Since my application should handle different types of document with different toolbars , how can I make one toolbar visible or not after the user creates a new document or switches between documents of different types? Please, help me for it. Thanks
|
|
|
|
|
See the scope of you toolbar variable and ....You can modify the toolbar items...
Second: Yopu can create toolbars you want and then you can Load and Unload thm as the document opens of respective type.

My application supports two document types.I would like to prompt the user for the type of the document he is going to create with appropriate strings, but I don't know how to insert the strings in the default dialog of CWinApp::OnFileNew(). Please, help me for it. Thanks
|
|

I think the strings can be affected by adding new "document template" objects to your application. See the sample and related descriptions for CWinApp::AddDocTemplate function in MSDN.
Perhaps, found the place where the wizard inserted the primary document template for you (somewhere in InitInstance), and add your own templates there.

Give the proper explanation....
You might have disabled them on the UPdate Data. Go through the code again Debug it well and then If you find the problem you can explain it well.

Before showing your second dialog, set a boolean flag, for instance:
CMyDialog dlg;
dlg.mDisableSomeControls = true;
dlg.DoModal();
where mDisableSomeControls is a new member of your CMyDialog, of boolean type, initialized to false in CMyDialog constructor.
Next, in CMyDialog::OnInitDialog function, check the mDisableSomeControls value and disable needed controls, for instance:
BOOL CMyDialog::OnInitDialog()
{
. . .
m_cMyEditBox1.EnableWindow(! mDisableSomeControls);
m_cMyEditBox2.EnableWindow(! mDisableSomeControls);
. . .
}
Hope it helps.

As I understand, you have two menu items -- "Add Data and "Update Data", -- and two handler functions for them in first dialog. In these functions, you probably display your second dialog using:
CMyDialog dlg;
dlg.DoModal();
If this is true, then you have to make changes. In "Add Data" handler, change to:
CMyDialog dlg;
dlg.mDisableSomeControls = false;
dlg.DoModal();
In "Update Data" handler, change to:
CMyDialog dlg;
dlg.mDisableSomeControls = true;
dlg.DoModal();
Then in CMyDialog::OnInitDialog, do something like this:
if(mDisableSomeControls)
{
GetDlgItem(IDC_EDIT1)->EnableWindow(FALSE);
}
Otherwise your program's flow is probably different. Is the menu and menu’s handlers in first dialog, while the controls needed to be disabled are in the second dialog?

can i know wat is mDisableSomeControls is thsi variable of edit box
Please mail me
|
|

|

In above solution, mDisableSomeControls is a variable defined by you in your dialog class. Let us say your second dialog class is CMyDialog, so open corresponding MyDialog.h file and add a definition, like this:
class CMyDialog : public CDialog
{
public:
bool mDisableSomeControls;
. . .
};

If you are making a database application, you should be able to read from the database and check the type of the user -- simple user or administrator. For instance, the "users" data table may contain a column which describes this type, for instance 0 for simple users or 1 for administrators.
After you read the type from the database, you can do something like this:
int type = ...
switch(type)
{
case 0:
{
CMyDialogForSimpleUsers dlg;
dlg.DoModal();
}
break;
case 1:
{
CMyDialogForAdministrators dlg;
dlg.DoModal();
}
break;
}
If you have troubles with databases using C++, I think you can post a separate question to the forum.

but as u told plz tel me abt how i create table for 0 user and 1 for adm

In the same manner as you created your users table containing two columns, you can create a table containing three columns. Just add one more column named "type" and having an integer type.
If you use some database tools, like MySQL Query Browser, it is easy to add a new column to an existing table.

i am sorry for delay i try this code but as value fetched from mysql stored in row which is mysql variable and switch case does not work with this plz tel me . groupid is values 0 and 1 which store in mysql table.
if (!mysql_query(myDB,"select groupid from users"))
res=mysql_store_result(myDB);
row = mysql_fetch_row(res);
{
i = (int) mysql_num_rows( res );
if (i != 1)
{
MessageBox("no match");
mysql_free_result( res ) ;
goto exit_here;
}
}
//int type = ... // the user's type from database
switch(row)
{
case 0: // regular user
{
CAfterone dlg;
dlg.DoModal();
}
break;

{
CAfterone dlg;
dlg.DoModal();
}
break;
}
exit_here:
mysql_close( myDB);
}
Please mail me

I am not an expert in databases, but I think your MySQL statement for determining groupid for a user by username should look like this: "SELECT groupid from users WHERE username='the-user-name'".
MYSQL_ROW contains string, so I think your switch must look like this: switch(atoi(row[0])).

plz sir i distyurb u again but it gives no error but it does not go to second dialog box
plz send me code for this
if (!mysql_query(myDB,"SELECT groupid from users WHERE userid= \'" + user + "\' and \'" + pass + "\'"))
res=mysql_store_result(myDB);
row = mysql_fetch_row(res);
{
i = (int) mysql_num_rows( res );
if (i != 1)
{
MessageBox("no match");
mysql_free_result( res ) ;
goto exit_here;
}
}
switch(atoi(row[0]))
{
case 0: // regular user
{
CAfterone dlg;
dlg.DoModal();
}
break;
case 1: // administrator
{
CAfterone dlg;
dlg.DoModal();
}
break;
}
exit_here:
mysql_close( myDB);
Please mail me

Try to put a breakpoint at switch, or use MessageBox, in order to see which value contains row[0]. If it contains an unexpected NULL or a non-numeric string, then atoi returns 0.
