if string = NULL or empty so CString::GetAt(0) raise assertion.
So first you need check if it not empty and i < CString::GetLength() Mad | :mad:

I need to write a small app that would manage the Java SDK. but i can't seem to get it to work. The problem becomes bigger since i have to deal with the issue of source files and class files. I think it may have to do with directory.

Beginner question: How do I put the open file name in the status bar?

Here is what I have so far in the ChildFrm.cpp file(this is an MDI program).

int CChildFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CMDIChildWnd::OnCreate(lpCreateStruct) == -1)
return -1;

// TODO: Add your specialized creation code here

//create the status bar

m_StatusBar.Create(this);
m_StatusBar2.Create(this);

//width of text we want to display

CRect textRect;
CRect textRect2;
CClientDC aDC(&m_StatusBar);
CClientDC aDC2(&m_StatusBar2);

aDC.SelectObject(m_StatusBar.GetFont());
aDC.SelectObject(m_StatusBar2.GetFont());

aDC2.DrawText("Line #: ", -1, textRect2, DT_CALCRECT);
aDC.DrawText("File: ", -1, textRect, DT_CALCRECT);

//set up status bar big enough to take the text

int width = textRect.Width();
m_StatusBar.GetStatusBarCtrl().SetParts(1, &width);

int width2 = textRect2.Width();
m_StatusBar2.GetStatusBarCtrl().SetParts(1, &width2);

//Initialize the text for the status bar

m_StatusBar2.GetStatusBarCtrl().SetText("Line #: ",0,0);
m_StatusBar.GetStatusBarCtrl().SetText("File: ", 0,0);

return 0;
}

I need to display the open file name in the status bar. Right now, I get:

Line #:
File:

Is there a command for this? I haven't found one.

Thanks for any hints.

Best,

Fill a string (maybe use CString::Format) with the text you want to display ("File:" + filename) and then output that. You're setting the text as 'File:' but nowhere are you specifying that you want the filename itself to be output as well.

This reminds me of that song "My boomerang won't come back". The answer "first you have to throw it".

Screen Saver Multi-Monitors

I've been mucking about with screen savers and need to add multi-monitor support to it. How would I go about it? Surely there needs to be a

C++

Switch (<<Some Message>>)
Case <<some keyword>>:

//Point setting for single monitor
break;
<br>
Case <<other keyword>>:
<br>
//Point setting for multi monitor
break;

Any help would be greatly appreciated.

Use GetSystemMetrics ( or GetDeviceCaps, I forget ) and ask for the size of the virtual screen. Something like SM_CXVIRTUALSCREEN. I'm making this up, but whatever the flag is, that is how I did it and it works great.

I've used the Multi-Screen code from Ben Bryants screensaver to get the points but I need to know the messages that tell the app what setup the client has at runtime. There must be some message or flag that tells the app whether or not there is more than one monitor and for that message I can implement my point variables. Confused | :confused:

I don't think so, I never found it. I just queried the system for the virtual desktop and worked out the screen dimensions from that.

Help with Help Files

I just learned how to create help files using rtf and hcw.exe, but the process seems a bit clumsy to me. A quick check at www.downloads.com reveals that there are many programms to aid in the creation of help files.

My question is what is the best way to create help files for windows applications. Should I use rtf or html help? Should I use notepad or a specialized program? If the latter is the case, what is the best program to use.

Any suggestions would be appreciated.

I've always used rtf (edit with Microsoft Word or WordPad) and hcw.exe but
for new application, I believe it's neat to use html help. But if you have a
lot of money, you may want to check for RoboHelp Office 2002!
By the way, Microsoft Html help compiler is free. A quick search at MSDN, you will
find everything you need.

1. Create a memory DC. Preferrably one compatible with the target DC.
2. Select your bitmap into this DC.
3. Blit.

Done (modulo cleaning up after yourself).

Also, if the result looks bad, call SetStretchBltMode on the target DC, with a value of COLORONCOLOR.

To be honest, I can't tell the difference, but I could not remember HALFTONE and I could remember COLORONCOLOR. In theory, one is better, but I can't see it.

Strange mutex

Look:

HANDLE h=CreateMutex(NULL, FALSE, "q123");

WaitForSingleObject(h, INFINITE); // doesn't wait here

h is used only in this piece of code - from some MFC dialog based application - with no effect.
Any ideea why?
