Hi All,
I have been using CString for years and was very much comfortable with it.
Now i am using STL's string.
while debugging i am not able to get the value of a string variable.it shows the address and not the value(string::c_str).
if it was a CString variable, just by putting the variable in the Quick Watch i was able to see its contents.
How do i get the value of a string variable during debugging ?
Thanks in advance

It almost sounds like you need to add an entry to your autoexp.dat file. You'd see the same thing with CString if it weren't for that file.

Hi David,,
I'd be very interested to know what you exactely mean with your answer. I thought there was no (easy) way to see the content of stl strings while debugging... What is autoexp.dat ?

I don't use STL, so that may very well be the case.

It's a file located in the C:\Program Files\Microsoft Visual Studio\Common\MSDev98\Bin folder. There is a good description at the top of it.

Use
<br />
dlg.m_ofn.lpstrFile=TEXT("DefaultFile.xxx");<br />
before DoModal()
Have a nice code day

I need to open a file named "1.bmp" located as "c:\1.bmp"

ASSERT(AfxIsValidAddress(m_ofn.lpstrFile, m_ofn.nMaxFile));
My code is somthing like this :--------
CFileDialog dlg(TRUE,"bmp",NULL,OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,"Only BMP (*.bmp)|*.bmp|");<br />
<br />
dlg.m_ofn.lpstrFile=TEXT("c:\\1.bmp");<br />

I don't know, it is strange! 
A good thing could be add the flag OFN_FILEMUSTEXIST here:
CFileDialog dlg(TRUE,"bmp",NULL,OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,"Only BMP (*.bmp)|*.bmp|");
So you are sure that the file exist.
And I don't like very much
...,"Only BMP (*.bmp)|*.bmp|"
I prefere
...,"Only BMP (*.bmp)|*.bmp||"
Let me know
Have a nice code day

If lpstrFile is assigned a non-NULL value, so must nMaxFile also be used to indicate the size of the buffer pointed to by lpstrFile.
Why do it this way, however, when the constructor already has provisions for such?

That is what the third parameter of CFileDialog's constructor is for.

Then why bother with CFileDialog if you already know the name of the file?
Also, the filter should end with two ‘|’ characters.

A callback function is a normal function that the system calls when comes specified events.
An event could be a mouse click, or a tollbar botton click, ....
To link the event to the function it is used the MESSAGE_MAP
(usually in this macros are used the IDs of the objects that the user is using)
is it OK?
Have a nice code day

fisrt of all thanks for your patience,
for the first time i think i've understood whats a callback.
See here
LRESULT CALLBACK WndProc(HWND hwnd, UINT msg,WPARAM wParam, LPARAM lParam)
as i've read,WndProc processes all the messages send by the applications. right? so a message "coming" makes an event which inturn calls this CALLBACK wndProc right? am i right?
