Hi All,
I want to instrument a C++ program by entering probes inside every block.
But i m finding it difficult for single statement condition statements without braces.Eg
If(x==2)
stmt;
Else
stmt1;
I want to put braces in the program so that i can insert my probes in them.
|

The solution is simple: just put braces in!

It sounds like a real pain, but it also sounds like you already know exactly what you have to do to accomplish this. I don't think there is an easier way.
You do realize that the probes you are inserting will impact your program and make the source code more cluttered difficult to deal with and maintain correctly.
Have you looked at different profiling tools? Perhaps there is one that would be an easier answer for your needs.

Visual Studio 2008 (not sure of 2005) has a built-in feature to instrument and optimize applications.
Check if this is suitable for you.
You will find this under the menu option Build -> Profile Guided Optimization

Hi All,
I want to disable the mosue movement in a MFC view application if the control is in an edit box and user entering data in the edit box. I want to get back the mouse movement once user presses enter key in the edit box, can anybody tell me how can I do this in MFC view application

why?
it seems to be counter-productive in a multi-application OS like windows.

I have multiple modeless dialog with each dialog have some edit box controls on it. So when user entering data in to an edit box of modeless dialog and at the same time if user moves the mouse away from that modeless dialog the focus is changing from the edit box to parent window which is making wrong values to be set in the edit box. So I want to disable this mouse movement until the user done with data entry into the edit box. yeah it seems like counter-productive but the requirment is like that

This is exactly why you should use a modal dialog in this instance.

While I'm not sure how good an idea it is, perhaps you want to look into mouse capture. See here and here. You could try to capture the mouse on first character entered into the control and release it on tab or enter. I'm still not confident that this won't be misunderstood by users and frustrate them.
Edit: Richard's response is better. Listen to him.

Simply moving the mouse should not change the focus state of the dialog and/or edit box currently being edited.
Me think you have a bad design (as other wrote), at least the way you update your values.

You might want to rethink this. It is an unusual approach and will be misunderstood by users. Having the mouse cursor disappear or become unresponsive will be interpreted by many users as a program hang. Some will respond by bringing up task manager to kill your program. Others will reboot their computer to get things working again. Neither is a good thing. (Yesterday I was trying to help a user who is using some buggy, no longer supported legacy software. He would have done ;exactly this ;with no hesitation.)
Perhaps you could validate the data at some point and notify the user if it is invalid. You could even set focus back to the offending control.

I am trying to change the working directory of a MFC application after
the application execution begins.
Chdir or setcurrentdirectory doesnot work for a MFC application.
Can anyone suggest how i can do this?
|
|
|
|
|
SetCurrentDirectory works in MFC.
Check if your path is valid.
Also you could use GetLastError after the failure of the function.
If the path is OK then some relevant code snippet about your problem could also help us to find the problem.

Hi all,
I have a binary image (white objects and black background). I want to find the nearest white pixel for every black pixel of the image. How can implement it in c++.
Thanks in advance,

One possibility:
Making desired black pixel as center of your search and then exploring the pixels around, if not found increasing in 1 your search radius and try again, when you have a hit in white, getting its coordinates and making the modul of the vector from point A to B to get the distance.
But by all means:
Starting code and reading this[^]

Hi All,
I have an application that is loading a iso file. iso file has many packages to complete the application but it takes time to open an application because everytime it load all packages. So I want to take snapshot like thing So that i can resume the application from where I left it before.
Is there any mechanism to do so?

An application may save its state in order to continue his work at next startup. Have a look at the Memento design pattern [^] (also have a look at the beautiful Memento film ).

I think just a dumb interviewer may ask such a question.
