Dear All,
I am developing a dialog based application using MFC VC++ Version 6.0 for Windows 2000. The application consists of a TabControl derived from CTabCtrl Class having three tab pages in it. Also, the tabControl has Apply, Cancel , Ok button.
My query is how to communicate between the tabpages data and OK,Apply button ??
Similiar case, like "Display properties" dialog box which appears upon right clicking on the desktop. When we select a background and click on apply or ok button to make the changes, the background color gets changed.
Following is the code to create the tab pages. I have radio buttons in first CGeneralSettings page and I want to do various operation after user selects one of the radio button and clicks OK or APPLY button
///////////////////////////////////
The CMyTabCtrl has following datamember:::::::
class CMyTabCtrl : public CTabCtrl
{
public:
CMyTabCtrl();
CDialog *m_tabPages[3];
int m_tabCurrent;
int m_nNumberOfPages;
...
..};
CMyTabCtrl::CMyTabCtrl()
{
m_tabPages[0]=new CGeneralSettings;
m_tabPages[1]=new CAuthorization;
m_tabPages[2]=new CUnInstallation;
m_nNumberOfPages=3;
}
CMyTabCtrl::~CMyTabCtrl()
{
for(int nCount=0; nCount < m_nNumberOfPages; nCount++){
delete m_tabPages[nCount];
}
}
///////////////////////////
Please feel free to ask further clarifications in this regards,
Regards,
Rohit

All you need is apply,ok method implemented in each tab pages, can call them when you clicked on apply button on the tabcontrol (in a loop maybe).

I have created a microsoft chart graph. I need to plot around 1400 rows in x- axis which makes graph unclear. Can anybody suggest what solution i can find out to solve the problem?
How can i add a scroll bar to graph so that all the 1400 values can be seen clearly....?
OR is there any other active-x control in MFC which i can use to plot a 3D and 2D graphs.?
Please let me know ASAP.
Thanks in advance

not possible with default image control
look around CP for a subclass which does this...
Actually, thats a darn good idea for a control if one doesn't already exist

Probably not using the picture tool inside the dialogbox editor...you'd have to use an activex or subclass that picture tool and render a jpeg instead

I have an MFC executable and an ATL DLL which supports MFC as well.
When the DLL calls AfxGetModuleState it gets the EXE's ModuleState class instead of it's own.
Why does this happen ? What am I missing ?
|
|
|
|
|
is it causing a problem ?

Yes because when loading resources (AfxFindStringResourceHandle for example), AfxGetModuleState is called.
So, my DLL tries to load a String resource for example, and tries to run through all of the EXE's resource-handles (because AfxGetModuleState returns the EXE's module object) instead of it's own list of resource-handles (stored in it's own module-object).
Am I missing something ?
Does the DLL really have it's own moduleobject ? I'm pretty sure it does, but why isn't it returned then ?
thanks

When you are loading the resource string, dont you think you need module instance handle of the dll???

You can, but the better way is to use AfxFindStringResourceHandle which not only looks in your resource-hinstance but also traverses the CDynLinkLibrary list and any other relevant resource-handles, that's the way to use several resource-dlls at the same time.
Only that it doesn't work in this specific scenario because the module returned is the EXE's one and not the DLLs one...

Did you insert
AFX_MANAGE_STATE(AfxGetStaticModuleState());
before any MFC call you do from within a DLL function?

Nope
Can you tell me more about this ?
What does it do exactly ? Is it possible to do it once per module and not before every call ?
thanks

Ok I'm starting to get it,
There is no other solution except for placing this in all my methods that perform MFC calls ? Isn't this abit weird ?
|
|
|
|

AFAIK this is the only solution. I don't think it's weird cause you only want to change the module state during the function call, and then set it back to the main application. And adding one line of code isn't too bad, is it ?

In the begining of every function that uses an MFC method which in turn uses this DLL's own resources ?
I think it sounds terrible Having to remember to do this, and having other people rememebr to do this. Not to mention having my code cluttered by this line all the time...
I want my module to always use the same AFX_MODULE_THINGY, why can't the AFX methods do AfxGetStaticModuleState(), that is my question actually. Why did they leave it this way ?

Unfortunately (?) I was never a part of the development teams that invented MFC and the related techniques.
So I fear this is a question I can't answer you - I just take it as is, and every time my DLL does some weird things the 'AFX_MODULE_THINGY' is the first thing that comes to me. Hope you'll reach that state soon, too.

No, it is only needed by those functions that load resources from the DLL. Your DLL can use MFC all day long, but if it ever needs to load one of its own resources, it must use the AFX_MANAGE_STATE() macro.

Hi All,
I was trying to make a code similar to this work.
template <class t=""> class myclass
{
private:
t num;
public:
myclass() {}
~myclass() {}
};
class myclass1
{
public:
void abc(myclass <class t="">* obj)
{
}
};
int main(int argc, char* argv[])
{
myclass <int> obj;
myclass1 obj1;
obj1.abc(&obj);
return 0;
}
My basic idea is to have a template class myclass (which will take structure as template parameter). Now have another class myclass1 which will have a function taking this template class as one parameter. I want to make this member function of class myclass1 generic. i.e depending on the object of class myclass I create, this function should work.
Am getting compilation error.
Can we do such a thing at all with templates?
Thanks
Rajdeep
