provide you with, that machine must have a service/server to provide you with that information. Unless you specify what information you want, it's impossible to even give a remotely correct answer by anything but pure coincidence.
|
|
|
|
|
If you want to enumerate your network resources, there are some cool API calls you can make. The example is given in MSDN documentation. You could enumerate from your program all the printers, machines, etc. on the network.

Hi,
Sorry I didn't put my question correctly. I am having a private network. I want to get the Client details like MAC, OS and others. I don't want to use SNMP. In that case how to do this?? Thanks 
Regards,
Satya.

1. In MSDN, the disactive Page not initialize if you not click it, how can I initialize all page when the sheet is shown?
2. When I use the function "UpdateDialogControls" in a CPropertyPage, in Debug mode, it works perfectly, but in release mode, some warning will be shown, and the applications will destory, why?
|
|
|
|
|
about 1:
i don't understand your problem, Isn't all we need
to addpage before creating the propertysheet? Then all the page you add will be shown.
|
|
|
|
|
In MSDN, the Method "AddPage"'s describe, MS told us "AddPage adds the CPropertyPage object to the CPropertySheet object’s list of pages but does not actually create the window for the page. The framework postpones creation of the window for the page until the user selects that page.", so if I don't click the page, the page's member can not be accessed or make a exception. But if I click the page, the "OnInitDialog" will be executed, so I can access the page's member when the sheet destory. so I need initialze the all pages when the sheet be shown, the all pages's "OnInitDialog" will be executed.
|

|
|
During the constructor, modify the m_psp struct of the newly added property page in this way:
this->m_YourPropertyPageDlg.m_psp.dwFlags |= PSP_PREMATURE;
hope this helps.

Thank you !!
please see the picture .
the rigth button's code is here
{
CMainFrame *pMain=(CMainFrame*)AfxGetApp()->m_pMainWnd;
CSuiZhongView *pView=(CSuiZhongView*)pMain->GetActiveView();
CEdit* pE=(CEdit*)m_wndDlgBar.GetDlgItem(m_edit);
CString szO;
pE->GetWindowText(szO);
if(szO!="µ¥Î»Àà±ð")
{
pView->FindData(szO);;
}
}
yes is pass ,can find the data I need.
but ,when I change the item of the tree ,vc only say "yes"
then fail.
why?
Here is the Treeviewclass' code!!!

Yes, it's a nice dot. 2x2 pixels on my screen at this viewing resolution. Black.
the rigth button's code is here
And the other button is... left, or wrong?
I'm sorry for being a pest like this, but without you asking a question, not to mention posting code with no reasonable formatting, containing characters in some asian character set (i.e. looking like a broken gfx driver), how are we supposed to help you with your problem?
<mode=blunt, but honest>
I could also be more direct and say "Do your own debugging". If you can't even debug your own SEGVs I think you've either selected the wrong line of work or the wrong programming language.

Cool! At my current screen resolution 1024x768x16 the dot is only 1x2 pixels! What resolution do you use???  ;)

I guess the problem lies on line:

I don't think, that my sql server is able to process it
