Yes, of course. You've to use, for instance, CreateWindowEx [^] function.

MSDN has a lot of examples about, see, for instance, the Using Buttons [^] topic.

If it's only a handful, why not create them all at design time, and then show/hide them accordingly (ie, some condition)? Much, much easier than creating them at runtime.

As it is a requirement we can not do this.

My program crashes on a client's pc (with XP) on this 3 lines (on any other pc it correcly runs):
m_pMainWnd->ShowWindow(SW_SHOWMAXIMIZED);
m_pMainWnd->SetForegroundWindow();
m_pMainWnd->UpdateWindow();
They are default instruction in the initialization function (InitInstance) of a MFC program.
My antivirus (COMODO) tells a warning on UpdateWindow because when run trys to install a global hook on "atioglxx.dll" (It looks a dll from my ATI video board). If I do not permit this the program stops, else runs perfectly.
I'm quite sure that some setting of the antivirus of the client is locking this function! Or that his video-board isn't so compatible with this function.
Why this hook? Is it important? can I avoid this to let the program run on every pc?
Any other solution?
Of course there is the easy way (but not the real solution) to tell to the user to disable the antivirus (I think it is Norton)
Thanks

Hi All
I am try to get values from Mysql database.I am using pRecordset class for get data from Mysql.But it's generate error while the data type is Decimal.
strContent = (char *) (_bstr_t) pRecordset->Fields->GetItem((_bstr_t)"Price")->Value;
Table is
create table test(A TINYINT(100), B SMALLINT(100), C MEDIUMINT(100), D INT(100), E BIGINT(100), F FLOAT(100,10),
G DOUBLE(100,10), H DECIMAL(65,20));
insert into test(A,B,C,D,E,F,G,H)values(65,645,365,31311,87655498,46546547.650909090,475735375734573.0000,5323423424.00004343434300000);

Hi Experts,
When I declare a Object of the class, How it store into memory i.e which memory segment it used?
|
|
|
|

MPTP wrote: which memory segment it used?
I presume you are trying to distinguish whether it is stored on the heap or the stack. If you create an object via new() then it goes to the heap. If it is a local variable it goes on the stack.

If you have created the object like. Myclass m;
the object is stored on the stack
if you have done-- Myclass* m = new Myclass();
the memory is allocated from the heap.
You need to google first, if you have "It's urgent please" mentioned in your question.

the runtime takes care which memory is used. Every time a object is created some memory will be used. You can get the information about that getting the address of of the object.
In C++ you 3 ways to create objects
Sample code:
void sampleFunc()
{
Object obj1;//Stacke with automatic destruction
Object *addrObj = &obj1;//getting the address of memory
//do not
//delete addrObj;//Bug
Object *pObj = new Object();//Heap and manuell destrucion needed!!!
delete pObj;// to avoid memory leak;
}
Press F1 for help or google it.

As replied by the others here, whether stack or heap is used is not dependent on a class.
For memory allocation, a class is nothing but a chunk of a particular size.
In fact it is the same for a structure, class, fundamental types, arrays etc.
Dynamic allocation (new, malloc etc.) allocate memory on the heap.
Function arguments and local variables use a stack.
A separate stack exists for each thread.
Initialized global variables are created in a separate section in the the executable.

Start with this:
INSERT INTO pdpstate(setid)VALUES('0')
If that works, add another field/value pair. Continue until syntax error appears.

Hi , I have an application that uses on document structure, am converting to to MDI from SDI. I've got that part handled except for child windows. I want to create a child window for different instances of the application, like add order, add location, add machine, etc... How could I go about creating different child windows that could be open at the same time as the other ones?

i has been created one login.aspzx page and one master.aspx page
when i login ,i m directly redirect to master page.master page contain logout button(linkbutten).
when clicked on logout button,the page has redirect to login page.
My problem is that,in that (after i clicked the logout button)when i clicked the "Back" it will move to master page.
i want clear the session?????
login.aspx page :
protected void buttonLogin_Click(object sender, EventArgs e)
{
if (string.IsNullOrEmpty(TextBox1.Text))
{ //Focus box before showing a message
// textBoxUsername.Focus();
TextBox1.Focus();
//MessageBox.Show("Enter your username", this.Text, MessageBoxButtons.OK, MessageBoxIcon.Information);
Response.Write("<script> alert('Enter your username');</script>");
//Focus again afterwards, sometimes people double click message boxes and select another control accidentally
TextBox1.Focus();
// textBoxUsername.Focus();
return;
}
else if (string.IsNullOrEmpty(TextBox2.Text))
{
// textBoxPassword.Focus();
TextBox2.Focus();
// MessageBox.Show("Enter your password", this.Text, MessageBoxButtons.OK, MessageBoxIcon.Information);
Response.Write("<script> alert('Enter your password');</script>");
TextBox2.Focus();
// textBoxPassword.Focus();
return;
}
using (DataTable dt = LookupUser(TextBox1.Text))
{
if (dt.Rows.Count == 0)
{
TextBox1.Focus();
// MessageBox.Show("Invalid username.", this.Text, MessageBoxButtons.OK, MessageBoxIcon.Error);
Response.Write("<script> alert('Invalid username.');</script>");
TextBox1.Focus();
return;
}
else
{
//Always compare the resulting crypto string or hash value, never the decrypted value
//By doing that you never make a call to Decrypt() and the application is harder to
//reverse engineer. I included the Decrypt() method here for informational purposes
//only. I do not recommend shipping an assembly with Decrypt() methods.
string dbPassword = Convert.ToString(dt.Rows[0]["Password"])…
string appPassword = (TextBox2.Text);
//we store the password as encrypted in the DB
if (string.Compare(dbPassword, appPassword) == 0)
{
Session.Add("islogin", true);
Response.Redirect("Firstmain.aspx");
}
else
{
//You may want to use the same error message so they can't tell which field they got wrong
TextBox2.Focus();
// MessageBox.Show("Invalid Password", this.Text, MessageBoxButtons.OK, MessageBoxIcon.Information);
Response.Write("<script> alert('Invalid Password');</script>");
TextBox2.Focus();
return;
}
}
}
}
master page :
protected void Page_Load(object sender, EventArgs e)
{
lblTime.Text = DateTime.Now.ToLongDateString();
if ((Session["islogin"] == null) || (Session["islogin"] == ""))
{
Response.Redirect("frmLogin.aspx");
}
}
//protected void LoginStatus1_LoggingOut(object sender, LoginCancelEventArgs e)
//{
// Response.Write("LoggingOut event. Don't go away now.");
// e.Cancel = true;
//}
protected void LinkButton1_Click(object sender, EventArgs e)
{
Session.Remove("islogin");
Session.Clear();
Response.Redirect("frmlogin.aspx");
}
