it was working perfectly fine on my computer with compiler. When i brought it to another computer, this happened!
i tried redoing a new testing project and creating the webbrowser in the same manner and it was good
some information:
- using MFC
- created webbrowser2 by going to dialog editor, right click and select "insert activeX"
- disabled firewall on both computer
- both computers definitely have internet connection with IE 7
- m_webbrowser.Navigate runs in a worker thread
- the target website yahoo.com is definitely up. i checked with my firefox and IE browser
- no delay, noticed. which means webbrowser2 did not neven attempt to contact the site
can anyone please help?

i have narrowed the problem down to the navigate member function being run in a worker thread. however i cannot find the root cause to the problem

You need to pass a valid URL, such as http://yahoo.com

In my main scope i declare my pointer variables :
...
PSID ownerSid = NULL ;
PACL pDACL = NULL ;
ownerSid = GetOwnerSIDFromFile (path);
pDACL = GetDACLFromFile (path);
if(ownerSid) FreeSid(ownerSid);
if(pDACL) LocalFree(pDACL);
...
PSID and PACL still cause leakages altgough i try to release them. How can i handle that situation ?
Here are 2 functions i call :
PSID GetOwnerSIDFromFile (char* sFileOrFolderName)
{
DWORD dwRtnCode = 0;
PSID pSidOwner = NULL ;
HANDLE hFile;
SID_IDENTIFIER_AUTHORITY SIDAuthWorld = SECURITY_WORLD_SID_AUTHORITY;
hFile = CreateFile(
sFileOrFolderName,
GENERIC_READ,
FILE_SHARE_READ,
NULL,
OPEN_EXISTING,
FILE_ATTRIBUTE_NORMAL,
NULL);
if (hFile == INVALID_HANDLE_VALUE)
return NULL ;
AllocateAndInitializeSid(&SIDAuthWorld, 1, SECURITY_WORLD_RID, 0, 0, 0, 0, 0, 0, 0, &pSidOwner) ;
if( !pSidOwner )
{
CloseHandle(hFile);
return NULL ;
}
dwRtnCode = GetSecurityInfo(
hFile,
SE_FILE_OBJECT,
OWNER_SECURITY_INFORMATION,
&pSidOwner,
NULL,
NULL,
NULL,
NULL);
CloseHandle(hFile);
return pSidOwner ;
}
PACL GetDACLFromFile (char* sFileOrFolderName)
{
PACL pDACL = NULL ;
DWORD dwRtnCode = 0;
HANDLE hFile;
hFile = CreateFile(
sFileOrFolderName,
GENERIC_READ,
FILE_SHARE_READ,
NULL,
OPEN_EXISTING,
FILE_ATTRIBUTE_NORMAL,
NULL);
if (hFile == INVALID_HANDLE_VALUE)
return NULL ;
pDACL = (PACL)LocalAlloc(LPTR,sizeof(PACL));
if( !pDACL )
return NULL ;
dwRtnCode = GetSecurityInfo(
hFile,
SE_FILE_OBJECT,
DACL_SECURITY_INFORMATION,
NULL,
NULL,
&pDACL,
NULL,
NULL);
CloseHandle(hFile);
return pDACL ;
}

All,
I had a small task at hand of tracing out the contents of a packet(generally a binarry array) and was looking for a sample code on web to quickly do it. Couldn't find any, so wrote my own small function. I wanted to share this on this site. I am sure it would be helpful to many sorry souls like me .
I am already a registered member of this site. But I don't see any link on how to post a small code snippet.
Please adivse.

You're describing an article. A code snippet is useless without some text to describe what it does, and how, so you'd want to write a short article and use the article submission wizard to submit it, and the code.

I'm running Visual Studio 2005 and I have a specific key set for toggling between full screen and windowed mode -- F10. The following is a section of my code that runs in a while loop and handles my messages.
while (!m_terminate)
{
if (PeekMessage(&msg, 0, 0, 0, PM_REMOVE))
{
if (msg.message == WM_QUIT)
m_terminate = true;
else if (msg.message == WM_KEYDOWN)
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
else
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}
}
Now, when I set a breakpoint at if (msg.message == WM_KEYDOWN), whenever I press a key in my program, Visual Studio will break at that line and allow me to debug into it. This works all the time except for when I press F10 (I have a few other keys for toggling things). When I press F10, my program will hang for a little while, and then just continue working as if nothing happened, and my breakpoint will not be hit. I'm curious as to why this is. Anyone have an idea?
I guess I should mention that I have declared MESSAGE msg; outside of the while loop.
MODIFIED: It seems like the F10 key is a special key that is handled differently from the others.

Here's an addition to my problem. The F9 key is OK (VK_F9), but the F10 key is still not (VK_F10). VK_F9 = 0x78, VK_F10 = 0x79, as expected. Is there something in the details that I should know but that I've completely overlooked (such as VK_F10 being reserved for some kind of system use only, or whatnot)?

Only thing I can think of is that F10 is usually associated with "Step Over" when debugging. You could try re-mapping that command in the IDE to some other key.

That's a thought that I had as well, but even when I compile it as release and run it directly from the executable without the debugger, it doesn't work.

Ultra short question : D.
hbmpBackground = (HBITMAP)LoadImage(NULL, (LPCSTR)Path, IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE | LR_CREATEDIBSECTION);
Can I find out the size of hbmpBackground? With x Heigh in pixels?
|
|
|
|
|
<br />
BITMAP bm;<br />
GetObject(hbmpBackground,sizeof(bm),&bm);<br />
int width = bm.bmWidth;<br />
int height = bm.bmHeight;<br />
DeleteObject(hbmpBackground);<br />
Best Wishes,

I am in BE final year & I am required to do a project.
Friends plz help me in this & suugest me some good topics, I am not asking for any code, I just need TOPICS.

There are thousands of topics on the CodeProject web site alone;
some are solved (articles), some are not solved (parts of the discussion boards).

How about a multithreaded game engine using a specific graphics API capable of navigating through a heightmapped terrain?
|
|
|
|

Don't you have a topic/thesis advisor for this? I would think that a final-year student would be well-equipped to do this sort of thing with little guidance.

How can i get list of installed softwares on system via Registry ( in my project i mustnt use MSI)
Thank you very much
|
|
|
|
|
Look at the keys under HKLM\software\Microsoft\Windows\CurrentVersion\uninstall
|
|
|
|
|
Thank you very much , but is there a way to get datas of MSI-style installed sws ? For ex. how can i get publisher or version data from registry ?
Regards
|

Did you bother opening the registry and navigating to that hive?  You have the publisher, version and all other information there.

There are APIs for getting that info from MSI. The APIs all start with Msi so they'll be easy to find.
