I agree with You.
I will give you a simple help.
For example:
The constructor of CArray is:
CArray<TYPE, TYPE>
Never forgot #include <afxtempl.h>
You can define
CArray<int,int> ptArray;
Or
CArray<MyClass, MyClass> ptArray;
ptArray.Add(20); //Add 20 as element 0
ptArray.Add(15); //Add 15 as element 1 in the array
ptArray.InsertAt(0, 23)); // New element 0
int num = ptArray.GetAt(1); //returns the element 1
int nSize = trArray.GetSize(); //returns the number of elements in the array.
you can append a array to another array
for example.
CArray<int, int> oArray;
oArray.Append(ptArray);
with removeAll you can delete all elements in the array.
ptArray.RemoveAll();
with RemoveAt() you can remove n elements in the array.
RemoveAt(nIndex, num)
ptArray.RemoveAt(1, 2); //remove starting from the element 1, two elements.
You Understand????

Yes I understand. Thanks! It looks alot like a list control. I'll play around with it.
Thanks for all your help!

I take it you've had CArray explained to you sufficiently, I'll only add that it is better to use vector from the STL for a myriad of reasons.

Thanks Christian,
I looked into using stl vector a few weeks back, but it looks to be much more complicated to use.. at least for what I am trying to do. I think I'll stick with the CList in this project but I am defiantly going to study up on both the CArrays and STL Vectors so I can use either in a future project..
Thanks again!

STL *looks* complex at first, but it really isn't. By all means stick with what you know if you need to get something done, but it will definatley be worthwhile to investigate STL when you have time. Plenty of people here to ask if you get stuck.

I'd "second" Christian's advice on STL std::vector (and std::list) - they are well worth the time to learn, are not actually all that complex, and will lead you into a whole range of new coding techniques and possibilities.

Hi
I have a problem :
When I finished my software in Visual C++ (It is about Winsock and ODBC) and it runs very well on my PC, I saw that in others PC that they haven't installed Visual Studio the software doesn't run.
I compilled my software like a static library but it doesn't run too
My question is How I can run my software in other PC then they haven't installed the Visual Studio?.
Thanks

You need to Know what files do you need, for example:
If you are using MFC you need to distribuit the msvcrt.dll and mfc42.dll, if ypu are using odbc also you need to distribuit the odbc librarys, if that pc have not odbc, etc.

Hello All,
I am creating a MFC Extension DLL (not regular DLL) to export MFC classes and checked the Automation option. However, the generated code is not sufficient to function as Automation client.
The DllGetClassObject/DllCanUnloadNow etc codes are not generated. Do I have to manually add this? If yes, what are the other necessary steps to take to conform to the MFC Automation structure? (for instance the regular DLL calls the COleObjectFactory::RegisterAll() in the CWndApp::InitInstance() method. Do I have to do something similar?)
Best regards,
Paul.

Do you know any class that can put a BMP as a background in a window??
I know that CpictureWindow here on CodeProject but I don't handle it! 
Do you know a class that can do that!??

What problems do you have with CPictureWindow
Do you want to tile this bitmap across the window, stretch the bitmap to fit the window or just paint it in the centre?

Which line of code is called before you get the assert?

The are a couple of command line parsers on code project, including

I have a class, it does apsolutely nothing extra ordinary. It wraps a variable of type CArray<class *,class="" *="">, and allowing various other parts of the software access to the contained in this CArray.
See the code below :-
CArray(CQuestion *,CQuestion *) m_caQuestionSet;
However sometimes (approx 1 in 4 times) the destructor code generates an Exception (this is Windows CE so I am using Structured Exception Handling).
See the code below :-
CQuestionSet::~CQuestionSet()
{
__try
{
CQuestionSet::SaveOut();
CQuestionSet::SaveOutAsXML();
}__except(InfoExceptionFilter(GetExceptionInformation()))
{
TRACE0("CQuestionSet::~CQuestionSet(): Exception Occured");
}
}
both SaveOut() and SaveOutAsXML() has their own Exeption Handler, which is never called. Whats generating the damn exception in ~CQuestionSet;

