I work for a small programming house, that has just doubled in size( now FOUR Programmers!!! Big Grin | :-D

), 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.

Have a look a FreeVCS http://www.freevcs.de/index.htm[^] I use the VCS part, but haven't tried its Bug Tracking as I handle this on another way.

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

I hadn't heard of this before but a quick search of MSDN shows:
"Windows Sockets 2.0: Write Scalable Winsock Apps Using Completion Ports"
http://msdn.microsoft.com/msdnmag/issues/1000/Winsock/default.aspx[^]
and
"Pop3 Sample: POP3 Sample"
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vcsample98/html/vcsmppop3sample.asp[^]
which may or may not help.;)

If you do find some interesting example code I'd be interested to hear.

Help me get rid of _bstr_t !!!

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 Wink | ;)

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 ?

PDF text extraction

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!

How can I set a row selected in a CListCtrl control?

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.

How do you get "lpszClassName"?

Abin4-Feb-03 13:05

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.

Re: How do you get "lpszClassName"?

Erik Funkenbusch4-Feb-03 14:16

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.

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 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;

// Start with NULL defaults.
memset(&wndcls, 0, sizeof(WNDCLASS));

// Retrieve WNDCLASS structure for default window class.
::GetClassInfo(AfxGetInstanceHandle(),"AfxFrameOrView",&wndcls);

// Give new class a unique name.
wndcls.lpszClassName = "MyNewClass";

// Register new class and return result from ::RegisterClass().
::RegisterClass(&wndcls);

After that steps your class name is made known by the system and can be used.

What is CImage ? Is that the Image class in GDI+ ? Just create a Graphics object to contain the dialogs HDC and draw the image onto it.

ON_WM_KEYDOWN() question

4-Feb-03 11:56

hi,

by default using a tree control, if i don't declare on_wm_keydown() in my message map, the treectrl uses its own predefinied actions for the keydown operatiosn.. is it possible to use the predefined keydown operation with the ones that i implemented myself at the same time? ie, if keydown message is vk_up and vk_down, i want to use the default treectrl operation(moving the focus of a node in the tree up and down). if keydown message is vk_insert, i want to use my own function.. is it possible? thanx in advance..

Re: ON_WM_KEYDOWN() question

Alvaro Mendez4-Feb-03 14:54

Alvaro Mendez

Yes! Simply check for VK_INSERT. If it happens, do your stuff; otherwise, call the base class's OnKeyDown.
