I appriciate the thought, but C++ doesn't really help, I'm having a hard enough time trying to figure it out in VB.
Thank you though.

Your code is on the right track, except you would use arr(k), not k(0).

b { font-weight: normal; }

I know that it is gonna sound a silly question, i m new in Sql:
Insert into employee (id,name) values (employyeeId,"ramy")
what should i replace employeeide with
note that employyeid is the primarykey of the table
and how this value increments?
Regards
Ramy

If the field employeeid is defined as an IDENTITY field then the numbering is taken care of by sql server - you just need to insert the other field...
e.g.
INSERT INTO Employee (name) VALUE ('ramy')
Then you can find out what the identity of the most recent field added in your code by using the IDENT_CURRENT('Employee') syntax.

Hello,
I am a newbie.
I have read source code of many programs.
They contain some application forms.
I can't know which function is created for user interface or change file time.
I would like to see the easy code to change file time.(Any language C/C++ , Java , Or VB)
I would like to change file attribute
- created time
- last modified time
- last access time
Any one can help me?
Thank you.

Hey guys
I need a simple code :
if i want the cursor to be on : X=20, y =30 the cursor goes to this location (x,y= varible pixles)
how can be this done?
Regards
Ramy
|
|
|
|
|
This should work:
Cursor.Position = New Point(Cursor.Position.X = 20, Cursor.Position.Y = 30)
|
|
|
|
|
When i apply this instruction ,it returns always x=0 and y=0 for cursor position
Cursor.Position = New Point(Cursor.Position.X = 20, Cursor.Position.Y = 30) ,
the error given in cursor position is:qualifying expression will not be evaluated
Regards
Ramy

Are you using VB6 or VB 2005?
|
|
|
|
|
using VB.net 2005
the matter is to i want to move the cursor to a place that i want....
ex: x=20 y=40
and the next step that i want to do :
is to change the color of the pixels there (means X=20,21,...30 and Y=40,41....)
thx

jooooo

as no one reply I try to answer 
You change the current language by changing culture
no exact but take a try
System.Threading.Thread.Currentculture.....("here language name")
Sorry if it doesn't work. By the way I am also trying to search on it.
Take care

Hi everyone,
I created a project in VC++ (Class Library project in visual studio 2005) and I would like to use it in VB .
I defined 2 functions in classlibrary that one of them uses simple data type such as int,bool,.. in input and return value and other one uses data type such as char * .
When I use simple data type ,there is not any problem and I can call the function in vb successfully but when I use another data type such as (char * ,..)I can not call it and even I can not see the function in vb.
My question is about data type conversion between VC++ and VB.
My code is same as below :
//==============================
MyClassLibrary.h
#pragma once
using namespace System;
namespace MyClassLibrary{
public ref class InitCard
{
public :
bool VerifyPin(char *) ; //I can not see this function in VB
bool SetCardAccessKey(int); //I can see and use this function in VB successfully .
};
}
//======================My VB code is same as below :
Imports MyClassLibrary
Dim Jvm_offcard As New MyClassLibrary.InitCard
Jvm_offcard.SetCardAccessKey(2);
//Jvm_offcard.VerifyPin("1234") //there is an error on this line
I would like to know how can I use data type such as (char *,byte array ,string) between VC++ and VB code.
I would appreciate for any help .
Yours sincerely,
Orchid

You need to use the .NET String type rather than char* in your C++. I've not done any C++/CLI but don't you need to have something like
bool VerifyPin(String ^) ;
