Hi,
CEdit *pEdit = (CEdit *)GetDlgItem(IDC_EDIT1);
pEdit->ShowWindow(SW_HIDE);
// pEdit->EnableWindow(FALSE);

Hello, the codegurus around the world.
CMyDialog dlg;
if (!dlg.m_edit.GetSafeHwnd())
MessageBox ("Sorry this", "Test");
dlg.DoModal();
Use the code - ShowWindow in BOOL CMyDialog::OnInitDialog (),
or use the resouce editor to take off the check box of Visible in m_edit.
Have a nice day!

Well, how do you do it then,
I want when the user clicks a certain radio button, an edit box to appear, but until the radio hasn't been clicked, to stay hidden?

Hello, the codegurus around the world.;)
Well, first of all, you should say clearly what you want.
I just created one radio button to show or hide the edit box.
If we open the dialog, the edit box is shown, and the radio button
title is "Hide the edit box".
If we click the radio button, the edit box disappers, and the raio button title is "Show the edit box".
After we click the radio button, the radio button is unchecked in two seconds.
void CSlidingDlg::OnRadio1()
{
CButton *rdButton = (CButton*)GetDlgItem (IDC_RADIO1);
ASSERT(rdButton);
CEdit *editbox = (CEdit*)GetDlgItem (IDC_EDIT1);
ASSERT(editbox);
editbox->IsWindowVisible() ? editbox->ShowWindow (SW_HIDE) :
editbox->ShowWindow (SW_SHOW);
rdButton->SetWindowText (editbox->IsWindowVisible() ? "Hide the edit box" : "Show the edit box");
Sleep (2000);
rdButton->SetCheck(0);
}
Have a nice day!

In the dialog resource, just untick the Visible property of the Edit control. Then, use ShowWindow(SW_SHOW) to show it again when the radio button is clicked.

Wondering how to determine the number of elements stored in a CStringArray. I want to get back how elements hold data not how many it's capable of holding.
If I use SetSize(10, 5) to set the initial size of the array to 10 elements and then add 7 actual elements I get the following results.
GetSize() returns 10 while GetUpperBound() returns 9, when I want to get 7 and 6 respectively.
Is this possible?

I don't think a CStringArray knows how many strings you have added. It knows the size, but not how many of the pointers you actually use.
Why don't you use CStringList if you want that functionallity?

cause I'm dumb, stupid and didn't know it existed. Now you have pointed it out to me I will look it up, but not until tomorrow. I have waited until midnight Sunday to get an answer, better get to bed if I'm going to make in it to work on time.
Once again thanks for the answer.

I am trying to package a reusable class library in a win32 dll
however I have run into a problem,
Class B and B2 derive from class A, heres the simplified code:
class __declspec( dllexport ) A
{
public:
A();
virtual ~A();
virtual void SomeFunc(void) = 0;
};
class __declspec( dllexport ) B : public A
{
public:
B();
virtual ~B();
void SomeFunc(void);
};
class __declspec( dllexport ) B2 : public A
{
public:
B2();
virtual ~B2();
void SomeFunc(void);
};
A::A()
{
cout << "A constructor." << endl;
}
A::~A()
{
cout << "A destructor." << endl;
}
B::B()
{
cout << "B constructor." << endl;
}
B::~B()
{
cout << "B destructor." << endl;
}
void B::SomeFunc(void)
{
cout << "B::SomeFunc()" << endl;
}
B2::B2()
{
cout << "B2 constructor." << endl;
}
B2::~B2()
{
cout << "B2 destructor." << endl;
}
void B2::SomeFunc(void)
{
cout << "B2::SomeFunc()" << endl;
}
This compiles into a DLL without any problems. However when
I attempt to use it (I have linked to the .lib and put the
.dll in the executable directory) using the following code:
#include "A.h"
#include "B.h"
#include "B2.h"
int main(void)
{
A* test = NULL;
test = new B();
test->SomeFunc();
delete test;
return 0;
}
I get the output as expected:
A constructor.
B constructor.
B::SomeFunc()
B destructor.
A destructor.
But then a nasty debug assertion failure:
Debug Asserion Failed.
File: dbgheap.c
Expression: _pFirstBlock == pHead
Oddly enough, if I comment out delete test; the assertion failure does not occur, but I dont want memory leaks in my programs. I know that converting it too a COM dll and using interfaces would problably be the best solution, however I want to first learn how to create normal dlls before I mess with making them COM compliant.

Have you tried calling delete []? Call it with the brackets and see if the same problem occurs.
|
|
|
|

Check if the DLL is built with the same C runtime
library version as the program you're using it from
(i.e. Multithreaded or not, static ot dynamic, debug
or release). If versions differ this kind of problems
can occur

I was wondering whether Visual Interdev is itself an MFC app and if so, I was wondering what MFC classes is it derived from?
thanks

Visual C++ is a MFC application, so I guess Interdev is too...

Hi everyone,
I hope programmers here can help me. One of my beta-testers said that he had encountered a problem. The problem is the following: Windows XP does not work. Can anyone help me to fix it? Here is the source code of Windows XP:

Hi folks,
I hope one of you out there can help me with a small problem.
Does anyone know how to override the MFC default icons in my MFC app wizard application that Microsoft kindly provide? It's the small icon that appears at the top left corner of the main window that I want to replace in particular.
I even removed them from the resources and replaced them with my own icons, but to no avail. I had a look at the MSDN library help for PreCreateWindow and CREATESTRUCT but there's nothing obvious there.
Any suggestions would be great.
Cheers, Stephen.

Hi
I need to be able to store extremely long values temporarly for encryption. The problem at the moment is i can't find anyway of doing it and a ULONG is far to small. I also can't just put it into a string since i need to be able to performs some mathematical functions on it.
Basically what i need to do is have a variable capable of storing a Unsigned Long to the power if a 100 digit number. I also need to be able to store the number that is going to be the power.
So far i have wondered if there is anyway of declaring a pointer and manually designanting its size in bytes rather then defining it to store a unsigned long etc.
The other idea i had is if there is anyway to define your own data types and specify there size or if i could somehow add two existing variables together like to unsigned longs that would give me a whole new data type that stored 64bits rather then 32.
Thanks for all the Help

Hello,
How would it be possible to "extend" any SIP of any appplication ? I mean I would like to insert a processing that would modify/verify each user input from any kind of SIP, of any application, before the input string is sent to the application currently owning the SIP.
Do I have to write a DLL, how could it work ? I plan this of course under Windows CE. Do one need something related to hooking (I know that is very restricted under Windows CE) ?
Thank's in advance.

You should get the book "Programming Microsoft Windows CE" by Douglas Boling, from MS Press. It explains a lot about SIP's, also how to make them...

Hi,
I have this book (unfortunaltely not physically accessible for the moment )
And if I remember it describes how to create a new kind of SIP, but not how to extend an already existing one, isn't it ?
