If the resource is managed by a C++ class you can put a critical section in the class and lock it whenever any code needs exclusive access to the resource. Of course you also need to ensure you can't get into a deadlock situation.

Hi,
Can anyone answer the following question or at least tell me where I can find the answer ?
When you install VB, Visual studio, Ms word etc... and you have a PC with multiple registries (say one for stand-alone use/login and one for network use/login) the software manages to register itself in all the registries and you can use it whichever way you log in. With my own software it will register OK but the settings I enter into the registry are only visible in the registry active at the time of registration. When you log in differently and another registry is used the program cannot access the values in the original one.
The solution seems simple: register the software in all possible registries as the Microsoft products seem to do. The question is: how do you do that ?
Any answers most welcome and appreciated.

one thing you can consider is to add your registry entries to HKEY_LOCAL_MACHINE, instead of HKEY_CURRENT_USER. the first is readable to most processes, regardless of user login. the second is unique for each user.

Are you confusing HKLM (Local Machine) and HKCU (Current User)?
You need administrative rights to write into HKLM but it is visible to all users.

Thank you for the help. A case of "glaringly obvious once pointed out". It ought to make all the difference.

I'm using doxygen for the first time and I'm trying to configure the configuration file with the doxywizard. When I run the generation I've got "unknown command or file name" dos window and that's all.
How can I figure out what's wrong with my configuration file this way ?
I'm using the latest 1.3.

Thanks a lot Andreas, I did a search in the articles before asking but I don't know why I missed this.
My main problem comes with the wizard, I think the files included in the zip file will greatly help me solve this.
Thank again

I'd like to use a "output iterator" as a function parameter, but somehow I fail to do that. Any hints where to read about this?

You can do somethig like that:
<br />
FILE* m_pFile1;<br />
FILE* m_pFile2;<br />
<br />
m_pFile1 = fopen("a.txt","r");
m_pFile2 = fopen("b.txt","a");
<br />
char Dummy;<br />
while (!feof(m_pFile1))<br />
{<br />
Dummy = fgetc(m_pFile1);<br />
fputc(Dummy,m_pFile2);<br />
}<br />

Don't be rediculous,
fgetc & fputc? Reading & writing file by character....
LPTSTR lpBuf;
DWORD dwRead, numChars;
HANDLE hFile = CreateFile(fileNameA, GENERIC_READ,0,0,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,0);
if ( hFile != INVALID_HANDLE_VALUE)
{
numChars = GetFileSize(hFile,0);
if ( numChars )
{
lpBuf = new char[numChars+1]
::ReadFile(hFile, lpBuf, numChars +1, &dwRead, NULL);
HANDLE hFileB = CreateFile(fileNameB, GENERIC_WRITE,0,0,OPEN_ALWAYS,FILE_ATTRIBUTE_NORMAL,0);
if ( hFileB != INVALID_HANDLE_VALUE)
{
::SetFilePointer(0, 0, FILE_END);
::WriteFile(hFileB, lpBuf, numChars, &dwRead, NULL);
CloseHandle(hFileB);
}
CloseHandle(hFile);
}
}

Oh , the spelling mistake. the lastest should be "latest"
The focus is: I want appending the "latest" datas of aa.txt to the file bb.txt
The latest datas in the file aa.txt are the datas that are not included in the file bb.txt.
Note: i only want to append the datas that the bb.txt is not included.
Thanks!

i have placed a CRichEditCtrl in a View.Size of that Control is exactly same as that of the View.No Vertical & Horizontal scrollbars for that CRichEditCtrl. AutoScrolling also disabled.using lfHeight of LOGFONT i set the hieght & using SetFont, i have set it to that Ctrl.now i know the Font height & height of the CRichEditCtrl.(GetClientRect())
With this information how can i calculate maximum number of lines that could be displayed in that Ctrl without scrolling?.
I assumed,
MaxNumberOfLines=(Height of the CRichEditCtrl)/ FontHeight.
but it is not exactly correct.i think there i am missing the vertical space b/w 2 lines.

If you are using a single font in your rich text document then you should be able to select the font into a display compatibler DC (possibly tempory) then use FontHeight = GetTextExtent().cy to determine the maximum FontHeight of a line of text. The string passed to GetTextExtent() can be either the entire text you with to display or a subset like "iWy", the subset would have to contain tallest (W,H,$) and lowest hanging (y,g,p) charactes that you expect to use.
I have written some text editors, including color coded, and this basicaly how I determine the height of all text lines.
Trust in the code Luke. Yea right!
