I hate to reply to my own posts, but for anyone interested..
I found some more details on SendARP() and why it's
not very usable.
- Not supported on Win9x/ME/NT.
- Doesn't add the result to the global ARP-cache.
- Doesn't retransmit on timeout.
So I probably end up writing my on ARP resolver.

Export your class as Gallery, then make new ActiveX project and import your gallery!

For every member function, add a method. and for every public member variable add a property (Get/Set functions).

I work for a small programming house, that has just doubled in size( now FOUR Programmers!!!  ), we now need to implement some sort of source control and bug tracking programs. I have had a quick look at cvs for source control, but i haven't been able to find and decent bug traking programs. I'm just wondering what other people out there are using, and if any one has had major issues implementing or using cvs, or is there is something else that is a bit better.

Do you have SourceSafe?

Just set up cvs on local drive here. (TortoiseCVS and WinCVS-- using the TortoiseCVS mostly.) It works like a charm.

I've having all kinds of memory corruption with _bstr_t. I was also told that _bstr_t was the devil and never use it, even if my life depended on it  So I made this useful function to load strings
_bstr_t LoadStringEx(HMODULE hModule, int ID)
{
CComBSTR bstrTemp;
bstrTemp.LoadString( hModule, ID );
_bstr_t strT( bstrTemp.m_str, FALSE );
return strT;
}
I could use the LoadString function from CComBSTR and CStringT directly too...
Thanks!

_bstr_t has it's problems, but is not THAT bad that I would avoid using it. CComBSTR is better, but does not provide the functionality that _bstr_t does. Why not write your own BSTR wrapper ?

Hi,
In the near future I'm going to have to extract some text from PDF documents, as well as search the text in them. Can anyone recommend a good library? It would be good if it was cross-platform and didn't have redistribution costs.
Thanks,
Stuart

There's some good stuff on SourceForge. Do you need to work with PDF's that are compressed ? I don't think it would be too hard to write the code to decompress them anyhow, and then it's just cleartext, easy to search for.

A technique I have found useful for PDF document that have copy protection turned on (so you cannot just cut&paste the text or such like) is to do the following:
Add a dedicated-purpose printer, Name=PSPrinter, based on some good Postscript printer (say, HP LaserJet 5000 Series PS). Set the port to FILE.
Then print the PDF to a postscript file using AcroRd32.exe like:
AcroRd32.exe /n /t file.pdf PSPrinter "HP LaserJet 5000 Series PS" file.ps
(use full pathnames for everything here)
The resulting file.ps is easily parsed for text or (if it is well-behaved) passed to GhostView which allows for search and extract of text.
Note: you cannot just print to a "Generic/Text" printer as AcroRd32.exe will often refuse to print to a printer that cannot make an exact copy (for this very reason, I suspect).
Good luck!

I loaded records from a database and would like to set the first row in a list (CListCtrl) selected to match the first record in the dataset. For example, SetCurSel(n) in CComboBox selects the row.

HWND FindWindow(LPCTSTR lpszClassName, LPCTSTR lpszWindowName)
I know I can use NULL as the first parameter but just curious, given all source code of a project, how do you know the "class name" of a CWnd? Also, is there any way to change the "class name"? Thank you.
|
|
|
|

That depends. For instance, controls usually have very specific window classes, for instance buttons are "BUTTON", so if you want to find all the edit controls with a specific bit of text, you use FindWindow("EDIT", "TEXT").
For more generic windows, and MFC, you can use Spy++ to find the window class if you like.

Where are we going? And why am I in this handbasket?

The easiest way is by spying on the window (Spy++).
Bin wrote:

The framework assigns a default class name to CWnd-derived objects. I believe the easiest way to change it is by overriding the PreCreateWindow method.

I tried to override CMainFrm's PreCreateWindow method and set "cs.lpszClass = _T("my test window");" but then got "Failed to create empty document" error message. What else has to be done? Thank you.

I think it's important to register your own window class before assigning it's name to lpszclass. Thus first call RegisterClassEx, providing a WNDCLASSEX structure containing your class name. The most values of WNDCLASS struct can be filled by calling GetClassInfo.
WNDCLASS wndcls;
memset(&wndcls, 0, sizeof(WNDCLASS));
::GetClassInfo(AfxGetInstanceHandle(),"AfxFrameOrView",&wndcls);
wndcls.lpszClassName = "MyNewClass";
::RegisterClass(&wndcls);
After that steps your class name is made known by the system and can be used.
