You can make the following, Project/Add To Project/Componentes And Controls
Then select Visal C++ Componentes and then Splash screen...
That will add you a Splash Screen component in yout project... It's a good sample to start

When I try to open the same file 20 times (without closing), I get a runtime error. Is there a way to workaround that? Im working with COM, so is it a COM-specific limitation? Thanks
|

Regardless of why the runtime error is occurring, I believe you should rethink what you are doing. I can't think of a single reason to open the same file twenty times. Even if you have 20 threads doing I/O against the file, there's got to be a better approach than letting each thread open the file on its own.

Please help me. This is driving me insane.
In the beginging of my myfile.cpp, I add this:
#include <Afxtempl.h>
Then I declared a global variable:
CArray < unsigned char, unsigned char > g_ubArrayReceived;
later, in a function, I called this:
if ( g_ubArrayReceived.IsEmpty() )
xxxxx;
I tried to compile, but VC++ 6.0 tell me that:
"error C2039: 'IsEmpty' : is not a member of 'CArray<unsigned char,unsigned char>'"
what????  what's wrong with me?

Cos he is right!
Check CArray::GetSize
Papa
while (TRUE)
Papa.WillLove ( Bebe ) ;
|
|
|
|
|
well, that's a good alternative. I can use GetSize().
But on MSDN, it does have this:
Determines whether the array is empty.
BOOL IsEmpty( ) const;
Return Value
Nonzero if the array contains no elements; otherwise 0.
|
|
|
|
|
IsEmpty is not a member of CArray, but is for CList, CMap, CMapStringToOb CObList and CString!
Papa
while (TRUE)
Papa.WillLove ( Bebe ) ;
|
|
|
|
|
well, I think Microsoft should add this to its CArray class.
Thank you for your help!![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

Anyone seen any code or libs for automating Excel wihout using MFC?
I was hoping to use #import, but its a mess, and would rather not have to do everything that hard way as there is quite a bit to do.
I'm trying to avoid VB if I can.

Yes, see this MSDN article HOWTO: Automate Excel From C++ Without Using MFC or #import[^]

Thanks. I think I've seen this one. I was looking for something along the lines of #import to easy make use of smart pointers, but there are loads of clashes in the namespace (renaming seems to have no effect), and then a problem with reference counting.

Ah Ah! And you say smart pointers is a mess.
Better think twice. Smart pointers allow to focus on applogic, not on horrible COM details.

I wanted to use smart pointers, but there is a problem with reference counting.
Microsoft recommend using MFC, directly then lastly #import for Excel and other office apps, becuause they have done something funny.
Its not just a case of #import for e.g. ADO, where you only have to rename EOF. With Excel it seems there are over a hundred clashes in the namespace.
Have you had any luck with #import and Excel, if so I would be grateful for any tips.

There is no direct Office support in the MFC classes.

In the unlikely case you have this problem, you may just end your troubles by using the namespace rename attribute in #import.

Using smart pointers to drive Office apps is much like doing it with VB. Code is just easy to work with : in addition, you have intellisense!
The only tip about it, but it's a general tip about using smart pointers, is to avoid at all cost to use smart pointer instances in class members. Smart pointers are almost by design meant to be used as local proc variables.

I know, but using the class wizard to import the type library takes about 30 seconds, and makes life very easy.

Yep, tried that, but it was having none of it.

Have you got a quick example? When I used namspace rename with #import it did not seem to work.

Never knew that. I've used parts of ADO happily as members of a class, well certain parts of it like the ADODB.Connection and Recordset, but not others, that are managed by a parent object e.g. Field, that could go out of scope if you moved to the next record.
As I said if you had a quick snippet of code with #import for Excel I would be really grateful.
Thanks,
Giles

This *is* #import, it has nothing to do with MFC. (remember #import is not C++ standard, only proprietary MS stuff).

Always look up samples in the MSDEV CD. You've got ComExcel for instance. And it works like this :
#import "C:\Program Files\Microsoft Office\Office\excel8.olb" auto_search auto_rename

Thanks, this worked. I was still getting errors withe the rename_namspace() attribute.

is there a way to tell the date modified of a file on the web through an http request? i dont want to do ftp requests..
still a newb.. cut me some slack :P

I am sure there is probably a way to get that information, I am not sure how to get it though.
However, if you want the date in order to know whether you should download the file or not, you can add the If-modified-since header item, and then the server will only send the file to you if it has been modified since the date that you sent. If the server does not send you back a file then the return status code will be 304.
If you are using MFC here is the sample code that you would use with the CTime object. If you would like sample code for regular C/C++ let me know.
CString sFileDate;
sFileDate.Format("If-modified-since: %s\r\n", ctime.FormatGmt("%a, %d %b %Y %H:%M:%S GMT"));
Good Luck

how would i use this if-modified-since when requesting the file? currently i am just giving the location of the file on the web, and where i want to save it.. here is what i have, thanks!
hr = URLDownloadToFile( NULL,
sURL,
sFile,
0,
&callback
);

Hello...
I need to show an editcontrol and a combobox over a listcontrol depending of the kind of edition that is allowed in the field that I want to modify...
(i.e: if I'm editing a field that can only have 3 possible values, the combo have to be shown, but if the field can get any value, then I need to show the editbox)
In order to do this I'm using an article readen in codeproject
http://www.codeproject.com/listctrl/editing_subitems_in_listcontrol.asp[^]
and my problem is that when I do the same that is explained in this article, I don't understand why the editcontrol and the combobox disappear...
I don't want the combo box to disappear, the editbox is OK...
any idea?
NOTE:
I've tried to set it topmost (using SetWindowPos), but it's the same...
As always thank you in advance...

My guess would be that you need to change the tab order of the edit/combo controls compared to the list control. They either have to be before or after it in the tab order. I forget which.

I hate when the solution is so simple...
I've invalidated the combobox...
but thank you for your interest!

OK guys...I'm trying to display an AVI file on my dialog with a transparent background and I'm not having any luck,
I made an AVI file with a white background on each clip. I have an animation control on my dialog and I have both transparent properties set. When I go to play the AVI, I still see the white background.
Here is the function to create the control:
HWND CreateAnimationCtrl(HWND hwndDlg, int nIDCtl)
{
HWND hwndAnim = NULL;
RECT rc;
POINT pt;
hwndAnim = Animate_Create(hwndDlg, IDC_ANIMATE, WS_CHILD, ghInst);
Animate_Open(hwndAnim, MAKEINTRESOURCE(IDR_AVI));
ShowWindow(hwndAnim, SW_SHOW);
return hwndAnim;
}
Here is what I call in the WM_INITDIALOG routine:
hAnim = CreateAnimationCtrl(hDlg, IDC_ANIMATE);
Animate_Play(hAnim, 0, -1, -1);
Do I have to do something special to the AVI as well?
Any help would be greatly appreciated.
