Hi,
I am getting the following error while building the code in Debug code:
error PRJ0019: A tool returned an error code from "Performing Custom Build Step
Please help regarding the following error.

from MSDN:
An error level was nonzero for a custom build step or build event.
It seems that your custom build step failed. Plz check the steps written in it.

MC: -u switch must be used with Unicode message file!
May be your project settings are ANSI, and you are using switch -u which is for unicode files. Use -a in place of -u.
Or paste the "Custom build step" steps. Also tell about your project settings, ANSI or UNICODE ?

How clear do you want it? The Message Compiler (MC) is needing the -u switch. See here.

The class for showing the dialog is CFileDialog .
You can use the following sample code -
char szFilters [] = "Text Files (*.text)|*.txt|";
CFileDialog FileDialog (TRUE, "txt", "", OFN_FILEMUSTEXIST, szFilters, this);
CString FileName;
if (FileDialog.DoModal () == IDOK)
{
FileName = FileDialog.GetPathName ();
}

Hi,
I have list control whose property is set to
"List1",IDC_CmdResp,"SysListView32",LVS_REPORT |
WS_BORDER | WS_TABSTOP,293,37,146,214,
WS_EX_DLGMODALFRAME | WS_EX_CLIENTEDGE | WS_EX_RIGHT |
WS_EX_STATICEDGE
Am displaying the data read from the serial port in the list control but there is lot of filckering.Below is the code to display the data in list control.Is there any thing am missing in the code.Why there is flickering?More flickering starts when i start deleting the data.If i don't delete i get assert error that maybe due to memory overflow of the list control.Plz help me out.
void CNgpptDialog::ReadSerialData(CString sIn)
{
CString pressure_data;
ptrCmdResp->SetRedraw(false);
pressure_data=sIn;
int counter = ptrCmdResp->GetItemCount();
ptrCmdResp->InsertItem(counter, "");// to insert a row
ptrCmdResp->SetItemText(counter, 0, pressure_data);// column0
ptrCmdResp->EnsureVisible(counter, FALSE); // Scrolls downwords.
if(counter > 150)// I start deleting first data when the number of items in the list control is > 150
{
ptrCmdResp->DeleteItem(0);
}
ptrCmdResp->SetRedraw(true);
int nIndex = ptrCmdResp->GetItemCount();
ptrCmdResp->RedrawItems(nIndex,nIndex);
}
}
Thanks in advance

With one post is enough... at least you could change your text and explain yourself in another way. Maybe is not clear what you mind (i.e. I don't know the word flickering)

K Got it.
The actual issue is
When i place the data in List Ctrl the data is unsteady.As am placing data continuously(120 samples/ sec)and i have run the s/w for many days continuously, i need to delete the data in List Ctrl otherwise buffer of the List Ctrl will overflow.After displaying 150 samples in Ctrllist am starting to delete at this moment data is unsteady.
Thanks

Well, I reset tmy ListCttrlView everytime the OnDraw is called to empty all datas and then I write the newest values.
void CMyTabView::OnDraw(CDC* pDC)
{ if (m_bJustOpened)
InitializeView ();
if (m_bListRedraw)
DrawViewElements ();
return;
}
In initialize views I configure the number of columns (may be variable from 8 up to 32). Write the name of columns and so on...
By DrawViewElements (); my FIRST line is: m_clcRuleList.DeleteAllItems ();
and then I write them down another time.
And with that you can call the OnDraw easily with an pDoc->UpdateAllViews (NULL); in a Timer with the interval you desire

Comment out these two statements and see what happens.

There is no difference

So if all you are ever going to show is 150 items, why not store those in a fast container of some sort, and populate the list control from that container instead. Doing I/O on such a container would be way faster than the same I/O on a UI control. Make sense?

