When you save a class into the Gallery, it's implementation and header files (.cpp and .h) are stored away. In the case of a dialog class, it also requires a dialog resource (IDD_EEPROM) to exist in your resource script. Apparently, your dialog resource didn't get saved with the other files.
Like the error code states, the IDD_EEPROM identifier is unknown: check your resource script of what the ID of the dialog is there, and replace the identifier with the correct one.
Additionally, the resource identifiers are not saved with the class. This means that if your dialog class has DDX routines implemented, then those WILL cause the same error. To fix this, you must manually rename the identifiers in DoDataExchange function of your dialog class.

Hello out there,
i have the following problem :
I am using an Active X Image Library (Leadtools), but the methods to read pixel values are much too slow for my purpose.
For example, to read an array of 1000x1000 pixels by the function
long colour = m_Lead.GetPixel(x,y) takes almost 40 seconds. I would net a way to do it in 1 sec or less.
But, the libray allows to copy an image into a DIB very fast (less than a sec for the 1000x1000 image).
The example provided looks like this, where m_Lead1 and m_Lead2 are the image variables associated with the active X control
int MyFlags = COPY_EMPTY + COPY_DIB + COPY_PALETTE;
m_Lead1.Copy(MyFlags);
m_Lead2.Paste(0);
m_Lead2.Reverse();
OLE_HANDLE MyDib = m_Lead2.GetDIB();
m_Lead1.SetDIB(MyDib);
m_Lead1.ForceRepaint();
GlobalFree((HGLOBAL) MyDib);
My question is now, how can I read pixel color intensities from this DIB or OLE HANDLE ? My understanding of Windows bitmap handling is very limited, so a few lines of sample code would be very helpful.
Thank you very much,
ch

Go here CDibData and look at the functions SetPixel, SetValue, GetPixel, and GetValue.
You can also get a copy of Programming Windows by Charles Petzold, which has a section on DIBs.

Has anyone used this successfully?  I need to do something so simple it's pathetic, but I haven't figured out HOW... Here's what I want to do:
I'd like to have a webpage that loads my dll (it's in a cab and all that)... And it's being called like this:
<object classid="clsid:XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX" codebase="XXXXXX.CAB">
<param name="text" value="Yo man!">
</object>
So here's the deal... All I want said application to do... Is to be able to get that text from the param tag!!! Any hints/code snippets in the right direction? I've been having a bugger of a time, and Microsoft's help pages are of NO help for a newb like me!
I know it's probably something easy, but I can't get it to work! Thanks in advance!

Hi,
I have a simple problem with virtual functions and dlls.
See the sample:
class Test
{
public:
Test() { }
~Test() { }
virtual long GetCountRows() { return 1; }
};
class TestA : public Test
{
public:
TestA() { }
~TestA() { }
virtual long GetCountRows() { return 2; }
};
int main(int argc, char* argv[])
{
TestA testa;
long x = testa.GetCountRows();
Test* ptest = &testa;
x = ptest->GetCountRows();
return 0;
}
If this code is in the same area (same source file or lib), it works correct, I get always 2 with GetCountRows().
But if the base class is in a dll, I have problems, because with the second call of GetCountRows() I'll get 1.
Can someone help me?
Thanks...

Which functions are you exporting from the Test class? Make sure you export Test's constructor to ensure the v-table is init-ed in the correct place (ie not the DLL)
|
|
|
|
|
In the dll I export the Test class like this...
class __declspec(dllexport) Test
{
public:
Test() { }
~Test() { }
virtual long GetCountRows() { return 1; }
};

How are you then going about importing this class into the other project? Is the code you provided for Test the actual code? I ask because here you have a inline and virtual method - by defination a virtual function can't be inline, it needs an entry in the v-table to work correctly - though compliers do tend to work with them, its worth a try removing it. If you are just directly including the Test header file into your other project, this may be causing you problems. Try declaring the class as you usually would, and splitting up the deifination. Ie in the .H
class __declspec(dllexport) Test
{
public:
Test();
~Test();
virtual long GetCountRows();
};
Then in the .CPP
Test::Test()
{
}
Test::~Test()
{
}
long Test::GetRowCount()
{
return 1;
}

Hi !
I just wanted to know how is represented an enum internally. Is it an int or a long ?
Thanks !

In Microsoft 32-bit C++, an int and a long are the same size (32-bits). So the answer is "yes".

I think that you need to use VBA. It's more easy and cames with excel....

Does it comes with windows 2000?
How do I operate/run it?

VBA is part of Office, independent of the OS. Check out MSDN for tons of examples.

If you need add same funtions to excel, you need to use VBA, but if you want automate some function from external sources, may be you need to use OLE Automation, How David said... In that case you can use VC++ or VB.

It sounds like you need to use Excel (OLE) Automation. Check out MSDN article Q178749.

Hi,
You can access all of Excels built in functionality by following these steps in an MFC app:
1) Open Class Wizard
2) Click 'Add Class' and select 'From Type Library'
3) Locate 'Excel9.olb' (will vary depending on which version of office u r using)
4) Select all the classes from the list and click ok.
you will now be able to do anything u want with Excel. For more information look at:

Hey guys, maybe an easy question... 
i want to start my programm in maximized mode, how can i do this? i think it´s working with SIZE_MAXIMIZED but i don´t know where and how to use it.
Thanks in advance
Pascal Rexer

In the OnInitDialog() method, post a WM_SYSCOMMAND message with SC_MAXIMIZE in wParam.
Or you can call ShowWindow(SW_SHOWMAXIMIZED).

Hi
I'm moving one of my programs from MSVC 6 to .NET 2003 and
now the librare is changed so that
basic_istream::get calls setstate(failbit) if no elements was extracted
Is there any clean way to go around this, for me a empty string is a normal case?
Regards

Guys I got a question,
When you use the Ambersand sign "&" infront of a variable it means we are passing the address of that variable , right?
what happents when you have the "&" at the end of the variable .
Ex :
if I have a function header
exam(const K&, const V&);
what is the usgae of & in the above?
and what is the difference between this one
exam(const &K, const &V);
|
|

|

Sounds like a reference.
