Well I am doing it. Actually I am deriving a class from CFileDialog but I simply cant catch the WM_CTLCOLOR or WM_CTLCOLOR_REFLECT message whereas when I derive the class from CDialog then I am able to handle the message WM_CTLCOLOR or WM_CTLCOLOR_REFLECT. any help on it.
Regards

i don't know where is that poor dick who vote down anonymously, but 2 things for you, sucker :
1- that was a joke !! can't you see the icon ?
2- the original question wasn't that clear to give a much precise answer ! moreover, people asking that way (I WANT, I WANT) don't generally get much pertinent responses...
now, give me a 1 if you cannot say your name b*tch

Hello, everyone!
I want to develop a network printer monitor, which will run on a network printer server. It should trap every print job sent to it, then send notification about authorization to the client PC which sent this job, and receive and check password messsage, then determine to continue print job or deny it. At last it logs the print job in a local access db.
Perhaps, I should develop a client app which gets authorization information as soon as user start a print job, attaches them to the print job, and sends to network printer.
Any ideas about how to do? Thanks in advance.

Hello.,
I developed an application which stores some data.
Next I create a setup file .
The SetUp file (If I installed in my Machine) works fine in my System, But It can not works fine in other machines.
=>Because I hard coded the DSN name as 'MyDSNName'
and Database Table as 'MyDataBase'
--
I wrote code like this.-=-->
-------------
CString sql,sDate;
CString sDriver = "MICROSOFT ACCESS DRIVER (*.mdb)";
CString sDsn;
CString sFile = "c:\\mydatabase.mdb";
CDatabase db;
sDsn.Format("ODBC;DRIVER={%s};DSN='MyDsnName';DBQ=%s",sDriver,sFile);
db.Open(NULL,false,false,sDsn);
CRecordset recset( &db);
------------
>>I want flexible code ,which works fine for all machines.,

no need for dsn here
specify the path of the database where you are going to install the program
and it will work fine , may be you can specify the path where your exe file is there

|

As I told you yesterday you have to look this article[^]
There you'd fine that you can connect to the DB without using a DSN name:
<br />
strConnection = _T("Driver={Microsoft Access Driver (*.mdb)};"<br />
"Dbq=c:\\DatabasePath\\dbaccess.mdb;Uid=; Pwd=;");<br />

In my application .,
I am hard coded i.e., I created DSN,Database name and Table name as 'MyDSNName','MyDBName' and 'MyTable' respectively.
If I build a SetUp file for this appli., This application works only in my System .But it is not worked in other system.
So I want Flexible code ,which generates the default Databse and Table to the end user.,
(Then It will works in all Machines)
I hardcoded the code like this.,
--------------------->
CString sql,sDate;
CString sDriver = "MICROSOFT ACCESS DRIVER (*.mdb)";
CString sDsn;
CString sFile = "c:\\mydabase.mdb";
CDatabase db;
sDsn.Format("ODBC;DRIVER={%s};DSN='MyDsnName';DBQ=%s",sDriver,sFile);
db.Open(NULL,false,false,sDsn);
CRecordset recset( &db);

define one assignment operator, will be similar to copy constructor. it get called at line t3=s1+s3
|
|
|
|

You haven't overloaded the = operator, needed for the second version. This is a simple implementation:
string operator=(const string &s)<br />
{<br />
delete p;<br />
p = new char[strlen(s.p) + 1];<br />
strcpy(p, s.p);<br />
return *this;<br />
}
I also recommend to rename your class to myString or something like that.

prefer string& operator=(const string& s) as operator = to allow the user to cascading the calls...

I have problem opening the class wizard, as it will show an error message. After clicking ok, i wont be able to add function, variable etc. from the class wizard.
error msg:
Parsing error: Expected "="
Input Line: "if (m_hCloas == INVALID HANDLE VALUE)"
Anyone knows what has gone wrong?
|
|
|
|

I think you have deleted the script generated by the application wizard(Basically a C++ comment lines(Statrs with /// which is used by the App wizard).
Try to look at the similar code in other files or create a temporary project and copy those scripts.. I have to be carefull while doing this.. I don't think there any other options...
Wish you better luck

I think the code line would be:
if (m_hCloas == INVALID_HANDLE_VALUE)

thanks, i found out the problem, it lies inside the constructor. the problem is solved after i removed the 'if section' code.
does it mean i cant have an if statement inside constructor???

m_hClose = INVALID_HANDLE_VALUE;
m_hClose = CreateEvent (NULL, TRUE, FALSE, NULL);
if ( m_hClose == INVALID_HANDLE_VALUE )
{
