It's an English thing. In his question, desktop is an adjective, describing the type of shortcut. It would have been the same as, "How can we programmatically remove a shortcut icon from the desktop?"

Hello everyone,
Suppose a program looks like,
--------------------
code block 1;
if (condition == true)
{
code block 2;
}
--------------------
I want to see the state of block 1 (variable values) if condition is true. So I am wondering whether Visual Studio supports backward debugging, if it supports, I could set a breakpoint at the beginning of code block 2, and if it is executed, I could run *back* to the beginning of code block 1 to execute code block 1 again see the detailed running process of code block 1.
thanks in advance,
George

You can set the execution pointer to anywhere you want, but you have to be careful with this because it can make your code behave rather strangely sometimes.
If you just want to see the variables from code block 1, just use the watch window.

Thank you Zac!
I would like to know your comments/advices for my issues below. I have described it in more details.
But in my situation, it is hard to know the condition before an error occurs ... means the condisiton is not predictable and there is not a fixed a rule for defining conditions. The only point where I can find errors is, the execution of code block 2.
In more details, I want to monitor the original values, which will incur the error. For example, code block 1 will be executed a lot of times and code block 2 will only be executed when there are some errors. I want to set a breakpoint to the beginning of code block 2 and find the states of variables in code block 1 when there are errors. I can not set a break point to the beginning of code block 1 since it will be executed a lot of times even if there are no errors ...
regards,
George

Set a breakpoint at the start of code block 2. Run your application in debug mode. When you reach the breakpoint, use the watch window to look at the variables you need to see (as long as they are in scope). Now, if this is part of a catch block, make sure your variables are declared outside the try block so that you will be able to see them.

Hi Zac,
In code block 1, there are some function invocations, which has some local variables in function stack, such variables can not be monitored outside when returned back to code block 1/2. Any ideas?
regards,
George

Several. You can set a conditional breakpoint on any of those local variables you want to watch. Or you could add some variables to the scope outside of those calls to just store the values of those variables for debugging purposes. Additionally, you could always add code to output important data to a file as it goes through your code.

Thank you Zac,
The idea of setting a conditional break point is not feasible for me, becasue the value of variable which will cause error is not predictable (image some mathematics operations ...).
So, I have to write some additional code to some place, a file or the console. But actually, I do not want to add them since I am debugging some race conditions in a multiple threaded application, and I concern that if I add some additional debug code, the race condition will not occur. And, I only release application without debug code ... I mean I want to test the application the same as the one I will release (without debug code).
Any comments or good points to solve this?
regards,
George

But you do know the valid values for such a variable I take it?

You may not want to, but you may have to in order to find your bug. You can test your release builds all you want, but if you are not able to find the cause of your bug, you need to start gathering more information. If the race condition does not occur when you add output information, at least you would have tried -- and if it does still occur, you would have more information about where it might be. Debugging is largely trial and error.

I mean in some situation, the value 100 for variable foo is correct (not causing errors) in a complex system, but later, the value 100 for variable 100 is in-correct (causing errors). It is highly dependent on other threads running at the same time. Have I made myself understood? 
Any ideas?

George

I think I understand your problem, but there is no real easy way to debug it.

Thank you Zac,
Do you mean the best solution I could use is to debug some codes to manually dump the values of the variables I am interested to somewhere, and to monitor/analyze them later when error occurs?

George

hi, all:
I've developed a bho plugin for internet explorer. It simply receive the DISPID_BEFORENAVIGATE2 event and change the address in the address bar. It's event-driven and I think it will not cost too much cpu. But to my surprise when it's loaded into IE, the cpu usage turns to be 100% and I can do nothing else.
Why it costs so much cpu and how to resolve this problem?
Thank you very much!

what is the Difference between C++ and VC++ ?
|
|
|
|
|
This has been asked several times before. In short, VC++ is Microsoft's version of the C++ language.

My understanding is that DOS C++ is for Console based applications. Once you get into Visual C++, you can develop Windows-like applications - applications containing menus, buttons, dialog boxes and many more features.
Somethings seem HARD to do, until we know how to do them.

That's backward compatibility.
