I have downloaded a project that contains several cpp, sln, vcproj, and corresponding *.h files.
Could not open the vcproj or sln file.
I am using VC++6. How do I know which is the main cpp file? What file should I open via the IDE?
thanX

Try using this tool :
VC++7 to VC++6 project converter[^] to convert and then try to open with vc6.

I want to draw a string in an SDI using TextOut. But i have co-ordinates in millimeters. How can i convert them into pixels. Help needed urgently...

Ups!! The pixel is the basic unit of programmable color on a display or image so it's more a logical unit than a physical one, altough the physical size of a pixel depends on how you've set the resolution for the display screen:
If the display is at its maximum resolution, the physical size of a pixel will be the physical size of the dot of the display (usually .28mm but you should look to the specs of your display). If you've set the resolution to less, a pixel will be larger than the physical size of the screen's dot (the pixel will use more than one dot).
Hope it helps ...

Hi,
If you call 'GetDeviceCaps' on your device context you can get
the width and height, in millimeters, of your physical screen.
You can also get the resolution of the screen in pixels this way,
so you should be able to do some calculations based on these values...
Don't think you are, know you are...

You could draw the mouse icon yourself by using GetCursorPos, DrawIcon and GetCursor functions. This will only work by attaching your app's thread to the thread that has the window under the cursor. You can do this by using the following functions: GetCursorPos, WindowFromPoint, GetWindowThreadProcessId, GetCurrentThreadId and AttachThreadInput. It's a little messy but it works.

Hi dSolariuM,
This is the way to capture the entire screen
HDC hScreenDC = CreateDC("DISPLAY", NULL, NULL, NULL);
HDC hCompatibleDC = CreateCompatibleDC(hScreenDC);
HBITMAP hScreenBitmap = CreateCompatibleBitmap(hScreenDC,
GetDeviceCaps(hScreenDC, HORZRES), GetDeviceCaps(hScreenDC, VERTRES));
HGDIOBJ hPrevObject = SelectObject(hCompatibleDC, hScreenBitmap);
BitBlt(hCompatibleDC,0,0,GetDeviceCaps(hScreenDC, HORZRES),
GetDeviceCaps(hScreenDC, VERTRES),hScreenDC,0,0,SRCCOPY);
OpenClipboard(GetActiveWindow());
EmptyClipboard();
SetClipboardData(CF_BITMAP,hScreenBitmap);
CloseClipboard();
This code snipet would copy the screen snap in the clipboard.
Hope this would solve your problem.
Have fun !
Cheers,
Vishal

I need a dialog that will query the user for a user name and password, and I'd like to use the microsoft dialog that appears when you try to access a computer that's on an untrusted domain. It's got a user name combo box\edit control, a password edit control, and a 'Remember my password' check box. Too bad I can't attach a screen shot...
Is that dialog an exported class (like CFileDialog), or is there a shell command that I can use?
I'm using Visual Studio.Net 2003, on Windows XP, programming in C++;
Thanks,
Aaron

Yes, the dialog resource is available in one of the main system DLLs. I've seen it before but can't remember which file it's in. Why not just make your own? It'll take all of five minutes.

I have a cancel dialog for an operation that takes a while. The problem is when, in the loop, I try to change a Static control's text on the cancel dialog, it doesn't seem to erase its background (if it's showing a long file name and then a short one, the end part of the long one is still showing). I found workarounds like calling InvalidateRect on the parent dialog, but it causes a lot of flickering... I'm using the following code to process messages while in the loop:
<code>
MSG msg;
while (PeekMessage((LPMSG) &msg, (HWND) NULL, 0, 0, PM_REMOVE))
{
if (!IsDialogMessage(m_hDlgWnd, (LPMSG) &msg))
{
TranslateMessage((LPMSG) &msg);
DispatchMessage((LPMSG) &msg);
}
}
</code>
Is there anything i'm missing?
(I'm not using MFC or anything)
- thanks

Why not invalidate the static control itself.
After setting the new text you want.

Please help me How can i use (dbf) FoxPro files with MFC. I want to open data from dbf file..

MFC supports querying and updating ODBC databases, so take a look at CDatabase and CRecordset, together with an ODBC connection to your .dbf file.

I hate to trouble everyone with such a simple question but I’ve been stuck on this for about a day (I am not that experienced in VC++). I’ve already tried searching everywhere but didn’t find anything that helped me yet. I have a dialog based VC++ program that takes user input and solves a nonlinear partial differential equation. Anyway, I wrote a different dialog based VC++ program which plots the results. I am currently saving the results from the first *.exe to a data file and using ShellExecute() to open up the plotting *.exe file, import the data, and plot the results (just to get things working).
Obviously this approach is poor. I would like to avoid saving the data (an int, 2 1D arrays, and 1 2D array) to the temp file, and get a single application that performs all of the current functions. I tried adding a new dialog to the main project and then selecting “Create a new class” to associate with it. I am able to open this dialog from the main one using
Plotter dlgplot;
dlgplot.DoModal();
but can’t get data to it.
My question is: how can I pass the data from the main class to my plotting one?
Thank you in advance I appreciate any help.

the standard approach is to create member variables in the dialog class that either hold the actual data or that can be used by the dialog to fetch the data. your main class sets these variables before calling DoModal, and your dialog uses them in its InitDialog function to set up / fetch / whatever the data.

I tried doing as you suggested, however, my second dialog's code does not include
the OnInitDialog() function (also recall it has a different class from the main dialog). I added the OnInitDialog() function manually to the second dialog’s *.cpp and *.h files. My code compiles but now the second dialog window no longer opens (it is invoked by a pushbutton from the main dialog) and my main window actually closes when I try to open the second window.
Also, when I tried adding a new member variable "ClassWizard" only allowed be to add a control? What am I doing wrong? Is this really the best approach for my problem?

try removing them, them using the ClassWizard to add a handler for the "WM_INITDIALOG" message.

that's probably because you had the OK or Cancel button selected on the control selector (there's really no way not to have one of them selected on a new dialog).
but, CW is most useful as a way to create and manage message handlers and member variables that are associated with controls. it would be better named "ClassMessageWizard" or something - it's not a generic C++ class handler. if you want to add a member variable to your class, just put it in the .H file for your dialog and either make it "public" or make it private and add public Get/Set functions to get and set the value (the latter is the preferred way, for OO reasons).
