No, they're not dependencies. We have multiple actual programs which use the same shared DLLs, so the DLLs are mostly standalone projects alltogether.

You think I can trace the leaks when I include the DLLs in question in the workspace of my project?

Yep I do. I thought you were already doing that. Do you know how to make them a dependancy? I'm assuming yes.

I guess just adding them to the workspace will do the trick, no?

If not, then please tell me Smile | :)

Yes. But you have to make sure that the main exe project depends upon these dll's. This is done by: In the File View, right click on the "Workspace", Select "Insert Project into Workspace", when the dialog comes up, select the project to insert (the DLL in question), then check the "Dependency of" and select the main exe. When finished, make sure that you have "Debug" selected as the build and do a "Build All". This will compile the files for the DLL and your exe that uses them. Run the puppy and see what happens.

You should be able to simulate a button on the title bar simply by positioning it with MoveWindow.

Why toolbar is under menu by view ?

Why toolbar is drawn in window created by CreateEx() -
not LoadFrame() like CMainFrame,

shows only CView-like toolbar -
it under flat level menu of window?

And CView size must take toolbar size into account in
client area in OnSize() ?

<br />
		hr =  m_PAlarmWnd-><br />
			CreateEx(<br />
			NULL|WS_EX_CLIENTEDGE      ,//WS_CHILD |WS_BORDER <br />
			NULL,(LPCTSTR)strHeading<br />
			,WS_VISIBLE |WS_CAPTION|WS_POPUP| //|WS_OVERLAPPED <br />
			//|WS_SIZEBOX | WS_MINIMIZEBOX | WS_THICKFRAME <br />
			WS_SYSMENU| WS_THICKFRAME| WS_MINIMIZEBOX| WS_MAXIMIZEBOX <br />
			//|WS_OVERLAPPEDWINDOW<br />
			,0,0,900,600, <br />
			pParent->GetSafeHwnd(),<br />
			pMenu->GetSafeHmenu()//	IDR_MENU1//<br />
			,0);<br />

why also
do not displays tooltips,
but if to do not insert style TBSTYLE_FLAT
tooltip appears ?

Dialog in a thread

Hello!
I'll try to explain my problem as precise as possible.

Imagine I have several charts on the screen that displays some signals. I want to let the user calibrate them when he wants. So, I open a dialog in wich he can enter the data for the calibration of the signal.
Up to here, no problems. But I want the signals to be active in background! So I need this dialog to be in a indepedant thread. But this give me a Debug Assertion Fault.

Here is my code:

DWORD WINAPI CalibrateThreadProc( LPVOID pParam )
{
	CCalibrateDlg* pCalDlg = new CCalibrateDlg;
	pCalDlg->DoModal();

	return 0;
}



void CMonitoringDoc::OnCalibrate() 
{
	// TODO: Add your command handler code here
	DWORD ThreadID;
	HANDLE m_pCalibThread = CreateThread(
					NULL,	//No Security
					0,		//Same Stacksize
					CalibrateThreadProc,	//Thread Proc
					this,	//Adress of my class
					0,		//start at once
					&ThreadID);
}

What is the problem ?? I don't pass any C++ object through the thread (or I don't use it).
Thanks

You haven't said where the ASSERT is occuring, but I assume it is in pCalDlg->DoModal();

I'd suggest forgetting the thread and using a modeless dialog, which will be a lot simpler. If you want to persist with the thread then you need to derive a class from CWinThread. Read up on UI threads vs. Worker threads.

I use modal dialogs in threads in ED (see sig) which appear as modeless dialogs as far as the user is concerned. The various Find dialogs work this way. It is a fair bit of work though to get everything working properly.

Hi,
I want write a SQL to insert records into my table(The table has
a large amounts of fields,more than 100).
The SQL is a CString, but it is too big and exceeds the
maxium length of a CString. Please help me how can I
create a string with any huge length? Code examples would
be more appreciated.Or any other method?

Thanks a lot.

WTF | :WTF:

The maximum theoretical length of a CString is 2 GB. If you have SQL longer than what 2 GB can hold, better redesign your DB.

How about you create a CString for every row in the table instead!

Then you can use CStringArray

Since it's quite difficult to write a 2GB query(!), I guess you are writing something like
CString SQLString (a string longer than 2048 chars);
If this is your code, there is not a problem related to CString, but it is a limit of the compiler: in vc6 a string cannot be longer than 2048 characters.

So, you could simply try
CString SQLString;
SQLString="First part of query smaller than 2048";
SQLString+="Second part of query";
and so on...,

Hi, guys:

I've developed a dll which need several other dll's. It's OK when I "regsvr32 mydll.dll" and it works perfectly. But, the releaseminsize version give me "LoadLibrary(mydll.dll) failed - unspecified error".

What's wrong with the releaseminsize version ? How can I get it working?

TIA
