only way I know is:
CWnd * pDesktop = GetDesktopWindow();
CDC * pDC = pDesktop->GetWindowDC();
...
//Mess around with DC
...
pDesktop->ReleaseDC(pDC);
I suppose you could create a copy in memory before BitBlt'ing it back? I'm sure someone else on here has a *much* better way....

How to get path to application execuable file???
Please send me solution on my email;
piopawlu@interia.pl;
|
|
|
|
|
I just get the value stored in
CWinApp::m_pszHelpFilePath
and do a CString::Replace(".HLP", ".EXE");
e.g
in CWinApp::InitInstance(...)
...
CString strPathExe = m_pszHelpFilePath;
strPathExe.Replace(".HLP", ".EXE");
...
It can't be the best way, but it's always worked for me.

Does anyone know of any "AOL like Instant Messenger" software that I could integrate into a custom designed application. It doesn't need to work with AOL (or any other proprietary type system). I would just like to give my users the ability to quickly send messages to other users that are logged on. Maybe a simple ICQ chat would do? Any suggestions?

I seem to remember someone posting a socket-based IM program either here or on CodeGuru.
AlsI think there are a number of OpenSource IM programs, although I don't know which to recommend. Sorry!

Does anyone know of a revision control system that I could easily integrate into a custom designed application? My users need to be able to check in/out text files and view past revisions. I would like to be able to setup a document server and then add simple menu button to my application to give my users access to the files. All of the revision control systems that I have seen are either a) standalone systems without any integration, b) expensive when you need a site license, or c) bloated with features that my users don't need. Can anyone offer any suggestions?
|
|
|
|
|
Yes, you can use GNU RCS, which comes with source code. However, since it's GPL'd you'll also have to release your source with it.
The other things you can do is simply use RCS standalone executables and just call them from within your program.

Does anyone have a free line drawing control that can be used in VC6 like the one in VB6? I want to visually
draw lines on a dialog box or CFormView-derived view. The hard way is to implement the OnDraw() event handler,
but doing it visually at design time would be terrific.
|
|
|
|
|
If I've ever needed to draw a line, I've always done a really thin control.

I'm trying to write a program that will allow reliable transfer of files between computers on a network. It would be very useful if I could list all the uses user names on a network as network Neighborhood does.
Is there a way to do this?
Thank you for any help

How do I print the GIF file from a VC++ application
|
|
|
|
|
Do you know what the GIF is ? I assume not, in which case you'll need to either
a/ forget it or
b/ pay UNISYS a swag of money.
GIF uses LZW compression, and even if your program doesn't make money, you need to pay them if you support GIF. That's why a lot of graphics software ( mine included ) does not support GIF. Assuming you chose GIF at random, the answer for any other format is you need first to read it in, which entails using a library like paintlib ( www.paintlib.de ), then it's merely a case of stretching it onto a print DC. I say stretch because printers measure size in TWIPs and a screen shot in pixels equates to enough TWIPs to make a small postage stamp.
If you're using Doc/View most of the work is done for you, if not, there are classes on this page that will give you everything you need.
|
|
|
|
|
don't!
if your app reads GIF files, you have to get a license from the Unisys corporation. this applies even if you use an external appliation (like IE) to read and render the image.
use a different format, if possible.

I would like to create a dialog window from a win32 console program, but i dont know how to go about doing
this. Anyone know how? I created the CALLBACK procedure, and the resource template, but when i go to call
CreateDialog(), i do know what to pass in for the current instance, and the parent window, and NULL does
not work (it will compile, but it won't create the window).

Hi Dave
I think what is missing is
ShowWindow(SW_SHOW);
NULL as a parent works fine, I tested it
CTestDlg::CTestDlg(CWnd* pParent)
: CDialog(CTestDlg::IDD, pParent)
{
Create(CTestDlg::IDD, pParent);
ShowWindow(SW_SHOW);
}

I have a memory address stored in a variable (gotten from a stackwalk), like so
int address = 0x00FE3D; // an arbitary address
How can I check whether my process has access to that address??.
PS. I was looking at IsBadReadPtr() but it requires a pointer to memory block. How can I get a pointer that points to the value specified in a variable?
|
|
|
|
|
Just pass a block size of 1:
void* pv = (void*) 0xfe3d; <br />
bool bCanRead = !IsBadReadPtr ( pv, 1 );

Is there any function, etc, available to search through all the items in a tree ctrl by name?
E.g. I populate a tree ctrl, then need to go back and add a new item 'D' as a child of item 'C':
ROOT
|-A
| |-B
| |-C
| |-E
|-F
|-G
Becomes:
ROOT
|-A
| |-B
| |-C
| | |-D
| |-E
|-F
|-G
How can I find and return the HTREEITEM pointer to 'C'?
Thanks for any help,
David Wulff

I am having problems building a 2 dimensional dynamic array. I built a one dimensional dynamic array, but I don't know were to start with a 2 dimensional.
I cannot find any helpful documentation on it so far on it. Any comments?

int nRows = 6;
int nCols = 3;
int ** cp;
// Allocate rows
cp = new int *[ nRows ];
// Now allocate using a loop
for ( int index = 0; index < nRows; index++ )
{
cp[index] = new int [ nCols ];
}
cp[5][0] = 1;
cp[5][1] = 2;

Hi!
I am writing a debugger. In my Watch-View (which is basically a ListView) I have to check the user input of new variable values for validity (eg. a variable of type int must not be assigned the string "qwerty"). I do this now
by checking the validity when the editing has already ended (using a LVN_ENDLABELEDIT handler). If it is not valid, I do not set the value.
What I WANT to do, is to prevent the user from ENDING editing, unless he has entered a valid value or he cancels editing.
Any hint would be appriciated,
Hamader Peter

From MSDN:
"If the pszText member of the LVITEM structure is non-NULL, return TRUE to set the item's label to the edited text. Return FALSE
to reject the edited text and revert to the original label. "
(See MSDN Online)
Cheers,
Paolo.
