external exe return values

I am making a back-up utlility in MFC, which asks for the directory to be archived, and ftp'ed away.

winExec("rar.exe .. blah blah command line arugements",);
that all works fine. The rar.exe is a command line winrar file that is a seperate program, which I don't have the source for. Reading up, it returns 0 when the process is complete, 1 when the process has an input error, and 2 for a file disk error. How can I "catch" this return value, so that the appropriate action ( the ftp process) can be done in my C++ coding afterwards, automatically

Make sure that you have the latest version of the Platform SDK, and that _WIN32_WINNT is defined as >= 0x0500 (only supported on W2K onwards). And it's actually defined in winuser.h, not wingdi.h

Interesting... It is definately present in my version of the SDK (the one that came with VS.NET).

You could try calling it dynamically by doing a LoadLibrary() on user32.dll, then GetProcAddress() to find the function.

I would like to enter strings in an Edit box. The strings will be used to create a list for my List or Combo Box. I have tried InsertString, AddString,
ect. but only generate an assertion error. Does anyone have a very simple working example I could look at?

Hello, i posted a message a while back about a problem with posting some data to a server. I have now built in a buffer in my application to receive server response and the error i get back from my proxy is a 404 Not found and then the url i tried to post to.
Additionally, a 404 Not found error was encountered while trying to use an ErrorDocument to handle the request.

thats what i get back when i try to post data. But i KNOW the url exists cause i'm just cloning the data from the time i posted a message in my browser, the header is EXACTLY the same. I've tried everything, tried to send the lines seperately, tried GET as well as POST, checked the proxy, etc. But it says it cant find the URL... this is just VERY STRANGE to me, especially since i even typed the entire header in the Telnet program, i just connected to my proxy using the windows telnet program and typed in the header, and THAT worked fine. So why doesnt my program work????????????? I'm really stuck here and if anyone could explain to me why its not working, or has any ideas or suggestions they would be highly appreciated. Thanks.

OMG | :OMG:

Did you puts twice \r\n at the end of the request ?
Did you try all the combinaisons possible for the url ?

If I'm not wrong, you musn't request http://www.mysite.com/index.htm but /index.htm or index.htm instead.

HTH !

How do I change JIT debugger from 6.0 to .NET..

Hiya I had 6.0 installed and have now installed .NET. I have been building a project to a certain directory( using the Output Directory in properites ) but the .exe has does not end up in that directory, instead it goes into the debug folder in the project.

I have heard that this is because JIT debugger is still set to 6.0.

So how do I change the JIT debugger from 6.0 to the new .NET..

Thanks,
grahamoj.

In project properties, goto Linker/General. There you can see the name and path of your executable.

By standard it looks like $(OutDir)/$(ProjectName).exe, if not, you might change it to get your programfile in the right dir...

how to make yahoo like chat window?

Hi I am trying to create a chat window like yahoo messenger's chat window.

I am interested to know how to write a component which can show text in different colors and different points.

SPY indicates that yahoo uses a component with classname "ATL:0054E0E0"

is this some standard ATL component?

Any pointers on how to write such component are highly appreciated.

Thank you.

I don't know how the window looks like since I don't use this messenger. But if you want colored text in different fonts then you can use the CRichEditCtrl, which wordpad uses as well (as far as i know)

Someone told me to use CustomDraw.... But how does it work?

Thanx a lot!

The simplest solution is to implement a 1:1 box.

GraphicsPath::Outline problem (GDI+)

grotesque4-Mar-03 5:22

grotesque

4-Mar-03 5:22

I'm having a problem with the Outline method not working after I've applied a certain transformation to the GraphicsPath object (see code below). The problem occurs after the GraphicsPath object is scaled with either the X factor or/and the Y factor set to a negative value (causing flip/mirror).

Code:

GraphicsPath path1;
GraphicsPath path2;

path1.AddString(L"GDI+", -1, &family, FontStyleRegular, 144, rect, &format);
path2.AddString(L"GDI+", -1, &family, FontStyleRegular, 144, rect, &format);

REAL offsetX = rect.GetLeft() + rect.Width / 2.0f;
REAL offsetY = rect.GetTop() + rect.Height / 2.0f;

Matrix matrix;
matrix.Translate(-offsetX, -offsetY, MatrixOrderAppend);
matrix.Scale(1.0f, -1.0f, MatrixOrderAppend);  // negative Y factor causing
                                                    // the path to "flip"
matrix.Translate(offsetX, offsetY + 110.0f, MatrixOrderAppend);

path2.Transform(&matrix);

Pen pen(Color(255, 255, 0, 0));

path1.AddPath(&path2,TRUE);
path1.Outline();   // fails due to the scaling transformation above
                        // the shapes overlap instead om "melting together"

pGraphics->DrawPath(&pen, &path1);

Any light on this problem would be much appreciated. Smile | :)
