i dont understand why is dwValue ignored and dont output just RegSZ... It echo non exist values oO

Read the MSDN article on RegEnumValue[^] carefully. Pay attention to which parameters are labeled [in] as they have to have valid data before the call, and which are labeled [out] as the data in those will be changed by the function call. Also make sure your buffers are large enough to recieve the data. read the comments at the bottom of the article for information on how to get the required buffer sizes.

Hello, I have a MDI type app where one of my views was derived from CView and then converted into CRichEditView...
Anyway everything works fine except I want to turn horizontal scrolling on and I would like to disable word wrapping. I have tried to change the window styles in PreCreateWindow but this doesn't seem to have any effect on horizontal scrolling. Any ideas? Has anyone had similar experiences?
Thanks,
Rob

Hi Forum,
how can i calculate a time difference between 2 files, my problem:
when i want to create a new task, i check first the starttime of the existing task and i want to have min. 2 hours space between a starttime of a existing task and the new one!
Existing Task gives me starttime in SYSTEMTIME variables return and i convert this in COleDateTime variables, and the new time come out a CTimeControl so i want to check the time difference between SYSTEMTIME or COleDateTime variables and CTimeControl, is there a function to calculate a time difference between this two?
thanks

The easiest way is to convert everything to FILETIME, which is a 64-bit number. Comparing and making time spans is then really easy since you just add or subtract.

Hi, i can't convert to FILETIME, i got an Error?
FILETIME newTime = nTime; // nTime is a COleDateTime Variable!'initializing' cannot convert from 'class COleDateTime' to 'struct _FILETIME'
FILETIME oldTime = oTime; // oTime is a COleDateTime Variable!'initializing' cannot convert from 'class COleDateTime' to 'struct _FILETIME'
With typecast a got an error to!
FILETIME newTime = (FILETIME)nTime;//'type cast' : cannot convert from 'class COleDateTime' to 'struct _FILETIME'
 
thx

Have you looked into COleDateTimeSpan?

Create a modal dialog with two edit controls: one for the username and the other for the password.

This question is not for creating edit controls. This question is to know about Windows credientials. Windows users.
May be the answer reside in Microsoft security tokens.
thanks for replying either.

It could have been interpreted any any number of ways. You stated that "...the user will have to enter a administrator username and password to have acccess to some additionnal informations." followed by the question "How could I do this?" My answer was simply how to allow the user to enter such information.

I am working with SDI.i created a menu in one fo the view.The menu items are not enabled from another view.how can i resolve the problem.if any one come across it pls let me know.
|
|
|
|

This depends where the functions are.. If your functions for each menu item are in CMainFrame then the menu items should work across all the views. If the functions are declared inside the view or child frame then only that view or child frame will show the menu item as being enabled.

Hi
I have developed one Windows Service which runs after certain interval. It runs on Windows 2000 Professional OS.
Most of the code I have written in C++.
It's a multithreading application in which first when service starts it creates one thread called MasterThread. Then Master thread creates 100 ChildThreads.
First it creates all the 100 ChildThreads in to Suspended mode and when I need it I resume that thread.
The problem is like some time it creates only 20 Threads and it stucks execution over there. Some time it creates 80 threads or something like that and then it stucks. And some time it works fine creating 100 threads....
also sometime it gives error after running successfully for 2 to 3 hours. The error message Showing one dialog box like :
" Runtime Error!
Program : C:\Services|MyService.exe
R6025
-Pure virtual function call "
Does anybody know what these both problems are happening. Is there any limit on how many threads we can create on Windows 2000 and if we want to create more than that limit then what to do ?
Why it gets stuck after creating some number of threads...?
Pls help me...
Thankx in advance

Maybe there is a problem with the synchronisation between the threads. Make sure all variables shares between the threads are secured by mutexes, critical sections or other synchronisation mechanisms.
The error you described could be caused by a global class that is initialized by one thread, and accesses by another one at the same time. You have to be very careful with multithreading, it needs lots of planning that it really works without any problems.
Don't try it, just do it!

I've managed to host a web browser window in my program but am unable to work out how to handle events fired from the browser window. I know it has something to do with the DWebBrowser2 interface but how do you hook it up? The program is written in plain Win32 ie. not MFC, ATL etc.
