Which function(s) are called when loading the values from the resource.h file of a dialog application? Or how to load these values at runtime?
|
|
|
|
|
In the resource.h are only the values as macros defined. The resources reside in a *.rc file as data or as link (*.bmp).
The loading depends on the type of object. Bitmaps are loading with the CBitmap class.
Please read the MSDN or CP-Websites.

Hi!
My source code seems has a memory leak, the MFC Debug mode can tell me the position in memory address and its size.
My question is how can i get its position in source code or the other info that will help me to find the wrong code?
Thanks!!

I'd like to write a program that calculates something but still allows messages to be processed. Essentially I want to write an MFC OpenGL app. Where do I put my function calls? I know I need to create a different thread, but does this mean writing my own class, inheriting it from CWnd and then have it be an object under my Dialog and receive messages from the parent Wnd?

i was studying c++ object oriented programming notes today and have some questions regarding to this problem.. any suggestion is welcome.. thank you!
for this question, i'm supposed to find the implementation error and fix it without changing the interface.
i read thru the codes and realized that the method B::Init() was trying to initialize the private variable, pNum, that belongs to class A(Class B's super class).. I was wondering is there anyway to access to class A's private variable from class B? and also have i missed any other implementation error?
class A
{
public:
A() { Init(); }
virtual ~A() { Destroy(); }
virtual void Init();
virtual void Destroy();
long Get() { return *pNum; }
void Set(long num) { *pNum = num; }
private:
long *pNum;
};
class B : public A
{
public:
B() { Init(); }
virtual ~B() { Destroy(); }
virtual void Init();
virtual void Destroy();
long Get2() { return *pNum; }
void Set2(long num) { *pNum = num; }
private:
long *pNum2;
};
void A::Init()
{
pNum = new long;
}
void A::Destroy()
{
delete pNum;
}
void B::Init()
{
pNum = new long;
pNum2 = new long;
}
void B::Destroy()
{
delete pNum2;
}

B cannot see A's privates. If you made the variable protected, it would be visible to B. Otherwise you can make B a friend class of A, but in this case that would be kind of redundant, unless A has other classes derived from it which should be disallowed from seeing A's private stuff.

I feel real dumb  for having to resort to this but I cannot find what I need to know anywhere.
In an MFC App (VS.NET)I have a button in my dialog box. I thought that when I double click it in design view it would generate the code for the button click event -- then all I would have to do is fill in the code (VS does this on the computers at school). But (at home) when I double click a button in design view Visual Studio gives me the MFC Add Class wizard. I tried adding the code by hand but it didn't work. I think the event I wrote by hand didn't get attached to my button. Anyway...is there a setting in Visual Studio that will chanage this so that when I double click a button in design view the code for a button click event will be generated??
Thanks for you help!

I guess you haven't associated a class with your dialog resource. First you need to do that - associate a CDialog derived class with the dialog resource; only after that will dbl-clicks on control result in their mouse click handlers getting automatically created for you

Ok I did that and it gives me the event but i created a new header file and cpp file. I want the event to be generated in my ...View.cpp file without it creating a seperate .h and .cpp
Do you know how to do that?

If you have it's process handle, you can wait on the handle using one of the WaitForXXXX API calls.
Else if you have the HWND of the window, just do an IsWindow on it and then do a GetWindowText etc... and verify that it;s the same window.

Let say you have computer, named nt...
1) Connect to remote computer:
CString strNetPath("\\\\nt\\MyData");
NETRESOURCE netRc;
ZeroMemory(&netRc, sizeof(netRc));
netRc.dwType = RESOURCETYPE_DISK;
netRc.lpRemoteName = (LPCTSTR) strNetPath;
WNetAddConnection2(&netRC, "Password", "UserName", NULL);
if(dwResult != NO_ERROR)
{
MessageBox( NULL, "Connection Failed", "Yeap", MB_OK);
return;
}
CFile aa.Open("\\\\nt\\mydata\\myfile.txt",CFile::modeRead);

When I add a new record to the Oracle table, I also want to get back to it to update more fields after some process.
Here is an example:
m_pSet->m_strFilter = "";
m_pSet->m_strFilter = "create_date desc";
m_pSet->Requery();
.
.
.
m_pSet->AddNew(); //line1
m_pSet->m_NAME = "Elizabeth"; //line2
m_pSet->Update(); //line3
m_pSet->Requery(); //line4
UpdateData(FALSE); //line5
line5 does not display data from the newly added record.
I tried using the primary key employee_id to locate the record. Unfortunately, employee_id is updated by the Insert trigger.
How can I get back to the newly added record?

Iam not exactly clear of what u want the program to do when Updatedata() is executed .
But when u Add records using AddNew() and execute Update() ,the record which was previously the current becomes the current record after Update() - I hope this is 'nt confusing !!!!!!
eg .
Before AddNew()
Current Record :A ( say)
Now you add record "B" .
Execute Update()
Now
Current Record :A( still it is A)

I see. No wonder I don't see the newly added record as the current record. Plus, If I loop through all the records in the recordset, the new record is not even there unless I do a Requery. Is there an easy way to get to the new record (assuming the recordset is sorted the way that the newly added record is not neccessary the first or the last in the recordset)?

It depends on how you open the recordset .If open it in snapshot mode or in dynaset mode ,ReQuery() is absolutely required .But if yyou open it in dynamic mode ,it is not required .However most of the Databases don't support "dynamic" recordsets .
Evene before Requery() ,u have to use CanRestart () function to check if rthe recordset can be requerried !!!!

Yeah, this has been discussed many times. I think the backspaces go past the beginning of the line because of a problem with how tabs are accounted for.
