UI frozen=Sleep worked... like it was suggested, create a loading thread and have that thread message back to the original thread when he's done. Using Sleep() in this manner is not acceptable, you're freezing the user interface on purpose, many do it on accident, but on purpose!?

So does that means using Sleep() (in main thread) in mfc in condemned??? I never realized that. I think a lighter way was what I did (activated a timer and went to sleep there). Thread is also a good option. Thanks for the reply.

It's condemned to use Sleep()(for this length of time) in UI thread(its common for people to separate the UI from the rest of the code).

How do i find last created file in a specified directory?
|
|
|
|
|
Enumerate the files using FindFirstFile & FindNextFile. Using WIN32_FIND_DATA compare the properties and time stamps or whatever is required. You will need to compare the file creation times using an algorithm
FILETIME ftCreationTime; will be of interest in your case.

You should check the results of
GetLastError() after each API call to try and determine why your code is failing.

Hi all,
I have made a CString variable in that variable i have a single character value like A,B,C.....
I want to put this value in simple char variable(not into char* or char[]).
How can i do so????
thanks in advance

CString can be compiled in UNICODE or NON-UNICODE mode.
In NON-UNICODE mode, the underlying data type is a char.
But in UNICODE mode, the underlying data type is a wchar_t.
So in UNICODE mode, you may not be able to directly assign a single character to a char variable using the GetAt function or []operator.
Here is something you can do so that it works in both UNICODE and NON-UNICODE builds -
CString str("Hello World");
CStringA stra(str);
char C = stra[6];
|
|
|
|
|
Use CString::GetAt() and pass it ti WCHAR or TCHAR - whar ever you are comfertable with...

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.

It's amzing. I've found the data in that settings file. Thanks.

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.
