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

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 ,
NULL,(LPCTSTR)strHeading<br />
,WS_VISIBLE |WS_CAPTION|WS_POPUP|
WS_SYSMENU| WS_THICKFRAME| WS_MINIMIZEBOX| WS_MAXIMIZEBOX <br />
,0,0,900,600, <br />
pParent->GetSafeHwnd(),<br />
pMenu->GetSafeHmenu()
,0);<br />

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

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()
{
DWORD ThreadID;
HANDLE m_pCalibThread = CreateThread(
NULL,
0,
CalibrateThreadProc,
this,
0,
&ThreadID);
}
What is the problem ?? I don't pass any C++ object through the thread (or I don't use it).
Thanks

Sorry, I never think about modeless dialogs 
|

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.

Thats a good advice indeed

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

Is this a "debug" version?

Does this happen with all "release" versions?

Dear All,
I am developing an application in MFC VC++ Version 6.0 for Windows 2000.
I need to restore all the files from my recycle bin. Is there any API provided for restoring Recyclebin data ?
Or any alternative way out to restore the files present in Recycle bin ?
Please send your useful suggestions.
Feel free to ask any further queries in this regards,
Thanks

hi Dominik
Thanks a lot for replying. I have seen this code, but i am encountering two problems:
1)The program is throwing following error:
error: afximpl.h doesnot exist no such file
2) I am not able to understand out how it is restoring the file(ie. which API he is using or what method is being used)
....
Once the program is run then i can debug and make it out how the program is restoring the file.
Can you help me out ?
Thanks

1) See here.
2) It is cleverly using the menu from Windows' Recycle Bin. When you right-click on a file in the Recycle Bin, notice the context menu that appears. Step through the CRecycleBinDlg::ExecCommand() function to see how a file is "undeleted."
Line 635 gets a PIDL to the Recycle Bin folder. Then line 782 gets the context menu of this PIDL. The loop at line 809 searches for the verb (e.g., undelete). Once found, line 858 executes that verb.

This must be a silly problem
I add a new .c or .cpp file to my project with its own .h which it includes:
logmsg.c:
...
#include "logmsg.h"
...
I get:
logmsg.cpp(236) : fatal error C1010: unexpected end of file while looking for precompiled header directive
???

|
|
|
You must either add
#include "stdafx.h"
BEFORE your include, or change the cpp file "Settings" -> "Precompiled Headers" to "Not using precompiled headers".
Cheers,
Andy

Hi...
i am doing a project which makes use of C to create a structure of let's say
struct Data
{
int age;
char gender;
};
when in C, i use sizeof(Data) to pass the value to Visual Basic to write and update the structure, it gives error and after debugging, it bounds to the sizeof() problem as in C++, this sizeof(Data) returns 8 and not 5 while in VB, it gets 5.
Anyone has a solution. i read up the help file and it says cos of trailing and padding. if i change to this
struct Data1
{
char gender;
};
the sizeof(Data) returns me 1.

The Intel processors are most efficient when accessing data that is located at memory addresses that are a multiple of eight (I think). This is common with many microprocessors.
Visual C++ defaults to locating structure members on 8-byte address boundaries. Each data element of a structure (or class) will be located at next memory address that is a multiple of 8. This can be changed in the project settings under C/C++, Code Generation.
You can also get fine grained control using #pragma directives in your code. This might be a better approach since you could pack your structures passed to VB on 1-byte boundaries and leave all the internal stuff at the default of 8 which is much more efficient.
Here is a sample:
<br />
#pragma pack(push, test)<br />
#pragma pack(1)<br />
struct Five<br />
{<br />
int i;<br />
char c;<br />
};<br />
#pragma pack(pop, test)<br />
<br />
struct Eight<br />
{<br />
int i;<br />
char c;<br />
};<br />
<br />
int main(int argc, char* argv[])<br />
{<br />
Five five;<br />
Eight eight;<br />
cout << sizeof(five) << endl;<br />
cout << sizeof(eight) << endl;<br />
<br />
return 0;<br />
}<br />
Hope that helps.
Brad
