Huum, I don't understand what you mean by templates class ?
The class I'm deriving from is defined in the main app...
The derived class is successfully created by the DLL so that does not seem to be the problem but when I try to create it's window using Create(...), with parent set to the main apps window, the functions returns 0. Could there be some form of resource problem even though the class derived in the DLL is just a CStatic ?

Check whether the provided parent of the main apps is correct is valid in the DLL.
Knock out 't' from can't,
You can if you think you can
|
|
|
|
|
Yes, the provided parent has correct type (CView) and seems valid.

How to Create Array of Labels on the Run-Time ?
Best Regards...
|
|
|
|
|
Use new or a vector from the STL.
Now if you want a more precise answer, you have to ask a precise question also. What is a label exactly (it can be a lot of different things). And describe your problem in detial.

A label is a static control :
Assuming you mean a static control when you say label.....
CStatic *st=new CStatic();
st->Create("hello",SS_SIMPLE,CRect(0,0,100,100),this,-1);
st->ShowWindow (SW_SHOW);
Somethings seem HARD to do, until we know how to do them.

This sample create an array of 10 labels:
CArray< CStatic * > mArrayOfLabels;
for( int i = 0; i < 10; ++i)
{
CStatic * label = new CStatic();
label->Create("Label", WS_VISIBLE, CRect(CPoint(0, i * 32), CSize(100, 32)), this, IDC_STATIC);
mArrayOfLabels.Add(label);
}

Its Not work
I use .NET 2005
Not: .2005 not accept * instead of I use ^

(The sample was for C++ ordinary MFC projects).

wchar_t *username = L"aaaaaaaa.t35.com";<br />
wchar_t *password = L"gaaaaa";<br />
wchar_t upFileName[] = L"test.txt";<br />
wchar_t dir[] = L"test";<br />
HINTERNET hInternet;<br />
HINTERNET ftp;<br />
<br />
void upload(void);<br />
<br />
<br />

<br />
<br />
<br />
hInternet = InternetOpen( NULL, 1, NULL , NULL,1);<br />
<br />
ftp = InternetConnect(hInternet, server,21, username, password, 1,1,1);<br />
FtpCreateDirectory( ftp, dir );<br />
FtpSetCurrentDirectory(ftp, dir);<br />
<br />
FtpPutFile( ftp, upFileName,upFileName,2, NULL);<br />
<br />
InternetCloseHandle(ftp);<br />
InternetCloseHandle( hInternet);<br />
<br />
<br />
}
but i get these error no matter i tried in many computer (which installs both Visual studio 98 and Visual studio 2005), i dont' know why? can't any one help me?

In the additional lib's have you specified Wininet.lib?
You also need to include the file wininet.h in the file where you are using the API functions.

--> does it mean i have to include wininet.h in the "upload" funtion?
|
|
|
|
|
As it seems, that's not the problem.
The errors you get are all link errors, so they originates from not linking wininet.lib
|
|
|
|
|
but i need detail solution? can you or anyone help me ? please!

If you got VC 6 (as me), do this:
1.
Press AltF7 to get to "Project"->"Settings"
2.
In the left window (top), select "All Configurations"
3.
Click on the "Link" tab
4.
Select "Category" Input
5.
In the edit line under "Object/Library modules", go to the end of the line.
6.
write a space, followed by wininet.lib
7.
Click the "OK" button
Build (or rebuild) the project.

|
|
|
|
Have you Selected the proper project. Because after including the files Wininet.h and Wininet.lib the program runs perfectly well.
And if you don't include it It will give the errors as you have described

Just add the following in your Stdafx.h header file
#pragma comment(lib, "wininet");
Knock out 't' from can't,
You can if you think you can

 Of course. I'm using it all the time, and still I forgot when I wrote my answer

Open the Properties dialog of your project and go to Linker --> Input --> Additional Dependencies fiels. Type here "Wininet.lib" (use space as separator, if there are other items). Repeat this for Debug and Release configurations. Then try to build the project.
The libraries and headers you need usually are described in the documentation.
Hope it helps.

No you only need to include the wininet.h file where you are using the API functions at the top where you are including rest of the files
Alternatively you can include this wininet.h file in the stdafx.h file if you are using this API at various places in your project
