I may have had a similar problem back several months ago. I have a modeless PropertySheet (a modeless tabbed dialog window) separate from my main Doc-View window.

I created my modeless PropertySheet window:

<br />
// Modeless property sheet - with parent window as such and call to SetWindowPos() allows for property sheet to be on top<br />
m_pSettings->Create(this, WS_SYSMENU | WS_MINIMIZEBOX | WS_POPUP | WS_CAPTION | DS_MODALFRAME | DS_CONTEXTHELP, WS_EX_DLGMODALFRAME);<br />
m_pSettings->SetWindowPos(this,0,0,0,0,SWP_NOMOVE | SWP_NOSIZE);<br />

I do recall that there was something special to this (modeless property sheet) and the peeps here helped me out!

Now i need to pop the values from that queue using thread in MFC application.

Nice to know. And what is the question?

Hi,

i am using MFC application in this application i need to display the received messages from the server (may be a chance for receiving more than one messages at a time) i need to display the received and send messages in the Listbox.
i tried it in normal way, but the UI getting freezed after some time. I can able to log that message. So i tried it in some other way, like using queue
the received messages are added in the queue and at thet time timer is running and one thread will pop the pushed messages in to the ListBox.

Using thread how can i get the pushed value?

Thanks,
Ratheesh.

You should add the messages to the queue using a worker thread, then notify it to the GUI thread (using, for instance PostMessage). The GUI thread eventually pops messages from the queue and displays them. of course you've to lock in same way queue access.

it's probably not safe AS-IS. (stl is not by design thread-safe)

I suggest you implement a simple synchronization mechanism (see Thread Synchronization for Beginners[^] )

Read this article very carefully:
http://www.flounder.com/debug_release.htm[^]

It lists many common errors that show up in Release rather than Debug mode, and also how to add symobols so you can work out where things are actually crashing.

As for "many different locations", then try and get just one location at a time by being very consistent in how you get to the crash.

Good luck,

Iain.

Use Process Dumper tool to get the dump file and analyze it.

You need to google first, if you have "It's urgent please" mentioned in your question.

Create a crash dump and send it. Will try and analyze it.

The name of the module and the offset of the exception will be in the users Application Log of the event viewer. Although a crash dump is certainly useful there is no reason to create one.

How to view and manage event logs in Event Viewer in Windows XP[^]

You can use WinDbg to find the corresponding code if you have saved your symbols. It is very important that you use the same symbols at the time of the Release build otherwise you will not find the correct crash location.

How to bind a LPCTSTR property to a EditBox in property page? [modified]

Hi guys

I have a LPCTSTR property in an activex control I'm designing. (I can't change the property to CString or something else unfortunately)

How do I exchange this property with a EditBox control in the property box? I can't just use a CString, even though DDP_Text function asks for a CString type variable. .

m_CaptionText is CString type *value* variable, set for the EditBox control (IDC_CAPTIONTEXT). CaptionText is the property name.

DDP_Text(pDX, IDC_CAPTIONTEXT, m_CaptionText, _T("CaptionText"));
DDX_Text(pDX, IDC_CAPTIONTEXT, m_CaptionText);

Any help would be highly appreciated.

Cheers

Hi,
im using the below code to increase the column width of each item of HeaderCtrl ...
the below code works fine when the font in headerCtrl and ListCtrl is normal(ie font size 10) suppose if increase the font size in ListCtrl and HeaderCtrl the ColumnWidth is not calculated according the Text width..ie the text in the item of headerCtrl is getting ellipsed..

CHeaderCtrl* pHeaderCtrl = GetHeaderCtrl();
SetRedraw(FALSE);
int nColumnCount = pHeaderCtrl->GetItemCount();

for(int i = 0; i < nColumnCount; i++)
{
SetColumnWidth(i, LVSCW_AUTOSIZE);
int nColumnWidth = GetColumnWidth(i);

SetColumnWidth(i, LVSCW_AUTOSIZE_USEHEADER);
int nHeaderWidth = GetColumnWidth(i);

SetColumnWidth(i, max(nColumnWidth, nHeaderWidth));
}
SetRedraw(TRUE);

In the above code im planning to set the columnwidth of each item in the header Ctrl based on the max width among the text of item in ListCtrl and the text of item in HeaderCtrl...but when the font is increased it"s not calculated properly..
Please try to help..

Have you tried using CDC::GetTextExtent[^] to calculate the string width?
