You can use CRegKey like so:
CRegKey reg;
BOOL ret = FALSE;
if (reg.Create(HKEY_CURRENT_USER, "Software\\YourApp") == ERROR_SUCCESS) {
reg.SetValue("Value", "Name");
reg.Close();
}

Thanx a lot.. but how can i come to know whether the
Key already exists..
Actually i just want to create if it does not exist..
And also can i make multiple subtrees

Hey~
I think I may have found a bug in Visual C++ with MFC. Could someone please either confirm it as a bug or offer a suggestion to fix the problem?
I've overridden PreTranslateMessage and OnInitDialog for every dialog in my app as per MSDN to support Accelerators... I even communicated with Paul DiLascia about this. Plus I've overriden ProcessMessageFilter and InitInstance in my main app class to support application wide accelerators. Everything works fine, EXCEPT when the focus of my application is on the WebBrowser control that I have on a dialog, and I hit the Ctrl+O key combination. I have set up my accelerator resource to map Ctrl+O to a function that I have. This function never gets called. If the focus of my app is ANYWHERE besides in the WebBrowser control, it works perfectly.
Is this a bug?
I placed TRACE calls in my PreTranslateMessage and ProcessMessageFilter functions to observe what was happening when I tried the various "hotkey" combinations. Everything worked as expected, but when I tried the Ctrl+O while the focus was on the WebBrowser control and the following message was displayed in the debug output for the app within Visual C++ 6.0.
Loaded 'C:\WINDOWS\SYSTEM\BROWSEUI.DLL', no matching symbolic information found.
I don't know if that will help anyone figure this out, but...
It seems as if the WebBrowser control is capturing the Ctrl+O and discarding it. Shouldn't the ProcessMessageFilter in my main app class capture this before any control gets a chance to?
I've been trying to figure this out for about 2 weeks now... someone HAS to know how to fix this...
Thanks in advance,

No, if the web control has the focus, it will get first dibs at processing the message. That's what I would expect, anyhow. Is the web control passing other key messages through to your main window ? Can it be set to ?

Yes, the web control is passing the other "hotkey" combinations through to my main window... just not Ctrl+O. I don't know if it can be set to... I have looked all over the place and scoured MSDN and haven't found any solution. There has to be one... I just haven't found it yet, I guess. Or maybe it's just that I wasn't looking for the correct thing.
thanks,

One possible solution is to inherit your own class from the web browser class, sub-class the window and intercept the message in your derived class before it sinks th messahes and loses it for you.
Not sure if you can do this with web broowser controls etc (I have no experience with them)

Is there any way to timeout receive function?
I mean,if no data is send to me and I'm receiving. How
I could stop this receiving nicely? For example
in 30 seconds?
My code:
do
{
cout << "Socket Receiving" << endl;
nRead = tmpSocket->Receive(ReceiveStr, RECEIVE_BUFFER_SIZE);
strBuilder.addString(ReceiveStr, nRead);
} while (nRead == RECEIVE_BUFFER_SIZE);
|
|
|
|
|
Use setsockopt function. For example:
int timeout = 10;
setsockopt(tmpSocket, SOL_SOCKET, SO_RCVTIMEO,
(char *)&timeout, sizeof(timeout));

i have inserted a background image on my dialog by using pDC->StrecthBlt(...)
and i could not be able to set the background of my static controls into what my dialog is although i have set my Background mode to TRANSPARENT (pDC->SetBkMode(TRANSPARENT).
They still have "gray background color" and i have trouble with them.
Anyone who have an idea to solve my problem?
Thanks for ur help...

I don't believe that is what this means. I think the only way to draw your controls background is in your control.

when i used the brush method (-> CBrush.CreatePatternBrush(CBitmap)...)to paint my dialog background none of my static controls have gray background color. They have the same when i use TRANSPARENT in SetBkMode().
But when i use StretchBlt() they have gray coloured backgrounds on my dialog.
what is the problem then?

