char somechar = 30;
now in java when i write:
char somecharinJava = 30;
it is not the same, it returns string representation..
how can I produce equivalent of "char somechar = 30; // in c++", in java?

char somechar = (char)30;
int someint = (int)somechar; -> return 30

I'm confused, this code:
char ch = 30;
Behaves in, nearly, the same way in both Java and C++, which is: the value of ch is set to 30.
The only difference is that char in Java is a 16 bit type that holds Unicode values, while char in C++ is an 8 bit type.
Did you perhaps mean this:
<code>Java:</code>
String s = 30;
<code>C++:</code>
string s = 30;
If that is the case, then you can take a look at the standard C++ implementation of a string [^]. This should help you to create a descandant of that type with an overloaded '=' operator that translates 30 to "30".

I'm not sure if this is the correct forum but ...
I'm trying to find out if VC++ supports pipe select operations.
In case my terminology differs from yours, by pipe select operation, I mean: the ability to block-wait for data to arrive on any one of a group of pipes.
Thanks

No, the pipe in Win32 works differently from Unix, and you cannot use 'select' on it. Instead you would need to use the Win32 version of pipe (created with CreatePipe), and then use the standard WaitForSingleObject/WaitForMultipleObject functions to do the equivalent of a pipe select.
You may also be able to use an external library, such as cygwin, to provide unix-style pipe emulation.

MFC MDI project:
I didnt name my project with the final name in mind, and now i cant seem to change the title bar of the project. In project settings i was able to give a suitable new name to the exe but the title bar still has the name of the project in it, even though I rebuilt the prj. Please tell me theres some trivial way of changing the name in the title bar....
I looked into the rc file with notepad but dont see anything I can change there, (I dont really know what I'm looking for.) Anyways is is safe to edit the rc file?
Thanks,
ns
I tried SetWindowText in mainfrms OnCreate and also in OnInitialUpdate of the view...didnt work.
Also did cs.lpSzName in PreCreateWindow....thats no good too.

In the resource view, open the String Table and edit the IDR_MAINFRAME caption to what you want to appear in the titlebar of your project.
You might also want to change the AFX_IDS_APP_TITLE string caption to something different as well since calling AfxMessageBox(...) will display the AFX_IDS_APP_TITLE string caption in its titlebar. That should do it.

Well, that works great, but now, in the title I get:
MyGoodProjectName - OldPrjName1....sort of like thats the name of the document or view or something. I tried changing the IDR_STRAINTYPE string but thats not it apparently. So the old prj name is still sneaking in....
Ideas?
Thanks,
ns

By looking to IDR_STRAINTYPE, you are on the right track. That is the string that you need to change. I built a quick app named "newMFC" and I have its "TYPE" string resource below:
\nnewMFC\nnewMFC\n123 Files (*.123)\n.123\nnewMFC.Document\nnewMFC.Document
Change the first "line" or section of this string to what you want the document to be called by default. For instance, if I wanted it to show "New Document" I would change the above line to:
\nNew Document\nnewMFC\n123 Files (*.123)\n.123\nnewMFC.Document\nnewMFC.Document
DO NOT remove the new line characters (\n) in the process. That should do it.
For future reference, below is what each section is for, corresponding to the MFC App Wizard:
1) \nnewMFC - Document Type Name
2) \nnewMFC - File new short name
3) \n123 Files (*.123) - The filter name
4) \n.123 - The actual file type filter
5) \nnewMFC.Document - The file type ID
6) \nnewMFC.Document - The File type Long name
I hope that fixes things for you. If I understand your problem right, it should. Good luck with the rest of your project. 
Happy Programming!

By golly!
You have done it again!!! I had eralier tried exactly what you say to do, but I hadnt closed the editbox (after I changed the entry so the change didnt take effect) before building the proj again which is why I saw no difference. But this time I edited the resource , saved it, closed the editbox and then built and ran....viola! I appreciate your careful explanation of the various sections. It still likes to tack on a "1" at the end of the title as in : MyProject - CorrectNAme1
--- which is quite acceptable. SO, many many thanks again!

