I have a small problem with bolding text using RichEditView. I have tried using this code:

CRichEditCtrl &RichCtrl = GetRichEditCtrl();
CHARFORMAT cf;
cf.dwEffects = CFE_BOLD;
cf.dwMask = CFM_BOLD;
RichCtrl.SetSelectionCharFormat(cf);

I have used the same code for underline, italic, strikeout and link (changing the attributes to match the type) and the code works for them.

Any ideas?

CStatic/PreSubclassWindow/WS_VSCROLL

Hi,

i am trying to get a CWnd derived class having a vertical scrollbar by PreSubclassWindow.

void CWndDerivedClass::PreSubclassWindow()<br />
{<br />
  ModifyStyle( 0L, WS_VSCROLL );<br />
  CWnd::PreSubclassWindow();<br />
}

It's not working, all i can see is a vertical scrollbar but i can't use it. Confused | :confused:

Spy++ing: There are only WM_NCHITTEST messages with return value HTTRANSPARENT (no HTVSCROLL).

If i CreateEx the class:

<br />
m_cWndDerivedClass.CreateEx( 0L, NULL, NULL, WS_CHILD|WS_VISIBLE|WS_VSCROLL, rcRect, this, 1002 );<br />

then i have a valid and full functional vertical scrollbar!

Does anybody know how to solve this problem?

I don't want to CreateEx the derived class, or do i have to?

thx a lot

Friends,
I want to enumerate files present in certain folder. I may also want to enumerate files present in a subfolder withing a folder.
What are the possible methods to do so ?? I would prefer some non MFC solution.

You must call FindNextFile() before you use the values in the WIN32_FIND_DATA structure:

HANDLE find;
WIN32_FIND_DATA wfd;

find = FindFirstFile( "path\\to\\your\\folder\\*.*", &wfd );

if( INVALID_HANDLE_VALUE != find )
{

    while( FindNextFile( find, &wfd ) )
    {

        // wfd will contain the data of the current file

    }

    FindClose( find );

}

P.S. The convention on Code Project is to enclose blocks of code in <pre>...</pre> tags.

make sure you read the description of the second paramter on FindFirstFile and the remarks Poke tongue | ;-P

Hey! Look at this nice litte example which happens to use the data in the WIN32_FIND_DATA structure before FindNextFile is called

Oops. It looks like you're right Blush | :O

Although, it doesn't really make a difference, in this specific case, since FindFirstFile() for *.* will return the current directory (named ".").

Titleless dialog

Hi all:
I have a titleless dialog(for some reason), which has a constructor like
MyDlg(CWnd* pParent = NULL);
But somehow I want to add a button to this dialog which have the standardize minimize funtion.
here is the customized minimize funtion's implementation

<br />
void MyDlg::OnBtnMinimize()<br />
{<br />
	ShowWindow(SW_MINIMIZE);<br />
}<br />

But after I clicked the minimized button it just disappears. Later I found it(just part of this dialog) positioned at somewhere in the lower left corner of the desktop and just above the system taskbar. It obviously not positioned at the system taskbar.

How can I get the standard minimize function without the title bar? Do I have to pass the return value from GetDesktopWindow to Mydialog dialog, I tried It didn't work!

A window without the WS_CAPTION style gets treated differently, as you've seen. Add the WS_EX_APPWINDOW extended style and it should behave like you want.

Thanks for your WS_EX_APPWINDOW answer, it works.But if you don't mind I wanna ask you few more questions which related to this one.

When I clicked the minimize button, this dialog does positioned at the sys taskbar. But what makes it not so good is it doesn't have caption when It appears in the sys taskbar. I've tried to add CAPTION "" to the script and it worked but it at the expense of just the part of dialog appears not as whole.How can I get a caption at the taskbar(still does't have caption bar) when It minimized or maximized?

Furthermore, When I click the dialog at the sys taskbar consecutively, It seems not responding well, it only get minimized. Which should be get maximized and minimized correspondingly.

Thanks fot your time and patience!

Meaning of error code: 800a0030?

I have been trying to debug my Add-In for Visual Studio .NET 2003 on Windows XP SP2. I seem to be always getting an error message with the error code 800a0030. I have tried using Error Lookup but even that can't tell me what the code means, it just says error message not found. I have also looked through all the files that come with VS .NET 2003 to see if I can find it there but no luck. Cry | :((

Does anybody know?

The file WinError.h has a table at the beginning that explains the what the bits in the error code are used for. The copy I have here (VS 2002) does not have a definition for error 48 (0x0030) but maybe yours does. Also, depending on what technology you are using, error code 48 could be defined in some other file.
But then again, it could just be a custom error that is not defined anywhere Sigh | :sigh:

Well according to google[^], the error seems to be 'Error loading DLL'

Does your error message give any more information, like the name of the DLL. At a guess, Visual Studio doesn't like something in your add-in; maybe a missing interface or a problem in the DLL initialization code.

No I just get the error code. It seems like the error occurs when I make use of the VCCodeModel functions. Cry | :((

. I can't even step into the function (the exact name I can't remember at the moment, I think it has to do with getting a project from a collection of projects)

Trouble with List Control and Dialog

Archer28230-Dec-04 19:03

30-Dec-04 19:03

Ok, i have a dialog which i made with the resource editor. all the code is done with pure win32, no MFC.

Now when i have list control on the dialog, the CreateDialog function fails and the dialog is not created. When i set the "No Fail Create" (or something like that) prop on the dialog, the function succeeds the window is made but the list control doesnt show up.

when i take the list control off, it doesnt matter whether the "no fail create" prop is set or not, the function succeeds and everything works fine.

i also have the same problem when i add a progress bar.

extra info:
a while back, i made a MFC project that used a list control and a progress bar, the list control caused no problem, but when the progress bar was put on the dialog, the program crashed.

Michael Dunn30-Dec-04 19:22

The dialog creation is failing because the list control window class isn't registered. Add a call to InitCommonControls() in your app's init code.
