Aside from the site containing lots of broken links, some of which take you to adult-related sites, I saw nothing about producing high-level code as a result of reverse-engineering an EXE or DLL. This might have been a better choice.

Right, ny intention was to provide a starting point for reverse engineering, and since i've seen Mammon's capable contribution to rev eng, it would be a good place to start learning about it.
Wasnt intending to supply a "decompile to C source code" site.

Hello,
This is the second (and last) time I (try) to approach this issue -- I'm posting a second time because I don't quite understand ScrollDC's mechanics, so please forgive for the (almost) duplicated post.
Righ then, I have this (custom) control which outputs text within a RECT viewport and, at some point in time, there is the need to scroll its contents (either down or up -- always vertically though).
The problem I keep getting is that whenever a window hovers the control, the DC does not scroll the contents properly. Lets imagine the following situation:
My custom control's pos/size: [0,0] - [100, 200] // [x0,y0] - [width,height]
Now imagine a window, say a dialog box, hovering at [75, 60] - [500, 350]
My custom control's DC does not scroll from [75,0] - [100,60] , I keep getting "garbage" on that location
I know I'm doing something wrong here, but I just don't know what.
This is the call I'm doing to the ScrollDC:
DCHandle -> ScrollDC(0, iYScroll, &ViewArea, &ViewArea, NULL, NULL);
iYScroll represents the amount of pixels to scroll up/down
ViewArea is basically the viewport area
Any comments and/or suggestions are welcome.
Thank you for taking the time,
David

Would you be willing to send me your code so I can look at it? I don't really have time to pull together something which has this scenario and I don't think I can answer your question off the top of my head.
Of course, MSDN doesn't say anything about this situation in ScrollDC, but I did find this comment:
[MSDN]
An application should use the ScrollWindow member function of class CWnd when it is necessary to scroll the entire client area of a window. Otherwise, it should use ScrollDC.
[/MSDN]
ScrollWindow's description in MSDN: "CWnd::ScrollWindow: Scrolls the contents of the client area of the current CWnd object."
ScrollDC's description in MSDN: "CDC::ScrollDC: Scrolls a rectangle of bits horizontally and vertically."
It may be that ScrollDC simply isn't suited for what you are doing, since you probably want the whole client area of your custom control to be scrolled. I'm not sure if using the other function will solve the problem. Give it a try and if it doesn't work I would be willing to look through your code if you would be willing to send it (Alexander@wisemanweb.com).
Sincerely,
Alexander Wiseman

To Hello,
Created dynamically an 2-D array CButtons in the CFormView.
How do you add the message handler?
Thanks.

Use this macro to map a contiguous range of control IDs to a single message handler function for a specified Windows notification message, such as BN_CLICKED.
ON_CONTROL_RANGE(wNotifyCode, id1, id2, memberFxn )

Hi guys,
On closing my app I got a list of memory leaks in the output window. No problem, I went through the list, double-clicking the code line reference and adding a "delete" for that object. However, I'm left with 1 single frustrating little bugger that doesn't have a code line reference at all:
Detected memory leaks!
Dumping objects ->
{562} normal block at 0x0032D488, 4 bytes long.
Data: < s2 > 10 73 32 00
Object dump complete.
Why does this one not have a code line reference and how do I go about finding it?
Many thanks,
Simon

Take a look at the _CrtSetBreakAlloc in the MSDN. You can assign this your allocation number (562). So if you run your software the exact same way, you should get a BP when that allocation takes place in your program. You can then use the stack trace to backtrack to the offending code.
If you vote me down, my score will only get lower
|
|
|
|
|
Hi Roger,
Thanks for the reply - this looks exactly what I'm looking for. The only thing is that my allocation number isn't the same every time, even when I run the app in exactly the same way. It shifts between 510 and 520 with the occasional 550 thrown in for good measure! Is there a way around that?
Thanks again for your help,
Simon

Hi,
i have an mc file containing text in english and korean languages.I have changed my System Locale to Korean and my OS is Windows 2000(English).When i compiled this mc file i am getting all the string ids in .h file.So i was not able to access these ids using FindResourceEx() as it is searching the string table for the ids and my other language id is in .h file.How can i make this fucntion to search in .h file also?Or Is there any other way where i can copy the string ids to string table
Plz help me

Dear Experts,
I am a novice student programmer who is touching Embedded Visual C++ for the first time in my life. (Previously only learnt BASIC and Visual Basic).
Currently, I am involved in this project to this simple pda to pda wireless communication. I am currently stuck at the server side of the communication program. (The client program has been written and tested to be working well).
The problem with the server side is that the program does not seems to execute the OnAccept function of the Listening socket(
although it jolly well could create a socket, listen for connection and seems to make the client program aware of its presence
by enable the client able to establish connection with the server whenever the client is attempting to connect the same port
that the socket is listening to). By not doing so, I am unable to create another client socket for communication. (Came to this
conclusion as neither results I have put in the function has appear when excuted)
I have declared the following Classes:
CServerApp (By default generated)
CServerDlg (By default generated)
CListenSocket (Class for the listening scoket. Base class: CSocket)
CLinkSocket (Class for the Client scoket. Base class: CSocket)
Member Variables (Only for the class CServerDlg, the rest does not have any)
IDC_cmdListen
Function: Listen for connection
Type: CButton
Member: m_bListen
IDC_cmdDisConnect
Function: Disconnect current connection
Type: CButton
Member: m_bDisconnect
IDC_cmdStop
Function: Stop all server service
Type: CButton
Member: m_bStop
IDC_Port
Function: hold the value of the port name
Type: int
Member: m_sPort
IDC_Status
Function: hold the value of the text meant for a status screen
Type: CString
Member: m_sStatus

How can develop (using c++) the multiple clipboard Like Word...?
Thanks
Multiple Clipboard
|
|
|
|

Maybe you can save the content of clipboard into variable every time the clipboard is accessed
<italic>Work hard and a bit of luck is the key to success.

If you're using VC++ 7.x the IDE already has this feature. Use Ctrl+Shift+V to cycle though and paste the items. If you're using VC++ 6 there's a macro that does it. It's either here at codeproject or at codeguru. It looks like this...
' Three simple macros to implement a secondary clipboard
' Global to act as clipboard
Dim gSecondClipBoard
gSecondClipBoard = ""
Sub SecondaryClipBoardCut()
'DESCRIPTION: Performs a cut of current selection to a secondary clipboard.
gSecondClipBoard = ActiveDocument.Selection.Text
ActiveDocument.Selection.Text = ""
End Sub
Sub SecondaryClipBoardCopy()
'DESCRIPTION: Performs a copy of current selection to a secondary clipboard.
gSecondClipBoard = ActiveDocument.Selection
End Sub
Sub SecondaryClipBoardPaste()
'DESCRIPTION: Performs a paste of secondary clipboard to the current selection.
ActiveDocument.Selection = gSecondClipBoard
End Sub