One more thing since you mentioned it. It may or may not matter much, but I think it looks a little nicer if there is a space between the new document name and the number. This "New Document 1" instead of this "New Document1". If you would like the first effect, just insert a space after the name and MFC will tack on the number after the space which, just according to my preference, looks a bit nicer.
\nNew Document \nnewMFC... PROMPTS "AppName - New Document 1"
instead of
\nNew Document\nnewMFC... PROMPTS "AppName - New Document1"
Just thought you might be interested. Once again, good luck with your project!

hy, try to overwrite OnEraseBkg, and also OnCTLColor
try something like this:
HBRUSH CBaseView::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
switch (nCtlColor)
{
case CTLCOLOR_STATIC:
case CTLCOLOR_LISTBOX:
case CTLCOLOR_BTN:
pDC->SetBkColor(GetSysColor(COLOR_BTNFACE));
return (HBRUSH)m_grayBrushPtr->GetSafeHandle();
break;
default:
return CFormView::OnCtlColor(pDC, pWnd, nCtlColor);
break;
}
}

there is an easy was aswell
take a variable of type CBrush at class level like
CBrush m_Bursh;
initiate it in OnInitDialog like
m_Bursh.CreateSolidBrush(RGB(0,0,0));//OR ANY OTHER COLOR u WANT
override the WM_CTCOLOR message handler
and add this line to its implemention
HBRUSH CBaseView::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
return m_Brush;
}

Hi.
I am trying to use the CImage class from ATL to handle images in my GDI game.
I manage to make it draw the images, or at least some formats. It says in the documentation that the CImage::Draw function is supposed to support both transparency and alpha channel. But I can't seem to make that work.
I was wondering if it's just the format that I save my images in that is wrong? I have tried different PNG formats and GIF, but none work correctly. As far as I understand the documentation I am supposed to be able to create a PNG containing transparent color and alpha channel and the Draw function will take care of the rest when I call it... Is that the case?
Does anyone know what format I have to save my images in to make them work properly? I tried to save the image with transparency and alpha channel as PNG-24 (from Photoshop), but the transparent color is just semi-transparent when I render it in my game. Anyone know what's wrong?
Thanks.

Hey everyone,
is it possible, unload any dll module (not my) from any strong system process e.g.
rundll32 or svchost.
How can I do it ?
Sorry for my english and thanks for advice

I do not know of a way of telling another process to unload its dynamicly linked binaries. In fact if you could tell any arbitrary binary to load and unload dynamic bindings outside of the process that could be an exploit (tell it to unload svchost, put the malicious version in, tell it to load it).
Why do you want to unload rundll32 or svchost? Instead of asking a specific question maybe you should step back and see what you are really trying to solve.

I'm trying write some little application whereby I can unloading and deleting malicious modules - dll's like keyloggers or adware components. Part of that pests are loaded when starts OS and are modules of e.g. rundll32.exe.
What can I do, to delete thats dll's ?

Unfortunately Windows has a habbit of locking files mapped into memory. Why it does this I'm not sure since it shouldn't matter what happens to the binary after it is read into memory.
One thing I've been meaning to look into is how to hook into the pre-boot and boot process. For instance when a kernel patch is applied to the OS you have the very same problem (you can't copy the new kernel bins while the kernel is running). What happens is you tell the boot loader to copy and configure files before the kernel is fully loaded. Especially with some classes of malware you really need a "true" single user mode where one can make manipulations to the system by hand without fully initalizing the kernel.
I like the fact that anti-virus software is starting to key into the fact that malware and spyware are just as bad as any virus (in fact one could term them as trojans). I'm not trying to discourage you but some of this stuff is real harry stuff requiring knowledge of the internals to fight.

That's because windows creates a file mapping to the executables instead of reading it all into memory in one sweep.

If you want to know how to map a file, look up the methods CreateFileMapping and MapViewOfFile in the Win32 API.
But Tom was right about your original question, you can't tell a process to unload dll's.