Hi this is my first thread here 
I try to use IHTMLImgElement::put_src(BSTR) to set the <img src="xxx.gif"> tag, but it does not work.
The html document is the following codes:
<img src="../images/face.gif">
I want to change it to:
<img src="C:/images/face.gif">
I have already got the printer of IHTMLImgElement:
src=L"c:\\images\\face.gif";
p->put_src(src);
Does not work
BTW: i want to set the value of <A href"xxx" tag, too. How to do it?

Hi,
How can i take a screen shot of my screen ... (vc++)
and what the best method..
Sameer

Well, it's probably not the *best* method, but if you do an ALT-PrintScreen, you can then paste a bitmap of the active window into Paint/PSP/Photoshop/Your favorite graphics program.
I know there are programs out there that make screenshots a painless process, but I must enjoy the pain of manually taking them, because I have no idea what those programs are.

If you mean programatically, if you're using MFC, CWindowDC screen(NULL);, then you can blt it to the bitmap of your choice. Otherwise create a DC with the string "DISPLAY" in Win32.

Dear,
I am a student of Computer Sciences. I need some help regarding Network Interface Card.
I have two network cards installed in my system. I want to make a program which should assign single IP to both cards. I have two independent networks attatched with one machine. One network is attatched with NIC1 and other is with NIC2. I want both network to send data over one IP address. Can anyone help me to build such application.
If anyone can guide in such application, please do it.
your help will be highly appreciable

Write your own (kernel-mode) driver. Using the same IP for two NIC's in one machine just doesn't makes sense. Actually, it's worse, since you couldn't select what interface to e.g. bind() to!
Perhaps you could explain what you _really_ want to do, and maybe a solution will surface?

Hi.
I just found a major multithread bug a program I working on. First, I will describe the process that is causes the major multithread problem.
-----
- user opens a text file (any size) w/ text only
- user clicks an option in the menu
- view has a executes its message handler for the menu item
- view calls a function in doc
- doc begins a new thread (thread includes CSinglelock + CriticalSection, data from doc)
- thread resumes and begins processing the data
- when done, thread *PostMessage* mainframe that is done ::: -> AfxGetMainWnd->PostMessage(WM_USER_THREAD, 0, 0);
- main frame *SendMessage* to view ::: -> pView->SendMessage(WM_USER_THREAD, 0, 0)
- view calls a function in doc to close thread
- doc class this function
-----
////
// This function is called to close a thread
//
m_bThread = true; // meaning thread is still active
if (m_pThread && m_hThread) // m_hThread is a HANDLE to the thread
{
::WaitForSingleObject(m_hThread, INFINITE);
delete m_pThread;
m_pThread = NULL;
m_hThread = NULL;
m_bThread = false; // meaning thread has been closed
SetModifiedFlag(TRUE);
}
UpdateAllViews(NULL);
-----
Okay. Everything works good *if the use does not click anything* during the process. In other words, if the user were to click the menu or anything inside the window, the program would malfunction.
Notice the bool "m_bThread." I use it as an indicator about the status of the thread. if m_bThread is true, meaning that the thread is active, the program disables many options in the menu. These options will remain disabled unless m_nThread is false. For some reason, that variable remains *true* if the user starts clicks anyone in the menu or view processing. That means something is keeping the program to ever setting m_Thread to false. On the other hand, if the user does not click anything until after the process is over, everything works as planned.
I have no idea what is going on in the background. Is there a design flaw anywhere?
Thanks,
Kuphryn

This doesn't close a thread, it simple waits for thread to end. My guess is that you have deadlock occuring between your worker thread and the main app thread.
Does the thread function itself end? Is the thread doing any UI stuff?

Thanks.
The worker thread communicates with the main thread (UI) on two occassions. It *SendMessage* main to update a progress bar. It *PostMessage* main, which *SendMessage* to view, which calls a function in doc to "close" the thread. When I said close, I am talking about the same function I originally posted above.
I still have no idea what is causing the program to not respond if the user starts click different part of the program. The only thing I can think of is that main ignores the message from the worker thread to close it.

Using SendMessage from one thread to another is a very bad idea. Try either removing that or changing it to PostMessage and see if the problem is resolved.
I don't understand why the worker thread is asking the main thread to close it, but that is another issue entirely.
