What happens if you comment out the second SetPaneText() statement? Does "in progress" remain in the status bar?

Could it be that the code in between the two calls to SetPaneText() is just happening too fast?

no,its a long process...it takes 3 to 4 mins

It sounds as though your long process is taking up all of the CPU such that the first SetPaneText() does not get a chance to paint (i.e., the WM_PAINT message has not been processed).

I would use a secondary (worker) thread to do the work. That way the primary thread can remain responsive and handle painting.

Hi Friends,
Can I do something like this ? Is it portable across all platforms ?
<br />
int* ptr = new int();<br />
int& tmp = *ptr;<br />
delete &tmp;<br />
|
|
|
|
|
I am not sure about portability issue but is there any specific reason to do this? These kind of smart-ass statements makes code harder to read and maintain.

My design of stuff is another issue.
Basic question here is
- is this a standard practice?
- Are there any issues?

It mostly depend if you are interested in generic programming and in having value vs pointer semantics.
until &*&x == &x whatever x, than what you did is true.
Of course if x overloads * and/or &, things may be not be as expected, but sometime this is wanted by certain generic algorithms.

Another hint for not to be in trouble - if you delete by using reference, then the ptr variable will become a dangling pointer.

M making a search application in that m using SHBrowseForFolder, while running the application, when we click on the BRowse button second time then i want the previous folder(which we selected when we pressed first time) should come as selected. But now Mycomputer is coming selected everytime i click the Browse button.
Please someone tell me how to do.
This is my current code
void CTestingDlg::OnBrowse() { BROWSEINFO bi; TCHAR szDir[MAX_PATH]; LPITEMIDLIST pidl;
|

Hi,
I am not sure there may be some standard method, but you can save the previously opened folder path in an INI file.
When open dialog next time, initialize BROWSEINFO->pidlRoot to the previously opened folder path from INI file.
Hope you got some idea..
Thanks,
Suman

Most applications use registry to get the last file that was opened. You can then use a parameter in BrowseInfo to open the previously selected folder.
Somethings seem HARD to do, until we know how to do them.

The size of object of a class that contains int variable is 4bytes then why the size of class 1byte is not considered along with 4bytes?.
|
|
|
|
|
I don't quite understand what you are asking? But I will make a guess. You are saying that a class containing since int will have objects of size 4 bytes. Then why does empty class takes 1 byte instead of 4 bytes? Because 1 byte is enough for the purpose of differentiating two objects of an empty class. So why use 4 bytes and waste 3 bytes per object?

My previous question is not so clear, let me clear my doubt here
class A
{
};
class B
{
int k;
};
int main()
{
A a;
int i = sizeof(a); -----> the value of i is 1byte
B b;
int j = sizeof(b); -----> the value of j is 4bytes
return 0;
}
why the value of j is 4bytes why not 5 bytes[size of int variable(4bytes) + size of class(1byte))

class objects have to have non zero memory size.
In case of class A it is empty since compiler cant determinne the size it will allocate minimum allocation unit i.e. 1 byte for its object.
In case of class B it has int variable so compiler knows its size and hence will allocate appropriate size i.e 4 bytes for int for its object.

Sandip.

Because class B now has data, and doesn't need to insert a byte to maintain memory integrity.
