You can use cygwin ( http://www.cygwin.com/ ) on windows. While installing the cygwin you need to select the packages you want to install in cygwin some of the packages are gcc, vim editor, some library.

Is it an uncompiled cpp file, or an executable created using c++? You cannot execute a cpp file.

I have made some important changes to the VC tool box and I can find nowhere to save the changes.
Is it possible to save the changes? such as locate the file ,save it, then after the vc's reinstallation, recover the file so that I can access the changes I have made to the tool box?

Try saving the files in the folder C:\Users\<user name>\Documents\Visual Studio 2010\Settings.
I'm not sure if this file includes the toolbox settings.

Simply make the child dialog a modal dialog.
This way the parent dialog will become inaccessible when the child dialog is visible.
If using MFC, call the DoModal method to display a modal child dialog.
If not using MFC, call the DialogBox API to display a modal child dialog.

That is as it should be. If you want to be able to access the parent, then you need to make the child dialogs modeless.
The best things in life are not things.

You can make a modeless dialog by API CreateDialog, which when open giveS you the ability to access both the parent window and child dialog box.

i have done it with huge integers so far but there is a problem that when i operate anyt function like adding or multiplying there become a dot after my answer and when i try to write again a new value that become written after that dot and previous answer stays on screen. what should i do???

Without snippet of code, this will be very difficult to answer (and please don't post the full code, only relevant snippets).
Did you try to use your debugger ?

Send a letter to the Microsoft, asking for the source code of their calculator application.

You need to be a bit clearer on what you want. "32 digits" implies decimal digits but I suspect you may bew talking about 32-bit numbers (ie 32 binary digits) or perhaps 32 hex digits. Also do you just want to calculate using these large numbers or do you want code for a calculator type program with buttons etc.
My best guess is that you just want to do calculations on big integers up to 32 hex digits (128-bits). These sorts of numbers are use in things like encryption. I have used the code in this article with success: C++ Integer Class[^].

I have fetched unicode data from microsoft database access in cstring variale as below
_variant_t dataHnd;

data2=dataHnd.bstrVal;
but in data2 variable ???? shows instead of hindi unicode data.
plz anyone tell me how i can get hindi unicode data in string variable

You can use the code like this also...
<br />
TCHAR szMsg[256];<br />
_tcscpy(szMsg,OLE2T(dataHnd.bstrVal));<br />
I hope this might help you...

Do you have _UNICODE and UNICODE defined in your project configuration? These will force CString to wide character.

Hi,
I need to add a log viewer in my application but as well as I need to put a buttons on top. How can I do that?
|
|
|
|
|
Use visual studio resource editor.
|
|
|
|
|
You really should provide more information if you want a useful response.
Is the viewer going to be in a modal/modeless dialog or a separate program and have you considered these alternatives?
Are the buttons you want to add going to be in a tool bar, plain buttons or owner drawn?
Keep it simple

I noticed that the main.cpp in a Qt application has to contain the following line:
QApplication app(argc, argv).
I know that argc is the number of command-line arguments, and argv is that array list of command-line arguments. But, the question in my mind is: what are those arguments I'm passing to the constructor and at the same time cannot explicitly see? What is working behind the scences out there?
Thanks.
