I have a class delived from CWnd and in OnNCPaint is the code for drawing color edge(border) of control. I need draw scrollbar myself because this code is not optimal(it blink  ) :
void CMyClass::OnNCPaint(){
CWnd::OnNCPaint();
CWindowDC dc(this);
CRect rect;
GetWindowRect(rect);
dc.Draw3dRect(0,0,rect.Width(),rect.Height(),RGB(0,255,0),RGB(255,0,0));
}
Thanks!

Hmmm... I don't know what type of control you're trying to paint, but scrollbars usually are inside the client area (I think).

I thought so too. They do flicker quite a bit though while in the client area...I don't know if non-client area would be any better though. Do you think it's because the entire client area is getting invalidated instead of just the drawing area inside the client area...?

Well, it depends. 'Internal' scrollbars maintained by Windows are drawn outside client rect. If you create them yourself as controls, they will cover parts of client area.

If internal scrollbars are drawn outside the client rect, this means they shouldn't flicker right..?
I've never actually used internal scrollbars...i've always liked the freedom of adding buttons between the scrollbars. However they are usually created inside the client area and get redrawn on every invalidate() which causes crazy flicker. Do the system scrollbars flicker? Cuz i'd do away with my buttons for the trade off of no flicker.
Cheers!

The reason they flicker is that you're drawing the client area and then windows draws the scrollbars on top.
Theres an article somewhere on MSDN about why scrollbars are drawn internally and hence can't be customised.
when i did a sort of skinned app, the only way i could get scroll functionality with nice looking scroll bars was to bodge a CFormView onto my dialog, and then use a custom written control to be a scrollbar, and scroll the view window internally. it was messy but it worked.

Sorry to dissapoint you all with my lack of a witty or poignant signature.

I don't think you can paint the scrollbars yerself in the OnNCPaint...
You probably have to derive clases from CScrollBar make them owner drawn and do it that way.

Hey guys
The function below is being called by rundll32.exe but whenever i run it i get a memory violation saying :-
The instruction at "0x77f52ff9c" referenced memory at "0x002e2afd. The Memory could not be "read"
// DLLVerifySignature - Allows Verification on double click
bool DLLVerifySignature(HWND hwnd, HINSTANCE hinst, LPTSTR sFileNameAndPath, int nCmdShow)
{
CFullCryptFunc FullCrypt;
FullCrypt.FullVerifySignature(sFileNameAndPath);
FullCrypt.~CFullCryptFunc();
return TRUE;
}
The funtion i call in the FullCrypt class works fine as when i call it from another part of the program i have no problems im guessing that teh problem occurs because the software is not properly initalised when it trys to call this.

You'll have to dig deeper - run your .dll under a debugger. Use rundll32.exe as 'Executable for debugging session' under Project Settings/Debug.
When the program crashes, you'll be able to have a look at the stack, local variables, globals, etc.

So i have a char[20] like "foo foobar foo2" and I want to get
A = "foo"
B = "foobar"
C = "foo2"
if the words could be any length, what is the best way to do this?

what about the extraction operator:
char curRecord[20];
char cDay[3];
while(!osMyFile.eof()) // we go through each line in the file
{
osMyFile.getline(curRecord,20); // read time value
curRecord >> cDay;
cout << curRecord << "\t" << cDay << endl;
}

i am sorry, but i don't get it what do you mean?

He is just saying that strtok is a nice simple routine while strstream is this huge library with a lot of extra baggage.

I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk?

o.k. so I have:
while(!osMyFile.eof()) // we go through each line in the file
{
osMyFile.getline(curRecord,20); // read time value
ins >> intDay;
ins >> intTime;
ins >> strOnBay;
cout << intDay << "\t" << intTime << "\t" << strOnBay << endl;
}
this is so close to working -- the only problem is that, while it loops through the file, it keeps putting the same value in intDay, intTime and strOnBay each time . . . (i.e. they never change)
thanks,
tim

Where did that ins come from? Rewrite your code like this:
...
osMyFile.getline(curRecord,20);
<font color=#ff0000>istringstream ins(curRecord);</font>
ins >> intDay;

I do I add external dependies to the project?
|
|
|

Could you explain yourself a little longer? If you want a project to depend on say some external .lib just add this file as a regular source code file. The IDE will not only link the library but also take care of relative last modified dates.

Hi everybody!
I'm writing program, that will go to some web site, log in, and retrieve some data. I know how to get data from web server, that does not reqire any authentication.
Web page I'm trying to log in is a standard form where you can enter username and password. Below is part of Java script of that page:
function secure_login(form)
{
// Prepare session cookies for secure login
document.cookie = "uid=" + escape(form.UserID.value) + "; path=/; domain=.somedomain.com";
document.cookie = "pwd=" + escape(form.Passwd.value) + "; path=/; domain=.somedomain.com";
document.cookie = "redirect=" + escape(form.redirect.options[form.redirect.selectedIndex].value) + "; path=/; domain=.somedomain.com";
location = "https://www.somedomain.com/secure_login.html";
}
After login server will redirect me to another page (let's say, Page2), and I want to do some work with it ("POST"s and "GET"s).
As I understand, when doing "POST" to Page2, I should somehow specify these cookies in HttpRequest. Am I right?
If yes, how should I do that? If there is any example, I'll greatly appreciate it!
Kosta.

Are you using raw Winsock (sockets) or rather Wininet? If the latter, <a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vcmfc98/html/_mfc_cinternetsession.3a3a.setcookie.asp">CInternetSession::SetCookie</a> might just be what you're after.
