Actually, it won't. "virtual inline" makes no sense and the inline specifier will be ignored.
Virtual functions let an object decide at runtime which particular implementation of a method should be invoked. If you have a pointer to the base object and call a virtual method, there is no way to know at compile time what type of object will be present at the actual time of the call. Hence, the compiler won't be able to figure out which implementation of the function to compile inline.

This is of course, correct. However, if you use an object of the class in a non-polymorphic manner (say, create it on the stack), the compiler can figure out which object is used and inline the function.
Therefore, "virtual inline" actually makes sense, and will not be ignored

I need a decrytion routine to decrypt the password, since i can get the username but not the password.
void __fastcall TForm1::SQLConnectionBeforeConnect(TObject *Sender)
{
if (SQLConnection1->LoginPrompt == false)
{
SQLConnection1->Params->Values["User_Name"] = "SYSDBA";
SQLConnection1->Params->Values["Password"] =
Decrypt(SQLConnection1->Params->Values["Password"]);
}
}
Many Thanks,
Priya

Ask the user who is the system adminstrator of the DB.

Hi there,
I think you did not really get my question. I need to get a decrypt routine to be able to get the password, as shown in the code. I can get the username but i cannot retrieve the password.
And there is no sys admin for the db for the moment.
Many Thanks,
Priya

Priya dear,
I understood exactly what you asked for.
if passwords can be decrypted then Oracle will be out of business soon.
Its plain not possible and not rite.

Hi again,
I reformulate my question:
When using a datamodule and a database (Tdatabase) how can I set the User Name and Password by codes?
Eg: DataModule->Database->.......
Regards,
Priya

if the database security is not urs, then yous should use some API or function provided by the oracle to change or set the password.

I am not using Oracle but SQL Server, and i need to get the password. I don't think that has anything to do with the database security. The code i sent you before allows me to retrieve the username but not the password. But i need to get the password so that i can set it in Windows Registry. Where i got the code, there was something mentioned about needing a decrypt routine to be able to get the password. That's what i require.
Thanks,
Priya

I think you should ask in some SQL Server forum, this forum is dedicated for VC++.

Aren't there any forum on Boralnd C++ in codeproject? Could you guide to one forum on Borland C++ or SQL Server?
Thanks

How to download files from an FTP server using multiple threads in VC++?Please any one help me.....with code for that...
|
|
|
|
|
i dont think anyone is going to give you the code to do that, but here is the clue, some FTP servers have enabled partial download of the file. So you create multiple FTP connection to the server and initiate partial download of the file from different seciont of the file.
Afer downloading all the sections of the fine in your local machine, concatenate the files.

I want to get full multi line text file...By using fscanf..
FILE *f;
CString str=_T("");
CString temp=_T("");
while((fscanf f,"%s",temp)!=EOF)
str=str+temp;
.
.
.
.
this is my code...but i cudn't get full text.It shows only the last line in my full text..
How can i get full text line

It is better to use fgets[^] instead of fscanf. Because fscanf read formatted data, so, if it encouters a white space, this will be considere as a new 'variable' and thus will stop reading the data if it doesn't need to read anything else.

What is the size of
int
char
float
in Windows 2000 ??

void main(void) {
printf("int : %d\n", sizeof(int));
printf("char : %d\n", sizeof(char));
printf("float : %d\n", sizeof(float));
}
will output :
int : 4
char : 1
float : 4
but notice this : an int is much dependant of the processor architecture than the OS. so, under Windows2000, it may be 4 bytes if the processor handles 32 bits ints, or 8 bytes if it handles 64 bits ints...

What about the compiler.
