what im trying to do is in a listbox when i left click my menu pops up and that allows me to open my other dialog below is the code to get the string i want
CString temp, temp1;
int nIndex = m_list.GetSelectionMark();
temp = m_list.GetItemText(nIndex, 0);
temp1 = m_sBaseFolder;
temp1 += "\\";
temp1 += temp;
i want to pass that string from one class to the other i just cant get it to pass everything ive tryed when my second dialog trys to open it errors so i dont know what im doing wrong. i just need a function that will return temp1. 
ps. what is the right way to open a dialod from a menu?

Create the pointer of sencond dialog in the first first dialog so that all the member varbales of seocnd dialog can be initialised from first dialog.
Now when you show get the string pass it to the member varibale of Second Dialog CString varibale and with the same object you can display the dialog.
For eg.
You have two dialogs
CFirstDialog and CSecondDialog and you are having CString varibale in Second Dialog class as m_frstDlgString
In first dialog IMplementation file write:
CSecondDialog *m_sDlg;
<br />
m_sDlg = new CSecondDialog();<br />
m_sDlg->m_frstDlgString = temp1;<br />
m_sDlg->DoModal();<br />
<br />
<br />

You will have to declare a pointer of the first class in the header file of the second dialog(assuming you have a class associated to the dlg's).
Now when you are calling the second dialog do this :
CMySecondDlg *mySec=new CMySecondDlg();
mySec->oldPtr=this;
mysec->DoModal();
(Do not forget to include the header files)
Now if your string is defined as CString myString in the first class:
AfxMessageBox(oldPtr->myString);
Somethings seem HARD to do, until we know how to do them.

maybe it is some helpful to you
Main Class is CMain and one child dialog CLocal now you declare this code in child dialogCMain* m_Main = (CMain* )GetParent(); and ues m_Main->(variable)(function)... in main dialog

Hi,
I have an old project at hand and I would like to add some new things to it and compile it into the release file with different name. For example, the old release file is named testing.exe, and I would like to change it to be testnew.exe. What do I need to change in the project to realize it? Is it the only to change project/property/linker/output file?
Thank you very much!
David

Just Go into Linker settings of the Project Settings
and change the Output file as $(OutDir)/testnew.exe

Thanks for your reply. Is it possible to change some code to realize it?

Have you tried the suggestion what given in my previous post..??
no idea... for changing the name of the exe through code.
if you want more accurate so that your exe property pages also revert the changes of the new exe then
go to Resource>Version in case of Windows application.
and modify the internal file name and Original file name
but changes the exe information not actual exe name.

Thanks a lot! It seems the method in your first post is so far the only solution I could find. Thanks again.

why we can't change the exe file through code??
Reason may be as follow..
The Exe which is in execution mode is locked,so that no one can change the file/exe name hold br Exe (Here exceptional case is shared resources)..even you can't delete the directory under which your exe reside and is in execution.
When the execution completes then the resources hold by the exe released and you can do whatever you want.
Conclusion is you can change the name of the exe through code of other executable not the same executable which is executing your code of changing the exe name.

In Menu Project->Settings->Link Tab->In outputFile Name,enter new EXE name.

Posting the same information from more than one person does not warrant such a response. In many cases, those posts to which you refer have not been made at the time of responding. For example, I may have a dozen browser windows open, each with a different thread, sometimes to the same thread. If I am replying to several at once, it may be 5-10 minutes between the time I clicked Reply and the time I click Post.
In any case, if the OP receives several responses with the same solution, s/he can be assured that the given solution must be correct.

Thanks for your guidance.

Hello everyone,
What is the convenient way to calculate the execution time of a function? The function may be not a long and time consuming function -- only 10 lines in some situation.
thanks in advance,
George

One of the ways could be to use QueryPerformanceCounter()

Thank you _AnShUmAn_!
I have tried the method, and the results are in LARGE_INTEGER structure. Do you know how to calculate the difference between two LARGE_INTEGER structure variable (the difference of begin time and complete time)? I have tried to use '-' sign, but there are compiling errors.
regards,
George

use GetTickCount function before and after the function and take the difference. But it only have a resolution of 15 milliseconds. For high resolution use
QueryPerformanceCounter()

check this
LARGE_INTEGER tBefore, tAfter, iPerfFrequency;
float TimeElapsed;
// to determine how often the performance counter increments
QueryPerformanceFrequency( &iPerfFrequency);
// Get performance counter before the function
QueryPerformanceCounter(&tBefore);
MyFunction() // Call the function for which the performace is to be calculated
QueryPerformanceCounter(&tAfter);
TimeElapsed = tAfter.QuadPart - tBefore.QuadPart;// finding elapsed time
TimeElapsed = TimeElapsed / iPerfFrequency.QuadPart;
cout<

Thank you nave!
I have tried your code, and it works cool! I have also referenced related MSDN document, and I think your method will print out the elapsed seconds, right?
regards,
George

I think better way would be try to find out the Time and space complexity for the function and then use the QueryPerformanceCounter().