Hi all,
I am having an issue converting this
string pRetVal;
if ((PROP_TYPE_MASK & PropertyID) != PT_STRING8)
{
return 0;
}
redmap::mapi::FoundProperty prop = m_Message->FindProperty(PropertyID);
if (prop.second)
{
pRetVal = _bstr_t(prop.first.lpszW);
return (pRetVal);
}
else
{
pRetVal = ("");
return (pRetVal);
}
There is something wrong in how I am converting prop.first.lpszW because the out put I am getting is instead of "text here" I am getting "????????"
originally this is a COM made snippet
BSTR* pRetVal;
if ((PROP_TYPE_MASK & PropertyID) != PT_STRING8)
{
Error("Invalid property type");
return E_FAIL;
}
redmap::mapi::FoundProperty prop = m_Message->FindProperty(PropertyID);
if (prop.second)
{
ATL::CComBSTR bstr (prop.first.lpszA);
return bstr.CopyTo(pRetVal);
}
else
{
ATL::CComBSTR bstr (L"");
return bstr.CopyTo(pRetVal);
}
Now what is wrong with my conversion? What is the right thing to do?
Thank you all,
Jj

I got it know I didn't notice I was using lpszW instead of lpszA.

Hi... this is a bit philosophical ... I noticed a class attributed getting corrupted *on return* of a function... BUT when I step INTO the function, no memory corruption even when debugger pointing at *last* line (return statement) of the function. It wasn't until [the moment] debugger stepped *out* of the function when the class attributed is corrupted.
I'm looking for general idea/approach to such problem:
<br />
class CSomeClass { <br />
void MethodA(...) <br />
{ <br />
... <br />
MethodA1(...);<br />
MethodA2(...); <br />
MethodA3(...); << Boom!! m_attrib corrupted the moment MethodA3 returned debugger still pointing at this line *after*MethodA3 executed/return (I know from Watch Window) <br />
MethodA4(...); <br />
MethodA5(...); <br />
... <br />
} <br />
<br />
int MethodA3(...) <br />
{ <br />
... code ... <br />
return id; << m_attrib still okay but this is last statement of the method! <br />
} <br />
<br />
static SomeAttrib m_attrib; <br />
<br />
};
Note that the attribute "m_attrib" is static. And I don't think this section of the code is multi-threadedn (i.e. I don't see any AfxBeginThread or anything similar within the process boundary).
I guess the question is, what happenned between last statement (return id) within MethodA3, and immediately after debugger step out of MethodA3.
Thanks!

I would hazard a guess that the problem you are encounterring isnt happening where you think it is, and that this is in fact a classic stack corruption problem. Examine carefully the code in MethodA3() for buffer overrun conditions.
FYI, Both of the links given in REF: are broken.

The corrupted variable was allocated on heap..
thanks though...

Hi all,
Do need a favour here. I would like to monitor an application and kill it if it is hang and regenerate it. However, not able to find relevant code.
I'm able to get the kernel and user time by "getprocesstime". But not able to monitor the CPU usage (not able to get idle time) to kill the hang program.Understand that some programmer use "GetSystemTimes" function. But it does not work in my PC.
Any suggestion or free code to share? Thanks a lot!

There are lots of ways for a program to hang. For instance, I've had just the user interface fail and the program keep running in the background. If you control the code for this program, you could have it periodically signal your monitor program that it's still working. If not, your problem is a lot more dificult.

I see. Based on my understanding, the hang program will reflect very high CPU usage (program in a loop) or usertime and kerneltime unchange (deadlock). Is it possible to trace the particular application's CPU usage? Thanks a lot!

one idea: use Sysinternals' pslist -
(1) have another periodically run pslist<br />
(2) pipe the output the a flat file, <br />
(3) then your *other* application to parse the file for CPU usage<br />
(4) If ProcessA.CPU>30 Then killtask<br />
<br />

many of myserver application are so cpu savvy , it runs on 30-40% i.e. when acquring data from hardware at 20hz( i.e. 20 record per second). that will help ful atleast in my case!
