Can we search SQL with not empty string & COleDateTime format?

Hi,

I am using VC6.0++ with DAO & MS Access97! So far I use SQL successfully ... well except 2 thing:

*) With this: strSQL.Format ("SELECT * FROM Sample WHERE Title != 'Date'"); I can search the whole Sample table at column "Title" for string "Date"!

1) Let say to do the same, how can I search ... but at any cell has some thing (not empty string, or not empty field)?

2) In the table there is a column with define as COleDateTime, how can I search the same above technique for a equivalent COleDateTime day:
ie: Search for cell has "12/31/2001" in the column "Date"

I appreciate any help help here

Many thanks,

Anh

1) I think that SELECT * FROM Sample WHERE title <> '' AND title IS NOT NULL (I'm not sure if title IS NOT NULL is necessary).

2) SELECT * FROM Sample WHERE Date = '2001-31-12' should do the trick. Beware if the time is included you may have to issue SELECT * FROM Sample WHERE Date >= '2001-31-12' AND Date < '2001-31-12'.

Try those.

It is a lovely language, but it takes a very long time to say anything in it, because we do not say anything in it, unless it is worth taking a very long time to say, and to listen to.

Hi Michel,

Thank you very much for request #1, it works beautifully! However, the suggestion for #2, I tried and failed! Did you try it successfully, or might be I missing some thing?

Many thanks,

Thanh

I don't know MS Acces at all, but I know that for the SQL server to understand your date format, you must know the locale it uses.

For instance, in en-US (0x409 or 1033), '12/31/2001' (try that), in fr-CA (0xC0C or 3084), '31/12/2001', etc...

Somebody once suggested the format I put in #2 to be locale-independant, but it doesn't seem to work in Access. Try the '12/31/2001' and see what happens.

Apparently, during installation, you have to give the common directory a different name so it is not the same as the VC6 one but I accidentally did this and have experienced no problems so far.

Must admit since getting VS.NET, 90% of my time is spent on VC6. It's not that much better to warrant the change at the moment unless you specifically need the .NET features.

in general, you can't use non-static member functions via a function pointer.

it works fine, tho, if you rewrite the code like so:

class MyClass
{
   typedef void (* MyClassMethodPtr)();

   MyClass()
   {
      m_pMethod = voidMethod; //OK
      m_pMethod(); //Error ('error C2064: term does not evaluate to a function') 
   }

   MyClassMethodPtr m_pMethod;

   static void voidMethod()
   {
      //Do do do, boo boo boo...
   }
};

-c

As always, it's bread and circuses. And while bread is down right now, circuses are way up.

The questioner was asking about a member function pointer.
You can not use a static member function with a member function pointer.

You can however, use a function pointer with a static member function.

Function pointers and member function pointers are two different things, and you can't mix them.

Re: Pointer to class memeber func

Axter18-Sep-02 18:07

(m_Obj.*m_Func)()

Try the following:
MyClass()
{
m_pMethod = voidMethod; //OK
(*m_pMethod)();
}

To use function pointers you have to use some funcky looking syntax.
If you're calling the function from inside your class, just prefix the pointer with an asterick, and wrap perantesise around it:
(*MyFunPtr_Array)();

If you're doing it out side of the class, you would use the following syntax:
(MyClassVar.*m_Func)();

I tested the proposed solution I gave you on VC++, and for some reason it doesn't like the syntax without the class prefix.
If you're using VC++, try the following instead:

class MyClass
{
public:
typedef void (MyClass::* MyClassMethodPtr)();
MyClassMethodPtr m_pMethod;
MyClass()
{
m_pMethod = voidMethod; //OK
((*this).*m_pMethod)();
}

void voidMethod()
{
//Do do do, boo boo boo...
printf("Hello World");
}
};

Hi,

I have an array like this :

char sArray[4][5];

I want to declare this array with new or malloc like this :

char** sArray=NULL;<br />
sArray = new char[20];<br />
or sArray = (char*)malloc(20);

Can anybody help me to write correct declaration

Thanks in advance

there is no simple way to do it in C++.

you will have to do something like this:

// alloc an array of arrays
int ** array = new int* [sizex];
for (int i = 0; i < sizex; ++i)
    array[i] = new int[sizez];

Icons with shortcut layers

18-Sep-02 11:55

Hi,
I've made a bad choice in implementing the icon retrieving code in my code. But's hardcoded now and would be toough and bug producing to make any really major corrections now.

So anyway, the question: I need to get the icon of some file (SHGetFileInfo), but with shortcut overlay (or shared overlay, but this is not neccessary), for both 16x16 and 32x32 icons. In other words, a image list that would contain both "shortcuted" and standard icons.

Thanks in advance

Hi All,

I've been having weird heap breakpoints show up in an app that is using the winsock 2 library, and have heard that this may be related to the version of the C runtime libraries I am linking with. Anybody know which version is the corrcet one to use with the winsock libraries? Multithreaded, Single Threaded, Multithreaded .dll?

Thanks

Passing strings from VC to a VB COM dll

ns18-Sep-02 11:11

18-Sep-02 11:11

My VB function signature is:

Public Function MakeDB(txtFilename As String, dataBaseName As String)

I will pass these two parameters from VC as:

CString dbName, myFile;

     edit1.GetWindowText(dbName);

     edit2.GetWindowText(myFile);

     ptr->MakeDB(myFile, dbName)

What I need to know is can I do this or do CStrings and VB strings differ. if so, how to pass these strings to the VB dll?

Thanks,
ns
