Vertical.

Here is the code I use to inser the items.

<br />
//<br />
	// Add the item to the list view.<br />
	//<br />
    LV_ITEM lvi;<br />
    lvi.mask = LVIF_TEXT | LVIF_IMAGE | LVIF_PARAM; <br />
    lvi.iItem = index; <br />
    lvi.iSubItem = 0; <br />
    lvi.iImage = image;<br />
    lvi.pszText = LPSTR_TEXTCALLBACK; <br />
    lvi.lParam = (LPARAM) pItem; //pItem has some data<br />
<br />
    if (m_ctl_files_list.InsertItem (&lvi) == -1)<br />
        return 0;

Any way to force the scroll bar to show up ?

Windows XP Theme Colour Scheme

26-Aug-04 3:17

I've not ever seen this type of behavior before. By default, a list control's scroll bar will show up as soon as an item is added that is at or near the bottom of the control. Using Spy++, can you tell me what styles that control has?

What error are you getting?

Did you call CoInitialize() before the CoCreateInstance?

Without knowing the error (post the return value from CoCreateInstance()) I can only guess, but the first parameter looks like an IID, not a CLSID. You need to put the CLSID of the WMP object there.

...ok I fixed the classid thing like this:

<br />
CLSID idMediaPlayer;<br />
HRESULT hr = ::CLSIDFromProgID (L"WMPlayer.OCX.1", &idMediaPlayer);<br />

Well I was using windows media player 8 but I found that I jammed up the class-id... then I installed Windows Media Player 9...
The error code is: "REGDB_E_CLASSNOTREG" ...
I am not sure if I have to use "msdxm.ocx" for windows media player 9...

Well... I am a beginner ...

dll in Visual C++

25-Aug-04 3:36

Hy everyone!

My colleage wants to include a "foreign" dll in his C++ program (written in VC++ 6.0). He said he has added the path to the dll in the settings of VC++ 6.0.

In command he is able to run the executable when the dll is located in the same folder. But in VC++ it does not work throwing an error message telling the dll is not available.

What is he doing wrong because at the moment I cannot find out, because I did never work with version VC++ 6.0 (I did only work with Visual Studio 2003 and that's a little different).

So if someone of you could tell me what he has to do to make VC++ find the dll please let me know and I will forward the infos to him.

Thanks!
Stephan.

He can add his path to the Global PATH enviroment variable, or he can drop his dll in the project directory, cos this is the default directory when a program is launched from the IDE

Scaling ellipses using XForm in Win98 SE

Franz Liste25-Aug-04 2:24

Hi everyone

As the message is quoting, I am looking forward to scale some graphics using XFORM in Windows 98 Second Edition.
Also, it's important to mention that although some sites state that Win98 doesn't support scaling, the Platform SDK's says as follows regarding ExtCreateRegion:
"Windows 95/98/Me: World transforms that involve either shearing or rotations are not supported. ExtCreateRegion fails if the transformation matrix is anything other than a scaling or translation of the region."
Since scaling is what I'm trying to do, I should have no problem doing so as far as Microsoft's is concerned. I did found some MFC stuff that was handling Win98's scaling through XFORM, but I have to stick with Win32.
So a little recap on what I need: scaling graphics from a window using XFORM, needs to works in Win98 and STRICTLY in C/Win32 or C++/Win32.

Regards,

Franz Smile | :)

Can't find file name.

I'm using visual C++.net 2002. I created a simple MDI through MFC project. What I'm trying to do is Open a file view it and then click on a control to send the file to a specific location already defined. The problem is where does The Opened file name get stored.

The code looks something like this.

 <br />
BEGIN_MESSAGE_MAP(CARMFirstBuildApp, CWinApp)<br />
	ON_COMMAND(ID_APP_ABOUT, OnAppAbout)<br />
	// Standard file based document commands<br />
	ON_COMMAND(ID_FILE_OPEN, CWinApp::OnFileOpen)<br />
	<br />
	// Standard print setup command<br />
	ON_COMMAND(ID_FILE_PRINT_SETUP, CWinApp::OnFilePrintSetup)<br />
END_MESSAGE_MAP()<br />

ID_FILE_OPEN is the menu option to open a file. I understand when I click on Open in the menu it brings up a dialog box to select a file then click okay to open that file. How can I find the file name that was selected. I've tried everything I could think of. Being new to Visual C++.net is not helping much.
Any Help would be great thanks.

The name of the file is stored in the CDocument-derived object.

Hi
I am using the following code to get the desktop contents:
if (SUCCEEDED(SHGetDesktopFolder(&lpDesktopFolder)))
{
//strpath: has the desktop folder path.

MultiByteToWideChar(CP_ACP, MB_PRECOMPOSED, (LPCTSTR)((strPath != "\\MyComputer")?strPath:""), -1,
olePath, MAX_PATH);

hr = lpDesktopFolder->ParseDisplayName(NULL,
NULL,
olePath,
&chEaten,
&pidl,
&dwAttributes);
if(hr != S_OK)
{
lpDesktopFolder->Release();
return;
}
hr = lpDesktopFolder->BindToObject(pidl, 0, IID_IShellFolder, (LPVOID *)&lpShellFolder);

If I use this code I can't find *My Computer* and icons. But if I use
SHGetDesktopFolder(&lpShellFolder)
I can see the *My computer* in the list.

Could any one please tell me where I am going wrong?

Regards
Neha
