The help text for C2600 pretty much sums it up: your class is missing a default constructor.
class MyNewClass
{
public :
MyNewClass();
static pair pairTable[20];
static int pairCount;
};
|
|
|
|
|
Sorry I forgot to mention , my class does have the constructor specified in the .cpp file .
|
|
|
|

Have you defined pairTable in the cpp file as:
pair MyNewClass::pairTable[20];
If you haven't, it will probably result in an unresolved external linker error. If this isn't the problem, post what the actual linker error is - it might make it a bit easier to solve.

think of it this way: a static member variable (different from a static member function) exists outside the lifetime of any single instance of the class it's declared in. therefore you need to give it a place to live outside the class. by adding that single line to the cpp, you've given it a place to live. the line in the header only tells the compiler "this variable will be of this type, i'll allocate space for it somewhere else".
another way to think of statics is that they're basically global variables that can only be addressed in the context of the class they're declared in: cFoo::myVariable.

Hello,
I have an application that show multiples forms. They show ok on the task bar with but when there is not more space on the taskbar WinXP group them together and them the name that shows on the taskbar is CMYApp instead of the application title. I don’t have a problem with the grouping but I will like to show the title of my application not CMyApp.
Any ideas?
|
|
|
|
|
What is the title of your application as it should be displayed?
|
|
|
|
|
|
So when there are but a few windows in the taskbar, you see "Payroll Reports" but when there are multiple windows in the taskbar, you see "CMyApp" instead. Is that correct?
|
|
|
|
|
|
Can you provide a few screen shots that exhibit the problem? I've never heard of such a thing.

Hello,
I have an application that starts with a CListView on the list view the user can click on items and then another frame will show but this time with a CFormView. The user can have more than one CFormView open at any time. Since the user can have more than one CFormView open I don't want them to show on the task bar.
Any help on show to do this. I found an example but it disables the main view and I need that view active.

SetFont(), or modify the template in the .RC file.

I have a CFormView Project.
I'm trying to call a function which is located in LeftMenu.cpp which is my implementation file
(CLeftMenu::CLeftMenu()
: CFormView(CLeftMenu::IDD)), from AnonWasher.cpp which Defines the class behaviors for the application.(CAnonWasherApp)
This is the function that I'm trying to call:
void CLeftMenu::GetCheckedItems()
{
char *checkedItems=NULL;
if( m_hWnd != NULL )
{
CMainFrame *main = (CMainFrame*)m_hWnd;
checkedItems=main->GetCheckedArray();
}
}
When I call GetCheckedItems from AnonWasher, I get undeclared Identifier error.
I don't know how I could do this.

You are failing to #include a .H file. Which line is the compiler complaining about?
|
|
|
|
|
I have all the .h files. Could there be any other problems?
Thanks.
|
|
|
|
|
Having them and #including them are two different things.
|
|
|
|
|
Yes, I have all the #include .h files both my classes.
|
|
|
|
|
Ok, what about my other question regarding the compiler error?
|
|
|
|
|
It was complaining about GetCheckedItems();
|
|
|
|
|
At the top of anonwasher.cpp, do you have #include "leftmenu.h"?
|
|
|
|
|
Yes, I do have the #include "leftmenu.h" at top of anonwasher.cpp.
Maybe I need a pointer to that class.
|
|
|
|
|
Yes, your CAnonWasherApp class will need a CLeftMenu object in order to access the GetCheckedItems() method. Whether it is a pointer or not is up to you and the project's design.

I know this isn't really the place to be asking but since a lot of you probably do programming as a job or something i guess a lot of you own a handheld/PDA. I'm thinking of buying one of the nifty little things myself since i am going to uni to study informatica. What i really like about them is that they basically are full machines for which you can program with only one crucial difference from a full grown PC: You can't choose what OS u install on it (allthough that might change, but not anytime soon i guess). I did a lot of reading on the different OS's but i can't seem to make up my mind. Currently, i'm considering Pocket PC, Palm OS and Symbian. But they all seem to have some downsides. Like i thought about maybe waiting untill smart phones reached the market but it seems Microsoft is charging a lot for the SDK. I think they should provide this free as it is part of the functionality of the product that u can write your own programs for it. Of course the big advantage would be that it is Windows-like and it is probably most compatible with the real Windows versions so programming would go without much hassle. Programming for the Palm OS seems to be quite easy too but for Symbian it seems to be a bit more difficult. I don't really have an idea of this because i don't own a device yet. But i would just like to ask for some opinions on what u people would advise through personal experience.
Thanks
P.S.: if u don't think i should be asking here just tell me to get lost lol