I am creating a DB with ADOX, and it opens fine in Access, I can add records there. If I view the file in my program, opening the recordset like this:
_RecordsetPtr records = NULL;
records.CreateInstance(__uuidof(Recordset));
try
{
records->CursorType = adOpenStatic;
records->CursorLocation = adUseClient;
records->Open("SELECT * FROM FileDatabase",
_variant_t((IDispatch*)m_Connection, true), adOpenKeyset, adLockOptimistic,
adCmdUnknown);
}
catch(...)
{
}
if (records->RecordCount == 0) return S_FALSE;
records->MoveFirst();
It works. I do a do while !records->adoEOF and it reads everything in and displays it fine. I am trying to add records, and I use the exact same code to open then DB, but then I am checking each potential entry to make sure the primary key ( a filepath ) is not duplicated:
for (it = vecFileEntries.begin(); it != vecFileEntries.end(); ++it)
{
if (records->RecordCount != 0)
records->MoveFirst();
CComBSTR bstrPath;
(*it)->get_FilePath(&bstrPath);
char * pStr = new char[bstrPath.Length() + 24];
memset(pStr, 0, bstrPath.Length() + 24);
sprintf(pStr, "[FilePath] = \'%s\'", (char*)(_bstr_t)bstrPath);
try
{
records->Filter = (bstr_t)pStr;
}
catch (...)
{
MessageBox(NULL, "Error", pStr, 0);
}
if (records->adoEOF)
{
and so on - the point is that here before AND after the filter, no matter how many records I have, the recordset->recordcount is always 1, and so nothing is ever added. I tried checking recordcount directly instead of adoEOF, I tried removing the check ( it crashed when trying to add records ). I've been through in Access to make sure the properties of the table are the same, I dunno what else to do.
This is how I create the file:
HRESULT hr = S_OK;
ADOX::_CatalogPtr m_pCatalog = NULL;
ADOX::_TablePtr m_pTable = NULL;
try
{
TESTHR(hr = m_pCatalog.CreateInstance(__uuidof(ADOX::Catalog)));
char * pChar = new char[400];
memset(pChar, 0, 400);
sprintf(pChar, "Provider=Microsoft.Jet.OLEDB.4.0;Jet OLEDB:Engine Type=4;Data Source=%s;", (char*)DatabasePath);
m_pCatalog->Create(pChar);
delete [] pChar;
TESTHR(hr = m_pTable.CreateInstance(__uuidof(ADOX::Table)));
m_pTable->PutName("FileDatabase");
m_pTable->Columns->Append("FileName",ADOX::adVarWChar, 255);
m_pTable->Columns->Append("FilePath",ADOX::adVarWChar,255);
m_pTable->Columns->Append("FileLength",ADOX::adInteger,0);
m_pTable->Columns->Append("TimesDownloaded",ADOX::adInteger,0);
m_pTable->Columns->Append("LastModified",ADOX::adInteger,0);
m_pTable->Columns->Append("Frames",ADOX::adInteger,0);
m_pTable->Columns->Append("Seconds",ADOX::adInteger,0);
m_pTable->Columns->Append("Width",ADOX::adInteger,0);
m_pTable->Columns->Append("Height",ADOX::adInteger,0);
m_pCatalog->Tables->Append(
_variant_t((IDispatch *)m_pTable));
}
catch(_com_error &e)
{
_bstr_t bstrSource(e.Source());
_bstr_t bstrDescription(e.Description());
MessageBox(NULL, bstrDescription, bstrSource, 0);
return E_FAIL;
}
catch (...)
{
MessageBox(NULL, "General Error Creating Database", "Error", 0);
return E_FAIL;
}
return S_OK;
Any help appreciated, as always.

Few points to consider
1. using the recordcount, will not always give you the correct count of records, this is only an indicator (watermark) of how many records exist.
I Suggest you use a SELECT COUNT(*) FROM [TABLE] query to get the correct record count.
2. When you use Column->Append
the Size of the adInterger is not 0, but sizeof(long)
I am not sure if this will cure your problem, but it may help

Hello,
Does anyone know of a utility or sample code that creates a file of custom size? I would like to do some testing with my application with reduced disk space and would like to be able to create an arbitrary file with a defined filesize. For example, if I want to test what happens when I save a file to a floppy that has a 1MB file already on it. The 1MB file would be the file that I created to reduce disk space.
Any ideas?
Thanks in advance!
Derek
