Before I setup the Printer Setup dialog I wanted to set the paper size and orientation ect.
What I did was:
CPrintDialog PDlg(TRUE);
GlobalAlloc(GMEM_MEVABLE, sizeof(DEVMODE));
DEVMODE* pDevMode = (DEVMODE*) GlobalLock(PDlg.m_pd.hDevMode);
pDevMode-> ...
...
GlobalUnlock(PDlg.m_pd.hDevMode);
PDlg.DoModal();
According to MSDN this should be enough to initialize things before the call to DoModal, right?
Thanks for any suggestions.

I'm interested to know what version control ppl use at work. I'm currently evaluating visual sourcesafe with sourceoffsite for distributed team collaboration on code and also cvs on a linux machine with windows gui clients. One is free and the other is not but has anyone had any experiences with both or use something else?

We use SourceSafe and SourceOffsite here. biut I'm afraid I've got no experience of CVS.
This topic has been discussed pretty extensively in the Lounge, so I'd suggest a quick trail through the posts (don't worry, there's only 77,000 of them  ) would be a good starting point.
Just try setting the filter to "SourceSafe" or "version control" and you'll find plenty of information.

We have used WinCVS at work and found that on many occations it 'Lied' to us about diffs in files.
We also us Source Safe on projects where we use Visual Studio as it is conviently intergrated. A warning however if the SS database is on a UNIX server, be sure that the file system which contains the 'sepository' is not subject to quotas. If a user overruns the soft quota during the checkin process, it screws up the repository because the file will be integrated and the history update may not happen. This happened a number of times on a previous project I worked on and now I have insisted that source code is free of quotas, because we know that no matter which system you use the repository will only grow and not shrink.
Happy programming!!

I have imported office 97 (or maybe XP), no dll hell any more, now it is called com hell;
#import "D:\Microsoft Office.97\Office\Mso97.dll"
#import "c:\Program files\Common Files\Microsoft Shared\VBA\VBE.DLL"
#import "C:\Program Files\Common Files\Microsoft Shared\VBA\VBEEXT1.OLB"
#import "D:\Microsoft Office.97\Office\MSWORD8.OLB"
As i would like to support different office versions, i need "a bit" changed headers, so there wouldnt be any namespace conflict between different versions of imported librarys.
After checking tlh, i have encountered on #pragma start_map_region. What does it do?
|
|
|
|
|
The only thing I can think of is that start_map_region is a macro. Try searching for a definition...
Otherwise I'm afraid I can't help.

pDC->Ellipse(&rc); is consuming over 70% of the time spent in your two functions (using a rectangle with size 200 by 200 and a memory DC)
You are painting the same areas over and over again, excluding the outermost part of the ellipse.

If you are taking in events, look for DocumentComplete (DISPID_DOCUMENTCOMPLETE) (DOM has been built, and is ready to be read/manipulated).
If not, check the readystate of the document with IHTMLDocument2::get_readyState

Hi,
I just encountered a TransmitFile API call
Have anyone used it before.. i mean i want to

Also, my server is a Linux server and i've written a
small program there.. how should i use this with the

Hi,
I want to know how to programatically create key's
and values in the Registry..
A small example would be helpful
Thanks in advance
Sameer

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,
thundercatzlair

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));
