Hi. It can be total removed menu toolbar from an MDI project ? I do this thing in an SDI project , but in MDI failed ...
|
|
|
|
|
You can hide a menubar by this:
m_wndMenuBar.ShowWindow(SW_HIDE);
|
|
|
|
|
m_wndMenuBar is not member data of CMainFrame ....
|
|
|
|
|
I work only in VC6 , that's why m_wndMenuBar is not data member of CMainFrame ...
|
|

How do i know that my process is running as an administrator ??
Thanks in advance...

How can CreateProcess() be used to tell if a process is being run as administrator?

Hey Everyone. My problem is it seems that when I create a .cpp file for a .hpp, when dealing with inheritance, I get the same error which is :

here is an example of what I am trying to get complied:
the header file
#ifndef GEOGROUP_HPP
#define GEOGROUP_HPP
#include "geo.hpp"
#include <vector>
namespace Geo
{
Class GeoGroup : public GeoObj
{
protected:
std::vector<GeoObj*> elems;
public:
GeoGroup(const Coord& p = Coord(0,0)) : GeoObj(p)
{
}
virtual void draw() const;
virtual void add(GeoObj&);
virtual bool remove(GeoObj&);
virtual ~GeoGroup()
{
}
};
}
#endif //GEOGROUP_HPP
and the dotC file:
#include "geogroup.hpp"
#include <algorithm>
namespace Geo
{
void GeoGroup::draw() const
{
for (unsigned i = 0 ; i < elems.size(); ++i)
{
elems[i]->move(refpoint);
elems[i]->draw();
elems[i]->move(-refpoint);
}
}
bool GeoGroup::remove(GeoObj& obj)
{
std::vector<GeoObj*>::iterator pos;
pos = std::find(elems.begin(), elems.end(), &obj);
if (pos != elems.end())
{
elems.erase(pos);
return true;
}
else
{
return false;
}
}
}
This seems to me to be a linking problem, and also I realized that I might have something to do with having multiple .hpp and multiple .cpp implementation files.
Anyone have an idea on what I am doing wrong?
Thanks,
RobNO.

The keyword class should have a lower-case 'c'.

when the first error message says "missing ;" it is a compiler error, not a linking problem.

I have an HMENU that shows a typical context menu.
What I want to do is make a large context menu like win98 start menu.
Any particular method?

I don't work with MFC. Is there a way to do it in C within the native API?
|
|
|
|

Well, since MFC is just a wrapper around the API, i'd say yes, in my oppinion what you need is an owner drawn menu, i think this[^] should help.

Hi,
In Internet Explorer, when I click on a link and go back to the previous site I am exactly at the same position of the document where I left. Even the link I clicked is still marked by a thin border.
I have an application where I keep track on the history on my own. Now I need exactly the same behaviour.
I think i need to save the "state" (scrollposition and "marked" link) in my history array and restore it afterwards when I load the old site again.
Does anybody know how to achieve this?
If this is hopeless it would also be enough to just save to current (scroll-)position. However, the loaded documents are complex with different divs which have overflow:auto, overflow:hidden etc. So I can't just get_body, query IHTMLTextContainer and afterwards get_scrollTop etc. because those would be the scroll stuff from the document itself...
Thank you for any hints!

I want to create a dll which can create custom controls like custom dialog and custom button etc..
Can anybody tell me how to do that..
Please help me regarding this..
Thanks

As with most things, break the problem down into smaller parts.
Can you make a DLL?
Are you thinking of MFC? In which case, export a CMyWnd class, and do RegisterWindowClass (*) in the constructor.
If it's win32, take a leaf out of InitCommonControls, and export a function from your dll that registers the windows classes.
The first two parts have good articles here on CP.
You also need to work out what the problem you are solving is - that will have a big effect on your solution.

(*) from memory. Look up appropriate function!

Ys I can create the DLL but I want to know how we can add the custom class for the Button which is drived from CButton in the DLL, so that I can use that dll in my sdi application to create the button.
Thanks,
|

OK, so you can make a DLL.... Check.
And this is in MFC... Check.
So, there's only a few simple things to do:
1/ Make a header somewhere that both the dll code, and the later exe code can read. (I have a workspace include directory, normally).
Near the top, have code like this:
#ifdef IAINDLL
#define IAINEXPORT __declspec(dllexport)
#else
#define IAINEXPORT __declspec(dllimport)
#endif
When you write your CButton inheriting class, start like this:
class IAINEXPORT CIainButton : public CButton
{
};
In your project settings, make sure to add the following symbol to the defines: IAINDLL. That way, when code in the DLL sees the header file, it says "oh, this will be exported!", and when code elsewhere sees the header file, it says "aha, I will link to these class functions".
If you don't know how to write a custom CButton class, then Button Controls[^] is full of examples for you to follow.
Good luck,
Iain.

Hi,
I want to write an addin for visual studio, that will display a tooltip showing a certain datamember, when I hover the mouse over a MyClass object f.ex. Is this at all possible? I don't know how to get the information about what the mouse is hovering over. I need some links to reference docs. Thanks!

_Worksheet objSheet;
Range objRange;
-----------some code here----------------
objRange = objSheet.GetRange(COleVariant(A1),COleVariant(K4));
//at the following line I got the memory leak memory of my programme get increase
ret = objRange.GetValue2();
How to solve that problem

How do you know there is a leak? What are the types of the variables?
