After a long time of developing my project (Win 98 + VC++ 6.0 + service pack 3 i think)
compilation suddenly started to crash every time it is creating browse info.
It displays 'Illegal operation' dialog box for bscmake.exe:
BSCMAKE caused an invalid page fault in
module BSCMAKE.EXE at 0177:0040a449.
I tried to clean whole project, including .opt and .clw, restarted Win and build all again, but bscmake is crashing all the time.
Any Idea what can be wrong ? 
Thanks !

I want to make my server program to start everytime i starts the computer. I would like to make it a service.
and upon startup I want the program to show as a systray icon only. When I click on the icon then the command window shows up.
I have a problem because my program is jsut command prompt type of program, not those gui types. So how can I get the window callback proc.
I need help..

Services should not have a user interface. If you need a user interface to control the service, it should be implemented as a separate process and communicate with the service via named pipes or some other communications channel.
There was a security hole (although I believe it's fixed now) where you could send a WM_TIMER message to a service's window in order to elevate your privileges.

now i could create the systray icon. but i can't get those event when i click on it.

Hi all,
I want to Compress the data of BMP in RLE format Using GDI+.
I have tried the Save methode of Bitmap class with giving the EncoderParameters. But didn't work
While enumerating Encoder parameters for bmp codec (SDK sample), I am not getting the values. Does GDI+ not supporting that or I have to upgrade my codec?
My machine is XP and have installed latest Platform SDK.
Thanks in advance

The guys on www.flipcode.com swear by Paul Nettle's memory manager. If you've got any doubts read some of the testimonials and thankyou's in the thread attached to the project.
It's not something I've needed to use myself, but if game programmers (especially console game programmers) who are severly limited on system resources think it's good then I'm guessing it is.
It also has the benefit of being free.

Hi,
When I had a memory leak I tried GlowCode. I found the problem in a matter of minutes, its easy to use and worked really well for me.
They do a free trial for 21 days, you can download it from here I believe....

Hi,
I am writing a serial application to communicate with an external device using RS-232. Requirement is to Write to the external device continuously and read from the device continuously. I have created a thread that performs Read based on the event EV_RXCHAR. On receiving a character i would store it in my local buffer for processing.
I have implemented the write using a 1 millisecond timer in the same thread as read.
The problem is to make this application write and read based on events.
Is it logical to put this write function in a separate thread and will my application be still able to receive Read events?
Please suggest me as to what to be done.
Regards,
Siva

Hi,
a little example
PRINTDLG pd;
DOCINFO di;
int iError;
float fx, fy;
float fPixXWnd, fPixYWnd, fPixXPrint, fPixYPrint;
float fScaleX, fScaleY;
HDC ScreenHdc;
// Initialize the PRINTDLG structure.
memset(&pd, 0, sizeof(PRINTDLG));
pd.lStructSize = sizeof(PRINTDLG);
pd.lpfnPrintHook = NULL;
pd.lpfnSetupHook = NULL;
pd.Flags = /*PD_RETURNDEFAULT |*/ PD_RETURNDC;
//open the Printdialog and get a HDC for the printer
if(PrintDlg(&pd))
{
memset( &di, 0, sizeof(DOCINFO) );
di.cbSize = sizeof(DOCINFO);
di.lpszDocName = "DocName";
di.lpszOutput = (LPTSTR) NULL;
// Begin a print job by calling the StartDoc function.
iError = StartDoc(pd.hDC, &di);
if (iError == SP_ERROR)
{
ASSERT(0);
}
// Inform the driver that the application is about to begin sending data.
iError = StartPage(pd.hDC);
if (iError <= 0)
{
ASSERT(0);
}
//Get the Screen-resolution(1)
ScreenHdc = ::GetDC(NULL);
fPixXWnd = ::GetDeviceCaps(ScreenHdc, LOGPIXELSX);
fPixYWnd = ::GetDeviceCaps(ScreenHdc, LOGPIXELSY);
::ReleaseDC(NULL, ScreenHdc);
//...or get the Screen-resolution(2), not tested
fPixXWnd = ::GetSystemMetrics(SM_CXFULLSCREEN);
fPixYWnd = ::GetSystemMetrics(SM_CYFULLSCREEN);
//Get the Printer-resolution
fPixXPrint = (float)::GetDeviceCaps(pd.hDC, LOGPIXELSX);
fPixYPrint = (float)::GetDeviceCaps(pd.hDC, LOGPIXELSY);
//the alignment for your window-coordinate
fScaleX = fPixXPrint / fPixXWnd;
fScaleY = fPixYPrint / fPixYWnd;
....
e.g. you draw your Bitmap to your view with
StretchBlt(hdcWnd, 10, 10, 100, 100, hdcBmp, 0, 0, 50, 50, SRCCOPY);
now write the following for your Printer
StretchBlt(hdcPrint, 10*fScaleX, 10*fScaleY, 100*fScaleX, 100*fScaleY, hdcBmp, 0, 0, 50, 50, SRCCOPY);
HTH

Hi !
I posted a question yesterday about printing a postscript file in C++. I still need more informations about this. How can I, in C++ : open the printer device, write the file to the open handle, and close the printer device ?
Thank you for your help !
Jerome

Off the top of my head:
OpenPrinter
StartDoc
WritePrinter
EndDoc
ClosePrinter
if you need further advise, let me know. I've done it in one of my projects.

Thank you for your answer. But I guess you are mentionning MFC functions, right ? I was trying to do it in standard C++ (I didnt mention it clearly in my question).
Thank you for your help anyway,
Jerome
|
|
|
|
|
Those are standard Win32 functions, no MFC needed. Did you try looking them up in MSDN?
Joel Lucsy
|
|
|
|
|
Actually, my application has to be crossplatform, so I'm not allowed to use any Win32 functions. This is why I wanted to do it using standard C++ !
Jerome

|

Ah, crossplatform, that is an entirely different matter. Since everything is a file under *nix you may be able to use straight file operations as long as you know how the printer is connected. Note, however, that Win32 and *nix completely differ on how printers are handled, you will have to right different code for each.
For *nix, look for the CUPS package. This is the only thing I know of that may make things easier for that platform.

Hi Himanshu
I know 2 ways:
- move your program (link) to the autostart folder
- write your program as service and start the service always -> systemsettings (I think the better way)
Regards
Frank

There is no way, short of replacing system files, to guarantee that your application will be the first to start. Items in the startup folder are loaded after all services have been loaded. Even if it were a service, you could only guarantee that it start AFTER another application, but never before.
